Health care workers in developing countries are highly susceptible to workplace associated TB infection due to the long hours spent with patients who have undiagnosed or untreated TB cases, poor infection control measures and poor isolation of TB cases in health care facilities. Objective: To assess the implementation of tuberculosis infection control measures among health care workers at the Greater Accra Regional Hospital. Methods: Descriptive cross-sectional study design using both quantitative and qualitative approach was employed in this study. One hundred and thirty seven (137) Health Care Workers (HCWs) and seven (7) Key Informants participated in the study. The HCWs were proportionally selected from each job category using simple random sampling technique. Quantitative data were obtained using semi-structured questionnaires, and triangulated with direct observation and Key Informant Interviews. Descriptive analysis, univariate and multivariate logistic regression were carried out using STATA version 14.0. Qualitative data were transcribed verbatim and analyzed using thematic analysis. Results: More than half, 88 (64.2%) of the HCWs exhibited good knowledge, while a similar proportion 83 (60.6%) also exhibited good practice. Being female (COR= 2.06, 95% CI: 1.00-4.22) and married (AOR= 3.19, 95% CI: 1.11-9.13) were significantly associated with knowledge. Having good knowledge (AOR = 5.83, 95% CI: 2.07-16.43) and being a Doctor (AOR= 7.91, 95% CI: 1.73-36.18) were significantly associated with iv University of Ghana http://ugspace.ug.edu.gh good practice. Qualitative data showed that HCWs perceived screening of patients as the main promoter of effective implementation of Tuberculosis Infection Control (TBIC), while inadequate Personal Protective Equipment (PPEs), absence of staff screening. small waiting area and improper ventilation were the major inhibitors. Conclusion: The overall level of knowledge and practice was good among HCWs. Knowledge and job category were the main significant predictors of TBIC practice. Sustained TBIC practice was perceived to be largely promoted by availability of screening of suspected TB patients, while inadequate PPEs and absence of staff screening for TB were perceived to be the major inhibitors. Hence, facility management should work closely with the TB Coordinator to ensure periodic staff screening exercise and provision of needed logistics.

The World Health Organization in 2016 reported a global TB incidence of lOA million (5.9 million men, 3.5 million women and I million children) with an incidence rate of 142 per 100,000 populations in 2015. Africa recorded an incidence of 2. 7 million \\ ith an incidence rate of275 per 100,000 populations. This was the highest incidence rate amongst all the six WHO regions. Ghana, however, recorded an incidence of 44,000 with an incidence rate of 160 per 100,000 populations (WHO,2016). The global mortality of TB was 1.4 million with a mortality rate of 19 deaths per 100,000 populations. In Africa, 450,000 deaths were recorded with a mortality rate of 45 per 100,000 populations. Again, Africa had the highest rate amongst all the six WHO regions. Ghana recorded 10,000 deaths with mortality rate of 37 per 100,000 popUlations (WHO, 2016). In 2015, an incidence of 9,977 was recorded among Health Care Workers (HCWs) in 67 countries. of \\hich South Africa emerged as the second highest, recording 2,095 cases (WHO. 2016). A report by Ghana's National Tuberculosis Programme in 2011 revealed that about three hundred health care workers (HCWs) in Ghana were infected with tuberculosis (NTP, 2011, unpublished data). University of Ghana http://ugspace.ug.edu.gh A Meta-analysis revealed that health care workers have three times (3x) average annual risk of tuberculosis infection than the general population across all settings (Baussano et aI., 2012). In three districts in Kwazulu-Natal, South Africa. 112 TB cases were detected among 1,313 health care workers studied (Tudor et aI., 2014). A study in Kigali, Rwanda showed that out of every three health care worker, almost two were infected with nosocomial TB infection (Rutanga et aI., 2015). The spread of Mycobacterium tuberculosis in health facilities to both patients and health care workers may be due to poor infection control practices within the facilities. Additionally, the long waiting time spent by patients in various health facilities is a contributory factor to the high rate of tuberculosis in health care settings (Escombe et aI., 2010). This is because patients with undiagnosed or untreated TB mingle with other patients and health care workers thereby increasing their risk of infection. Implementation of infection control measures as an essential component of health care provides the basis for TB risk reduction among health care workers, patients and other facility users. The WHO, in a bid to achieve this, established an implementation guideline, which was updated in 2009 to curb TB infection in health care settings. The objective of the program was to ensure prompt detection of infectious patients, airborne precautions and treatment of people with suspected or confirmed TB (WHO, 2009). The policy covers managerial/administrative, environmental and personal protective measures. The managerial and administrative measures are the first and most important level in TB infection prevention and control (Chen et aI., 2016). It focuses on reducing the droplets of Mycobacterium tuberculosis in health care settings by eliminating its generation 2 University of Ghana http://ugspace.ug.edu.gh and risk of exposure. Environmental measures seek to provide an infection free environment for both health care workers and users by preventing spread as well as reducing the concentration of the TB bacterium in the air. The third level, which is the personal protective measures. involves the use of respirators to protect users from inhaling the Mycobacterium tuberculosis. It serves as the last line of defense in the event of failed manageriaVadministrative and environmental protective measures (WHO, 2009). The implementation of Tuberculosis Infection Control (TBIC) is largely dependent on health care workers because of their role as front liners in health service delivery. However, studies have confirmed that such a function has greatly been limited in many health facilities due to poor knowledge, poor training of health care workers on the implementation of TBIC and insufficient provision of personal protective equipment amongst others (Baussano et aI., 2012). This study therefore sought to assess the implementation of Tuberculosis Infection Control measures among health care workers at the Greater Accra Regional Hospital using both quantitative and qualitative research approach. 1.1 Problem Statement In Ghana, about 300 health care workers (HCWs) were infected with tuberculosis in 2011 (NTP. 2011. unpublished data). It has been identified that poor ventilation and air recirculation alongside poor infection control and isolation practices are often contributory factors to TB transmission in health care setting (Castel a, Silva, Ferreira, & Nienhaus, 20 II). Long waiting time of patients with undiagnosed and untreated TB cases at health 3 University of Ghana http://ugspace.ug.edu.gh facilities also increases health care workers' susceptibility to TB infection (HeyseIl, Shenoi, Thomas & Friedland, 2011). Infection control is regarded as a critical preventive measure in TB care. In 2009, the WHO revised the guidelines for the implementation of TB Infection Control (TBIC) in health facilities to protect other patients and to reduce TB risk among health care workers (WHO, 2009). Ghana's Ministry of Health (MOH) also adopted and implemented the WHO TBIC policy due to the heightened concerns about unacceptable infection control practices throughout the country (MOH, 2009). [he implementation of the Tuberculosis Infection Control (TBIC) is largely dependent on health care workers' knowledge, attitudes and practices. Unfortunately, many health care workers perceive it as a burden due to work overload and the use of personal protective measures as uncomfortable thereby posing challenges to implementing TBIC (Efstathiou, Papastavrou, Raftopoulos, & Merkouris, 201 I). A national survey in Ghana by Amo-Adjei (2013) revealed that health system factors such as poor funding, poor infrastructure, friction between clinicians and public health professionals. weak monitoring and evaluation practices were some of the barriers to effective implementation ofTBlC. A study at the Tema General Hospital by Codjoe (20 12) also showed lack of wards for isolating TB patients, lack of protective equipment and overcrowding of patients at Out Patient Department (OPD) and inadequate training as factors hindering implementation ofTBIC in the facility. Another study in Urban Takoradi Ghana reported that isolation ofTB wards in addition to "excessive" use of PPEs (gloves) by health professionals when attending to TB patients served as basis for stigmatizing 4 University of Ghana http://ugspace.ug.edu.gh against the patient (Dodor & Kelly, 2010). As such, isolation of TB patients was not effectively practiced. The quality of environmental factors and service factors (frequency of screening. availability of TBIC materials, availability of TB laboratory for testing and reporting) influencing the implementation ofTBIC are however unknown. Thus, this study sought to assess the practices of Health Care Workers (HCWs) on Tuberculosis Infection Control (TBIC), and explore service factors and environmental factors influencing its implementation at the Greater Accra Regional Hospital using a mixed method approach. 1.2 Conceptual Framework on Implementation of TBIC Figure I below shows the relationship between the various aspects of implementation of Tuberculosis Infection Control (TBIC) among health care workers. These factors include facility-level managerial activities alongside administrative, environmental and personal protection measures. Facility-level managerial activities comprise the systems in place to ensure appropriate set up and implementation of the three aforementioned TBIC measures at the facility level. It includes leadership, planning. coordinating activities and groups, monitoring and evaluation, development of policies and procedures, facility assessment, and participating in research works in line with the national TB agenda. It is usually fused into the administrative measures. Administrative Measures is the first line of defense for the implementation of TBIC (Menon. 2013). It focuses on preventing droplet nuclei containing mycobacterium University of Ghana http://ugspace.ug.edu.gh tuberculosis from being generated in the facility thereby reducing exposure of patients and health care workers to TH. It therefore requires prompt identification of TB suspects (triaging), separation and treatment of people with TB symptoms, and minimizing time spent in health care facilities. These measures tend to influence both the environmental and personal protection measures. Administrative and managerial factors can be grouped into two; service factors, and human resource and leadership factors. Service factors are factors directly linked with TB care. These include availability ofTBIC materials, availability ofTB laboratory for testing and reporting, frequency of TB screening, and availability of an isolation ward for separation of infectious patients. Availability of TBIC materials such as TBIC plan, policies and procedures, PPEs and Information, Education, Communication (IEC) materials may enhance sustained implementation of TB Infection Control among HCWs. They know what is expected of them and how to go about it in order to reduce TB infection in the health care facilities. The human resource and leadership factors are factors that indirectly affect the quality of the implementation ofTBIC measures among health care workers. These include training of HCWs on TBIC, education of patient on cough etiquettes and respiratory hygiene, and ~upervisory activities. These factors reduce TB transmission in health care settings by making health care workers conscious of TB related issues and the appropriate ways to handle them Yo hile proper supervision ensures effective implementation ofTBIC Measures. Environmental Measures include ways of reducing the concentration of Mycobacterium TB droplet nuclei in the air and controlling the direction of the infectious air (WHO, 2009). 6 University of Ghana http://ugspace.ug.edu.gh It is largely tailored towards ensuring quality ventilation system, which in turns reduces TB infection in health facilities. An effective administrative and facility-level managerial activity is key to ensuring proper environmental measures since the administrative and managerial activities are responsible for the provision of the ventilation equipment. Personal Protective Measures involves the use of Personal Protective Equipment (PPEs), like particulate respirators and masks. to protect HCWs from TB infection. It is used together with the administrative measures and facility-level managerial activities, and environmental measures where there is an increased risk of transmission (WHO. 2009). Adequate provision of personal protection equipment as well as training on its appropriate use may encourage usage among health care workers (WHO, 2009). It has been shown that many HeWs are unclear about the use of respiratory protection in terms of when, how and which type is needed in specific situation (Peterson, Novak, Stradtman. Wilson, & Couzens. 2015). Effective supervision may also reduce the rate of non -compliance to the use of personal protection equipment among HCWs.

Thus, this study will provide quantitative and qualitative data on the implementation of Tuberculosis Infection Control (TBIC) measures among health care workers at the Greater Accra Regional Hospital, Ghana. This would inform policies on tuberculosis infection control as the challenges health care workers face in implementing TBIC would be unearthed. It would also provide recommendations to health facility heads on health service delivery factors needed to support health care workers in implementing TBIC. This study would also unearth the practices of health care workers in implementing the tuberculosis infection control measures, which may enable facility heads to undertake effective monitoring and evaluation to reduce nosocomial TB transmission among health care workers, patients and relatives. 1.4 Research Questions I.

It highlights the following themes tuberculosis epidemiology, TS infection in the health care settings, TS infection, prevention and control strategies, Health Care Workers' (HCWs) practices of TSIC policies and measures, and Challenges faced by HCWs in the implementation of TSIC measures. 2.1 Tuberculosis Epidemiology Tuberculosis is a major global health problem and of public health concern. According to the World Health Organization, in 2015, TS ranked (above HIV/AIDS) among the top ten causes of death worldwide (WHO, 2016). Despite the numerous measures employed to militate against this infectious disease, in 2015, the new cases ofTS recorded globally were about 10.4 million, comprising 5.9 million men, 3.5 million women, and 1.0 million children (WHO, 2016). The global incidence rate was 142 per every 100,000 populations. The WHO South-East Asia Region recorded an estimated incidence of 4, 740,000 TS cases, \\ ith an incidence rate of 246 per 100,000 populations. The WHO African Region, with total incidence of 2,720,000 cases, recorded the highest incidence rate of 275 per every 100,000 populations (WHO, 2016).The incidence in Ghana was 44,000 cases with an incidence rate of 160 per every 100,000 popUlations. In terms of mortality, an estimated 1.4 million TB deaths were recorded in 2015 globally. Sixty percent (60%) of these deaths were recorded in six (6) countries only: India, 11 University of Ghana http://ugspace.ug.edu.gh Indonesia, China, Nigeria, Pakistan and South Africa. The global mortality rate was 19 deaths per 100,000 populations. The WHO African Region alongside WHO South-East Asia recorded the highest total deaths in 2015 (an estimated 450,000 and 710,000 deaths respectively). In terms of mortality rate, the African Region recorded the highest rate of 4S per every 100.000 populations followed by the South-East Asia Region with a rate of 37 deaths per e.very 100,000 populations. Ghana recorded about 10,000 deaths with a mortality rate of 37 deaths per 100,000 populations (WHO, 2016). This makes TB a poverty-related disease. mainly affecting the poorest regions in the world. 2.2 Tuberculosis Infection in tbe Healtb Care Settings The risk of contracting the Mycobacterium tuberculosis increases with the frequency of contact with people infected with the disease. This makes health care settings one of the most common locations for TB transmission. The risk of exposure to TB in health care facilities increases as health-care facilities become overcrowded with undiagnosed and infectious TB patients who spend long hours waiting to receive medical care. Improper environmental infection control due to poor ventilation, and poorly enforced TB infection prevention and control measures are among the contributory factors to health care setting TB infection (Grobler et aI., 2016). In 2009. the WHO reported that the TB incidence rate of people working in health care settings was higher than that of the general population (WHO. 2009). In a bid to mitigate this. the WHO also came out with a policy on TB infection control in health-care facilities, congregated settings and household. The objective of the policy is to "provide Member States with guidance on how to reduce the risk ofrB transmission in healthcarefacilities. 12 University of Ghana http://ugspace.ug.edu.gh congregate settings and households. and how to prioritize TB infection control measures" (WHO, 2009). In 2015, an incidence of 9,977 cases among health-care workers were reported from 67 countries, with China and South Africa accounting for 31 % and 21 % of these cases respectively (WHO, 2016). A research by Adams and colleagues reported that generally, health care facilities in South Africa have less adequate or inappropriate infection prevention and control measures established to protect their employees (Adams et ai., 2013), despite the international policy recommendations to mitigate TB in such settings (WHO, 2010). In Ghana, however, about 300 health care workers were infected with tuberculosis in 2011 (NTP, 2011 Unpublished data). 2.3 Infection Prevention Control in Health Care Settings Nosocomial infections, also known as "healthcare-associated infections," are the infections that occur due to prolonged patient stay in health facilities (Brusaferro et ai., 2015). These infections could be picked from other patients, equipment and even through the air. It can increase the length of stay of patients in hospital thereby increasing hospital cost and prolonging recovery. Infection Prevention Control (lPC) has been shown to be of utmost importance in health care settings and in healthcare because of its potential benefit in reducing the burden of disease on patients, facilities and the nation at large. Thus, health care organizations are taking pragmatic steps to improve the prevention and control of nosocomial infections. In, 2009, the Ministry of Health in Ghana revised its IPC policy with focus on improving environmental health and other hygienic measures in health care settings. It recommended that a\l facility based infection prevention control programmes should be fused with other 13 University of Ghana http://ugspace.ug.edu.gh important programmes such as TB programmes, quality assurance, environmental and occupational health, communicable disease control among others (MOH, 2009). Previous study has shown that isolation precautions are essential in reducing transmission of infectious agents within health care settings (Raka, 2010). 2.4 Tuberculosis Infection, Prevention and Control Measures Tuberculosis is a leading cause of morbidity and mortality globally, especially amongst developing countries (Zaman, 2010). Due to TB's global impact, various measures and policies have been developed over the years to fight it. The quest to end epidemics including TB is now a prominent part of strategies developed by global bodies, including the United Nations Organization (UNO) and the World Health organization (UNO, 2015; WHO. 2016). The Directly-Observed Therapy Short course (DOTS) has been a leap forward in controlling tuberculosis. It has become the basis for treating TB in many countries. From the year 2000 to 2015, two major global measures were implemented to reduce the burden ofTB: the Millennium Development Goals (MDGs) (2000 - 2015) that sought to "halt and reverse" TB incidence by 2015 (MDG 6, Target 8), and the Stop TB Strategy (2006-2015) by focusing on halving TB prevalence and TB mortality by 2015 compared with their levels in 1990, in addition to achieving the MDG target. According to WHO, the MOO target was achieved on a world-wide basis. Further, there was a 47% fall in global TB death rate between 1990 and 2015, with most improvement occurring after 2000. It also indicated that the prevalence rate fell by 42% between the same periods (WHO, 2016). After 2015, the UN initiated the Sustainable Development Goals (SDGs) - from 2016 to 14 University of Ghana http://ugspace.ug.edu.gh 2030 _ and the WHO is implementing the End TB Strategies (2016-2035). Target 3.3 of the Sustainable Development Goal 3, focuses on ending epidemics - including tuberculosis _ by 2030 (UN, 2015). The WHO End TB Strategy also seeks to reduce 18 deaths by 95% and TB incidence by 90% from 20 I 5 to 2035. The overall goal is to reduce incidence to 10 new cases per 100,000 populations (WHO, 2016). Tuberculosis infection control involves employing diverse "measures aimed at minimizing the risk ofTB infection transmission within populations" (WHO, 2009). It involves early and rapid diagnosis, and proper management of TB patients. As part of the WHO's Stop TB Strategy, a policy for the implementation of sound TB infection control, with focus on control in health-care facilities and congregated settings and households, was introduced in 2009 and adopted by Ghana's Ministry of Health. The policy covers three main levels of controls: Administrative Measures, Environmental Measures, and Personal Respiratory Protection. It also covers managerial activities that facilitate the implementation of these controls. 2.4.1 Administrative measures Administrative Measures is the first line of defense for the implementation ofTBIC in any setting regardless of available resources (Menon, 2013). They are the most effective and least expensive intervention (Nardell & Dharrnadhikari, 2010). It focuses on preventing droplet nuclei containing mycobacterium tuberculosis from being generated in the facility thereby reducing exposure of patients and health care workers to TB. It therefore requires prompt identification, separation of infectious patients, control of spread of pathogens, and 15 University of Ghana http://ugspace.ug.edu.gh treatment of people with TB symptoms, while minimizing time spent in health care facilities (WHO, 2009). 2.4.2 Environmental measures Environmental Measures aim to reduce the concentration of TB droplet nuclei in the air and ways to control the direction of infectious air (WHO, 2009). It usually starts with construction of buildings, renovations and maintenance works. thereby reducing the risk of nosocomial TB infections that result from over-crowded wards in high-burden settings. Environmental measures could be natural or mechanical I artificial ventilation system. Simple natural ventilation is achieved by proper window sizes, and locating them on opposing walls (WHO, 2009). It is considered as a low maintenance, low cost and the most effective airborne infection control measure. As such, it is recommended in low-resourced settings in warm climates (Escombe et aI., 2007; Shenoi, Escombe, & Friedland, 2010). Mechanical ventilation in the form offans could also be employed when natural ventilation alone is not sufficient. Besides, ultraviolet germicidal irradiation (UVGI) fixtures may be used (WHO, 2009). The UGVI is climate independent, and as such addresses the limitation of natural ventilation (Shenoi et aI., 2010). However, it requires skilled architects for its proper installation (Nardell & Dharmadhikari, 2010). Environmental Measures is largely innuenced by resource availability making its effective implementation challenging in many low- resourced settings. However, proper staff training on the correct use of these measures and proper maintenance is shown to be beneficial. 2.4.3 Personal Respiratory Protection Measures Personal Protection Measures involves the use of personal protective equipment in instances .... hen there is increased risk of transmission (Jensen, Lambert, Iadermarco, & 16 University of Ghana http://ugspace.ug.edu.gh Ridzon, 2005). This may be in the fonn of particulate respirators or surgical masks. The respirators are recommended for health care workers directly involved in TB care as well as other facility users who encounter TB patients, while patients or people suspected to be infected with TB are advised to use surgical masks for proper coughing etiquettes. The WHO recommends particulate respirators that has standards equivalent to or exceeding N95 standard or FFP2 standard for US and Europe respectively (WHO, 2009). The personal protective measures complement HCWs level of protection after the administrative and environmental measures have been implemented. Constant provision of quality Personal Protective Equipment (PPE) coupled with adequate training for its use highly influences implementation ofTBIC measures. However, previous literature reports that tit-testing ofPPEs is neglected (Nardell & Dhannadhikari, 2010). 2.5 Healtb Care Workers' Knowledge and Practices towards tbe implementation ofTBIC Measures Health Care Workers (HCWs) playa very important role in the success or failure ofTBIC measures due to their frontline functions. An effective tuberculosis infection control will require that HeWs properly implement the various TBIC measures, and also educate TB patients and the community about basic control measures like adequate ventilation, cough h) giene. etc. As such, it is very necessary that they have adequate awareness and level of knowledge of the TBIC measures. A study in Northwest Ethiopia from August 2010 to January 20 II indicated that health professionals with good knowledge were ten (10) times more likely to practice TBIC compared to those with poor knowledge (Temesgen & Demissie, 2014). According to Demissie Gizaw. Aderaw Alemu, & Kibret (2015), tuberculosis training and work experiences are major contributory factors to knowledge, 17 University of Ghana http://ugspace.ug.edu.gh while TB related training and experiences are significant pointers to practice. A study in Russia showed that knowledge level of health care workers could influence the prevalence ofTB infection (Woith, Volchenkov, & Larson, 2012). Nonetheless, previous researchers have found that HCWs often lack adequate knowledge about TBIC. According to the study of selected health care workers in northwest Ethiopia by Temesgen and Demissie. "though the majority of the participants had good TBIC knowledge and practice, a considerable proportion of health professionals were not trained on TBIC" (Temesgen & Demissie, 2014). In 2013, a study by Minnery and his colleagues on the knowledge and attitudes offront-line TB personnel in Lima, Peru, also showed that there were major knowledge gaps in areas related to TB treatment and diagnosis, which retlected other previous findings in TB endemic areas throughout the world (Minnery et al..2013). Tuberculosis Infection Control (TBIC) involves employing diverse measures aimed at minimizing the risk of TB transmission within populations (WHO, 2009). The WHO recommended a combination of measures - including administrative measures, environmental measures, and personal respiratory protection - to reduce TB infection (WHO. 2009). Effective TBIC implementation requires early identification, isolation of infected persons, and timely, effective treatment of persons with TB. Gaps in the implementation of TBIC predispose health care workers and patients to nosocomial TB transmission (Temesgen & Demissie, 2014). However, TBIC is rarely effectively implemented in most developing countries due to resource constraints. A study of two districts in Uganda showed that TBIC measures were 18 University of Ghana http://ugspace.ug.edu.gh not being implemented. It identified factors like lack of staff, space and funds as barriers to the implementation of TBrC (Buregyeya, Mitchell, Rutebemberwa, Criel, & Kiguli, 2013). According to Temesgen and Demissie, '"a rapid assessment done in 2008 revealed that most health care facilities in Ethiopia do not use TBIC practices," exposing both health care workers and patients to TB transmission. especially at facilities with high case load (Temesgen & Demissie, 2014). Another research shows that a significant portion ofHCWs had unsatisfactory practice on TBIC (Demissie Gizaw et aI., 2015). 2.6 Facton Innuencing the Implementation ofTBIC Measures Tuberculosis. although a curable disease, remains a major health problem globally despite the various measures introduced by the World Health Organizations and other international bodies and groups (WHO, 2016). There are many challenges that many times beset the implementation of the tuberculosis infection control. These include clinical, institutional, and socio-cultural factors. Previous studies also identify other barriers such as delays in diagnosis, inadequate financial support, insufficient motivation. lack of clear guidelines, shortage of materials, inadequate qualified health professionals and inadequate health care worker training (Cramm, FinkenflUgel, M0l1er, & Nieboer, 20\0; Amo-Adjei, 20\3; Buregyeya et aI., 2013; Brouwer, Coelho, Das Dores Mosse, et aI., 2014; Wynne, Richter, Banura, & Kipp, 2014). Inadequac) of qualified health professionals coupled with poor training programs is a major hindrance to effective implementation ofTBIC. According to Wynne and colleagues (2014), health providers in Western Uganda are unable to effectively implement TB control 19 University of Ghana http://ugspace.ug.edu.gh programs due to inadequate qualified health professionals and poor health care worker training. There were health facilities that had only one health professional with proper training on TB, and other workers relied on outdated materials from school. The inadequacy of knowledge results in extensive delays in diagnosing patients, and in some cases. failure to even identify the signs and symptoms to screen the patients (Wynne et aI., 2014). Further, Buregyeya et al.. (2013) also identified lack of human resource (understaffing) as a limiting factor to effective implementation of TBIC. It was again reported that TBIC measures like screening for people with cough, timely sputum examination. and health education were perceived as extra workload for the already overstretched personnel (Tamir, Wasie, & Azage, 2016). As such, screening was not done at the point of arrival of the patients. In Mozambique, it was recorded that although some TB staff went through formal TB training. the auxiliary staff were not partaking in such trainings even though they often assisted with patient-related activities (Brouwer et aI., 2014). Other researchers showed that the practicality of some of the training programs also was inadequate. They revealed that training was not identified to have an influence on TBIC practice in many public health facilities in Ethiopia, indicating that it could be a result of much focus on the theoretical components of the training instead of the skill-based aspects (Temesgen & Demissie, 2014; Demissie Gizaw et aI., 2015). A study across 3 districts in South Africa revealed lack of training, poor compliance, absence of TBIC plan and committee, dire shortage of respirators as hindrances (Engelbrecht & Van Rensburg, 2013) . Also, implementation and practice of TBIC in facilities in Ikeja, Nigeria was poor due to barriers such as non-existence of TBIC plan. 20 University of Ghana http://ugspace.ug.edu.gh lack of training, shortage of manpower, stigmatization and structural inadequacies (Kuyinu et aI., 2016). In adequate funding for TB control programs is also a challenge to effective implementation of TBIC by health care workers. In Uganda, it was recorded that lack of adequate and consistent funding meant that health care workers were also limited in undertaking community visits and effective follow ups on patients. Logistics and medication were also inadequate and a significant portion of the financial burden was transferred to the patients, who mostly are unable to follow up with the routine (including the regular visits to health care facilities) drawn for dealing with the disease (Wynne et aI., 2014). These factors, amongst others, frustrated health professionals' ability to implement the DOTS program. Amo-Adjei (2013) indicated that inadequacy offunding coupled with delays in accessing funds from donors and the government was a barrier to effective TBIC implementation by some institutions in Ghana. Another barrier to effective implementation of TBIC is the lack of adherence of patients. Patients were identified as not complying with cough etiquette and separation process (Buregyeya et aI., 2013). A common pattern realized by Wynne et aI., (2014) was the attempts of patients to engage in self-treatments for initial cough symptoms till infection is worsened before a visit is made to hospitals. These factors contribute to extensive delays in diagnosis and overcrowding in health care facilities, thereby increasing the risk of transmission. Brouwer and Collegues also identified that patients' daily routine was also a challenge faced by HCWs to effective implementation of TBIC measures. There were certain measures some patients could not adhere to due to their everyday routines like 21 University of Ghana http://ugspace.ug.edu.gh eating meals together as a family, which made it difficult to separate infected persons from the family during these routines (Brouwer et aI., 2014). To add to the above, many researchers have identified flaws in the healthcare system as a challenge faced by health care workers in implementing TBIC measures. The study by Brouwer and colleagues (2014) revealed that in Mozambique, the healthcare system, including availability of necessary logistics and the infrastructure, was a main hindrance to the use ofTBIC measures both by HCWs and patients. There was also shortage of materials like boots, respirators, and other equipment, leading to indifference and poor attitude towards use of respirators. It also showed that there were inadequate spacing of consultation and waiting rooms, coupled with poor ventilation systems including defective windows and doors (Brouwer et aI., 2014). Also, according to Buregyeya et aI., (2013), health professionals in some districts in Uganda also cited lack of space in waiting area to en5ure that TB suspects are separated is a challenge. Wynne and colleagues in their study also identified other health system issues like "poor referral practices between health units" and absence of laboratory capacity to test for TB in many health facilities as a challenge (Wynne et aI., 2014). Health professionals were therefore unable to test or diagnose patients even when they suspect an infection. Further, low motivation ofHCWs due to low pa). lack of control over career development and inadequate work conditions, has been identified as a challenge to TBIC implementation (Brouwer et aI., 2014). 2.7 Measurement of Levels of Knowledge and Practice of HCWs on TBIC Generally, Health Care Workers' (HCWs) levels of knowledge and practices have been categorized into either good/adequate/proper or poor/improper in many studies. A cross- sectional study by Buregyeya and colleagues (2016) among HCWs in Uganda, used a cut- 22 University of Ghana http://ugspace.ug.edu.gh off of >70% to indicate "adequate" knowledge levels (Buregyeya, Kasasa, & Mitchell, 2016). Another study which assessed knowledge and practice of HCWs in Ethiopia, considered respondents with scores equal or above the mean as having "good knowledge/practice" and vice-versa (Demissie Gizaw et aI., 2015). In West Go.iiam Zone, Northwest Ethiopia, participants who scored SO% or more were considered to have had "proper TBIC practice levels" (Tamir et aI., 2016). Furthermore, another research used 2::60% for assessing "good knowledge" while for "good practice" 2::50% was used (Temesgen & Demissie, 2014). A South A frican study considered higher knowledge scores as suggestive of "greater knowledge" (Cramm et aI., 2010). Thus, in this study, the measure of knowledge will be scoring equal to or above the mean (7.S) for "good knowledge" and below the mean for "poor knowledge." The measure of practice will be ~ 5.9 for "good practice"' and < 5.9 for "poor practice." 2.8 Summary of Literature Review This chapler explored the relevant literature on implementation of tuberculosis infection control (TBIC) among health care workers. It recognized the various aspects of implementation ofTBIC among HCWs as stipulated by WHO in 2009, and identified the following levels of implementation of TBIC measures: Administrative and Managerial mea~urc~, Environmental Measures, and Personal Protection Measures. It also showed large gaps in training programs for HCWs, availability of TBIC materials (policy, guidelines, Information, Education and Communication materials, etc.) and PPEs, quality of environmental measures such as isolation rooms for TB patients, ventilation and infrastructural facilities. 23 University of Ghana http://ugspace.ug.edu.gh CHAPTER THREE METHODS 3.0 Introduction This chapter describes the methods employed for the study. It details the study design, study area, study population, variables and sampling procedure. It also covers data storage and protection, quality control, pre-testing of too Is, data analysis and ethical considerations. 3.1 Study Design The study was cross-sectional in design using mixed-methods to collect information on the implementation of Tuberculosis Infection Control (TBIC) among health care workers at the Greater Accra Regional Hospital. The use of quantitative and qualitative methods provide broad and in-depth understanding of the phenomenon being studied (Johnson, Onwuegbuzie, & Turner, 2007). The mixed-method approach involved structured intervie .... s, direct observation and Key Informant Interviews (Klls). This was to enhance accuracy and triangulate information received from the participants. 3.2 Study Area The study was conducted at the Greater Accra Regional Hospital in the Accra Metropolitan Assembly area in the Greater Accra Region. Greater Accra Region is one of the ten administrative regions of Ghana. It was reported to be the region with the second highest TB incidence of about 2,901 in 2014 (NTP, 2014, unpublished data). Accra Metropolitan Assembly (AMA) is divided into six sub metros namely Osu Klottey, Kpeshie, Okaikoi, Asheidu Keteke, Ablekuma and Ayawaso. The population peaks at age group 20- 24 (12.4% of the entire popUlation) followed by age group 25-29 (11.5% of the 24 University of Ghana http://ugspace.ug.edu.gh entire population). A greater proportion (89%) of the AMA population aged 11 years and older are literates (Ghana Statistical Service, 2014). Accra Metropolitan has 218 health facilities consisting of 28 hospitals, 130 health centers and 60 other fonns of health post One hundred and eighty seven (187) of these health facilities are owned by private and non-governmental organizations. The main health problem of Accra metropolitan is infectious disease especially malaria and cholera due to poor sanitation and poverty (Ghana Statistical Service, 2014). The Greater Accra Regional Hospital was fonnally known as Ridge Regional Hospital with about 19 I-bed capacity. After the current renovation, the facility was equipped to a 600- bed capacity. The Greater Accra Regional Hospital is one of four government hospitals in the metropolis and provides medical care ranging from general medicine to specialized medical care. The total medical staff strength of the facility is about 736. The hospital has a separate laboratory for TB testing with an average monthly acid fast bacilli request of79. The facility also has a DOT center responsible for dispensing TB drugs, monitoring and recording treatment progress of TB patients. Some staff at the DOT center are recruited and trained by the National Tuberculosis Program (NTP) in Ghana. 25 University of Ghana http://ugspace.ug.edu.gh ~ w.. .. .. ~ -:-~.

Therefore using the sample size formula by Yamane 1967, N no = 1 + N(e)2 .................................. (1) where: n: sample size N: the population size of the HCW s, 20 I e: precision, 5% (0.05) Inputting the above into equation (I), the minimum sample size of Health Care Workers required for this study was given by: 201 no = 1+201(0.05)2 = 133.8 ~ 134 Therefore, the minimum sample size for Health Care Workers was 134. 3.5.2 Sampling Procedure A complete survey "as done to obtain the number and cadre of Health Care Workers (HCWs) in the various units of interest. The units: DOTS Center, ART, Medical, OPD, Triage, Paediatrics and Pharmacy, were selected using simple random sampling technique. Data collection started from 22nd May to 28th June, 2017. The proportion of Health Care 31 University of Ghana http://ugspace.ug.edu.gh Workers selected from each category was based on the number of staff (n=20 I) present at the various units within the study period: nurses (n=73), Doctors (n=78), Pharmacists (n=15) and Allied Health Professionals (n=35). The constant proportion of 0.667 [134120 I = 0.667] was multiplied by the number of persons in each job category to obtain the expected sample size for each category. Finally, the sample size for each category was used to obtain the percentage of persons that was selected. The Table below shows the sample size for each of the job categories in the study. Table 3.2: HCWs Distribution from Each Job Category Job Category Total Constant Sample Size Percent (%) from Number Proportion Required Each Group Doctors 73 0.667 49 36.57 Nurses 78 0.667 52 38.81 Pharmacy Personnel 15 0.667 10 7.45 Allied Health Professionals 35 0.667 23 17.16 Total 201 134 100 The sample size (134) was apportioned to each selected unit based on the size of health care workers at post during the period of data collection. Stratification of the HeWs was done according to their job category. The sampling frame (list of health care workers by job category) for each stratum was obtained from the units and a simple random sampling method applied to recruit them. The random numbers were computer generated using 32 University of Ghana http://ugspace.ug.edu.gh Microsoft Excel. The aim was to ensure that every Health Care Worker had an equal chance of being selected. 3.5.3 Data Collection Instruments The Health Care Workers (HCWs) were made to read and sign the consent forms (Appendix I) given to them before they were administered the questionnaire (Appendix II). Concerns and questions regarding the study were also addressed. A semi-structured questionnaire adapted from Codjoe (2012) was modified according to the WHO guideline for reducing TB transmission in healthcare settings (WHO, 2009). The questionnaire was in four (4) sections. Section one (I) covered the socio-demographic information and work- related demographics of the HCWs (age, gender, marital status, educational status, job category, professional working years, years worked in facility, current unit of work, training on TBIC and presence of any known medical condition). Section two (2) assessed the level of knowledge and practices of the Health Care Workers on TB and TB Infection Control (Mode of TB spread, classical signs/symptoms of TB, Persons with high risk of TB exposure and infection, cough etiquette, persons with greatest risk of TB spread in healthcare settings, use of PPEs, ways of identifying TB suspects etc). Section three (3) explored service factors influencing TBIC at the facility (availability of TBIC materials, availability of separate laboratory for TB testing and reporting, screening of TB patients and Staff, isolation of infectious patients and availability of intervention packages for HCWs). Section four (4) examined the environmental factors influencing TB infection control (size of waiting area, crowding, ventilation and availability of well-ventilated sputum booth). The questions on knowledge and practice were assessed using 10 and II responses respectively. "Yes" or "No" were scored as "I" and "0" respectively. Knowledge 33 University of Ghana http://ugspace.ug.edu.gh or Practice scores above the mean score were considered as "good" while those below the mean were considered "poor" (Demissie Gizaw et aI., 2015). 3.5.4 Key Informant Interviews Purposive sampling using maximum variation technique was employed to recruit seven (7) key individuals responsible for effective implementation of TBIC at the Greater Accra Regional Hospital. Purposive sampling technique is ''used in qualitative research for the identification and selection of infonnation rich cases related to the phenomenon of interest" (Palinkas et aI., 2015). Seven (7) key infonnants comprising of the Medical Director, Hospital Administrator. Accountant. Greater Accra Regional Physician in charge of TB care, Infection Prevention Control (IPC) focal person, DOTS Center In-charge and Head of TB Bacteriology Laboratory were purposively selected. A Key Infonnant Interview (KII) guide adopted from Adeleke (2012), and modified in accordance with the WHO Tuberculosis Infection Control guideline was used for the interviews. The infonnation obtained was used to triangulate infonnation provided by the HCWs and direct observation. The Key Infonnants Interviews (KIIs) lasted between 10-60 minutes and recorded using an audio recorder. Notes were also taken to ensure accuracy. The KIIs were carried out at the offices of the participants to ensure privacy. 3.5.5 Direct Observation of Health Care Workers' Practice Health care workers were observed directly during their routine work to assess how they carried out TB infection control. An observation grid outlining observable measures of administrative, environment and personal protection was used. The researcher spent five (5) working days observing daily TBIC practices. This approach infonned on additional questions to include in semi-structured interviews and complemented the results thereof. 34 University of Ghana http://ugspace.ug.edu.gh 3.6 Quality Control 3.6.1 Data Handling Data collection tools were pre-tested at the University of Ghana Hospital prior to data collection. Research Assistants were trained to accurately carry out the data collection. The study materials were well explained to the HeWs prior to interview. • Questionnaires and field notes were cross-checked by principal researcher. 3.6.2 Data Storage I Data Protection All the questionnaires, checklists and transcripts were kept under lock and key in a cabinet. A soft copy of data collected were coded and locked on a computer using a password and only accessible to the principal researcher and others involved in the research work. 3.6.3 Data Validation Research assistants were trained on appropriate data collection skills to ensure uniformity of data collected. Data collected daily on the field were checked and cleaned manually for completeness, clarity and consistency. 3.6.4 Pre-testing of Tools The data collection tools were pre-tested at the University of Ghana Hospital using 20 participants before the commencement of the study. The pre-testing helped to clarify the data collection tools and to ensure research adequacy and freedom from bias. It also unearthed ambiguity in the questions thereby enabling rephrasing of such questions, and ensured a logical flow of the items on the questionnaire. Further, it enabled the research team to ha\'e a better appreciation of the data collection process. 35 University of Ghana http://ugspace.ug.edu.gh 3.7 Data Analysis Quantitative data collected were entered into REDcap and Ex.cel and then transferred into STATA 14.0 for cleaning, merging and analysis. Data were cleaned by running the frequencies of the variables to check for any form of inconsistencies. The inconsistent data were then checked with the raw data from the questionnaire. Knowledge and practice scores were computed for all correct responses to the questions. There were 10 responses for assessing level of knowledge and 11 responses for assessing HCWs practice on TBIC. Scores equal to or above the mean (7.8 for knowledge level, and 5.9 for practice level) were termed "good" while those below the mean were considered "poor." Data were presented using frequency tables and charts where necessary. Mean and standard deviations were computed for continuous variables and proportions for categorical variables. Chi-square was used to determine the association between level of knowledge and practice, and demographic characteristics and Fisher's ex.act test was used when sample size was small. Cramers V was used to determine the strength of the association between level of knowledge and practice and demographic characteristics. Logistic regression was then used to determine the Odds Ratio for the independent variables, which were statistically significant. Significance was set at p<0.05. Qualitative data was analyzed manually. Thematic content analysis was used to analyze the transcribed data from key informant interviews and non-participant observation. Transcripts were read several times to get an overall picture of the contents and meaningful ideas coded, condensed and categorized into broader themes (Graneheim & Lundman, 2004), such as availability of TBle materials, adequacy of ventilation at the facility, training of HCWs on TBIC, screening of HCWs and patients. Data were then interpreted 36 University of Ghana http://ugspace.ug.edu.gh using insights, intuition and literature and presented in texts, verbal quotation. The qualitative rmding were used to triangulate the infonnation received from the HCWs and the direct observation. 3.8 Limitations I. At the time of the study, the hospital was in a state of transition from its old building into a newly built ultra-modem facility. As such, responses were mixed reflecting the situation of both the old and new structures and facilities of the hospital. 2. The study explored educational status of the Health Care Workers based on primary, secondary and tertiary educational level which resulted a skewed response toward tertiary education. As such, no variation was found during data analysis, leading to the exclusion of educational status from the logistic regression model. 3. The use of a cross-sectional study. Cross sectional study design is a snapshot and responses can vary if measured at different times. 3.9 Ethicatlssues This study obtained ethical clearance from Ghana Health Service Ethical Review Committee (GHS-ERC). A written infonned consent was obtained from the participants before they were recruited in the study. Pennission was also sought from the head of the Greater Accra Regional Hospital before the study commenced. 3.9.1 Privacy and Confidentiality Interviews were done in a manner to ensure privacy and confidentiality. Each participant "as assigned a code to avoid using names and ensure anonymity. The infonnation collected from the interviews was treated confidential and available only to the researcher and other 37 University of Ghana http://ugspace.ug.edu.gh custodians of the research. Hard copy of questionnaires was kept under lock and key in a box while soft copy of data was password protected on a laptop. The data will then be destroyed after five years. 3.9.2 Voluntary Participation and Withdrawal The objectives and procedures of the study were well explained to the participants and they were made aware that they were free to participate or withdraw from the research any time without any negative effect. 3.9.3 Benefits There was no direct monetary benefit in this study. However, participants were given souvenirs and also got the opportunity to add on to knowledge in the area ofTB infection control and its effective implementation for societal benefit. 3.9.4 Cost/Compensation Participants did not incur any cost in this study. The study did not also provide compensation in the form of money to the participants. 3.9.5 Declaration of Con nict ofinterest The researcher had no potential conflict of interest with respect to the study. 3.9.6 Research Funding This research was funded by the NIH Fogarty International Centre through partnership with the University of Ghana, College of Health Sciences and the University of Florida. 38 University of Ghana http://ugspace.ug.edu.gh CHAPTER FOUR RESULTS 4.0 Introduction This chapter details the findings of this study in line with the set objectives. It is in four sections. Section one shows socio-demographic and work-related characteristics of participants. Section two presents the knowledge and practice of Health Care Workers on TB and TB Infection Control. Sections three and four present the service and environmental factors influencing the implementation ofTB infection control (TBIC). 4.1 Socia-Demographic Cbaracteristics of Participants A total number of 137 Health Care Workers (HCWs) participated in the study. Majority, 62 (45.3%) ofthe Health Care Workers were between the ages 18 to 29 years, and the mean age was 32.5 years (SD = 7.6). Almost two-thirds, 85 (62.0%) of the participants were females, and more than half, 76 (55.5%) were married (Table 4.1a). In terms of educational status, almost all, 136 (99.3%) of the participants had tertiary education. Also, 123 (89.8%) of the participants indicated that they had no medical condition, and none of the medical conditions indicated was tuberculosis. 39 University of Ghana http://ugspace.ug.edu.gh Table 4.la: Socio-Demographic Characteristics of Health Care Workers (HCWs) Characteristics Number(n 137) Percent(%) Age (years)* 18 to 29 years 62 45.3 30 to 39 years 56 40.9 40 to 49 years 9 6.6 50 years and above 10 7.3 Gender Male 52 38.0 Female 85 62.0 Marital Status Single 60 43.8 Married 76 55.5 Separated/Divorced 0.7 Educational Status Secondary 0.7 Tertiary 136 99.3 Presence of medical condition No 123 89.8 Yes 14 10.2 Medical condition" Allergic Rhinitis 2 16.7 Asthma 2 16.7 Back pain 2 16.7 Coccyx pain 8.3 Hypertension 4 33.3 Polycystic Ovarian Syndrome (PCOS) 1 8.3 -Mean Age of HCWs = (32.5 ± 7.6) years, Min.

However, two participants did not indicate the medical condition. 40 University of Ghana http://ugspace.ug.edu.gh A similar proportion of the participants were doctors, 50 (36.5%) or nurses, 52 (38.0%), and 25 (18.3%) being Allied Health professionals. More than half, 70 (51.1 %) of them had a total professional working years of less than five years. Additionally, 87 (63.5%) had worked in the study facility between one and five years. Further, 30 (21.9%) of the participants were from the medical unit. The OOTS and ART units which were directly involved in TB care had nine participants in this study (Table 4.lb). More than one-third, 53 (38.7%) of the participants reported that they had received some fonn of training on TB infection control in the facility. Of these, 29 (54.7%) were trained within the past year while 24 (45.3%) were trained over a year ago (Table 4.lb). 41 University of Ghana http://ugspace.ug.edu.gh Table 4.1b: Work-related Demographics of Health Care Workers Characteristics Number~n!

More than two-thirds, 5 (71.4%) of the participants had their Master's Degree. The number of years the participants had worked in the facility ranged from 2 to 18 years with a mean of 7.8 years working experience and these were mainly managers of the units. 4.2 Level of Knowledge of HCWs 00 TB and TBIC The overall level ofknowledge was good in this study (Table 4.2), with 88 (64.2%) of the participants scoring equal or above the mean (7.8 ± 1.5). Almost all, 131 (95.6%) of the participants correctly identified "airborne" as the mode of TB spread, and 124 (90.5%) recognized people who are immune-compromised such as HIV/AIDS patients as individuals with high risk ofTB exposure and infection. 43 University of Ghana http://ugspace.ug.edu.gh Table 4.2: Knowledge of Healtb Care Workers on TB and TBIC Number Percent Characteristics (n) (%) Mode of TB spread Airborne 131 95.6 Through blood or physical contact 6 4.4 Persons with higher risk ofTB exposure and infection Persons who are Immuno-compromised.

More than two-thirds, 97 (70.8%) identified undiagnosed coughing patients as potential risk groups for TB spread in Healthcare settings. For cough etiquette, 86 (62.8%) admitted that cough etiquette is required of all persons at all times. Additionally, 120 (87.6%) of the HeWs recognized the use of natural ventilation (doors, windows) and maximizing cross-ventilation as the best and cheapest way to reduce TB bacilli in the air (Table 4.2). 4.3 Relationship between Level of Knowledge and Demographic Characteristics of HCWs Table 4.3 shows the relationship between level of knowledge and demographic characteristics of the HCWs. Gender, marital status and current unit of work were the variables that exhibited a statistically significant relationship with level of knowledge. Majority, 60 (70.6%) of the females had good knowledge relative to 28 (53.9%) of the males with good knowledge (V= 0.17, P = 0.047). A significantly higher proportion of the Hews who were married, 55 (72.4%) recorded high level of good knowledge compared with the HeWs who were single, 32 (53.3%), [V= 0.21, P = 0.036]. The unit in which a health worker worked in the hospital determined the level of knowledge. Thus, it was not surprising that all of the HeWs directly involved in TB care (DOTS and ART) recorded "good knowledge" ofTB and TBIC, while 8 (80.0%) of the Pharmacy and 23 (76.7%) of the Medical unit HeWs also displayed good knowledge. However, majority, 7 (70.0%) of thl: laboratory HeWs and 9 (56.3%) of the dental unit HeWs recorded poor knowledge. 4S University of Ghana http://ugspace.ug.edu.gh The difference in knowledge ofTB and TBIC by unit was statistically significant (V=O.36, p=O.OIS). Age, educational status, job category, professional working years, years worked in the facility and training received on TBIC did not show any significant statistical relationship with knowledge ofTB and TBIC. All adults between 40 to 49 years had good knowledge. Further, 39 (62.9%) of HCWs aged 18 to 29 years, and 35 (62.5%) of HeWs aged 30 to 39 years also had good knowledge (Table 4.3). 46 University of Ghana http://ugspace.ug.edu.gh Table 4.3: Relationship between Level of Knowledge and Demographic Characteristics of HCWs Knowledge level Good Poor Cramers Characteristics Cat!:,Bo!I KnowledGe KnowledGe V P-Value Gender Male 28 (53.9) 24(46.2) 0.170 0.047· Female 60 (70.6) 25 (29.4) Age Category 18 to 29 years 39 (62.9) 23 (37.1) 0.210 0.082 30 to 39 years 35 (62.5) 21 (37.5) 40 to 49 years 9 (100.0) 0(0.0) 50 years and above 5 (50.0) 5 (50.0) Marital Status Single 32 (53.3) 28 (46.7) 0.207 0.036· Married 55 (72.4) 21 (27.6) SeparatedlDivorced 1(100.0) 0(0.0) Educational Status Secondary I (100.0) 0(0.0) -0.064 0.642 Tertiary 87 (64.0) 49(36.1) Job Category Nurse 31 (59.6) 21 (40.4) 0.181 0.217 Doctor 36 (72.0) 14 (28.0) Phannacist 8 (80.0) 2 (20.0) Allied Health Professional 13 (52.0) 12 (48.0) Professional Working Years Less than 5 years 47 (67.1) 23 (32.9) 0.194 0.267 >=5 to <10 years 23 (54.8) 19 (45.2) >=10 to <15 years 11 (84.6) 2 (15.4) >= 15 to <20 years 3 (75.0) 1 (25.0) 20 years and above 4 (50.0) 4 (50.0) Facility Working Years Less than I year 4 (57.1) 3 (42.9) 0.152 0.760 >= 1 to <5 years 55 (63.2) 32 (36.8) >=5 to < 10 years 22 (66.7) II (33.3) >=10 to <15 years 4 (80.0) 1(20.0) >= 15 to <20 years 2 (100.0) 0(0.0) 20 years and above 1(33.3) 2 (66.7) Current Unit of Work DOTS and ART 9 (100.0) 0(0.0) 0.360 Medical 0.018· 23 (76.7) 7 (23.3) Surgical 8 (72.7) 3 (27.3) OPD& Triage 3 (50.0) 3 (50.0) Phannacy 8 (80.0) 2 (20.0) Dental 7 (43.8) 9 (56.3) Paediatrics 16(64.0) 9(36.0) Laboratory 3 (30.0) 7 (70.0) Other II (55.0) Received Training on 9 (45.0) TBIC Yes 3 (64.2) 30 (35.7) No 0.0014 0.987 * 54(64.3) Significant at p<0.05 19(35.9) 47 University of Ghana http://ugspace.ug.edu.gh Generally, the majority of all job categories had good knowledge scores, with Pharmacist (80.0%) and Doctors (72.0%) recording the highest. Likewise, the majority ofa ll categories for professional working years and years worked in the facility of study had good knowledge scores (Table 4.3). In terms of training on TBIC, there was no significant variation of the knowledge level between the participants who have received training (64.2% good knowledge level), and those who have not received training (64.3% good knowledge). 4.4 Health Care Worker Factors Associated with Level of TB and TBIC Knowledge From Table 4.4, females had 2.06 times the odds of good knowledge compared to the males and this was significant (95% CI 1.00-4.22). The odds of the good knowledge increased to 2.80 after adjusting for age, marital status,job category, current unit of work, years worked in facility and training on TBIC (95% CI 0.98-7.97). The Health Care Workers between the ages of 30 to 39 years had 2% reduced odds of good knowledge compared to those who were aged 18 to 29 years (95% CI 0.47-2.07). The participants who were married were 2.29 times more likely to have good knowledge compared to those who were single (95% CI 1.12-4.68). However, multivariate logistic regression models that included variables for gender. age, job category, current unit of work, years worked in facility and training on TBIC revealed that marital status is the strongest determinant of knowledge, AOR 3.19 and 95% CI (1.11-9.13). 48 University of Ghana http://ugspace.ug.edu.gh Table 4.4: Odds Ratio ofSoeio-demograpbic and Work-related Factors Associated witb Level of Knowledge of Healtb Care Workers on TO and TOIC Cha racteristics Category COR (9S% CI) AOR(95%CI) Gender Male Ref Ref Female 2.06 (1.00-4.22)· 2.80 (0.98-7.97) Age Category 18 to 29 years Ref Ref 30 to 39 years 0.98 (0.47-2.07) 0.98 (0.30-3.17) 40 to 49 years I I 50 years and above 0.59 (0.15-2.26) 0.39 (0.04-4.09) Marital Status Single Ref Ref Married 2.29 ( 1.12-4.68). 3.19 (1.11-9.13)· SeparatedlDivorced I I Job Category Nurse Ref Ref Doctor 1.74 (0.76-3.99) 2.98 (0.78-11.43) Pharmacist 2.71 (0.52-14.05) 0.92 (0.08-10.75) Allied Health Professional 0.73 (0.28-1.92) 1.39 (0.20-9.80) Current Unit OOTS and ART Ref Ref Medical 2.69 (0.79-9.12) 1.61 (0.27-9.55) Surgical 2.18 (0.44-10.73) 1.04 (0.10-11.02) OPD& Triage 0.82 (0.13-5.08) 0.56 (0.06-5.50) Phannacy 3.27 (0.55-19.45) I Dental 0.64 (0.17-2.39) 0.32 (0.06-1.88) Paediatrics 1.45 (0.44-4.84) 0.62 (0.11-3.66) Laboratory 0.35 (0.07-1.76) 0.27 (0.03-2.15) Other I 1 Years worked in facility Less than I year Ref Ref >= I to <5 years 1.29 (0.27-6.13) 1.84 (0.26-12.84) >= 5 to <10 years 1.50 (0.28-7.91) 1.79 (0.19-17.31) >=\0 to <15 years 3.00 (0.21-42.62) 1.82 (0.07-46.88) >= 15 to <20 years I I 20 years and above 0.38 (0.02-6.35) 1.39 (0.03-66.74) Received Training on TBIC No Ref Ref Yes *Significant association, p<0.05 0.99 (0.49-2.04) 0.54 (0.21-1.43) COR Crude Odds Ratio AOR-Adjusted Odds Ratio 49 University of Ghana http://ugspace.ug.edu.gh Participants who were doctors had an increased odds of good knowledge compared to nurses [COR=1.74, 95% CI (0.76-3.99)]. After adjusting for gender, age, marital status, current unit of work, years worked in facility and training on TBIC, the odds of good knowledge increased to 2.98 (95% CI 0.78-11.43). Pharmacists also recorded 2.71 times the odds of good knowledge compared to the nurses (95% CI 0.52-14.05). However, the odds of good knowledge reduced by 8% after adjusting for the other variables (95% CI 0.08-10.75). The Health Care Workers at the medical and surgical unit had increased odds of good knowledge [COR= 2.69 (95% CI 0.79-9.12)] and [COR= 2.18 (95% CI 0.44-10.73)] respectively although not significant (p>0.05). On the other hand, AOR were 1.61 (95% CI 0.27-9.55) and 1.04 (95% CI 0.10-11.02) respectively in the multivariate models. Years worked in facility and training on TBIC did not show any significant association with TBIC knowledge (Table 4.4). One of the KIIs indicated that, ., '" One sad Ihing is Ihal, when we even organize Ihe workshop for Ihem, lhe Iraining, Ihey will regisler, and they will not sit 10 enjoy the learning and leaching process that will go on.

(KII-04, GARH). 4.5 Level of Practice of Health Care Workers (HCWs) of TB Infection Control From Table 4.5, the overall level of practice of the Health Care Workers was good, with 83 (60.6%) scoring equal to or above the mean (5.9 ± 1.5). The minimum SCore was 2 \\'hile so University of Ghana http://ugspace.ug.edu.gh the maximum score 9. Most, 119 (86.91'10) of the HCWs mentioned that they use chronic cough for> 2 weeks as a means of identifying TB suspects. However, only 17 (12.4%) use presence of fever to identify the suspects. Majority, 125 (91.2%) of health workers interviewed reported that they screened people suspected ofTB while 100 (73.0%) of them separated TB patients from other patients. Fast tracking of smear positive cases to minimize stay in hospital and education of patients on cough etiquette were minimally practiced by the HCWs. Thirty-seven (27.0%) of health workers practiced fast tracking of smear positive cases while 33 (24.1 %) practiced education of patients on cough etiquette. More than half, 73 (53.3%) of the health workers provided nose masks to coughing patients while 113 (82.5%) of them reported that they use personal protective equipment when working with high risk individuals (Table 4.5). 51 University of Ghana http://ugspace.ug.edu.gh Table 4.5: Practice of HCWs regarding TB Infection Control at the Greater Accra Regional Hospital Number Percent Cbaracteristics (n=137) ('Yo) Promptly Identify TO suspects using signs/symptoms Chronic cough> 2 weeks Yes 119 86.9 No 18 13.1 Coughing out blood Yes 46 33.6 No 91 66.4 Weight Loss Yes 81 59.1 No 56 40.9 Night Sweats Yes 53 38.7 No 84 61.3 Fever Yes 17 12.4 No 120 87.6 Screening of suspected TO patients Screen TB suspects 125 91.2 Do not screen TB suspects 12 8.8 Separation of TO Patients Separate TB patients 100 73.0 Do not separate TB patients 37 27.0 Fast track smear positive cases to minimize stay in facility Yes 37 27.0 No 100 73.0 Educate cougbing patients on cough etiquette Yes 33 No 24.1 104 75.9 Pro\lide nose mask or tissue to coughing patients Yes No 73 53.3 64 46.7 Use of Personal Protecti\le Equipment Yes No 113 82.5 24 17.5 O\lerall Practice Le\lel Good Practice Poor Practice 83 60.6 54 39.4 S2 University of Ghana http://ugspace.ug.edu.gh 4.6 Relationship between Level of Practice and Demographic characteristics of Health Care Workers Tables 4.6a and 4.6b present the relationship between the level of practice of the HCWs on TBIC and their demographic characteristics. Job category, professional working years, current unit of work and level of knowledge were significantly associated with the level of practice of HCWs in implementing TBIC. Majority, 42 (84.0%) of the doctors exhibited good practice while 8 (32.0%) of the Allied Health Professionals recorded good practice (V= 0.40, p=5 to <10 years 20 (47.6) 22 (52.4) >=10 to <15 years 4 (30.8) 9 (69.2) >= 15 to <20 years 2 (50.0) 2 (50.0) 20 years and ahove 7 (87.5) 1 (12.5) Facility Working Years Less than I year 5 (71.4) 2 (28.6) 0.146 0.805 >=1 to <5 years 54 (62.1) 33 (37.9) >=5 to < 10 years 17 (51.5) 16 (48.5) >=10 to <15 years 3 (60.0) 2 (40.0) >= 15 to <20 years 2 (100.0) 0(0.0) 20 years and above 2 (66.7) I (33.3) *Significant at p; 5 to <10 years 0.36 (0.16-O.8W 0.95 (0.26-3.39) >= IOto<15years O.IS (0.05-0.64)* 0.15 (0.02-1.1 0) >= 15 to <20 years 0.40 (0.05-3.04) 1.22 (0.07-21.45) 20 years and above 2.80 (0.32-24.24) 15.51 (0.SS-272.70) Recei\'ed Training on TOIC No Ref Ref Yes 0.99 (0.49-1.99) 1.60 (0.54-4.75) Level of Knowledge Poor Knowledge Ref Ref Good Knowfedse 4.21 {2.01-S.84~* 5.83 (2.07-f6.43~. *Significant association at p<0.05 COR= Crude Odds Ratio AOR-Adjusted Odds Ratio 59 University of Ghana http://ugspace.ug.edu.gh 4.8 Service Factors Influencing Implementation of TBIC at tbe Greater Accra Regional Hospital Table 4.8 explored the service factors influencing TB infection control at the Greater Accra Regional Hospital. Generally, the Health Care Workers perceived screening of patients, availability of separate TB laboratory and availability of personal protective equipment as the service factors promoting sustained implementation of TBIC at the Greater Accra Regional Hospital. However, inadequate TBIC materials, lack of an isolation ward and the absence of staff screening were perceived as factors inhibiting sustained implementation ofTB infection Control in the facility. Availability of TBIC policy at the health facility was reported by 67 (48.9%) of the participants. However, 56 (40.9%) of them did not know of the availability of such policy. Most of the participants in the Key Informant Interviews (KlIs) also indicated the absence ofa TBIC policy in the facility: ., There is one for Infection, Prevention and Control. I think it was launched around 201312015, when the Ebola scare came. So IPC came all on the agenda, so there was a national policy ... we don 'I have a separate one for TB. Because we are part oft he Ghana Health Service facilities, we all join what the headquarters produces. So they produce the guidelines and al/ facilities are supposed to adhere to i/. .. (KII-03, GARH) "No [we don't have a structured TBIC policy in the facility] we are using the National TB Control Programme policies; and the Ghana Health 60 University of Ghana http://ugspace.ug.edu.gh Service (GHS) has policies on management ofi nfectious diseases. So those two are integrated in managing TR." (KJl-07, GARH) "For thisfacility, No, we are all using the national guideline. So that's what we use . .. (KII-04, GARH) A copy of the National Infection Prevention Control Policy was sighted during the direct observation process. With reference to the existence of a TBIC committee or focal person in charge of TB infection control, more than half, 93 (67.1)010) of the HCWs specified that there was a TBlC committee or focal person in the facility (Table 4.8). The Klls also indicated the existence of a TBIC committee or focal person in the facility for sustained TB Infection control. "Yes, we have fa TRte committee or focal person). We have our Quality Assurance Team ... there are other members who constitute the committee. t was part of it. It is not limited to only TR, It is for all other infections in the facility ... "(KII-04, GARH). "Rather, we have a permanent team headed by a TB focal person/coordinator, and we also have another coordinator for ART. The two work together because TB has a link with HIV, so the two collaborate. And they also work closely with our laboratory, because oft he sputum tests, and some other aspects of TB necessary for confirmation from the sputum, 61 University of Ghana http://ugspace.ug.edu.gh elc. So, Ihese 3 unilS work together, with supportfrom management. .. (KII- 06,GARH). The existence ofstaffTB screening mechanism for HCWs was reported as being absent by 105 (76.6%) of the participants as there was no system in place for periodic staff screening for TB. The participants in the KlIs on the other hand, held divergent views about staff screening for TB in the hospital: "/ am not sure ift here is a programme to screen staff; we haven't budgeted for that, which / am aware ofa s ofn ow. .. (KII-02, GARH) ··/1 is available but people do not patronize" (KII-03, GARH) " ... They {the staff] are not interested, yet we have told them.

Last year I heard one of the staff contracted TB or something like that. .. (KII-07, GARH). Concerning special interventions for HCW s who might be infected with TB on the job, 51 (37.2%) responded that there was no such special intervention. Further, more than half, 81 62 University of Ghana http://ugspace.ug.edu.gh (59.1%) of the HeWs stated that they were not aware if the facility had any such intervention package for staff(Table 4.8). Responses from the KIIs also affirmed that there was no special intervention for HeWs who might be infected with TB while on the job: "Not a special {intervention] as such, but we have made arrangements for every stajJto be on insurance. Secondly, by a collective agreement, we are to meet 50% ofc osts that are not covered by the National Health Insurance Scheme.

(KII-04, GARH) Regarding the availability of an isolation ward for separation of infectious TB patients, almost half, 66 (48.2%) of the HeWs indicated the absence of an isolation ward in the facility, while 30 (22.9%) stated that they know of any isolation ward in the facility. The KIIs also reported the absence of an isolation ward in the old health facility: 63 University of Ghana http://ugspace.ug.edu.gh "The problem is that we don't have afunctioning Isolation Ward currently; only the verandas are used That is a minus, because they are supposed to be cared for in an isolation ward Therefore, that is a something we don't have which we have tofactor into our plans." (KII-OI, GARH) ..... For our new facility ... we have now separated TB cases from the new facility because the whole place is air-conditioned, even though there are some isolation wards in there. So we have separate wards for TB cases now . .. (KII-03, GARH) Sixty-six (48.2%) of the participants reported that the hospital had a separate laboratory for TB testing and reporting while 38 (27.7%) indicated that they were not aware ofa separate TB laboratory in the facility. Direct-observation also revealed the existence of a separate laboratory for TB testing and reporting. 64 University of Ghana http://ugspace.ug.edu.gh Table 4.8: Sen-ice Factors Influencing Implementation ofTBIC at tbe Greater Accra Regional Hospital Service Factors Number (n=137) Percent (%) Availability ofTBIC Policy Presence ofTBIC Policy 67 48.9 Absence ofTBIC Policy 14 10.2 Don't know 56 40.9 Existence of a TBIC Committee or Focal Person Existence ofa TBIC Committee 93 67.9 Absence of a TBIC Committee 5 3.7 Don't know 39 28.5 Screening of StatT for T8 Presence of staff screening 29 21.2 Absence of statT screening 105 76.6 Don't know 3 2.2 Availability of Special Intervention for HCWs Special Intervention present 3.7 No special Intervention 51 37.2 Don't know 81 59.1 Availability ora Separate TB Lab Presence of a separate lab 66 48.2 No separated lab 33 24.1 Don't know 38 27.7 Availability ofTB Isolation Ward Presence of an isolation ward 41 31.3 No isolation ward 66 48.2 Don't know 30 22.9 65 University of Ghana http://ugspace.ug.edu.gh 4.9 Environmental Factors InOuencing TB Infection Control at the Greater Accra Regional Hospital Table 4.9 explored the environmental factors influencing the implementation of TB infection Control in the facility. Generally, there was no environmental factor perceived as promoting sustained implementation of TBIC in the facility. However, the HCWs perceived small waiting area, poor ventilation and absence of a well-ventilated sputum booth for safe sputum production and disposal as inhibitors to sustained implementation of TBIC in the facility. More than half, 77 (56.2%) of the participants indicated that the size of the patients waiting areas were too small to accommodate patients without crowding, while majority, 104 (75.9%) reported that they sometimes experience crowding at the waiting areas. Respondents in the KlIs had this to say: .. The space [waiting area] was not adequate, especially with the old place. Now, we can say that there has been an improvement. But with the cu"ent tight environment with a centralized air-conditioning, I am not sure it is good/or TB infection control." (KII-Ol, GARH) "Taking the OPD setting/or example, the place is overcrowded; there is no proper ventilation. " (KII-04, GARH) "Our concern was the way the OPD down there was closed in.

(KII-03, GARH) Direct observation at some of the units showed presence of crowding at the patient waiting areas. The predominant ventilation type reported by participants was mixed ventilation (use of both natural and mechanical ventilation). Responses from the KIIs indicated that the facility used either natural, mechanical or mixed ventilation: ..... We have windows; we open the windows. When dealing with TB. we do not use the fans; we use natural ventilation. .. (KII-06, GARH) "For our new facility. it is mainly air-conditioned. .. ..

This chapter presents an in depth discussion ofthe study findings in line with the following specific objectives: Level of knowledge and Practice of Health Care Workers on TB Infection Control; Service Factors Influencing Sustained Implementation of TB Infection Control and Environmental Factors Influencing Sustained Implementation ofTB Infection Control. 5.1 Level of Knowledge of Health Care Workers (HCWs) on TB and TBIC Overall, the HCWs exhibited good level of knowledge. The findings of this study are supported by the findings ofTemesgen & Demissie, (2014) among health professionals in Northwest Ethiopia, where they reported that "majority of the respondents had good TBIC knowledge." However, the observed level of knowledge (64.2%) in this study was lower than the 74.4% reported by Temesgen and Colleague. This is congruent with finding from a survey in rural South Africa where more than 90% of health care professionals identified the classical TB symptoms other than fever, which was identified by 58.9% (Kanjee, Catterick, Moll, Amico, & Friedland, 2011). Similarly, the level of knowledge reported in this study is consistent with the finding of Buregyeya, Kasasa, et aI., (2016) where 69% of the Health Care Workers studied were classified as having adequate knowledge. Also, the level of knowledge on TBIC was generally high among health care professionals in rural South Africa (Kanjee et aI., 20 II). 70 University of Ghana http://ugspace.ug.edu.gh Although most health workers in this study rightly identified the classical symptoms ofTB, mode ofTB transmission, proper cough etiquettes, and persons with high risk ofTB spread, a significant majority (73.7%) failed to identify fever as part of the symptoms, hence the relatively lower level of knowledge recorded. The overall knowledge level had a bearing on the level of practice since approximate equal level of practice was found. In this study, only gender, marital status and current unit of work were found to have significant association with TBIC knowledge level. Knowledge was highest amongst females (70.6%) than males, the married (72.4%) compared to the single and divorced HCWs. Similarly, knowledge was higher (100%) among those working at the DOTS and ART units than those in the other units. This result is similar to a research conducted in North Eastern Nigeria on HCWs' knowledge, awareness and compliance with standard precautions, which reported that women had higher knowledge than men (Abdulraheem, Amodu, Saka, Bolarinwa, & Uthman, 2012). The high knowledge levels among the workers at the DOTS and ART units could be due to their direct daily involvement in TB care and education of patients and the public on TB and its control. On the other hand, only 30% of the staff at the laboratory had good knowledge on TB and TBIC, which may be due to their focus on working on specimen rather than interacting and/or educating patients and the public, which they perceived as the role of those directly involved with patient care. On the other hand, educational status, job category, training, professional working years, and years worked in facility did not have any significant relationship with level of kno .... ledge. This is contrary to the findings of Demissie Gizaw et aI., (2015) where educational status was significantly associated with level of knowledge. The reason for the difference may be attributed to the diflerent categories of educational status used for the 71 University of Ghana http://ugspace.ug.edu.gh two studies; this study categorized it into primary, secondary, tertiary and other levels, while Demissie Gizaw and colleagues categorized educational status into diploma, first degree, and second degree and above. Further, this study did not find any significant association between level of knowledge and training received on TB infection control. However, this contrasts the findings of Temesgen & Demissie, (2014) where training was statistically significant with level of TBIC knowledge. The probable reason in this study may be due to improper staff attitude towards training. 5.2 Level of Practice of HCWs on TB and TBIC The overall level of practice of the HCWs was good with more than half (60.6%) of the HCWs having good TBIC practice. This is consistent with the report from Northwest Ethiopia where they recorded an overall level of practice of63.3% (Temesgen & Demissie, 2014). However, the level of practice in this study was higher than what was recorded by Tamir et aI., (2016) in the West Goijam Zone, Ethiopia (38.0%) and by Demissie Gizaw et al., (2015) in Addis Ababa, Ethiopia (48.6%). This study also highlights that 91.2% of the HeWs indicate that they screen suspects for TB in the facility. This is higher than the study done in Ethiopia, where 71.6% of the health workers reported that they undertake TB screening at their departments (Tamir et aI., 2016), and a study in Uganda, where only 43% of health professionals claimed to screen suspects for TB (Buregyeya et aI., 2013). The high level of screening in the facility of this stud) rna) mainly be due to the presence of task-shifting officers positioned at various units to pick-up any TB suspect for screening. It may also be influenced by the presence of a 72 University of Ghana http://ugspace.ug.edu.gh committed TB Coordinator and team, as deduced from the direct observation and key informant interviews. Regarding the use of personal protective equipment (N95 respirators and surgical masks), 82.5% of them reported that they use PPEs when attending to high risk individuals. From the direct observation done in this study, N95 respirators were rarely used and were reserved for the management of suspected MDR cases. A study by Tamir and colleagues recorded low proportion of health professionals (23.5%) use of N-95 respirators at the health centers (Tamir et aI., 2016). The discrepancies in the proportions may be explained by the high usage of surgical masks instead of the N95 respirators by the HCWs in this study. Kanjee and Colleagues (2011) reported that more than half (54.7%) of their respondents "always" used respirators when attending to TB case or suspects in rural South Africa (Kanjee et aI., 2011). On the contrary, fast tracking of smear positive cases to minimize patient stay in hospital was minimally practiced by the health care workers (27.01%), as was similarly observed in other studies (Brouwer et aI., 2014; Temesgen & Demissie, 2014). In this study, patients were attended to on "first come, first served" basis. This inability to fast track patients may be due to high patient turnout and high workload on staff as observed through direct observation. In addition, only 24.1% of HCWs slated that they educate patients on cough etiquette and this is lower than 77.4% reported in South Africa (Kanjee et aI., 2011), and 60% in Ethiopia (Tamir et aI., 2016). The findings of this study reveal further that job category, professional working years, current unit of work and level of knowledge were significantly associated with TBIC practice levels among Ilews (p<0.05). Similar finding were recorded by Tamir et aI., (2016) where the working department of the health professionals as well as their knowledge 73 University of Ghana http://ugspace.ug.edu.gh status influenced the level of TBIC practice. Tuberculosis Infection Control practices is highest among doctors (84.0%) in this study compared to the other professionals. Also, HCWs with professional working years of 20 and above have the highest level of good practice compared to other range of years. In terms of current unit of work, it was recorded that practice ofTBIC measures is highest among workers of the medical unit (86.7%) than all other units, whereas less than half (44.4%) of the 1 workers directly related with TB care - DOTS and ART units- have good practice. This is contrary to findings by Demissie Gizaw et al. (2015), where experience in TB clinic was a major predictor of practice. Furthermore, a significant relationship was identified between HCWs' knowledge on TB and TBIC, and their practice irrespective of other factors. Majority (72.7%) of the participants with good knowledge had good level of TBIC practice. Those with good knowledge were 4.1 times more likely to exhibit good practice compared to those with poor knowledge. This supports the findings of Temesgen & Demissie (2014), where knowledge was a strong predictor of good TBIC practice. The high proportion of HCWs at the medical unit with good practice may be because the medical unit is directly responsible for housing patients with TB and other infectious diseases within the facility. On the contrary, gender, age, marital status, years worked in the facility, presence of a known medical condition, and training on TBIC are not significant with level of TBIC practice, unlike the findings of Demissie Gizaw and colleagues, where tuberculosis-related training was significantly associated with TBIC practice (Demissie Gizaw et al.. 2015). 74 University of Ghana http://ugspace.ug.edu.gh 5.3 Service Factors Influencing Sustained Implementation of TBIC Health Care Workers perceived screening of patients. availability of separate TB laboratory and availability of personal protective equipment as the service factors promoting sustained implementation of TBIC in this study. However. a study in Mozambique. assessing the challenges faced by health care workers showed that prioritization of patients with cough, use of respirators. cough hygiene. proper ventilation and education were perceived as the most important measures (Brouwer et aI., 2014). On the other hand. this study identified inadequate TBIC materials (policy, IEC materials PPEs etc). lack of an isolation ward and the absence of staff screening as service factors perceived by the HCWs to be inhibiting sustained implementation ofTB infection Control in the facility. Participants (48.9%) reported that there is a TBIC policy within the facility. but most of the responses from the Klls rather indicated the absence of a TBIC policy in the facility. A survey of knowledge. attitude and practice of staff on TBIC in rural South Africa indicated that insufficient supply of PPEs (respirators) were the perceived barriers to sustained implementation of TB Infection Control (Kanjee et al.. 2011). Also. Brouwer and colleagues in their study identified lack of necessary TBIC materials or equipment (respirators and other protective equipment) and lack of clear guidelines as part of the challenges to effective implementation. One of the health care providers stated that, . There is priority to give respirators 10 the TB program, isn 'I it? We, Ihe others, use those o/paper that do not protect at all. "-Medical (Brouwer et al.. 2014). 75 University of Ghana http://ugspace.ug.edu.gh Concerning the periodic screening of staff for TB, majority of the responses indicate that there was no such measure in the facility. However, some of the key informant interviews reveal that such measures exist but poorly patronized due to stigmatization and poor staff attitude. Staff screening was identified as a critical part of reducing TB transmission in healthcare settings (Costa, Silva. Ferreira. & Nienhaus, 2011). 5.4 Environmental Facton Influencing Sustained Implementation ofTBIC All the environmental factors in this study are perceived to be inhibitors rather than promoters of sustained implementation of TBIC measures in the facility. These factors included small waiting area, poor ventilation system, and absence of a well-ventilated sputum booth for safe sputum production and disposal. Over 50% of the responses from the participants indicate that the sizes of the patients waiting areas are small to accommodate patients without crowding. Similar findings were reported from a study in Mozambique in which it was stated that poor infrastructure, inadequate space and lack of fans were perceived as challenges to use TBIC measures. According to a respondent of that study, "Our physical space is small. [. .. ] There are no fans. nothing. .. -Medical (Brouwer et aI., 2014). A study in Uganda by Buregyeya et aI., (2013) also showed that less than 50% of patient waiting rooms were adequately ventilated. The small size of the waiting areas can be mainly due to the old facility structure, which was built over three decades ago; however, new facilities are being added to reduce the crowding. Most (96.4%) of the participants who use natural ventilation report that they "always" open the doors and windows during work hours, compared to a 65.5% and 69.1 % recorded for 76 University of Ghana http://ugspace.ug.edu.gh doors and windows respectively in South Africa (Kanjee et aI., 2011). This agrees with the findings from the direct observation at the study site. The high discrepancy may be attributed to the temperate climate of the study location relative to South Africa. The facility had no vantage point or sputum booth for safe sputum production and disposal; as such, patients are directed to produce sputum samples in open locations, potentially exposing the whole populace to TB nuclei droplets. The unavailability of the booth can be attributed to the lack of space within the facility. 77 University of Ghana http://ugspace.ug.edu.gh CHAPTER SIX CONCLUSION AND RECOMMENDATION 6.1 Conclusion The overall level of knowledge and practice of TB Infection Control measures among Health Care Workers at the Greater Accra Regional Hospital is good. Generally, female health care workers have better knowledge than the males. Current unit of work is significantly associated with level of knowledge. Also, level of knowledge of TB and TBIC, and job category are the main significant predictors ofTBIC practice. The main service factor promoting sustained implementation of TBIC is the screening of suspected TB patients. However, inadequate TBIC materials (TBIC policy, IEC materials and PPEs), lack of an isolation ward and absence of staff screening for TB are perceived to be the major inhibiting factors to effective implementation ofTBIC measures. 6.2 Recommendations I. The Management of the Greater Accra Regional Hospital should work closely with the TB coordinator to ensure periodic staff screening for TB. 2. The Management of the Greater Accra Regional Hospital should provide properly ventilated isolation units for separating infectious TB patients. 3. The HCWs need to be supervised by both hospital management and NTP to ensure that TBIC measures/practices are strictly adhered to within the hospital setting. 4. The National Tuberculosis Programme (NTP) should ensure that adequate logistics (TBIC policy, PPEs and IEC materials) are made available for sustained implementation ofTBIC measures. 78 University of Ghana http://ugspace.ug.edu.gh REFERENCES Abdulraheem, I., Amodu, M., Saka, M., Bolarinwa, 0., & Uthman, M.
