Item The Role of the Private Sector in the COVID-19 Pandemic: Experiences From Four Health Systems(Frontiers in Public Health, 2022) Wallace, L.J.; AgyepongI., I.; Nonvignon, J.; et al.As societies urbanize, their populations have become increasingly dependent on the private sector for essential services. The way the private sector responds to health emergencies such as the COVID-19 pandemic can determine the health and economic wellbeing of urban populations, an effect amplified for poorer communities. Here we present a qualitative document analysis of media reports and policy documents in four low resource settings-Bangladesh, Ghana, Nepal, Nigeria-between January and September 2020. The review focuses on two questions: (i) Who are the private sector actors who have engaged in the COVID-19 first wave response and what was their role?; and (ii) How have national and sub-national governments engaged in, and with, the private sector response and what have been the effects of these engagements? Three main roles of the private sector were identified in the review. (1) Providing resources to support the public health response. (2) Mitigating the financial impact of the pandemic on individuals and businesses. (3) Adjustment of services delivered by the private sector, within and beyond the health sector, to respond to pandemic-related business challenges and opportunities. The findings suggest that a combination of public-private partnerships, contracting, and regulation have been used by governments to influence private sector involvement. Government strategies to engage the private sector developed quickly, reflecting the importance of private services to populations. However, implementation of regulatory responses, especially in the health sector, has often been weak reflecting the difficulty governments have in ensuring affordable, quality private services. Lessons for future pandemics and other health emergencies include the need to ensure that essential non-pandemic health services in the government and non-government sector can continue despite elevated risks, surge capacity to minimize shortages of vital public health supplies is available, and plans are in place to ensure private workplaces remain safe and livelihoods protected.Item Exploring barriers to accessing physiotherapy services for stroke patients at Tema general hospital, Ghana(Archives of Physiotherapy, 2017) Nketia-Kyere, M.; Aryeetey, G.C.; Nonvignon, J.; Aikins, M.Background: Physiotherapy has been shown to reduce the risk of disability among stroke patients. Poor adherence to physiotherapy can negatively affect outcomes and healthcare cost. However, very little is known about barriers especially to physiotherapy services in Ghana. The objective of this study was to assess the barriers to physiotherapy services for stroke patients at Tema General Hospital (TGH). The individual/personal and health system barriers to physiotherapy services at TGH were determined. Method: A cross-sectional study design was employed. A simple random sampling technique was used to recruit 207 respondents for a face-to-face interview. Interviewer-administered questionnaires were used to collect data on individual/personal barriers of respondents to physiotherapy services and were described using the Likert’s scale. Health system barriers were assessed using a self-structured questionnaire which had section under the following heading: human factors, physiotherapy modalities, physical barriers and material/equipment factors. The time spent waiting for physiotherapy and attitude of physiotherapist towards patients; physiotherapy modality such as electrotherapy, exercise therapy and massage therapy among others were some of the indices measured. Respondents’ adherence to Medication was assessed with the Morisky 8-item medication adherence questionnaire. Data were entered and analysed using Epi info 7 and STATA 12.0. Associations between the variables were determined using a chi-square test and logistic regression model was used to test the strength of associations between the independent and the dependent variables. The level of statistical significance was set at p < 0.05. Results: The results showed that majority (76.3%) of the respondents had economic barrier as their main individual/ personal barrier to physiotherapy services. For medication adherence level, patients with low medication adherence level were about 21 times the odds of defaulting on accessing physiotherapy services five times or more as compared to those with medium adherence level (OR 20.63, 95% CI 8.96, 42.97). It was concluded in the study that individual/ personal barriers of stroke patients were the significant barriers to accessing physiotherapy services at Tema General Hospital.Item Economic Analysis of Health Inequality Among the Elderly in Ghana(Journal of Population Ageing, 2020) Fonta, C.L.; Nonvignon, J.; Aikins, M.; Nonvignon, J.; Aryeetey, G.C.In Ghana, the ageing population is growing at a fast pace amidst challenging socioeconomic environment. As such, the health of elderly persons in Ghana is of emerging concern and of high priority to the Government. In this study, we seek to measure health inequality among elderly persons in Ghana to determine its existence and explore the factors driving it. Data for the study were drawn from the World Health Organization (WHO)‘s Study on Global Ageing and Adult Health (SAGE Wave 1) and analyzed using STATA and a Distributive Analysis Stata Package (DASP) installed in STATA. Health inequality was measured using concentration curves and concentration index (CI). Furthermore, a regression-based approach was used to determine factors associated with health inequality and their estimated contributions to health inequality. The CI for poor SRH was −0.059 indicating greatest poor health among the poor. The highest contributors to health inequality were presence of at least a chronic condition (63.4%), followed by the age group 70 years and above (26.6%), being single (13.9%), poor (3.9%) and uneducated (0.3%). The probability of reporting poor health was higher with increasing age (Coeff = 0.27, p < 0.05), having at least a chronic condition (Coeff = 0.34, p < 0.05), being single (Coeff = 0.14, p < 0.05) and being poor (Coeff = 0.17, p < 0.05). The results show that health inequality exists among the elderly in Ghana and that poor health was greatest among the poor. Socioeconomic, demographic and health related factors are associated with health inequality.Item Strengths, disconnects and lessons in local and central governance of the response to the first wave of COVID-19 in Ghana(Ghana Medical Journal, 2022) Wallac, L.J.; Afun, N.E.E.; Nonvignon, J.; et al.Objectives: To explore governance, coordination and implementation actors, structures and processes, facilitators, and barriers within local government and between central and local government in Ghana’s COVID-19 response dur ing the first wave of the outbreak. Design: Cross-sectional single case study. Data collection involved a desk review of media, policy and administrative documents and key informant in-depth interviews. Setting: Two municipalities in the Greater Accra region of Ghana Participants: Local government decentralised decision makers and officials of decentralised departments. Interventions: None. Main Outcome Measures: None Results: Coordination between the national and local government involved the provision of directives, guidelines, training, and resources. Most of the emergency response structures at the municipal level were functional except for some Public Health Emergency Management Committees. Inadequate resources challenged all aspects of the re sponse. Coordination between local government and district health directorates in risk communication was poor. Dur ing the distribution of relief items, a biased selection process and a lack of a bottom-up approach in planning and implementation were common and undermined the ability to target the most vulnerable beneficiaries. Conclusions: Adequate financing and equipping of frontline health facilities and workers for surveillance, laboratory and case management activities, transparent criteria to ensure effective targeting and monitoring of the distribution of relief items, and a stronger bottom-up approach to the planning and implementation of interventions need to be given high priority in any response to health security threats such as COVID-19.Item Health systems, population and patient challenges for achieving universal health coverage for hypertension in Ghana(Health Policy and Planning, 2021) Koduah, A.; Nonvignon, J.; Colson, A.; et al.Ghana has signed on to the United Nations Sustainable Development Goal to achieve universal health coverage (UHC), ensuring that all individu als receive the health care they require without financial hardship. Achieving that goal is a difficult task in any setting. The challenges are further exacerbated by a changing disease landscape, as the burden of non-communicable diseases (NCDs) is increasing and creating a dual burden along with infectious diseases. This study explores the existing health system for delivering hypertension care and the challenges of delivering UHC for hypertension in Ghana. Document analysis of national health reports, policies and legislations along with a review of research articles was conducted to explore the challenges of delivering UHC for NCDs in Ghana, and hypertension in particular. The main themes and indicators related to the challenges of delivering UHC for hypertension were mapped and analysed. The main challenges to delivering UHC for hypertension can be grouped into population and patient, on the one hand, and health system factors, on the other. Population and patient factors include (1) unhealthy lifestyles overburdening the health system, (2) poor health-seeking behaviour and (3) poor adherence to medication, which has led to uncontrolled cases and poor clinical outcomes even among treated patients with hypertension. Health system factors include (1) inadequate health system capacity for early diagnosis due to an increasing number of patients, (2) inequitable distribution of health care facilities affecting access, (3) finan cial sustainability of the National Health Insurance Scheme and delays in reimbursement of claims to facilities that affect the health system’s ability to provide timely management of hypertension and (4) health care facilities and practitioners’ use of non-standardized and uncalibrated blood pres sure measuring equipment. Ghana therefore will need to make important decisions to overcome operational and financial challenges on its path to UHC.Item Characterization of functional disability among older adults in Ghana: A multi-level analysis of the study on global ageing and adult health (SAGE) Wave II(PLOS ONE, 2022) Darkwah, K.A.; Iddi, S.; Nonvignon, J.; Aikins, M.Background Functional disability is a common public health problem that affects the health and quality of life of older adults. This causes them to be highly dependent on other members of their fam ily, receive home care, or to be institutionalized. Although functional disability has been widely studied in developed country settings, very limited studies have focused on age related functional disability in sub-Saharan Africa, and in particular Ghana. The purpose of this study is to assess various factors associated with the difficulties in performing basic and instrumental activities of daily living among older adults in Ghana. Methods This cross-sectional study used data on 1610 older adults aged 50 years and above from the Study on Global Ageing and Adult Health (SAGE) survey Wave II conducted in Ghana. Nine standard functioning difficulty tools of WHODAS II was used for the analysis. The WHODAS II offers continuous summary scores with higher scores showing higher disability, and vice versa. A multi-level regression model was used to identify individual and household level risk factors linked to the functional disability of older adults. Results Female older adults (53.7%) reported having functional disability. The mean functional dis ability among older adults aged 50 years and above was 5.2 (± 5.9). Results indicated that older adults who are females, aged 70 years and above, and had three or more chronic con ditions had a higher functional disability. Also, older adults who have adequate fruit intake and belong to wealthier households were found to have a lower functional disability. Conclusions The study reveals that functional disability among older adults is frequent in Ghana and is associated with having three or more chronic conditions and being overweight/obese. Pre vention of functional disability in old age in Ghana is therefore a matter of great social and economic concern, which calls for coordinate efforts across the board to mitigate this public health challengeItem Willingness to pay for kidney transplantation among chronic kidney disease patients in Ghana(PLOS ONE, 2020) Boima, V.; Agyabeng, K.; Nonvignon, J.; et al.Background Kidney transplantation is the preferred treatment for patients with end stage renal disease. However, it is largely unavailable in many sub-Sahara African countries including Ghana. In Ghana, treatment for end stage renal disease including transplantation, is usually financed out-of-pocket. As efforts continue to be made to expand the kidney transplantation pro gramme in Ghana, it remains unclear whether patients with Chronic Kidney Disease (CKD) would be willing to pay for a kidney transplant. Aim The aim of the study was to assess CKD patients’ willingness to pay for kidney transplanta tion as a treatment option for end stage renal disease in Ghana. Methods A facility based cross-sectional study conducted at the Renal Outpatient clinic and Dialysis Unit of Korle-Bu Teaching Hospital among 342 CKD patients 18 years and above including those receiving haemodialysis. A consecutive sampling approach was used to recruit patients. Structured questionnaires were administered to obtain information on demo graphic, socio-economic, knowledge about transplant, perception of transplantation and willingness to pay for transplant. In addition, the INSPIRIT questionnaire was used to assess patients’ level of religiosity and spirituality. Contingent valuation method (CVM) method was used to assess willingness to pay (WTP) for kidney transplantation. Logistic regression model was used to determine the significant predictors of WTP. Results The average age of respondents was 50.2 ± 17.1 years with most (56.7% (194/342) being male. Overall, 90 out of the 342 study participants (26.3%, 95%CI: 21.7–31.3%) were willing to pay for a kidney transplant at the current going price ( $ 17,550) or more. The median amount partici pants were willing to pay below the current price was $986 (IQR: $197 –$1972). Among those willing to accept (67.3%, 230/342), 29.1% (67/230) were willing to pay for kidney transplant at the prevailing price. Wealth quintile, social support in terms of number of family friends one could talk to about personal issues and number of family members one can call on for help were the only factors identified to be significantly predictive of willingness to pay (p-value < 0.05). Conclusion The overall willingness to pay for kidney transplant is low among chronic kidney disease patients attending Korle-Bu Teaching Hospital. Patients with higher socio-economic status and those with more family members one can call on for help were more likely to pay for kid ney transplantation. The study’s findings give policy makers an understanding of CKD patients circumstances regarding affordability of the medical management of CKD including kidney transplantation. This can help develop pricing models to attain an ideal poise between a cost effective but sustainable kidney transplant programme and improve patient access to this ultimate treatment option.Item The Role of the Private Sector in the COVID-19 Pandemic: Experiences From Four Health Systems(Frontiers in Public Health, 2022) Wallace, L.J.; Agyepong, I.; Nonvignon, J.; et al.As societies urbanize, their populations have become increasingly dependent on the private sector for essential services.

Using Ghana as a case study, this article examines the changes COVID-19 has brought to diabetes service delivery and considers policy responses to deal with future such outbreaks. Methods: We conducted 18 interviews between November 2020 and February 2021 with health professionals and administrators from primary, secondary and tertiary facilities within the Ghana Health Service. The analysis was performed using deductive and inductive methods. Results: There were six general themes in interviewees’ responses: (1) COVID-19 had exacerbated the problems of high medicine and service costs and medicine shortages, (2) the pandemic had exacerbated problems of poor patient record keeping, (3) COVID-19 had reduced the availability of suitably trained health providers, (4) staff had become demoralized by management’s unwillingness to make innovative changes to cope with the pandemic, (5) COVID-19 led to a reor ganization of diabetes services, and (6) the country’s national health insurance scheme lacked flexibility in dealing with the pandemic. Conclusions: Access to resources is limited in LMICs. However, our study highlights practical policy responses that can improve health providers’ response to COVID-19 and future pandemicsItem Factors infuencing health workers’ compliance with the WHO intermittent preventive treatment for malaria in pregnancy recommendations in the Northern Region, Ghana(Malaria Journal, 2022) Mohammed, A.G.; Duah, D.; Kenu, E.; Nonvignon, J.; Manu, A.; Bonful, H.A.Background: Although IPTp-SP is a lifesaving World Health Organization (WHO) recommended preventive interven tion for pregnant women in malaria-endemic regions, IPTp-SP uptake in the Northern region of Ghana is much lower than the sub-optimal national coverage level. Assessing the extent of health workers’ compliance and its associated factors will generate valuable pointers to be targeted at the program level. The study examined the factors infuenc ing health workers’ compliance with the WHO recommended guidelines for IPTp-SP in the Northern Region. Methods: A cross-sectional study among 315 health workers in the Northern region was conducted. Semi-structured questionnaires were used to collect data on health workers’ sociodemographic characteristics, facility-based factors and knowledge level. Data were collected on health workers’ compliance with the recommended practices through covert observations using a checklist. Facility observations were carried out using a checklist. Crude and adjusted logistic regression were used to determine predictors of health workers’ compliance, at a 5% signifcance level adjust ing for clustering. Results: Of the 315 health workers studied, the median age was 29 years (26–34 years). Females constituted (80.5%; 252) of the 313 workers. The majority (47.4%;148) of the 312 health workers were midwives. Overall, 56.2% (CI 51.0 – 62.0) were adequately complying with the recommended guidelines. Lower levels of compliance were recorded in health centres 15.6% (5.0 – 33.0) and CHPS compounds 21.2% (11.0 – 35.0). The factors associated with compliance included health workers’ knowledge (aOR=7.64, 95% CI 4.21 – 13.87, p<0.001), job satisfaction (aOR 10.87, 95% CI 7.04 – 16.79, p<0.001), in-service training (aOR 10.11, 95% CI 4.53 – 22.56, p<0.001), supervision (aOR 4.01, 95% CI 2.09 – 7.68, p<0.001), availability of job aids (aOR 3.61, 95% CI 2.44 – 5.35, p<0.001), health workers expe rience (aOR=10.64, 95% CI 5.99 – 18.91, p<0.001) and facility type (aOR 0.03, 95% CI 0.01–0.07, p<0.001). Conclusion: Compliance with the recommended IPTp-SP guidelines is suboptimal in the region, with lower-level health facilities recording the least compliance levels. Health centres and CHPS facilities should be prioritized in dis tributing limited resources to improve health worker quality of care for antenatal care clients
