Assessing Patient Satisfaction And Some Related Factors In The Kasena Nankana District-Ghana
(International Journal of Scientific and Technology Research, 2018-12) Affi, P.O.; Duah, K.O.; Oppong, I.
To access the relationship between patient satisfaction and some contributing factors, a study was conducted on 200 patients from the War Memorial Hospital. 54% of the patients were males whilst 46% were females. About 67% of the patients were satisfied meaning the satisfaction level at the hospital is higher. A logistic regression model was developed to establish a relationship between patient satisfaction and some contributing factors (age, sex, education, job, health, LTIME, AESTH, PHWR and NHIS). The result indicates that the most important variables associated with patient satisfaction are Sex, LTIME (length of time in attaining services), AESTH (aesthetic features) and PHWR (Patient health-worker relationship).
Canonical Correlation Analysis Of Neonatal Anthropometric Indicators And Maternal Socio-Demographic Factors
(INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH, 2019-07) Affi, P.O.; Lartey, L.N.; Angkyiire, D.; Oppong, I.
Abstract : The main objective of this study was to examine the relationship between neonatal anthropometric indicators (Baby head circumference, Baby full length and Baby weight) and maternal socio demographic factors (Gravidity, Parity, Educational level, Age, occupation of mother and number of ANC visit) using canonical correlation analysis. The neonatal anthropometric indicators were considered as depended (Y) variables whiles maternal socio demographic factors were considered as independent variables (X). The outcome of the canonical correlation analysis showed th at, there exists a significant relationship between neonatal anthropometric indicators (Baby head circumference, Baby full length and Baby weigh t) and maternal socio demographic factors (Gravidity, Parity, Educational level, Age, occupation of mother and number of ANC visi t). The total shared variance between the two set of variables was 69. 8 %. The study also showed that Baby head circumference has a positive relationship with maternal Age and also negative relationship with the remaining of the maternal socio demographic f actors whiles Baby full length and Baby weight also has a positive relationship with all the maternal socio demographic factors used in the study except maternal Age.
Modelling the Transmission Dynamics of Tuberculosis in the Ashanti Region of Ghana
(Interdisciplinary Perspectives on Infectious Diseases, 2020-03-31) Mettle, F.O.; Affi, P.O.; Twumasi, C.
Mathematical models can aid in elucidating the spread of infectious disease dynamics within a given population over time. In an attempt to model tuberculosis (TB) dynamics among high-burden districts in the Ashanti Region of Ghana, the SEIR epidemic model with demography was employed within both deterministic and stochastic settings for comparison purposes. /e deterministic model showed success in modelling TB infection in the region to the transmission dynamics of the stochastic SEIR model over time. It predicted tuberculosis dying out in ten of twelve high-burden districts in the Ashanti Region, but an outbreak in Obuasi municipal and Amansie West district. /e effect of introducing treatment at the incubation stage of TB transmission was also investigated, and it was discovered that treatment introduced at the exposed stage decreased the spread of TB. Branching process approximation was used to derive explicit forms of relevant epidemiological quantities of the deterministic SEIR model for stability analysis of equilibrium points. Numerical simulations were performed to validate the overall infection rate, basic reproductive number, herd immunity threshold, and Malthusian parameter based on bootstrapping, jackknife, and Latin Hypercube sampling schemes. It was recommended that the Ghana Health Service should find a good mechanism to detect TB in the early stages of infection in the region. Public health attention must also be given to districts with a potentially higher risk of experiencing endemic TB even though the estimates of the overall epidemic thresholds from our SEIR model suggested that the Ashanti Region as a whole had herd immunity against TB infection.
