Estimating the Lifetime Cost of Managing Hypertension in Ghana: A Modelling Study.

Introduction: Over the last decade, hypertension (HPT) is among the leading causes of death and morbidity in Ghana. In recent past, most health policy research in Ghana and Africa focussed on communicable diseases. In recent times, Ghana and other developing nations have shifted their attention to non-communicable diseases because most of these countries are going through an epidemiologic transition where there is a surge in the prevalence of HPT. This paper was therefore set out to estimate the cost of treating HPT in Ghana from the patients' and health system's perspectives. Method: We used a cost of illness framework to simulate the cost of HPT management in Ghana taking into account 4 of the common target organ complications with the most mortality implication. A decision analytic model (DAM) was developed in Microsoft® Excel to simulate the progression of HPT patients and the Markov model was employed in simulating the lifetime cost of illness. Results: The results show that by 10 years from diagnosis, the probability of death from any of the 4 complications (ie, stroke, myocardial infarction, heart failure, and chronic kidney disease) is roughly 41.03%. By 20 years (or 243 months) from diagnosis, the probability of death is estimated to be 69.61%. However, by the 30th anniversary, the probability of death among the cohort is 82.3%. Also, the lifetime discounted cost of treating HPT is about GHS 869 106 which could range between GHS 570 239 and GHS 1.202 million if wide uncertainty is taken into account. This is equivalent to USD 119 056 (range: USD 78 115-164 723). Conclusion: By highlighting the lifetime cost of treating HPT in Ghana, policies can be formulated regarding the cost of treating HPT by the non-communicable disease unit and National Health Insurance Authority (NHIA) of the Ministry of Health.

Predictors of Nonadherence to Medications among Hypertensive Patients in Ghana: An Application of the Health Belief Model.

Introduction: Hypertension (HPT) is recognized as a significant public health problem worldwide from a health and economic perspective. This study determined predictors of nonadherence to HPT medications in Ghana using the health belief model. Methods: A cross-sectional descriptive survey employing a quantitative approach was conducted among HPT patients who routinely attend clinics at selected hospitals in the Brong Ahafo region of Ghana. Respondents (n = 399) were recruited using a multistage sampling technique. Results: The prevalence of nonadherence was 63.7% (n = 254). Nonadherence to hypertension medication was associated with lower education status (p=0.009). In logistic regression analysis, patients with high "perceived susceptibility" and "perceived severity" were more likely to forfeit their HPT medication schedules, while patients with high "perceived barriers" and "cues to action" were less likely to skip their medication. Conclusion: The present study suggests a plausible path to improving medication adherence in this population. Given the high prevalence of nonadherence, policymakers need to urgently design tailor-made health promotion interventions to ensure optimal health outcomes.

Preaching to the choir? The influence of personal relevance on the effects of gain- and loss-framed health-promoting messages.

This article examines the moderating influence of personal relevance on the persuasive effects of gain- and loss-framed messages. We assessed current behaviour as a proxy for personal relevance, provided 169 participants with gain- and loss-framed messages advocating skin self-examination (SSE) and assessed intention to engage in SSE as the outcome measure. The results showed that loss-framed information was more persuasive than gain-framed information, but only for low-relevance participants. This suggests that loss-framed information might be mainly effective for recipients who need little persuading and, in fact, runs the risk of 'preaching to the choir'.

The effects of scenario-based risk information on perceptions of susceptibility to Chlamydia and HIV.

The simulation heuristic of Kahnemann and Tversky (1982) suggests that the subjective ease by which a risky situation can be mentally construed, positively influences the person's perceived susceptibility to the presented threat. Assuming that a detailed outline of how a risky event can end up negatively increases the ease of imagination, we tested the hypothesis that scenario-based risk information enhances perceived susceptibility towards contracting a sexually transmitted infection (STI). In an experimental design, undergraduate students were exposed to one or two risk scenario messages or no scenario message (control). The results confirmed the hypothesis, but only when more than one risk scenario message was provided. This adds to the evidence that presenting scenario-based messages could be a feasible method to influence risk perceptions.

The effectiveness of a peer-led HIV/AIDS and STI health education intervention for prison inmates in South Africa.

This article reports on the effectiveness of the first systematically developed health education intervention for the reduction of risky sexual behavior among soon-to-be-released prisoners in South Africa. Data from three out of four prisons are eligible for data analysis including 263 inmates. Using a nested experimental design, short-term evaluation while inmates were still in prison demonstrate that experimental groups showed higher knowledge of sexually transmitted infections and had a more positive intention to reduce risky behavior than the control group in two out of three prisons. Long-term assessment 3 to 6 months after release from prison indicates that experimental groups were more positive about sexual communication, self-efficacy, and intention. Groups educated by an HIV-negative educator perform marginally better than those in groups with an HIV-positive peer educator. It is argued that peer-led health education programs may be effective in reducing risky behavior amongst soon-to-be-released inmates.

Access point analysis on the state of health care services in South African prisons: a qualitative exploration of correctional health care workers' and inmates' perspectives in Kwazulu-Natal and Mpumalanga.

This paper explores inmates and prison health care workers perceptions of the state of health care services in four correctional facilities in South Africa. Structural and organisational issues are explored in terms of how they impact the delivery and provision of health care to inmates within correctional facilities. Additionally, the study forms an access point analysis of prisons as a health care setting as part of the development and testing of a STI/HIV health education intervention for soon to be released inmates. Focus group discussions (6-8 participants per group) were conducted with male inmates in four facilities in KwaZulu-Natal and Mpumalanga provinces. Individual face-to-face interviews were conducted with eight health personnel to get a view from both providers and end users of health care in correctional settings. Data were analysed thematically. We found strong evidence of prison being a strategic point to increase access to health services for offenders. Curative services within prisons were well established and running despite the presence of certain challenges varying across institutions. Prevention programmes emerged as an area that requires stronger emphasis to facilitate imparting skills and promoting safer practices for inmates upon release. Peer-led education programmes emerged as a key aspect of preparation for release and community reintegration amongst inmates.
