Why is there a gap in self-rated health among people with hypertension in Zambia? A decomposition of determinants and rural‒urban differences.

BACKGROUND: Hypertension affects over one billion people globally and is one of the leading causes of premature death. Low- and middle-income countries, especially the sub-Saharan Africa region, bear a disproportionately higher share of hypertension globally. Recent evidence shows a steady shift in the burden of hypertension from more affluent and urban populations towards poorer and rural communities. Our study examined inequalities in self-rated health (SRH) among people with hypertension and whether there is a rural‒urban gap in the health of these patients. We then quantified factors driving the health gap. We also examined how much HIV accounts for differences in self-rated health among hypertension patients due to the relationship between HIV, hypertension and health in sub-Saharan Africa. METHODS: We utilized the Zambia Household Health Expenditure and Utilization Survey for data on SRH and other demographic and socioeconomic controls. District HIV prevalence information was from the Zambia Population-Based HIV Impact Assessment (ZAMPHIA) survey. We applied the Linear Probability Model to assess the association between self-rated health and independent variables as a preliminary step. We then used the Blinder-Oaxaca decomposition to identify self-rated health inequality between urban and rural patients and determine determinants of the health gap between the two groups. RESULTS: Advanced age, lower education and low district HIV prevalence were significantly associated with poor health rating among hypertension patients. The decomposition analysis indicated that 45.5% of urban patients and 36.9% of rural patients reported good self-rated health, representing a statistically significant health gap of 8.6%. Most of the identified health gap can be attributed to endowment effects, with education (73.6%), district HIV prevalence (30.8%) and household expenditure (4.8%) being the most important determinants that explain the health gap. CONCLUSIONS: Urban hypertension patients have better SRH than rural patients in Zambia. Education, district HIV prevalence and household expenditure were the most important determinants of the health gap between rural and urban hypertension patients. Policies aimed at promoting educational interventions, improving access to financial resources and strengthening hypertension health services, especially in rural areas, can significantly improve the health of rural patients, and potentially reduce health inequalities between the two regions.

Methods: We utilized the Zambia Household Health Expenditure and Utilization Survey for the data on SRH and other demographic and socioeconomic controls. District HIV prevalence information was from a previous study. The linear probability model provided a preliminary assessment of the association between self-rated health and independent variables. We then used the Blinder-Oaxaca decomposition to identify self-rated health inequality between urban and rural patients and determine determinants of the health gap between the two groups. Results: Advanced age, lower education and low district HIV prevalence were significantly associated with poor health rating among hypertension patients. The decomposition analysis indicated that 45.5% of urban patients and 36.9% of rural patients reported good self-rated health, representing a statistically significant health gap of 8.6%. Most of the identified health gap can be attributed to endowment effects, with education (62%), district HIV prevalence (26%) and household expenditure (12%) being the most important determinants that explain the health gap. Conclusions: Urban hypertension patients have better SRH than rural patients in Zambia. Educational interventions, financial protection schemes and strengthening hypertension health services in rural areas can significantly reduce the health gap between the two regions.

Facilitators and barriers to implementation of integrated community case management of childhood illness: a qualitative case study of Kapiri Mposhi District.

BACKGROUND: Zambia adopted the Integrated Community Case Management (ICCM) of childhood illness strategy in May 2010, targeting populations in rural communities and hard-to-reach areas. However, evidence suggests that ICCM implementation in local health systems has been suboptimal. This study sought to explore facilitators and barriers to implementation of ICCM in the health system in Kapiri Mposhi District, Zambia. METHODS: Data were gathered through 19 key informant interviews with district health managers, ICCM supervisors, health facility managers, and district health co-operating partners. The study was conducted in Kapiri Mposhi district, Zambia. Interviews were translated and transcribed verbatim. Data were were analyzed using thematic analysis in NVivo 11(QSR International). RESULTS: Facilitators to implementation of ICCM consisted of community involvement and support for the program, active community case detection and timeliness of health services, the program was not considered a significant shift from other community-based health interventions, district leadership and ownership of the program, availability of national and district-level policies supporting ICCM and engagement of district co-operating partners. Program incompatibility with some socio-cultural and religious cotexts, stock-out of prerequisite drugs and supplies, staff reshuffle and redeployment, inadequate supervision of health facilities, and nonpayment of community health worker incentives inhibited implementation of ICCM. CONCLUSION: The study findings highlight key faciliators and barriers that should be considered by policy-makers, district health managers, ICCM supervisors, health facility managers, and co-operating partners, in designing context-specific strategies, to ensure successful implementation of ICCM in local health systems.

Estimating district HIV prevalence in Zambia using small-area estimation methods (SAE).

BACKGROUND: The HIV/AIDS pandemic has had a very devastating impact at a global level, with the Eastern and Southern African region being the hardest hit. The considerable geographical variation in the pandemic means varying impact of the disease in different settings, requiring differentiated interventions. While information on the prevalence of HIV at regional and national levels is readily available, the burden of the disease at smaller area levels, where health services are organized and delivered, is not well documented. This affects the targeting of HIV resources. There is need, therefore, for studies to estimate HIV prevalence at appropriate levels to improve HIV-related planning and resource allocation. METHODS: We estimated the district-level prevalence of HIV using Small-Area Estimation (SAE) technique by utilizing the 2016 Zambia Population-Based HIV Impact Assessment Survey (ZAMPHIA) data and auxiliary data from the 2010 Zambian Census of Population and Housing and the HIV sentinel surveillance data from selected antenatal care clinics (ANC). SAE models were fitted in R Programming to ascertain the best HIV predicting model. We then used the Fay-Herriot (FH) model to obtain weighted, more precise and reliable HIV prevalence for all the districts. RESULTS: The results revealed variations in the district HIV prevalence in Zambia, with the prevalence ranging from as low as 4.2% to as high as 23.5%. Approximately 32% of the districts (n = 24) had HIV prevalence above the national average, with one district having almost twice as much prevalence as the national level. Some rural districts have very high HIV prevalence rates. CONCLUSIONS: HIV prevalence in Zambian is highest in districts located near international borders, along the main transit routes and adjacent to other districts with very high prevalence. The variations in the burden of HIV across districts in Zambia point to the need for a differentiated approach in HIV programming within the country. HIV resources need to be prioritized toward districts with high population mobility.

Access barriers to maternal healthcare services in selected hard-to-reach areas of Zambia: a mixed methods design.

INTRODUCTION: poor access to maternal health services is a one of the major contributing factors to maternal deaths in low-resource settings, and understanding access barriers to maternal services is an important step for targeting interventions aimed at promoting institutional delivery and improving maternal health. This study explored access barriers to maternal and antenatal services in Kaputa and Ngabwe; two of Zambia´s rural and hard-to-reach districts. METHODS: a concurrent mixed methods approach was therefore, undertaken to exploring three access dimensions, namely availability, affordability and acceptability, in the two districts. Structured interviews were conducted among 190 eligible women in both districts, while key informant interviews, in-depth interviews and focus group discussions were conducted for the qualitative component. RESULTS: the study found that respondents were happy with facilities´ opening and closing times in both districts. By comparison, however, women in Ngabwe spent significantly more time traveling to facilities than those in Kaputa, with bad roads and transport challenges cited as factors affecting service use. The requirement to have a traditional birth attendant (TBA) accompany a woman when going to deliver from the facility, and paying these TBAs, was a notable access barrier. Generally, services seemed to be more acceptable in Kaputa than in Ngabwe, though both districts complained about long queues, being delivered by male health workers and having delivery rooms next to male wards. CONCLUSION: based on the indicators of access used in this study, maternal health services seemed to be more accessible in Kaputa compared to Ngabwe.

A needs assessment for postgraduate training in selected public health disciplines: evidence from health services organisations in Lusaka, Zambia.

BACKGROUND: As most low and middle-income countries seek to achieve universal health coverage targets, there is an ever-increasing need to train human resources with the required core skills and competencies. This study reports on a needs assessment conducted among health services organisations (HSOs) to understand postgraduate training needs and service gaps for selected public health disciplines - Health Policy and Systems, Health Economics, and Healthcare Management and Planning - at the University of Zambia. METHODS: The study adopted a cross-sectional design, comprising qualitative and quantitative components. Data were collected using semi-structured questionnaires administered to 32 representatives of purposively sampled public and private health service organisations based in Lusaka Zambia. The health services organisations included regulatory authorities, research institutions, government ministries, insurance firms and other cooperating partners. RESULTS: Overall (n = 22), more than 68% of the stakeholders reported that they had no employees that were formally trained in the three disciplines. More than 90% of the stakeholders opined that training in these disciplines would be beneficial in providing competencies to strengthen service provision. The horizontal skills mismatch for health economics, and health services management and planning were found to be 93 and 100%, respectively. Among the critical public health training needs were: policy development and analysis, economic evaluation, and strategic management. CONCLUSIONS: This study confirms that introducing post-graduate training in the proposed public health disciplines will not only benefit Zambian health services organisations but also help strengthen the health systems in general. For other empirical contexts, the findings imply the need for the introduction of academic programmes which respond to ever-changing public health skills demanded. They should be matched with local priorities and service delivery.

Providing monetary and non-monetary goods to research participants: perspectives and practices of researchers and Research Ethics Committees in Zambia.

There are disagreements among ethicists on what comprises an "appropriate" good to offer research participants. Debates often focus on the type, quantity, timing, and ethical appropriateness of such offers, particularly in settings where participants may be socio-economically vulnerable, such as in parts of Zambia. This was a Cross-sectional online survey of researchers and Research Ethics Committees (RECs) designed to understand practices, attitudes and policies associated with provision of goods to research participants. Of 122 responding researchers, 69 met eligibility criteria. Responses were also received from five of the six Zambian RECs involved in reviewing research proposals. Forty-nine researchers (71.0%) confirmed previous experience offering goods to participants. Of these, 21 (42.9%) offered participants money only, 18 (36.7%) offered non-monetary goods, while the rest offered both monetary and non-monetary goods. Generally, goods were offered and approved by RECs to compensate for time, lost wages and transportation. One REC and 34.8% of researchers reported being subject to an institutional policy on offering goods to participants. While reimbursement is the main reason for offering goods to participants in Zambia, caution is required when deciding on the type and quantity of goods to offer given the potential for community mistrust and manipulation.
