Recours aux soins de santé des indigents et des personnes âgées en Afrique de l’Ouest : cas du Burkina Faso et du Nigeria

Problem  In African countries with point-of-service healthcare user fees, financial barriers are one of the major obstacles to healthcare-seeking behaviour, and the indigent, the poorest members of society, are the most affected. To address this issue, some countries have begun developing health programs targeting indigent people to help them gain better access to healthcare by waiving healthcare fees. Unfortunately, it is a genuine challenge to identify those who are indigent. In addition, few studies have assessed the impact of user fees exemption programs on healthcare-seeking behaviour. The majority of indigent people are older with significant health needs. Older people in Africa do not often consult health professionals. The determinants regarding healthcare-seeking behaviour by older people is little-known, although proportionately, their numbers are increasing in low- and middle- income countries. They are losing their autonomy, have little income and have a high prevalence of chronic diseases and functional disabilities. These problems occur early on, especially among women. Objectives  The objectives of this thesis are as follows: (i) to determine the equitable nature of a community-based selection process for indigent people in Burkina Faso that aims to exempt them from paying healthcare user fees; (ii) to measure the impact of this user fees exemption program on healthcare-seeking behaviour among indigent people; (iii) to analyze the factors associated with healthcare-seeking behaviour  by older people in Nigeria. Method  The conceptual framework of this study is based on the model developed by Andersen and Newman, which groups healthcare use determinants into predisposing factors (age, gender, marital status, occupation), enabling factors (income, means and know-how to access financial, food or instrumental assistance, social relationships), and needs (presence of chronic disease and vision, muscle strength and mobility limitations).  To determine the equitable nature of a community-based selection of indigent people, we carried out a cross-sectional study in 2010 in the Ouargaye District of Burkina Faso, in which 1687 indigent people were interviewed. The dependent variable was possession of an exemption card. Bivariate analyses and logistic regression were performed. Next, using a quasi-experimental before/after approach, we assessed the effects of this user fees exemption program on healthcare-seeking behaviour by indigent people in Burkina Faso. To that end, 1224 indigent people were interviewed in 2010 about their healthcare-seeking behaviour. Among them, 540 were selected and received an exemption card. One year later, a follow-up was conducted, with a 55.3% retention rate. Bivariate analyses and logistic regression were performed. Finally, using data from a national cross-sectional study, the Nigerian 2012–2013 General Household Survey, which covers all the country’s regions, we studied healthcare-seeking behaviour by 3587 older people, of whom 850 stated that they were ill. We attempted to identify the associated factors. Weighted bivariate analyses and a weighted Poisson regression were performed. Results  In Burkina Faso, healthcare payment waivers were mainly granted to widows or widowers (OR=1.40 IC 95% [1.10–1.78]), to those who do not receive financial support from their household for healthcare (OR=1.58 IC 95% [1.26–1.97], or those who live alone (OR=1.28 IC 95% [1.01–1.63]), or with their spouse (OR=2.00 IC 95% [1.35-2.96], who have vision impairment (OR=1.45 IC 95% [1.14–1.84]), who have limited muscle strength and good mobility (OR=1.73 IC 95% [1.28–2.33]). The community-based selection process of indigent people is not completely equitable, although it did enable the most needy to be selected. There are gender differences concerning healthcare-seeking behaviour determinants among indigent people. Being a widower (OR=0.53 IC 95% [0.33–0.81]), and having vision impairment (OR=0.42 IC 95% [0.28–0.63]) were factors limiting healthcare-seeking behaviour among men but not among women. Chronic diseases remain a common obstacle among men (OR=4.05 IC 95% [2.84–5.77]) and women (OR=2.14 IC 95% [1.54–2.97]).  User fees exemption is not associated with an increased use of healthcare services (OR=1.1 IC 95% [0.80–1.51]). Whether they received or did not receive exemption cards, indigent people over the age of 69 (OR=1.66 IC 95% [1.05–2.64]), who were male (OR=1.44 IC 95% [0.99–2.08]), who belong to a low-income household (OR=1.71 IC 95% [1.15–2.54]), and those who had financial assistance from family to access healthcare (OR=1.59 IC 95% [1.1–2.28]), are more likely to increase their use of healthcare.  In Nigeria, only 53% of older people consulted a health practitioner after an episode of illness. Lack of education (PR = 0.73, 95% CI [0.60–0.8]), low household income (PR = 0.75, 95% CI [0.5–0.9]), and residence in Nigeria’s South South (PR = 0.59 95% CI [0.4–0.7]) and South West zones (PR = 0.60 95% CI [0.4–0.7]) constituted limitations to consulting a health practitioner.  Conclusion Community-based selection is one method that appears to have made it possible to select indigent people with a high prevalence of health needs and obstacles to seeking healthcare. Healthcare payment waivers are not sufficient to increase their healthcare-seeking behaviour. Healthcare use determinants differ according to gender, but chronic disease constitutes a common theme. Elderly and indigent people have common characteristics, such as advanced age, but some factors that determine their healthcare-seeking behaviour differ. The common determinant is the financial factor, i.e., the contributory capacity of these people in a context where the user pays. Until there is universal healthcare coverage, it would be appropriate to ensure that activities to improve healthcare-seeking behaviour primarily target populations with significant needs, such as indigent and elderly people, by removing financial barriers. For indigent people, however, additional measures must be included, such as accompaniment, transportation and accommodation expenses. And activities must also take existing gender differences into account among the factors determining their healthcare-seeking behaviour.
