Abstract
Background. Treatments are effective for people living with HIVAIDS (PLWHA) care and prevention. However, only 55% of PLWHA are aware of their status. This rate is lower in Central and West Africa (35%). In July 2015, WHO published new guidelines on HIV testing. In Sub-Saharan Africa, there are many studies which results are used to define policies and guidelines on HIV testing at the international level. Few of them are implemented in low HIV prevalence countries, notably French-Speaking West Africa. The overall objective of this thesis is to analyze the challenges and limitations of HIV testing and counselling (HTC) policies and programs in low prevalence countries, over the situation in Burkina Faso and propose new measures to increase the access to HTC services.Methods. Two studies have been conducted. The first one was carried out in the « Multi-country African Testing and Counselling for HIV » (MATCH) project which was implemented in four countries (Burkina Faso, Kenya, Malawi, Uganda). It aimed to analyze the motivations and barriers to HTC services practices by users, non-users and providers. In Burkina Faso, the study was carried out in Urban (Ouagadougou) and rural (Dédougou) areas in 2008-2009. In each locality, study sites (client initiated testing and provider initiated testing sites) were chosen, given the level of utilization. Quantitative and qualitative methods were used. The second study was conducted in 2015, with HTC providers and decision makers at national level. The objective was to analyze their perceptions on WHO 2015 guidelines. A data collection tool explaining the changes introduced in the guidelines has been designed and transmitted via electronic means. Their opinions were analyzed.Results. Guidelines for HTC in Burkina Faso were from 2008. In client initiated testing sites, there were more women (58.5%). However, men (p=0.02), 18-34 years old (p=0.01), and the more educated ones (p=0.001) appeared to have used early services. In multivariate analysis, those categories used often campaigns. Women (p=0.008), 35 years of age and over (p<0.001) and less educated people (p<0.001) sought more often the test in fixed sites. The use of HTC services during campaigns is associated with the desire to know one's HIV status (p<0.01), while outside of campaigns, the health status of the user, the illness or the partner's death was the main concern (p=0.001). Campaigns are associated with the hope of knowing one’s HIV status (p<0.001). There were 61% of users who were repeat testers (2 or more tests). In a multivariate analysis, repeat testing for HIV negative people was associated with higher education, young age and for PLWHA living in urban areas. HTC Providers declared that they faced logistic and material challenges. It resulted in a low quality of services, in particular post-test counselling sessions that were partially done and a low effective reference of PLWHA towards care services. HIV stigma was found to be very high (46% of PLWHA faced internal stigma, 40% of interpersonal stigma, and 11% in health services). Decision-makers and providers have found most of the 2015 guidelines relevant, but were pessimist about their feasibility.Conclusion. This work has identified limitations of HTC at the individual, community, health services and institutional levels in Burkina Faso, and provides significant elements for African low prevalence countries. Given the scarcity of resources, there is a need for innovative strategies for equitable access to HTC, in order to attract more men, and test earlier women, less educated and 34 years or older. Strengthening the capacity of service providers to include a comprehensive range of quality services is necessary. All the aforementioned should be supplemented by the fight against stigma. Paying attention to national HTC experts’ opinion will help for national guidelines review and adapt them to WHO guidelines.
