Scaling up access to antiretroviral treatment for HIV infection : the impact of decentralization of healthcare delivery in Cameroon

Background: The independent evaluation of the Cameroonian antiretroviral therapy (ART) Programme, which reached one of the highest coverage in the eligible HIV-infected population (58%) in Sub-Saharan Africa, offered the opportunity to assess ART outcomes in the context of the decentralization of HIV care delivery. Materials and methods: A cross-sectional survey (EVAL, ANRS 12-116, 2007) was carried out in a random sample of 3151 HIV-positive patients (response rate 90%) attending 27 treatment centres at the different level of the healthcare delivery (central, provincial and district), as well as in the exhaustive sample of doctors in charge of HIV care in these centres (response rate 92%, n = 97). Multivariate two-level analyses were conducted to assess the impact of the level of healthcare delivery on CD4 cell gains since initiation of treatment and adherence to treatment in the subsample of patients who were ART-treated for 6 months or more (n = 1985). Results: District treatment centres were characterized by more limited technical and human resources but a lower workload. ART-treated patients followed up in these centres had significantly lower socioeconomic status. After adjustment for other explanatory factors, immunological improvement was similar in patients followed up at the central and district level, whereas adherence to ART was better both at provincial and district levels. Conclusion: Success in scaling-up access to ART in Cameroon has been facilitated by decentralization of the healthcare system. Long-term sustainability urgently implies better integration of this HIV-targeted programme in the global healthcare reform of financing mechanisms, management of human resources and drug procurement systems

An assessment of interactions between global health initiatives and country health systems

Since 2000, the emergence of several large disease-specific global health initiatives (GHIs) has changed the way in which international donors provide assistance for public health. Some critics have claimed that these initiatives burden health systems that are already fragile in countries with few resources, whereas others have asserted that weak health systems prevent progress in meeting disease-specific targets. So far, most of the evidence for this debate has been provided by speculation and anecdotes. We use a review and analysis of existing data, and 15 new studies that were submitted to WHO for the purpose of writing this Report to describe the complex nature of the interplay between country health systems and GHIs. We suggest that this Report provides the most detailed compilation of published and emerging evidence so far, and provides a basis for identification of the ways in which GHIs and health systems can interact to mutually reinforce their effects. On the basis of the findings, we make some general recommendations and identify a series of action points for international partners, governments, and other stakeholders that will help ensure that investments in GHIs and country health systems can fulfil their potential to produce comprehensive and lasting results in disease-specific work, and advance the general public health agenda. The target date for achievement of the health-related Millennium Development Goals is drawing close, and the economic downturn threatens to undermine the improvements in health outcomes that have been achieved in the past few years. If adjustments to the interactions between GHIs and country health systems will improve efficiency, equity value for money, and outcomes in global public health, then these opportunities should not be missed
