Decentralization of access to antiretroviral therapy in Cameroon: correlates of HIV physicians' knowledge in HIV care.

Background: Good knowledge in HIV care among physicians is a necessary prerequisite to effective antiretroviral therapy (ART) scaling-up in Sub-Saharan Africa.

Methods: Between September 2006 and March 2007, a 27-item knowledge questionnaire was proposed to all HIV physicians working in 27 hospitals throughout six provinces of Cameroon. Physicians' responses were compared between the three levels of decentralization of the Cameroonian healthcare delivery system (χ(2) and Fisher tests).
