Change of treatment guidelines and evolution of ART initiation in rural South Africa: data of a large HIV care and treatment programme

While WHO recommendations are to treat people earlier and earlier, it will considerably increase the number of HIV infected people eligible for antiretroviral therapy (ART). In South Africa, a country which carries one of the highest HIV burden worldwide, very few studies are available on the impact of the ART guidelines on time to ART initiation in both individuals with low CD4 count and those newly eligible for ART. We thus aimed to describe ART initiation percentages in a large HIV programme in rural KwaZulu-Natal, South Africa, according to the temporal changes of national ART eligibility guidelines from 2007 to 2012. Adults who accessed the decentralized Hlabisa HIV treatment programme in 2007-2012 were included. Three periods following the temporal change of ART eligibility guidelines were defined (Period 1: until April 2010; Period 2: April 2010 - July 2011; Period 3: from August 2011). Percentages of ART initiation within three months of programme entry were estimated in men, in women of childbearing age (
