Optimisation of HIV care and service delivery: doing more with less.

The unprecedented, successful collaborative international effort to provide universal access to HIV care, including effective antiretroviral therapy, has reached a crucial point. Global economic downturn, changing donor priorities, and competing priorities in the health sector threaten the target of provision of 15 million people with HIV/AIDS with treatment by 2015, as agreed by the UN General Assembly. This aspiration has received added impetus from the finding that treatment prevents transmission by reduction of infectiousness of patients. In this report we critically review success thus far and examine efforts to optimise delivery of HIV care including antiretroviral therapy in low-income and middle-income countries for four main domains: treatment strategy, drug dosing, monitoring, and service delivery.
