Different delivery models for antiretroviral therapy in sub-Saharan Africa in the context of 'universal access'

Abstract

In 10 years, in line with the concept of universal access, 25 million HIV-infected patients in sub-Saharan Africa might be on antiretroviral therapy (ART). There are different models of ART delivery, from the individualised, medical approach to the simple, public health approach, both having distinct advantages and disadvantages. This mini-review highlights the essential components of both models and argues that, whatever the mix of different models in a country, both must be underpinned by similar core principles so that uninterrupted drug supplies, patient adherence to therapy and compliance with follow up are assured. Failure to do otherwise is to court disaster.
