A targeted approach for routine viral load monitoring in Malawian adults on antiretroviral therapy.

ABSTRACT: OBJECTIVES:WHO recommends HIV viral load (VL) testing 6 months after antiretroviral therapy (ART) initiation and every 12 months thereafter, but cost prohibits routine, universal VL testing in many developing countries. We sought to devise a targeted approach to routine VL monitoring that could reduce cost and identify those at low risk for virologic failure (VF). METHODS:We analysed screening data from a clinical trial enrolling adults on ART in Malawi. We identified risk factors associated with VF and employed the Knill-Jones method to assign summary score identifying persons at lower risk for VF. RESULTS:Among 957 adults, prevalence of VF was 9.4%. Factors independently associated with VF included age <38 years (OR 3.44, 95% CI 2.01-5.89), ART duration >2.5 years (OR 2.98, 95% CI 1.79-4
