National profile of early warning indicators of HIV pharmaco-resistance in Cameroon

since the launch of the "Treatment for All in Cameroon" strategy in 2015, an acceleration plan for antiretroviral (ARV) therapy in Cameroon was implemented, with remarkable progresses. These efforts were accompanied by the risk of developing HIV drug resistance. Then, the World Health Organization (WHO) proposed surveillance of early warning indicators (IAP) for HIV drug resistance. The purpose of this study was to assess the national HIV Drug Resistance Early Warning Indicators (EWI) in Cameroon. we conducted a retrospective study in the ten regions of Cameroon in December 2017 to evaluate the six EWIs recommended by the WHO in 68 randomly selected HIV care sites. The reporting period ranged from July 2016 to June 2017. national scores were: drug withdrawal within the estimated time frame (EWI1): 66%; retention on antiretroviral therapy 12 months after treatment initiation (EWI2): 66%; stock-out of antiretroviral drugs over a 12-month period (EWI3): 53%; viral load testing coverage (CV) (EWI4): 10%; coverage suppression after 12 months of antiretroviral therapy (EWI5): 73% and practices for ARV drug delivery (EWI6): (100%). Regional scores were similar. the evaluation of EWI in Cameroon is limited and requires urgent interventions, primarily viral load testing coverage, optimal ARVs management and patient´s adherence.
