Incentives for Viral Suppression in People Living with HIV: A Randomized Clinical Trial

The HIV/AIDS epidemic can be eliminated if 73% of people living with HIV take antiretroviral medications and achieve undetectable viral loads. This study assessed the effects of financial incentives in suppressing viral load. People living with HIV with detectable viral loads (N = 102) were randomly assigned to Usual Care or Incentive groups. Incentive participants earned up to $10 per day for 2 years for providing blood samples that showed either reduced or undetectable viral loads. This report presents data on the 1st year after random assignment. Incentive participants provided more (adjusted OR = 15.6, CI 4.2-58.8, p < 0.001) blood samples at 3-month assessments with undetectable viral load (72.1%) than usual care control participants (39.0%). We collected most blood samples. The study showed that incentives can substantially increase undetectable viral loads in people living with HIV. Financial incentives for suppressed viral loads could contribute to the eradication of the HIV/AIDS epidemic.
