Mobile Self-verification and Support for Successful Tuberculosis Treatment

Abstract
Successful Tuberculosis (TB) treatment is critical for reducing transmission and lowering treatment costs. Mobile health interventions incorporating behavioral insights promise to increase treatment success, but have largely fallen short of expectations. We developed a costeffective mobile health intervention involving daily self-verification of medication adherence alongside support and motivation, based on proven behavioral insights. We tested whether it improved treatment outcomes in a randomized control trial involving 1189 TB patients in Nairobi, Kenya. Our intervention led to an estimated 7.8% increase in successful treatment. The intervention increased treatment success more for individuals predisposed to treatment failure as estimated by a model fit to the control group (e.g., slum dwellers, the unemployed). We detail the key behavioral insights employed and their adaptation to the particulars of this setting.
