Our research team reached an important milestone in May with the launch of an integrated mHealth system as part of our research study on the effectiveness of short-term cash assistance for people starting HIV treatment. Built by Rasello CS, the system was launched at four clinics in Shinyanga, Tanzania and includes a biometric patient tracking system, automatic delivery of cash transfers through all major mobile money providers (e.g., M-PESA), and collection of survey data. In a major departure from the paper- and cash-based methods of past research studies, when patients attend clinic visits for HIV care they now scan their fingerprint in the pharmacy and information about the visit date, antiretroviral therapy dispensing, and their next visit is digitally captured. Not only does this improve the accuracy of measures of retention in care and adherence, but it reduces the amount of missing data and ensures that patients receive cash transfers within 24 hours to their chosen mobile money account. Perhaps the most exciting feature is that it provides us with real-time data about patient behavior which can be used to improve the clinic experience and the effectiveness of our supportive programs.
