Mobile phone access in low and middle-income countries is rapidly expanding and offers an opportunity to leverage limited human resources for health. We conducted a mixed methods evaluation of a cluster-randomized trial exploratory substudy on the impact of a mHealth (mobile phone) support intervention used by community-based peer health workers (PHW) on AIDS care in rural Uganda. 29 PHWs at 10 clinics were randomized by clinic to receive the intervention or not. PHWs used phones to call and text higher level providers with patient-specific clinical information. 970 patients cared for by the PHWs were followed over a 26 month period. No significant differences were found in patients’ risk of virologic failure. Qualitative analyses found improvements in patient care and logistics and broad support for the mHealth intervention among patients, clinic staff, and PHWs. Key challenges identified included variable patient phone access, privacy concerns, and phone maintenance. 

Two challenges to successful antiretroviral therapy (ART) scale-up in resource-limited settings (RLS) are human resource and healthcare infrastructure limitations. 

We read with interest the modeling study by Bärnighausen et al. which describes the complexities of ensuring adequate human resources to treat HIV/AIDS (HRHA). The authors suggest that factors needed to achieve universal ART coverage include “changes in the nature or organization of care,” training health workers with skills specific to the developing world to reduce emigration, and developing systems that decrease the number of traditional HRHA required to treat a fixed number of patients.

The Rakai Health Sciences Program (RHSP) PEPFAR-funded ART program has been actively pursuing innovative HIV care strategies that directly address these important points. In 2006, we piloted a novel program utilizing peer health workers (PHW) and mobile phones to monitor patients in a rural ART program in Rakai, Uganda.

In this paper, we present a phone-based application called CommCare which supports community health workers (CHWs) as they provide home-based care and social support to HIV+ and other chronic patients. We report on our experience developing and testing the application with five CHWs in Dar es salaam, Tanzania. We have developed a simple and easily useable system by rapidly prototyping CommCare with the community health workers, in quick iterations based on their feedback. The system guides the user through about 15 questions during each household visit. The CHWs answer the questions using the phone’s number pad, and the results are submitted over the cellular network to our server when the session is over.

We report on lessons learned from training and our initial deployment. We discuss the few hardware and software problems that arose during our initial piloting, most of which have been addressed. This use of CommCare has little effect on the time or efficiency of home visits, but results in much easier, much faster, and potentially more accurate reporting. In particular, it saves the CHWs approximately four hours per month spent on compiling reports in the paper system.

Finally, we conducted an initial qualitative assessment of the perception of the phone-based system by the clients of the CHWs who used it. We report on the findings below, which generally show a favorable impression of the system, including an appreciation that a phone can be more discreet than paper notebooks and that it can report data more quickly.
