In this paper, we present D-tree International’s work with medical algorithms and mobile applications to improve the standards of care in clinical and community settings. In particular, we present a mobile phone-based application called CommCare which helps community health workers (CHWs) to provide home-based care and social support to HIV, tuberculosis and other chronic patients. The application guides the CHWs through a series of questions which they answer using the phone’s number pad. The data then can be submitted directly to a central database over a cellular GPRS network.

We report on our experience developing and testing the application in Tanzania, including the iterative development process with the CHWs and training them to use the program. We include an account of some of the hardware and software issues encountered and resolved during the process, and some initial reactions from the first CHWs and clients to use the program. While the formal evaluation of the program is still in progress, initial findings show that the phonebased system is generally viewed positively by the users and by the clients as more discreet and better for privacy than the paper-based system.

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.
