D-tree International has developed mobile-based decision-making tools for use in low and middle-income countries for a variety of health services including maternal health, child health, chronic and infectious diseases, and health systems strengthening. D-tree was initially tested for effectiveness in Tanzania.1 A partnership between FHI 360, Pathfinder International, and D-tree International in collaboration with the Tanzanian Ministry of Health and Social Welfare initiated a mobile job aid intervention for improved contraceptive counseling in Tanzania in 2011. Prior to implementation, community health workers (CHWs) used paper forms and flip charts for contraceptive counseling in communities. This was physically challenging and led to unnecessarily long data collection and transfer. The mobile job aid included three components: 1) a decision-support tool for CHWs to use during counseling, screening, and referrals; 2) electronic data collection to record services and referrals, and 3) a SMS tool to record and send CHW status reports and remind CHWs of follow-ups. While the use of this job aid was shown to be feasible, patient use of contraceptives was still dependent on the CHW’s knowledge, patient readiness, and availability of methods, suggesting that a job aid can provide the most utility when paired with effective training and inputs.
