Mobile health (mHealth) technologies can help community health workers (CHWs) improve their performance through data-driven management. mHealth systems collect data on CHW activities and client outcomes that supervisors can use for supportive supervision, feedback, and incentives to motivate high performance. Successful mHealth requires organizational changes, technical support, training, and scaling capabilities to fully utilize data and sustain results over time. A maturity model outlines five stages programs progress through to maximize mHealth's impact from initial demonstrations to integrated, long-term solutions.
