Sana is a cell phone-facilitated clinical information system that connects community health workers and medical specialists, to improve screening and diagnostics in resource-constrained settings. The platform allows the transmission of any type of medical data—text, audio, video or photo—from a rural health worker to a remote medical specialist for real-time decision support, and for incorporation into an electronic medical record in order to facilitate care, quality control and allow statistical analysis. By functioning as a portable medical record, Sana also offers the ability to track patients more easily. The point-of-care platform is open source and customizable, allowing doctors to encode new assessments onto smart-phones for a specific application, or to use existing ones. It is closely connected with Partners in Health. Developers are needed to extend both the android front end and the back end medical record system for applications in primary care.
