This document describes an urban e-health pilot project in Santa Marta, Rio de Janeiro that aimed to address barriers to healthcare access using portable electronic health technology. The project found that the e-health backpacks enabled nurses to perform in-home visits and detect chronic diseases earlier, reducing healthcare costs and hospitalizations. Patients and health workers largely reported positive experiences with the backpacks. The results supported the value of using mobile health innovations to improve care for underserved communities.
