Continuing provider development through in-service training is an important component of any health sector improvement plan, but traditional residential courses, which take clinicians away from their patients, can disrupt the provision of care and are an expensive method of maintainingan educated workforce. Under-resourced libraries, the high cost of medical journals relative to health budgets and health professionals' incomes, and poor infrastructure for disseminating current medical information and Department of Health directives limit the ability of health professionals to provide quality primary health care. Using smartphones and tablets, practitioners access a mobile health library comprising South African treatment guidelines, drug formularies, diagnostic tools and other evidence-based content, at the point of care. They download clinical and public health information to mobile devices using a mobile library portal developed by FHI 360.
