Public health and health care are important issues for developing countries and access to health care is a significant factor that contributes to a healthy population. In response to these issues, the World Health Organization (WHO) has been working on the development of methods and models for measuring physical accessibility to health care using several layers of information integrated in a GIS. This paper describes the methodological approach for the development of a real time electronic health record, based on the statistical and geographic information for the identification of various diseases and accidents that can happen in a specific place.
