GNU Health is a Free Health and Hospital Information System that provides the following functionality:

  • Electronic Medical Record (EMR)
  • Hospital Information System (HIS)
  • Health Information System

It is designed to be multi-platform, so it can be installed in different operating systems (Linux, FreeBSD, MS Windows) and different database management systems (PostgreSQL). It's written in Python and uses the Tryton framework.


GNU Health started in 2008 by Luis Falcón as a project for health promotion and disease prevention in rural areas. Its initial name was Medical. It has since evolved into a Health and Hospital Information System, with a multi-disciplinary international team of contributors. GNU Health is a project of GNU Solidario, which is a non-profit non-governmental organization (NGO) that works in the areas of health and education with free software.

Main Development events


GNU Health is intended to run in Health Centers, to take care of the daily clinical practice as well as to manage health center resources.


GNU Health uses a modular approach around the kernel, with different functionality that can be included to meet the health center's needs. The current modules are:

  • Lab: Manages the request, creation and evaluation of laboratory analyses. Interface to Laboratory Information Management System
  • Socioeconomics: Education, occupation, living conditions, hostile areas, child labour and prostitution, among others.
  • Inpatient: Patient Hospitalization, bed assignment, care and nursing plans.
  • Surgery: Pre-operation checklist, procedures, operating rooms, patient surgery history.
