. It is developed by the Health Information Systems Programme (HISP) project.

The solution covers aggregated routine data, semi-permanent data (staffing, equipment, infrastructure, population estimates), survey/audit data, and certain types of case-based on patient-based data (for instance disease notification or patient satisfaction surveys). The system supports the capture of data linked to any level in an organisational hierarchy, any data collection frequency, a high degree of customisation at both the input and output side. It has been translated into a number of languages.

The DHIS was originally developed for three health districts in Cape Town

, where its use covers a population of 300-400 million people, and to a number of countries in Asia. The initial scope - routine monthly Primary Health Center data – has systematically been expanded to cover nearly all aspects of health data and information (excluding electronic health records). Available aggregated data for South Africa from 1998-2007, for instance, represent close to one billion patient encounters.
