Health Information Systems
In concept, health information system (HIS) is a system for the collection/processing of data from various sources, and using the information for policy making and management of health services. It could be paper-based or electronic. To apply this to a nation, a country HIS integrates data from civil/vital registration, censuses, population surveys, facility surveys, individual records, service records and resource records for policy making and efficient management of health services. There is general agreement among all that a strong HIS is a key component of any health system. However, currently the data sources are often incomplete and fragmented. The challenge is to bring together or integrate all these diverse data sources into one seamless system.
