A national HIS is a growing organism which needs to be maintained. As the system usage increases more requirements and needs will emerge from new and existing stakeholders such as district record officers and health program staff. Regular review meetings including such stakeholders should take place where data capture tools, such as data elements and forms, and data analysis tools, such as indicators and reports, should be revised and new tools potentially added. Also, new functionality requirements should be managed and appropriate software development resources should be secured. Such regular activities for supporting the extension and enhancement of the system are vital to maintain the current momentum and learning processes and to improve long-term project sustainability.
