The WHO Data Quality Review Toolkit, a methodology for assesing the quality of routine health information system data, applies a framework that examines four dimensions of routine data quality – completeness and timeliness of data, internal consistency of reported data, external consistency of routine data with other sources and external comparisons of population data –  and includes supporting analytical tools in Excel and DHIS-2 app formats.


NEP teams in Malawi, Mali and Tanzania used an adaptation of these tools when incorporating DHIS-2 data in their analyses.  NEP developed Stats Report data visualization functions to report findings from data verification activities carried out in health centres.
