Quality assurance of routine data (7/10)
b) Quick introduction to WHO 2017 Data Quality Review (DQR)
The DQR is an Excel-based analytical tool which calculates standard data quality metrics for selected indicators. It examines the quality of data generated by a health facility-based information system for up to six tracer indicators from across program areas. In addition to program areas used for illustration in the tool, the DQR can be also used to assess other program areas indicators, such as Nutrition, by entering appropriate information on the data (indicator) to be assessed.
Through analysis of the six tracer indicators, the tool quantifies problems of data completeness, accuracy and external consistency and thus provides valuable information on the extent to which data are “fit-for-purpose” to support planning and annual monitoring (DQR website).
