Data information pyramid

Data information pyramid

A schematic way of looking at the number of data items to be collected at each level of the health system allowing each level to gather data of importance and relevance to their daily work while avoiding excessive data collection where no action is taken. The pyramid illustrates how most data are collected at the base of the pyramid in the health facility, where most health service action takes place. Data are processed, filtered, and streamlined as data sets that are then passed up the health system (38).
