MEASURE Evaluation has developed tools and concepts for health information system (HIS) measurement in Phase IV. Strengthening an HIS is accomplished through assessment, identification, planning, implementation, and monitoring and evaluation of interventions based on the current state and context. Measurement requires a baseline assessment and monitoring of key indicators to evaluate specific HIS interventions. MEASURE is developing a catalog of HIS assessment and monitoring tools to be available in May 2017, which are cataloged by purpose, method, sampling, timing, level of health system assessed, and areas of the Health Information System Strengthening Model assessed. Examples of tools mentioned are PRISM, RAT, DQR, and MECAT.
