Which option correctly lists the four functions of health information systems?

• A. Data generation, compilation, analysis, synthesis
• B. Data generation, compilation, analysis, storage
• C. Data generation, processing, analysis, synthesis
• D. Data generation, compilation, validation, synthesis

Answer: (A)

Health information systems are designed to turn raw data into usable knowledge that supports decisions in care and policy. The four functions here capture that progression: data generation creates the raw information from sources like clinics, laboratories, and surveys; compilation brings that data together into organized datasets; analysis applies methods to interpret the data and uncover patterns; synthesis then integrates those findings into actionable insights, summaries, and recommendations for decision makers. This sequence—generate, compile, analyze, synthesize—shows how data become information and information becomes knowledge that can guide improvements in health outcomes, resource use, and program planning. The other options mix in terms that emphasize storage, a broad notion like processing, or data quality checks, which are important but don’t align with the four-step flow that ends in synthesizing knowledge for action.
