Sound and reliable information is the foundation of decision-making across all health system building blocks.
It is essential for health system policy development and implementation, governance and regulation, health
research, human resources development, health education and training, service delivery and financing.
The health information system provides the underpinnings for decision-making and has four key functions:
(i) data generation, (ii) compilation, (iii) analysis and synthesis, and (iv) communication and use. The health
information system collects data from health and other relevant sectors, analyses the data and ensures their
overall quality, relevance and timeliness, and converts the data into information for health-related decisionmaking
