What is defined as the systematic collection, analysis, and interpretation of health data for decision-making?

The systematic collection, analysis, and interpretation of health data for decision-making is best defined as public health surveillance. This process involves monitoring health events and trends in a population to identify outbreaks, evaluate the effectiveness of interventions, and inform public health policies. By systematically gathering and analyzing data, public health surveillance aids in understanding and addressing health issues within a community, guiding effective responses and preventive measures.

In contrast, public health practice encompasses a broader range of activities aimed at improving health outcomes, while healthcare management focuses specifically on the operational aspects of healthcare organizations. Health informatics, on the other hand, is concerned with the management and use of health information systems and technology but does not specifically emphasize the systematic monitoring and interpretation of health data for public health purposes.
