7.2 Surveillance Objectives in the Public Health Sector

Surveillance is defined as the “ongoing, systematic collection, analysis, perception, and transmission of knowledge about a health-related event for use in public health interventions to reduce the morbidity and mortality and promote health” in the community context of healthcare.

One of the most critical aspects of surveillance is that it must be structured. Furthermore, there is little point in conducting surveillance if the data and results are not used.

The specific objectives of surveillance may vary depending on who is conducting it and the population being studied, but they may include any or all of the following: determining infectious diseases or changes in emerging diseases, determining risk factors for or the natural course of serious diseases, measuring compliance with existing standards, and assessing the effect(s) of practice changes, new initiatives, or digital innovations.
