What are National Registries?
National registries are systematic collections of data about individuals, usually focused on specific diseases, conditions, or exposures. These registries play a critical role in
epidemiology by providing a comprehensive source of information that can be used for
public health surveillance, research, and policy development.
Purpose and Benefits
The primary purpose of national registries is to monitor the incidence and prevalence of diseases, understand their
risk factors, and evaluate the effectiveness of interventions. Benefits include:
Types of National Registries
There are various types of national registries, including:
