What is Data Linkage?

What is data linkage?

Data linkage, in simple terms, is a method of bringing together information about people, places and events in a way that protects individual privacy. Using specially developed technology, PHRN nodes link existing information from different health and health related data collections to provide data to approved researchers for a range of population-based studies.

Is it all about health?

Historically, research based on linked data has been used in the health sector to examine a range of health issues and provide us with a picture of the health and well-being of our community. The results from these studies have provided valuable information on the causes of and risk factors for disease, the evaluation of new approaches to prevention, early intervention and treatment, and the assessment of new and more effective ways of delivering health services.

More recently, health data has been linked to data from other areas including education, criminal justice and child protection, providing new insights into factors that can influence the health and well-being of the population.
