Linked data

Linked data is information brought together from different data sources relating to the same individual, family, place or event. Record linkage allows a more complete picture of the health of the population, and can be used for health research, policy development and service planning across the population.

The Centre for Health Record Linkage (CHeReL) securely brings together information from different databases at hospitals, health departments and other organisations providing health care in NSW and the ACT.

Linkage of health-related data needs to be in accordance with all ethical, legal, privacy and confidentiality requirements.
