NSW Health publishes a range of data from different sources. Sources of data collected and used by NSW Health include administrative data (such as emergency department and hospital data), registry data (such as deaths data), surveys data and programs 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.
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.
