The NSW Public Health Act 2010 allows for the Minister for Health to establish public health or disease registers to follow up the care and treatment of patients; for infection control and disease outbreak investigations; disease risk factor monitoring in the population; monitoring the outcomes of population health interventions; and monitoring exposure to chemicals or environmental risk factors.
The Centre for Epidemiology and Evidence establishes and manages a range of ad hoc and ongoing registers. Those ongoing registers based on linked administrative data include the Admitted Patient Emergency Department and Deaths Register (APEDDR), the Communicable Diseases Register (CDR) and the Maternal and Chlld Health Register (MCHR).
