The Admitted Patient Data Collection


The Admitted Patient Data Collection (formerly Inpatient Statistics Collection) is administered by the NSW Department of Health. The collection contains information about all health services provided on an admitted patient basis by Public Hospitals, Public Psychiatric Hospitals, Multi Purpose Services, Private Hospitals and Private Day Procedure Centres in NSW.

Reporting to this data collection is a requirement under the Health Service Act 1997 for public hospitals, and the Private Health Facilities Act 2007 and Health Insurance Act 1973' for private hospitals.

The purpose of the Admitted Patient Data Collection is to plan health services, track indicators of health status, and provide statistical information to monitor the utilisation and performance of NSW hospital services and to support health research. The information collected includes patient demographics, source of referral to the service, service referred to on separation, and clinical information (diagnoses, procedures, external causes, activities when injured, places of occurrence, and morphologies).

Data are available back to 1993-94. For data availability prior to this, contact NSW Department of Health.


The NSW Admitted Patient Data Collection covers all admitted patient activity provided by Public Hospitals, Public Psychiatric Hospitals, Multi Purpose Services, Private Hospitals and Private Day Procedure Centres in NSW. However, it excludes all services provided on a non-admitted patient basis by these establishments.

The following activity in hospitals is also excluded from the scope of the Admitted Patient Data Collection:

  • Hospital boarders, i.e. people staying at the hospital who are accompanying patients, such as parents of young children
  • Still births
  • Posthumous Organ procurement
  • Community Residential clients
  • Residential Aged Care clients in beds funded directly by the Australian Government, such as Residential Care clients accommodated in Multi Purpose Services


The following is a selection of some of the available data items:
  • Patient demographics
    • Date of birth (age)
    • Sex
    • Country of birth
    • Preferred language
    • Aboriginal and Torres Strait Islander origin
    • Area of usual residence
    • Marital status
  • Admission items, e.g. admission date/time, source of referral, facility transferred from, urgency of admission, health insurance status, Medicare eligibility
  • Admitted patient event items, e.g. start/end date/time, service category (care type), Medical Officer speciality, bed type
  • Separation items, e.g. date/time, facility transferred to, hours in Intensive Care unit, mode of separation
  • Items only for mental health clients, e.g. previous specialised treatment, year last admitted to a designated psychiatric unit, days in designated psychiatric unit, days involuntary under Mental Health Act
  • Clinical information, e.g. procedures, principal and secondary diagnoses, external causes of injury or poisoning, activity when injured, place of occurrence, morphologies, diagnosis related group, major diagnostic category, additional diagnosis
  • Cancer items (required where there is a notifiable cancer diagnosed and active or palliative treatment is provided for each primary cancer), e.g. primary site of cancer, morphology, degree of spread at this episode

Clinical information is coded using the International Statistical Classification of Diseases, using the Australian modification.

The Admitted Patient Data Collection can support reporting one record for each 'stay in hospital' or for each 'episode of care' within that stay in hospital. A 'stay in hospital' begins with the formal admission of the patient, and ends with the formal discharge, transfer or death of the patient. An 'episode of care' is a phase of care within the stay in hospital, including 'Acute', 'Rehabilitation', 'Palliative', 'Maintenance', 'Psychogeriatric' and 'Geriatric Evaluation and Management'.


The Admitted Patient Data Collection is commonly presented by:
  • Area Health Service of the service provider
  • Area Health Service of the patient's usual residence
    Note: Area Health Services are administrative entities with NSW Health, although their boundaries generally follow Statistical Local Area (as per Australian Standard Geographical Classification) boundaries.
  • Statistical Local Area of residence


The main source of published de-identified summary level data is the Australian Institute of Health and Welfare's publication Australia Hospital Statistics. Data are also published in the NSW Chief Health Officers Report.

Access to unit record data is limited due to client privacy issues, however requests for access can be put to the NSW Health Department’s ethics committee.
