Collection and usage attributes
Unplanned/unexpected hospital readmissions are those readmissions where the principal diagnosis indicates an adverse event.

A principal diagnosis for the readmission has one of the following ICD-10-AM (10th edn.) codes: T80–T88, E89, G97, H59, H95, I97, J95, K91, M96 or N99.
Number of separations in which one of the following surgical procedures was undertaken: knee replacement, hip replacement, tonsillectomy and adenoidectomy, hysterectomy, prostatectomy, cataract surgery, or appendicectomy.
The following is a list of the specific Australian Classification of Health Interventions (10th edn) procedure codes which are included in the specifications for each of the selected surgical procedures.
Limited to public hospitals.
Denominator limited to separations with a separation date between 1 July and 19 May in the reference year.
Denominator excludes separations where the patient died in hospital.
Analysis by state and territory is based on location of the service.
Analysis by remoteness and Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socio-Economic Disadvantage (IRSD) is based on usual residence of the person.
Presented per 1,000 separations.
1,000 x (Numerator ÷ Denominator)
Calculated separately for each of the specified procedures
Number of separations for public hospitals which meet all of the following criteria:
|Numerator data elements:|
Number of separations in which one of the following surgical procedures was undertaken: knee replacement, hip replacement, tonsillectomy and adenoidectomy, hysterectomy, prostatectomy, cataract surgery, appendicectomy.
|Denominator data elements:|
2018–19—Nationally, by specified procedures, by:
2018–19—State and territory, by specified procedures.
Disaggregation by peer group used the peer group classification as described in the AIHW publication Australian hospital peer groups.
Some disaggregations may result in numbers too small for publication.
|Disaggregation data elements:|
Most recent data available for 2021 National Healthcare Agreement performance reporting: 2018–19.
The scope of the NHMD is episodes of care for admitted patients in essentially all hospitals in Australia, including public and private acute and psychiatric hospitals, free-standing day hospital facilities, alcohol and drug treatment hospitals and dental hospitals.
For 2018–19 data, the 2016 SEIFA IRSD quintile and decile data will be produced using the Australian Statistical Geography Standard 2016 geographical unit of Statistical Area Level 2.
Note that for the 2016 and previous reports, disaggregations by public hospital peer group for this indicator were calculated using the peer group classification method as reported in Australian hospital statistics 2010–11.
