Collection and usage attributes
Unplanned/unexpected readmissions are those readmissions where the principal diagnosis indicates an adverse event.
Principal diagnoses codes
A principal diagnosis for the readmission has one of the following ICD-10-AM (7th Ed) codes: T80–88, T98.3, 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; appendicectomy.
The following is a list of the specific ACHI (7th Ed) 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 service.
Analysis by remoteness and Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socioeconomic Disadvantage (IRSD) is based on usual residence of person.
Presented per 1,000 separations.

Most recent data available for 2015 National Healthcare Agreement (NHA) performance reporting: 2012–13.
The scope of the National Hospital Morbidity Database (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 2011-12 data, the 2011 SEIFA IRSD quintile and decile data were produced using the Australian Standard Geography Classification geographical unit of Statistical Local Area. For 2012–13 data, the 2011 SEIFA IRSD quintile and decile data will be produced using the Australian Statistical Geography Standard geographical unit of Statistical Area 2.
The title of this indicator was changed in the 2012 NHISSC specifications from Unplanned/unexpected readmissions within 28 days of selected surgical admissions to Unplanned/unexpected readmissions within 28 days of selected surgical episodes of care to better reflect how the indicator is calculated. Readmissions for this indicator are defined within 28 days from the end of the patient’s surgical episode of care.
