Identifying and definitional attributes

Metadata item type:Indicator
Indicator type:Indicator
Short name:PI 03-Hospitalisation rates by principal diagnosis, 2011
METeOR identifier:425741
Registration status:Indigenous, Archived 01/07/2012
Description:Hospital separation rates for leading principal diagnoses for Australians, by Indigenous status.
Rationale:Monitoring hospitalisation rates for different diseases so that it is understood which diseases are major contributors to morbidity among Indigenous Australians and where programs are succeeding and where they are not will assist in achieving the closing the gap targets.

Collection and usage attributes

Computation description:

Crude rates are calculated for Indigenous Australians; age-standardised rates are calculated for Indigenous and non-Indigenous Australians.

Rate ratios and rate differences are calculated for Indigenous:non-Indigenous.

Presentation: Per 1,000 persons; percentage; and causes listed from highest to lowest percentage.

Definitions:

Leading principal diagnoses (and ICD-10-AM codes) are: 

  • Injury and poisoning and certain other consequences of external causes (S00-T98)
  • Diseases of the respiratory system (J00-J99)
  • Diseases of the digestive system (K00-K93)
  • Pregnancy, childbirth and the puerperium (O00-O99)
  • Diseases of the circulatory system (I00-I99)
  • Symptoms, signs and abnormal clinical and laboratory findings (R00-R99)
  • Mental and behavioural disorders (F00-F99)
  • Endocrine, nutritional and metabolic diseases (E00-E90)
  • Diseases of the genitourinary system (N00-N99)
  • Diseases of the skin and subcutaneous tissue (L00-L99)
  • Certain infectious and parasitic diseases (A00-B99)
  • Other
  • Total (excluding care involving dialysis)
  • Care involving dialysis (Z49)
  • Total.
Computation:

Crude percentage: number of separations by principal diagnosis divided by total separations.

Rate: 1,000 x (Numerator ÷ Denominator).

Numerator:Number of hospital separations (public and private).

Disaggregation:

For Indigenous only (crude rates):

  • State and Territory by leading cause of death (ICD-10 chapter level and some sub-chapter level).
  • National by sex and leading cause of death (ICD-10 chapter level and some sub-chapter level).
  • National by sex by excess deaths (ICD-10 chapter level and some sub-chapter level).

For Indigenous and non-Indigenous (age standardised rates):

  • State and territory by leading cause of death (ICD-10 chapter level and some sub-chapter level).
  • National by sex by leading cause of death (ICD-10 chapter level and some sub-chapter level).

Comments:

Most recent data available for 2011 CRC report is 2008-09.

National disaggregation by Indigenous status will be based on data only from jurisdictions for which the quality of Indigenous identification is considered acceptable.

At this stage, only data from selected state/territories are considered of acceptable quality for reporting hospitalisations of Indigenous persons: NSW, Vic, Qld, WA, SA & NT public hospitals. Tas/ACT data should be reported with caveats. National rates should include these six states and territories only.

Rates are directly age standardised to the 2001 Australian ERP.

National estimates adjusted for under-identification will be reported for leading principal diagnoses.

Disaggregation by Indigenous status is to be reported using 2 years combined data for the current reporting period. Single year data is to be reported for time series.

Baseline year for this indicator is 2006; target year is 2031.
