Computation:100,000 x (Numerator ÷ Denominator)
Numerator:

Number of potentially preventable hospitalisations, divided into three groups and total:

  • vaccine-preventable conditions (e.g. tetanus, measles, mumps, rubella).
  • acute conditions (e.g. ear, nose and throat infections, perforated/bleeding ulcer, pelvic inflammatory disease) (excluding dehydration and gastroenteritis).
  • chronic conditions (e.g. diabetes (principal diagnoses only), asthma, angina, hypertension, congestive heart failure and chronic obstructive pulmonary disease).
  • all potentially preventable hospitalisations.

Some disaggregation may result in numbers too small for publication. National disaggregation by Indigenous status will be based on data only from jurisdictions for which the quality of Indigenous identification is considered acceptable.

Comments:

Most recent data available for 2014 Council of Australian Governments (COAG) Reform Council (CRC) report: 2011–12.

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.

Potentially preventable hospitalisations are called ‘ambulatory care sensitive hospitalisations’ in some jurisdictions.

For 2011-12 data, the 2011 SEIFA IRSD quintile and decile data will be produced using the Australian Standard Geography Classification geographical unit of Statistical Local Area.  In future years, these data will be produced using the Australian Statistical Geography Standard geographical unit of Statistical Area 2.

Note that updated ERP by Indigenous status is not available for this cycle.  Data by Indigenous status is calculated using ERP determined prior to the final rebased ERP provided after the 2011 Census.  It is expected that final rebased ERP by Indigenous status will be available for the next cycle of reporting.

Note that the measure being provided this cycle is equivalent to measure 2 (supplementary measure (a)) from the previous cycle.
