Computation description:Help on this term

Elective surgery as defined in the National Elective Surgery Waiting Times Data Collection.

For 2015–16, indicator procedure as defined in Elective surgery waiting list episode—indicator procedure, code NN.

For 2016–17, indicator procedure as defined in domain values 001 to 017 in Elective surgery waiting list episode—intended procedure, code NNN.

Waiting time as defined in Waiting time at removal from elective surgery waiting list. Calculated by jurisdictions by subtracting the listing date for care from the removal date, minus any days the patient was waiting with a less urgent clinical urgency category than their clinical urgency category at removal, and excluding days where the patient was not ready for care.

Waiting times are calculated for patients whose reason for removal was:

  1. Admitted as an elective patient for awaited procedure by or on behalf of this hospital or the state/territory.
  2. Admitted as an emergency patient for awaited procedure by or on behalf of this hospital or the state/territory.

Analysis by state and territory based on location of 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 as number of days.

Computation:Help on this term

Number of days waited at 50th and 90th percentile.

Calculated overall and for each indicator procedure.

The 50th and 90th percentiles have been rounded to the nearest whole number of days.

The calculation is where:

n is the number of observations and

p is the percentile value divided by 100,

then n × p = i + f (where i is an integer and f is the fractional part of n × p).

If n × p is an integer, the percentile value will correspond to the average of the values for the ith and (i+1)th observations.

If n × p is not an integer, the percentile value will correspond to the value for the (i+1)th observation.

Disaggregation:Help on this term

2015–16 (revised following jurisdiction provision of elective surgery waiting times cluster data to the National Hospital Morbidity Database (NHMD)), 2016–17—State and territory, by indicator procedure (and total), by:

  • peer group
  • Indigenous status

2015–16 (revised following jurisdiction provision of elective surgery waiting times cluster data to the NHMD)—State and territory, by:

  • remoteness (Australian Statistical Geography Standard (ASGS) Remoteness Structure)
  • 2011 SEIFA IRSD quintiles

2015–16 (revised following jurisdiction provision of elective surgery waiting times cluster data to the NHMD)—Nationally, by (all not reported):

  • 2011 SEIFA IRSD deciles
  • selected indicator procedures (cataract extraction, cholecystectomy, coronary artery bypass graft, cystoscopy) by 2011 SEIFA IRSD quintiles
  • indicator procedure, by peer group, by Indigenous status, by remoteness (ASGS Remoteness Structure).

Some disaggregations may result in numbers too small for publication.

Disaggregation by peer group uses the peer group classification as described in the AIHW publication Australian hospital peer groups.

Comments:Help on this term

Most recent data available for 2018 National Healthcare Agreement performance reporting: 2016–17.

Indicator procedures are a subset of all procedures, e.g. in 2007–08, approximately 65% of removals did not fall into one of the defined indicator procedures.

For 2015–16 data, the 2011 SEIFA IRSD quintile and decile data will be produced using the Australian Statistical Geography Standard geographical unit of Statistical Area Level 2.

The scope of the National Elective Surgery Waiting Times Data Collection is patients on, or removed from, waiting lists for elective surgery which are managed by public acute hospitals.

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.
