Short name:Percentage of people who waited longer than the clinical urgency category time for surgery for malignant bowel, breast or lung cancer, 2011-12
METeOR identifier:530408
Registration status:National Health Performance Authority (retired), Retired 01/07/2016
Description:

The percentage of hospital separations involving urgent or semi-urgent surgery for malignant bowel, breast or lung cancer for patients who:

  • were on an elective surgery waiting list for that surgery and
  • waited longer than their clinical urgency category time for surgery:
    • Urgent - longer than 30 days

Computation description:

The percentage of hospital separations involving urgent or semi-urgent surgery for malignant bowel, breast or lung cancer for patients who:

  • were on an elective surgery waiting list for that surgery and
  • waited longer than their clinical urgency category time for surgery:
    • Urgent - longer than 30 days

Computation:

100 x (Numerator ÷ Denominator)

Numerator:

Number of hospital separations involving urgent or semi-urgent surgery for malignant bowel, breast or lung cancer for patients who:

  • were on an elective surgery waiting list for that surgery and
  • waited longer than their clinical urgency category time for surgery:
    • Urgent - longer than 30 days
    • Semi-urgent - longer than 90 days.

Calculated using hospital separations with:

  • ICD-10-AM (7th edn) principle diagnosis codes:
    • Bowel cancer - C18, C19 and C20
    • Breast cancer - C50
    • Lung cancer - C34

  • Elective surgery waiting list episode- clinical urgency code:
    1. Admission within 30 days desirable for a condition that has the potential to deteriorate quickly to the point that it may become and emergency
    2. Admission within 90 days desirable for a condition causing some pain, dysfunction or disability but which is not likely to deteriorate quickly or become an emergency
  • Elective surgery waiting list episode—reason for removal from a waiting list:
    1. Admitted as an elective patient for awaited procedure by or on behalf of this hospital or the state/territory
    2. Admitted as emergency patient for awaited procedure by or on behalf of this hospital or the state/territory 

Calculations exclude people who were on an elective surgery waiting list but were transferred to another hospital's elective surgery waiting list, were treated elsewhere but not on behalf of the hospital, were not contactable, died prior to receiving their surgery or declined surgery.

Comments:

Reported for hospitals with 10 or more separations in the cohort.

Values are rounded up to the nearest whole number.

The waiting times are those experienced by people who have received their surgery and are not the waiting times for those patients who are waiting for surgery.

For this indicator malignant refers to those cancers that have the ability to progress to more serious disease and spread to surrounding tissue or other organs, if left untreated.

Accountability attributes

Other issues caveats:

Waiting times are 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 any not ready for care days that occurred while the patient was listed with the urgency category at removal.


There are inconsistencies in application of urgency categories between and within states and territories which impact on the comparability of results.
