2.1 Colonoscopy hospitalisations, all ages

The Third Australian Atlas of Healthcare Variation 2018 investigates healthcare use in four clinical areas. Colonoscopy hospitalisations are included in Chapter 2 on gastrointestinal investigations and treatments.

Why is this important?

Most colonoscopies are performed to detect bowel cancer. Australia’s National Bowel Cancer Screening Program recommends colonoscopy for those people who have a positive faecal occult blood test. Guidelines for bowel cancer screening and surveillance provide evidence-based recommendations on the timing of colonoscopy for people who are at higher risk of bowel cancer. Other indications for colonoscopy include detection and assessment of inflammatory bowel disease. Australian data show that there is substantial overuse of colonoscopy in some parts of the population and underuse in others. This exposes some people to unnecessary risk from the procedure and others to potential harm because a needed procedure was not performed. It is a poor use of resources.

About the data

About the data - Colonoscopy hospitalisations, all ages

Data are sourced from the NHMD, and include admitted patients in both public and private hospitals. Rates are based on the number of hospitalisations for colonoscopy per 100,000 people of all ages in 2016–17.

Because a record is included for each hospitalisation for the procedure rather than for each patient, patients hospitalised for the procedure more than once in the financial year will be counted more than once.

The analysis and maps are based on the residential address of the patient and not the location of the hospital.

Rates are age and sex standardised to allow comparisons between populations with different age and sex structures.
