Purpose / Aims: The Bariatric Surgery Registry is a population-based observational quality improvement study of persons with obesity who have bariatric surgery. Within the remit of a clinical quality registry, its purpose is to gather and analyse information that is used to monitor and enhance the quality of care received by obese persons undergoing bariatric surgery in Australia and New Zealand. This includes the safety, efficacy and standards of bariatric surgery.

The Bariatric Surgery Registry does this by:
  • recording the immediate safety of bariatric surgery in Australia and New Zealand by determining any events in the first 90 days post-surgery
  • studying longitudinally the safety and efficacy of bariatric surgery in Australia and New Zealand
  • continuous validation of data through thorough quality checks to ensure all data is accurate and true in its representation
  • providing regular feedback to clinicians, allowing them to measure their performance against validated and quality checked reports
Population Captured: The Registry collects data about persons with obesity undergoing bariatric surgery in private and public hospitals across Australia and New Zealand.
Outcomes Collected: Clinical quality indicators (termed defined adverse events) within the 3 month period post operatively include:
  • unplanned return to theatre
  • unplanned ICU admission
  • unplanned readmission to hospital
  • mortality

The incidence of adverse events and deaths related to bariatric surgery are monitored for all participants. Clinical outcome measures in primary participants include:

  • weight/BMI changes
  • change in diabetes status
  • change in diabetes treatment over time
  • the need for revision surgery
  • the effect on lifespan

The Registry aims to capture the clinical outcome measures on an annual basis for a period of up to 10 years for all primary participants.
