Investigating obesity surgery in Tasmania

INVEST logo

Bariatric surgery, also known as obesity or weight-loss surgery, is considered an effective treatment for obesity and obesity-related illness, but it is difficult to access in Australian public hospitals.

Using focus groups and interviews with patients, interviews with health professionals, and a longer-term cohort study, the INVEST project aims:

  • to investigate the characteristics, experiences, treatment pathways and outcomes of Tasmanians who are referred to a surgeon for bariatric surgery, in both the public and private healthcare systems; and
  • to better understand the costs for patients and the health system.

The INVEST project is funded by the National Health and Medical Research Council. It is being conducted in partnership with government policy makers and clinicians to support the development of better treatment services for patients with obesity-related disease.

Can you help us with our research?

We are currently recruiting to our cohort study. This study will look at longer-term outcomes of public and private patients who have been referred to see a surgeon for bariatric surgery. Some participants will go on to have the surgery whereas others may decide not to proceed, or will be placed on a surgery wait list.

You may be able to help us with this research if:

  • You are aged 18 years or older; and
  • You have been referred to see a surgeon for bariatric surgery and have not yet had the surgery.
