Transition of Single Surgeon Bariatric Service to an Interdisciplinary Multiple Surgeon Model

This retrospective study will analyse the transition of an Australian hospital which significantly increased volume of bariatric operations after introduction of a clinical pathway, and to assess the outcomes. Barriers to introduction of the multidisciplinary pathway and the means to overcome these will also be analysed and discussed. The analysis will also determine if there are any other areas of bariatric surgery which can be further investigated to optimise current practice.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Post-operative length of stay (nights)	This will be measured in number of nights the participant stayed in hospital after the procedure.	The number of nights the participant stay in hospital from the day of procedure to the day of hospital discharge. This time period occurs immediately after the procedure. This data will be retrospectively reviewed on an average of 5 years.
End weight loss	Post-operative weight loss	Up to 12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
End weight loss	Post-operative weight loss	Up to 24 months
End weight loss	Post-operative weight loss	Up to 36 months
Intraoperative time	Duration of operative time measured in minutes	The start time of the operation to the end time of the procedure. This data will be retrospectively reviewed on an average of 5 years.
Post-operative complications	Complications which occurred in the post operative period	Up to 36 months
Number of operations performed in time period	The number of operations which occurred in each group	Retrospectively reviewed, 1 yearly
Type of Operation Performed	The number of the different types of bariatric operations which occurred in each group	Retrospectively reviewed, 1 yearly
