Bariatric surgeons' views on pre-operative factors associated with improved health-related quality of life following surgery

Bariatric surgery is an effective treatment for severe obesity, affording significant improvements in weight loss and health-related quality of life. However, bariatric surgeons' views on whether certain pre-operative factors predict improvements in post-operative health-related quality of life, and if so, which ones, are largely unknown. This cross-sectional survey study examined the views of 58 bariatric surgeons from Australia and New Zealand. A total of 18 factors were selected for exploration based on their mention in the literature. Participants rated the extent to which they thought these pre-operative factors would improve post-operative health-related quality of life. Responses showed that bariatric surgeons held diverse perspectives and revealed a lack of consensus regarding "predictive" factors. Generally, respondents agreed that better than average health literacy, higher socioeconomic status, good physical and psychological health, and positive social support were predictors of improved health-related quality of life following surgery. However, poor eating behaviours, smoking, and the use of alcohol or other substances were deemed negative predictors. Interestingly, aside from higher socioeconomic status, good psychological health, and positive social support, none of the aforementioned views aligned with existing literature. This study offers an initial insight into bariatric surgeons' views on the influence of different pre-operative factors on post-operative health-related quality of life. The array of views identified suggests that there may be an opportunity for medical education, but the findings warrant caution due to the sample size. Replication with a larger survey may be useful, especially as predicted health-related quality of life outcomes could guide decisions regarding surgical (non)progression.
