Barriers for bariatric surgery in provincial New Zealand: a qualitative analysis.

Background: Bariatric surgery is the most effective treatment for people with obesity. It has been shown that there's is a complex psychosocial overlay in the pathophysiology and treatment, which requires specific consideration when delivering care. There is a significant drop out rate for patients accepted on to bariatric programmes in New Zealand, resulting in failure to progress to surgical intervention.

Methods: We conducted individual, semi-structured interviews with patients who were accepted onto the bariatric surgery programme but did not complete the programme, or receive an operation between 2015 and 2020. Grounded theory methodology was used to create an exploratory framework to identify and describe the themes encountered. An iterative process of thematic analysis and comparison between participants experiences was used to consolidate the shared key barriers. This study aims to explore patients experiences of a bariatric surgery programme to understand barriers and enablers to complete a bariatric programme and receive an operation. Adding to previous qualitative work investigating patients experience of bariatric surgery programmes in New Zealand.

Results: Five themes of barriers that patients face to receiving bariatric surgery were identified. These were preoperative weight loss requirement, experiencing the social stigma of obesity, communication, socioeconomic and geographic barriers, and community support. These five themes often co-exist in patients experiences and combine, to cause patients to disengage with the bariatric service.

Conclusion: Many factors contribute to eligible patients not receiving bariatric surgery once accepted onto the programme. Specified weight loss goals was the most significant barrier. Community support and online resources were significant enablers. This study should inform changes to bariatric programmes in New Zealand.
