The aim of this study is to assess whether pre-operative identification of a psychiatric diagnosis would help better define patients where further support and input may be needed to optimise their success with bariatric surgery.

The aim of this study is to assess whether pre-operative identification of a psychiatric diagnosis would help better define patients where further support and input may be needed to optimise their success with bariatric surgery. Scientific Justification The prevalence of obesity and its associated co-morbidities continues to rise worldwide, potentially impacting the economic and social welfare of individuals. Whilst bariatric surgery is the most cost-effective and efficacious treatment for obesity, weight-loss outcomes and comorbidity remissions vary significantly. A subset of patients struggle with significant psychological distress and increased care needs after bariatric surgery. It is well established that there is a significant burden of psychological and psychiatric disease amongst patients seeking bariatric surgery. However, although there is the perception that pre-existing psychiatric disorder plays a role in post-operative outcomes, this has not been borne out in studies conducted outside the UK. This study aims to examine the correlation between psychiatric disorder, collected as part of routine NHS care, with health and social care usage following bariatric surgery. Project Details This is a retrospective analysis of the Discover linked dataset will be used to address the principle research question in this study and establish whether outcomes for patients undergoing bariatric surgery can be predicted by correlating a psychiatric diagnosis to clinical outcome. Primary endpoint: • Health care usage at 1, 2 and up to 5 years after surgery including but not limited to A&E attendances, prescription of anti-depressant or other psychotropic medication, out-patient care usage, in-patient admission, admission for psychiatric care, admission for alcohol use disorder or related illness • Social care usage including but not limited to use of carers payments, • Diabetes control, as measured by HbA1c, fasting glucose, microvascular and macro vascular complications and use of hypoglycaemic medications and insulin and fasting C-peptide at 1, 2 and up to 10 years.
