Prevalence of mental disorders in patients with pathological obesity selected for bariatric surgery in the KOS-BAR nationwide multi-centre pilot programme - a preliminary report.

Abstract

Obesity affects over 600,000 people in Poland, and bariatric surgery is a vital part of the multidisciplinary approach to treatment. To improve outcomes, Poland’s public health institutions implemented the KOS-BAR programme, a multicentre nationwide pilot initiative that includes psychiatric evaluations of patients. The aim of this study was to assess the prevalence of mental disorders, verify diagnoses, and evaluate pharmacotherapy efficacy for patients under psychiatric treatment and selected for bariatric surgery. Of the 180 patients evaluated, 40% had a history of mental disorders, with depressive and eating disorders being the most common diagnoses. Patients selected for revision surgery had a higher incidence of depressive and compulsive eating disorders. Psychiatric support can improve patient cooperation and optimize long-term outcomes after bariatric surgery. A more complete evaluation of the psychological profile and depressive disorder’s impact on bariatric treatment outcomes will be the next step for this group of patients.

No association between history of psychiatric treatment and postoperative weight reduction after bariatric surgery

“…Other studies indicated up to 5 times higher frequency of preoperative psychiatric treatment [ 4 , 25 , 30 ]. Also, Polish preliminary data on the prevalence of mental disorders in patients qualified for the nationwide multi-center pilot of bariatric obesity treatment program (KOS-BAR) showed that 12.1% patients were in psychiatric treatment but there were additional 11.7% with de novo diagnosis [ 31 ].…”
