McGlone ER, Carey I, Veličković V, et al. - Researchers used data from a national database to investigate the effect of bariatric surgery on type 2 diabetes mellitus (T2DM) resolution in patients with obesity and T2DM needing insulin (T2DM-Ins). They also intended to construct a health economic model to assess the cost-effectiveness of surgery in this cohort vs best medical treatment. They studied outcomes of patients with obesity and T2DM-Ins who received primary bariatric surgery between 2009 and 2017. As per findings, bariatric surgery in patients with obesity and T2DM-Ins was found to be related to high rates of postoperative cessation of insulin treatment, which is, in turn, a major driver of overall decreases in direct healthcare expense. These data indicate that a cost saving strategy for the national healthcare provider (National Health Service) over a 5-year time horizon is the one that utilises bariatric surgery for patients with obesity and T2DM-Ins.
