Our team has published the first comprehensive review of risk prediction models for diabetes after bariatric surgery, "Systematic review of risk prediction models for diabetes after bariatric surgery," in one of the top surgical periodicals in the world -- British Journal of Surgery.
The purpose of this study was to identify risk prediction models of diabetes remission after bariatric surgery. Of 2330 studies retrieved, eight met the inclusion criteria. Of these, six presented development of risk prediction models and two reported validation of existing models. All included models were developed to predict diabetes remission. Internal validation using tenfold validation was reported for one model. Two models (ABCD score and DiaRem score) had external validation using independent patient cohorts with diabetes remission assessed at 12 and 14 months respectively. Of the 11 cohorts included in the eight studies, calibration was not reported in any cohort, and discrimination was reported in two. A variety of models are available for predicting risk of diabetes following bariatric surgery, but only two have undergone external validation.
