The Diabetes Transition of Hospital Care (DiaTOHC) Pilot Study was a non-blinded, randomized controlled trial of a novel intervention designed to reduce readmission risk of people with diabetes.12 This study identified people with diabetes who were at high risk for readmission using the Diabetes Early Readmission Risk Indicator (DERRI®).5 The DERRI is a model that predicts 30-day readmission risk based on 10 items, including employment status, preadmission insulin use, the number of macrovascular complications, laboratory results on admission, and recent prior hospital discharge. This evidence concerns the gene INS and diabetes mellitus.
