A comprehensive search of PubMed, Ovid/MEDLINE, and CINAHL was conducted through May 20, 2025. Eligible studies included adults or children with type 1 diabetes undergoing surgery using AID systems with reported glycemic outcomes.

Sixteen studies were included: 2 observational cohorts, 9 case reports/series, 2 reviews, 1 retrospective study, 1 randomized controlled trial, and 1 expert guidance document. Across all studies, continuation of AID systems perioperatively was associated with long-duration time in range, minimal hypoglycemia, and no severe adverse events such as diabetic ketoacidosis. Technical concerns included continuous glucose monitoring signal interference from medications or surgical equipment. Expert guidance emphasized individualized planning, intraoperative monitoring, and device-specific considerations. Preliminary evidence suggests that perioperative continuation of AID systems is safe and feasible in select individuals with type 1 diabetes.
