Evaluating perioperative glycemic control of non-cardiac surgical patients with diabetes

Abstract

Introduction Hyperglycemia during the perioperative period has generally been accepted as a contributor of poor outcomes in patients with diabetes mellitus undergoing surgery. Although an optimal glycemic range has not been clearly established in the literature, a consensus among national medical organizations generally recommends serum glucose levels to be maintained less than 180 mg/dL during the perioperative period. Materials and methods The primary purpose of this evidence-based project was to identify the range of blood glucose values obtained from adult patients with diabetes mellitus undergoing non-cardiac surgery at a large military medical facility. The secondary purpose of this project was to assess the need for change in future practice. A retrospective review of the electronic medical record was conducted to identify adult surgical patients with diabetes scheduled for non-cardiac surgery. Preoperative and postoperative blood glucose values were obtained from the electronic medical record. The frequency of blood glucose values maintained within the recommended range of 140-180 mg/dL was recorded. Additional demographic data were collected to include age, height, weight, body mass index, length of surgery, and insulin/oral glycemic medications. Results Of the 9,449 surgeries performed between January 1, 2013, and December 31, 2013, there were 762 (8%) adult non-cardiac surgical patients identified with either a diagnosis of diabetes or a blood glucose value reporte…
