What this trial studies

This multi-center, pragmatic, randomized controlled trial aims to evaluate the effectiveness of continuous glucose monitoring (CGM) compared to conventional glucose monitoring in enhancing surgical outcomes for patients with diabetes or impaired glucose tolerance. The study will assess the impact of CGM on the comprehensive complication index (CCI) within 30 days post-surgery, considering factors such as age, type of surgery, and preoperative glycemic levels. Participants will use CGM for at least 6 hours before surgery and continue monitoring until 7 days post-surgery or discharge, allowing for real-time glucose management during the perioperative period.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years with diabetes mellitus or impaired glucose tolerance scheduled for major thoracic, abdominal, orthopedic, or neurosurgery.

Not a fit: Patients who are not diabetic or do not have impaired glucose tolerance, or those with certain comorbidities affecting surgical outcomes, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative complications and improve recovery for diabetic patients undergoing major surgeries.

How similar studies have performed: Previous smaller studies have shown promising results for CGM in intraoperative glycemic management, but this study aims to provide larger-scale real-world evidence.
