What this trial studies

This multicentre trial investigates the effectiveness of a proactive basal bolus insulin regimen versus a reactive sliding scale insulin regimen in reducing surgical site infections (SSI) in adult patients with type 2 diabetes undergoing gastrointestinal or vascular surgery. Participants will be monitored with a blind continuous glucose monitor (CGM) from admission until discharge, and insulin dosages will be adjusted based on glucose levels. The study aims to enroll 1008 participants across 18 wards in 8 centers, with wards matched by baseline SSI rates to ensure robust comparisons. Participants will also complete questionnaires 30 days post-surgery to assess outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 or older with type 2 diabetes mellitus who are scheduled for gastrointestinal or vascular surgery.

Not a fit: Patients with type 1 diabetes, those undergoing specific surgeries like complete pancreatectomy or bariatric surgery, and individuals using continuous insulin pumps may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of surgical site infections in patients with type 2 diabetes, improving postoperative recovery and outcomes.

How similar studies have performed: Previous studies have shown that proactive insulin management can reduce postoperative complications, suggesting potential success for this approach.
