Postoperative glucose control with a basal bolus versus sliding scale insulin regimen and its effect on the incidence of surgical site infections in people with type 2 diabetes mellitus a multicentre cluster randomised controlled trial.

We aim to reduce SSI in PWT2D by implementing a proactive basal-bolus insulin regimen, compared to a widely used reactive sliding scale regimen. We hypothesise that a proactive basal-bolus insulin regimen targeting a glucose level of 3.9-10 mmol/l will be superior to a reactive sliding scale regimen targeting a glucose level of 3.9-10 mmol/l, leading to a reduction of 50% of SSI’s within the first 30 days after surgery.
