Summary

A multicentre, matched-pair, cluster randomised controlled superiority trial to investigate the effect of a proactive basal bolus insulin regimen compared to the reactive sliding scale insulin regimen, targeting a glucose level of 3.9-10.0 mmol/L, to reduce the number of surgical site infections within the first 30 days postoperatively in adult patients with diabetes mellitus type 2.

Detailed description

People with type 2 diabetes mellitus (PWT2D) are at increased risk of postoperative complications, especially surgical site infections (SSI). The aim of this study to reduce SSI in PWT2D by implementing a proactive basal-bolus insulin regimen, compared to the reactive sliding scale regimen. Adult patients with type 2 diabetes will be included in this multi-centre study. Participants will receive a blind CGM, i.e. glucose data are masked for the participants and study team, from admission to the ward until discharge from the hospital. In addition, all participants are asked to complete several questionnaires 30 days after surgery. Both regimens are currently used in clinical practice. Therefore, there is no additional trial-related burden depending on the intervention group allocation. Participants will be monitored intensively and insulin dosage will be adjusted adequately to the measured glucose values by the treatment team. The sample size is based on the SSI incidence rates. Wards are matched into pairs with comparable baseline incidence rates and in each pair, one ward will be randomly assigned to the intervention group; the other serves as the control. 18 wards from 8 participating centres are planned to be recruited, this translates to 9x2x56=1008 evaluable participants.
