Comparing continuous glucose monitoring to fingerstick blood sugar checks

Continuous GLUCOse Monitoring System With a SENSor Compared to Fingerstick Glucose Monitoring in Surgical Wards (GLUCOSENS)

Not applicable Interventional Odense University Hospital · NCT06473480

This study tests if a continuous glucose monitoring system can help adult surgical patients manage their blood sugar better than traditional fingerstick tests.

What this trial studies

This clinical trial compares the effectiveness of a continuous glucose monitoring system (CGMS) with traditional fingerstick blood glucose monitoring in adult surgical patients. The study aims to determine if CGMS can provide better glucose management, reduce complications, and enhance patient and nursing staff experiences. Participants will have their glucose levels monitored continuously via a subcutaneous sensor, while the accuracy of CGMS readings will be compared to those obtained from fingerstick tests. The trial also seeks to evaluate the impact on nursing workload and patient satisfaction.

Who should consider this trial

Good fit: Ideal candidates include hospitalized adults in surgical wards at risk of hypo- and hyperglycemia who can communicate in Danish.

Not a fit: Patients who are cognitively impaired or those whose glucose monitoring is solely due to parenteral nutrition treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved blood sugar control and enhanced experiences for both patients and nursing staff in surgical settings.

How similar studies have performed: Previous studies have shown that continuous glucose monitoring systems are accurate and effective compared to fingerstick monitoring, indicating a promising approach.
