About

This trial investigates the effects of continuous glucose monitoring (CGM) and an in-hospital diabetes team on in-hospital glycemic and clinical outcomes in patients with type 2 diabetes compared to standard glucose point-of-care (POC) testing and an in-hospital diabetes team.

Full description

In Denmark and worldwide, 15-20 % of hospitalised patients have diabetes mellitus. For most patients, diabetes is not the primary cause of admission. The patients are therefore under the care of non-diabetes specialists. Consequently, diabetes management can be inadequate resulting in hypoglycemia, hyperglycemia, and increased glycemic variability, which might increase patient mortality, morbidity, and length of hospital stay. Despite these challenges, a recent review concludes that in-hospital diabetes management is under-researched. Therefore, new in-hospital diabetes management strategies are greatly needed.

Continuous glucose monitoring (CGM) might accommodate this need by providing 288 glucose readings per day compared to usual glucose point-of-care (POC) testing from finger-prick blood 3-5 times per day during admission. CGM glucose levels can be transmitted from the patient's room to a monitoring screen at the nursing stations. This setup is called telemetric CGM. Outstanding results on glycemic and clinical outcomes in an out-hospital setting exist, however, In-hospital CGM has been associated only with a clinically insignificant reduction of mean daily glucose levels and a small increased detection rate of hypoglycemia of glucose levels <3 mmol/L (<54 mg/dL) compared to POC. Reasons for this might be that an in-hospital diabetes team (i.e., educated diabetes nurses with CGM competencies) is imperative in achieving optimal use of telemetric CGM.

This trial investigates if telemetric CGM and an in-hospital diabetes team improve patients' in-hospital glycemic and clinical outcomes compared to POC glucose testing and an in-hospital diabetes team

---

166 participants in 2 patient groups

POC-arm

Active Comparator group

Description:

Subjects are monitored by point-of-care (POC) glucose testing. Diabetes management is done by usual ward nurses and guided by an in-hospital diabetes team. A blinded CGM is mounted in the POC-arm for outcome analysis.

Treatment:

Device: FreeStyle Precision Pro Glucometer for glucose POC testing

CGM-arm

Experimental group

Description:

CGM-arm subjects are monitored by CGM viewed by the in-hospital diabetes team in addition to POC glucose testing performed by usual ward nurses. Diabetes management is done by usual ward nurses by POC glucose testing and guided by an in-hospital diabetes team with acces to CGM data.

Treatment:

Device: Dexcom G6 Continuous Glucose Monitoring System (Dexcom Inc., San Diego, USA)
