Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purposes of this study is to study if CGMs worn in the postoperative ICU or non-ICU hospital setting have adequate accuracy for blood glucose monitoring when compared to point-of-care (POC) capillary glucometers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Eligible patients will be approached by research staff either preoperatively or on the first 5 days post-surgery and offered to be enrolled. If agreed to participate, they will be fitted with a blinded CGM monitor (Dexcom G6 PRO) as soon as they are awake and alert after the surgery. They will continue to have their blood glucose check as usual in the ICU and on surgical floors with POC glucometers. On discharge, or at the end of the first CGM sensor life, the sensor will be removed and sensor data will be analyzed. CGM data will be compared with Point-of-Care blood glucose monitoring obtained in the hospital.
