The Role of Calibration Practices in Optimizing Continuous Glucose Monitor Accuracy in Critically Ill Patients.

ABSTRACT:

Background

In the ICU, continuous glucose monitors (CGMs) may improve glycemia and reduce the need for point-of-care blood glucose (POC BG) monitoring, but face challenges because of clinical conditions that affect accuracy.

Research question

What is the feasibility of using POC BG calibration to improve CGM accuracy?

Study design and methods

This feasibility study pooled data from a retrospective study of patients with COVID-19 in the ICU and a prospective single-arm clinical trial of patients in the ICU. Our sample included 110 patients receiving IV insulin monitored using a hybrid CGM plus POC BG protocol with a factory-calibrated Dexcom G6 CGM (Dexcom, Inc.). Validation was required for initial and ongoing nonadjunctive use or for standalone use and was defined as
