Continuous glucose monitoring during intravenous insulin infusion treatment: Assessing accuracy to enable future clinical utility.

ABSTRACT:

Aims

Continuous glucose monitoring (CGM) during intravenous insulin infusions (IVII) could reduce blood glucose (BG) testing burden in hospital, however CGM accuracy concerns exist. We aimed to assess CGM accuracy during IVII.

Methods

This multi-centre observational study included adults with type 1 diabetes (T1D) who required IVII treatment during hospital admission whilst wearing their own CGM devices (Abbott FreeStyle Libre 2, Medtronic Guardian 3, Dexcom G6). IVII dose adjustments were performed based upon standard of care BG measures. Accuracy was assessed according to mean absolute relative difference (MARD) and Consensus error grid (CEG) analysis, using time-matched (±5 minutes) pairs of CGM glucose and reference BG (point-of-care [POC], blood gas [GAS]) obtained duri
