Abstract

Objective: We sought to determine real-world accuracy of inpatient continuous glucose monitoring (CGM) at multiple levels of acuity in a large safety-net hospital.

Research design and methods: We analyzed records from hospitalized patients on Dexcom G6 CGM, including clinical, point of care (POC), and laboratory (Lab) glucose, and CGM data. POC/Lab values were matched to the closest timed CGM value. Encounters were divided into not critically ill (NCI) versus critically ill (CI). CGM accuracy was evaluated.

Results: Paired readings (2,744 POC-CGM; 3,705 Lab-CGM) were analyzed for 233 patients with 239 encounters (83 NCI, 156 CI). POC-CGM aggregated and average mean absolute relative differences (MARD) were 15.1% and 17.1%. Lab-CGM aggregated and average MARDs were 11.4% and 12.2%. Accuracy for POC-CGM and Lab-CGM was 96.5% and 99.1% in Clarke Error Grid zones A/B.

Conclusions: Real-world accuracy of inpatient CGM is acceptable for NCI and CI patients. Further exploration of conditions associated with lower CGM accuracy in real-world settings is warranted.

安全网医院住院患者重症和非重症护理环境中CGM的真实世界准确性。

目的：我们试图确定在一家大型安全网医院中，在多个视力水平下住院患者连续血糖监测（CGM）的真实世界准确性。研究设计和方法：我们分析了住院患者在Dexcom G6 CGM上的记录，包括临床、护理点（POC）和实验室（实验室）葡萄糖以及CGM数据。POC/Lab值与最接近的定时CGM值相匹配。接触分为非危重症（NCI）和危重症（CI）。评估CGM的准确性。结果：对233名患者239次接触（83 NCI，156 CI）的配对读数（2744 POC-CGM；3705 Lab CGM）进行了分析。在Clarke误差网格区A/B中，POC-CGM的累计和平均绝对相对差（MARD）分别为15.1%和17.1%。实验室CGM的合计和平均MARD分别为11.4%和12.2%。结论：住院患者CGM的真实世界准确性对于NCI和CI患者是可接受的。有必要在现实世界环境中进一步探索与较低CGM精度相关的条件。
