皮下连续血糖监测（CGM）可能有助于危重患者实现血糖控制。本研究旨在评估FreeStyle Navigator I在危重患者中的准确性和可靠性，并评估影响准确性和可靠性的患者相关因素。本研究是一项回顾性分析，数据来自一项在20张床位的混合重症监护病房进行的随机对照试验。以动脉血糖样本作为参考，评估分析准确度、临床准确度和可靠性。根据最近的共识建议，使用中位绝对相对差（中位ARD）、Bland-Altman图、ISO系统准确度标准（ISO 15197：2013）和Clarke误差网格分析（CEG）进行评估。我们分析了155例危重患者的2840个配对测量值。所有配对值的中位ARD为13.3 [6.9-22.1]%。中位ARD在低血糖和高血糖范围内均显著较高（分别为32.4 [12.1-53.4] %和18.7 [10.7-28.3] %，p
Subcutaneous continuous glucose monitoring (CGM) may have benefits in achieving glycemic control in critically ill patients. The aim of this study was to assess the accuracy and reliability of the FreeStyle Navigator I in critically ill patients and to assess patient related factors influencing the accuracy and reliability. This study is a retrospective analysis of data from a randomized controlled trial conducted in a 20-bed mixed intensive care unit. Analytical accuracy, clinical accuracy and reliability were assessed against arterial blood glucose samples as reference. Assessment was according to recent consensus recommendations with median absolute relative difference (median ARD), Bland-Altman plots, the ISO system accuracy standards (ISO 15197:2013) and Clarke error grid analysis (CEG). We analyzed 2840 paired measurements from 155 critically ill patients. The median ARD of all paired values was 13.3 [6.9-22.1]%. The median ARD was significantly higher in both the hypoglycemic and the hyperglycemic range (32.4 [12.1-53.4] % and 18.7 [10.7-28.3] % respectively, p
