INTRODUCTION
In hospitalized patients, continuous glucose monitoring (CGM) may improve glycemic control, prevent hypoglycemic events, and reduce staff workload compared with point-of-care (POC) capillary glucose monitoring.
METHODS
To evaluate CGM accuracy and safety of use in the inpatient setting, two versions of CGM sensors were placed on 43 and 34 adult patients with diabetes admitted to non-intensive care unit (ICU) medical wards, respectively. CGM accuracy relative to POC and safety of use were measured by calculating mean absolute relative difference (MARD) and by Clarke Error Grid (CEG) analysis.
RESULTS
CGM version 2 had improved accuracy compared with CGM version 1 with MARD 17.7 compared with 21.4%. CGM accuracy did not change with POC value or with time of sensor wear. On CEG, 98.8% of paired values fell within acceptable zones A and B.
CONCLUSION
Despite reduced accuracy compared with the outpatient setting, both versions of CGMs had acceptable safety profiles in the inpatient setting.
简介
与即时检测（POC）毛细血管血糖监测相比，住院患者中连续血糖监测（CGM）可改善血糖控制、预防低血糖事件并减少医护人员的工作量。
方法
为评估 CGM 在住院环境中的准确性和使用安全性，我们分别在 43 名和 34 名患有糖尿病的成年住院患者（非 ICU 内科病房）身上放置了两种 CGM 传感器。通过计算平均绝对相对差异（MARD）和 Clarke 误差网格（CEG）分析来衡量 CGM 相对于 POC 的准确性和使用安全性。
结果
CGM 版本 2 的准确性优于 CGM 版本 1，MARD 为 17.7%，而 CGM 版本 1 的 MARD 为 21.4%。CGM 准确性不受 POC 值或传感器佩戴时间的影响。在 CEG 上，98.8%的配对值落在可接受的 A 和 B 区。
结论
尽管与门诊环境相比准确性有所降低，但两种 CGM 传感器在住院环境中均具有可接受的安全性。
