The present study aimed to investigate the accuracy of the Glunovo real-time continuous glucose monitoring system (rtCGMS).
We conducted a 14-day interstitial glucose level monitoring using Glunovo rtCGMS on thirty hospitalized patients with type 2 diabetes. The flash glucose monitoring (FGM) was used as a self-control. Consistency tests, error grid analysis, and calculation of the mean absolute relative difference (MARD) were performed using R software to assess the accuracy of Glunovo rtCGMS.
Glunovo exhibited an overall MARD value of 8.89% during hospitalization, compared to 10.42% for FGM. The overall percentages of glucose values within ±10%/10, ± 15%/15, ± 20%/20, ± 30%/30, and ±40%/40 of the venous blood glucose reference value were 63.34%, 81.31%, 90.50%, 97.29%, and 99.36% for Glunovo, respectively, compared with 61.58%, 79.63%, 88.31%, 96.22% and 99.23% for FGM. The Clarke Error Grid Analysis showed that 99.61% of Glunovo glucose pairs and 100.00% of FGM glucose pairs within zones A and B.
Our study confirms the superior accuracy of Glunovo in monitoring blood glucose levels among hospitalized patients with type 2 diabetes.
本研究旨在评估 Glunovo 实时连续血糖监测系统（rtCGMS）的准确性。
我们对 30 例住院 2 型糖尿病患者使用 Glunovo rtCGMS 进行了 14 天的间质血糖水平监测，以瞬感血糖仪（FGM）作为自身对照。使用 R 软件进行一致性检验、误差网格分析和平均绝对相对差异（MARD）计算，以评估 Glunovo rtCGMS 的准确性。
住院期间，Glunovo 的总体 MARD 值为 8.89%，而 FGM 为 10.42%。Glunovo 的血糖值在静脉血糖参考值的±10%/10、±15%/15、±20%/20、±30%/30 和±40%/40 范围内的百分比分别为 63.34%、81.31%、90.50%、97.29%和 99.36%，而 FGM 的相应百分比分别为 61.58%、79.63%、88.31%、96.22%和 99.23%。Clarke 误差网格分析显示，Glunovo 的 99.61%血糖对和 100.00%的 FGM 血糖对位于 A 区和 B 区。
本研究证实了 Glunovo 在监测 2 型糖尿病住院患者血糖方面的准确性更优。
