Continuous glucose monitoring (CGM) improves diabetes management, but its reliability in individuals on hemodialysis is poorly understood and potentially affected by interstitial and intravascular volume variations.
We assessed the accuracy of a factory-calibrated CGM by using venous blood glucose measurements (vBGM) during hemodialysis sessions and self-monitoring blood glucose (SMBG) at home.
Twenty participants completed the protocol. The mean absolute relative difference of the CGM was 13.8% and 14.4%, when calculated on SMBG (n = 684) and on vBGM (n = 624), and 98.7% and 100% of values in the Parkes error grid A/B zones, respectively. Throughout 181 days of CGM monitoring, the median time in range (70-180 mg/dL) was 38.5% (interquartile range 29.3-57.9), with 28.7% (7.8-40.6) of the time >250 mg/dL.
The overall performance of a factory-calibrated CGM appears reasonably accurate and clinically relevant for use in practice by individuals on hemodialysis and health professionals to improve diabetes management.
连续血糖监测(CGM)可改善糖尿病管理,但在血液透析患者中的可靠性尚不清楚,且可能受到间质和血管内容量变化的影响。
我们评估了在血液透析期间使用静脉血糖测量值(vBGM)和在家中自我监测血糖值(SMBG)对工厂校准的 CGM 的准确性。
20 名参与者完成了方案。当基于 SMBG(n = 684)和 vBGM(n = 624)计算时,CGM 的平均绝对相对差异分别为 13.8%和 14.4%,并且分别有 98.7%和 100%的数值位于 Parkes 误差网格 A/B 区。在 181 天的 CGM 监测期间,范围内(70-180mg/dL)的中位数时间为 38.5%(四分位距 29.3-57.9),>250mg/dL 的时间占 28.7%(7.8-40.6)。
工厂校准的 CGM 的整体性能似乎具有相当的准确性和临床相关性,可用于血液透析患者和卫生专业人员改善糖尿病管理。
