Abstract

Background: Two weeks of continuous glucose monitoring (CGM) sampling with >70% CGM use is recommended to accurately reflect 90 days of glycemic metrics. However, minimum sampling duration for CGM use <70% is not well studied. We investigated the minimum duration of CGM sampling required for each CGM metric to achieve representative glycemic outcomes for <70% CGM use over 90 days.

Methods: Ninety days of CGM data were collected in 336 real-life CGM users with type 1 diabetes. CGM data were grouped in 5% increments of CGM use (45%-95%) over 90 days. For each CGM metric and each CGM use category, the correlation between the summary statistic calculated using each sampling period and all 90 days of data was determined using the squared value of the Spearmen correlation coefficient (R2).

Results: For CGM use 45% to 95% over 90 days, minimum sampling period is 14 days for mean glucose, time in range (70-180 mg/dL), time >180 mg/dL, and time >250 mg/dL; 28 days for coefficient of variation, and 35 days for time <54 mg/dL. For time <70 mg/dL, 28 days is sufficient between 45 and 80% CGM use, while 21 days is required >80% CGM use.

Conclusion: We defined minimum sampling durations for all CGM metrics in suboptimal CGM use. CGM sampling of at least 14 days is required for >45% CGM use over 90 days to sufficiently reflect most of the CGM metrics. Assessment of hypoglycemia and coefficient of variation require a longer sampling period regardless of CGM use duration.

连续血糖监测指标的最小采样持续时间,以在次优连续血糖监测仪使用中实现代表性血糖结果。
背景:建议进行两周的连续血糖监测(CGM)采样,使用>70%的CGM,以准确反映90天的血糖指标。然而,CGM使用的最短采样时间方法:在336名患有1型糖尿病的真实CGM用户中收集了90天的CGM数据。CGM数据在90天内以5%的CGM使用增量(45%-95%)进行分组。对于每个CGM指标和每个CGM使用类别,使用Spearmen相关系数(R2)的平方值来确定使用每个采样期计算的汇总统计数据与所有90天数据之间的相关性。结果:对于CGM在90天内使用45%至95%,平均葡萄糖的最短采样期为14天,时间在范围内(70-180 mg/dL),时间>180 mg/dL,时间>250mg/dL;变异系数为28天,使用80%CGM的时间为35天。结论:在次优CGM使用中,我们为所有CGM指标定义了最小采样持续时间。对于90天内超过45%的CGM使用,需要至少14天的CGM采样,以充分反映大多数CGM指标。无论CGM的使用持续时间如何,低血糖和变异系数的评估都需要更长的采样期。

期刊介绍: The Journal of Diabetes Science and Technology (JDST) is a bi-monthly, peer-reviewed scientific journal published by the Diabetes Technology Society. JDST covers scientific and clinical aspects of diabetes technology including glucose monitoring, insulin and metabolic peptide delivery, the artificial pancreas, digital health, precision medicine, social media, cybersecurity, software for modeling, physiologic monitoring, technology for managing obesity, and diagnostic tests of glycation. The journal also covers the development and use of mobile applications and wireless communication, as well as bioengineered tools such as MEMS, new biomaterials, and nanotechnology to develop new sensors. Articles in JDST cover both basic research and clinical applications of technologies being developed to help people with diabetes.
