In 2023, we employed Dexcom G6 for real-time continuous glucose monitoring (rt-CGM); it showed high usefulness but unsatisfactory accuracy in type 1 diabetes summer camp (camp) participants.
To assess the usefulness, recommendation and accuracy of a new rt-CGM system in camp, 2024.
Sensor glucose (SG) concentrations were measured by Dexcom G7 (G7) from 6 days prior to camp. Usefulness and recommendation were assessed by questionnaire. Twenty-one children with type 1 diabetes and 52 healthcare providers (HCPs) participated. CGM-associated metrics were measured 6 days prior to (off camp: 6 days) and during camp (on camp: 2 days).
G7 was rated highly for its sensor insertion, visualization of SG variation and convenience during camp. The SG value accuracy scored relatively low. G7's usefulness and recommendation among campers were significantly higher than those of G6, utilized the previous year, and they were both almost equally highly rated by HCPs. The mean absolute relative difference (MARD) was 11.3% (G6: 16.0%) on camp and 11.0% (G6: 19.7%) off camp. The coefficient of variation was 34.4% (G6: 60.3%) on camp and 35.9% (G6: 63.1%) off camp, while the glucose management indicator was 7.44% for G7 (G6: 8.04%). The glycemic management metrics on camp were better than those off camp. Graphical analyses also showed sufficient accuracy.
G7 was rated higher in usefulness and recommendation than G6 among participants. G7 also exhibited improved accuracy and was considered a useful rt-CGM tool in a camp setting. Glucose management on camp was significantly improved because of the HCPs' multi-directional efforts.
2023年，我们使用德康G6进行实时连续血糖监测（rt-CGM）；在1型糖尿病夏令营参与者中，它显示出很高的实用性，但准确性不尽人意。
评估2024年一种新型rt-CGM系统在夏令营中的实用性、推荐度和准确性。
在夏令营开始前6天，使用德康G7（G7）测量传感器葡萄糖（SG）浓度。通过问卷调查评估实用性和推荐度。21名1型糖尿病儿童和52名医疗保健提供者（HCP）参与。在夏令营开始前6天（离营：6天）和夏令营期间（在营：2天）测量与CGM相关的指标。
G7在传感器插入、SG变化可视化以及夏令营期间的便利性方面获得了高度评价。SG值准确性得分相对较低。G7在营员中的实用性和推荐度显著高于前一年使用的G6，并且HCP对它们的评价几乎同样高。在营期间平均绝对相对差异（MARD）为11.3%（G6：16.0%），离营期间为11.0%（G6：19.7%）。在营期间变异系数为34.4%（G6：60.3%），离营期间为35.9%（G6：63.1%），而G7的血糖管理指标为7.44%（G6：8.04%）。在营期间的血糖管理指标优于离营期间。图形分析也显示出足够的准确性。
在参与者中，G7在实用性和推荐度方面的评分高于G6。G7的准确性也有所提高，被认为是夏令营环境中一种有用的rt-CGM工具。由于HCP的多方面努力，夏令营期间的血糖管理得到了显著改善。
