AIMS/INTRODUCTION: This study evaluated the usability, satisfaction, and accuracy of a real-time continuous glucose monitoring (rt-CGM) in children and adolescents with type 1 diabetes (T1D) attending a summer camp.
Seven children and adolescents with T1D (camper) and 31 of healthcare providers (HCPs) participating in a 2-day summer camp in Kumamoto, Japan were enrolled. The usability and satisfaction were evaluated by tailored questionnaire. The accuracy of rt-CGM was evaluated using self-monitoring of blood glucose (BG) and sensor glucose (SG) values before or after (off camp) and during (on camp) the camp.
The score of the usefulness of rt-CGM showed 3.29 ± 0.90 in campers and 4.23 ± 0.87 in HCPs (P = 0.017). The degree of recommendation score for rt-CGM was 3.29 ± 1.11 in campers and 4.23 ± 0.79 in HCPs (P = 0.013). Time in range (TIR) off camp was 45.9% and that on camp was 57.0%. Time above range (TAR) off camp was 53.4% and that on camp was 42.4%. The mean absolute relative difference (MARD) off camp was 19.7% ± 25.2%, whereas that on camp was 16.0% ± 14.8% (P = 0.367). Clinically acceptable zones of the error grid analyses were approximately 96% in total.
Rt-CGM exhibited higher usability and recommendation scores in HCPs than those in campers. This may be related to relatively lower accuracy in rt-CGM. Overall usability and recommendation are clinically satisfactory, but due to relatively low accuracy, no decision should be made based on a single, non-verified SG value alone.
目的/引言：本研究评估了参加夏令营的1型糖尿病（T1D）儿童和青少年使用实时连续血糖监测（rt-CGM）的易用性、满意度和准确性。
招募了7名患有T1D的儿童和青少年（营员）以及31名医疗保健提供者（HCPs），他们参加了在日本熊本举行的为期2天的夏令营。通过定制问卷评估易用性和满意度。使用夏令营前或后（离营时）以及夏令营期间（在营时）的自我血糖监测（BG）和传感器血糖（SG）值评估rt-CGM的准确性。
rt-CGM的有用性评分在营员中为3.29±0.90，在HCPs中为4.23±0.87（P = 0.017）。rt-CGM的推荐评分程度在营员中为3.29±1.11，在HCPs中为4.23±0.79（P = 0.013）。离营时血糖在目标范围内（TIR）的时间为45.9%，在营时为57.0%。离营时血糖高于目标范围（TAR）的时间为53.4%，在营时为42.4%。离营时的平均绝对相对差异（MARD）为19.7%±25.2%，而在营时为16.0%±14.8%（P = 0.367）。错误网格分析的临床可接受区域总计约为96%。
与营员相比，rt-CGM在HCPs中表现出更高的易用性和推荐评分。这可能与rt-CGM相对较低的准确性有关。总体易用性和推荐在临床上是令人满意的，但由于准确性相对较低，不应仅基于单个未经核实的SG值做出决策。
