The flash glucose monitoring system FreeStyle Libre (Abbott Diabetes Care Ltd., Witney, UK) measures interstitial glucose concentrations and continuously stores measurement values every 15 minutes. To obtain a current glucose reading, users have to scan the sensor with the reader. In a clinical trial, 5% of the scanned data showed relative differences of more than ±10% compared with continuously stored data points (median -0.5%). Such differences might impact results of studies using this system. It should be indicated whether scanned or continuously stored data were used for analyses. Health care professionals might have to differentiate between data reports from clinical software and the scanned data their patients are provided with. Additional information on these differences and their potential impact on therapeutic decisions would be helpful.
免校准葡萄糖监测系统FreeStyle Libre(英国威特尼雅培糖尿病护理有限公司)可测量组织间液葡萄糖浓度,并每15分钟持续存储测量值。为获取当前血糖读数,用户必须使用读取器扫描传感器。在一项临床试验中,5%的扫描数据与持续存储的数据点相比显示出超过±10%的相对差异(中位数为-0.5%)。此类差异可能会影响使用该系统的研究结果。应指明分析使用的是扫描数据还是持续存储的数据。医疗保健专业人员可能需要区分临床软件生成的数据报告和提供给患者的扫描数据。关于这些差异及其对治疗决策潜在影响的更多信息将很有帮助。
