Study on clinical utility of continuous glucose monitoring system / 中国实用内科杂志

ABSTRACT

Objective To determine the accuracy and reliability of continuous glucose monitoring system(CGMS)in intensive monitoring blood glucose level.Methods The analysis was conducted on 48 type 2 diabetes patients to compare the glucose levels of glucose meter and CGMS.Each patients received CGMS for 3 days during his/her hospitalization.The data were analyzed according to correlation coefficient analysis,mean absolute error,sensitivity and specificity.Results The mean duration of CGMS recording was(71.4?0.6)h.From the data that paired glucose readings and CGMS,the coefficients of correlation ranged from 0.79 to 0.90 and the mean absolute error ranged from 6.7% to 10.0%.The sensitivity and specificity to detect hyperglycemia were 93.15% and 95.95%,respectively.Conclusion There is a good correlation between sensor readings of interstitial fluid glucose level and capillary blood glucose readings.The results indicate that CGMS is of clinical utility as a holter-type glucose tracking device.
