The using status quo and analysis of POCT glucose meter

Abstract

Objective To investigate the problems during using, standard and quality management of the POCT glucose meters in hospital, to analyze the solutions, and to provide reference data for improving the test level of POCT in hospital. Methods The amount, brand and application of portable glucose meters in the hospital were obtained by 3 rounds of surveillance from May to July in 2013. All of those glucose meters were taken part in external quality assessment of Clinical Laboratory Center of National Health and Family Planning Commission. The test results of those glucose meters were compared with that of automatic biochemical analyzer, the comparison results were then analyzed. Results The POCT glucose meters possessed 5 brands in our hospital, and the amount and type of glucose meters in some clinical departments were often changed. When 4 brands which were detected as quality control samples by ministry of health, the accuracy of detection results of 3 concentration of brand Ⅲ were substandard, the CV% of two levels were 11.9% and 10.1% respectively, the remaining 3 brands were in line with the requirements. The qualified percentages of 3 times of comparison were 85.0%, 92.0% and 97.4%. Conclusions The hospital should select the brand of portable glucose meters reasonably, correct use of glucose meters, and it is very necessary to build indoor and interstitial quality evaluation system, at the same time, suggesting the hospital to establish the POCT quality management team, to carry out the instrument comparison periodically, so to guarantee the accurate, reliable results of POCT in hospital.(Chin J Lab Med, 2016, 39: 643-645) Key words: Glucose tolerance test; Monitoring, ambulatory; Point-of-care systems; Quality assurance, health care
