We have instituted hospital-wide proficiency testing of nursing personnel who operate glucose-monitoring instruments. Whole blood samples with known glucose levels were distributed to all nursing units for analysis on a biweekly basis. Measurements obtained by nurses on glucose meters were compared with one another and with true glucose levels to identify discrepant performance and institute corrective action. After 10 months of operation, we found that the nursing units using glucose meters daily showed mean absolute variation from true glucose of 12.7% (range, 10.0% to 17.7%), whereas intermittent users showed mean absolute variation of 15.3% (range, 10.7% to 24.0%). Of 552 total paired determinations, 199 (36.9%) differed from true glucose by greater than 15%. This program was successful in establishing uniform quality control procedures among nonlaboratory personnel who had no previous experience in laboratory measurements.
我们已对操作血糖监测仪器的护理人员开展全院范围的能力测试。将已知血糖水平的全血样本每两周分发给所有护理单元进行分析。护士们用血糖仪测得的结果相互比较，并与真实血糖水平比较，以识别差异表现并采取纠正措施。运行10个月后，我们发现，每日使用血糖仪的护理单元与真实血糖的平均绝对偏差为12.7%（范围为10.0%至17.7%），而间歇性使用者的平均绝对偏差为15.3%（范围为10.7%至24.0%）。在总共552次配对测定中，199次（36.9%）与真实血糖的差异大于15%。该项目成功地在以前没有实验室测量经验的非实验室人员中建立了统一的质量控制程序。
