摘要
目的寻求一种可以检出血浆凝血酶原时间实验分析前因素影响的质控方法。方法对532例肝病患者同一时间检测的PT和白蛋白结果进行分析。结果通过患者数据质控法,对532例肝病患者的PT结果进行回顾性分析,检出室内质控未检出但可能存在误差的数据22例,其中16例是由于采血或混匀不当、送检不及时、血量不够等造成的结果延长;2例是由于口服华发林造成的结果延长;4例和原结果基本一致,误差检出概率82%;未能检出的失控数据19例,假失控概率3.6%。结论患者数据质控法适用于PT质控,值得推广应用。但由于其受多种因素的限制和影响,目前还不能作为一种主要的质控方法,只能作为常规质控方法的补充。
Objective To discuss a quality control method to avoid being influenced by the factors before operation. Methods PT and ALB in 532 cases with hepatic disease were detected and analyzed. Results 22 cases of possible errors were detected by patient＇s data quality control and were not found out by internal quality control. 16 cases were prolonged by some nursing problems in collecting blood samples such as incorrect collections,different collection areas,not enough quantity, not sending for checking in time; 2 cases took warfarin;4 cases were consistent with the original results. The probability of the misnomer checked out and the rate of false control was 82.0% and 3.6%. Conclusion Quality control of patient＇s data is suitable for the quality control of PT,and it is worth popularizing and applying chnically. But as a master control rule,it is unsuitable,only can be as a supplement of routine quality control.
