目的了解广东省疾病预防控制(简称“疾控”)机构实验室人员对外部质控的认知现状及对外部质控工作的需求,为开展全省实验室质控工作提供相关信息和技术依据。方法向全省120家各级疾控机构实验室发放问卷进行调查,调查内容包括:广东省疾控机构实验室对外部质控的认知现状、需求、工作情况及对外部质控组织机构的能力要求等。结果共向全省120家各级疾控机构实验室发放了调查表,有112家实验室填写完整并寄回调查表。112家被调查实验室对外部质控相关知识的回答正确率为85.71%～92.86%。98.21%(110/112)的实验室接受的外部质控信息主要来自上级部门的通知;91.07%(102/112)的实验室有参加外质控工作的程序;56.25%(63/112)的实验室否认参与外质控项目与工作业绩挂钩;93.69%(104/111)的实验室在出现不满意结果时会进行内部整改;在获得满意结果时,只有8.04%(9/112)的实验室会奖励检测人员;66.07%(74/112)的实验室认为我国现有的外部质控项目太少。实验室外质控中出现不满意结果的原因主要集中在实验室人员操作及仪器试剂方面,其中69.64%(78/112)的实验室认为是实验室人员操作问题,70.54%(79/112)的实验室认为是仪器试剂问题。结论广东省疾控机构近10年的实验室质量控制工作效果明显,应针对不同级别和不同地区的实验室,分类分级制定外质控计划和活动,使外质控活动更适合于不同类别实验室。
Objective To understand the status quo of external quality control and the need of external quality control in the laboratory of Guangdong Provincial Disease Prevention and Control (abbreviated “CDC”) institutions and to provide relevant information for the laboratory quality control work in the province and Technical basis. Methods A questionnaire was sent to 120 CDC laboratories throughout the province. The survey includes: the status quo, requirements and work conditions of CDC laboratories in external control of Guangdong Province; Ability requirements and so on. Results A total of 120 questionnaires were distributed to CDC laboratories at all levels in the province, with 112 laboratories completing the questionnaire and sending back the questionnaires. The correct response rate of the 112 surveyed laboratories to external quality-related knowledge was 85.71% ~ 92.86%. 98.21% (110/112) of the laboratories accepted the external quality control information mainly from the notification of the superior department; 91.07% (102/112) of the laboratories had the procedures of participating in the external quality control work; 56.25% (63/112) The laboratory denied that the external quality control projects were linked to the performance of the work. 93.69% (104/111) of the laboratories conducted internal rectification when dissatisfied results were obtained. Only 8.04% (9/112) of the experiments were conducted when satisfactory results were obtained 667% (74/112) laboratories think there are too few external quality control projects in our country. Among the reasons for unsatisfactory results in laboratory quality control, 69.64% (78/112) of the laboratories considered laboratory personnel operation problems, 70.54% (79/112) The lab considers it a problem with instrument reagents. Conclusion The quality control work of laboratory in Guangdong Province CDC in recent 10 years is obvious. External quality control plans and activities should be formulated according to different levels and different laboratories in different regions, so that the external quality control activities are more suitable for different types of experiments room.
