南京市结核病防治医务人员医用防护口罩佩戴行为分析

Analysis of wearing behavior of medical respirator among tuberculosis control health care workers in Nanjing

目的了解南京市结核病防治医务人员医用防护口罩佩戴情况及其影响因素。方法采用自填问卷,对南京市7所结核病定点医院的结核病防治医务人员进行调查,收集佩戴行为及相关影响因素信息。采用多因素logistic回归模型进行分析。结果有效调查187人,口罩防护认知总正确率为74.56%。面对传染性患者/标本时,60.43%(113人)选择医用防护口罩,其中仅有46.90%(53人)在佩戴时进行口罩密合性测试,医用防护口罩佩戴正确率为28.34%。多因素非条件logistic回归分析显示,市级医疗机构(OR=2.205,95%CI:1.082~4.493)、年龄>35岁(OR=2.312,95%CI:1.097~4.872)为正确佩戴医用防护口罩的危险因素;防护认知(OR=0.260,95%CI:0.069~0.980)、培训教育(OR=0.460,95%CI:0.217~0.976)为保护性因素。结论南京市结核病定点医院医务人员医用防护口罩佩戴现状不容乐观,应有效落实培训管理制度,加强职业防护的引导与支持,提高职业防护与感染控制认知。

Objective To investigate the medical respirator wearing situation and its influence factors among tuberculosis（TB）control health care workers（HCWS）in Nanjing.Methods TB control HCWS in 7 fixed-point hospitals in Nanjing were investigated by self-administered questionnaire survey,information on wearing behaviors and influential factors were collected Multivariate logistic regression model was used for analysis.Result A total of 187 HCWS were investigated validly,the total accuracy of wearing protection respirator was 74.56%.There were 60.43%（113）HCWS wearing medical respirators when contacting with infectious patients or facing sputum specimens,only 46.90%（53 subjects）did fit testing.The right wearing rate for medical respirator was 28.34%.Multivariate logistic regression analysis showed that the municipal medical institution（OR=2.205,95%CI=1.082-4.493）,age older than35 years（OR=2.312,95%CI=1.097-4.872）were risk factors for proper using medical respirators.Cognitive level（OR=0.260,95%CI=0.069-0.980）and training（OR=0.460,95%CI=0.217-0.976）were protective factors.Conclusion The current situation of medical respirator wearing among HCWS in fixed-point tuberculosis hospitals in Nanjing is not optimistic.Training management system should be implemented effectively.The guidance and support for HCWS should be strengthened to improve the cognitive level of occupational protection and infection control.
