Study on protective conditions of health care workers during spread of severe acute respiratory syndrome

目的 了解医务人员在传染性非典型肺炎流行期间的个人防护状况和防护效果。方法 采用整群抽样方法抽取广东省 9家医院 ,用问卷调查方式对其中接触过传染性非典型肺炎病人的 16 4 5名医务人员进行调查。结果 戴 <12层口罩的医务人员的感染率高于戴≥ 12层者 (χ2 =14 32 8,P <0 0 1) ;使用衣帽一体隔离服比使用衣帽分体的隔离服的医务人员的感染率低 (χ2 =13 5 4 6 ,P <0 0 1) ;穿 1层隔离服的医务人员的感染率明显高于穿 1层以上者 (χ2 =2 0 6 5 9,P <0 0 1) ;戴眼罩的医务人员的感染率明显低于未戴眼罩者 (χ2 =6 6 92 4 ,P <0 0 1) ;戴手套的感染率明显低于未戴手套者 (χ2 =30 814 ,P <0 0 1) ;使用非接触式洗手装置的医务人员的感染率低于使用接触式洗手装置者 (χ2 =19 2 83,P <0 0 1)。结论 建议医务人员采取严格的个人防护措施。

Objective To evaluate individual protection conditions of health care workers in the hospital.Methods Cross-sectional survey was carried out in 9 hospitals in Guangdong province.Hospital staff in contact with SARS patients were investigated with questionnaires.Results The infection rate of hospital care workers who wearing less 12 layers masks was higher than that of those with more 12 layers masks (χ 2=14 328, P <0 01).The infection rate of hospital care workers wearing gowns with helmets together was relatively lower than that of those with gowns with helmets separately (χ 2=13 546, P <0 01).The infection rate of hospital care workers wearing one piece of gown higher than that of those wearing more than one piece of gowns (χ 2=20 659, P <0 01).Wearing goggles had a lower risks than without wearing goggles (χ 2=66 924, P <0 01).The infection rate of hospital care workers wearing gloves was lower than that of those without wearing gloves (χ 2=30 814, P <0 001).The infection rate of hospital care workers using induction equipment was lower than that of those using touch equipment (χ 2=19 283, P <0 01).Conclusion In order to protect health care workers,strict protective measures were essential.
