目的:了解新型冠状病毒肺炎疫情期间武汉方舱医院隔离病房工作人员穿脱个体防护装备认知状况，为提供医院感染防护培训提供科学依据。方法:采用问卷星的形式调查武汉方舱医院隔离病房工作人员(402名)穿脱个体防护装备认知状况，调查表包括穿防护装置，脱防护装置和手部卫生消毒等14项相关量表。结果:非医务工作者的量表总评分48.82±9.65，低于医生的量表总评分55.46±1.29，低于护士的量表总评分55.0±2.36，n P<0.05，差异有统计学意义；非医务工作者的量表评分中的14个项目评分均低于医生、护士，n P<0.05，差异有统计学意义；医生、护士和医技人员之间比较，量表评分差异均无统计学意义。非医务工作者后期工作时的量表总分55.23±3.26，明显高于前期工作时的量表总分44.50±10.14，n P<0.001，差异有统计学意义。护士、医技人员在后期工作时的量表总分高于前期工作，差异有统计学意义；医生后期工作时的量表总分与前期工作时的总分比较，差异无统计学意义。n 结论:武汉方舱医院中，非医务工作者对穿脱个体防护装备的认知水平低于医生护士，加强对穿脱个体防护装备培训和学习，能改善认知水平。“,”Objective:To investigate the cognitive level of wearing and removing personal protective equipment in COVID-19 isolation wards of Wuhan n Fangcang shelter hospital, and provide the scientific basis for the training of hospital protection.n Methods:Cognitive level of wearing and removing personal protective equipment in Wuhan Fangcang shelter hospital were investigated by using a questionnaire which included 14 related scales, including putting on and off protective equipment, hand hygiene disinfection and so on.Results:The total scale score of non-medical workers was 48.82±9.65, which was lower than the total scale score of doctors (55.46±1.29) and nurses (55.0±2.36), n P<0.05. The each score of 14 items in the scale of non-medical workers was all lower than those of doctors and nurses (n P<0.05). There were no significant differences in scale scores among doctors, nurses and medical technicians. The total score of the scale of non-medical workers in later period was 55.23±3.26, which was significantly higher than the total score of 44.50±10.14 in previous period,n P<0.001. The total score of nurses and medical technicians in the later period was higher than those in the previous period, and the difference was statistically significant. There was no significant difference between the total score of the scale in the later period and that in the previous period.n Conclusions:The cognition level of non-medical workers on wearing and removing personal protective devices was lower than those of doctors and nurses, strengthening the practice could improve cognition.
