新冠肺炎疫情期间感控观察员制度在手术室的应用效果

 目的 探讨新冠肺炎疫情期间感控观察员制度在手术室的应用效果。方法 将感控观察员制度应用于手术室的诊疗活动中，制定针对疫情的手术室相关流程与指引，分别选取疫情期上班1周后的第1天（2月17日）和感控观察员管理制度实施1周后的第1天（2月24日），使用焦虑自评量表和穿脱防护用品评分表，调查手术室医务人员焦虑及防护用品穿脱合格情况，并比较感控观察员制度实施前后其差异。结果 共调查医务人员60名，两次发放问卷共120份，问卷回收有效率100%。实施前（2月17日）医务人员焦虑评分为（56.96±9.45）分，实施后（2月24日）医务人员焦虑评分为（35.02±6.21）分，差异具有统计学意义（t=14.878，P<0.001）。感控观察员制度实施前及实施后，不同职称医务人员焦虑评分比较，差异均具有统计学意义（均P<0.05）。制度实施前，初级医务人员焦虑评分低于中级与高级医务人员，差异均有统计学意义（均P<0.05）。不同职称医务人员感控观察员制度实施前后焦虑评分比较，差异均具有统计学意义（均P<0.001）。通过对全科在岗的50名护理人员分组进行穿脱防护用品操作考核评分，无感控观察员的A组防护用品穿脱合格率为40.00%（10/25），而有感控观察员监督指导的B组合格率达100.00%（25/25），B组合格率高于A组，差异有统计学意义（χ²=21.429，P<0.001）。结论 感控观察员制度能有效降低诊疗活动中医务人员心理焦虑并提高其穿脱防护用品的合格率。

Application efficacy of infection control observer system in operating rooms during COVID-19 epidemic period

Objective To evaluate the application efficacy of infection control observer(ICO) system in operating rooms during coronavirus disease 2019 (COVID-19) epidemic period. Methods ICO system was applied to the diagnosis and treatment activities in operating rooms, epidemic-relevant procedures and guidelines of operating rooms were formulated, on the first day (February 17) after one week of work and the first day (February 24) after one week of the implementation of ICO management system during epidemic period, anxiety as well as qualified putting on and taking off personal protective equipment(PPE) of health care workers (HCWs) in operating rooms were investigated by self-rating anxiety scale (SAS) and rating scale of putting on and taking off PPE, difference before and after the implementation of ICO system were compared. Results A total of 60 HCWs were surveyed and 120 questionnaires were issued twice, 100% of questionnaires were available. Before the implementation (February 17), anxiety score of HCWs was (56.96±9.45), after the implementation (February 24), anxiety score of HCWs was (35.02±6.21), difference was significant (t=14.878, P<0.001). Before and after the implementation of ICO system, anxiety scores of HCWs with different professional titles were all significantly different (all P<0.05). Before the implementation of system, anxiety score of HCWs with junior professional title was lower than that of HCWs with intermediate and senior professional titles, differences were both significant (both P<0.05). Anxiety scores of HCWs with different professional titles before and after the implementation of ICO system were all significantly different (all P<0.001). 50 nurses in the department were grouped to evaluate putting on and taking off PPE, qualified rate of putting on and taking off PPE in group A (without the supervision and guidance of ICOs) was 40.00% (10/25), while that in group B (with the supervision and guidance of ICOs) was 100.00% (25/25), group B was higher than that in group A , difference was significant (χ²=21.429, P<0.001). Conclusion ICO system can effectively reduce the psychological anxiety of HCWs during diagnosis and treatment activities and improve the qualified rate of putting on and taking off PPE.
