新型冠状病毒肺炎疫情期间个人防护用品穿脱技能培训学习曲线分析

Learning curves of putting on and taking off personal protective equipment skill training during outbreak of COVID-19

摘要:

目的 探讨医护人员快速掌握个人防护用品（PPE）规范穿脱流程的方法，为进一步规范化培训提供借鉴与参考依据。方法 某院于2020年1—2月，先后分两组对344名临床医护人员进行PPE穿脱流程技能培训。第1组为其他临床科室医护人员209名，第2组为援鄂医疗队、发热门诊、隔离病房医护人员135名。两组共同培训科目为理论知识学习、视频学习、操作培训，第2组在此基础上增加模拟训练考核、隔离病区现场教学科目，对比分析两组医护人员PPE穿脱合格率及学习曲线。结果 第2组PPE穿脱操作考试合格率高于第1组（90.37% VS 69.86%），差异有统计学意义（P<0.05）。第2组医护人员的PPE穿脱流程技能学习曲线操作9次进入稳定期，学习曲线随操作次数的增多操作正确率呈持续上升趋势，当训练操作达15次后达到熟练期；而第1组其学习曲线需操作13次才达到稳定期，进入熟练期需21次。结论 增加模拟训练考核、隔离病房现场教学科目可以缩短医护人员PPE穿脱技能学习曲线，有助于医护人员尽快掌握PPE穿脱操作技能，降低新型冠状病毒肺炎感染风险。

Abstract:

Objective To explore the method of quickly mastering the process of personal protective equipment (PPE) putting on and taking off by health care workers(HCWs), so as to provide reference for further standardized training. Methods From January to February 2020, 344 HCWs were divided into two groups and received the skill training of PPE putting on and taking off process. 209 HCWs in group 1 were from other clinical departments, 135 HCWs in group 2 were from medical team aid to Hubei, fever clinic, and isolation wards. The common training subjects of both groups were theoretical knowledge learning, video learning and manipulate training, on this basis, group 2 added simulation training examination and on-site teaching subject in isolation wards, qualified rates and learning curves of PPE putting on and taking off in two groups of HCWs were compared and analyzed. Results The qualified rate of PPE putting on and taking off in group 2 was higher than that in group 1 (90.37% vs 69.86%), difference was statistically significant (P<0.05). In group 2, the learning curve of PPE putting on and taking off process skill entered a stable period after 9 times of manipulation, correct rate of manipulation continued to rise with the increase of manipulation times; when manipulation training reached 15 times, it entered the proficiency period; in group 1, the learning curve needed 13 times of manipulation to enter the stable period, and 21 times of manipulation to enter the proficiency period. Conclusion Learning curve of PPE putting on and taking off skill of HCWs can be shortened by adding simulation training examination and on-site teaching subject in isolation wards, which is helpful for HCWs to master PPE putting on and taking off skill as soon as possible, and reduce the risk of coronavirus disease 2019 (COVID-19).
