目的:探讨叙事视频联合回授法对专职陪护人员预防误吸知信行水平的影响。方法:采用便利抽样法选取某三级甲等医院专职陪护人员为研究对象，2018年7—8月将89名专职陪护人员设为对照组，2018年10—11月将76名专职陪护人员设为观察组。对照组采用常规健康宣教，观察组在对照组的基础上采用叙事视频联合回授法进行误吸预防的宣教。比较两组专职陪护人员预防误吸的知识、态度、行为得分。结果:观察组的知识得分为44（37，49）分，高于对照组的39（31，45.5）分，差异有统计学意义（n Z=-3.463，n P<0.01）。观察组的态度得分为50（45，54）分，高于对照组的44（44，52）分，差异有统计学意义（n Z=-3.566，n P<0.01）。观察组的行为得分为47（41，51）分，高于对照组的41（35，53）分，差异有统计学意义（n Z=-2.462，n P<0.05）。n 结论:叙事视频联合回授法是一种有效的健康宣教形式，有助于提高专职陪护人员预防误吸的知识、态度、行为水平及临床照顾能力。“,”Objective:To explore the effect of narrative video combined with teach-back method on full-time caregivers' knowledge, attitude and practice level of preventing aspiration.Methods:The convenient sampling method was used to select full-time caregivers from a ClassⅢ Grade A hospital as the research objects. A total of 89 full-time caregivers from July to August 2018 were set as the control group, and 76 full-time caregivers from October to November 2018 were set as the observation group. The control group adopted conventional health education, while the observation group adopted narrative video combined with teach-back method to carry out aspiration prevention education on the basis of the control group. The scores of knowledge, attitude and practice of the two groups were compared.Results:The knowledge score of the observation group was 44 (37, 49) , higher than 39 (31, 45.5) of the control group, and the difference was statistically significant n (Z=-3.463, n P<0.01) . The attitude score of the observation group was 50 (45, 54) , which was higher than 44 (44, 52) of the control group, and the difference was statistically significant (n Z=-3.566, n P<0.01) . The practice score of the observation group was 47 (41, 51) , which was higher than 41 (35, 53) of the control group, and the difference was statistically significant (n Z=-2.462, n P<0.05) .n Conclusions:The narrative video combined teach-back method is an effective form of health education, which helps to improve knowledge, attitude, behavior levels of preventing aspiration and clinical care ability of full-time caregivers.
