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 (Z=-3.463, 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 ( Z=-3.566, 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 ( Z=-2.462, P<0.05) . 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.
