Objective:To explore the effect of competency-oriented task-driven teaching method in experimental teaching of emergency and critical care nursing,and to provide basis for improving the quality of nursing teaching.Methods:A total of 40 nurses from the Fifth Affiliated Hospital of Zunyi Medical University were randomly divided into control group and observation group.The control group adopted the conventional teaching method,while the observation group adopted the competency-oriented task-driven teaching method.The mastery degree of emergency and critical care,nursing teaching achievement and nursing teaching quality were compared between the two groups.Results:After teaching,the total mastery rate of emergency and critical care in the observation group was 95.00%,which was significantly higher than that in the control group(65.00%),with statistically significant difference(χ2=5.625,P<0.05).After teaching,the scores of each dimension in the observation group were significantly higher than those in the control group(t=4.809,7.220,2.455,3.776,6.797,4.757;P<0.05).After teaching,the scores of each dimension of the nursing teaching quality scale of emergency and critical care in the observation group were significantly higher than those in the control group,and the difference was significant(t=6.755,6.509,4.506,6.971,6.602,6.406;P<0.05).Conclusion:The application of the competency-oriented task-driven teaching method in the experimental teaching of emergency and critical care can improve the mastery of emergency and critical care work by practical nurses,improve the nursing teaching results and the quality of teaching.
