Objective:To explore the application effects of 5 level national triage system(5L NTS) in emergency internal medicine in a First-class hospital at Grade 3. Methods:The patients were randomly divided into the experimental group and control group,which were classified using 5 level national triage system and traditional standard triage,respectively. The triage failure rate,waiting time and satisfaction of patient in two groups were observed. Results:The triage failure rates of the experimental group and control group were 1.0% and 9. 2%,respectively,the difference of which was statistically significant(P <0. 05). The average waiting time of the experimental group and control group were(7. 44 ±7. 00) min and(10. 12 ±9. 44) min,respectively,the difference of which was statistically significant(P<0. 05). The satisfaction during waiting,overall hospital medical service satisfaction and physician service satisfaction in experimental group were significantly higher than those in control group(P<0. 05 to P<0. 01). Conclusions:Five level national triage system can effectively reduce the nurse triage failure rate and incidence of adverse event, shorten the waiting time of patient,and improve the patients’satisfaction.%目的：：探讨5级国际预检系统(5L NTS)在三级甲等医院急诊内科中实际应用效果。方法：采用随机抽样,观察组依据5L NTS标准进行分诊,对照组采用传统标准分诊,分别观察并比较2组间患者分诊失误率、候诊等候时间及就诊满意度。结果：观察组患者分诊失误率为1.0%,对照组为9.2%,2组患者分诊失误率差异有统计学意义(P<0.05)；观察组平均每例患者的候诊时间为(7.44±7.00)min,对照组为(10.12±9.44)min,2组差异有统计学意义(P<0.05)；观察组对候诊等候时间满意度、医院整体医疗服务满意度和医生诊疗服务满意度均高于对照组(P<0.05~P<0.01)。结论：5L NTS能有效降低预检护士分诊失误率,降低不良事件的发生,缩短患者候诊时间,提高了就诊满意度。
