Objective: To explore the application effect of problem management pattern on the pre-examination triage system in emergency department. Methods: 500 emergency patients were randomly selected before and after the implementation of problem management pattern, respectively.The parameters such as detection rate of emergency critically ill patients, the waiting time of emergency critically ill patients, the patients’ satisfaction and the staff’s satisfaction were evaluated. Results: The detection rate of emergency critically ill patients, the satisfaction of patients and staff after the implementation of problem management pattern were significantly higher than that of before (P＜0.05). While the waiting time was significantly less. Conclusion: The application of problem management pattern is able to improve the detection rate of emergency critically ill patients, decrease the waiting time, improve the statistician degree of patients, their dependents and medical staff.
