Abstract: Objective: To design an integrated information-based triage and registration system in the emergency department based on Business Process Reengineering (BPR) theory and explore its effects. Methods: Constructing an integrated information-based triage and registration system in the emergency department through literature review and group meeting discussion. At the same time, opened the electronic diagnosis and treatment card application authority, redesigned the triage registration list, and improved the function of the triage information system. Convenience sampling method was used to select patients who visited the emergency department of a tertiary grade A hospital in Changsha from January to December 2022 as the research subjects. Six hundred patients visiting the emergency department from January to June 2022 were included in the control group, and another 600 patients from July to December 2022 were included in the experimental group. The experimental group adopted the integrated information-based triage and registration process, while the control group adopted the conventional one. The time spent in each link of triage and registration (triage time, registration time, information entry time, total time) and patient and staff satisfaction were compared between the two groups, and semi-structured interviews were used to collect staff opinions on the integrated information-based triage and registration process. Results: The time spent on triage, registration, information entry, and the total time for triage and registration in the experimental group were shorter than those in the control group (P<0.001). Both the patient satisfaction and staff satisfaction in the experimental group was significantly higher than those in the control group (P<0.05). Conclusion: The application of the integrated information-based triage and registration system reduces the time consumed in each link of patient triage and registration, improves the overall patient satisfaction and their treatment experience as well as staff efficiency and satisfaction.
