Abstract: Objective: To explore the effect of information management in the whole process of blood sampling in emergency department to ensure patient safety. Methods: Purpose sampling was used to select 874 patients admitted to the emergency department for resuscitation and their data were collected for statistical analysis. Patients who visited the resuscitation area in the fourth quarter of 2021 were designated as the control group (n=438), and patients who visited in the fourth quarter of 2022 were designated as the experiment group (n=436). Before the implementation, the group adopted routine blood collection process management, and after the implementation, the group adopted whole-process blood collection information management. The daily number of patients receiving resuscitation and the incidence of adverse events, the timeliness of the delivery of blood samples for blood routine, blood type and blood biochemistry and the delayed specimen delivery rate of the two groups were gathered and compared. Results: After the application of the information management, shorter detention time between patient admission and sample delivery, and a lower rate of delayed specimen delivery. Besides, the experiment group also showed faster results than the control group. All of the differences between the two groups were found to be statistically significant (P<0.05). Conclusion: The whole process information management mode in the emergency department can effectively improve the efficiency of tests, reduce the incidence of adverse events and ensure patient safety.
