Optimizing processes of care and time to diagnosis in acute aortic dissection patients in a chest pain center by implementing a multidisciplinary cooperative first aid mode - A quality improvement report.

OBJECTIVE This study aimed to explore the effectiveness of a multidisciplinary cooperative first aid model in the process of establishing a chest pain center specializing in acute aortic dissection (AD). DESIGN A quality improvement report. METHODS A total of 142 patients with acute aortic dissection treated before and after the optimization of the chest pain center process in our hospital were included. According to their admission time: the group before the optimization process was designated as the control group (66 cases) and the group after the optimization process was the intervention group (76 cases). The control group received conventional emergency treatment, while the intervention group received treatment through a multidisciplinary cooperative first aid model. The treatment times for both groups were compared: the time from first medical contact(FMC) to completion of an electrocardiogram (ECG), the diagnosis time, and the time spent in the emergency department. RESULTS The research findings revealed that the intervention group had significantly shorter times for FMC-to-ECG, diagnosis time, and emergency stay compared to the control group (P < 0.001). CONCLUSION Our findings indicate that by optimizing the multidisciplinary cooperative first aid model and procedures, the treatment of patients has indeed been effectively ensured, achieving safety outcomes. IMPLICATIONS FOR CLINICAL PRACTICE For chest pain centers, we suggest that to use multidisciplinary cooperative first aid model to get repaid and definite diagnosis of various causes of chest pain. A bedside transthoracic echocardiography is recommended to use in order to identify AD before proceeding with further treatment.
