Abstract: Objective to investigate the current situation of emergency pre-examination and triage for acute aortic dissection（AAD） in emergency departments of domestic general hospitals,and to provide reference for the establishment of standardized pre-examination and triage process for AAD. Methods Using convenient sampling method,613 emergency department medical staff from five regions across the country,including the eastern,southern,western,northern,and central regions,were selected as the research subjects from June to July 2022. The Current Survey of Acute Aortic Dissection based on HIRAID Evaluation Framework was used to analyze the current situation of emergency pre-examination and triage for AAD in the emergency department nationwide. Results In terms of medical history and identification of risk factors,16.80% of the emergency department medical staff said that they would use AAD related screening tools for initial triage screening. In the evaluation session,45.84% of the emergency department medical staff said that they did not actively measure the limb blood pressure of suspected patients with symptomatic typical AAD. There were significant differences in the application of screening tools related to AD,blood pressure measurement of limbs in suspected AAD patients with typical symptoms,and screening of acute coronary syndrome in patients with chest pain among different regions and different grades of hospitals（all P<0.05）. Conclusion The use rate of relevant screening tools was low in domestic general hospitals. There are significant differences in the quality of pre-examination and triage for AAD in hospitals of different regions and levels. It is necessary to establish a management mechanism suitable for pre-examination and triage of AAD in hospitals at all levels,and promote standardized management of emergency pre-examination and triage of AAD.
