What can be done to improve diagnosis of aortic dissection?

Abstract

Aortic dissection (AD) is rare. Missed AD is a common reason for coronial investigations and civil claims for medical negligence. Recommendations include improved education, supervision and information transfer, reminders in chest pain pathways and higher rates of investigation for AD. Higher investigation rates pose risks to patients and the health system which may not be in balance with the likelihood of AD. The appropriate diagnostic yield of investigation to balance risk and benefit has not been defined. The AD detection risk score pathway has been proposed as a useful diagnostic tool but concerns about its derivation, validation and utility remain. In this paper, we try to draw together published literature and local audit data to develop recommendations about what might be done to reduce the number of missed AD cases in EDs and what the impact of higher investigation rates might be.
