Inter-facility transfer of patients with type A aortic dissection (AD) requires timely and efficient medical care. However, the quality of care provided during the transfer remains largely unknown. This study aimed to evaluate the quality of care of patients with type A AD who underwent inter-facility transfer at a single medical center in Taiwan. This retrospective cohort study enrolled all patients with type A AD who underwent inter-facility transfer between January 2017 and December 2019. Patients with complete transfer records and electronic medical charts in the emergency department (ED) were included. Patients who experienced a cardiac arrest episode before transfer were excluded due to poor outcomes. Patients were divided into two groups based on their hemodynamic status: the ideal group with values within the desirable range heart rate (HR) <60 bpm and systolic blood pressure (SBP): 100–120 mmHg and the control group with values out of range (HR >60 bpm or SBP <100 or >120 mmHg) before the transfer. We conducted an analysis of variations of hemodynamic status after the transfer. Among the 378 patients transferred with type A AD, 36 (31.9%) in the ideal group and 255 (96.2%) in the control group experienced hemodynamic deterioration after the transfer. In the ideal group and control group, the presence of nurses and emergency physicians assisting in the transfer accounted for only 6.2% and 7.95%, respectively. The ideal group had a significantly better survival outcome (adjusted OR (aOR): 1.25, 95%confidence interval (CI): 1.12–2.45) compared to the control group. The quality of inter-facility transfer in patients with type A AD is inadequate. Hemodynamic deterioration should be managed by ambulance crews during the transfer.
