Evaluating a closed-loop tracking and management model in determining aortic dissection diagnosis rates in a selected...

This study aimed to evaluate the effectiveness of a closed-loop tracking and management model in reducing the rates of missed and misdiagnosed aortic dissection (AD) in the emergency department (ED).

Quality improvement report.

Using HIRAID as the guiding framework, a quality improvement program was implemented. The quality improvement team developed a closed-loop tracking and management model for AD, which included symptom-based screening and tracking, blood pressure screening of the limbs as an auxiliary method, and a diagnostic and treatment information tracking platform. The closed-loop tracking and management model for AD was applied in the ED of a tertiary hospital in Wuhan. Blood pressure measurements of the extremities were taken when patients presented with risk symptoms of AD for further screening. Additionally, misdiagnosed cases were continuously tracked.

After the application of closed-loop tracking and management model, the rate of misdiagnosed AD decreased from 5.16% in 2019 to 1.23% in 2023.

Closed-loop tracking and management model could help reduce the rates of misdiagnosed AD in the ED.
