Development of a Multidisciplinary Decision Support Instrument for Patients With a Ruptured Abdominal Aortic Aneurysm Based on Multidisciplinary Codified Peer Expertise: A Discrete Choice Experiment

A clinical DSI was developed, based on codified multidisciplinary peer expertise, to support real-life medical decision-making during acute treatment planning for rAAA. Three parameters that are underreported in previous scoring systems (patient's frailty, estimated life expectancy, and patient's desire to be operated) were considered most important for treatment decision.Clinical ImpactTreatment decisions for ruptured abdominal aortic aneurysm patients are time-critical and morally complex, often made with limited clinical information and without multidisciplinary consultation. This study describes the development of a transparent decision-support instrument (DSI) based on multidisciplinary peer expertise. By reflecting decision logic and criteria considered important by experts, the DSI may contribute to more consistent decision-making and help identify patients for whom palliative care might be more appropriate. Further validation is required to determine its clinical utility, although this approach may support clinicians in urgent, morally complex scenarios.
