Key Factors in Decision Making for ECLS: A Binational Factorial Survey

Area of Science:

• Cardiology
• Intensive Care Medicine
• Medical Ethics

Background:

• Extracorporeal life support (ECLS) is a critical intervention for severe cardiopulmonary failure.
• ECLS carries significant risks, necessitating careful patient selection for initiation and withdrawal.

Purpose of the Study:

• To identify patient factors influencing the decision to initiate ECLS.
• To determine factors guiding the withdrawal of ongoing ECLS treatment.

Main Methods:

• A factorial survey was conducted with 420 physicians across 111 hospitals in Switzerland and Germany.
• Physicians evaluated 5 vignettes each for ECLS initiation and withdrawal scenarios.
• Mixed-effects regression models with random intercepts were used for analysis.

Main Results:

• Patient age, treatment costs, therapeutic goals, comorbidities, and neurological outcome significantly impacted ECLS initiation decisions.
• Age, duration of ECLS, discontinuation criteria, patient condition, comorbidities, and neurological outcome influenced withdrawal decisions.
• Patient age and neurological outcome were the most significant factors in both initiation and withdrawal decisions.

Conclusions:

• Physician decision-making regarding ECLS initiation and withdrawal is complex.
• Patient age and neurological status are the paramount factors guiding these critical decisions.
• Findings offer insights for refining ECLS management protocols and ethical considerations.
