To characterize physicians’ practices and attitudes toward the initiation, limitation, and withdrawal of venovenous extracorporeal membrane oxygenation for severe respiratory failure and evaluate factors associated with these attitudes.
Electronic, cross-sectional, scenario-based survey.
Extracorporeal membrane oxygenation centers affiliated with the Extracorporeal Life Support Organization and the International Extracorporeal Membrane Oxygenation Network.
Attending-level physicians with experience managing adult patients receiving venovenous extracorporeal membrane oxygenation.
Five-hundred thirty-nine physicians in 39 countries across six continents completed the survey. Factors that influenced the decision to limit extracorporeal membrane oxygenation initiation included older patient age (46.9%), additional organ failures (37.7%), and prolonged mechanical ventilation (35.1%). Patient comorbidities (70.5%), patient’s wishes (56.0%), and etiology of respiratory failure (37.7%) were factors that influenced the decision to withdraw extracorporeal membrane oxygenation. In multivariable analysis, factors associated with increased odds of withdrawing life-sustaining therapies included pulmonary fibrosis, stroke, surrogate’s desire to withdraw, lack of knowledge regarding patient’s or surrogate’s wishes in the setting of fibrosis, not initiating extracorporeal membrane oxygenation in the baseline scenario, and respondent religiosity. Factors associated with decreased odds of withdrawal included practicing in an environment where it is not legally possible to make decisions against patient or surrogate wishes. Most respondents (90.5%) involved other physicians in treatment decisions for extracorporeal membrane oxygenation patients, whereas only 53.2%, 45.3%, and 29.5% of respondents involved surrogates, awake patients, or bedside nurses, respectively.
Patient and physician-level factors were associated with decision-making regarding extracorporeal membrane oxygenation initiation and withdrawal, including patient prognosis and knowledge of patient or surrogate wishes. Respondents reported low rates of engaging in shared decision-making when managing patients receiving extracorporeal membrane oxygenation.
