Explaining the Process of Determining Futility Increases Lay Public Acceptance.

Area of Science:

• Medical Ethics
• Public Health Policy
• Clinical Decision-Making

Background:

• National guidelines exist for conflict resolution regarding potentially inappropriate medical interventions.
• Understanding public perception of withholding such treatments is crucial for guideline implementation.

Purpose of the Study:

• To assess the association between knowledge of a process-based conflict resolution approach and public perception of withholding medically inappropriate interventions.
• To evaluate the impact of process information on the perceived appropriateness and emotional response to such medical decisions.

Main Methods:

• A nationwide survey with 1,191 participants presented two intensive care unit vignettes (advanced cancer, multiorgan failure).
• Participants were randomized to receive or not receive information about a detailed conflict resolution process (e.g., second opinions, ethics consultation).
• Primary outcome: perceived appropriateness of withholding treatment; Secondary outcome: negative emotional reaction.

Main Results:

• Providing detailed process information increased the perceived appropriateness of withholding treatment by approximately 10 percentage points in both vignettes.
• This association remained significant after adjusting for covariates (chemotherapy: PR 1.13; dialysis: PR 1.17).
• Process information was not significantly associated with negative emotional responses to the cases.

Conclusions:

• Informing the public about process-based conflict resolution strategies enhances acceptance of medical futility determinations.
• These findings support the adoption of established national consensus statements on managing end-of-life care conflicts.
• The study highlights the importance of transparent processes in building public trust regarding difficult medical decisions.
