Proposed section structure
This topic is best organized into a clinically oriented framework that moves from context to methods, then to practice-changing implications. A logical structure is: Highlights; Clinical context and why ECLS end-of-life decisions are uniquely difficult; Study design and survey methods; Key results, including who participates in decisions, how treatment is limited or withdrawn, and regional variation; Interpretation and clinical implications; Limitations and unanswered questions; Practical next steps for ICUs and ECLS programs; Conclusion; Funding and citation.
