An auditable conditional-strategy framework for open-ended decision-making in complex lung cancer

The article introduces MedGPT Clinical Explorer (MCE), a conditional‑strategy framework designed to aid complex lung cancer decision‑making by explicitly mapping patient conditions to pathway eligibility, deferral, and redirection. In a study with 250 physicians across 98 institutions, MCE‑assisted strategies achieved higher Admissible Pathway Attainment Scores (APAS) than unaided or retrieval‑reference approaches, indicating more comprehensive inclusion of clinically relevant content and coherent links among pathways, conditions, and actions. The authors suggest that MCE’s shared decision object could improve transparency of omissions and contingencies, warranting prospective evaluation of its impact on workflow and patient outcomes.
