Application of PDCA Cycle in Tracheal Intubation Training for Emergency Medicine Residents

Tracheal intubation is a critical but technically demanding procedure in emergency airway management. Junior emergency medicine residents often struggle to achieve proficiency, leading to increased risks of complications. This study evaluates the effectiveness of a Plan-Do-Check-Act (PDCA) cycle-based training program in improving intubation skills. The study was conducted in the emergency department of a tertiary teaching hospital. Residents performing intubations in 2023 with conventional training served as the control group, while those trained with the PDCA model in 2024 formed the intervention group. The PDCA program included structured lectures, high-fidelity simulation, supervised clinical practice, and iterative feedback. Primary outcomes were first-attempt success rate and intubation completion time. Secondary outcomes included incidence of local airway trauma, extubation failure due to airway injury within 72 hours, and resident satisfaction. This study aims to provide evidence that PDCA-based training can enhance procedural competency, safety, and learner satisfaction in emergency airway management.
