Real-World Implementation and Evaluation of AI-Driven Clinical Decision Support in Emergency Medicine: A Systematic Review
Abstract
Background/Objectives: Emergency departments (EDs) are high-pressure environments where time-sensitive decisions, fragmented data, and operational strain create strong demand for AI-driven clinical decision-support systems (AI-CDSSs). These systems have shown promise in triage, diagnosis, risk stratification, and workflow optimization, yet real-world implementation in emergency medicine remains uneven. This systematic review aimed to synthesize the technical characteristics, clinical applications, implementation dimensions, organizational and ethical considerations, and real-world impact of AI-CDSSs in ED settings. Methods: This systematic review followed PRISMA guidance and searched PubMed, Scopus, and Embase for English-language studies published between January 2015 and February 2025. Eligible studies described AI-CDSS implementation, clinical integration, or performance evaluation in ED settings. Twenty-three studies met the inclusion criteria and were synthesized across five domains: technical characteristics, clinical applications, implementation dimensions, organizational and ethical considerations, and real-world impact. Results: Among the 23 included studies, 20 contributed to the real-world evaluation synthesis. Of these 20 studies, 8 (40%) achieved live or prospective evaluation, seven (35%) relied only on retrospective validation, four (20%) used human-centered or perception-based evaluation, two (10%) used post-implementation assessment, and one (5%) used…
