Emergency Department (ED) overcrowding has become a global issue affecting the quality and timeliness of patient care. The Fast-Track system was introduced as a strategy to improve patient flow and reduce the length of stay (LOS), particularly for non-urgent cases. This literature review aimed to analyze the implementation of Fast-Track in emergency departments and its effect on patient LOS. The study employed a systematic literature review approach guided by the PRISMA framework, using databases such as PubMed, ScienceDirect, Scopus, ProQuest, and Google Scholar. Twelve articles published between 2015 and 2024 met the inclusion criteria. The results revealed that Fast-Track implementation reduced LOS by 25–40% and increased patient satisfaction without compromising care quality. Nurse-led Fast-Track models demonstrated better outcomes in efficiency and interprofessional coordination. However, challenges remain in resource allocation, standardization of protocols, and staff training. These findings highlight the importance of adopting context-specific Fast-Track policies to enhance emergency care efficiency and promote evidence-based nursing practice.
