Length of Stay (LOS) in the Emergency Department

Abstract

Background: Length of Stay (LOS) in the Emergency Department (ED) is a key indicator of healthcare efficiency and patient flow management. Prolonged LOS is strongly linked to ED overcrowding, delays in diagnosis and treatment, increased complication rates, and reduced patient satisfaction. Multiple factors including patient demographics, clinical presentation, diagnostic processes, consultation delays, and system-related limitations contribute to extended LOS, especially in resource-limited environments. Understanding these determinants is essential for improving emergency care delivery and optimizing patient outcomes.
