Abstract
Background: Crowded emergency departments (EDs) adversely affect patient care and healthcare efficiency, leading to prolonged wait times, delayed treatments, and increased medical errors. This issue also diminishes patient satisfaction and disrupts hospital operations. In Saudi Arabia, ED overcrowding impacts response times and staff morale, highlighting the need for efficient patient flow processes to ensure timely and effective care. Objectives: The aim of this study is to identify the main bottlenecks in the workflow of Saudi Arabian EDs from patient arrival to disposition. Design: A retrospective quantitative study analyzed data from 753 patients across multiple hospitals in Saudi Arabia's EDs to identify workflow bottlenecks. Using SPSS and AMOS for data analysis, various statistical methods, including ANOVA and structural equation modeling (SEM), were employed to evaluate key performance metrics and their influence on the total length of stay (LOS). Results: The Doctor to Decision Time is the most significant bottleneck, followed by the Triage to Doctor Time. CTAS3 and CTAS4 categories experience the most significant delays across multiple stages. In addition, the default model in AMOS 29 shows an excellent fit, indicating that reducing delays in Decision to Disposition Time (estimate = 0.840) and Doctor to Decision Time (estimate = 0.442) is crucial for improving the total LOS in the ED. Conclusion: This study identifies significant inefficiencies in the ED workflow in Saudi Arabia, particularly in the Doctor to Decision Time and Triage to Doctor Time stages, and recommends streamlining consultation protocols, enhancing medication delivery, expediting lab and radiology services, and increasing staffing to improve operational efficiency and patient outcomes. Faster bed turnover reduces Decision to Disposition Time and frees up ED beds. Adequate staffing improves triage, evaluation times, and care quality. Well-trained nurses enhance patient interactions and reduce delays. Standardized guidelines ensure timely treatment. Effective communication and teamwork improve patient flow and reduce bottlenecks.
