AbstractBackground: Emergency department (ED) overcrowding is a public health crisis that affects patient care quality. Space management in the ED can affect patient flow dynamics and clinical practice. We proposed a novel design of the "emergency procedure zone" (EPZ). The purpose of the EPZ was to provide an isolated area for clinical practice and procedure teaching, to ensure a secure area with adequate equipment and monitors, and safeguard patient privacy and safety. This study aimed to analyze the impact of the EPZ on procedural practice and patient flow dynamics. Methods: This study was conducted at the ED of a tertiary teaching hospital in Taiwan. Data were collected from 1 March 2019 to 31 August 2020 (pre-EPZ period) and from 1 November 2020 to 30 April 2022 (post-EPZ period). Statistical analyses were performed using IBM SPSS Statistics software. This study focused on the number of procedures and length of stay in the emergency department (LOS-ED). Variables were analyzed using the chi-square test and Mann-Whitney U test. Statistical significance was defined as p < 0.05. Results: There were 137,141 (pre-EPZ period) and 118,386 (post-EPZ period) ED visits recorded during this period. The post-EPZ period showed a significant increase in central venous catheter insertion, chest tube or pigtail placement, arthrocentesis, lumbar puncture, and incision and drainage procedures (p < 0.001). For patients who were directly discharged from the ED, the post-EPZ period also had a higher percentage of ultrasound studies performed in the ED and a shorter LOS-ED for patients who were directly discharged from the ED (p < 0.001). Conclusions: The establishment of an EPZ in the ED has a positive impact on procedural efficiency. The EPZ improved diagnosis and disposition efficiency, shortened the length of stay, and provided benefits such as improved management, patient privacy, and teaching opportunities.
