Impact of gynecologic hospitalist on patient waiting time at the emergency department in Korea: A retrospective pre-post cohort study

Abstract

Objective: This study aimed to identify the impact of care and change in the consultation process given by a gynecologic hospitalist on patient waiting time in the emergency department (ED). Materials and methods: This is a pre-post study that compared patients' length of stay at the ED ten months before and after intervention by the gynecologic hospitalist in 2018. The consultation process changed from ED staff contacting the gynecologic resident (pre-intervention group) to directly contacting the gynecologic hospitalist (post-intervention group). Times elapsed from gynecologic consultation to final disposition, from gynecologic consultation to discharge, and from arrival at ED to discharge were compared between the two groups. Results: Among 945 referrals at the ED during the study period, the number of daytime weekday gynecologic consultations were 68 and 187 cases in the pre-intervention and post-intervention groups, respectively. The time elapsed from gynecologic consultation to the final disposition, the time elapsed from gynecologic consultation to discharge and the time elapsed from arrival at ED to discharge were shorter in the post-intervention group than in the pre-intervention group (median values, 98 vs. 167.5 min, 205 vs. 311.5 min, and 419 vs. 497 min; P < 0.05), and extended length of stay more than 12 h at the ED was less common in the post-intervention group than in the pre-intervention group (9.6 vs. 19.1%; P < 0.01). Conclusion: The waiting time of gynecologic patients upon admission and prolonged length of stay at ED significantly decreased after the establishment of the gynecologic hospitalist system.
