The impact of an acute care emergency surgical service on timely surgical decision-making and emergency department overcrowding.

BACKGROUND

This study evaluated how implementation of an acute care emergency surgery service (ACCESS) affected key determinants of emergency department (ED) length of stay, and particularly, surgical decision time. Also, we analyzed how ACCESS affected ED overcrowding.

STUDY DESIGN

We conducted a before and after study of all ED patients referred to ACCESS from January 1, 2007 to June 30, 2009. ACCESS was implemented on July 1, 2008. The primary outcome was surgical decision time; the secondary outcome was a measure of overall ED overcrowding: "time-to-stretcher" for all ED patients. The control groups were patients referred to internal medicine or urology. Patients with appendicitis were studied in order to analyze the impact on patient outcomes and to determine barriers to efficient ED patient flow.

RESULTS

Of 2,510 patients, 1,448 patients were pre-ACCESS, and 1,062 were after ACCESS implementation. Implementation of ACCESS was associated with a 15% reduction in surgical decision time (12.6 hours vs 10.8 hours, p < 0.01). During the same period, there were no significant changes in decision time for our control groups. Also, the mean time-to-stretcher for all ED patients decreased by 20%. In patients with appendicitis, we found that patient flow could be further improved by a timely request for surgical consultation and expedited imaging. Finally, we found that patients with nonperforated appendicitis with a fecalith on CT imaging were more likely to suffer perforation while waiting for surgery.

CONCLUSIONS

ACCESS reduced surgical decision time for surgical patients. Also, ACCESS improved overall ED crowding, as measured by time-to-stretcher for ED patients. Further improvements could be made by improving time to imaging. Patients referred for nonperforated appendicitis with a fecalith on CT should have expedited surgery.
