Abstract

Purpose

To determine the effect of discontinuing routine oral contrast material on emergency department (ED) length of stay (LOS), time from order to CT completion, and preliminary report turnaround time (TAT).

Methods

A HIPAA-compliant, IRB-waived, single-institution, retrospective cohort study was conducted on adult patients presenting with abdominal pain to the ED from October 2015 to April 2019. Routine oral contrast material was administered prior to July 2018 and discontinued thereafter. CT workflow (ED LOS, exam completion time, report TAT) data were analyzed in a univariate analysis before and after discontinuation of oral contrast. Pre- versus post-policy data were compared with 2-sided t tests. The primary outcome was ED LOS. Data were analyzed on a process control chart and confidence limits were adjusted using established criteria.

Results

There were 5020 included abdominopelvic CTs. After routine oral contrast material was discontinued, ED LOS (13.4 h vs 10.7 h, p < 0.001) and time from CT order to CT completion (2.7 h vs 2.1 h, p < 0.001) declined. However, control chart analysis revealed improvement in overall LOS preceded the policy change by 9 months, while improvement in time to CT completion coincided with the policy change. Preliminary report TAT increased by 4 min after the policy change (29 min vs. 33 min, p < 0.001).

Conclusions

Discontinuation of routine oral contrast material in the ED accelerated time to CT completion but had a minor non-significant effect on overall ED LOS. Much of the reduction in overall LOS likely was due to unrelated process improvements.
