Abstract
We assessed the relationship between emergency department (ED) crowding and delays in care in patients presenting with abdominal pain who receive abdominal computed tomography (CT). Prospective cohort study of adults who presented over a 1-year period to 2 urban academic EDs with abdominal pain and received CT. Each subject had 3 validated crowding measures assigned at enrollment (ED census, waiting room number, number of admitted patients). These were normalized to quartiles to signify least to most crowded. The Cuzick test was used for trend and log-linear regression and tested the association between ED crowding and time from triage to CT read. The time interval was further decomposed into triage to room, room to CT order, and order to CT read times. The adjusted analysis controlled for age, sex, race, pain score, time of day, triage level, and site. 767 patients were enrolled (mean age, 44 +/- 17 years; 61% female; 60% black). Median time from triage to CT read was 375 minutes (interquartile range [IQR], 276-497). Individual time intervals included triage to room (46 minutes [IQR, 16-111]), room to CT order (83 minutes [IQR, 38-151]), and order to CT read (203 minutes [IQR, 138-375]). Across waiting room quartiles, triage t...Continue Reading
