Objective: To determine whether patient clinical and socioeconomic characte
ristics predict patient delay in coming to the emergency department (ED). M
ethods: Adult ED patients at five urban teaching hospitals were surveyed re
garding self-reported delay in coming to the ED. Delay was measured by self
-perception as well as by the number of days ill and unable to work. Patien
t socioeconomic and clinical characteristics were obtained by survey questi
onnaire and chart review. Cross-sectional analysis within a prospective stu
dy of 4,094 consecutive patients was performed using a subset of 1,920 pati
ents (84% eligible rate) to whom questionnaires were administered. Results:
Overall, 32% of the patients completing the survey reported delay in seeki
ng ED care. Of these patients reporting delay, 71% thought their problem wo
uld go a away or was not serious. Patients who were older, had higher acuit
y, or were frequent ED users reported less delay in coming to the ED, while
patients without a regular physician or who were African American reported
more delay. Perception of increased number of days ill prior to visiting t
he ED was reported by frequent ED users and those with worse baseline physi
cal function, while patients who had higher acuity reported fewer days ill
prior to coming to the ED. Conclusions: A patient's decision to delay comin
g to the ED often reflects a belief that his or her illness is either self-
limited or not serious. The decision to delay correlates with patient chara
cteristics and access to a regular physician. The correlates of delay in se
eking ED care may depend on the delay measure used. Better understanding of
patients at risk for delaying care may influence interventions to reduce d
elay.
