Background
The purpose of this study was to investigate the primary factors associated with inappropriate out‐of‐hours emergency department (
ED
) use by patients with nonurgent conditions.
Methods
We compared patients with nonurgent conditions who made inappropriate, out‐of‐hours
ED
visits to patients who visited an acute care hospital during daytime consultation hours between May 30 and October 16, 2014, in terms of patient characteristics and reasons for consultation. Our goal was to identify factors associated with inappropriate
ED
use, defined as an out‐of‐hours, nonurgent, and unnecessary visits.
Results
We analyzed data from 84 patients who made inappropriate use of out‐of‐hours emergency care and 147 patients who sought care during regular consultation hours. In the inappropriate use group, “desire to be cured quickly” was the most common reason. Acute upper respiratory infection, acute gastroenteritis, and primary headache comprised 51.1% of diagnoses in the inappropriate use group. One factor associated with inappropriate use was two or more previous out‐of‐hours
ED
visits (odds ratio (
OR
) 3.19; 95% confidence interval (
CI
) 1.22‐8.31) (reference: 0 visits).
Conclusions
Patients with two or more previous out‐of‐hours
ED
visits were more than three times as likely to inappropriately use the
ED
compared to patients who had not visited the
ED
at all in the past 3 years.
