Background: The use of EDs has significantly increased, and a majority of this increase is attributed to non-urgent visits, which has negative impacts. We aim to explore the frequency of non-urgent emergency department (ED) visits and to identify risk factors for non-urgent ED visits. Methods: This retrospective, the record-based study was conducted at a tertiary hospital in Samsun province of Turkey. The records of all adult patients who visited to the ED between January 1 and December 31, 2017, were included in this study. All emergency department visits were evaluated according to age, gender, time of visit, means of arrival, ICD diagnostic codes, and the number of repeated non-urgent ED visits. The number of ED visits was 87,528 for the year 2017. Results: The non-urgent emergency visit rate was 9.9%. According to binary logistic analysis, non-urgent visits were associated with young age (OR = 2.75), female gender (OR = 1.11) and non-ambulance transportation (OR = 9.86). The prevalence of non-emergent visits was very similar between weekends and weekdays but was significantly higher in work hours on weekdays than non-work hours (p<0.001). The most frequent diagnostic code was “Pain, unspecified” (R52) and the rate of repeated visits was 14.8% of non-urgent ED visits. Conclusions: Harmonization of various databases at the primary level in terms of design and connectivity and integration with hospital information systems will contribute to the identification of problems and the generation of solutions. The next step is establishing an integrated health care system that can benefit emergency care organizations in Turkey.
