Factors associated with the undertriage of patients with abdominal pain in an emergency room.

ABSTRACT

INTRODUCTION: The triage process lasts for a very short time, which can result in over-triage and under-triage. Studies have explored factors related to under-triage among trauma patients. In Korea, the clinical characteristics and severity of cases of under-triaged patients have been investigated. However, there is limited research on the under-triage of patients experiencing abdominal pain. Therefore, this study aimed to determine the under-triage rate of emergency department (ED) patients with abdominal pain, as well as the factors associated with their under-triage. METHODS: The participants of this retrospective cohort study were 3,030 adult patients at a single tertiary hospital in Korea, who were brought to the ED for abdominal pain as the chief complaint. Participants' general characteristics, pain-related information, and environmental information were obtained from their electronic medical records. RESULTS: The under-triage rate of ED patients with abdominal pain was 31.0%. Factors related to the under-triage of these patients were sex, age, visit route, time from the onset of the pain to the visit, location of pain, and intensity of pain. CONCLUSION: These findings provide a foundation for the understanding and mitigation of under-triage in EDs through the identification of factors associated with under-triage in patients with abdominal pain.
