Purpose: This study aimed to characterize cancer patients presenting to the emergency department (ED) and to identify factors associated with ED length of stay (LOS) and 72-hour revisits. Methods: This retrospective study analyzed the medical records of adult cancer patients who visited the ED of a tertiary hospital in Seoul between June and November 2023. Among 21,495 ED visits, 2,225 met the inclusion criteria. Variables included general characteristics, cancer-related characteristics, and ED visit–related characteristics. Outcomes were ED LOS and 72-hour revisits. Data were analyzed using the t-test, analysis of variance, chi-square test, multiple linear regression, and logistic regression. Results: The mean age was 64.75 ± 14.85 years, and 51.0% of patients were men. Gastrointestinal cancers were the most common cancer type (49.6%), and abdominal pain was the most frequent chief complaint (17.4%). The mean ED LOS was 245.93 ± 189.79 minutes, and the 72-hour revisit rate was 5.4%. Factors associated with longer ED LOS included older age, previous ED visits, off-hours arrival, higher acuity, ambulance transport, abnormal respiratory rate, and administration of nonsteroidal anti-inflammatory drugs, acetaminophen, or opioids. Factors influencing 72-hour revisits included the absence of a do-not-resuscitate (DNR) order, abnormal systolic blood pressure, and admission. Conclusion: For older cancer patients with high acuity who visit the ED by ambulance during off-hours, early assessment of dyspnea and prior ED utilization, along with prompt symptom-based pharmacologic interventions, is recommended. At discharge, providing education tailored to the patient’s clinical condition, including DNR status, admission status, and vital signs, and ensuring early outpatient or telephone follow-up may strengthen continuity of care and reduce short-term ED revisits.
