23 Background: Patients with cancer receiving chemotherapy often present to the ED and require hospitalization to manage acute issues. However, little work has sought to understand characteristics associated with hospitalizations for patients with cancer receiving chemotherapy who present to the ED. Methods: As part of a quality improvement initiative, we reviewed ED visits within 30-days of patients receiving intravenous chemotherapy at Massachusetts General Hospital from October 2017-January 2018. We used descriptive statistics to compare sociodemographic and clinical factors for hospitalized and non-hospitalized patients. We used logistic regression to explore variables independently associated with being hospitalized. We also compared death rates within 6 months between groups. Results: We identified 500 ED visits during our study period, which resulted in 350 (70.0%) hospitalizations. Hospitalized and non-hospitalized patients did not differ by age (mean 64.1 vs 63.4, P = 0.61), sex (48.9% vs 51.3% female, P = 0.61), or presence of metastatic disease (71.1% vs 68.7%, P = 0.59). Hospitalized patients were more likely to have gastrointestinal (25.7% vs 20.7%) and lung (14.0% vs 11.3%) cancer; less likely to have breast cancer (7.4% vs 16.7%, P < 0.01). Hospitalized patients were more likely to come to the ED on a Thursday (15.7% vs 6.7%); less likely to come on a Wednesday (10.3% vs 19.3%, P < 0.01). On logistic regression, factors associated with higher likelihood of being hospitalized included white race (OR = 1.84, P = 0.03), and presenting with fever/cold symptoms (OR = 2.64, P < 0.01), fatigue (OR = 2.15, P = 0.04), or dyspnea (OR = 2.29, P = 0.04). Death rates within 6 months were higher for the hospitalized patients (50.0% vs 18.7%, P < 0.01). Conclusions: Patients with cancer who visited the ED within 30-days of receiving intravenous chemotherapy often require hospitalization. We identified factors associated with higher likelihood of hospitalization, including patient characteristics, presenting symptoms, and the day of the week. Our findings should inform future efforts to enhance care delivery and outcomes for patients with cancer receiving chemotherapy.
