O1-16-3 - The Retrospective Study for Unplanned Hospital Admission of Patients with Cancer Who Visited the Emergency Department

Abstract

Purpose: The purpose was to establish criteria to predict the need for unplanned hospital admission of patients with cancer who visited the Emergency Department (ED).Methods: The patients with cancer who visited the ED of Kishiwada Municipal Hospital from April 1, 2012 to March 31, 2013 were examined. We performed descriptive statistics and logistic regressions.Results: Of 15716 ED visits, there were 1244 ED visits (7.9%) of patients with cancer. Emergency hospitalizations were 462 cases (37.1%) and cardiopulmonary arrests on arrival were 12 cases (0.96%). The mean age was 71 years and the majority of patients were male. The most common type of cancer was lung (18.2%), followed by gastric (16.2%), and colorectal (14.5%). Patients with lung cancer or hepatic cell carcinoma, PS 2-4, comorbidity and metastasis were more likely to be admitted than counterparts. On the other hand, no significant difference was observed between the cases with and without emergency hospitalization regarding the cases of chemotherapy within 14 days, within 30 days, or the operation within 30 days. In 450 cases of the patients with metastasis, a significantly higher number of the emergency hospitalization were associated with the factors of age ≥ 76 years, altered mental status, SpO2 < 90%, WBC < 2000 /μl or WBC > 10000 /μl, Alb ≤ 2.5 g/dL, BUN ≥ 25 mg/dL, AST ≥ 100 IU/L and CRP ≥ 10 mg/dL. Multiple logistic regression models indicated that the elderly, altered mental status, hypoxia, WBC count abnormality and elevated CRP were independent predictive factors for emergency hospitalization.Conclusion: Our findings suggested that the several factors could predict the emergency hospitalization related to cancer.
