P1574Predictors of mortality in hospitalized atrial fibrillation patients with cancer

Abstract

Abstract Background Recent reports indicate an important interplay between Atrial fibrillation (AF) and cancer. There is little information regarding the outcomes of these patients. Hence, we performed a study to identify predictors of in-hospital mortality to help guide goals of care discussions. Methods The Nationwide Inpatient Sample was used to identify patients with a diagnosis of cancer, who were found to have AF from 2002–2014. Trend rate, patients' and hospital characteristics along with in-hospital complications and predictors of in-hospital mortality were assessed. Backward stepwise elimination technique was used to fit the multivariate regression model. Results Over the 13-year study period, 12,410,290 (national estimate) patients with a cancer diagnosis were identified. 1,013,735 had AF, and 10.2% of the AF patients with cancer died while hospitalised. A variety of comorbidities, in-hospital procedures and in-hospital complications increased the odds of in-hospital mortality in these patients. Also, weekend admissions, elective admissions, and rural hospitals in comparison to urban teaching and non-teaching hospitals were associated with higher in-hospital mortality. Conclusion Stroke, myocardial infarction, pulmonary embolism, deep venous thrombosis, acute kidney injury, congestive heart failure, sepsis, and cardiogenic shock are most significant predictors of in-hospital mortality in AF patients with cancer.
