Contemporary predictors of readmission outcomes in patients with infective endocarditis: analysis from a national readmission database

Abstract Background/Introduction Infective endocarditis (IE) remains a serious illness that is associated with remarkable morbidity and mortality in the United States (US). There are limited studies that investigated predictors of 30-day readmission risk in this population. Purpose We aimed to perform a contemporary analysis to investigate predictors of 30-day readmission in IE patients in the US. Methods We used the 2017 national readmission database to identify index admissions among adults (age ≥18) with the diagnosis of IE. Appropriate International Statistical Classification (ICD-10) codes were used to identify patients with IE. Primary outcome of interest was 30-day readmission, and hospital cost was the secondary outcome. Results Out of 49,692 admissions for IE, 5,743 (11.6%) patients were readmitted within 30 days. Patients who had 30-day readmission were younger (55±20 vs 61±19 years, P
