    BackgroundEarlier studies have shown disparate cardiovascular care in homeless patients. Limited data exist on burden of infective endocarditis (IE) in homeless patients and in this study, we aimed to analyze it using a nationally representative United States population sample.MethodsData were extracted from National Inpatient Sample database from January 2000 to December 2017. Patients with endocarditis were sampled using International Classification of Diseases, 9th Revision, Clinical Modification codes of 421.0, 421.1 or 421.9 and International Classification of Diseases, 10th Revision, Clinical Modification codes of I33.0 or I33.9. Homeless patients were identified using codes of V60 and Z59. Linear regression was used for trend analysis and logistic regression was utilized to identify predictors of mortality. 1:1 propensity score (PS) matching was also done to balance confounders and outcomes were assessed in both unmatched and matched cohorts.ResultsWe found an increase in proportion of homeless patients admitted with endocarditis from 0.2% in year 2000 to 2.4% in year 2017. Mortality was not statistically significant in PS matched homeless and non-homeless cohorts (4.7% vs 6.6%, p = 0.072). There was a trend towards increased mortality in homeless endocarditis patients over our study years with lower utilization of valvular surgeries. Advanced age, alcohol abuse and admission to large hospitals were independently associated with mortality in homeless endocarditis patients.ConclusionHomeless patients have rising trend of IE and IE related mortality and also found to have low utilization of life saving valvular surgeries when compared to general population.Copyright © 2021 Southern Society for Clinical Investigation.
