Abstract 10020: Impact of Race on Temporal Trends in Hospitalizations and Outcomes in New York State Among Patients With Valvular Heart Diseases

Introduction: Valvular heart diseases (VHD) are a growing public health problem but effect of race on temporal changes in VHD hospitalizations, valve surgeries and hospital mortality rates is undefined. Hypothesis: Non-White patients (pts) with VHD are at higher risk of hospital mortality vs White pts. Methods: We retrospectively analyzed all inpatient hospital records obtained between 1983-2012 from the New York State Statewide Planning and Research Cooperative System database with a primary or secondary ICD-9 code for VHD and racial self-classification (n=2,443,056). Linear regression was used to evaluate temporal changes in numbers of valve hospitalizations and valve surgeries performed among racial groups; ANOVA, χ2 and t-tests were used, as appropriate, to compare subgroup differences on baseline clinical characteristics and lengths of stay; logistic regression (age, gender-adjusted) compared risk of hospital mortality by race. Results: During the 30-yr interval, proportions of non-White (predominant...
