Sex Differences in the Utilization and Outcomes of Cardiac Valve Replacement Surgery for Infective Endocarditis: Insights From the National Inpatient Sample.


ABSTRACT: Background The data on the differential impact of sex on the utilization and outcomes of valve replacement surgery for infective endocarditis are limited to single-center and small sample size patient population. Methods and Results We utilized the National Inpatient Sample database to identify patients with a discharge diagnosis of infective endocarditis from 2004 to 2015 to assess differences in the characteristics and clinical outcomes of patients hospitalized with infective endocarditis stratified by sex. We also evaluated trends in utilization of cardiac valve replacement and individual valve replacement surgeries in women versus men over a 12-year period, and compared in-hospital mortality after surgical treatment in women versus men. A total of 81 942 patients were hospitalized with a primary diagnosis of infective endocarditis from January 2004 to September 2015, of whom 44.31% were women. Women were less likely to undergo overall cardiac valve replacement (6.92% versus 12.12%), aortic valve replacement (3.32% versus 8.46%), mitral valve replacement (4.60% versus 5.57%), and combined aortic and mitral valve replacement (0.85% versus 1.81%) but had similar in-hospital mortality rates. From 2004 to 2015, the overall rates of cardiac valve replacement increased from 11.76% to 13.96% in men and 6.34% to 9.26% in women and in-hospital mortality declined in both men and women. Among the patients undergoing valve replacement surgery, in-hospital mortality was higher in women (9.94% versus 6.99%, P<0.001). Conclusions Despite increased utilization of valve surgery for infective endocarditis in both men and women and improving trends in mortality, we showed that there exists a treatment bias with underutilization of valve surgeries for infective endocarditis in women and demonstrated that in-hospital mortality was higher in women undergoing valve surgery in comparison to men.
