Effect of Publicly Reported Aortic Valve Surgery Outcomes on Valve Surgery in Injection Drug- and Non-Injection Drug-Associated Endocarditis.

ABSTRACT: BACKGROUND:Injection drug use-associated infective endocarditis (IDU-IE) is rising and valve surgery is frequently indicated. The effect of initiating public outcomes reporting for aortic valve surgery on rates of valve surgery and in-hospital mortality for endocarditis is not known. METHODS:For an interrupted time series analysis, we used data from the National Inpatient Sample, a representative sample of United States inpatient hospitalizations, from January 2010 to September 2015. We included individuals aged 18-65 with an International Classification of Diseases, Ninth Revision (ICD-9) diagnosis of endocarditis. We defined IDU-IE using a validated combination of ICD-9 codes. We used segmented logistic regression to assess for changes in valve replacement and in-hospital mortality rates after the public reporting initiation in January 2013. RESULTS:We identified 7322 hospitalizations for IDU-IE and 23 997 for non-IDU-IE in the sample, representing 36 452 national IDU-IE admissions and 119 316 non-IDU admissions, respectively. Following the implementation of public reporting in 2013, relative to baseline trends, the odds of valve replacement decreased by 4.0% per quarter (odds ratio [OR] 0.96, 95% confidence interval [CI] 0.93-0.99), with no difference by IDU status. The odds of an in-patient death decreased by 2.0% per quarter for both IDU-IE and non-IDU-IE cases following reporting (OR 0.98, 95% CI 0.97-0.99). CONCLUSIONS:Initiating public reporting was associated with a significant decrease in valve surgery for all IE cases, regardless of IDU status, and a reduction in-hospital mortality for patients with IE. Patients with IE may have less access to surgery as a consequence of public reporting. To understand how reduced valve surgery impacts overall mortality, future studies should examine the postdischarge mortality rate.

Project description:Background Infective endocarditis ( IE ) after transcatheter aortic valve replacement is a devastating complication associated with a high mortality. Our objective was to determine the impact of cardiac surgery (CS) and antibiotics ( IE - CS ) compared with medical treatment with antibiotics only ( IE - AB x) on 1-year mortality in patients developing IE after transcatheter aortic valve replacement. Methods and Results Patients developing IE after transcatheter aortic valve replacement were included in this retrospective analysis. All-cause 1-year mortality was the primary end point. A total of 20 patients underwent IE - CS compared with 44 patients treated by IE - AB x. In this unmatched cohort, patients treated by IE - AB x were older ( P=0.006), had a higher Society of Thoracic Surgeons score ( P=0.029), and more often had severe chronic kidney disease ( P=0.037). One-year mortality was not different between groups ( IE -CS versus IE-ABx, 65% versus 68.2%; P=0.802). The rate of any complication during treatment was higher in the IE - CS group ( P=0.024). In a matched cohort, baseline characteristics were not significantly different. All-cause 1-year mortality was not different between groups ( IE -CS versus IE-ABx, 65% versus 75%; P=0.490). A Cox regression analysis revealed any indication for surgery (hazard ratio, 6.20; 95% confidence interval, 1.80-21.41; P=0.004), sepsis on admission (hazard ratio, 4.03; 95% confidence interval, 1.97-8.24; P<0.001), and mitral regurgitation ?2 (hazard ratio, 2.91; 95% confidence interval, 1.33-6.37) as factors associated with 1-year mortality. Conclusions In patients developing IE after transcatheter aortic valve replacement, mortality was predicted by the severity of IE and concomitant mitral regurgitation. In this small, and therefore statistically limited, but high-risk patient cohort, CS provided no significant mortality benefit compared with medical therapy. Individual decision making by a "heart and endocarditis team" is necessary to offer those patients the most reasonable treatment option.

Project description:ObjectivesThis study sought to evaluate the incidence and outcomes of endocarditis after transcatheter aortic valve replacement (TAVR).BackgroundData about endocarditis after TAVR are limited.MethodsThe study investigated Medicare patients who underwent TAVR from 2012 to 2017 and identified patients admitted with endocarditis during follow-up using a validated algorithm. The main study outcome was all-cause mortality.ResultsOf 134,717 patients who underwent TAVR, 1868 patients developed endocarditis during follow-up (incidence 0.87%/year), with majority of infections (65.0%) occurring within 1 year. Incidence of endocarditis declined in recent years. The most common organisms were Staphylococcus (22.0%), Streptococcus (20.0%), and Enterococcus (15.5%). Important predictors for endocarditis were younger age at TAVR, male sex, prior endocarditis, end-stage renal disease, repeat TAVR procedures, liver and lung disease, and post-TAVR acute kidney injury. Thirty-day and 1-year mortality were 18.5% and 45.6%, respectively. After adjusting for comorbidities and procedural complications, endocarditis after TAVR was associated with 3-fold higher risk of mortality (44.9 vs. 16.2 deaths per 100 person-years; adjusted hazard ratio [aHR]: 2.94; 95% confidence interval [CI]: 2.77 to 3.12; p < 0.0001). End-stage renal disease (aHR: 2.12; 95% CI: 1.72 to 2.60), endocarditis complicated by cardiogenic shock (aHR: 2.50, 95% CI: 1.56 to 4.02), ischemic stroke (aHR: 1.56; 95% CI: 1.07 to 2.28), intracerebral hemorrhage (aHR: 1.67; 95% CI: 1.01 to 2.76), acute kidney injury (aHR: 1.44; 95% CI: 1.27 to 1.63), blood transfusion (aHR: 1.28; 95% CI: 1.09 to 1.50), staphylococcal (aHR: 1.71; 95% CI: 1.49 to 1.97), and fungal endocarditis (aHR: 1.72; 95% CI: 1.23 to 2.39) (p < 0.05 for all) portended higher mortality following endocarditis.ConclusionsThe incidence of endocarditis after TAVR is low and declining. However, it is associated with poor prognosis with one-half the patients dying within 1 year.
