Abstract The aim of the study was to evaluate the outcomes with completeness of revascularization (CR) in patients with multivessel disease (MVD) who underwent PCI using everolimus eluting stent (EES). Patients with MVD who underwent PCI using EES in New York State were chosen. Patients were categorized into CR, attempted but failed CR or incomplete revascularization (ICR). The primary outcome was death/ myocardial infarction (MI). Secondary outcomes were death/ MI/ repeat revascularization and ...

Abstract Background Operative mortality (in-hospital during the index admission or within 30 days of the procedure after discharge) is commonly used as a quality of care measure for public reporting of cardiac surgery outcomes, but the ability to accurately capture out-of-hospital deaths remains undetermined. The objective of the study is to estimate the impact of incomplete reporting of out-of-hospital deaths on hospital risk-adjusted mortality and outlier status. Methods New York State’s 2014-...

Abstract Background Despite recent guideline statements, there is still wide practice variation in the use of multiple arterial grafts (MAGs) versus single arterial grafts (SAGs) for patients with multivessel disease undergoing coronary artery bypass graft surgery. This may be related to differences in findings between observational and randomized controlled studies. Objectives This study sought to compare intermediate-term MAG and SAG outcomes with enhanced matching to reduce selection bias. Me...

Background:Risk adjustment is critical in the comparison of quality of care and health care outcomes for providers. Electronic health records (EHRs) have the potential to eliminate the need for costly and time-consuming manual data abstraction of patient outcomes and risk factors necessary for risk

Abstract Objective The purposes of this study are to compare outcomes of mitral valve repair (MV-repair) and mitral valve replacement for patients with severe mitral regurgitation with preserved ventricular function and no congestive heart failure (CHF) symptoms and to examine variations in surgeon choice of procedure and outcomes by surgeon volume. Methods In total, 2259 consecutive patients in 42 New York State hospitals with the characteristics mentioned previously who underwent mitral valve ...

Abstract Objectives The purpose of this study is to revisit cases rated as “inappropriate” in the 2012 appropriate use criteria (AUC) using the 2017 AUC. Background AUC for coronary revascularization in patients with stable ischemic heart disease (SIHD) were released in January 2017. Earlier 2012 AUC identified a relatively high percentage of New York State patients for whom percutaneous coronary intervention (PCI) was rated as “inappropriate” versus optimal medical therapy alone. Methods New Yo...

Abstract Transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) is the first area of interventional cardiology where women are treated as often as men. In this analysis of the gender specific results of randomised controlled trials (RCTs) comparing TAVI with surgical aortic valve replacement (SAVR) we aimed to determine whether gender affects the survival comparison between TAVI and SAVR. We identified all RCTs comparing TAVI versus SAVR for severe AS and reporting 1 and/...

Abstract Background Recent studies have demonstrated relatively high rates of percutaneous coronary interventions (PCIs) classified as “inappropriate.” The New York State Department of Health shared rates with hospitals and announced the intention of withholding reimbursement pending demonstration of clinical rationale for Medicaid patients with inappropriate PCIs. Objectives The objective was to examine changes over time in the number and rate of inappropriate PCIs. Methods Appropriate use crit...

Background— Guidelines recommend coronary artery bypass graft surgery (CABG) over percutaneous coronary intervention (PCI) for multivessel disease and severe left ventricular systolic dysfunction. However, CABG has not been compared with PCI in such patients in randomized trials. Methods and Results— Patients with multivessel disease and severe left ventricular systolic dysfunction (ejection fraction ≤35%) who underwent either PCI with everolimus-eluting stent or CABG were selected from the New ...

Background:Hospitals’ risk-standardized mortality rates and outlier status (significantly higher/lower rates) are reported by the Centers for Medicare and Medicaid Services (CMS) for acute myocardial infarction (AMI) patients using Medicare claims data. New York now has AMI claims data with blood pr
