    Kurzfassung: The National Cardiovascular Data Registry CathPCI Registry was recently linked with longitudinal Centers for Medicare & Medicaid (CMS) claims data. The degree to which this linked cohort is representative of the overall CathPCI Registry and CMS PCI populations is unknown. Methods and Results— CathPCI Registry records were linked to CMS inpatient claims using indirect identifiers. We examined the degree to which hospitals and patients in the linked cohort are representative of the elderly (≥65 years) CathPCI Registry and CMS populations. From 2004 to 2006, 1492 hospitals filed CMS PCI claims and 663 contributed CathPCI Registry data. Of these hospitals, 643 (97%) were linked across data sources. Compared with all CMS PCI hospitals, the linked data set contained fewer governmental, northeastern, southern, and low-volume ( 〈 200 beds) sites. Among CMS beneficiaries, 993 351 PCI procedures were performed, including 398 508 (40.1%) at centers in the linked database. Of these, 341 916 (86%) were linked to CathPCI Registry records. Linked and unlinked CMS patients had similar demographic and clinical features. In the CathPCI Registry database, 477 456 elderly patients underwent PCI, with 359 077 (75%) linked to CMS claims. Linked and unlinked National Cardiovascular Data Registry patients were similar, except for less commercial or health maintenance organization insurance in the linked cohort. Conclusions— By using deterministic matching strategies, a large and representative cohort with detailed clinical data from the CathPCI Registry and longitudinal follow-up from CMS claims has been created.

    Kurzfassung: Optimal antithrombotic management of patients with preexisting atrial fibrillation undergoing transcatheter aortic valve replacement is challenging given the need to balance the risk of bleeding and thromboembolism. We aimed to examine variation in care and association of antithrombotic therapies with 1-year outcomes of stroke, bleeding, and mortality in patients undergoing transcatheter aortic valve replacement with concomitant atrial fibrillation in the United States. Methods: Patients who underwent transcatheter aortic valve replacement with preexisting atrial fibrillation from November 2011 through September 2015 in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy registry linked to the Medicare database were examined according to receipt of oral anticoagulants (OACs) or antiplatelet therapies (APTs) or a combination of these (OAC+APT) at discharge. To assess the associations of antithrombotic therapies with 1-year outcomes of stroke, bleeding, and mortality, we utilized inverse probability weighting for antithrombotic therapies and multivariable regression modeling to adjust for patient- and hospital-level variables. Results: In the 11 382 patients included in our study, 5833 (51.2%) were discharged on OAC+APT, 4786 (42.0%) on APT alone, and 763 (6.7%) on OAC alone. There was significant variability in discharge medication patterns, including 42% of patients discharged without OAC therapy. In adjusted analyses, the risk for all-cause mortality and stroke was not significantly different when comparing the 3 different antithrombotic strategies. Risk of bleeding was higher with OAC+APT compared with APT alone (hazard ratio, 1.16 [95% CI, 1.05–1.27]) and similar compared with OAC alone (hazard ratio, 1.17 [95% CI, 0.93–1.47] ). Conclusions: There was significant variability in discharge medication patterns across US sites in patients with atrial fibrillation undergoing transcatheter aortic valve replacement, including significant underuse of OAC in this high-risk cohort. The use of OAC+APT (versus OAC alone or APT alone) was not associated with a lower risk of stroke or mortality but was associated with increased risk of bleeding complications at 1 year compared with APT alone.

    Kurzfassung: The use of transcatheter aortic valve replacement (TAVR) to treat aortic stenosis in the United States is growing, yet little is known about the variation in procedural outcomes in community practice. We developed a TAVR in-hospital mortality risk model and used it to quantify variation in mortality rates across United States (US) TAVR centers. Methods and Results— We analyzed data from 22 248 TAVR procedures performed at 318 sites participating in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry (November 2011 to October 2014). A Bayesian hierarchical model was developed to estimate hospital-specific risk-adjusted mortality rates adjusting for 40 patient baseline factors. A total of 1130 in-hospital deaths (5.1%) were observed. Reliability-adjusted risk-adjusted mortality rate estimates ranged from 3.4% to 7.7% with an interquartile range of 4.8% to 5.4%. A patient’s predicted odds of dying was 80% higher if treated by a hospital 1 standard deviation above the mean compared with a hospital 1 standard deviation below the mean (odds ratio =1.8; 95% credible interval, 1.4%–2.2%). Conclusions— Risk modeling of TAVR in-hospital mortality revealed variation in risk-adjusted mortality rates during the US early commercial experience. Transcatheter Valve Therapy Registry analyses using this model will support research, feedback reporting, and the identification of factors associated with quality.

    Kurzfassung: Background— Temporal trends and contemporary data characterizing the impact of patient age on in-hospital outcomes of percutaneous coronary interventions are lacking. We sought to determine the importance of age by assessing the in-hospital mortality of stratified age groups in the National Cardiovascular Data Registry. Methods and Results— In-hospital mortality after percutaneous coronary intervention on 1 410 069 patients was age stratified into 4 groups—group 1 (age 〈 40, n=25 679), group 2 (40 to 59, n=496 204), group 3 (60 to 79, n=732 574), and group 4 (≥80, n=155 612)—admitted from January 1, 2001, to December 31, 2006. Overall in-hospital mortality was 1.22%; in-hospital mortality was 0.60%, 0.59%, 1.26%, and 3.16% in groups 1 to 4, respectively, P 〈 0.0001. Overall temporal improvement per calendar year in the adjusted in-hospital mortality after percutaneous coronary intervention was noted in most groups; however, this finding was significant only in the 2 older age groups, group 3 (odds ratio, 0.94; 95% CI, 0.92 to 0.96) and group 4 (odds ratio, 0.95; 95% CI, 0.92 to 0.97). The absolute mortality reduction was greatest in the most elderly group, those over the age of 80 years. Conclusions— In-hospital mortality after percutaneous coronary intervention has fallen for all age groups over the past 6 years. However, the largest absolute reduction was seen among patients 80 years of age or older.

    Kurzfassung: Efforts to improve quality of care for patients with acute myocardial infarction (AMI) are a national priority. To date, there have been few studies that have prospectively evaluated hospital quality improvement (QI) interventions. Methods and Results— Using hospitals in the National Cardiovascular Data Registry (NCDR) ACTION Registry–GWTG, a cluster randomized trial of the effectiveness of targeted performance feedback to facilitate process improvement for AMI care will be conducted. ACTION Registry–GWTG hospitals with a minimum of 50 AMI patients per 2 quarters are eligible for randomization. The control arm receives standard performance feedback reports, and the intervention arm receives standard performance feedback reports in addition to a supplemental report on the “top 3” centrally identified, hospital-specific performance gaps. The primary outcome will be improvement in a composite of all metrics, and the secondary outcome will be improvement in the targeted metrics. At study inception in January 2009, 149 sites were randomized: 76 to the intervention arm, and 73 to the control arm. Intervention and control sites were well balanced in terms of baseline performance, center characteristics, and AMI volume (≈70 patients per quarter). The intervention phase will continue for 5 feedback cycles, each containing 2 quarters of data feedback over 18 months. A final trial outcome report will follow. Conclusions— This randomized trial will evaluate a novel hospital-level QI intervention of targeted performance feedback for AMI, thereby demonstrating the effective use of national registries for QI and furthering our understanding of effective QI methods.

    Kurzfassung: Background— Since the broad dissemination of practice guidelines, the association of specialty care with the treatment of patients with acute coronary syndromes has not been studied. Methods and Results— We evaluated 55 994 patients with non–ST-segment elevation acute coronary syndromes (ischemic ST-segment changes and/or positive cardiac markers) included in the CRUSADE (Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the ACC/AHA Guidelines) Quality Improvement Initiative from January 2001 through September 2003 at 301 tertiary US hospitals with full revascularization capabilities. We compared baseline characteristics, the use of American College of Cardiology/American Heart Association guidelines class I recommendations, and in-hospital outcomes by the specialty of the primary in-patient service (cardiology versus noncardiology). A total of 35 374 patients (63.2%) were primarily cared for by a cardiology service, and these patients had lower-risk clinical characteristics, but they more commonly received acute (≤24 hours) medications, invasive cardiac procedures, and discharge medications and lifestyle interventions. Acute care processes were improved when care was provided by a cardiology service regardless of the propensity to receive cardiology care. The adjusted risk of in-hospital mortality was lower with care provided by a cardiology service (adjusted odds ratio 0.80, 95% confidence interval 0.73 to 0.88), and adjustment for differences in the use of acute medications and invasive procedures partially attenuated this mortality difference (adjusted odds ratio 0.92, 95% confidence interval 0.83 to 1.02). Conclusions— Non–ST-segment elevation acute coronary syndrome patients primarily cared for by a cardiology inpatient service more commonly received evidence-based treatments and had a lower risk of mortality, but these patients had lower-risk clinical characteristics. Results from the present analysis highlight the difficulties with accurately determining how specialty care is associated with treatment patterns and clinical outcomes for patients with acute coronary syndromes. Novel methodologies for evaluating the influence of specialty care for these patients need to be developed and applied to future studies.

    Kurzfassung: Surgical risk scores do not include frailty assessments (eg, gait speed), which are of particular importance for patients with severe aortic stenosis considering transcatheter aortic valve replacement. Methods and Results— We assessed the association of 5-m gait speed with outcomes in a cohort of 8039 patients who underwent transcatheter aortic valve replacement (November 2011–June 2014) and were included in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry. We evaluated the association between continuous and categorical gait speed and 30-day all-cause mortality before and after adjustment for Society of Thoracic Surgeons–predicted risk of mortality score and key variables. Secondary outcomes included in-hospital mortality, bleeding, acute kidney injury, and stroke. The overall median gait speed was 0.63 m/s (25th–75th percentile, 0.47–0.79 m/s), with the slowest walkers ( 〈 0.5 m/s) constituting 28%, slow walkers (0.5–0.83 m/s) making up 48%, and normal walkers ( 〉 0.83 m/s) constituting 24% of the population. Thirty-day all-cause mortality rates were 8.4%, 6.6%, and 5.4% for the slowest, slow, and normal walkers, respectively ( P 〈 0.001). Each 0.2-m/s decrease in gait speed corresponded to an 11% increase in 30-day mortality (adjusted odds ratio, 1.11; 95% confidence interval, 1.01–1.22). The slowest walkers had 35% higher 30-day mortality than normal walkers (adjusted odds ratio, 1.35; 95% confidence interval, 1.01–1.80), significantly longer hospital stays, and a lower probability of being discharged to home. Conclusions— Gait speed is independently associated with 30-day mortality after transcatheter aortic valve replacement. Identification of frail patients with the slowest gait speeds facilitates preprocedural evaluation and anticipation of a higher level of postprocedural care.

    Kurzfassung: Background— There is a recognized need for a national unified registry to track presenting features, care, and outcomes for patients with acute myocardial infarction. To address this need, the American Heart Association’s Get With the Guidelines–Coronary Artery Disease program joined the Acute Coronary Treatment and Intervention Outcomes Network (ACTION) Registry to create the National Cardiovascular Data Registry ACTION–Get With the Guidelines (AR-G) in June of 2008. This article outlines the objectives, operational structure, patient population, data elements, data collection methodology, and reporting components of this landmark registry. Methods and Results— The AR-G was launched in January of 2007. The registry is led by a team of volunteers from the American Heart Association and the American College of Cardiology, and its data coordinating center resides at the Duke Clinical Research Institute. As of December 2008, 344 US hospitals already contributed detailed clinical information on 103 890 myocardial infarction patients (inclusive of 39% ST-segment myocardial infarction and 61% non–ST-segment myocardial infarction patients). Overall data quality has been excellent, with 〈 5% clinical fields missing. Site quality improvement efforts are supported via detailed quarterly feedback reports, routine web educational programs, and sharing of “best practice” clinical support tools. Conclusions— The AR-G represents a unified, national, acute myocardial infarction registry and supports a robust quality improvement effort designed to encourage evidence-based acute myocardial infarction care and, ultimately, improve patient outcomes.
