Interhospital failure to rescue after coronary artery bypass grafting.
Researchers conducted an observational study to evaluate whether interhospital variation in mortality rates for coronary artery bypass grafting was driven by complications and failure to rescue. Subjects were patients undergoing grafting surgery across 90 hospitals between 2011 and 2017. Results indicated the predicted mortality risk was similar across hospital observed:expected mortality terciles. Observed and expected failure to rescue rates were positively correlated among patients with major and overall complications. The researchers concluded that interhospital variability in successful rescue after coronary artery bypass grafting supports the importance of identifying best practices at high-performing hospitals; this includes early recognition and management of complications.

Aortic visceral segment instability is evident following thoracic endovascular aortic repair for acute and subacute type B aortic dissection.
The purpose of this multicenter retrospective study was to investigate the visceral aortic behavior after thoracic endovascular aortic repair (TEVAR) for acute or subacute type B aortic dissection (TBAD) to identify any correlations with the clinical outcomes. The researchers reviewed all imaging studies for all patients from 2006 to 2020 who had undergone TEVAR for acute (0-14 days) and subacute (14-90 days) nontraumatic TBAD, identifying a total of 82 patients. The study found that VSI was present in 55% of the cohort, with an average maximal increase in the TAD of 10.4 ± 6.3 mm during a median follow-up of 2.1 years. Approximately one third of the cohort had experienced rapid VSI (growth ≥5 mm in the first year), and 4.8% of the cohort had developed a large paravisceral aortic aneurysm (TAD ≥5 cm) secondary to VSI. The preoperative factor most strongly associated with VSI was a cumulative number of zones dissected of six or more. The odds for aortic reintervention were significantly increased for cases in which VSI led to the development of a paravisceral aortic aneurysm of greater than or equal to 5 cm. The researchers concluded that VSI was identified in most patients who had undergone TEVAR for management of acute and subacute TBAD, and also identified a subset of patients who might have an increased risk of reintervention. The study results emphasize the importance of ongoing and lifelong monitoring after TEVAR.

Determinants of hospital variability in perioperative red blood cell transfusions during coronary artery bypass graft surgery.
This observational cohort study’s objective was to identify to what extent distinguishing patient and procedural characteristics can explain center-level transfusion variation during coronary artery bypass grafting (CABG) surgery. The study used patients from the Perfusion Measures and Outcomes Registry from 43 adult cardiac surgical programs from July 2011 through June 2017. Of the 22,272 adult patients undergoing isolate CABG surgery using cardiopulmonary bypass, 7241 (32.5%) received at least 1 U allogeneic red blood cells. Patients who received transfusions were older (68 vs 64 years), were women (41.5% vs 15.9%), and had a lower body surface area, respectively. The majority of center-level transfusion variations could not be explained through models containing both patient and intraoperative factors.

Non-patient factors associated with infections in LVAD recipients: a scoping review.
Infections are the most common complication in recipients of durable left ventricular assist devices (LVAD) and are associated with increased morbidity, mortality, and expenditures. The existing literature examining factors associated with infection in LVAD recipients is limited and principally comprises single-center studies. This scoping review synthesized all available evidence related to identifying modifiable, non-patient factors associated with infections among LVAD recipients.

Predictors and outcomes of heart block during surgical stage I palliation of patients with a single ventricle: a report from the NPC-QIC.
This study investigated patient and surgical risks of heart block and its effect on 12-month transplant-free survival in children with a single ventricle. In total, 1423 patients were identified from the National Pediatric Cardiology Improvement Collaborative with and without heart block. One-year outcomes were analyzed. A very small percentage (2%) developed heart block during their surgical admission. Associated risk factors for block included heterotaxy syndrome and atrial flutter/fibrillation. Patients with complete heart block had lower 12-month survival, which wasn’t true for patients with second degree block. At 12 months of age, 43% of patients with heart block died and were more likely to experience mortality than patients without heart block.

The impact of team familiarity on intra and postoperative cardiac surgical outcomes.
The authors hypothesized that familiarity among cardiac surgery team members may be an important contributor to better outcomes and thus serve as a target for enhancing outcomes. They found that high team familiarity was associated with reduced cardiopulmonary bypass duration for medium-risk and high-risk patients. Increasing team familiarity was not significantly associated with the odds of major morbidity and mortality. They concluded that team familiarity, which was predictive of improved intraoperative efficiency without compromising major postoperative outcomes, may serve as a novel quality improvement target in the setting of cardiac surgery.

Coronary revascularization outcomes in relation to skilled nursing facility use following hospital discharge.
Observational analyses comparing coronary artery bypass surgery (CABG) and percutaneous coronary intervention (PCI) among elderly or frail patients are likely biased by treatment selection. PCI is typically chosen for frail patients, while CABG is more common for patients with good recovery potential. In this study. The investigators hypothesized that skilled nursing facility (SNF) use after revascularization was a measure of relative frailty associated with outcomes following coronary revascularization.

Provider care team segregation and operative mortality following coronary artery bypass grafting.
The purpose of this study was to examine whether provider care team segregation within hospitals contributes to the higher mortality rate of Black patients following coronary artery bypass grafting compared to their White counterparts. Using national Medicare data, findings showed that Black patients who undergo coronary artery bypass grafting at a hospital with a higher level of provider care team segregation die more frequently after surgery than Black patients treated at a hospital with a lower level.

Designing a patient-specific search of transplant program performance and outcomes: feedback from heart transplant candidates and recipients.
The Scientific Registry of Transplant Recipients provides transplant program-specific information, but it is unclear what patients and stakeholders need to know. Acceptance criteria for the candidate waitlist and donor organs vary by program and region, but there is no means to search for programs by the clinical profiles of recipients and donors. The authors examined variability in program-specific characteristics that could influence access to transplantation.

Long-term trends in preoperative cardiac evaluation and myocardial infarction after elective vascular procedures.
This retrospective cohort study was performed using data on elective vascular surgery procedures and evaluated long-term trends in post-operative myocardial infarction (POMI) using Vascular Surgery Vascular Quality Initiative (VQI) registry data for patients undergoing carotid endarterectomy (CEA), thoracic endovascular aortic repair (TEVAR), endovascular aortic repair (EVAR), open abdominal aortic aneurysm repair (oAAA), suprainguinal bypass (SIB), and infrainguinal bypass (IIB). A total of 227,837 elective procedures were identified. The overall rate of POMI was 1.3% across all procedures. POMI rates from 2003-05 to 2015-17 for CEA decreased from 0.9% to 0.7%, EVAR from 2% to 7%, IIB from 3.8% to 2.4%, and oAAA from 6.8% to 5.1%. From 2009 to 2017 SIB decreased from 3.06% to 2.95%. However, TEVAR increased from 2.4% to 3.56% for the period 2006 to 2017. CEA, EVAR, IIB, oAAA all showed a significant increase in postoperative statin use.

Trends, perioperative adverse events, and survival of patients with left ventricular assist devices undergoing noncardiac surgery.
This longitudinal cohort study examined outcomes of noncardiac surgery (NCS) in patients with left ventricular assist devices (LVADs). This study examined patients enrolled in Medicare who had undergone durable LVAD implantation from January 2012 to November 2017 with follow-up through December 2017. Primary outcome after NCS was major adverse cardiovascular events (MACEs), defined as in-hospital or 30-day all-cause mortality, ischemic stroke, or intracerebral hemorrhage. Of the 8118 patients with LVAD, 1326 underwent NCS with 75.4% emergent or urgent, and 24.6% elective. Both elective and urgent or emergent NCS was associated with higher mortality early and late compared with patients with LVAD who did not undergo NCS.

The effects of market competition on cardiologists' adoption of transcatheter aortic valve replacement.
This study examined the effects of market competition and unique regulations on cardiologists’ adoption of transcatheter aortic valve replacement (TAVR). This new technology was introduced around 2012. This retrospective cohort study looked at physician group practices (n=5116) from May 2012 through December 2014. Medicare claim data was used to indicate first usage. The Herfindahl-Hirschman Index was used to show that every 1000 point increase was associated with a 26% relative increase in the rate of TAVR adoption. This was most true in concentrated markets, and adoption of TAVR was favored by physician groups with greater market power.

Relationship of ventricular morphology and atrioventricular valve function to long-term outcomes following fontan procedures.
This study hypothesized that dysfunction of the single right ventricle (RV) and right atrioventricular valve regurgitation (AVVR) increases over time and adversely impacts late outcomes following a Fontan operation. Through a single-center retrospective study, findings showed that morphologic RV is negatively associated with the long-term survival following the Fontan, possibly due to a tendency toward progressive AVVR and deterioration of the single ventricle function. Additional volume overload caused by AVVR may be one of the main factors accelerating the dysfunction of the single RV, implying that early valve intervention may be warranted.

Attribution of adverse events following coronary stent placement identified using administrative claims data.
This study outlines the process used to identify adverse events following coronary stent placement identified with administrative claims data. Deterministic matching was used to link the National Cardiovascular Data Registry (NCDR) CathPCI Registry to Medicare fee-for-service claims for patients aged 65 and older who underwent percutaneous coronary interventions (PCIs) with drug-eluting stents (DESs) between July 2009 and December 2013. Out of 415,306 DES placements in 368,194 patients, 278 (1.1%) were attributed to the same coronary artery in which the DES was implanted during the index PCI. The authors concluded that more in-depth examination will be needed to accurately assess stent safety using claims data alone.

Understanding and addressing variation in health care-associated infections after durable ventricular assist device therapy: protocol for a mixed methods study.
This paper discusses an ongoing AHRQ-funded study to understand and address variation in health care-associated infections (HAIs) after durable ventricular assist device (VAD) implantation surgery. This procedure is used only on patients with advanced heart failure who have a poor 1-year estimated survival rate. This is a sequential mixed methods study which is conducting a systematic review of HAI prevention studies, and an in-depth quantitative analyses using administration claims, in-depth clinical data, and organizational surveys of VAD centers. The last aim is to develop and disseminate a best practices toolkit for HAI prevention. Data analysis is currently underway.

Association of cardiac rehabilitation with decreased hospitalization and mortality risk after cardiac valve surgery.
Investigators sought to characterize cardiac rehabilitation (CR) enrollment after cardiac valve surgery and its association with outcomes, including hospitalizations and mortality. Subjects were all fee-for-service Medicare beneficiaries undergoing open cardiac valve surgery in 2014, identified by inpatient diagnosis codes for open aortic, mitral, tricuspid, and pulmonary valve surgery. They found that fewer than half of Medicare beneficiaries undergoing cardiac valve surgery enrolled in CR programs, and there were marked racial/ethnic disparities among those who do. They recommend further study on barriers to CR enrollment in this population.

Trends in isolated surgical aortic valve replacement according to hospital-based transcatheter aortic valve replacement volumes.
This research analyzed trends in isolated surgical aortic valve replacement (SAVR) procedures with the advent of the transcatheter aortic valve replacement (TAVR) procedure. Hospitalizations of adults from January 2011 through December 2014 was analyzed with data from the Medicare Provider Analysis and Review database using ICD-9 Revision-Clinical Modification procedure codes. The annual value of isolated SAVR went down as TAVR volumes increased which also decreased short- and long-term mortality over the study period.

The value of claims-based nontraditional risk factors in predicting long-term mortality after MitraClip procedure.
The goals of this study were to identify nontraditional risk factors coded in administrative claims data and to evaluate their ability to improve prediction of long-term mortality in patients undergoing percutaneous mitral valve repair. Patients undergoing transcatheter mitral valve repair using MitraClip implantation were identified among Medicare fee-for-service beneficiaries; researchers used nested Cox regression models to identify claims codes predictive of long-term mortality. Four groups of variables were introduced: cardiac, noncardiac, and nontraditional risk factors, and presentation characteristics. The authors conclude that risk-prediction models, which include nontraditional risk factors as identified in claims data, can be used to predict long-term mortality risk more accurately in patients who have undergone MitraClip procedures.

Association of neutrophil-to-lymphocyte ratio with outcomes after elective abdominal aortic aneurysm repair.
This study investigated postoperative outcomes from elective abdominal aortic aneurysm surgery (AAA) repair using neutrophil-to-lymphocyte ratio as the predictor. Inpatients from the Cerner Health Facts database undergoing elective AAA repair from 2008 to 2015 were selected using ICD-9 procedure codes. Patients with a high postoperative NLR experienced longer hospital stays; higher rates of in-hospital death; high rates of renal failure, cardiac problems, respiratory problems, and infection compared to patients with a low postoperative NLR. The authors recommend future study of NLR to help provide clinically important risk profiles.

Feeding methods for infants with single ventricle physiology are associated with length of stay during stage 2 surgery hospitalization.
The purpose of this paper was to identify types of feeding methods following stage 2 palliation and their influence on length of stay. Results showed that feeding methods established at admission for stage 2 palliation are not likely to change by discharge, and that length of stay is more likely to be impacted by tube feeding and intubation history than by age or weight-for-age z score at admission. Recommendations included a better understanding for selection of feeding methods and their impact on patient outcomes in order to develop evidence-based guidelines to decrease variability in clinical practice patterns and to provide appropriate counseling to caregivers.

Public reporting of cardiac outcomes for patients with acute myocardial infarction: a systematic review of the evidence.
A systematic review was conducted to evaluate the effect of public reporting for patients with acute myocardial infarction (AMI), specifically for those patients who receive percutaneous coronary intervention (PCI). The investigators concluded that although public reporting may have had intentions of improving care, there was strong evidence that this policy did not result in more timely PCIs or improved mortality of patients with AMI. In fact, public reporting resulted in unintended consequences of not providing care for the most vulnerable patients in fear of an adverse outcome.

The association of preoperative cardiac stress testing with 30-day death and myocardial infarction among patients undergoing kidney transplantation.
This study examined whether the use of preoperative cardiac stress testing of patients undergoing kidney transplantation reduced 30-day- death and myocardial infarction post-transplantation. ESRD patients 40 years or older with primary Medicare insurance between 2006 and 2013 were identified using the United States Renal Data System. In a matched cohort of 17,304 patients, there was little difference in 30-day post-transplantation mortality and myocardial infarction between those receiving a stress test and those who did not.
