Frequency, characteristics, and outcomes of endovascular thrombectomy in patients with stroke beyond 6 hours of onset in US clinical practice.
In 2018, 2 randomized controlled trials showed the benefit of endovascular thrombectomy (EVT) in acute ischemic stroke patients treated 6 to 24 hours from last known well using imaging-guided selection. However, little is known about outcomes in contemporary nontrial settings. In this study, the investigators assessed the frequency of EVT and outcomes beyond 6 hours in the US Get With The Guidelines-Stroke clinical registry.

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.

Transradial access for high-risk percutaneous coronary intervention: implications of the risk-treatment paradox.
The study’s objective was to examine whether the association between transradial percutaneous coronary intervention (PCI; TRI) use versus transfemoral PCI (TFI) and in-hospital outcomes is influenced by baseline risk. TRI was found to reduce adverse outcomes when compared with TFI. The authors analyzed 28,005 PCIs performed in a 7-hospital system between July 2009 and April 2018. TRI use increased over time. However a risk-treatment paradox for TRI use was observed not only for bleeding risk, but for acute kidney injury (AKI) and death. The absolute risk difference between TRI and TFI increased with increasing baseline risk.

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.

Improving smoking and blood pressure outcomes: the interplay between operational changes and local context.
This study identified conditions and operational changes linked to improvements in smoking and blood pressure (BP) outcomes in primary care using samples and interviews from a subset of 104 practices participating in EvidenceNOW, a multisite cardiovascular disease prevention initiative. The authors calculated Clinical Quality Measure improvements, with targets of 10-point or greater absolute improvements in the proportion of patients with smoking screening, and if relevant, counseling and the proportion of hypertensive patients with adequately controlled BP. Primary care staff were surveyed and interviewed. In clinician-owned practices, implementing a workflow to routinely screen and counsel patients on smoking cessation resources, or implementing a documentation change or a referral to a resource alone led to an improvement of at least 10 points in the smoking outcome. These improvements did not occur though in health- or hospital system-owned practices or in Federally Qualified Health Centers. BP outcome improved by at least 10 points among solo practices after medical assistants learned how to take an accurate BP. Among larger, clinician-owned practices, BP outcomes improvement took place when staff took a second BP measurement after the first measurement was elevated and when staff learned where to document this information in the electronic health record. For larger and health- and hospital system-owned practices, 50 or more hours of facilitation was needed to improve BP outcomes.

Effect of concomitant deep venous reflux on truncal endovenous ablation outcomes in the Vascular Quality Initiative.
This study looked at outcomes for patients with varicose veins (C2 disease) undergoing truncal endovenous ablation with and without deep venous reflux. Data from the Vascular Quality Initiative was analyzed from 2015 to 2019. A total of 4881 patients were included, with 46.2% having combined deep and superficial reflux. Follow-up around a year later (median 336.5 days) was conducted after. Patients with deep reflux were less likely to be female, more likely to be Caucasian, and had no difference in BMI. Additionally, there were no differences in rates of prior varicose vein treatments, number of pregnancies, or history of deep venous thrombosis. However, patients without deep reflux were more likely to use anticoagulants at the time of the procedure. Patients without deep reflux had slightly higher median preprocedural Venous Clinician Severity Score (VCSS) scores as well as postprocedural VCSS scores. Total symptom score was higher for patients without deep reflux before and after the procedure, but there was no change in symptom score after the procedure. Patients with deep reflux had substantially higher rates of complications with a particular increase in proximal thrombus extension.

Outcomes after truncal ablation with or without concomitant phlebectomy for isolated symptomatic varicose veins (C2 disease).
This study looked outcomes of patients with varicose veins (C2 disease) who were treated with venous ablation alone or ablation plus phlebectomy using the Vascular Quality Initiative Varicose Vein Registry. Data between January 2015 and March 2015 was used to investigate postoperative as well as long-term clinical and patient-reported outcomes among patients with documented symptomatic C2 disease undergoing truncal endovenous ablations alone and combined ablation and phlebectomy. Out of 3375 patients, 40.1% underwent isolated truncal ablation and the rest had the combined procedure of ablation and phlebectomy. Complications were low for both procedures (8.4% and 8.7%). Overall, improvement in symptoms was experienced by 94.4% of patients with more increases in patients undergoing ablation and phlebectomy than ablation alone. Both procedures are recommended by the authors to be covered by insurance.

Gender-based differences in outcomes among resuscitated patients with out-of-hospital cardiac arrest.
In this study, the investigators examined gender based differences in outcomes among resuscitated patients with out-of-hospital cardiac arrest. Studies examining gender-based differences in outcomes of out-of-hospital cardiac arrest patients have demonstrated that despite a higher likelihood of return of spontaneous circulation, women do not have higher survival. The investigators concluded that among resuscitated out-of-hospital cardiac arrest patients, discharge to survival was significantly lower in women compared with men especially among patients considered to have a favorable prognosis.

Determinants of hospital variation in cardiac rehabilitation enrollment during coronary artery disease episodes of care.
Cardiac rehabilitation (CR) is associated with improved outcomes for patients with coronary artery disease (CAD). However, CR enrollment remains low and there is a dearth of real-world data on hospital-level variation in CR enrollment. In this study, the investigators sought to explore determinants of hospital variability in CR enrollment during CAD episodes of care: medical management of acute myocardial infarction (AMI-MM), percutaneous coronary intervention (PCI), and coronary artery bypass grafting (CABG).

Risk of kidney failure, death, and cardiovascular events after lower limb complications in patients with CKD.
Investigators sought to determine how interim lower limb complications modify the subsequent risk of progression to kidney failure, all-cause mortality before kidney failure, and cardiovascular events in a cohort of patients with chronic kidney disease (CKD) stages G3 to G5. Patient-level data obtained from several administrative databases from Manitoba, Canada, were analyzed. They found that interim lower limb complications were associated with an increased risk of kidney failure, all-cause mortality before kidney failure, and cardiovascular-related hospitalization. They stated that clinical trials of screening and treatment strategies for patients with CKD at risk for lower limb complications may help determine optimal strategies to manage this risk.

The cost of implementing and sustaining the COMprehensive Post-Acute Stroke Services model.
This study compares the outcomes of using the COMprehensive Post-Acute Stroke Services (COMPASS) model, a transitional care intervention for stroke patients discharged to home against status quo postacute stroke care in a cluster-randomized trial in 40 hospitals in North Carolina. Hospital-level costs associated with implementing and sustaining COMPASS were examined during a 1-year period. Out of 40 hospitals, 22 hospitals were actively engaged in COMPASS. A 10% higher stroke patient volume was associated with 5.1% lower COMPASS costs per patient. About half of hospitals (N = 10) reported postacute clinic visits as their highest cost activity, while 7 hospitals reported case ascertainment as their highest cost activity. The authors estimated that based on average costs of COMPASS and readmissions, COMPASS could lower net costs if the model can prevent about 6 readmissions per year.

Early diagnosis and treatment of intracerebral hemorrhage (ICH) is thought to be critical for improving outcomes. In this study the investigators examined whether racial or ethnic disparities existed in acute care processes in the first hours after ICH. The investigators found no evidence of racial/ethnic disparities in acute care processes or outcomes in ICH. English as first language, however, was associated with slower care processes.

Comparison of unilateral vs bilateral and staged bilateral vs concurrent bilateral truncal endovenous ablation in the Vascular Quality Initiative.
This study compares outcomes in patients who have undergone unilateral vs bilateral venous ablation procedures or between staged and concurrent bilateral procedures. Data from the Vascular Quality Initiative from 2015 to 2019 was used to investigate immediate postoperative as well as long-term clinical and patient-reported outcomes. A total of 5029 patients were included, of whom 75.2% underwent unilateral procedures. Follow-up was conducted with a median of 227 days after. Unilateral patients were less likely to be female and white and had lower BMI compared with patients undergoing bilateral procedures. In addition, unilateral patients had fewer prior varicose vein treatments and had higher Venous Clinical Severity Scores (VCSS). There were no differences in complications in patients undergoing unilateral vs bilateral procedures. Systemic complications were rare in both groups.

Complex relationship between low albumin level and poor outcome after lower extremity procedures for peripheral artery disease.
Researchers sought to examine the association of low albumin level with outcomes in patients undergoing open and endovascular lower extremity procedures for peripheral artery disease. Subjects were patients with peripheral artery disease undergoing lower extremity procedures, selected from Cerner Health Facts database using ICD-9 diagnosis and procedure codes. They found that low preoperative albumin levels were associated with in-hospital death, prolonged length of stay, and severe morbidity after open and endovascular lower extremity procedures. They recommended that elective procedures be deferred until albumin levels have been optimized.

Should we implement geographic or patient-reported social determinants of health measures in cardiovascular patients.
The authors compared patient-reported social determinants of health (SDOH) to the Brokamp Area Deprivation Index (ADI) and then evaluated the association of patient-reported SDOH and ADI with mortality in patients with cardiovascular disease (CVD). They found that the Brokamp ADI is associated with mortality in hospitalized patients with CVD. They recommended that, in the absence of available patient-reported data, hospitals implement the Brokamp ADI as an approximation for patient-reported data to enhance risk stratification of patients with CVD.
