Is more better? The impact of implementing more interventions for hypertension control in a practice facilitation study for small- and medium-sized practices.
The purpose of this study was to research the effects of interventions for blood pressure in small- and medium-sized practices. The researchers utilized retrospective analysis on data from Healthy Hearts in the Heartland (H3), a research program conducted in 2016-2018 as part of the Agency for Healthcare Research and Quality's EvidenceNOW initiative, to examine the impact of implementing more interventions for BP control in these settings. The study included 38 H3 practices which met inclusion criteria and researchers assigned each practice to an implementer group (high or low) based on the number of interventions implemented. Practices in the high-implementer group implemented an average of 2.2 additional interventions relative to the low-implementer group. Groups were compared on two measures of BP control: (1) mean percentage of hypertensive patients with a most recent BP below 140/90, and (2) mean systolic and diastolic BP of hypertensive patients. In the first measure, practices in the high-implementer group had better improvement between baseline and the end of the study. Among the 10,150 patients included in the second measure, reductions in mean SBP and DBP were better for the high-implementer group.

Rationale and design for Healthy Hearts for Michigan (HH4M): a pragmatic single-arm hybrid effectiveness-implementation study.
The objective of the Healthy Hearts for Michigan (HH4M) study is to promote hypertension management and smoking cessation through practice facilitation and quality improvement efforts. This three-year research program evaluates rural and medically underserved primary care practices’ ability to implement the quality improvement model and tests whether the model improves blood pressure control and tobacco use screening and cessation. Primary care practices in rural and underserved areas of Michigan were recruited to join HH4M. HH4M is part of the multi-state EvidenceNOW: Building State Capacity initiative to provide external support to primary care practices to improve care delivery.

Estimating the cardiovascular disease risk reduction of a quality improvement initiative in primary care: findings from EvidenceNOW.
The purpose of this study was to estimate decreases in 10-year atherosclerotic cardiovascular disease (ASCVD) risk associated with EvidenceNOW, an initiative spanning multiple states that sought to improve cardiovascular preventive care by providing supportive interventions such as practice facilitation to address the “ABCS”: (A)spirin for high-risk patients, (B)lood pressure control for hypertensive people, (C)holesterol management, and (S)moking screening and cessation counseling. The researchers conducted an analytic modeling study that combined 1) data from 1,278 EvidenceNOW practices collected from 2015 to 2017; (2) patient-level information of 1,295 individuals who participated in the 2015 to 2016 National Health and Nutrition Examination Survey; and (3) 10-year ASCVD risk prediction equations. The study found the average 10-year ASCVD risk of these patients before intervention was 10.11%. Improvements in ABCS due to EvidenceNOW reduced their 10-year ASCVD risk to 10.03% which would prevent 3,169 ASCVD events over 10 years and $150 million in 90-day direct medical costs.

Evaluating the implementation of patient-reported outcomes in heart failure clinic: a qualitative assessment.
This study evaluated clinician perceptions of the Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12), a patient reported outcome (PRO) survey that captures symptom frequency, symptom burden, physical limitations, social limitations, and quality of life. The authors conducted interviews with cardiologists from 4 institutions across the United States and Canada (n=16) and observed clinic visits at 1 institution in Northern California (n=5). They conducted 2 rounds of interviews and did a qualitative analysis on (1) rapid analysis constructed around major themes related to the aims of the study and (2) content analysis with codes derived from the rapid analysis and implementation science. Most cardiologists reported the KCCQ-12 was acceptable, appropriate, and useful in clinical care. The survey was found to improve the consistency of patient history taking, focus patient-clinician conversations, collect a more accurate account of patient quality of life, track trends in patient well-being over time, and refine clinical decision-making.

The effect of supraceliac versus infraceliac landing zone on outcomes following fenestrated endovascular repair of juxta-/pararenal aortic aneurysms.
The purpose of this study was to assess perioperative outcomes in patients in the Vascular Quality Initiative who underwent juxta-/pararenal FEVAR with supraceliac vs infraceliac sealing. 1,486 Patients who received an elective FEVAR for juxta-/pararenal aortic aneurysms in the Vascular Quality Initiative between 2014 and 2021were identified and included.
The researchers defined supraceliac sealing as proximal sealing in aortic zone 5, or zone 6 with a celiac scallop/fenestration/branch or celiac occlusion. The study’s primary outcomes were perioperative and 3-year mortality, and secondary outcomes were completion endoleaks, in-hospital complications, and variables related with 3-year mortality. The study found that of the included patients, 84% underwent infraceliac sealing, and 16% underwent supraceliac sealing. Of the supraceliac patients, 60% had a celiac fenestration/branch, 31% had a celiac scallop, and 9.2% had a celiac occlusion (intentional or unintentional). Compared with infraceliac sealing, there were no differences after risk-adjusted analysis in perioperative mortality following supraceliac sealing. Supraceliac sealing was associated with lower odds of type-IA completion endoleaks, but higher odds of any complication including cardiac complications, lower extremity ischemia and acute kidney injury when compared with infraceliac sealing. The researchers concluded that supraceliac sealing was associated with lower risk of type IA endoleaks and similar mortality compared with sealing at an infraceliac level. The researchers advise that providers should be aware that supraceliac sealing was related with higher perioperative morbidity.

In-hospital outcomes after upper extremity versus transfemoral and transcarotid access for carotid stenting in the Vascular Quality Initiative.
This comparative study examined outcomes for treatment of patients at high risk of carotid endarterectomy using different approaches of carotid artery stenting (CAS). The study compared the effects of transradial or transbrachial (tr/tbCAS) versus more established transfemoral (tfCAS) or transcarotid (TCAR) CAS procedures. Patients were identified from the Quality Initiative registry from January 2016 to December 2021. Among 40,835 CAS identified patients, 962 underwent tr/tbCAS, 28,850 underwent tfCAS, and 21,033 underwent TCAR. Among matched patients who underwent tr/tbCAS versus tfCAS, there was no significant difference in the risk of stroke/death (4.1% vs 2.9), but tr/tbCAS was associated with a higher risk of death (2.4% vs 1.3). In the symptomatic subgroup, tr/tbCAS was associated with a higher risk of stroke/death (6.1% vs 3.9%) and death (3.6% vs 1.7%), but there were no differences in asymptomatic patients. After adjustment for Modified Rankin Scale in patients with preoperative stroke, there were no significant differences in stroke/death or death between groups.

Generating practice-based evidence in the use of guideline-recommended combination therapy for secondary prevention of acute myocardial infarction.
This study’s goal was to determine if variation in real-world practice of guideline-recommended combination therapy for secondary prevention of acute myocardial infarction (AMI) reflects poor quality-of-care or a balance of outcome tradeoffs among patients. Medicare fee-for-service beneficiaries hospitalized 2007-2008 for AMI were included. Treatment within 30-days post-discharge was grouped into one of eight possible combinations for the three drug classes: beta-blockers, angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers, and statins. Outcomes looked at included one-year overall survival, one-year cardiovascular-event-free survival, and 90-day adverse events. Results were found that each drug combination was observed in the final sample (N = 124,695), with 35.7% having all three, and 13.5% having none. There were both treatment benefits and harms in patients with AMIs with higher rates of guideline-recommended treatment.

The EvidenceNOW practice support initiative: the Heart of Virginia Healthcare.
The purpose of this study was for The Heart of Virginia Health care (HVH) collaborative (one of the Agency for Healthcare Research and Quality's (AHRQ) Evidence Now project’s 7 collaboratives) to test different ways to improve performance and outcomes on ABCS clinical quality measures (appropriate Aspirin use, Blood pressure control, Cholesterol control, and Smoking cessation counseling) within small primary care practices. The researchers recruited 264 eligible practices and randomized them to 3 cohorts in a stepped wedge design, with 173, utilizing 16 different EHRs, participated through the entire initiative. Trained coaches delivered the practice support curriculum to improve performance on the ABCS measures. The program included an initial kickoff meeting, 3 months of focused support, 9 months of continued support, and access to online materials and faculty. The intervention phase was shortened due to difficulty in recruiting a sufficient number of practices. The study found that the short HVH intervention had a small but statistically significant positive average effects on appropriate use of aspirin and other anti-thrombotics, small negative effects on blood pressure control, except for those practices which did not attend the kickoff, and small negative effects on smoking cessation counseling. The researchers concluded that the truncation of the intervention contributed to the lack of substantial improvements in the ABCS.

The development and initial validation of the PROMIS®+HF-27 and PROMIS+HF-10 profiles.
This paper describes the continued refinement of the PROMIS®-Plus-HF (PROMIS+HF) profile measure, including universal and HF-specific items, to develop shorter PROMIS+HF profiles intended for research and clinical use. The authors developed the PROMIS+HF-27 and PROMIS+HF-10 profiles with summary scores (0-100) for overall, physical, mental, and social health. In a cross-sectional sample (n = 600), they measured internal consistency reliability (Cronbach's alpha and Spearman-Brown), test-retest reliability (intraclass coefficient; n = 100), known-groups validity via New York Heart Association (NYHA) class, and convergent validity with Kansas City Cardiomyopathy Questionnaire (KCCQ) scores. They also evaluated responsiveness of baseline/follow-up scores in a longitudinal sample of 75 by calculating mean differences and Cohen’s d and comparing with paired t-tests. PROMIS+HF-27 scores showed good to excellent internal consistency and acceptable to good for PROMIS+HF-10 scores. Good psychometric characteristics were shown for both measures with evidence of responsiveness for overall and physical health.

Measuring implementation strategy fidelity in HealthyHearts NYC: a complex intervention using practice facilitation in primary care.
This study measured implementation strategy fidelity for the HealthyHearts NYC intervention program, an AHRQ-funded program that uses practice facilitation (PF) to improve adoption of cardiovascular disease evidence-based guidelines in primary care practices. Data from 257 practices measured fidelity using 4 categories: frequency, duration, content, and coverage. Almost all (94.2%) of practices received at least the 13 PF visits with an average 26.3 hours spent at each site by facilitators. Most practices (95.7%) completed all Task List items, and 71.2% were educated on all Chronic Care Models, with the majority (65.8%) receiving full coverage.

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.

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.

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.

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).

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.

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.

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.

A controlled trial of dissemination and implementation of a cardiovascular risk reduction strategy in small primary care practices.
Researchers assessed the effect of dissemination and implementation of an intervention consisting of practice facilitation and a risk-stratified, population management dashboard on cardiovascular risk reduction for patients at high risk in small, primary care practices. They found that a risk-stratified, population management dashboard combined with practice facilitation led to substantial reductions of 10-year atherosclerotic cardiovascular disease risk for patients at high risk. They recommended utilizing similar approaches to lead to effective dissemination and implementation of other new evidence, especially in rural and other under-resourced practices.

Hypocapnia, ischemic lesions, and outcomes after intracerebral hemorrhage.
This research evaluated the relationship between early pCO(2) changes, ischemic lesions and outcomes in patients with intracerebral hemorrhage (ICH). This observational cohort study ran from 2006 to 2019. Arterial blood gas (ABG) measurements and mechanical ventilation settings in the first 72 hours after admission were collected. ABG data was analyzed from 220 patients. Hyperventilation occurred in 52 (28%) of cases and was not associated with clinical severity. Lower initial pCO(2) was associated with greater risk of in-hospital death. MRI images from 33 patients was used to measure the risk of developing ischemic lesions with lower pCO(2). Lower pCO(2) was also associated with a higher risk, except in patients with low initial systolic blood pressure.

Exemplary practices in cardiovascular care: results on clinical quality measures from the EvidenceNOW Southwest Cooperative.
The authors identified practice characteristics associated with high performance on four cardiovascular disease cardiovascular clinical quality measures (CQMs). They found that multiple strategies - registries, prompts and protocols, patient self-management support, and patient-team partnership activities - were associated with delivering high-quality cardiovascular care over time, measured by CQMs.

Comparative effectiveness and safety of oral anticoagulants across kidney function in patients with atrial fibrillation.
Patients with atrial fibrillation and severely decreased kidney function were excluded from the pivotal non-vitamin K antagonist oral anticoagulants (NOAC) trials, thereby raising questions about comparative safety and effectiveness in patients with reduced kidney function. This study aimed to compare oral anticoagulants across the range of kidney function in patients with atrial fibrillation.

Computable phenotype implementation for a national, multicenter pragmatic clinical trial: lessons learned from ADAPTABLE.
This methods paper provides an overview of the development and implementation of a computable phenotype in ADAPTABLE (Aspirin Dosing: a Patient-Centric Trial Assessing Benefits and Long-Term Effectiveness)--a pragmatic, randomized, open-label clinical trial testing the optimal dose of aspirin for secondary prevention of atherosclerotic cardiovascular disease events. Lessons learned included the following: the accuracy and utility of a computable phenotype are dependent on the quality of the source data; local validation and modification were required based on site factors; and sustained collaboration among a diverse team of researchers is needed during development and implementation. The ADAPTABLE computable phenotype served as an efficient method to recruit patients in a multisite pragmatic clinical trial.
