Effects of an Intervention to Improve Evidence-Based Care for People With Diabetes and Cardiovascular Disease Across Sex, Race, and Ethnicity Subgroups: Insights From the COORDINATE-Diabetes Trial.

BACKGROUND: Results from the COORDINATE-Diabetes trial demonstrated that a multifaceted, clinic-based intervention increased prescription of evidence-based medical therapies to participants with type 2 diabetes and atherosclerotic cardiovascular disease. This secondary analysis assessed whether intervention success was consistent across sex, race, and ethnicity. METHODS: COORDINATE-Diabetes, a cluster randomized trial, recruited participants from 43 US cardiology clinics (20 randomized to intervention and 23 randomized to usual care). The primary outcome was the proportion of participants prescribed all 3 groups of evidence-based therapy (high-intensity statin, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, and sodium-glucose cotransporter-2 inhibitor or glucagon-like peptide 1 receptor agonist) at last trial assessment (6 to 12 months). In this prespecified analysis, mixed-effects logistic regression models were used to assess the outcome by self-reported sex, race, and ethnicity in the intervention and usual care groups, with adjustment for baseline characteristics, medications, comorbidities, and site location. RESULTS: Among 1045 participants with type 2 diabetes and atherosclerotic cardiovascular disease, the median age was 70 years, 32% were female, 16% were Black, and 9% were Hispanic. At the last trial assessment, there was an absolute increase in the proportion of participants prescribed all 3 groups of evidence-based therapy in women (36% versus 15%), Black participants (41% versus 18%), and Hispanic participants (46% versus 18%) with the intervention compared with usual care, with consistent benefit across sex (male versus female; Pinteraction=0.44), race (Black versus White; Pinteraction=0.59), and ethnicity (Hispanic versus Non-Hispanic; Pinteraction= 0.78). CONCLUSIONS: The COORDINATE-Diabetes intervention successfully improved delivery of evidence-based care, regardless of sex, race, or ethnicity. Widespread dissemination of this intervention could improve equitable health care quality, particularly among women and minority communities who are frequently underrepresented in clinical trials.

Remote Follow-up in a Heart Failure Pragmatic Trial: Insights From the CONNECT-HF.

BACKGROUND: Randomized controlled trials typically require study-specific visits, which can burden participants and sites. Remote follow-up, such as centralized call centers for participant-reported or site-reported, holds promise for reducing costs and enhancing the pragmatism of trials. In this secondary analysis of the CONNECT-HF (Care Optimization Through Patient and Hospital Engagement For HF) trial, we aimed to evaluate the completeness and validity of the remote follow-up process. METHODS AND RESULTS: The CONNECT-HF trial evaluated the effect of a post-discharge quality-improvement intervention for heart failure compared to usual care for up to 1 year. Suspected events were reported either by participants or by health care proxies through a centralized call center or by sites through medical-record queries. When potential hospitalization events were suspected, additional medical records were collected and adjudicated. Among 5942 potential hospitalizations, 18% were only participant-reported, 28% were reported by both participants and sites, and 50% were only site-reported. Concordance rates between the participant/site reports and adjudication for hospitalization were high: 87% participant-reported, 86% both, and 86% site-reported. Rates of adjudicated heart failure hospitalization events among adjudicated all-cause hospitalization were lower but also consistent: 45% participant-reported, 50% both, and 50% site-reported. CONCLUSIONS: Participant-only and site-only reports missed a substantial number of hospitalization events. We observed similar concordance between participant/site reports and adjudication for hospitalizations. Combining participant-reported and site-reported outcomes data is important to capture and validate hospitalizations effectively in pragmatic heart failure trials.

Comparing the Classification of Percutaneous Coronary Interventions Using the 2012 and 2017 Appropriate Use Criteria: Insights From 245,196 Patients in the NCDR CathPCI Registry.

BACKGROUND: Appropriate use criteria (AUC) have been developed to promote the rational use of percutaneous coronary intervention (PCI) among clinicians and to provide benchmarking feedback to hospitals. The original AUC were published in 2012 and subsequently updated in 2017 to reflect emerging, contemporary evidence however the degree to which the updated guidance re-classifies PCI appropriateness is unknown. METHODS: Elective PCI cases from March 1, 2018 until June 30, 2021 were identified from within the NCDR CathPCI database. PCI cases were classified as 'appropriate,' 'uncertain' or 'inappropriate' under 2012 AUC and 'appropriate,' 'may be appropriate' or 'rarely appropriate' under 2017 AUC; those with missing data elements were termed 'not mappable.' Groups that 'remained appropriate' (appropriate in both 2012 and 2017), 'became non-appropriate' ('appropriate' in 2012 but became either 'may be appropriate' or 'rarely appropriate in 2017) and 'became appropriate' ('appropriate' in 2017 but were 'uncertain' or 'inappropriate' in 2012) were descriptively compared. Concordance was assessed by calculation of Cohen's Kappa. RESULTS: A total of 245,196 patients underwent elective PCI across 1669 centers. By 2012 AUC, 44% were classified 'appropriate,' 28% were 'uncertain' and 16% were 'inappropriate' compared with 2017 AUC which considered 34% 'appropriate', 56% may be 'appropriate' and 4% 'rarely appropriate'. Overall fair agreement was observed with a Kappa statistic of 0.40 (95%CI 0.396-0.403). Compared with PCI that 'remained appropriate' under the 2017 AUC, PCI that 'became non-appropriate' in 2017 were more likely to be asymptomatic, less likely to be on anti-anginals and less likely to have complex lesions. Compared with PCI that 'became non-appropriate', PCI that 'became appropriate' had a higher proportion of atypical and non-anginal symptoms and were less likely to have had positive functional tests. Procedural related outcomes were similar across all groups. A total of 29 429 PCI (12.0%) were not mappable by 2012 AUC while 16 077 (6.6%) were not mappable by 2017 AUC. CONCLUSIONS: In this contemporary analysis of patients undergoing PCI in the United States, only fair agreement between the 2012 and updated 2017 AUC was observed. While some of this reflects the intention of the updated guidance, the large proportion that were considered 'maybe appropriate' or who 'became non-appropriate' reflect the difficulties of documenting and implementing contemporary AUC guidance.

Coordinating Cardiology clinics randomized trial of interventions to improve outcomes (COORDINATE) - Diabetes: rationale and design.

Several medications that are proven to reduce cardiovascular events exist for individuals with type 2 diabetes mellitus (T2DM) and atherosclerotic cardiovascular disease, however they are substantially underused in clinical practice. Clinician, patient, and system-level barriers all contribute to these gaps in care; yet, there is a paucity of high quality, rigorous studies evaluating the role of interventions to increase utilization. The COORDINATE-Diabetes trial randomized 42 cardiology clinics across the United States to either a multifaceted, site-specific intervention focused on evidence-based care for patients with T2DM or standard of care. The multifaceted intervention comprised the development of an interdisciplinary care pathway for each clinic, audit-and-feedback tools and educational outreach, in addition to patient-facing tools. The primary outcome is the proportion of individuals with T2DM prescribed three key classes of evidence-based medications (high-intensity statin, angiotensin converting enzyme inhibitor or angiotensin receptor blocker, and either a sodium/glucose cotransporter-2 inhibitor (SGLT-2i) inhibitor or glucagon-like peptide 1 receptor agonist (GLP-1RA) and will be assessed at least 6 months after participant enrollment. COORDINATE-Diabetes aims to identify strategies that improve the implementation and adoption of evidence-based therapies.

Coordinated Care to Optimize Cardiovascular Preventive Therapies in Type 2 Diabetes: A Randomized Clinical Trial.

Importance: Evidence-based therapies to reduce atherosclerotic cardiovascular disease risk in adults with type 2 diabetes are underused in clinical practice. Objective: To assess the effect of a coordinated, multifaceted intervention of assessment, education, and feedback vs usual care on the proportion of adults with type 2 diabetes and atherosclerotic cardiovascular disease prescribed all 3 groups of recommended, evidence-based therapies (high-intensity statins, angiotensin-converting enzyme inhibitors [ACEIs] or angiotensin receptor blockers [ARBs], and sodium-glucose cotransporter 2 [SGLT2] inhibitors and/or glucagon-like peptide 1 receptor agonists [GLP-1RAs]). Design, Setting, and Participants: Cluster randomized clinical trial with 43 US cardiology clinics recruiting participants from July 2019 through May 2022 and follow-up through December 2022. The participants were adults with type 2 diabetes and atherosclerotic cardiovascular disease not already taking all 3 groups of evidence-based therapies. Interventions: Assessing local barriers, developing care pathways, coordinating care, educating clinicians, reporting data back to the clinics, and providing tools for participants (n = 459) vs usual care per practice guidelines (n = 590). Main Outcomes and Measures: The primary outcome was the proportion of participants prescribed all 3 groups of recommended therapies at 6 to 12 months after enrollment. The secondary outcomes included changes in atherosclerotic cardiovascular disease risk factors and a composite outcome of all-cause death or hospitalization for myocardial infarction, stroke, decompensated heart failure, or urgent revascularization (the trial was not powered to show these differences). Results: Of 1049 participants enrolled (459 at 20 intervention clinics and 590 at 23 usual care clinics), the median age was 70 years and there were 338 women (32.2%), 173 Black participants (16.5%), and 90 Hispanic participants (8.6%). At the last follow-up visit (12 months for 97.3% of participants), those in the intervention group were more likely to be prescribed all 3 therapies (173/457 [37.9%]) vs the usual care group (85/588 [14.5%]), which is a difference of 23.4% (adjusted odds ratio [OR], 4.38 [95% CI, 2.49 to 7.71]; P < .001) and were more likely to be prescribed each of the 3 therapies (change from baseline in high-intensity statins from 66.5% to 70.7% for intervention vs from 58.2% to 56.8% for usual care [adjusted OR, 1.73; 95% CI, 1.06-2.83]; ACEIs or ARBs: from 75.1% to 81.4% for intervention vs from 69.6% to 68.4% for usual care [adjusted OR, 1.82; 95% CI, 1.14-2.91]; SGLT2 inhibitors and/or GLP-1RAs: from 12.3% to 60.4% for intervention vs from 14.5% to 35.5% for usual care [adjusted OR, 3.11; 95% CI, 2.08-4.64]). The intervention was not associated with changes in atherosclerotic cardiovascular disease risk factors. The composite secondary outcome occurred in 23 of 457 participants (5%) in the intervention group vs 40 of 588 participants (6.8%) in the usual care group (adjusted hazard ratio, 0.79 [95% CI, 0.46 to 1.33]). Conclusions and Relevance: A coordinated, multifaceted intervention increased prescription of 3 groups of evidence-based therapies in adults with type 2 diabetes and atherosclerotic cardiovascular disease. Trial Registration: ClinicalTrials.gov Identifier: NCT03936660.

Incorporating SGLT2i and GLP-1RA for Cardiovascular and Kidney Disease Risk Reduction: Call for Action to the Cardiology Community.

Multiple sodium glucose cotransporter-2 inhibitors (SGLT-2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) have been shown to impart significant cardiovascular and kidney benefits, but are underused in clinical practice. Both SGLT-2i and GLP-1RA were first studied as glucose-lowering drugs, which may have impeded uptake by cardiologists in the wake of proven cardiovascular efficacy. Their significant effect on cardiovascular and kidney outcomes, which are largely independent of glucose-lowering effects, must drive a broader use of these drugs. Cardiologists are 3 times more likely than endocrinologists to see patients with both type 2 diabetes and cardiovascular disease, thus they are ideally positioned to share responsibility for SGLT-2i and GLP-1RA treatment with primary care providers. In order to increase adoption, SGLT-2i and GLP-1RA must be reframed as primarily cardiovascular and kidney disease risk-reducing agents with a side effect of glucose-lowering. Coordinated and multifaceted interventions engaging clinicians, patients, payers, professional societies, and health systems must be implemented to incentivize the adoption of these medications as part of routine cardiovascular and kidney care. Greater use of SGLT-2i and GLP-1RA will improve outcomes for patients with type 2 diabetes at high risk for cardiovascular and kidney disease.

The Association of Digital Health Application Use With Heart Failure Care and Outcomes: Insights From CONNECT-HF.

BACKGROUND: It is unknown whether digital applications can improve guideline-directed medical therapy (GDMT) and outcomes in heart failure with reduced ejection fraction (HFrEF). METHODS AND RESULTS: Care Optimization Through Patient and Hospital Engagement Clinical Trial for Heart Failure trial (CONNECT-HF) included an optional, prospective ancillary study of a mobile health application among patients hospitalized due to HFrEF. Digital users were matched to nonusers from the usual-care group. Coprimary outcomes included change in opportunity-based composite HF quality scores and HF rehospitalization or all-cause mortality. Among 2431 patients offered digital applications across the United States, 1526 (63%) had limited digital access or insufficient data, 425 (17%) were digital users, and 480 (20%) declined use. Digital users were similar in age to those who declined use (mean 58 vs 60 years; P = 0.031). Digital users (n = 368) vs matched nonusers (n = 368) had improved composite HF quality scores (48.0% vs 43.6%; + 4.76% [3.27-6.24]; P = 0.001) and composite clinical outcomes (33.0% vs 39.6%; HR 0.76 [0.59-0.97]; P = 0.027). CONCLUSIONS: Among participants in the CONNECT-HF trial, use of digital applications was modest but was associated with higher HF quality-of-care scores, including use of GDMT and better clinical outcomes. Although cause and effect cannot be determined from this study, the application of technology to guide GDMT use and dosing among patients with HFrEF warrants further investigation.

Health System-Level Performance in Prescribing Guideline-Directed Medical Therapy for Patients With Heart Failure With Reduced Ejection Fraction: Results From the CONNECT-HF Trial.

BACKGROUND: Health system-level interventions to improve use of guideline-directed medical therapy (GDMT) often fail in the acute care setting. We sought to identify factors associated with high performance in adoption of GDMT among health systems in CONNECT-HF. METHODS AND RESULTS: Site-level composite quality scores were calculated at discharge and last follow-up. Site performance was defined as the average change in score from baseline to last follow-up and analyzed by performance tertile using a mixed-effects model with baseline performance as a fixed effect and site as a random effect. Among 150 randomized sites, the mean 12-month improvement in GDMT was 1.8% (-26.4% to 60.0%). Achievement of 50% or more of the target dose for angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, angiotensin receptor-neprilysin inhibitors, and beta-blockers at 12 months was modest, even at the highest performing sites (median 29.6% [23%, 41%] and 41.2% [29%, 50%]). Sites achieving higher GDMT scores had care teams that included social workers and pharmacists, as well as patients who were able to afford medications and access medication lists in the electronic health record. CONCLUSIONS: Substantial gaps in site-level use of GDMT were found, even among the highest performing sites. The failure of hospital-level interventions to improve quality metrics suggests that a team-based approach to care and improved patient access to medications are needed for postdischarge success.

Effect of a Hospital and Postdischarge Quality Improvement Intervention on Clinical Outcomes and Quality of Care for Patients With Heart Failure With Reduced Ejection Fraction: The CONNECT-HF Randomized Clinical Trial.

Importance: Adoption of guideline-directed medical therapy for patients with heart failure is variable. Interventions to improve guideline-directed medical therapy have failed to consistently achieve target metrics, and limited data exist to inform efforts to improve heart failure quality of care. Objective: To evaluate the effect of a hospital and postdischarge quality improvement intervention compared with usual care on heart failure outcomes and care. Design, Setting, and Participants: This cluster randomized clinical trial was conducted at 161 US hospitals and included 5647 patients (2675 intervention vs 2972 usual care) followed up after a hospital discharge for acute heart failure with reduced ejection fraction (HFrEF). The trial was performed from 2017 to 2020, and the date of final follow-up was August 31, 2020. Interventions: Hospitals (n = 82) randomized to a hospital and postdischarge quality improvement intervention received regular education of clinicians by a trained group of heart failure and quality improvement experts and audit and feedback on heart failure process measures (eg, use of guideline-directed medical therapy for HFrEF) and outcomes. Hospitals (n = 79) randomized to usual care received access to a generalized heart failure education website. Main Outcomes and Measures: The coprimary outcomes were a composite of first heart failure rehospitalization or all-cause mortality and change in an opportunity-based composite score for heart failure quality (percentage of recommendations followed). Results: Among 5647 patients (mean age, 63 years; 33% women; 38% Black; 87% chronic heart failure; 49% recent heart failure hospitalization), vital status was known for 5636 (99.8%). Heart failure rehospitalization or all-cause mortality occurred in 38.6% in the intervention group vs 39.2% in usual care (adjusted hazard ratio, 0.92 [95% CI, 0.81 to 1.05). The baseline quality-of-care score was 42.1% vs 45.5%, respectively, and the change from baseline to follow-up was 2.3% vs -1.0% (difference, 3.3% [95% CI, -0.8% to 7.3%]), with no significant difference between the 2 groups in the odds of achieving a higher composite quality score at last follow-up (adjusted odds ratio, 1.06 [95% CI, 0.93 to 1.21]). Conclusions and Relevance: Among patients with HFrEF in hospitals randomized to a hospital and postdischarge quality improvement intervention vs usual care, there was no significant difference in time to first heart failure rehospitalization or death, or in change in a composite heart failure quality-of-care score. Trial Registration: ClinicalTrials.gov Identifier: NCT03035474.

Relationship Between Operator Volume and Long-Term Outcomes After Percutaneous Coronary Intervention.

BACKGROUND: Although many studies show an inverse association between operator procedural volume and short-term adverse outcomes after percutaneous coronary intervention (PCI), the association between procedural volume and longer-term outcomes is unknown. METHODS: Using the National Cardiovascular Data Registry CathPCI registry data linked with Medicare claims data, we examined the association between operator PCI volume and long-term outcomes among patients ≥65 years of age. Operators were stratified by average annual PCI volume (counting PCIs performed in patients of all ages): low- (<50 PCIs), intermediate- (50-100), and high- (>100) volume operators. One-year unadjusted rates of death and major adverse coronary events (MACEs; defined as death, readmission for myocardial infarction, or unplanned coronary revascularization) were calculated with Kaplan-Meier methods. The proportional hazards assumption was not met, and risk-adjusted associations between operator volume and outcomes were calculated separately from the time of PCI to hospital discharge and from hospital discharge to 1-year follow-up. RESULTS: Between July 1, 2009, and December 31, 2014, 723 644 PCI procedures were performed by 8936 operators: 2553 high-, 2878 intermediate-, and 3505 low-volume operators. Compared with high- and intermediate-volume operators, low-volume operators more often performed emergency PCI, and their patients had fewer cardiovascular comorbidities. Over 1-year follow-up, 15.9% of patients treated by low-volume operators had a MACE compared with 16.9% of patients treated by high-volume operators ( P=0.004). After multivariable adjustment, intermediate- and high-volume operators had a significantly lower rate of in-hospital death than low-volume operators (odds ratio, 0.91; 95% CI, 0.86-0.96 for intermediate versus low; odds ratio, 0.79; 95% CI, 0.75-0.83 for high versus low). There were no significant differences in rates of MACEs, death, myocardial infarction, or unplanned revascularization between operator cohorts from hospital discharge to 1-year follow-up (adjusted hazard ratio for MACEs, 0.99; 95% CI, 0.96-1.01 for intermediate versus low; hazard ratio, 1.01; 95% CI, 0.99-1.04 for high versus low). CONCLUSIONS: Unadjusted 1-year outcomes after PCI were worse for older adults treated by operators with higher annual volume; however, patients treated by these operators had more cardiovascular comorbidities. After risk adjustment, higher operator volume was associated with lower in-hospital mortality and no difference in postdischarge MACEs.

Care Optimization Through Patient and Hospital Engagement Clinical Trial for Heart Failure: Rationale and design of CONNECT-HF.

Many therapies have been shown to improve outcomes for patients with heart failure (HF) in controlled settings, but there are limited data available to inform best practices for hospital and post-discharge quality improvement initiatives. The CONNECT-HF study is a prospective, cluster-randomized trial of 161 hospitals in the United States with a 2×2 factorial design. The study is designed to assess the effect of a hospital and post-discharge quality improvement intervention compared with usual care (primary objective) on HF outcomes and quality-of-care, as well as to evaluate the effect of hospitals implementing a patient-level digital intervention compared with usual care (secondary objective). The hospital and post-discharge intervention includes audit and feedback on HF clinical process measures and outcomes for patients with HF with reduced ejection fraction (HFrEF) paired with education to sites and clinicians by a trained, nationally representative group of HF and quality improvement experts. The patient-level digital intervention is an optional ancillary study and includes a mobile application and behavioral tools that are intended to facilitate improved use of guideline-directed recommendations for self-monitoring and self-management of activity and medications for HFrEF. The effects of the interventions will be measured through an opportunity-based composite score on quality and time-to-first HF readmission or death among patients with HFrEF who present to study hospitals with acute HF and who consent to participate. The CONNECT-HF study is evaluating approaches for implementing HF guideline recommendations into practice and is one of the largest HF implementation science trials performed to date.

Hospital Variation in Adherence Rates to Secondary Prevention Medications and the Implications on Quality.

BACKGROUND: Medication adherence is important to improve the long-term outcomes after acute myocardial infarction (MI). We hypothesized that there is significant variation among US hospitals in terms of medication adherence after MI, and that patients treated at hospitals with higher medication adherence after MI will have better long-term cardiovascular outcomes. METHODS: We identified 19 704 Medicare patients discharged after acute MI from 347 US hospitals participating in the ACTION Registry-GWTG (Acute Coronary Treatment and Intervention Outcomes Network Registry-Get With the Guidelines) from January 2, 2007, to October 1, 2010. Using linked Medicare Part D prescription filling data, medication adherence was defined as proportion of days covered >80% within 90 days after discharge. Cox proportional hazards modeling was used to compare 2-year major adverse cardiovascular events among hospitals with high, moderate, and low 90-day medication adherence. RESULTS: By 90 days after MI, overall rates of adherence to medications prescribed at discharge were 68% for ß-blockers, 63% for statins, 64% for angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and 72% for thienopyridines. Adherence to these medications up to 90 days varied significantly among hospitals: ß-blockers (proportion of days covered >80%; 59% to 75%), statins (55% to 69%), thienopyridines (64% to 77%), and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (57% to 69%). Compared with hospitals in the lowest quartile of 90-day composite medication adherence, hospitals with the highest adherence had lower unadjusted and adjusted 2-year major adverse cardiovascular event risk (27.5% versus 35.3%; adjusted hazard ratio, 0.88; 95% confidence interval, 0.80-0.96). High-adherence hospitals also had lower adjusted rates of death or readmission (hazard ratio, 0.90; 95% confidence interval, 0.85-0.96), whereas there was no difference in mortality after adjustment. CONCLUSIONS: Use of secondary prevention medications after discharge varies significantly among US hospitals and is inversely associated with 2-year outcomes. Hospitals may improve medication adherence after discharge and patient outcomes through better coordination of care between inpatient and outpatient settings.

Glycoprotein IIb/IIIa inhibitor use in patients with acute myocardial infarction undergoing PCI: Insights from the TRANSLATE ACS study.

INTRODUCTION: Concomitant use of glycoprotein IIb/IIIa inhibitors (GPI) and P2Y12 inhibitors increases bleeding risk. How GPIs are being used with faster onset, higher potency P2Y12 inhibitors are unclear. METHODS AND RESULTS: We studied 11,781 myocardial infarction (MI) patients treated with percutaneous coronary intervention (PCI) at 233 hospitals in the TRANSLATE ACS study (2010-2012). We used propensity matching to compare 6-week major adverse cardiac events (MACE: death, recurrent MI, stroke, or unplanned revascularization) and BARC 2+ bleeding events between patients who did and did not receive planned GPI. Planned and bailout GPI were used in 4,983 (42.2%) and 229 (4.4%) MI patients undergoing PCI, respectively. Patients receiving planned GPI were younger (58 vs. 61 years), more likely to present with STEMI (62.6% vs. 45.4%) or have stent thrombosis (4.2% vs. 2.1%, all P < 0.001) than those without planned GPI use. Planned GPI was used less often with prasugrel/ticagrelor versus clopidogrel (37.1% vs. 43.3%), or when any P2Y12 inhibitor was given >6 hr prior to PCI versus earlier (27.8% vs. 44.4%, both P < 0.01). After propensity matching, planned GPI use was not associated with any difference in MACE (6.4% vs. 5.5% OR 1.18; 95% CI: 0.99-1.57), however, the risk of BARC 2+ bleeding was higher in patients who received planned GPI (11.3% vs. 8.7%; OR 1.34; 95% CI: 1.13-1.59). CONCLUSION: Planned GPI use as reported by practicing physicians was prevalent between 2010 and 2012 and was associated with increased risk of bleeding but not lower MACE.

Effect of Medication Co-payment Vouchers on P2Y12 Inhibitor Use and Major Adverse Cardiovascular Events Among Patients With Myocardial Infarction: The ARTEMIS Randomized Clinical Trial.

Importance: Despite guideline recommendations, many patients discontinue P2Y12 inhibitor therapy earlier than the recommended 1 year after myocardial infarction (MI), and higher-potency P2Y12 inhibitors are underutilized. Cost is frequently cited as an explanation for both of these observations. Objective: To determine whether removing co-payment barriers increases P2Y12 inhibitor persistence and lowers risk of major adverse cardiovascular events (MACE). Design, Setting, and Participants: Cluster randomized clinical trial among 301 hospitals enrolling adult patients with acute MI (June 5, 2015, through September 30, 2016); patients were followed up for 1 year after discharge (final date of follow-up was October 23, 2017), with blinded adjudication of MACE; choice of P2Y12 inhibitor was per clinician discretion. Interventions: Hospitals randomized to the intervention (n = 131 [6436 patients]) provided patients with co-payment vouchers for clopidogrel or ticagrelor for 1 year (median voucher value for a 30-day supply, $137 [25th-75th percentile, $20-$339]). Hospitals randomized to usual care (n = 156 [4565 patients]) did not provide study vouchers. Main Outcomes and Measures: Independent coprimary outcomes were patient-reported persistence with P2Y12 inhibitor (defined as continued treatment without gap in use ≥30 days) and MACE (death, recurrent MI, or stroke) at 1 year among patients discharged with a prescription for clopidogrel or ticagrelor. Results: Among 11 001 enrolled patients (median age, 62 years; 3459 [31%] women), 10 102 patients were discharged with prescriptions for clopidogrel or ticagrelor (clopidogrel prescribed to 2317 [36.0%] in the intervention group and 2497 [54.7%] in the usual care group), 4393 of 6135 patients (72%) in the intervention group used the voucher, and follow-up data at 1 year were available for 10 802 patients (98.2%). Patient-reported persistence with P2Y12 inhibitors at 1 year was higher in the intervention group than in the control group (unadjusted rates, 5340/6135 [87.0%] vs 3324/3967 [83.8%], respectively; P < .001; adjusted difference, 2.3% [95% CI, 0.4% to 4.1%]; adjusted odds ratio, 1.19 [95% CI, 1.02 to 1.40]). There was no significant difference in MACE at 1 year between intervention and usual care groups (unadjusted cumulative incidence, 10.2% vs 10.6%; P = .65; adjusted difference, 0.66% [95% CI, -0.73% to 2.06%]; adjusted hazard ratio, 1.07 [95% CI, 0.93 to 1.25]). Conclusions and Relevance: Among patients with MI, provision of vouchers to offset medication co-payments for P2Y12 inhibitors, compared with no vouchers, resulted in a 3.3% absolute increase in patient-reported persistence with P2Y12 inhibitors and no significant reduction in 1-year MACE outcomes. Trial Registration: ClinicalTrials.gov Identifier: NCT02406677.

Race and Sex Differences in Post-Myocardial Infarction Angina Frequency and Risk of 1-Year Unplanned Rehospitalization.

BACKGROUND: Race and sex disparities in in-hospital treatment and outcomes of patients with acute myocardial infarction (MI) have been described, but little is known about race and sex differences in post-MI angina and long-term risk of unplanned rehospitalization. We examined race and sex differences in post-MI angina frequency and 1-year unplanned rehospitalization to identify factors associated with unplanned rehospitalization, testing for whether race and sex modify these relationships. METHODS: Using TRANSLATE-ACS (Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events after Acute Coronary Syndrome) data, we examined 6-week and 1-year angina frequency and 1-year unplanned rehospitalization stratified by race and sex among MI patients treated with percutaneous coronary intervention. We used multivariable logistic regression to assess factors associated with unplanned rehospitalization and tested for interactions among angina frequency, race, and sex. RESULTS: A total of 11 595 MI patients survived to 1 year postdischarge; there were 66.6% white male patients, 24.3% white female patients, 5.3% black male patients, and 3.8% black female patients. Overall, 29.7% had angina at 6 weeks, and 20.6% had angina at 1 year postdischarge. Relative to white patients, black patients were more likely to have angina at 6 weeks (female: 44.2% versus 31.8%; male: 33.5% versus 27.1%; both P<0.0001) and 1 year (female: 49.4% versus 38.9%; male: 46.3% versus 31.1%; both P<0.0001). Rates of 1-year unplanned rehospitalization were highest among black female patients (44.1%), followed by white female patients (38.4%), black male patients (36.4%), and white male patients (30.2%, P<0.0001). In the multivariable model, 6-week angina was most strongly associated with unplanned rehospitalization (hazard ratio, 1.49; 95% confidence interval, 1.36-1.62; P<0.0001); this relationship was not modified by race or sex (adjusted 3-way Pinteraction=0.41). CONCLUSIONS: One-fifth of MI patients treated with percutaneous coronary intervention report 1-year postdischarge angina, with black and female patients more likely to have angina and to be rehospitalized. Better treatment of post-MI angina may improve patient quality of life and quality of care and help to lower rates of rehospitalization overall and particularly among black and female patients, given their high prevalence of post-MI angina.

Hospital evaluation of health literacy and associated outcomes in patients after acute myocardial infarction.

BACKGROUND: Low health literacy is common in the United States and may affect outcomes after myocardial infarction (MI). How often hospitals screen for low health literacy is unknown. METHODS: We surveyed 122 hospitals in the TRANSLATE-ACS study and divided them into those that reported routinely (>75% of patients), selectively (1%-75%), or never (0%) screening MI patients for low health literacy prior to discharge. We performed logistic regression with random intercepts to compare 6-week and 6-month patient-reported medication adherence and multivariable Cox regression to compare 1-year major adverse cardiovascular events and all-cause readmission risks between hospital groups. RESULTS: Overall, 25 (20.5%), 47 (38.5%), and 50 (41.0%) hospitals reported routinely, selectively, or never screening patients for low health literacy, respectively. Patients discharged from hospitals that routinely screened were more likely to report 6-week medication adherence [routinely: adjusted odds ratio (OR) 1.26, 95% CI 1.01-1.57; selectively: adjusted OR 1.19, 95% CI 1.00-1.43, both referenced to those discharged from hospitals that never screened]. Compared with hospitals that never screened health literacy, 1-year major adverse cardiovascular events were similar for hospitals that reported routinely screening (adjusted HR 0.92, 95% CI 0.75-1.14) or selectively screening (adjusted HR 1.01, 95% CI 0.84-1.21). Hospitals that reported selectively screening health literacy were associated with a lower adjusted risk of 1-year all-cause readmission (adjusted HR 0.89, 95% CI 0.79-1.00, P=.041). CONCLUSION: Only a minority of US hospitals routinely screen MI patients for low health literacy. Hospital screening was associated with higher medication adherence and lower readmission risk. Further investigation is needed to understand how inpatient screening can be implemented to improve longitudinal post-MI care.

Adoption of radial access and comparison of outcomes to femoral access in percutaneous coronary intervention: an updated report from the national cardiovascular data registry (2007-2012).

BACKGROUND: Radial access for percutaneous coronary intervention (r-PCI) is associated with reduced vascular complications; however, previous reports have shown that <2% of percutaneous coronary intervention (PCI) procedures in the United States are performed via the radial approach. Our aims were to evaluate temporal trends in r-PCI and compare procedural outcomes between r-PCI and transfemoral PCI. METHODS AND RESULTS: We conducted a retrospective cohort study from the CathPCI registry (n=2 820 874 procedures from 1381 sites) between January 2007 and September 2012. Multivariable logistic regression models were used to evaluate the adjusted association between r-PCI and bleeding, vascular complications, and procedural success, using transfemoral PCI as the reference. Outcomes in high-risk subgroups such as age ≥75 years, women, and patients with acute coronary syndrome were also examined. The proportion of r-PCI procedures increased from 1.2% in quarter 1 2007 to 16.1% in quarter 3 2012 and accounted for 6.3% of total procedures from 2007 to 2012 (n=178 643). After multivariable adjustment, r-PCI use in the studied cohort of patients was associated with lower risk of bleeding (adjusted odds ratio, 0.51; 95% confidence interval, 0.49-0.54) and lower risk of vascular complications (adjusted odds ratio, 0.39; 95% confidence interval, 0.31-0.50) in comparison with transfemoral PCI. The reduction in bleeding and vascular complications was consistent across important subgroups of age, sex, and clinical presentation. CONCLUSIONS: There has been increasing adoption of r-PCI in the United States. Transradial PCI now accounts for 1 of 6 PCIs performed in contemporary clinical practice. In comparison with traditional femoral access, transradial PCI is associated with lower vascular and bleeding complication rates.

Assessing stroke patients for rehabilitation during the acute hospitalization: findings from the get with the guidelines-stroke program.

OBJECTIVE: To examine the frequency and determinants of an assessment for rehabilitation during the hospitalization for acute stroke. DESIGN: Prospective cohort of patients admitted with acute stroke in the Get With The Guidelines-Stroke (GWTG-Stroke) program from January 8, 2008, to March 31, 2011. SETTING: Acute hospitals (n=1532) in the United States participating in the GWTG-Stroke program. PARTICIPANTS: Adults with a stroke diagnosis (N=616,982) from a GWTG-Stroke-participating acute hospital. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Documentation of an assessment for rehabilitation services during the acute hospitalization. RESULTS: Overall, almost 90% of stroke patients had documentation of an acute assessment for rehabilitation. In multivariable analysis, patients significantly more likely to be assessed for rehabilitation were younger, male, black or of other nonwhite races (Asian, American Indian, Alaska Native, Native Hawaiian, or Pacific Islander) when compared with white, independently ambulating before admission, and admitted from the community. Patients who received a stroke consult, cared for in a stroke unit, and treated in the northeast region of the United States were also more likely to be assessed. CONCLUSIONS: There is evidence that rehabilitation was considered for 90% of acute stroke patients in this sample. Future research is needed to examine what assessments are conducted and by whom, and how these are used to determine the appropriate level of rehabilitation care for their needs.

Challenge in Predicting Persistence to P2Y12 Inhibitors: A Perspective From the ARTEMIS Trial.

Background Premature discontinuation of P2Y12 inhibitor therapy has been associated with adverse cardiac events, which might be preventable by improving medication persistence. Current risk models have limited ability to predict patients at risk of P2Y12 inhibitor nonpersistence. Methods and Results ARTEMIS (Affordability and Real-World Antiplatelet Treatment Effectiveness after Myocardial Infarction Study) was a randomized, controlled trial testing the impact of a copayment assistance intervention on P2Y12 inhibitor persistence and outcomes. Among 6212 patients post myocardial infarction with a planned 1-year course of P2Y12 inhibitor therapy, nonpersistence was defined as a gap in P2Y12 inhibitor filled >30 days by pharmacy fill data. We developed a predictive model for 1-year P2Y12 inhibitor nonpersistence among patients randomized to usual care. P2Y12 inhibitor nonpersistence rates were 23.8% (95% CI, 22.7%-24.8%) at 30 days and 47.9% (46.6%-49.1%) at 1 year; the majority of these patients had in-hospital percutaneous coronary intervention. Patients who received the copayment assistance intervention had nonpersistence rates of 22.0% (20.7%-23.3%) at 30 days and 45.3% (43.8%-46.9%) at 1 year. A 53-variable multivariable model predicting 1-year persistence had a C-index of 0.63 (optimism-corrected C-index 0.58). Model discrimination did not improve with inclusion of patient-reported perceptions about disease, medication-taking beliefs, and prior medication-filling behavior in addition to demographic and medical history data (C-index 0.62). Conclusions Despite addition of patient-reported variables, models predicting persistence with P2Y12 inhibitor therapy performed poorly, thereby suggesting the need for continued patient and clinician education on the importance of P2Y12 inhibitor therapy after acute myocardial infarction.
