Background Patient satisfaction with therapy is an important metric of care quality and has been associated with greater medication persistence. We evaluated the association of patient satisfaction with warfarin therapy to other metrics of anticoagulation care quality and clinical outcomes among patients with atrial fibrillation ( AF ). Methods and Results Using data from the ORBIT ‐ AF (Outcomes Registry for Better Informed Treatment of Atrial Fibrillation) registry, patients were identified with AF who were taking warfarin and had completed an Anti‐Clot Treatment Scale ( ACTS ) questionnaire, a validated metric of patient‐reported burden and benefit of oral anticoagulation. Multivariate regressions were used to determine association of ACTS burden and benefit scores with time in therapeutic international normalized ratio range ( TTR ; both ≥75% and ≥60%), warfarin discontinuation, and clinical outcomes (death, stroke, major bleed, and all‐cause hospitalization). Among 1514 patients with AF on warfarin therapy (75±10 years; 42% women; CHA 2 DS 2 ‐ VAS c 3.9±1.7), those most burdened with warfarin therapy were younger and more likely to be women, have paroxysmal AF , and to be treated with antiarrhythmic drugs. After adjustment for covariates, ACTS burden scores were independent of TTR ( TTR ≥75%: odds ratio, 1.01 [95% CI , 0.99–1.03]; TTR ≥60%: odds ratio, 1.01 [95% CI , 0.98–1.05]), warfarin discontinuation (odds ratio, 0.99; 95% CI , 0.97–1.01), or clinical outcomes. ACTS benefit scores were also not associated with TTR , warfarin discontinuation, or clinical outcomes. Conclusions In a large registry of patients with AF taking warfarin, ACTS scores provided independent information beyond other traditional metrics of oral anticoagulation care quality and identified patient groups at high risk for dissatisfaction with warfarin therapy.

Introduction: Shared decision making (SDM) incorporates patient and physician values and preferences into treatment selection. While multiple therapeutic options are available for stroke prevention in atrial fibrillation (AF), few studies have examined factors associated with SDM regarding choice of antithrombotic strategy. Methods: We evaluated survey data from 1006 patients with new-onset AF enrolled at 56 sites participating in a substudy of the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT II), an outpatient AF registry in the US. Patients were asked: “When choosing your blood thinner(s), who made this treatment decision?”, and SDM was defined as a response of “equally me and my healthcare provider (HCP)”, “mostly me” or “entirely me”, while no SDM was defined as a response of “mostly my HCP” or “entirely my HCP”. Multivariable logistic regression models evaluated associations between 13 patient-level factors, self-reported understanding of treatment options, and SDM for antithrombotic therapy. Results: Most patients allowed their HCP to make the therapeutic decisions on antithrombotic strategy, with 246 (24.5%) reporting SDM. Patients reporting SDM were more often female (47.2% vs. 40.5%) and were more frequently insured by Medicare (40.2% vs. 34.5%) than patients reporting no SDM. Among patients taking warfarin, median time in therapeutic range was higher among patients reporting SDM than among those not reporting SDM. In multivariable models, chronic obstructive pulmonary disease was associated with lower odds of SDM while self-reported understanding of blood thinner options was associated with higher odds of SDM (Table). Conclusion: One in four patients in an outpatient AF registry reported that their current antithrombotic strategy was the result of a shared decision making process. Additional work is need to determine whether patient-reported SDM is associated with medication adherence and outcomes of therapy.

Abstract Myeloproliferative neoplasms (MPN), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, have a propensity to evolve into accelerated and blast-phase disease (MPN-AP/BP), carrying a dismal prognosis. Conventional antileukemia therapy has limited efficacy in this setting. Thus, MPN-AP/BP is an urgent unmet clinical need. Modest responses to hypomethylating agents and single-agent ruxolitinib have been reported. More recently, combination of ruxolitinib and decitabine has demonstrated synergistic in vitro activity in human and murine systems. These observations led us to conduct a phase 1 study to explore the safety of combined decitabine and dose-escalated ruxolitinib in patients with MPN-AP/BP. A total of 21 patients were accrued to this multicenter study. Ruxolitinib was administered at doses of 10, 15, 25, or 50 mg twice daily in combination with decitabine (20 mg/m2 per day for 5 days) in 28-day cycles. The maximum tolerated dose was not reached. The most common reasons for study discontinuation were toxicity/adverse events (37%) and disease progression (21%). Fourteen patients died during study treatment period or follow-up. The median overall survival for patients on study was 7.9 months (95% confidence interval, 4.1-not reached). Among evaluable patients, the overall response rate by protocol-defined criteria (complete remission with incomplete count recovery + partial remission) was 9/17 (53%) and by intention-to-treat analysis was 9/21 (42.9%). The combination of decitabine and ruxolitinib was generally well tolerated by patients with MPN-AP/BP and demonstrates potentially promising clinical activity. A phase 2 trial evaluating the efficacy of this combination regimen is ongoing within the Myeloproliferative Disorder Research Consortium.

Objective The association with B-type natriuretic peptide (BNP), disease progression and outcomes in patients with atrial fibrillation (AF) has not been thoroughly investigated. Methods We evaluated the association between BNP levels and outcomes, including AF progression, composite outcome of major adverse cardiovascular or neurological events (MACNE) and major bleeding, via pooled logistic regression and Cox frailty models in Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II registry. AF progression was defined as either paroxysmal becoming persistent or permanent, or persistent becoming permanent at any follow-up. Results Among 13 375 patients with AF, 2797 with BNP values at baseline (median age (IQR), 72.0 (63.0–80.0) years; 43.0% women; median BNP, 238 (102–502) ng/L; 42.3% prior heart failure) were included in the models evaluating the association between BNP levels and MACNE or major bleeding. Of these, 1282 patients with paroxysmal or persistent AF at baseline were analysed in AF progression model. The likelihood of AF progression (adjusted OR, 1.11 for every 100 ng/mL; 95% CI 1.03 to 1.19) and MACNE (adjusted HR, 1.11 for every doubling in BNP values; 95% CI 1.01 to 1.22) increased with BNP concentration, while the elevated BNP values were not associated with increased risks of major bleeding. BNP values improved the risk prediction of AF progression and MACNE when added to conventional risk estimates. Conclusions BNP levels are associated with increased risk of AF progression and cardiovascular outcomes in patients with AF. Further studies are required to assess whether biomarker-based risk stratification improves patient outcomes. Clinical trial registration NCT01701817 .
