Compliance of Atrial Fibrillation Treatment with the Atrial Fibrillation Better Care (ABC) Pathway Improves the Clinical Outcomes in the Middle East Population: A Report from the Gulf Survey of Atrial Fibrillation Events (SAFE) Registry.

ABSTRACT: Atrial fibrillation (AF) is associated with substantially increased risk of cardiovascular events and overall mortality. The Atrial fibrillation Better Care (A-Avoid stroke, B-Better symptom management, C-Cardiovascular and comorbidity risk management) pathway provides a simple and comprehensive approach for integrated AF therapy. This study's goals were to evaluate the ABC pathway compliance and determine the main gaps in AF management in the Middle East population, and to assess the impact of ABC pathway adherence on the all-cause mortality and composite outcome in AF patients. 2021 patients (mean age 57; 52% male) from the Gulf SAFE registry were studied. We evaluated: A-appropriate implementation of OACs according to CHA2DS2-VASc score; B-symptom control according to European Heart Rhythm Association (EHRA) symptom scale; C-proper cardiovascular comorbidities management. The primary endpoints were the composite cardiovascular outcome (ischemic stroke or systemic embolism, all-cause death and cardiovascular hospitalization) and all-cause mortality. One-hundred and sixty-eight (8.3%) patients were optimally managed according to adherence with the ABC pathway. Over the one-year follow up (FU), there were 578 composite outcome events and 224 deaths. Patients managed with integrated care had significantly lower rates for the composite outcome and mortality comparing to non-ABC group (20.8% vs. 29.3%, p = 0.02 and 7.3% vs. 13.1%, p = 0.033, respectively). On multivariable analysis, ABC compliance was independently associated with reduced risk of composite outcome (HR 0.53; 95% CI 0.36-0.8, p = 0.002) and death (HR 0.46; 95% CI 0.25-0.86, p = 0.015). Integrated ABC pathway adherent care resulted in the reduced composite outcome and all-cause mortality in AF patients from Middle East, highlighting the necessity of promoting comprehensive holistic and integrated care management of AF.

Project description:BackgroundClinical complexity is increasingly prevalent among patients with atrial fibrillation (AF). The 'Atrial fibrillation Better Care' (ABC) pathway approach has been proposed to streamline a more holistic and integrated approach to AF care; however, there are limited data on its usefulness among clinically complex patients. We aim to determine the impact of ABC pathway in a contemporary cohort of clinically complex AF patients.MethodsFrom the ESC-EHRA EORP-AF General Long-Term Registry, we analysed clinically complex AF patients, defined as the presence of frailty, multimorbidity and/or polypharmacy. A K-medoids cluster analysis was performed to identify different groups of clinical complexity. The impact of an ABC-adherent approach on major outcomes was analysed through Cox-regression analyses and delay of event (DoE) analyses.ResultsAmong 9966 AF patients included, 8289 (83.1%) were clinically complex. Adherence to the ABC pathway in the clinically complex group reduced the risk of all-cause death (adjusted HR [aHR]: 0.72, 95%CI 0.58-0.91), major adverse cardiovascular events (MACEs; aHR: 0.68, 95%CI 0.52-0.87) and composite outcome (aHR: 0.70, 95%CI: 0.58-0.85). Adherence to the ABC pathway was associated with a significant reduction in the risk of death (aHR: 0.74, 95%CI 0.56-0.98) and composite outcome (aHR: 0.76, 95%CI 0.60-0.96) also in the high-complexity cluster; similar trends were observed for MACEs. In DoE analyses, an ABC-adherent approach resulted in significant gains in event-free survival for all the outcomes investigated in clinically complex patients. Based on absolute risk reduction at 1 year of follow-up, the number needed to treat for ABC pathway adherence was 24 for all-cause death, 31 for MACEs and 20 for the composite outcome.ConclusionsAn ABC-adherent approach reduces the risk of major outcomes in clinically complex AF patients. Ensuring adherence to the ABC pathway is essential to improve clinical outcomes among clinically complex AF patients.

Project description:ImportanceBleeding and thrombotic events (eg, stroke and systemic embolism) are common in patients with atrial fibrillation (AF) taking warfarin sodium despite a well-established therapeutic range.ObjectiveTo evaluate whether history of therapeutic warfarin control in patients with AF is independently associated with subsequent bleeding or thrombotic events.Design, setting, and participantsIn this multicenter cohort study of 176 primary care, cardiology, and electrophysiology clinics in the United States, data were obtained during 51 830 visits among 10 137 patients with AF in the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF) Registry; 5545 patients treated with warfarin were included in the bleeding analysis, and 5635 patients were included in the thrombotic event analysis. Patient follow-up was performed from June 29, 2010, to November 30, 2014. Data analysis was performed from August 4, 2016, to February 15, 2019.ExposuresMultiple measures of warfarin control within the preceding 6 months were analyzed: time in therapeutic range of 2.0 to 3.0, most recent international normalized ratio (INR), percentage of time that a patient had interpolated INR values less than 2.0 or greater than 3.0, INR variance, INR range, and percentage of INR values in therapeutic range.Main outcomes and measuresAssociation of INR measures, alone or in combination, with clinical factors and risk for thrombotic events and bleeding during the subsequent 6 months was assessed post hoc using logistic regression models.ResultsA total of 5545 patients (mean [SD] age, 74.5 [9.8] years; 3184 [57.4%] male) with AF were included in the major bleeding analysis and 5635 patients (mean [SD] age, 74.5 [9.8] years; 3236 [57.4%] male) in the thrombotic event analysis. During a median follow-up of 1.5 years (interquartile range, 1.0-2.5 years), there were 339 major bleeds (6.1%) and 51 strokes (0.9%). Multiple metrics of warfarin control were individually associated with subsequent bleeding. After adjustment for clinical bleeding risk, 3 measures-time in therapeutic range (per 1-SD increase ≤55: adjusted odds ratio [aOR], 1.16; 95% CI, 1.02-1.32), variation in INR values (aOR, 1.32; 95% CI, 1.19-1.47), and maximum INR (aOR, 1.20; 95% CI, 1.10-1.31)-remained associated with bleeding risk. Adding INR variance to a clinical risk model slightly increased the C statistic from 0.68 to 0.69 and had a net reclassification improvement index of 0.028 (95% CI, -0.029 to 0.067). No INR measures were associated with subsequent stroke risk.Conclusions and relevanceThree metrics of prior warfarin control were associated with bleeding risk but only marginally more so than traditional clinical factors. This study did not identify any measures of INR control that were significantly associated with stroke risk.

Project description:Whereas insurance status has been previously associated with care patterns, little is currently known about the association between Medicaid insurance and the clinical characteristics, treatment, or outcomes of patients with atrial fibrillation (AF).We used data from adults with AF enrolled in the Outcomes Registry for Better Informed Treatment of AF (ORBIT-AF), a national outpatient registry conducted at 176 community, multispecialty sites. The primary outcome of interest was the proportion of patients prescribed any oral anticoagulation (OAC; warfarin or novel oral anticoagulants [NOAC]). Secondary outcomes of interest included the proportion of patients prescribed NOACs (dabigatran or rivaroxaban); time in therapeutic range (TTR) for warfarin users, all-cause mortality, stroke/systemic embolism, and major bleed. Of 10 133 patients, N=470 (4.6%) had Medicaid insurance. Medicaid patients were similarly likely to receive OAC at baseline (72.8% vs 76.3%; unadjusted P=0.079), but less likely to receive NOAC at baseline or follow-up (12.1% vs 16.3%; unadjusted P=0.019). After risk adjustment, Medicaid status was associated with lower use of OAC at baseline among patients with high stroke risk (odds ratio [OR]=0.68; 95% CI=0.49, 0.94), but was not associated with OAC use overall (OR=0.82; 95% CI=0.61, 1.09). Among warfarin users, median TTR was lower among Medicaid patients (60% vs 68%; P<0.0001; adjusted TTR difference, -2.9; 95% CI=-5.7, -0.2; P=0.04). Use of an NOAC over 2 years of follow-up was not statistically different by insurance. Compared with non-Medicaid patients, Medicaid patients had higher unadjusted rates of mortality, stroke/systemic embolism, and major bleeding; however, these differences were attenuated following adjustment for clinical characteristics.In a contemporary AF cohort, use of OAC overall and use of NOACs were not significantly lower among Medicaid patients relative to others. However, among warfarin users, Medicaid patients spent less time in therapeutic range compared with those with other forms of insurance.

Project description:BackgroundAlthough triple antithrombotic therapy (TAT) is recommended in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI), guidelines allow an option of dual antithrombotic therapy (DAT). This study assesses the everyday practice of 10 cardiology departments in antithrombotic therapy in AF patients undergoing PCI and its agreement with current guidelines.MethodsThis analysis included medical data of AF patients enrolled in the prospective, observational registry (The POLish Atrial Fibrillation-POL-AF) that underwent PCI [elective or due to acute coronary syndrome (ACS)].ResultsOf the 3,999 consecutive subjects included, a final analysis was performed on 359 patients that underwent PCI: 148 with urgent PCI due to ACSand 211 patients with elective PCI. Eighty patients in the ACS-group and 120 patients in the elective-PCI group were treated with TAT, although guidelines also allowed DAT. Of 316 patients treated with oral anticoagulants as a part of combination therapy, 275 were on non-vitamin K antagonist oral anticoagulant (NOAC). Reduced doses of NOAC were used in 74 patients treated with rivaroxaban, 60 patients with dabigatran, and 54 patients with apixaban. The proportion of patients treated with reduced NOAC doses adequately to the guidelines was 29%, 100%, and 33% for rivaroxaban, dabigatran, and apixaban, respectively. Inappropriate low doses of NOACs were used in 71% of subjects on rivaroxaban and 67% on apixaban.ConclusionsIn patients with AF undergoing PCI, NOACs are definitely preferred over vitamin-K antagonists (VKAs) in TAT/DAT, and an aggressive antithrombotic strategy with TAT is frequently chosen even if DAT is permissible by the guidelines. Label adherence of using reduced NOAC dose during combination therapy is not satisfactory for apixaban and rivaroxaban and probably results from too cautious an approach to the known indications for reduced therapy. The study is registered in the database Clinical Trials-NCT04419012.
