Stroke Prophylaxis for Atrial Fibrillation? To Prescribe or Not to Prescribe-A Qualitative Study on the Decisionmaking Process of Emergency Department Providers.

ABSTRACT: STUDY OBJECTIVE:Although clinical guidelines recommend oral anticoagulation for atrial fibrillation patients at high risk of stroke, emergency physicians inconsistently prescribe it to patients with newly diagnosed atrial fibrillation. We interview emergency physicians to gain insight into themes influencing prescribing of oral anticoagulation for patients discharged from the ED with new-onset atrial fibrillation. METHODS:From September 2015 to January 2017, we conducted semistructured qualitative interviews with a purposeful sampling of 18 ED attending physicians who had evaluated a patient with new-onset atrial fibrillation within the past 30 days. Interview prompts examined physicians' attitudes toward prescription of oral anticoagulation therapy and current clinical guidelines. We used a constructivist grounded theory approach to analyze data and develop a theory on prescribing practices among emergency physicians. RESULTS:Three broad domains emerged from our analyses. (1) Oral anticoagulation prescribing practice: underlying themes affecting oral anticoagulation prescribing from the ED included physician practice patterns, beliefs, and barriers (including experience, comfort, and insurance coverage), and patient factors (including comorbidities, bleeding risk, and social concerns). Ultimately, these themes indicated physician discomfort and a sense of futility in prescribing oral anticoagulation for atrial fibrillation. (2) Guideline usage for oral anticoagulation prescribing: regardless of experience, most emergency physicians did not report using clinical guidelines when treating patients. (3) Recommendations for improved prescribing: physicians recommended the development of a validated, reliable, simple, accessible, and population-specific guideline that considers patient social factors. CONCLUSION:The decision to prescribe oral anticoagulation in the ED is complex. Improving guideline adherence will require a multifaceted approach inclusive of system-level improvements, physician education, and the development of ED-specific tools and guidelines.

Project description:ObjectivesMany interventions have been developed over the years to offer frequent users of the emergency department (FUEDs) better access to quality coordinated healthcare. Despite recognising the role primary care physicians (PCPs) play in FUEDs' care, to date their perceptions of case management, the most studied intervention, have rarely been assessed. Furthermore, a gap regarding PCPs' experience of caring for FUEDs persists. Thus, this study aimed to explore PCPs' perceptions of the care provided to FUEDs in emergency and primary care settings, their views on the local case management team (CMT), and their suggestions to improve FUEDs' care.DesignQualitative study using in-depth semistructured interviews and inductive thematic analysis.SettingCanton of Vaud, Switzerland.ParticipantsThirty PCPs participated, 16 in private practice (PP-PCPs) and 14 based at the Lausanne University Centre of General Medicine and Public Health (Unisanté-U-PCPs).ResultsU-PCPs and PP-PCPs thought that most FUEDs' emergency department (ED) visits were legitimate, but questioned ED adequacy to meet FUEDs' needs. Yet, both PCP groups reported encountering many challenges in FUEDs' care themselves. In this context, PP-PCPs seemed more satisfied of the care they provided to FUEDs than U-PCPs. Generally, U-PCPs seemed to find more value in the CMT to help them care for FUEDs than PP-PCPs. To enhance FUEDs' care, U-PCPs and PP-PCPs suggested enhancing collaboration with other healthcare providers. U-PCPs also wished to increase their availability, and some PP-PCPs considered outpatient clinics, larger group practices or medical centres most appropriate to handle FUEDs' needs.ConclusionsThis study highlights the many challenges PCPs face in caring for FUEDs, that a CM intervention has the potential to mitigate, and provides ways forward in improving FUEDs' care, including reinforced communication with the CMT and ED physicians, and structural changes to their own way of delivering care to FUEDs.

Project description:Background and objectsFew studies focus on multimorbidity and polypharmacy in Chinese atrial fibrillation (AF) patients. We examined the impact of multimorbidity, polypharmacy, and treatment strategies on outcomes in Chinese emergency department (ED)AF patients. We also assessed factors associated with vitamin K antagonist (VKA) non-use in AF patients with multimorbidity or polypharmacy.Methods2015 AF patients who presented to emergency department (ED) were enrolled from Nov 2008 to Oct 2011, mean follow-up of 12-months. Cox regressions were performed to identify the impact of multimorbidity and polypharmacy on clinical outcomes.ResultsSix hundred and sixty-five patients in low morbidity group (≤1 comorbidity), 608 patients in moderate morbidity group (2 comorbidities), 742 patients in high morbidity group (≥3 comorbidities). Five hundred and seventy patients (28.3%) had polypharmacy (≥5 medications). High and moderate morbidity groups were significantly associated with a higher risk of all-cause death (HR 2.083, 95%CI 1.482-2.929; HR 1.713, 95%CI 1.198-2.449), CV death (HR 2.457, 95%CI 1.526-3.954; HR 1.974, 95%CI 1.206-3.232) and major bleeding (HR 4.126, 95%CI 1.022-16.664; HR 6.142, 95%CI 1.6789-22.369) compared with low morbidity group. In VKA subgroup, only high morbidity group was associated with a higher risk of all-cause death (HR 2.521, 95%CI 1.482-2.929), but not significantly in other events. For polypharmacy category, there were no significant statistics among these endpoints. Coronary artery disease (CAD), hypertension, chronic obstructive pulmonary disease, and antiplatelet therapy were independent predictors for VKA non-use in whole cohort, and patients with multimorbidity. CAD and antiplatelet therapy were independent predictors for VKA non-use in patients with polypharmacy.ConclusionMultimorbidity was associated with worse outcomes in Chinese ED AF patients. Polypharmacy showed no significant statistics among these outcomes. CAD and antiplatelet therapy were independent risk factors of VKA non-use in Chinese ED AF patients with multimorbidity or polypharmacy.

Project description:STUDY OBJECTIVE:In the United States, nearly 70% of emergency department (ED) visits for atrial fibrillation result in hospitalization. The incidence of serious 30-day adverse events after an ED evaluation for atrial fibrillation remains low. This study's goal was to prospectively validate our previously reported Risk Estimator Decision Aid for Atrial Fibrillation (RED-AF) model for estimating a patient's risk of experiencing a 30-day adverse event. METHODS:This was a prospective cohort study, which enrolled a convenience sample of ED patients presenting with atrial fibrillation. RED-AF, previously derived from a retrospective cohort of 832 patients, assigns points according to age, sex, coexisting disease (eg, heart failure, hypertension, chronic obstructive pulmonary disease), smoking, home medications (eg, ?-blocker, diuretic), physical examination findings (eg, dyspnea, palpitations, peripheral edema), and adequacy of ED ventricular rate control. Primary outcome was occurrence of greater than or equal to 1 atrial fibrillation-related adverse outcome (ED visits, rehospitalization, cardiovascular complications, death) within 30 days. We identified a clinically relevant threshold and measured RED-AF's performance in this prospective cohort, assessing its calibration, discrimination, and diagnostic accuracy. RESULTS:The study enrolled 497 patients between June 2010 and February 2013. Of these, 120 (24%) had greater than or equal to 1 adverse event within 30 days. A RED-AF score of 87 was identified as an optimal threshold, resulting in sensitivity and specificity of 96% (95% confidence interval [CI] 91% to 98%) and 19% (95% CI 15% to 23%), respectively. Positive and negative predictive values were 27% (95% CI 23% to 32%) and 93% (95% CI 85% to 97%), respectively. The c statistic for RED-AF was 0.65 (95% CI 0.59 to 0.71). CONCLUSION:In this separate validation cohort, RED-AF performed moderately well and similar to the original derivation cohort for identifying the risk of short-term atrial fibrillation-related adverse events in ED patients receiving a diagnosis of atrial fibrillation.
