Introduction: Shared decision-making (SDM) about anticoagulant treatment in patients with atrial fibrillation (AF) is widely recommended but its effectiveness is unclear. We assessed the extent to which using an SDM tool promotes high-quality SDM. Hypothesis: SDM will improve communication quality, knowledge, and decisional conflict and will translate to improved medication adherence and outcomes. Methods: In this multicentre encounter-randomized trial, we included patients with nonvalvular AF considering starting/reviewing anticoagulation, and their clinicians. We compared usual care with or without ANTICOAGULATION CHOICE, an SDM conversation tool for use during the clinical encounter that presents individualized risk estimates and compares anticoagulation options across patient important issues. Results: We enrolled and video-recorded 922 patient-clinician encounters. So far, our data have shown that participants in both arms reported near-optimal communication quality, knowledge, and decisional conflict (JAMA IM-2020). Patients in intervention-arm estimated their stroke risks more accurately and were more involved in decision-making (JAMA IM-2020), clinicians were more satisfied (JAMA IM-2020), and cost conversation were more common (JAMA NO-2021). Use of the intervention had no effect on treatment decisions, encounter duration (JAMA IM-2020), treatment adherence, clinical outcomes (JAHA-epub) or patient-perceived sense of the care plan (PEC-epub). New analyses have shown that compared to eligible white participants, black participants more frequently did not enrol to the study. Enrolment of Black, indigenous, and people of colour benefited most form including and prioritizing practices most likely to care for them. We found no evidence of contamination (tool use, functional, or learned) between study arms. Conclusions: Use of an SDM tool improved some measures of SDM quality, without affecting treatment decisions and their sensibility, encounter duration, patient adherence, or clinical outcomes. Our results should calibrate expectations as to what could be accomplished by implementing SDM tools about anticoagulation in the care of patients with AF
Enrolling People of Color to Evaluate a Practice Intervention: Lessons from the Shared Decision-Making for Atrial Fibrillation (SDM4AFib) Trial
Abstract Background: Trial recruitment of Black, indigenous, and people of color (BIPOC) is key for interventions that interact with socioeconomic factors and cultural norms, preferences, and values. We report on our experience enrolling BIPOC participants into a multicenter trial of a shared decision-making intervention about anticoagulation to prevent strokes, in patients with atrial fibrillation (AF). Methods: We enrolled patients with AF and their clinicians in 5 healthcare systems (three academic medical centers, an urban/suburban community medical center, and a safety-net inner-city medical center) located in three states (Minnesota, Alabama, and Mississippi) in the United States. Clinical encounters were randomized to usual care with or without a shared decision-making tool about anticoagulation. Analysis: We analyzed BIPOC patient enrollment by site, categorized reasons for non-enrollment, and examined how enrollment of BIPOC patients was promoted across sites.Results: Of 2247 patients assessed, 922 were enrolled of which 147 (16%) were BIPOC patients. In comparison to trial-eligible White participants, eligible Black participants more frequently did not enroll (102 (11%) vs. 185 (15%); p <.001). The rate of BIPOC patients enrollment varied substantially by site and was generally reflective of the population served at each participating site. Enrollment of BIPOC patients benefited most from including and prioritizing practices most likely to care for BIPOC patients, with lower yield from specific efforts to reach BIPOC clinic attendees and enrolling BIPOC patients first when possible. Conclusions: Enrollment from practices that have implemented policies that favor the care of BIPOC patients can contribute to generate trustworthy estimates of the effect of these interventions in clinical practice that are applicable to BIPOC populations. Best practices to optimize the enrollment of BIPOC participants into trials that examined complex and culturally sensitive interventions remain to be developed.Clinical trial registration: ClinicalTrials.gov (NCT02905032)
Effect of Shared Decision‐Making for Stroke Prevention on Treatment Adherence and Safety Outcomes in Patients With Atrial Fibrillation: A Randomized Clinical Trial
Background Guidelines promote shared decision‐making (SDM) for anticoagulation in patients with atrial fibrillation. We recently showed that adding a within‐encounter SDM tool to usual care (UC) increases patient involvement in decision‐making and clinician satisfaction, without affecting encounter length. We aimed to estimate the extent to which use of an SDM tool changed adherence to the decided care plan and clinical safety end points. Methods and Results We conducted a multicenter, encounter‐level, randomized trial assessing the efficacy of UC with versus without an SDM conversation tool for use during the clinical encounter (Anticoagulation Choice) in patients with nonvalvular atrial fibrillation considering starting or reviewing anticoagulation treatment. We conducted a chart and pharmacy review, blinded to randomization status, at 10 months after enrollment to assess primary adherence (proportion of patients who were prescribed an anticoagulant who filled their first prescription) and secondary adherence (estimated using the proportion of days for which treatment was supplied and filled for direct oral anticoagulant, and as time in therapeutic range for warfarin). We also noted any strokes, transient ischemic attacks, major bleeding, or deaths as safety end points. We enrolled 922 evaluable patient encounters (Anticoagulation Choice=463, and UC=459), of which 814 (88%) had pharmacy and clinical follow‐up. We found no differences between arms in either primary adherence (78% of patients in the SDM arm filled their first prescription versus 81% in UC arm) or secondary adherence to anticoagulation (percentage days covered of the direct oral anticoagulant was 74.1% in SDM versus 71.6% in UC; time in therapeutic range for warfarin was 66.6% in SDM versus 64.4% in UC). Safety outcomes, mostly bleeds, occurred in 13% of participants in the SDM arm and 14% in the UC arm. Conclusions In this large, randomized trial comparing UC with a tool to promote SDM against UC alone, we found no significant differences between arms in primary or secondary adherence to anticoagulation or in clinical safety outcomes.
