Brief Summary

Atrial fibrillation (AF) is a major public health problem: it impairs quality of life and independently heightens the risks of ischemic stroke, heart failure and all-cause mortality. AF is a common reason for presenting to emergency departments (ED) in Kaiser Permanente Northern California (KPNC) and is associated with frequent hospitalization. Additionally, inter-facility hospitalization rates for AF vary across KPNC. Improvements in modifiable components of ED AF care could potentially reduce low-yield hospitalizations and the associated costs, patient inconveniences, and complications that can ensue. Real-time clinical decision support systems (CDSS) can transform entrenched physician practices and improve patient outcomes. The investigators will conduct a stepped-wedge cluster randomized trial of a CDSS intervention across 13 KPNC EDs for the comprehensive management of acute AF with the following three aims: 1) To evaluate the impact of the CDSS intervention on index hospitalization rates; 2) To evaluate the impact of the CDSS intervention on ED AF rate and rhythm control process-of-care metrics; and 3) To evaluate the impact of the CDSS intervention on AF stroke prevention actions for eligible participants at the time of ED discharge. The investigators hypothesize that the CDSS intervention will safely reduce index hospitalization rates, improve rate and rhythm control process-of-care metrics, and increase stroke prevention actions for eligible participants at ED discharge and within 30 days.

Outcome Measures

Primary Outcomes (3)

  • Number of patients who were hospitalized

    Through emergency department visit, an average of 8 hours

  • Number of patients who received sustained rate-reduction medications

    Through emergency department visit, an average of 8 hours

  • Number of patients who received stroke prevention interventions

    Through emergency department visit, an average of 8 hours

Interventions

Managing atrial fibrillation (AF) patients in the emergency department (ED) is complex, often requiring many separate decisions: How to best reduce the heart rate? Should emergency physicians attempt cardioversion? If so, how? Does this patient need stroke prevention? The investigators' CDSS provides emergency physicians with a one-stop, evidence-based resource that addresses all aspects of ED AF management.

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adult patients presenting to KPNC emergency departments with eligibility criteria

You may qualify if:

  • Adult (≥18y) KPNC members presenting to the ED with a primary ED diagnosis of atrial fibrillation/flutter (AF/FL). Subjects who meet criteria will be identified electronically within the CDSS tool in the electronic health record.

You may not qualify if:

  • Children (\<18y).
  • Non-members of KPNC.
  • Patients who were prisoners, pregnant, receiving hospice or palliative care, or who left against medical advice at the index encounter for AF/FL.
