Patient Care Pathways and Outcomes Following Newly Diagnosed Atrial Fibrillation

Area of Science:

• Cardiology
• Health Services Research

Background:

• Care pathways for atrial fibrillation (AF) are not well understood.
• These pathways may impact guideline-concordant treatment and patient outcomes.

Purpose of the Study:

• To examine care pathways for incident atrial fibrillation (AF) patients.
• To assess the association between electrophysiologist (EP) visits and AF treatment and outcomes.

Main Methods:

• Adult patients with incident AF were identified from a large US claims database (2015-2023).
• Care pathways were analyzed based on treating clinician specialty within one year post-diagnosis.
• Cox regression models evaluated the impact of EP visits on treatment and outcomes.

Main Results:

• 20.6% of 37,370 AF patients had an electrophysiologist (EP) visit.
• Older patients and those with higher CHA2DS2-VASc scores were less likely to see an EP.
• EP visits correlated with increased antiarrhythmic drug and oral anticoagulation use.
• Patients aged 80+ with an EP visit had significantly lower stroke risk.

Conclusions:

• Older patients are less likely to consult electrophysiologists (EPs), but EP care pathways increase guideline-concordant AF treatment.
• Electrophysiology care pathways are linked to better patient outcomes, particularly reducing stroke risk in high-risk individuals.
