Social Determinants of Health and Disparities in Diagnosis-to-Ablation Time for Atrial Fibrillation
Authors' conclusion
Greater SDOH burden is associated with significant delays in accessing AF ablation.
Study context
- Population
- Patients undergoing first atrial fibrillation (AF) ablation, Hopkins AF Ablation Registry (2014–2023)
- Participants
- 1,025 patients
- Exposure
- Higher vs lower Area Deprivation Index
- Outcome
- AF diagnosis-to-ablation time (DAT) by ADI
Methodological detailsregistry-based
- Registry-based
Main finding
As reported in the abstract
DAT per 10-unit increase in ADI percentile
Increase in diagnosis-to-ablation time (DAT) per 10-unit increase in Area Deprivation Index (ADI) percentile
6.96%
95% CI 1.02–1.12P = 0.003
Delay per 10-unit increase in ADI percentile
3.83 months
95% CI 1.27–6.39
Observational data: associations, not effects.
Further findings
DAT by age group, sex or race (subgroups)
- No significant interactions by age group, sex or race
Anticoagulant prescription at discharge (eligible patients)
- No significant association with ADI percentile
- P = 0.097
