Social determinants of health and catheter ablation after an incident diagnosis of atrial fibrillation: a Danish nationwide cohort study
Authors' conclusion
In the Danish universal healthcare system, patients with AF who had lower educational attainment, lower family income, or were living alone were less likely to undergo AF ablation.
Study context
- Population
- Patients with incident hospital diagnosis of atrial fibrillation (AF), Denmark, 2005–2018122,276 men
- Exposure
- Lower or medium vs higher education, lower or medium vs higher family income, living alone (social determinants of health (SDOH)) and AF ablation
- Outcome
- Catheter ablation for AF
Methodological detailssex-specific analyses, age-adjusted cause-specific proportional hazard models
- Sex-specific analyses
- Age-adjusted cause-specific proportional hazard models
