Summary:

Rhythm control procedures are selectively applied and vary by demographic and clinical factors, according to a retrospective cross-sectional study of patients in Auckland with atrial fibrillation or flutter. A total of 1908 patients (46.8% female) were identified up to 31 August 2021, of whom 15.3% underwent rhythm control procedures. Increased age and female sex were associated with a lower chance of receiving rhythm control procedures (adjusted OR per year 0.96 [95% CI 0.95-0.97] and 0.46 [95% CI 0.34-0.63], respectively). Compared with European patients, Māori, Pacific peoples and patients of other ethnicities were less likely to undergo rhythm control procedures (aOR 0.52 [95% CI 0.36-0.77], 0.41 [95% CI 0.28-0.60] and 0.47 [95% CI 0.28-0.79], respectively).

Comment:
Further evidence demonstrating inequities in cardiovascular care in Aotearoa. Even after adjustment for clinical factors, Māori, Pacific peoples and women were significantly less likely to receive rhythm control procedures for atrial fibrillation/flutter. The priority is to understand the mechanisms underlying these disparities, particularly across referral pathways and shared decision making, so that interventions can address rather than just document them.
