Abstract
Introduction: There is limited data on how psychosocial risk factors (PSRFs) affect the outcomes of patients undergoing atrial fibrillation (AF) ablation. Hypothesis: We hypothesized that the presence of PSRFs affects the outcomes of AF ablation and tested this hypothesis using a nationally representative sample of the US population. Methods: The National Readmissions Database (NRD) was analyzed from 2016-2019 to identify patients ≥ 18 years old undergoing AF ablation. Patients were divided into two cohorts based on the presence or absence of ≥1 PSRF. PSRFs were divided into 5 domains including limited cognitive understanding, substance use, psychiatric disease, low socioeconomic status, and uninsured status. A multivariable logistic regression model was utilized to adjust for confounders. Results: Our cohort included 50,623 AF ablation procedures, of which 21,363 (42.2%) had ≥ 1 PSRF. On multivariable analysis, the presence of ≥ 1 PSRF was associated with higher odds of cardiovascular complications (adjusted odds ratio [aOR] 1.11; 95% confidence interval [CI]: 1.02-1.22; p=0.02), peripheral vascular complications (aOR:1.18; 95% CI: 1.01-1.38; p=0.04), pulmonary complications (aOR:1.16; 95% CI: 1.05-1.29; p<0.01) and neurological complications (aOR:1.42; 95% CI: 1.12-1.78; p<0.01), along with higher odds of 30-day all-cause readmissions (aOR:1.30; 95% CI: 1.19-1.43; p<0.01) and atrial fibrillation/flutter related readmissions (aOR:1.27; 95% CI: 1.08-1.50; p<0.01), 90-day all-cause readmissions (aOR:1.30; 95% CI: 1.20-1.40; p<0.01) and atrial fibrillation/flutter related readmissions (aOR:1.22; 95% CI: 1.06-1.41; p<0.01), and 180-day all-cause readmissions (aOR:1.35; 95% CI: 1.24-1.45; p<0.01) (Figure 1). Conclusion: In conclusion, our data suggest an association between PSRFs and worse in-hospital outcomes along with increased all-cause and arrhythmia-related readmissions in patients undergoing AF ablation.
