ABSTRACT
BACKGROUND:
The impact of socioeconomic status on the clinical outcomes of patients admitted to the hospital for atrial fibrillation (AF) is not well described.OBJECTIVE:
The purpose of this study was to determine the association between median neighborhood household income (mNHI) and clinical outcomes among patients admitted to the hospital for AF.METHODS:
We retrospectively analyzed primary AF hospitalizations from the United States National Inpatient Sample between 2016 and 2020. The analyzed sample was divided into quartiles based on the mNHI in the zip code of the patient's residence. The lowest quartile was used as the reference category. Study outcomes included inpatient procedure utilization (ablation, cardioversion, percutaneous left atrial appendage closure), length of stay, cost, mortality, and disposition. Weighted multivariable logistic and linear regression, adjusting for multiple patient and hospital-level characteristics, was performed.RESULTS:
Patients in the highest mNHI quartile had lower comorbidity burden, lower in-hospital mortality (odds ratio [OR] 0.78; 95% confidence interval [CI] 0.7-0.87; P <.001), lower discharges to care facility (OR 0.86; 95% CI 0.83-0.9; P <.001), shorter length of stay (adjusted mean difference -0.26; 95% CI -0.30 to -0.22; P <.001), higher procedure utilization, and higher health care costs ($12,124 vs $10,018) compared to the lowest mNHI quartile patients.CONCLUSION:
We identified significantly higher in-hospital mortality and lower procedural/resource utilization in patients living in lower-income neighborhoods compared to higher-income neighborhoods. Further research is needed to better understand the drivers of these disparities and the strategies to improve health care disparities between socioeconomic groups.Key words
