Arrhythmias & electrophysiology
Association between neighborhood household income and inpatient atrial fibrillation outcomes
Authors' 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.
Study context
- Population
- Primary Atrial Fibrillation (AF) hospitalizations, US National Inpatient Sample, 2016–2020
- Exposure
- Highest vs lowest median neighbourhood household income quartile
- Outcome
- In-hospital mortality, discharge to care facility and length of stay (highest vs lowest mNHI quartile)
Methodological detailsweighted multivariable logistic and linear regression
- Weighted multivariable logistic and linear regression
