Abstract
Purpose
This study examined how certain aspects of residential neighborhood conditions (ie,
observed built environment, census-based area-level poverty, and perceived disorder)
affect readmission in urban patients with heart failure.
Methods
A total of 400 patients with heart failure who were discharged alive from an urban-university
teaching hospital were enrolled. Data were collected about readmissions during a 2-year
follow-up. The impact of residential neighborhood conditions on readmissions was examined
with adjustment for 7 blocks of covariates: 1) patient demographic characteristics;
2) comorbidities; 3) clinical characteristics; 4) depression; 5) perceived stress;
6) health behaviors; and 7) hospitalization characteristics.
Results
A total of 83.3% of participants were readmitted. Participants from high-poverty census
tracts (≥20%) were at increased risk of readmission compared with those from census
tracts with <10% poverty (hazard ratio [HR]: 1.53; 95% confidence interval: 1.03-2.27;
P < .05) when adjusted for demographic characteristics. None of the built environmental
or perceived neighborhood conditions were associated with the risk of readmission.
The poverty-related risk of readmission was reduced to nonsignificance after including
diabetes (HR: 1.33) and hypertension (HR: 1.35) in the models.
Conclusions
The effect of high poverty is partly explained by high rates of hypertension and diabetes
in these areas. Improving diabetes and blood pressure control or structural aspects
of impoverished areas may help reduce hospital readmissions.
