Measures of social deprivation and outcomes after percutaneous coronary intervention

Background Disparities in socioeconomic status are a frequently cited factor associated with worse cardiovascular outcomes. The social deprivation index (SDI) can be used to quantify socioeconomic resources at the population level. Objectives The aim of this study was to assess the association of SDI with clinical outcomes following percutaneous coronary interventions (PCI). Methods This was a retrospective observational analysis of patients who underwent PCI and were included in a multicenter cardiac catheterization registry study. Baseline characteristics, congestive heart failure (CHF) readmission rates and survival were compared between patients with the highest and lower SDI. SDI was calculated based on the US community survey census tract‐level data. Results Patients within the highest SDI quintile (n = 1843) had more comorbidities and a higher risk of death [hazard ratio (HR): 1.22 (95% confidence interval, CI: 1.1–1.39, p = 0.004); log rank: p = 0.009] and CHF readmission [HR: 1.56 (1.39–1.75, p
