Abstract 130: Social Factors Influence Readmission Rates in Women with Acute Myocardial Infarction

Abstract

Background: Studies have shown that women with acute myocardial infarction (AMI) have a higher prevalence of unfavorable social variables than men and have a worse outcome. Less is known regarding the impact of these social variables on 30-day all-cause readmission after AMI. Methods: We analyzed adult patients with AMI enrolled in a Quality Improvement Program aimed to decrease 30-day all-cause readmission after AMI. We compared clinical and social variables by sex using Pearson Chi Squared and Cramer’s V test. Multivariate linear regression was used to measure adjusted odds for 30-day all-cause readmission by sex. Results: Among 173 patients included in our project, 54 (31.2%) were women. Table 1 depicts the clinical and social variables in women and men. Only 33.3% of women were married or had domestic partner and less than one fourth were employed. Nearly half of women needed help at home, and nearly half of women did not speak English as their first language. These variables were significantly different by sex. The 30-day all-cause readmission was higher in women than men (20.4% vs 7.6%, p=0.03). After adjusting for clinical and social variables this difference by sex in 30-day all-cause readmission was no longer noted (OR 1.1, 95% CI 0.33-3.74, p=0.86). Conclusion: Women with AMI are more likely than men to have unfavorable social factors that can impact recovery from AMI, and women have a higher 30-day all-cause readmission rate. The higher readmission rate in women appears to be influenced by these social factors. Healthcare interventions aimed at reducing 30-day all-cause readmission after AMI should focus on providing assistance for those requiring additional social support at home.
