Article Description

Purpose: The purpose of the study was to examine the relationship between food insecurity, neighborhood disadvantage, and hospital readmission within 90 days of discharge for health system patients. Design: The study used a retrospective, correlational design with a single cohort. Methods: Records of adult patients with a health system primary care provider and discharged from hospital to home were included. Data were obtained from health system billing database, medical record, and publicly available population databases. A time-to-readmission analysis was conducted with a Kaplan-Meier plot, log-rank test, and Cox regression analysis. Results: The final sample included 41 566 records; the rate of food insecurity was 1.45%, and 90-day readmission rate was 16.7%. The mean area deprivation index score was 54.4 (SD, 26.0). After adjusting for patient demographics, comorbidity, and length of stay, food insecurity resulted in 1.94 times higher risk of readmission (hazard ratio, 1.94; 95% confidence interval, 1.69–2.23; P < .001). Neighborhood disadvantage and lower food access were not significant in final models. Conclusions: Food insecurity should be identified and addressed as part of transitional care to improve patient outcomes. Future research should focus on models of care that ensure connection to community resources to resolve food insecurity and evaluate the impact on patient outcomes.
