ABSTRACT

BACKGROUND: Few studies have examined the impact of neighborhood-level factors on outcomes for patients with heart failure with reduced ejection fraction (HFrEF).

OBJECTIVES: The purpose of this study was to understand the impact of neighborhood factors on readmission and mortality risk hospitalized patients with HFrEF.

METHODS: We analyzed data from the Hopeful Heart Trial that evaluated the impact of blended collaborative care for treating HFrEF and depression among patients discharged from 8 Pittsburgh-area hospitals from March 2014 to October 2017. Using patients’ home address at discharge to determine neighborhood Walk Score (WS; 0-100 scale) and Area Deprivation Index (ADI; 0-100), we examined the incidence of 12-month all-cause and cardiovascular-related hospital readmissions and vital status up to 5 years postdischarge through June 2022 using multivariable-adjusted Cox proportional hazards models.

RESULTS: Hopeful Heart enrolled 756 people with HFrEF (baseline mean age 64.0, 44% female, 73% White race, 28% ± 9.1% mean left ventricular ejection fraction, mean 9-Item Patient Health Questionnaire score 12 ± 5.7, median WS 69 (IQR: 49-88), and median ADI 12 (IQR: 10-15) and followed them for a median of 57.7 months (IQR: 25.0-68.4). Individuals from the least walkable neighborhoods experienced greater 12-month all-cause mortality (HR: 1.70 [95% CI: 1.11-2.61]; P = 0.016), while those from the most deprived neighborhoods had higher 12-month cardiovascular-related hospital readmission (HR: 1.39 [95% CI: 1.09-1.78]; P = 0.008). Neither WS nor ADI predicted 12-month all-cause readmission and cardiovascular-related mortality or 5-year all-cause mortality.

CONCLUSIONS: Among recently hospitalized HFrEF patients, neighborhood factors affect 12-month rehospitalization and mortality risk but not 5-year mortality. (Blended Collaborative Care for Heart Failure and Co-Morbid Depression; NCT02044211).
