Neighborhood Socioeconomic Status and Heart Failure or All-Cause Readmission Within a Municipal Hospital System
- retrospective electronic medical record-based cohort study
Authors' conclusion
Lower nSES is associated with higher HF-specific and all-cause readmission within a municipal hospital system. Future research should focus on improving HF morbidity for readmission "hotspot" neighborhoods.
Study context
- Population
- Adults with International Classification of Diseases-9 or −10 diagnosis of heart failure (HF), geocoded residential address, and index HF admission within a municipal public health system between January 2001 and September 2019
- Participants
- 2,440 adults
- Exposure
- lowest neighborhood socioeconomic status (nSES) quintile vs highest nSES quintile
Main finding
HF readmission · 1 year
Hazard ratio
1.62
95% CI 1.09–2.41
P = 0.018
lowest nSES quintile vs highest nSES quintile
HR 1.62 (95% CI 1.09–2.41); P = 0.018
As reported in the abstract
Observational data: associations, not effects.
Further findings
| Outcome | HR (95% CI) | P value | |
|---|---|---|---|
| All-cause readmission · 1 year · 54% higher all-cause readmission risk | 1.54 (1.17–2.02) | P = 0.002 | |
| 0.512Hazard ratio (log scale) |
All-cause mortality
- nSES was not associated with all-cause mortality
Baseline characteristics
- median age
- 60.8 years (SD 14.8 years)
- females
- 33.6% (821/2,440)
- self-identified as Black
- 35.7% (870/2,440)
- median follow-up time
- 38.1 months (IQR: 16.2-74.1 months)
Geographic hotspots
- Geographic "hotspots" of index HF hospitalizations or all-cause readmissions occurred in neighborhoods disproportionately affected by historical redlining policies and single-room occupancy units
