Higher social vulnerability was significantly associated with worse geographic access to cardiac rehabilitation facilities, a disparity that intensified in rural communities (P<0.001).

Does higher social vulnerability correlate with worse geographic access to cardiac rehabilitation facilities in US counties?
Higher social vulnerability is significantly associated with worse geographic access to cardiac rehabilitation, particularly in rural US counties, highlighting the need for virtual or hybrid models to reduce barriers.
p-value: p=<0.001
BACKGROUND: There is a dearth of research examining geographic disparities in access to cardiac rehabilitation (CR). We evaluated whether disparities in geographic access to CR exist among socially vulnerable communities, using the Social Vulnerability Index (SVI). METHODS: Among 3113 US counties, we investigated relationships between SVI and number of hospitals with CR per 100 000 adults, modeled with SVI as a linear variable, and SVI and distance to the nearest county with CR facilities, modeled using spline terms for SVI. We used multivariable zero-inflated negative binomial regression modeling adjusted for county population, CR eligibility, percentage without health insurance, metropolitan status, and availability of existing health care infrastructure. We explored whether these relationships changed in the context of rurality. RESULTS: <0.001). CONCLUSION: More socially vulnerable communities experienced worse geographic access to CR facilities. This access disparity intensified in rural communities. Our findings call for reducing barriers to CR access among socially vulnerable and rural communities, potentially through virtual or hybrid models of CR.
Chen et al. (Thu,) conducted a observational in Geographic access to cardiac rehabilitation (n=3,113). Social Vulnerability Index (SVI) was evaluated on Number of hospitals with CR per 100 000 adults and distance to the nearest county with CR facilities (p=<0.001). Higher social vulnerability was significantly associated with worse geographic access to cardiac rehabilitation facilities, a disparity that intensified in rural communities (P<0.001).
