Digital readiness for cardiovascular care in high-burden US communities with cardiology workforce constraints

Nat MedPublished Linked national data analysis across US census tracts

Authors' conclusion

These findings provide a national framework for distinguishing communities where digital cardiovascular care may be deployed from those where infrastructure and adoption support may first be needed to enable equitable implementation.

Study context

Population
US census tracts with high cardiometabolic disease burden in counties with no cardiologist or declining per-capita cardiologist supply
Participants
82,999 US census tracts
Comparison
Deployment-priority tracts vs investment-priority tracts
  • Deployment-priority tractsn = 4,765
  • Investment-priority tractsn = 21,752
Outcome
Classification of high-burden tracts in counties with no cardiologist or declining per-capita cardiologist supply

Further findings

Distribution and barriers of investment-priority tracts

Investment-priority tracts were spread across the urban-rural continuum and faced different barriers (adoption versus infrastructure)

Geographic variation in classification

Contrasting classifications frequently occurred among neighboring census tracts within the same metropolitan area

Sensitivity analyses

Findings were broadly consistent across nine additional analyses with varying measures of readiness, workforce access, and classification thresholds
