Iowa rural health plan
Iowa's Rural Health Transformation Program. Supports rural hospitals and partners, build collaborations, recruit providers, prevent and treat chronic disease, combat cancer, and rural technology upgrades.
Initiatives, as the state's abstract names them (page 24):
- Hometown Connections
- Best and Brightest
- Combat Cancer-Prevent and Treat
- Communities of Care
- Health Information Exchange
- EMS Community Care Mobile
CMS says the abstract budgets are illustrative and are not award amounts, so none are shown.

About this data
County rates are CDC PLACES model-based estimates of adults, built from the CDC BRFSS survey and Census population data. State and US figures are BRFSS survey results for the same year. They are not averages of counties, and small differences may not be meaningful.
Shortage rows are HRSA designations with status Designated. Scores run from 0 to 25 (0 to 26 for dental); a higher score means greater need. Hospitals are acute care and critical accesshospitals CMS lists in the county, with 30-day rates of unplanned readmission. Health centers are active HRSA-funded and look-alike sites.
Rural health plan initiatives are copied as the state wrote them. Nothing here is medical advice.
