Beacon Hospital, a 480-bed system in the Midwest, faced the same challenge as every health system in America: congestive heart failure (CHF) readmissions were eating margin and hurting outcomes.
The intervention
Every CHF patient discharged in the pilot cohort received a scheduled series of voice check-ins over 30 days — covering symptoms, medication adherence, weight tracking, and follow-up appointment coordination.
The results
- 22% reduction in 30-day readmissions
- 4.8/5 patient satisfaction score
- 41% of red-flag symptoms caught before an ER visit
- $3.1M avoided cost in year one
What made it work
Three things: physician-designed conversation flows, warm hand-off to a nurse case manager on any red flag, and tight integration with the EHR so notes flowed back automatically.
