Most patients lack early follow-up care after heart failure hospitalization

A study of over 30,000 Medicare beneficiaries found that fewer than 40% received follow-up care within seven days of discharge. Patients with consistent follow-up were 15% less likely to be readmitted within 30 days. Implementing a simple follow-up system can prevent readmissions and improve patient outcomes.
