This document discusses patient re-admissions and strategies to reduce them. It defines a hospital re-admission as an admission within 30 days of discharge from the same or another hospital. Nearly 20% of Medicare hospitalizations result in re-admission within 30 days, with heart failure, myocardial infarction and pneumonia having some of the highest re-admission rates. The Affordable Care Act established the Hospital Readmissions Reduction Program to reduce payments to hospitals with excess re-admissions. Common reasons for re-admission include medication errors and failure to follow up with a physician. Various organizations are working on initiatives to improve care transitions and reduce preventable re-admissions.
