Reports that changes to Critical Access Hospitals (CAHs) reimbursement may spur some CAHs to close, with the most financially vulnerable more likely to close. The average resident of these communities would experience an 80% increase in distance to the nearest hospital if the CAH were to close. This analysis considers the communities served by the 93 CAHs with the lowest profitability and therefore most likely to close due to a change in Medicare reimbursement.
