Data Sources: Live wait-time values and recent patient reports are compiled from hospital-published sources, patient submissions, and verified updates. Historical data represents CMS-audited annual performance benchmarks and is not a live estimate of current ER volume. Hospital ownership labels and hospital overall ratings come from the CMS Hospital General Information dataset. CMS ratings are a broad summary, not a perfect measure of whether a hospital is best for a specific service.
