The US has no single nationwide wait feed. Every state, health system, and urgent care chain publishes differently. ERClock layers them: HCA's national feed, LifePoint, Trinity Health and Sutter via Epic MyChart, Prime Healthcare, Stanford, UCSD, MarinHealth, Clockwise.MD, Cleveland Clinic FHIR, and more. The CMS Hospital General Information directory fills the gaps so every Medicare-certified ER appears, even when no live data is published.
We aggregate publicly published wait times from US health systems and hospitals, joined with the federal CMS Hospital General Information directory.
Live wait time JSON / HTML widgets published by HCA Healthcare, LifePoint, Trinity Health, Sutter Health, Prime Healthcare, Stanford, UC San Diego, Hackensack Meridian, Mount Sinai, Houston Methodist, and many more.
Every Medicare-certified hospital with an emergency department in the US, sourced from the CMS "Hospital General Information" dataset, refreshed quarterly. Includes addresses, phone, ownership, and CMS overall star rating.

Wait times are estimates and can change rapidly. Different hospitals report different metrics. This is not medical advice. Always call 911 in an emergency. Read our methodology.
