Notes

“Average time” refers to the median wait time (the midpoint of all patients' wait times). References to “doctor or medical practitioner” indicate a doctor, nurse practitioner or physician's assistant. CMS reports the CT scan quality measure as the percentage of patients who received a scan within 45 minutes. We have reversed that measure so that all measures follow a “lower is better” pattern.

All data comes from the Centers for Medicare and Medicaid Services. Detailed quality measures at the hospital, state and national level were last updated September 2019. Most data was collected between October 2017 and October 2018. Data on ER-related violations is from January 2015 to June 2019.

Don’t See Your ER?

In some cases we aren’t able to identify the exact location of a hospital, so it doesn’t appear on our mapped search results. However, it may still be in our database – try looking for it in the list of hospitals on each state's page.

In other cases, the hospital is missing from our database because it doesn't have an emergency department.

In other cases, the hospital is missing from the federal government’s Centers for Medicare and Medicaid Services (CMS) data. There are a couple of reasons why a hospital isn’t included in CMS data: it may not participate in Medicare, or it may share a certification number with another hospital (common across large hospital systems).

If you notice a hospital missing from our database, please first check if you can find it on CMS' website, and that it is listed as having an ER. If so, please email us with the hospital name and address.
