Patient Pathways Through This ER

After a patient arrives at the emergency room, they are typically seen by a doctor or medical practitioner and then either sent home or admitted to the hospital and taken to a room. A small percentage of patients leave without being seen. The chart below shows on average how long each of these pathways take. Lower numbers are better, and all times refer to the average length of time people waited.

Arrives at ER
2% of patients leave without being seen
3hrs 33min Admitted to hospital
4hrs 29min Taken to room
2hrs 4min Sent home

All wait times are average.

Detailed Quality Measures

Here is a more in depth look at each quality measure, compared to state and national averages for hospitals with medium ER volumes. Experts caution that very small differences between hospitals for a given measure are unlikely to correspond to noticeable differences in the real world.

Violations Related to ER Care

Problems found in emergency rooms at this hospital since 2015, as identified during the investigation of a complaint. About This Data →

This hospital has no violations related to ER care since 2015.


“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.

Additional design and development by Mike Tigas and Sisi Wei.


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.
