About this Data

CMS Timely and Effective Care

Much of the data in this interactive database comes from the Centers for Medicare and Medicaid Services' Timely and Effective Care datasets at the hospital, state and national levels. Long wait times are often signals of overcrowding or staff shortages. Here are the measures we include and CMS' definitions for them:


Average (median) time patients spent in the emergency department before leaving from the visit.


Percentage of patients who left the emergency department before being seen.


Average (median) time patients spent in the emergency department, before they were admitted to the hospital as an inpatient


Average (median) time patients spent in the emergency department, after the doctor decided to admit them as an inpatient before leaving the emergency department for their inpatient room.


Percentage of patients who came to the emergency department with stroke symptoms who received brain scan results within 45 minutes of arrival.

CMS Hospital Inspection Violations

We also use data from CMS' hospital inspection reports. CMS only releases violations cited by government inspectors during reviews prompted by complaints. It does not include violations cited by private accrediting organizations or those found during routine hospital inspections by regulators.

While CMS releases data on all types of hospital violations, we pull out only the violations related to ER care. These include violations relating to not properly assessing and treating patients, inadequate medical and nursing staff and not following ER policies and procedures. It also includes violations of the Emergency Medical Treatment and Active Labor Act (EMTALA), which requires ERs to provide a medical screening examination and treatment to stabilize anyone who comes to the emergency department, regardless of their ability to pay.

Once an inspection is complete, hospitals are given 10 calendar days to respond or dispute a violation. If CMS agrees with the dispute, it may revise the inspection report. CMS updates this dataset quarterly.

Here are the specific types of violations we include in ER Inspector and CMS' definitions for them:


The hospital must meet the emergency needs of patients in accordance with acceptable standards of practice.


If emergency services are provided at the hospital, the hospital must ensure that specific emergency services organization and direction requirements are met.


If emergency services are provided at the hospital, the services must be organized under the direction of a qualified member of the medical staff.


If emergency services are provided at the hospital, the services must be integrated with other departments of the hospital.


If emergency services are provided at the hospital, the policies and procedures governing medical care provided in the emergency service or department are established by and are a continuing responsibility of the medical staff.


The hospital must ensure the emergency services personnel requirements are met.


The emergency services must be supervised by a qualified member of the medical staff.


There must be adequate medical and nursing personnel qualified in emergency care to meet the written emergency procedures and needs anticipated by the facility.

EMTALA related violations:


Policies and Procedures Which Address Anti-Dumping Provisions


Receiving Hospitals Must Report Suspected Incidences of Individuals With An Emergency Medical Condition Transferred in Violation of §489.24(e)


Sign Posting


Maintain Transfer Records for Five Years


On-Call Physicians




Appropriate Medical Screening Examination


Stabilizing Treatment


No Delay in Examination or Treatment in Order to Inquire About Payment Status


Appropriate Transfer


Whistleblower Protections


Recipient Hospital Responsibilities (Nondiscrimination)

CMS Patient Satisfaction

Finally, we also use data from CMS' patient satisfaction survey. This is a national, standardized survey of hospital patients about their experiences during a recent inpatient hospital stay. Here's the measure we include in ER Inspector and CMS' definition of it:


Patients who reported YES, they would definitely recommend the hospital


“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.
