Emergency Department Wait Times: Latest Data and How to Reduce Your Wait
Emergency department (ED) wait times are a major concern for patients and hospitals alike. Long waits can delay critical care, increase patient anxiety, and affect overall outcomes. Understanding ED wait time data helps patients make informed decisions about where and when to seek emergency care.
Current Emergency Department Wait Time Statistics
National data from CMS and other sources reveals key patterns in ED wait times:
- Average door-to-doctor time: Patients typically wait between 20 and 40 minutes to see a physician, depending on the hospital and time of visit
- Average total ED visit: The median time from arrival to discharge for patients not admitted ranges from 2 to 4 hours
- Admission wait times: Patients who need to be admitted often wait significantly longer due to hospital bed availability
- Peak hours: Monday mornings and late evenings tend to have the longest wait times at many facilities
CMS Timely Care Measures
CMS tracks several emergency care timeliness measures as part of hospital quality reporting:
- ED-1: Average time from arrival to admission for patients needing inpatient care
- ED-2: Average time from decision to admit to actual admission
- OP-18: Average time from arrival to departure for outpatient ED visits
- OP-20: Average time from arrival to initial evaluation by a qualified medical professional
- OP-22: Left without being seen rate — percentage of patients who leave before evaluation
How to Check ER Wait Times
Before heading to an emergency room, you can often check estimated wait times:
- Compare hospital ED timeliness data on Medicare Care Compare
- Many hospital systems post real-time estimated wait times on their websites
- Some hospitals offer mobile apps with live wait time updates
Tips for Reducing Your Emergency Wait
- Know your options: For non-life-threatening conditions, urgent care centers may offer faster treatment
- Bring medical information: Having your medication list, insurance card, and medical history readily accessible speeds intake
- Understand triage: Patients are seen based on severity, not arrival order — the sickest patients are treated first
- Consider timing: If your condition allows, visiting during off-peak hours may reduce wait times
- Communicate changes: If your condition worsens while waiting, alert the triage nurse immediately
When to Call 911
Always call 911 for potentially life-threatening conditions including chest pain, difficulty breathing, stroke symptoms (sudden numbness, confusion, trouble speaking), severe bleeding, or loss of consciousness. Ambulance patients are evaluated immediately upon arrival.

Important
This article explains how hospital quality data works and is for general information only. It is not medical advice and must not be used to decide whether to seek, delay or refuse care — that is a decision for you and a clinician who knows your situation.
CMS quality measures describe care delivered during earlier reporting periods and are refreshed roughly quarterly. A hospital's staffing, services and performance can change well before the published numbers do.
