About the National Data
Baseline: 19.2 percent of persons had an emergency department wait time exceeding that recommended for any category in 2016
Target: 12.0 percent
Percentage point improvement
A hospital emergency room visit in which the wait time to see an emergency department clinician (medical doctor, doctor of osteopathy, physician assistant or nurse practitioner) exceeds the recommended wait time is determined by comparing the elapsed time from arrival to being seen to the recommended time frame based on the triage level noted. Recommended times:
- Triage level 1 – immediate is defined as less than one minute,
- level 2 – emergent is defined as 1 – 14 minutes,
- level 3 – urgent is defined as 15 – 60 minutes,
- level 4 – semiurgent is defined as 61 – 120 minutes, and
- level 5 – nonurgent is defined as more than 2 hours – 24 hours.
