Description:
All emergency visits
Inclusions:
1. Admitted unscheduled emergency visits

2. ED visits with a valid and known registration date/time or triage date/time and a valid and known date/time the patient left the ED
Exclusions:
1. Scheduled emergency visits

2. Non-admitted unscheduled emergency visits

3. Visits with both unknown/invalid registration and triage date/time OR with unknown/invalid patient left ED date/time

Background, Interpretation and Benchmarks
Rationale

Time is crucial to the effectiveness and outcome of patient care, especially for emergency patients. In conjunction with other indicators, this can be used to monitor the total length of time admitted patients spend in the ED in an effort to improve the efficiency and, ultimately, the outcome of patient care.

Multiple factors can influence the indicator results, including availability of inpatient beds, triage level, patient population and hospital resources.

Interpretation

The 90th, 50th or other percentile of this indicator represents the maximum length of time that 90%, 50% or other percentage of patients admitted from the ED spend in the ED.

A small number is desirable.

Scheduled visits to the ED are excluded from this indicator.

This indicator can also be calculated at other percentiles, such as the 10th, 25th or 75th percentile.

Trending Issues

Coverage in the National Ambulatory Care Reporting System (NACRS) changes over time as more jurisdictions participate.
