Indicator Description and Calculation
DescriptionThis indicator measures the time interval between the earlier of Triage Date/Time or Registration Date/Time and the Disposition Date/Time (as determined by the main service provider).
Calculation: Description

The indicator is measured in hours, usually using the 90th percentile and/or 50th percentile, which represents the maximum length of time that 90% and/or 50% of patients stay in the emergency department (ED) until a visit disposition decision is made.

Unit of analysis: Single ED visit

Description:
All emergency visits
Inclusions:
1. Unscheduled emergency visits

2. ED visits with a valid and known Registration Date/Time or Triage Date/Time and a valid and known Disposition Date/Time

Exclusions:
1. Scheduled emergency visits

2. ED visit with Visit Disposition 02 (Left without being seen, not triaged)

3. Both Registration and Triage Date/Time are invalid/unknown, or physician Disposition Date/Time is invalid/unknown

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 time 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 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 spend in the ED until a visit disposition decision is made.

A small number is desirable for this indicator.

Caveats and Limitations

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.

For more information on NACRS coverage, please see the NACRS Quick Stats: http://www.cihi.ca/CIHI-ext-portal/internet/EN/Quick_Stats/quick+stats/quick_stats_main?xQSType=Pre-formatted%20Table&xTopic=Hospital%20Care&pageNumber=2&resultCount=10&filterTypeBy=1&filterTopicBy=5&autorefresh=1.

Comments

Depending on the acuity of the case or hospital procedures, triage may occur before registration or vice versa. Therefore, the earlier of these 2 events is used as the starting point for this indicator's calculation.
