Guidance

This measure specification defines how to determine the duration of an individual Emergency Department encounter. Reporting requires the median of all ED encounter durations defined as [Encounter: encounter ED] facility location departure date and time minus [Encounter: encounter ED] ED facility location arrival date and time.

Calculate the ED time in minutes for each patient in the measure population; report the median time for all calculations performed. The specification provides elements from the clinical electronic record required to calculate for each ED encounter, i.e., the length of time the patient was in the Emergency Department, also stated as: the Datetime difference between the Emergency Department facility location departure datetime and the Emergency Department facility location arrival datetime. The calculation requires the median across all ED encounter durations.

For each population, results should be reported without stratification and then with each stratum applied. For this measure, the number of encounters that fall into the Initial Population are reported without stratification, then reported according to the defined stratification. The number of encounters that fall into the Measure Population are reported without stratification, then reported according to the defined stratification. The computed continuous variable defined by the Measure Observation is reported for the Measure Population also, then reported according to the defined stratification.
