Guidance

This eCQM is an episode-based measure and should be reported for each instance of an ED encounter during the measurement period for patients with a STEMI.

This version of the eCQM uses QDM version 5.6. Please refer to the QDM page for more information on the QDM.

Initial Population

All emergency department encounters for patients 18 years and older at the start of the encounter with a diagnosis of ST-segment elevation myocardial infarction (STEMI) during an Emergency Department encounter that ends during the measurement period
