Description

This measure is used to assess the median time (in minutes) from emergency department (ED) arrival to time of transfer to another facility for acute coronary intervention in acute myocardial infarction (AMI) patients 18 years and older.

Rationale

The early use of primary angioplasty in patients with ST-segment elevation myocardial infarction (STEMI) results in a significant reduction in mortality and morbidity. The earlier primary coronary intervention is provided, the more effective it is (Brodie et al., 1998; DeLuca et al., 2004). National guidelines recommend the prompt initiation of percutaneous coronary intervention (PCI) in patients presenting with STEMI (Antman et al., 2008). Patients transferred for primary PCI rarely meet recommended guidelines for door-to-balloon time of 90 minutes or less (Krumholz et al., 2008).

Extent of Measure Testing

This measure is being collected by hospitals paid under the Outpatient Prospective Payment System; about 4,000 hospitals across the nation. The measure has been collected since April 1, 2008. In 2014, validity testing of critical data elements was performed on this measure for the measure period of April 1, 2014 – March 31, 2015.
