Description

This measure is used to assess the time (in minutes) from emergency department (ED) arrival to electrocardiogram (ECG) (performed in the ED prior to transfer) for patients 18 years and older with acute myocardial infarction (AMI) or chest pain.

Rationale

Guidelines recommend patients presenting with chest discomfort or symptoms suggestive of ST-segment elevation myocardial infarction (STEMI) have a 12-lead electrocardiogram (ECG) performed within a target of 10 minutes of emergency department (ED) arrival (Krumholz et al., 2008). Evidence supports reperfusion benefits patients with identified STEMI (Antman et al., 2008). The diagnosis and management of STEMI patients is dependent upon practices within the ED. Timely ECGs assist in identifying STEMI patients and impact the choice of reperfusion strategy (Peacock et al., 2007). This measure will identify the median time to ECG for chest pain or acute myocardial infarction (AMI) patients and potential opportunities for improvement to decrease the median time to ECG.

  • Patients discharged/transferred to a short-term general hospital for inpatient care, or to a federal healthcare facility, and
  • An International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) Principal Diagnosis Code for acute myocardial infarction (AMI) (as defined in Appendix A, OP Table 1.1 of the original measure documentation) or an ICD-10-CM Other Diagnosis Codes for angina, acute coronary syndrome, or chest pain (as defined in Appendix A, OP Table 1.1a of the original measure documentation), and
  • Patients receiving an Electrocardiogram (ECG) (as defined in the Data Dictionary)

See the related "Denominator Inclusions/Exclusions" field.

Numerator Description

Continuous variable statement: Time (in minutes) from emergency department (ED) arrival to electrocardiogram (ECG) (performed in the ED prior to transfer) for acute myocardial infarction (AMI) or chest pain patients (with Probable Cardiac Chest Pain as defined in the Data Dictionary) (see the related "Numerator Inclusions/Exclusions" field)

Type of Evidence Supporting the Criterion of Quality for the Measure

  • A clinical practice guideline or other peer-reviewed synthesis of the clinical research evidence

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 January 1, 2012 to December 31, 2012.
