Comments

Median time is in minutes from arrival to initiation of a thrombolytic agent in patients with ST segment elevation or left bundle branch block (LBBB) on the electrocardiogram (ECG) performed closest to hospital arrival time.

Effective October 2003, CMS revised this measure and re-titled it "Mean Time to Thrombolysis." NHQR 2005 tables and discussion refer to the prior version of the measure.

ICD-9-CM codes for AMI include 410.01, 410.11, 410.21, 410.31, 410.41, 410.51, 410.61, 410.71, 410.81, and 410.91. The measure specifies exclusion of patients less than 18 years of age and patients transferred from another acute care hospital, including another emergency department. Further information on this and other heart disease measures is available at http://www.cms.hhs.gov/QualityInitiativesGenInfo/.

Median time to PTCA. Median time from arrival to percutaneous transluminal angioplasty (PTCA) in patients with ST segment elevation or left bundle branch block (LBBB) on the electrocardiogram (ECG) performed closest to hospital arrival time. Percent of AMI patients given smoking cessation counseling while hospitalized.
