  QT15 - Turnaround Time (TAT)
  of Troponin

 

 

 

Updated October 27, 2005

Turnaround Time (TAT) of Troponin QT15
The swiftness with which physicians establish diagnoses of acute myocardial infarction (AMI) in patients presenting to the emergency department (ED) with chest pain may determine the type and predict the outcomes of therapy those patients will receive. Included in the total time consumed in establishing diagnoses of AMI are the component intervals required to measure biochemical markers of myocardial injury, one of the most critical of which is troponin.

Monitor Objective
Determine the median order-to-report turnaround time of troponin (I or T) ordered on patients presenting to EDs with signs and symptoms of acute myocardial injury.

Data Collection
Participants will record the TATs (in minutes) for three randomly selected troponin specimens obtained from patients seen in EDs on each of three traditional shifts (total of nine measurements) on six pre-determined days per month. TATs will be measured from the times the tests are ordered to the times that results are made available to ED personnel. Participants will also have the option of monitoring collection-to-receipt intervals.

Performance Indicators

  • Median TAT of troponin measured from the time troponin is ordered to the time the result is made available to ED personnel
  • Percentage of troponin results reported by each institution’s established reporting deadline

Input forms for quarterly data will be sent to participants approximately three weeks prior to the quarter.
