Key result
Coumatrak fingerstick monitoring shows unacceptable precision and accuracy for outpatient anticoagulation management.
Why the study?
There is a need to monitor anticoagulation accurately, inexpensively, and rapidly, but the accuracy and precision of the Coumatrak fingerstick method in a large outpatient clinic was uncertain.
Is the Coumatrak fingerstick method accurate and precise for monitoring anticoagulation in an outpatient clinic?

Is the Coumatrak fingerstick method accurate and precise for monitoring anticoagulation in an outpatient clinic?
The Coumatrak fingerstick method for anticoagulation monitoring demonstrated unacceptable precision and accuracy in a large outpatient clinic setting, requiring further study before widespread use.
Foulis et al. (1995) conducted an observational in Anticoagulation monitoring. Coumatrak system vs. Standard method was evaluated on Precision and accuracy. The Coumatrak fingerstick method for monitoring anticoagulation demonstrated unacceptable precision and accuracy in a large outpatient clinic setting.
