Analysis of Inter-Observer Agreement of Adjudication of Colors of Pad Colors of Doac Dipstick to Determine Presence or Absence of Direct Oral Anticoagulants in Outpatients' Urine Samples

Background: The efficacy and safety of direct oral anticoagulants (DOACs) in patients with thromboembolic disease is closely related to patient's adherence to therapy. Objective documentation of drug intake is a useful tool for patients' education and improvement of adherence to treatment but may be improved by accurate point-of-care (POCT) testing. Results of DOAC Dipstick may be one of these methods but may depend on interpretation variability.
