Recently published study by Refaai et. al assessed the performance of the microINR system in patient self-testing (PST). Vitamin K antagonists (VKA), such as warfarin, are commonly used oral anticoagulants for thrombotic disorders. The anticoagulation effect of VKA therapy is monitored by the international normalized ratio (INR) method of reporting the prothrombin time. INR point of care (POC) instruments evolvement reduced clinic visits, provided more testing options and locations, and allowed immediate clinical evaluation and dosage adjustment. Furthermore, the patient self-testing (PST) model, where patients perform INR testing by themselves and report results to a healthcare provider (HCP), provided significant advantages to warfarin anticoagulation monitoring. Additionally, the patient self-management (PSM) model upon which patients perform by themselves both INR testing and the dose adjustment augmented INR POC benefits. In comparison to the other regular monitoring models, PST and PSM models showed significant decrease in thromboembolic and bleeding events and provided better clinical outcomes. This is mainly due to the improvement in the time in therapeutic range.
The study assessed the performance of the microINR system in patient self-testing (PST). Study data demonstrates equivalent performance between self-testing patients’ and HCPs’ microINR results. The study concluded that microINR is a reliable warfarin anticoagulation monitoring system for self-testing and professional use at POC settings. It can help improve the therapeutic range and clinical outcomes of VKA anticoagulated patients.
