Why convenience matters
More convenient testing should help patients adhere with their prescribed PT/INR testing frequency.  It has been proven that patients that adhere to their monitoring schedule spend more time in their therapeutic range, which results in lower incidence of stroke¹ or bleeding.²  From a test frequency standpoint, data shows that 50–60% of patients can be expected to remain in their target range if monitoring of INR occurs monthly, 77–85% if monitored weekly and up to 92% if monitored every three days.³  Patients who spend a high proportion of time (> 70%) in the therapeutic range achieve better clinical outcomes.^4,5

Evidence suggests that patients who have a strong connection with their healthcare professional adhere better to their anticoagulant therapy plan.³ The CoaguChek XS mPOC kit helps enhance the relationship between patients and their healthcare providers. Patients enjoy increased convenience through PT/INR self-testing and physicians can be more confident they can optimize treatment decisions effectively as they have access to accurate patient data in near real-time.

"As healthcare systems face continued pressure to deliver improved access to care at a lower cost, increased connectivity between HCPs and patients becomes even more important," said Jennifer Zinn, Senior Vice President of Point of Care, Roche Diagnostics. "This innovative solution also supports making patient self-testing a standard of care to monitor warfarin therapy."

Usual care or management of patients on warfarin therapy includes up to weekly visits to the lab or doctor's office for PT/INR testing - usually with a venipuncture (blood drawn from a vein) and 2-3 day wait for the lab results. The CoaguChek XS mPOC kit engages patients in their care with a simple finger stick and 60-second test with just a drop of blood giving patients the independence to continue their normal daily activities and quality of life while maintaining connections with their HCPs. The result is automatically communicated via Bluetooth to the CoaguChek mPOC app on the patient's iPhone or iPad which transmits the result to CoaguChek Link – an online PT/INR data management solution.⁶ The managing clinician can then use CoaguChek Link to access - and act on – the results.

More about the CoaguChek XS system
Since 1993, CoaguChek® systems from Roche have set the standard in point-of-care INR testing for patients on oral anticoagulant therapy– giving clinicians increased confidence in making critical treatment decisions.  CoaguChek is a proud market leader, with over 1 million CoaguChek XS meters in use around the world and over 250,000 CoaguChek XS PT test strips used per day.  Nine of the top 10 U.S. integrated health networks (IHNs) choose CoaguChek technology. ⁷

More about the CoaguChek Patient Services
Since 2008, CoaguChek® Patient Services, an Independent Diagnostic Testing Facility, has offered support for patients who test from home and the healthcare professionals who manage their treatment.  In a 2012 survey, 93% CoaguChek Patient Services patients reported being satisfied or highly satisfied with the service and 92% said that testing at home had a positive impact on their quality of life.

More about anticoagulant therapy
Millions of people worldwide are taking Vitamin K Antagonists (VKAs) such as Coumadin® and warfarin for a variety of indications or conditions, such as atrial fibrillation (AF), deep vein thrombosis (DVT), pulmonary embolism (PE), and the presence of a mechanical heart valve (MHV). To best monitor the efficacy of VKAs, the prothrombin time PT (INR) needs to be frequently measured. This test can be performed at home using a small drop of blood from a patient's fingertip. Compared with usual care or management in an anticoagulation clinic, patient self-testing has been shown to result in more time spent in the therapeutic range,^8-10 fewer very high or very low INR values,¹⁰ fewer thromboembolic events,^1,2 fewer major hemorrhages,² lower mortality,² improved patient quality of life¹¹ and better treatment satisfaction.¹¹

More about PT/INR
Taking the correct dose is crucial for effective anticoagulation treatment. The correct dose is established by measuring how long it takes blood to clot, and is called the prothrombin time (PT). The International Normalized Ratio (INR) is used to harmonize PT results from different test methods.  The proportion of time INR values are within the upper and lower target value is called Time in Therapeutic Range, or TTR. This is important because the more time patients are in range, the less chance of complications, such as blood clots or excessive bleeding.
