Home health system helps give anticoagulated patients greater control

For most people, coagulation is one of the human body’s most unnoticed processes, although it is one of the most important. When a wound occurs and a blood vessel is damaged, a blood clot forms to stop the bleeding, which allows healing to begin.

Abnormal blood clotting can have life-threatening consequences for those suffering from conditions such as atrial fibrillation, deep vein thrombosis, pulmonary embolism, stroke or heart valve disease. The serious risk posed by clotting often requires these patients to take daily blood thinning medications and perform regular monitoring of clotting levels.

For millions of patients worldwide, managing these conditions involves frequent trips to the doctor’s office or anticoagulation clinic (often between two to four visits every month), which can interfere with work, family and travel commitments. Life can seem to revolve around these visits to have a blood test done, leading to frustration at the inconvenience and anxiety in anticipation of each new test result. The heightened risk of hospitalisation, should clotting levels veer dangerously out of range, can also mean extraordinary health care costs for both patients and providers.

Innovations in e-health - helping people on anticoagulants

Today, thanks to innovations in home health technology, some patients are breaking free of this cycle. Representing another step forward in the e-Health revolution, the new standard in anticoagulation therapy monitoring involves a hand-held meter that allows patients to test their own clotting levels, also known as PT/INR monitoring, from any location. Patients can then transmit the test results directly to the doctor using Bluetooth technology.

Self-testers achieve greater independence, while gaining the reassurance of knowing their result and having the ability to easily share it with their doctor. Patients can monitor their PT/INR levels as often as they wish – anytime, anywhere – and healthcare professionals can use the results to make immediate treatment decisions when necessary to keep their patients’ health on track.

About PT/INR

Taking the correct dose is crucial for efficient anticoagulation treatment. The correct dose is established by measuring how long it takes blood to clot, and is called the Prothrombin Time / International Normalised Ratio (PT/INR). 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.

Patient self-testing studies

Studies show that patients who self-test are more engaged in their own care, test more often and spend more time in range1 – 92 percent of patients who monitor at least every three days can expect to remain in their target range.2 Patients who spend a high proportion of time (> 70%) in the therapeutic range achieve better clinical outcomes.3,4 For providers, this could be a cost-effective approach: more patients in range may lead to fewer hospitalisations and thus a vast reduction in the associated health care costs. Some evidence also suggests that patients with a strong connection with their doctor through self-testing adhere better to therapy and experience stronger health outcomes as a result.1,2,5

Improved quality of life for patients

For many people, travel is one of life’s great pleasures. This is also the case for Erika and Angelika who are both on anticoagulation therapy. Learn about their stories and what impact self-testing has had on their lives.

Travelling with deep vein thrombosis - a patient's perspective

Erika Sojka was 33 years old when she was diagnosed with deep vein thrombosis, which meant that she would have to take anticoagulants and be tested regularly for the rest of her life. Listen to Erika and how self-testing allows her safe travelling.

How self-testing has brought more independence to Veronika

Veronika R. Meyer has always been an avid mountain climber. Due to her heart problem, she had to take anticoagulants and had to be tested regularly. Listen to how Veronika got back to her normal life and how she has climbed up to the top of Mount Everest.

We talked to Dr. Christoph Sucker about why and how anticoagulation therapy and travelling can indeed be a healthy match and what patients need to consider.
