BACKGROUND:  Warfarin and direct oral anticoagulants (DOACs) are used for the initial treatment and secondary prevention of venous thromboembolism (VTE), and have similar efficacy. Patient concerns and preferences are important considerations when selecting an anticoagulant, yet these are not well studied. METHODS:  VTE patients ( n  = 519) were surveyed from online sources (, and National Blood Clot Alliance Facebook followers [ n  = 495]) and a haematology clinic in Vermont ( n  = 24)...

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, and it leads to significant morbidity and mortality, predominantly from ischemic stroke. Vitamin K antagonists, mainly warfarin, have been used for decades to prevent ischemic stroke in AF, but their use is limited due to interactions with food and other drugs, as well as the requirement for regular monitoring of the international normalized ratio. Rivaroxaban, a direct factor Xa inhibitor and the most commonly used non-vitamin K oral anticoagulant, avoids many of these challenges and is being prescribed with increasing frequency for stroke prevention in non-valvular AF...

Patient Self-testing (PST) could be an option for present anticoagulation therapy monitoring, but current evidence on its cost-effectiveness is limited. This study aims to estimate the cost-effectiveness of PST to other different care approaches for anticoagulation therapy in Thailand, a low-to-middle income country (LMIC). A Markov model was used to compare lifetime costs and quality-adjusted life years (QALYs) accrued to patients receiving warfarin through PST or either anticoagulation clinic (AC) or usual care (UC)...

Objective: To investigate the cost-effectiveness of the first patient self-paying pharmacist-assisted warfarin monitoring (PAWM) program in Taiwan. Design: A Markov model with a 1-month cycle length and a 20-year time horizon was employed in this study. The model is composed of the following eight states: three no-event states (i.e. 'subtherapeutic,' 'within therapeutic' and 'supratherapeutic' states), two serious adverse events (AEs) (i.e. bleeding and thromboembolism), two sequelae states and death...

Anticoagulant overdose is associated with major bleeding complications. Rapid coagulation sensing may ensure safe and accurate anticoagulant dosing and reduce bleeding risk. Here, we report the novel use of Laser Speckle Rheology (LSR) for measuring anticoagulation and haemodilution status in whole blood. In the LSR approach, blood from 12 patients and 4 swine was placed in disposable cartridges and time-varying intensity fluctuations of laser speckle patterns were measured to quantify the viscoelastic modulus during clotting...

BACKGROUND: Patients on chronic warfarin therapy require regular laboratory monitoring to safely manage warfarin. Recent studies have challenged the need for routine monthly blood draws in the most stable warfarin-treated patients, suggesting the safety of less frequent laboratory testing (up to every 12 weeks). De-implementation efforts aim to reduce the use of low-value clinical practices. To explore barriers and facilitators of a de-implementation effort to reduce the use of frequent laboratory tests for patients with stable warfarin management in nurse/pharmacist-run anticoagulation clinics, we performed a mixed-methods study conducted within a state-wide collaborative quality improvement collaborative...

Vitamin K antagonists such as warfarin are the most widely used class of oral anticoagulants. Due to a narrow therapeutic window, patients on warfarin require regular monitoring. Self-testing using point-of-care (POC) diagnostic devices is available, but cost makes this monitoring method beyond reach for many. The main objective of this research was to assess the clinical utility of a low-cost, paper-based lateral flow POC diagnostic device developed for anticoagulation monitoring without the need for a separate electronic reader...

Oral anticoagulant therapies with the anti-vitamin K drugs (AVK), warfarin, acenocoumarol and phenprocoumon, are employed in primary and secondary anti-thrombotic prophylaxis in patients with venous thromboembolism, atrial fibrillation and cardiac mechanical valves. However, a monitoring test such as the International Normalized Ratio (INR) is required. The periodic monitoring of this therapy entails discomfort for the patients. Telemedicine and telecare can provide significant aid in the management of this therapy allowing patients to perform the test at home or anywhere else with a portable device, i...

Introduction When rapid feedback to physicians must be provided, e.g. monitoring therapy with the oral anticoagulant warfarin or providing therapeutic support for patients undergoing cancer chemotherapy, the involvement of pharmacists is required for outpatients. We launched a pharmacist outpatient service for patients with cancer taking oral anti-cancer agents. We evaluated the role and usefulness of the pharmacist outpatient service for these patients undergoing oral monotherapy with anti-cancer agents. Methods Data regarding prescription recommendations were collected from the drug management guidance records of 154 patients who consulted the pharmacist outpatient service between July 2013 and September 2015...

Extended-interval monitoring of warfarin has been proposed to reduce follow-up burden and improve patient satisfaction. We aimed to make an initial assessment of anticoagulation satisfaction before and after an extended-interval warfarin monitoring intervention. We conducted a translational prospective single-arm pilot study of extended-interval warfarin monitoring in five pharmacist-managed anticoagulation clinics. Patients meeting CHEST guideline criteria for extended-interval warfarin monitoring began progressive extended-interval follow-up (6, 8, and 12 weeks thereafter)...

BACKGROUND: Effective management of patients using warfarin is resource-intensive, requiring frequent in-clinic testing of the international normalized ratio (INR). Patient self-testing (PST) using portable at-home INR monitoring devices has emerged as a convenient alternative. As revealed by The Home INR Study (THINRS), event rates for PST were not significantly different from those for in-clinic high-quality anticoagulation management (HQACM), and a cumulative gain in quality of life was observed for patients undergoing PST...

The complexity of managing children with chronic disease has led to an increase in the use of long-term warfarin therapy. Time in therapeutic range (TTR) is the preferred method for determining efficacy and stability of warfarin management. This study aimed to determine the TTR achievement and incidence of adverse events among pediatric warfarin patients managed by an anticoagulation clinic over 12 months and to compare TTR achievement between patients self-testing (PST) at home and those monitored using routine methods...

Long-term treatment with warfarin is recommended for patients with atrial fibrillation at risk of stroke and those with recurrent venous thrombosis or prosthetic heart valves. Patient education before commencing warfarin - regarding signs and symptoms of bleeding, the impact of diet, potential drug interactions and the actions to take if a dose is missed - is pivotal to successful use. Scoring systems such as the CHADS2 score are used to determine if patients with atrial fibrillation are suitable for warfarin treatment...

BACKGROUND: Patient self-management (PSM) in adults is safer and more cost effective than conventional management. Warfarin is a narrow therapeutic index drug with individual patient response to changes and frequently a long-term therapy. Children and their families are proposed to be able to effectively manage their child's warfarin therapy. Increased health related quality of life is highly associated with effective therapy in patients with chronic conditions. OBJECTIVES: The aim of this study is to evaluate the safety and efficacy of PSM over time including HRQOL and variables that may influence PFU success at PSM...

BACKGROUND: Vitamin K antagonists are commonly used for the prevention of thromboembolic events. Patient self-monitoring of vitamin K antagonists has proved superior to usual care. Dabigatran has been shown, relative to warfarin, to reduce thromboembolic events without increasing bleeding. METHODS: We constructed a Markov model to compare vitamin K self-monitoring strategies to dabigatran including effectiveness and costs of monitoring and complications (thromboembolism and major bleeding)...

Anticoagulation with warfarin requires frequent evaluation of the international normalized ratio (INR), and less invasive testing devices are available for use by clinicians at the point-of-care (POC) and by patients who self-test (PST). Despite commercial availability and positive results of published studies, evidence suggests that adoption of less invasive (POC/PST) testing in the United States is slow. Considering the equivalence of results and logistical advantages of POC/PST testing, slow uptake may indicate a gap in quality of care warranting evaluation and possibly intervention...
