Anticoagulation, self-monitoring

INTRODUCTION: Warfarin induces coagulopathy. Guidelines protocolize reversal of supratherapeutic international normalized ratio (INR) in patients dependent on anticoagulation, but practices vary for reversing warfarin-induced coagulopathy after overdose in non-warfarin-dependent patients. CASE REPORT: This is the report of a 15-year-old female who ingested her father's warfarin (100-200 mg) in a self-harm attempt. At hour 24 post-ingestion, her INR was 2.00 and she was admitted for monitoring...

AIM: This study aimed to explore and understand the barriers perceived by Italian nurses to adopting self-monitoring for managing oral anticoagulation in real-life settings. BACKGROUND: Barriers to self-monitoring implementation for managing oral anticoagulation have been poorly described. DESIGN: The study had a qualitative descriptive and exploratory design with a hybrid approach. METHODS: A literature review was conducted to identify a priori barriers (deductive approach), while a small and semi-structured focus group discussion was performed to explore the contextual barriers experienced by Italian nurses (inductive approach)...

PURPOSE: The aim of this study was to analyze the clinical characteristics of fatal adverse events (AEs) of rivaroxaban combined with aspirin and to underline the importance of the rational use of drugs. METHODS: The WHO global database of reported potential side effects of medicinal products (VigiBase) was searched for fatal AEs in the combined use of rivaroxaban and aspirin, and the clinical characteristics of those cases with sufficient information (vigiGrade completeness score ≥ 0...

Background and Objectives : Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with a five-fold increased risk for acute ischemic stroke (AIS). We aimed to estimate the prevalence of AF in a Lithuanian cohort of stroke patients, and its impact on patients regarding case fatality, functional outcome, and health-related quality of life (HRQoL) at 90 days. Materials and Methods : A single-center prospective study was carried out for four non-consecutive months between December 2018 and July 2019 in one of the two comprehensive stroke centers in Eastern Lithuania...

OBJECTIVE: To explore the effect of the whole-process health management model on the compliance of oral warfarin treatment in patients with non-valvular atrial fibrillation in primary hospitals. METHODS: We retrospectively analyzed the clinical data of 130 patients with non-valvular atrial fibrillation treated in the Department of Cardiovascular Medicine, Hai'an People's Hospital from January 2019 to December 2019. Among them, 63 patients who received routine continuing care were included in the control group, and 67 patients treated with whole-course health management model of primary hospitals were included in the observation group...

BACKGROUND: Atrial fibrillation (AF) is a highly morbid condition which requires long-term adherence to oral anticoagulation and may be associated with adverse quality of life and health care utilization. We developed a relational agent - an interactive smartphone-based intervention accessible regardless of digital or health literacy - to assist individuals residing in rural, Western Pennsylvania, with AF with chronic disease self-management. METHODS: The "Mobile health intervention for rural atrial fibrillation" is a single center, parallel-arm randomized clinical trial for adults with AF funded by the National Institute of Health's National Heart, Lung, and Blood Institute to enroll 264 participants...

Anticoagulation with Vitamin K antagonists (VKA) has always posed challenges in terms of monitoring requirements. These challenges were further exacerbated in the setting of the COVID-19 pandemic, with limited access to and/or avoidance of laboratory testing. The importance of utilizing point of care (POC) health technology for individualized patient management is salient. The foundation of effective home INR monitoring is establishing patient knowledge about their therapy and INR testing proficiency. The eKITE series was developed to support patients in establishing foundational knowledge required for VKA (warfarin) management and INR monitoring...

BACKGROUND: Facilitating appropriate care delivery using electronic health record (digital health) tools is increasing. However, frequently used determinants frameworks seldom address key barriers for technology-associated implementation. METHODS: Semi-structured interviews were conducted in two contexts: the national Veterans Health Affairs (VA) following implementation of an electronic dashboard, a population health tool, and the Michigan Anticoagulation Quality Improvement Initiative (MAQI2 ) prior to implementation of a similar electronic dashboard...

BACKGROUND: Atrial fibrillation (AF) is common in older people and increases the risk of stroke. The feasibility and effectiveness of the implementation of a patient-led AF screening program for older people are unknown. OBJECTIVE: This study aims to examine the feasibility and effectiveness of an AF screening program comprising patient-led monitoring of single-lead electrocardiograms (ECGs) with clinician-coordinated central monitoring to diagnose AF among community-dwelling people aged ≥75 years in Australia...

BACKGROUND: The concomitant use of anticoagulant and antiplatelet medications increases the risk of upper gastrointestinal (GI) bleeding. Two underused evidence-based practices (EBPs) can reduce the risk: de-prescribe unnecessary antiplatelet therapy or initiate a proton pump inhibitor. We describe the development of a multicomponent intervention to increase use of these EBPs in patients treated with warfarin and followed by an anticoagulation monitoring service (AMS), and the design of a pilot pragmatic implementation trial...

Introduction  Anticoagulation monitoring is a major practical and clinical challenge. We assessed the performance of the microINR system in patient self-testing (PST). Methods  This study was performed at four US medical centers. After the training visit of warfarin anticoagulated patients ( n  = 117) on microINR system, PST was performed at home and in two visits to the medical centers. At the medical centers, both PST and healthcare professionals (HCPs) performed duplicate tests with the microINR System...

AIMS: Switching non-adherent patients prescribed anticoagulant treatment to a regime with less monitoring could lead to significant non-adherence. Health beliefs are known to influence medication adherence; however, the extent of this influence is unknown in patients switched from vitamin-K antagonists (VKAs) to direct oral anticoagulants (DOACs). This study aimed to determine adherence to long-term therapy in patients switched from VKAs to DOAC due to low time in therapeutic range (TTR) and if adherence is associated with health beliefs...

PURPOSE: To describe the development of a multidisciplinary anticoagulant safety taskforce (ASTF) to address anticoagulation-related issues across the medication-use system. SUMMARY: Oral and parenteral anticoagulants have been classified as high-alert medications because of their potential for harm. Errors at the point of prescribing, monitoring, and administering therapy have been noted in safety literature. Our hospital system, which includes 1 academic medical center, 6 community hospitals, and 1 long-term care facility, designed a multidisciplinary ASTF to address anticoagulation-related issues...

BACKGROUND AND PURPOSE: Cryptogenic stroke accounts for 30% of ischemic stroke and in such patients, cardiac monitoring leads to increased detection of AF, increased utilization of anticoagulation, and decreased risk of recurrent stroke. We aim to identify differences in inpatient utilization of implantable cardiac monitors (ICMs) in patients with ischemic stroke. METHODS: This is an analysis of the National Inpatient Sample. We included all ischemic stroke hospitalizations nation-wide between Jan 1st 2016 and Dec 31st 2018...

Introduction: For patients with heart valve replacement, self-management can play an essential role in the management of their condition. Aim: This review aimed to identify the aspects of self-management and its clinical outcomes in patients with heart valve replacement. Material and methods: In this systematic review, the peer-reviewed research literature on self-management of patients with heart valve replacement was assessed. Since May 2020, the PubMed, Scopus, and web of science databases were searched regardless of time and language limitations...

INTRODUCTION: Patients with pelvic trauma are at high risk of thromboembolic complications, but effective methods of prophylaxis are still to be accepted widely. The incidence of venous thromboembolism (VTE) has been reported to be as high as 61%, which represents the commonest cause of morbidity and mortality in this cohort. New oral anticoagulants are now available and may be used instead of LMWH injections for extended prophylaxis. Rivaroxaban has not been comprehensively considered in the previous pelvic and acetabular trauma literature, but its known benefits include increased patient compliance, especially in the minority of patients who are unable to self-administer injections, and that it does not require monitoring...

BACKGROUND: Warfarin treatment requires frequent monitoring of INR (international normalized ratio) to adjust dosage in a therapeutic range. In China, patients living in small towns usually go to tertiary hospitals to get warfarin monitoring and dosing, resulting in low frequencies of follow-ups and high incidence of complications. Influenced by the COVID-19 pandemic, patients on warfarin have further reduced their visits to healthcare institutions. While patient self-testing (PST) via using a point-of-care testing device for INR measuring at home has been widely used in developed countries and demonstrated improved clinical outcomes compared to usual care in clinics, it is rarely applied in developing countries, including China...

BACKGROUND: Adherence to oral anticoagulant therapy in patients with atrial fibrillation (AF) in China is low. Patient preference, one of the main reasons for discontinuation of oral anticoagulant therapy, is an unfamiliar concept in China. METHODS AND FINDINGS: A discrete choice experiment (DCE) was conducted to quantify patient preference on 7 attributes of oral anticoagulant therapy: antidote (yes/no), food-drug interaction (yes/no), frequency of blood monitoring (no need, every 6/3/1 month[s]), risk of nonfatal major bleeding (0...

BACKGROUND: The target ranges (TR) for anticoagulation with vitamin K antagonists (VKA) in the Netherlands were changed in 2016 from INR 2.0-3.5 ('low intensity') and INR 2.5-4.0 ('high intensity') to INR 2.0-3.0 and INR 2.5-3.5, respectively. AIM: To assess the effect of the TR change on therapeutic quality control (TQC) in a Dutch regional thrombosis center taking care of approximately 3600-5500 patients annually. METHODS: TQC of chronically treated patients was assessed as the average time in therapeutic range (TTR)...

AIM: This study aimed to develop and validate a nursing self-efficacy scale for OAC management (SE-OAM). BACKGROUND: Oral anticoagulant therapy (OAC) requires specific nursing competencies. Given that self-efficacy acts as a proxy assessment of nursing competence, its measurement is pivotal for addressing educational programs to enhance nursing competence in managing OAC. Thus far, the measurement of self-efficacy in OAC is undermined by the unavailability of valid and reliable tools...
