BACKGROUND: Rheumatic heart disease (RHD) is a leading cause of premature mortality in low- and middle-income countries (LMICs). Women of reproductive age are a unique and vulnerable group of RHD patients, due to increased risk of cardiovascular complications and death during pregnancy. Yet, less than 5% of women of childbearing age with RHD in LMICs use contraceptives, and one in five pregnant women with RHD take warfarin despite known teratogenicity. It is unclear whether this suboptimal contraception and anticoagulant use during pregnancy is due to lack of health system resources, limited health literacy, or social pressure to bear children...

Atrial fibrillation (AF) is a very common cardiac arrhythmia, and its prevalence is increasing along with aging in the developed world. This review discusses racial differences in the epidemiology and treatment of AF between African-American and Caucasian patients. Additionally, the effect of race on warfarin and novel oral anticoagulant use is discussed, as well as the role that physicians and patients play in achieving optimal treatment outcomes. Despite having a lower prevalence of AF compared with Caucasians, African-Americans suffer disproportionately from stroke and its sequelae...

Patients on warfarin therapy need to achieve and maintain anticoagulation control in order to experience the benefits of treatment while minimizing bleeding risk. Low health literacy skills may hinder patients' ability to use and adhere to warfarin in a safe and effective manner. The authors conducted this study to evaluate the relationship between health literacy and anticoagulation control among patients on chronic warfarin therapy. Participants were recruited from 2 diverse anticoagulation clinics in North Carolina...

Over a decade of research in health literacy has provided evidence of strong links between literacy skills of patients and health outcomes. At the same time, numerous studies have yielded insight into efficacious action that health providers can take to mitigate the negative effects of limited literacy. This small study focuses on the adaptation, review and use of two new health literacy toolkits for health professionals who work with patients with two of the most prevalent chronic conditions, arthritis and cardiovascular disease...

BACKGROUND: Warfarin is a high-risk medication where patient information may be critical to help ensure safe and effective treatment. Considering the time constraints of healthcare providers, the internet can be an important supplementary information resource for patients prescribed warfarin. The usefulness of internet-based patient information is often limited by challenges associated with finding valid and reliable health information. Given patients' increasing access of the internet for information, this study investigated the quality, suitability and readability of patient information about warfarin presented on the internet...

Despite the well documented benefit of echocardiography in acute coronary syndromes, its wide-scale use in the Caribbean is limited by access, health literacy and affordability. Because of the limited use of echocardiography in the region, routine complications of acute myocardial infarction (AMI) are not fully appreciated and may go unrecognized, further contributing to increased cardiovascular morbidity and mortality. It is therefore necessary to bring focus to this common clinical condition and highlight the clinical utility of echocardiography in facilitating timely and accurate diagnosis...

BACKGROUND AND PURPOSE: Warfarin is an effective drug for the prevention of thromboembolism in the elderly. The major risk for patients taking warfarin is bleeding. We aimed to assess the impact of psychosocial factors, including mood, cognition, social isolation, and health literacy on warfarin instability among community-based elderly patients. METHODS: A case-control study was conducted between March 2008 and June 2009 in a community-based setting. Cases were patients previously stabilized on warfarin who recorded an international normalized ratio‚Č•6...

Warfarin is a widely used oral anticoagulant. It is highly efficacious for the treatment and prevention of thromboembolic disorders despite its narrow therapeutic window. Poor compliance with warfarin is common and a major contributor to poor anticoagulation control. A number of psychosocial issues (e.g. depressive symptoms, attitudinal and behavioral factors, cognitive function, lack of social support, limited English proficiency, health illiteracy) have been associated with warfarin non-compliance among patients in anticoagulation clinics...

A patient education workgroup was developed on a progressive care medical/vascular surgical unit. The workgroup identified patient education needs regarding discharge education for postsurgical patients and those discharging with oral anticoagulants (OAC). Staff surveys aided the workgroup in identifying a need for additional discharge education for patients and families. After various methods of patient education were explored, it was determined the workgroup could best meet the needs of the patient population through a class format providing group discussion and interaction...

Prior studies suggest patient self-testing (PST) of prothrombin time (PT) can improve the quality of anticoagulation (AC) and reduce complications (e.g., bleeding and thromboembolic events). "The Home INR Study" (THINRS) compared AC management with frequent PST using a home monitoring device to high-quality AC management (HQACM) with clinic-based monitoring on major health outcomes. A key clinical and policy question is whether and which patients can successfully use such devices. We report the results of Part 1 of THINRS in which patients and caregivers were evaluated for their ability to perform PST...

Implementing preventive care and achieving adherence to preventive care plans is a difficult task for general practitioners. If we consider the preventive elements of the problems described in the focus articles in this month's issue of Australian Family Physician, or for cardiovascular disease prevention for example, the preventive activity we are asking our patients to undertake can be a 'real ask' and for many, too unpalatable.

OBJECTIVE: Warfarin is a medication commonly prescribed to prevent strokes associated with certain medical conditions such as atrial fibrillation; however, little is known about how people taking warfarin perceive the goal of therapy and how they describe strokes. We assessed the stroke-related health literacy of anticoagulated patients to inform ways in which to improve health communication among people taking warfarin. METHODS: We conducted a mixed-methods study of an ethnically and linguistically diverse sample of people taking warfarin to prevent stroke (N=183) and measured literacy using the short-form Test of Functional Health Literacy in Adults...

Despite the importance of clinician-patient communication, little is known about rates and predictors of medication miscommunication. Measuring rates of miscommunication, as well as differences between verbal and visual modes of assessment, can inform efforts to more effectively communicate about medications. We studied 220 diverse patients in an anticoagulation clinic to assess concordance between patient and clinician reports of warfarin regimens. Bilingual research assistants asked patients to (1) verbalize their prescribed weekly warfarin regimen and (2) identify this regimen from a digitized color menu of warfarin pills...

BACKGROUND: Little is known about whether health literacy affects anticoagulation-related outcomes. OBJECTIVE: To assess how health literacy is associated with warfarin knowledge, adherence, and warfarin control (measured by the international normalized ratio [INR]). DESIGN: Survey. PARTICIPANTS: Patients taking warfarin through an anticoagulation clinic. MEASUREMENTS: Health literacy was measured using the short-form Test of Functional Health Literacy in Adults (s-TOFHLA), dichotomized as "limited" (score 0 to 22) and "adequate" (score 23 to 36)...

BACKGROUND: The ability to use printed material to function in society (literacy) and to handle basic numerical concepts (numeracy) may have implications in patients' ability to follow dosing schedules. We examined literacy and numeracy skills among patients on warfarin and explored their association with anticoagulation control. METHODS AND RESULTS: Patients older than 50 years attending two anticoagulation management units were prospectively enrolled. We measured literacy, numeracy, and international normalized ratio (INR)...

The number of patients on anticoagulation therapy has increased dramatically over the past two decades. Yet, few studies have examined the psychosocial barriers of low literacy, culture and inappropriate patient education materials used to teach older African Americans about their anticoagulation therapy. The aims of this study were to investigate literacy levels among older patients, and evaluate the readability and determine the cultural sensitivity of written information used in an anticoagulation management clinic...
