BACKGROUND: Administrative claims data are used for a wide variety of research and quality assurance purposes. Despite their utility, they are prone to medication exposure misclassification if medications are purchased without utilizing an insurance benefit. Low-cost generic programs (LCGPs) offered at major chain pharmacies are a relatively new and sparsely investigated source of exposure misclassification. Since they were implemented in 2006, LCGPs are now available at 8 of the 10 largest pharmacy chains and include a wide variety of medication classes...

BACKGROUND AND PURPOSE: Premature ventricular complexes (PVCs) detected from long-term ECG recordings have been associated with an increased risk of ischemic stroke. Whether PVCs seen on routine ECG, commonly used in clinical practice, are associated with an increased risk of ischemic stroke remains unstudied. METHODS: This analysis included 24 460 participants (aged, 64.5+9.3 years; 55.1% women; 40.0% blacks) from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study who were free of stroke at the time of enrollment...

BACKGROUND: HMG-CoA reductase inhibitors (statins) reduce the risk of venous thromboembolism (VTE) in healthy people. Statins reduce levels of inflammation biomarkers; however, the mechanism for the reduction in VTE risk is unknown. AIM: In a large cohort of healthy people, we studied associations of statin use with plasma hemostatic factors related to VTE risk. METHODS: Cross-sectional analyses were performed in the Multi-Ethnic Study of Atherosclerosis (MESA), a cohort study of 6814 healthy men and women aged 45-84 years, free of clinical cardiovascular disease at baseline; 1001 were using statins at baseline...

OBJECTIVES: Risk factors have been described for spontaneous intracerebral hemorrhage (ICH); their relative contribution to lobar vs nonlobar hemorrhage location is less clear. Our purpose here was to investigate risk factors by hemorrhage location. METHODS: This case-control study prospectively enrolled subjects with first-ever spontaneous ICH and matched each with up to 3 controls by age, race, and gender. Conditional stepwise logistic regression modeling was used to determine significant independent risk factors for lobar and nonlobar ICH...

OBJECTIVES: To determine the association between physical inactivity (that is, a sedentary lifestyle) and incident idiopathic pulmonary embolism. DESIGN: Prospective cohort study. SETTING: Nurses' Health Study. PARTICIPANTS: 69 950 female nurses who completed biennial questionnaires from 1990 to 2008. Main outcome measures The primary outcome was idiopathic pulmonary embolism confirmed in medical records. Multivariable Cox proportional hazards models controlled for age, body mass index (BMI), energy intake, smoking, pack years, race, spouse's educational attainment, parity, menopause, non-aspirin non-steroidal anti-inflammatory drugs, warfarin, multivitamin supplements, hypertension, coronary heart disease, rheumatological disease, and dietary patterns...

Pulmonary embolism (PE) is common and associated with significant morbidity and mortality. An association between obesity and PE has been suggested, but the nature of the association has not been well defined. We performed a prospective cohort study of 87,226 women in the Nurses' Health Study (1984-2002) to define the association between BMI and the risk of incident PE. Primary exposure was BMI (<22.5, 22.5-24.9, 25.0-27.4, 27.5-29.9, 30.0-34.9, and >or=35.0 kg/m(2)). Primary outcome was idiopathic PE (medical record confirmed cases of PE not associated with prior surgery, trauma, or malignancy)...

BACKGROUND: Anticoagulation therapy with warfarin is widely considered the standard of care for stoke prophylaxis in patients with atrial fibrillation who are at high risk of stroke. Community-based studies in the US have reported that the effectiveness of anticoagulation varies by management approach and that patients receiving warfarin have international normalised ratio (INR) values within the target therapeutic range less than half the time. OBJECTIVE: To estimate the lifetime societal costs and health benefits of warfarin therapy to prevent strokes, specifically in elderly patients (mean age 70 years) with atrial fibrillation who are at high risk of stroke, when anticoagulation is managed through usual care versus anticoagulation management services, where dedicated anticoagulation professionals (e...

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)...
