BACKGROUND Self-report measures of medication nonadherence confound the extent of and reasons for medication nonadherence. Each construct is assessed with a different type of psychometric model, which dictates how to establish reliability and validity. OBJECTIVES To evaluate the psychometric properties of a self-report measure of medication nonadherence(More)
INTRODUCTION Following national recommendations for physical activity, diet, and nonsmoking can reduce both incident and recurrent coronary heart disease. Prevalence data about combinations of behaviors are lacking. This study describes the prevalence of full adherence to national recommendations for physical activity, fruit and vegetable consumption, and(More)
BACKGROUND More than half of veterans who use Veterans Health Administration (VA) care are also eligible for Medicare via disability or age, but no prior studies have examined variation in use of outpatient services by Medicare-eligible veterans across health system, type of care or time. OBJECTIVES To examine differences in use of VA and Medicare(More)
BACKGROUND In anticipation of applying Appropriate Use Criteria for percutaneous coronary intervention (PCI) quality improvement, we determined the prevalence of appropriate, uncertain, and inappropriate PCIs stratified by indication for all PCIs performed in the state of Washington. METHODS AND RESULTS Within the Clinical Outcomes Assessment Program, we(More)
BACKGROUND Although oral hypoglycemic agents (OHAs) are an essential element of therapy for the management of type 2 diabetes, OHA adherence is often suboptimal. Pharmacists are increasingly being integrated into primary care as part of the move towards a patient-centered medical home and may have a positive influence on medication use. We examined whether(More)
BACKGROUND Thiazolidinediones are oral diabetes medications that selectively activate peroxisome proliferator-activated receptor gamma and have potent anti-inflammatory properties. While a few studies have found improvements in pulmonary function with exposure to thiazolidinediones, there are no studies of their impact on asthma exacerbations. Our objective(More)
PURPOSE Poor adherence to cardioprotective medications after acute coronary syndrome (ACS) hospitalization is associated with increased risk of rehospitalization and mortality. Clinical trials of multifaceted interventions have improved medication adherence with varying results. Patients' perspectives on interventions could help researchers interpret(More)
NCQA seeks comments on the proposed new measure for inclusion in the HEDIS 2016 measurement set: Statin Therapy for Patients With Diabetes. The percentage of patients 40–75 years of age with diabetes who do not have clinical atherosclerotic cardiovascular disease (ASCVD) and were dispensed a statin of any dosage intensity that they remained on for at least(More)
BACKGROUND Patient nonadherence to cardiac medications following acute coronary syndrome (ACS) is associated with increased risk of recurrent events. However, the prevalence of cognitive dysfunction and poor health literacy among ACS patients and their association with medication nonadherence are poorly understood. METHODS We assessed rates of cognitive(More)
BACKGROUND Thiazolidinediones (TZDs) are oral antihyperglycemic medications that are selective agonists to peroxisome proliferator-activated receptor gamma and have been shown to have potent anti-inflammatory effects in the lung. OBJECTIVE The purpose of this study was to assess whether exposure to TZDs is associated with a decreased risk of chronic(More)
