METHODS The study followed a(More)
We examined the patient activation measure's (PAM's) association with process and health outcomes among adults with chronic conditions. Patients with high PAM scores were significantly more likely to perform self-management behaviors, use self-management services, and report high medication adherence, compared to patients with the lowest PAM scores. This(More)

PAM scores from a 2004 survey on 1180 randomly sampled adults with diabetes and health information from a 2006 diabetes registry were the data sources(More)
BACKGROUND Validated psychometric tools measuring quality of life, asthma control, and asthma severity have been developed, but their relationships with each other and with other important patient-centered outcomes have not been rigorously assessed. OBJECTIVE To use factor analysis to evaluate the relationships of these validated tools with each other and(More)
Few studies have quantitatively addressed the relationship between asthma-specific quality of life and asthma control as assessed by validated tools. Questionnaires were completed at home by a random sample of 542 adult asthmatic patients. The correlations of the two asthma control tools (Asthma Control Test and Asthma Therapy Assessment Questionnaire) with(More)
BACKGROUND Prior studies suggest that allergist care improves asthma outcomes, but many of these studies have methodological shortcomings. OBJECTIVE We sought to compare patient-based and medical utilization outcomes in randomly selected asthmatic patients cared for by allergists versus primary care providers. METHODS A random sample of 3568 patients(More)
BACKGROUND The Agency for Healthcare Research and Quality ranks prevention of venous thromboembolism (VTE) as a top priority for patient safety; however, no guidelines or population-based research exist to guide management for podiatric surgery patients. The objective of our study was to determine the incidence and risk factors for postprocedure VTE in(More)
OBJECTIVES To establish longitudinal validation of a new tool, the Asthma Symptom Tracker (AST). AST combines weekly use of the Asthma Control Test with a color-coded graph for visual trending. METHODS Prospective cohort study of children age 2 to 18 years admitted for asthma. Parents or children (n = 210) completed baseline AST assessments during(More)
PURPOSE Advanced imaging is commonly used for staging of early-stage breast cancer, despite recommendations against this practice. The objective of this study was to evaluate and compare use of imaging for staging of breast cancer in two integrated health care systems, Kaiser Permanente (KP) and Intermountain Healthcare (IH). We also sought to distinguish(More)
OBJECTIVE To determine if differences between English- and Spanish-speaking parents in ratings of their children's health care can be explained by need for interpretive services.
