BACKGROUND Chronic obstructive pulmonary disease (COPD) is a growing cause of morbidity and mortality worldwide, and accurate estimates of the prevalence of this disease are needed to anticipate the future burden of COPD, target key risk factors, and plan for providing COPD-related health services. We aimed to measure the prevalence of COPD and its risk(More)
BACKGROUND The Patient Reported Outcomes Measurement Information System 43-item short form (PROMIS-43) and the five-level EQ-5D (EQ-5D-5L) are recently developed measures of health-related quality of life (HRQL) that have potentially broad application in evaluating treatments and capturing burden of respiratory-related diseases. The aims of this study were:(More)
This study aimed to compare strategies for chronic obstructive pulmonary disease (COPD) case finding using data from the Burden of Obstructive Lung Disease study. Population-based samples of adults aged ≥40 yrs (n = 9,390) from 14 countries completed a questionnaire and spirometry. We compared the screening efficiency of differently staged algorithms that(More)
BACKGROUND Inhaled therapies are the cornerstone of pharmacologic management for COPD. Each device requires a unique series of steps to be most effective, making appropriate instruction in inhaler technique a key part of the management of COPD. OBJECTIVES Examine characteristics of patients and devices associated with poor technique among patients with(More)
Comparative effectiveness research (CER) studies involving multiple institutions with diverse electronic health records (EHRs) depend on high quality data. To ensure uniformity of data derived from different EHR systems and implementations, the CER Hub informatics platform developed a quality assurance (QA) process using tools and data formats available(More)
RATIONALE Smoking cessation is the most important intervention for patients with chronic obstructive pulmonary disease (COPD). What leads smokers with COPD to quit smoking remains unknown. OBJECTIVES We sought to examine the association between respiratory symptoms and other markers of COPD severity with intention to quit smoking among a cohort of(More)
Because of the advent of highly effective treatments, routine screening for HIV and hepatitis C virus (HCV) has been recommended for many Americans. This study explored the perceived barriers surrounding routine HIV and HCV screening in a diverse sample of community health centers (CHCs). The Community Health Applied Research Network (CHARN) is a(More)
BACKGROUND The mission of the Community Health Applied Research Network (CHARN) is to build capacity to carry out Patient-Centered Outcomes Research at community health centers (CHCs), with the ultimate goal to improve health care for vulnerable populations. OBJECTIVES The CHARN Needs Assessment Staff Survey investigates CHCs' involvement in research, as(More)
BACKGROUND The Community Health Applied Research Network, funded by the Health Resources and Services Administration, is a research network comprising 18 Community Health Centers organized into four Research Nodes (each including an academic partner) and a data coordinating center. The network represents more than 500,000 diverse safety net patients across(More)
