Background: Low physical activity in patients with chronic obstructive pulmonary disease (COPD) is associated with increased morbidity and mortality. To inform the design of a home-based physical activity promotion program for patients with COPD recently discharged from a minority-serving hospital, we conducted a cohort study to evaluate objectively measured daily physical activity and patient-reported outcomes.
Methods: This was a 12-week prospective cohort study of patients with a physician diagnosis of COPD recently hospitalized (≤ 12 weeks) for respiratory symptoms.
Rationale: Physical inactivity among patients with chronic obstructive pulmonary disease is associated with exacerbations requiring high-cost health care utilization including urgent, emergent, and hospital care.
Objectives: To examine the effectiveness of a behavioral lifestyle physical activity intervention combined with chronic obstructive pulmonary disease self-management education to prevent high-cost health care utilization.
Methods: This was an analysis of secondary outcomes of the Chronic Obstructive Pulmonary Disease Self-Management Activation Research Trial, a two-arm randomized trial of stable adult outpatients with chronic obstructive pulmonary disease recruited from primary care and pulmonary clinics.
Physical inactivity is an underrecognized and undertreated lifestyle behavior among patients with chronic obstructive pulmonary disease and is independently associated with a number of adverse health-related outcomes. Pulmonary rehabilitation with exercise training provides an efficacious intervention with short-term improvements, but it is an infrequently used modality and does not consistently result in longer term increases in physical activity. Similarly, pedometer self-monitoring with coaching has demonstrated short-term increases in physical activity.

This study aimed to summarize the evidence on effectiveness of self-management interventions and identify subgroups of COPD patients who benefit most.
Methods: Randomized trials of self-management interventions between 1985 and 2013 were identified through a systematic literature search.
Background: Commercially available pedometers have been used as tools to measure endpoints in studies evaluating physical activity promotion programs. However, their accuracy in patients recovering from COPD exacerbations is unknown. The objectives of this study were to 1) assess the relative accuracy of different commercially available pedometers in healthy volunteers and 2) evaluate the accuracy of the top-performing commercially available pedometer in patients recovering from COPD exacerbations following hospital discharge.

IPF is a form of chronic, progressive fibrosing interstitial pneumonia and has more scarring, less inflammation, and poorer prognosis than most other ILD forms. Exacerbation of IPF is rapid, with unpredictable deterioration of lung function, and is associated with short-term mortality.

Objectives: To determine effectiveness of a behavioral intervention intended to increase daily physical activity with the goal of improving health-related quality of life and functional performance.
Methods: We conducted a randomized trial among patients with COPD cared for in primary care and pulmonary clinics.
Objective: To describe the recruitment methods, study participation rate, and baseline characteristics of a representative sample of outpatients with COPD eligible for pulmonary rehabilitation participating in a trial of a lifestyle behavioral intervention to increase physical activity.
Setting And Design: A patient registry was developed for recruitment using an administrative database from primary care and specialty clinics of an academic medical center in northeast Texas for a parallel group randomized trial.
Results: The registry was comprised of 5582 patients and over the course of the 30 month recruitment period 325 patients were enrolled for an overall study participation rate of 35.
Objectives: Few studies have characterized healthcare resource utilization among patients with idiopathic pulmonary fibrosis. The objective of this study is to assess healthcare resource utilization among patients with idiopathic pulmonary fibrosis as compared to members without this condition.
Methods: Patients newly diagnosed with idiopathic pulmonary fibrosis were identified from a national administrative claims database (2006-2011) as having ≥ 2 claims with idiopathic fibrosing alveolitis, or ≥ 1 claim with idiopathic fibrosing alveolitis and ≥ 1 claim with post-inflammatory pulmonary fibrosis (earliest claim with idiopathic fibrosing alveolitis denoted the index date), a procedure of lung biopsy or high-resolution computed tomography within ± 90 days of the index date, 12-month pre-index continuous enrollment, plus ≥ 2 confirmatory idiopathic fibrosing alveolitis diagnoses after the procedure.
Rationale: The relationship between self-efficacy and health behaviors is well established. However, little is known about the relationship between self-efficacy and health-related indicators among patients with chronic obstructive pulmonary disease (COPD).
Objectives: The purpose of this cross-sectional cohort study was to test the hypothesis that the total score and specific subdomain scores of the COPD Self-Efficacy Scale (CSES) are associated with functional capacity and quality of life in a group of patients with moderate to severe COPD.
Purpose: Limited evidence in the United States suggests that among patients with chronic obstructive pulmonary disease (COPD), rural residence is associated with higher hospitalization rates and increased mortality. However, little is known about the reasons for these disparities. This study's purpose was to describe the health status of rural versus urban residence among patients with COPD and to examine factors associated with differences between these 2 locations.

One target is physical inactivity because it leads to disability and contributes to poor physical and mental health. Unfortunately, less than 1% of eligible patients have access to gold-standard pulmonary rehabilitation.
View Article and Find Full Text PDFBackground: Chronic obstructive pulmonary disease (COPD) is an illness that affects patients on multiple levels, both physically and psychologically. While there is a growing body of evidence for the efficacy of self-management among patients with COPD, little evidence is available on the optimal content and methods for delivering self-management support.
Aims: The purpose of this study was to address gaps in the literature on self-management support by examining patients' responses to questions about goals, needs, and expectations regarding self-management using qualitative methods in a broadly representative sample of patients with moderate to severe COPD.
Introduction: Individuals with chronic obstructive pulmonary disease (COPD) experience irreversible airflow obstruction, dyspnea, coughing, and fatigue. One of the goals of treating individuals with COPD is to improve their quality of life. The aim of this research was to evaluate the 2009 Texas Behavioral Risk Factor Surveillance System (BRFSS) as a method for surveillance of COPD by identifying factors associated with impaired health-related quality of life (HRQoL) among respondents with COPD as well as comment on differences between the COPD and non-COPD population in a state representative sample.

However, there is confusion over what processes are involved, how the value of self-management should be determined, and about the research priorities. To gain more insight into and agreement about the content of programmes, outcomes, and future directions of COPD self-management, a group of interested researchers and physicians, all of whom had previously published on this subject and who had previously collaborated on other projects, convened a workshop.
View Article and Find Full Text PDFBackground: Pulmonary rehabilitation has been shown to be effective for improving quality of life and function in patients with chronic obstructive pulmonary disease (COPD) but has not been studied extensively in homebound patients. Furthermore, little is known about the effectiveness of specific types of home-based interventions.
Purpose: The purpose of this study was to examine the effectiveness of in-home rehabilitation programs for individuals with COPD considered homebound according to Medicare definition and to compare outcomes of 2 different rehabilitation interventions.
Purpose: Geographic disparities in hospitalization rates for chronic obstructive pulmonary disease (COPD) have been observed in Texas. However, little is known about the sources of these variations. The purpose of this manuscript is to further explore the geographic disparity of COPD hospitalization rates in Texas by examining county-level factors affecting access to care.
View Article and Find Full Text PDFBackground: Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality caused by cigarette smoking and other environmental exposures. While variation in exposures may affect COPD morbidity and mortality, little is known about geographic variation, a surrogate of exposures. The objective of this manuscript is to explore the geographic variation in COPD hospitalization rates among the Texas population in 2006.
