The validity of using ICD-9 codes and pharmacy records to identify patients with chronic obstructive pulmonary disease

Background  

Administrative data is often used to identify patients with chronic obstructive pulmonary disease (COPD), yet the validity of this approach is unclear. We sought to develop a predictive model utilizing administrative data to accurately identify patients with COPD.     

Identifying and characterizing COPD patients in US managed care. A retrospective,cross-sectional analysis of administrative claims data

Background  

Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death among US adults and is projected to be the third by 2020. In anticipation of the increasing burden imposed on healthcare systems and payers by patients with COPD, a means of identifying COPD patients who incur higher healthcare utilization and costs is needed.     

Development and validation of the living with chronic obstructive pulmonary disease questionnaire

Purpose  

Available patient-reported outcome (PRO) measures for chronic obstructive pulmonary disease (COPD) focus primarily on impairment (symptoms) and activities (functioning). The purpose of the study was to develop a patient-based PRO measure for COPD that captures the overall everyday impact of living with COPD from the patient’s perspective.     

The UK Quality and Outcomes Framework pay-for-performance scheme and spirometry: rewarding quality or just quantity? A cross-sectional study in Rotherham, UK

Background  

Accurate spirometry is important in the management of COPD. The UK Quality and Outcomes Framework pay-for-performance scheme for general practitioners includes spirometry related indicators within its COPD domain. It is not known whether high achievement against QOF spirometry indicators is associated with spirometry to BTS standards.     

Model for estimating the population prevalence of chronic obstructive pulmonary disease: cross sectional data from the Health Survey for England

Background  

Chronic obstructive pulmonary disease (COPD) is a major but neglected public health problem. Currently 1.4% of the England population has a clinical diagnosis of COPD, but the true burden of the disease has not been known with certainty, as many cases remain undiagnosed.     

Validation of a Spanish version of the airways questionnaire 20: a short and simple instrument

Objective  

To describe the psychometric properties of the Spanish version of the Airways Questionnaire 20 (AQ20S) for asthma and COPD separately.     

What determines subjective health status in patients with chronic obstructive pulmonary disease: importance of symptoms in subjective health status of COPD patients

Background  

Subjective health status is the result of an interaction between physiological and psychosocial factors in patients with chronic obstructive pulmonary disease (COPD). However, there is little understanding of multivariate explanations of subjective health status in COPD. The purpose of this study was to explore what determines subjective health status in COPD by evaluating the relationships between background variables such as age and sex, predicted FEV₁%, oxygen saturation, breathlessness, anxiety and depression, exercise capacity, and physical and mental health.     

Effect of exacerbations on health status in subjects with chronic obstructive pulmonary disease

Background  

Acute exacerbations may cause deteriorations in the health status of subjects with chronic obstructive pulmonary disease (COPD). The present study prospectively evaluated the effects of such exacerbations on the health status and pulmonary function of subjects with COPD over a 6-month period, and examined whether those subjects showed a steeper decline in their health status versus those subjects without exacerbations.     

Development,validity and responsiveness of the Clinical COPD Questionnaire

Background  

The new Global Obstructive Lung Disease (GOLD) guidelines advice to focus treatment in Chronic Obstructive Pulmonary Disease (COPD) on improvement of functional state, prevention of disease progression and minimization of symptoms. So far no validated questionnaires are available to measure symptom and functional state in daily clinical practice. The aim of this study was to develop and validate the Clinical COPD Questionnaire (CCQ).     

Validation of the respiratory toxics exposure score (RTES) for chronic obstructive pulmonary disease screening

Objective  

Our aim is to evaluate the validity of exhaled carbon monoxide (CO) and of a newly-created score as markers of Chronic Obstructive Pulmonary Disease (COPD).     

Effectiveness of a Tai chi Qigong program in promoting health-related quality of life and perceived social support in chronic obstructive pulmonary disease clients

Purpose  

This paper evaluates the effectiveness of a 3-month Tai chi Qigong (TCQ) program in promoting the psychosocial functional health of clients with chronic obstructive pulmonary disease (COPD) in Hong Kong.     

Early detection of COPD in primary care -The Copenhagen COPD Screening Project

Background  

Chronic Obstructive Pulmonary Disease (COPD) is among the leading causes of death in the world, and further increases in the prevalence and mortality are predicted. Delay in diagnosing COPD appears frequently even though current consensus guidelines emphasize the importance of early detection of the disease. The aim of the present study is to evaluate the effectiveness of a screening programme in general practice.     

Validation of the Clinical COPD questionnaire in Italian language

Background  

The development and validation study of the Clinical Chronic Obstructive Disease (COPD) Questionnaire (CCQ) has recently been published in this journal. The CCQ is the first questionnaire that incorporates both clinician and patient guideline goals in the clinical control evaluation of patients with COPD in general clinical practice. The aim of this study is the validation of the CCQ questionnaire in Italian, in specific pulmonary disease clinical practice.     

Comparison between the disease-specific Airways Questionnaire 20 and the generic 15D instruments in COPD

Background  

Given that the assessment of health-related quality of life (HRQoL) is an essential outcome measure to optimize chronic obstructive pulmonary disease (COPD) patient management, there is a need for a short and fast, reliable and valid instrument for routine use in clinical practice. The objective of this study was to analyse the relationship between the disease-specific Airways questionnaire (AQ20) and the generic 15D health-related quality of life (HRQoL) instrument simultaneously in a large cohort of patients with COPD. We also compare the HRQoL of COPD patients with that of the general population.     

HIV and COPD: impact of risk behaviors and diseases on quality of life

Purpose  

Smoking worsens quality of life among HIV-infected individuals, but it remains unclear if this association is related simply to smoking or to chronic obstructive pulmonary disease (COPD), the end-organ disease caused by smoking.     

The experience of using the SEIQoL-DW with patients with advanced chronic obstructive pulmonary disease (COPD): issues of process and outcome

Purpose  

To report the experience of using the SEIQoL-DW for the measurement of quality of life with patients with advanced COPD and consider its feasibility, acceptability and appropriateness for a Phase III randomised controlled trial (RCT).     

The health impact of remarriage behavior on chronic obstructive pulmonary disease: findings from the US longitudinal survey

Background  

Chronic obstructive pulmonary disease (COPD) is a major disease among adults, and its deterioration was reported to be associated with psychological imbalance. Meanwhile, bereavement and divorce have proven harmful to the health status of a surviving spouse. But few studies have been conducted to evaluate the remedial effect on survivors' health outcome by remarriage after bereavement. The present study thus examined the associations between remarriage and the onset of COPD.
