Comparison of spirometric thresholds in diagnosing smoking-related airflow obstruction: authors' response.
BACKGROUND Diagnosis of chronic obstructive pulmonary disease is based on detection of airflow obstruction on spirometry. There is no consensus regarding using a fixed threshold to define airflow obstruction versus using the lower limit of normal (LLN) adjusted for age. We compared the accuracy and discrimination of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommended f...
متن کاملThe Relationship between the Severity of Airway Obstruction and COPD Diagnostic Questionnaire Score in COPD Patients
Background & objectives: Chronic obstructive pulmonary disease (COPD) is characterized by irreversible airflow limitation and systemic inflammation which is also associated with pulmonary and extra-pulmonary complications. COPD Diagnostic Questionnaire (CDQ) is a valid questionnaire that is used to identify patients with COPD. The purpose of this study was to determine the relationship between ...
متن کاملSpirometric predictors of lung function decline and mortality in early chronic obstructive pulmonary disease.
RATIONALE The course of lung function decline for smokers with early airflow obstruction remains undefined. It is also unclear which early spirometric characteristics identify individuals at risk for rapid decline and increased mortality. OBJECTIVES To determine the association between spirometric measures and 5-year decline in FEV(1) and 12-year mortality. METHODS We analyzed longitudinal ...
متن کاملSpirometric obstruction and tobacco exposure among male Turkish nursing home residents.
Spirometric obstruction is a prevalent problem in older adults and related to life-style risk factors. Symptoms related to chronic-obstructive-pulmonary-disease (COPD) are also prevalent symptoms with diverse etiologies - not limited to pulmonary obstruction. Older adults may have unrecognized airway obstruction due to functional limitations or symptoms mis-attributed to age/other co-morbiditie...
متن کاملEstimating population prevalence of potential airflow obstruction using different spirometric criteria: a pooled cross-sectional analysis of persons aged 40–95 years in England and Wales
OBJECTIVES Consistent estimation of the burden of chronic obstructive pulmonary disease (COPD) has been hindered by differences in methods, including different spirometric cut-offs for impaired lung function. The impact of different definitions on the prevalence of potential airflow obstruction, and its associations with key risk factors, is evaluated using cross-sectional data from two nationa...
