Summary
A study found that 19.5% of COPD patients inaccurately reported their smoking status. This deception rate was higher in women, highlighting the need for objective measures like cooximetry to accurately assess smoking in clinical practice.
Area of Science:
- Pulmonology
- Clinical Research
- Tobacco Cessation
Background:
- Accurate assessment of smoking status is crucial for managing Chronic Obstructive Pulmonary Disease (COPD).
- Self-reported smoking data may be unreliable, potentially impacting treatment efficacy.
- Objective measures are needed to validate patient-reported smoking habits.
Purpose of the Study:
- To determine the deception rate between patient interviews and cooximetry readings in COPD patients.
- To evaluate the concordance of smoking status reporting using clinical interviews versus objective cooximetry measurements.
- To identify factors associated with discrepancies in smoking status reporting among COPD patients.
Main Methods:
- A prospective observational study was conducted.
- 169 COPD patients were recruited from a monographic consultation.
- Smoking status was assessed via clinical interview and validated using carbon monoxide cooximetry.
Main Results:
- A smoking prevalence of 36.7% was identified.
- The overall deception rate was 19.5%, with 24.3% of self-reported non-smokers being deceptive.
- A higher deception rate was observed in women (31.8%) compared to men (15.2%), with no significant association with age, tobacco consumption, or FEV1.
Conclusions:
- A significant rate of deception exists regarding smoking status in COPD patients.
- Objective measures like cooximetry are essential for accurate smoking assessment in COPD management.
- Interventions to encourage smoking cessation should consider the higher deception rates observed in certain patient groups, particularly women.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

3.4K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
