Background: This study aimed to determine the associations of various sociodemographic factors with the level of disease-specific knowledge among Hong Kong Chinese patients with COPD.
Methods: A cross-sectional survey of 100 Chinese adults with COPD recruited from outpatient clinics was conducted from September 2009 to September 2010. Data on the knowledge specific to COPD and patients’ sociodemographics were collected from face-to-face interviews. Primary outcome of disease-specific knowledge was measured using 65-item Bristol COPD Knowledge Questionnaire (BCKQ), summing up the 65 items as the BCKQ overall score. Associations of sociodemographic factors with the BCKQ overall score were evaluated using the linear regression model.
Results: The mean BCKQ overall score of our patients was 41.01 (SD: 10.64). The knowledge in topics of “Smoking” and “Phlegm” achieved the first (3.97, SD: 0.82) and second (3.91, SD: 1.17) highest mean scores, respectively, while the topic of “Oral steroids” returned the lowest mean score of 1.89 (SD: 1.64). The BCKQ overall score progressively declined (P<0.001) with increase in education level, with the highest BCKQ overall score of 46.71 at no formal education among all subgroups. Compared to nondrinkers, current drinkers were associated with lower total BCKQ score.
Conclusion: We found that among COPD patients in outpatient clinics, impairments in the level of COPD knowledge were evident in patients who were current drinkers or had higher level of education.
