OBJECTIVE: To examine the effect of brief disease-specific education delivered in primary care on objective measures of knowledge in individuals recently diagnosed with chronic obstructive pulmonary disease (COPD). METHODS: A randomized control trial was undertaken during which an experimental group received 2 h of education delivered by a certified COPD educator and a control group received usual care. The Bristol COPD Knowledge Questionnaire (BCKQ) was self-administered at the time of randomization and approximately three months later. RESULTS: Of the 93 individuals that completed the study, 50 (forced expiratory volume in 1s (FEV1) 60.0 +/- 14.3% predicted; 22 males) and 43 (FEV1 58.2 +/- 14.4% predicted; 20 males) participants were randomized to the experimental and control groups, respectively. The BCKQ increased from 27.6 +/- 8.7 to 36.5 +/- 7.7 points (p < 0.001) in the experimental group, which was greater than any seen in the control group (between-group difference 8.3, 95% confidence interval 5.5 to 11.2 points). CONCLUSION: As little as 2 h of education delivered in primary care was effective at increasing objective measures of disease-specific knowledge. PRACTICE IMPLICATIONS: A program of brief education delivered in the primary care setting, represents an important approach for many individuals with COPD who are unlikely to access pulmonary rehabilitation.
