Rationale: Work-related asthma (WRA) has been estimated to account for 15-20% of adult asthma cases. Studies have indicated that a substantial number of asthma patients have inadequate knowledge of work-related effects on their disease, which may contribute to suboptimal asthma control. A Canadian web-based educational tool on WRA was developed to address this knowledge gap in the population. This study evaluates the effectiveness of this tool.

Methods: Participants were recruited prior to a routine visit at a tertiary care asthma clinic at a Toronto Hospital. A brief WRA knowledge questionnaire was developed and administered immediately before and after use of the web-based educational tool.

Results: The study sample (N = 34) was mostly female (68%) with a mean age of 50.7 (SD, 17.2). Participants demonstrated significant improvement in questionnaire scores following interaction with the tool. The mean score increased from 76% (SEM = 2.1) to 84% (SEM = 1.7) (p = 0.001). On average, scores improved on 12 of the 13 questionnaire items. A 1-year follow-up of a sample of 19 participants demonstrated a slight reduction in mean scores, from 86% (SEM = 1.9) to 84% (SEM = 1.9), but still demonstrated a trend towards a higher score than the baseline (78%; SEM = 2.9; p = 0.09)

Conclusions: Our findings suggest that the educational tool has a positive effect on WRA knowledge, and that most knowledge is retained long-term. Future studies are needed in non-tertiary care clinic populations which may possess less baseline knowledge of WRA.
