RESPIRATORY DISEASE
Spirometry provides valuable information for the diagnosis of respiratory diseases and has been proposed as an instrument to encourage smokers to quit [Some studies conducted in primary care propose a similar objective but present methodological differences, which might explain discordant results. In the first, Parkes et al. concluded that an intervention based on explaining spirometry results, compared to not doing so, was effective in increasing the abstinence rate after 12 months (On the other hand, Kotz et al. evaluated the effectiveness of a more complex and multi-component intervention that included different strategies for smoking cessation [The SPIROTAB study evaluated 350 smokers who were initially given spirometry and detailed information about the results as well as brief advice [Finally, our research group published the ESPITAP study [In short, while these previous studies allowed for evaluating the potential impact of a spirometry-based intervention to increase tobacco abstinence, our present study is the first to provide data on the independent motivational effectiveness of performing spirometry compared to not doing it.
