Cognitive impairment has high prevalence in older adults with airway diseases, and may influence their competence in inhaler use, thereby negatively affecting patient prognosis. We aimed to evaluate the relationship between cognitive function and competence in inhaler technique. We enrolled 108 inhaler naïve older adults (≥60 years) with airway disease in this prospective observational study and performed the Korean version of the Mini-Mental State Examination (K-MMSE). After explaining the inhaler technique, we scored its competence. While the total K-MMSE score was unrelated to the inhaler score, the orientation for place (estimates=0.62, p = 0.009), registration (estimates=0.988, p = 0.037), and recall (estimates=0.161, p = 0.048) were positively associated with the score. Low K-MMSE scores were associated with lower odds ratio for the competence of the “exhale” step (adjusted odds ratio= 0.23, p = 0.018). Thus, a K-MMSE-mediated evaluation of cognitive function in older adults with airway disease can be a useful tool to predict inhaler competence.
