[Purpose] The present study surveyed inhaler technique education and evaluated the relationship between inhalation errors and instruction methods. [Participants and Methods] This was a cross-sectional study involving 48 subjects undergoing inhalation therapy. A questionnaire administered by an interviewer was used to survey the number of times inhalation instruction had been given, whether or not there was instruction by demonstration, the occupation of the inhalation instructor, the inhalation drugs used, the number of past experiences with inhalers, and the perceived efficacy of the inhalation drugs, to assess the relationship between inhalation errors and instruction methods. [Results] 54.2% of patients had been given instructions by demonstration. Instruction by demonstration was a significantly more multidisciplinary approach and patients of this group received instruction more times than the instruction without demonstration group. The group that had been given inhalation instruction more than once showed a significant reduction in inhalation errors compared to the group given instruction only once. The number of occupations involved in giving instruction and inhalation errors were not significantly related. [Conclusion] Multiple rounds of inhalation instruction reduces inhalation error; however, methods of inhalation instruction with a multidisciplinary approach need to be studied further.
