Abstract


BACKGROUND AND AIM: Noncompliance with inhaler treatment among patients with asthma or chronic obstructive pulmonary disease (COPD) remains high worldwide. This study aims to identify issues related to inhaler use and to propose potential solutions.

METHODS: Patients aged 18 and older who had been receiving inhaler therapy for at least one year for asthma or COPD were included. The study was conducted across nine centers located in different geographical regions of Türkiye. Data were collected through face-to-face interviews, during which patients were asked about their demographic characteristics and history of inhalation therapy.

RESULTS: A total of 256 patients, 179 (69.92%) male and 77 female (30.08%), from 44 different cities were included in the study. Among the participants, 54.40% were former smokers, and 17.92% were current smokers. Annual physician visit rates were three or more times in 55.73% of patients, twice in 24.77%, and once in 13.62%; additionally, 5.88% reported not attending any check-up visits. The hospitalization rate in the past year was 28.53%. Among those hospitalized, 46.07% were admitted once, 30.34% twice, and 23.59% three times or more. The mean number of hospitalizations during the previous year was 2.27. Participants reported that education on inhaler device use was provided by physicians (83.50%), pharmacists (10.36%), and nurses (2.27%). Regarding the method of education, 77.52% received only verbal instructions, 20.13% received verbal instructions along with a demonstration using a similar device, and 2.35% were trained using a brochure. Among the patients, 45.43% stated that device usage was not tested during outpatient visits, while 40.20% reported at least one change in their inhaler device.

CONCLUSIONS: Although most patients stated that their initial education on device use was adequate, significant issues with noncompliance remain. These issues include providing only verbal inhaler device training and failing to assess patients' inhaler technique during outpatient visits. Training respiratory nurses specifically for inhaler device education, as well as certifying family medicine specialists and nurses working in family health centers on this topic, may help minimize these problems.
