AIM: Inappropriate inhaler use techniques lead to inadequate therapy and increased cost. The aim of the present study was to evaluate the asthma patients who applied to our outpatient clinic and proposed inhaler treatment regarding compliance of the treatment, inhaler use, preferences of devices and teaching how to use.MATERIAL-METHOD: A total number of 83 patients with asthma (13 male vs 70 female) who applied to our outpatient clinic, were included in the study. The patients were evaluated with a 10-step scoring system. After basal scoring, correct use of the devices were described individually and their using techniques were scored (score 2). Correct techniques are shown with video and rescored (score 3).RESULTS: Mean age of the patients were 50.8±11.9 and 63 (75.9%) of these were receiving regular therapy. Fifty one cases were using metered dose inhaler (MDI), 24 taking turbuhaler, 18 using discus and 9 taking aerolizer. Ninety four percent of the patients were satisfied with their devices and the main reasons of satisfactions were the device?s ease to use (70%) and ease to carriage (51%).The best mean basal score was found to be 8.72 in the patient group using discus. Among the scores obtained from first step education; MDI, turbuhaler, discus and aerolizer there were statistically significant difference when compared to initial ability scores ( p= 0.000, 0.000, 0.001, 0.011, respectively). There were also significant differences in scores after video-show except for discus use( p=0.000, 0.000, 0.034, 0.180, respectively). There was no difference between groups regarding inhaler treatment time, age and education.CONCLUSIONS: It is concluded that both individual training and video-assisted training for inhaler device use is beneficial in all ages, education-levels and disease stage.
