A non-probabilistic sample of 80 adult participants was calculated, and the inhalation technique was evaluated (depending on the device used) using a scale validated for Colombia. Descriptive analysis of the qualitative variables was performed using frequencies and percentages. The Chi-Square test and Fisher’s exact test (in corresponding cases) were used to look for association relationships between categorical variables.Results: A total of 80 participants were evaluated, of which 66.3% (n = 53) were male, and 32.5% were older than 80 years. Clinically, 30.0% (n = 24) were classified as Modified Medical Research Council Dyspnea Scale (mMRC) grade 3, and 51.2% (n = 41) had at least one exacerbation per year. The main comorbidity was hypertension (40.3%). Pressurized metered-dose inhalers with spacer were the most used device at 22.7% (n = 39). Incorrect technique (at least one error in the steps of the inhalation technique used) was found in 48.7%. The most frequent error among all the techniques was the failure to perform pre-inspiratory exhalation. No significant differences were observed between the development of the technique and the characteristics of the participants.Conclusion: Nearly half of the patients who use inhalation devices make errors in the technique. Patient education and training of healthcare personnel represent a fundamental pillar in mitigating the incorrect use of these devices.Keywords: pulmonary disease, chronic obstructive, administration, inhalation, medication errors
