The objective was to evaluate the correctness of the inhalation technique in a nationwide sample of patients and medical personnel, in order to define targeted educational goals. A total of 1640 volunteers (746 patients, 466 nurses and 428 physicians) were evaluated. Only 9% of patients, 15% of nurses and 28% of physicians showed a correct inhalation technique. Physicians performed significantly better (mean score 77 ± 23) than nurses (71 ± 22) and patients (62 ± 26). Scores in general practitioners and pediatricians were significantly lower than those of chest physicians and allergists. In conclusion, proper use of metered dose inhalers (MDI) in patients and medical personnel is still faulty. Despite the physician's awareness of the importance of a correct inhalation technique in the use of MDI, this study shows severe deficiencies, showing the need for substantial changes in educational efforts, and particularly addressed to general practitioners.
