Turbutest™ in the training of asthmatic Turbuhaler™ users

Background: Correct utilization of inhalation devices is a key factor in asthma management. Objective assessment of the ability to use inhaler devices is therefore fundamental. Methods: The objective was to assess objectively the inhalation technique of Turbuhaler(TM) users who reported having no difficulty in using such a device. A total of 600 asthmatic patients of our allergology outpatient department, daily users of Turbuhaler devices, were evaluated with Turbutest(TM). This is a simple portable apparatus which connects a Turbuhaler inhaler with an electronic device to allow semiquantitative assessment of inhalation technique, with a score ranging from 0 (worst) to 3 (best), readily visualized on the apparatus. Patients were allowed to practice with Turbutest, assisted by an allergologist, until they improved their scores. A second Turbutest assessment was performed at a 2-month follow-up visit. Results: On the first assessment, one-third of the patients had scores inadequate to allow a good inhalation, and only 20% achieved a score of 3. On the second assessment, significantly higher Turbutest scores were observed. Conclusions: Turbutest is a valuable tool in asthmatic patients' training, allowing identification and improvement of an inadequate inhalation technique with Turbuhaler.
