Turbutest in the training of asthmatic Turbuhaler users.

Abstract

Correct utilization of inhalation devices is a key factor in asthma management. Objective assessment of the ability to use inhaler devices is therefore fundamental. The objective was to assess objectively the inhalation technique of Turbuhaler 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. 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. 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. Turbutest is a valuable tool in asthmatic patients' training, allowing identification and improvement of an inadequate inhalation technique with Turbuhaler.
