Objectives: The large number of available medicines and devices makes it almost impossible to have sufficient knowledge of each individual medicine and device, especially for general practitioners. Reducing the number of medicines and devices, based on rational criteria, allows physicians and pharmacists to build experience with a more limited set of medicines and to standardise the inhalation instructions.

Methods: In this study inhalers are compared by means of the SOJA method. The following selection criteria were applied: uniformity in device, number of steps per inhalation, risk of errors, hygienic aspects, feedback mechanism, risk of inhalation with an empty inhaler.

Results: Substantial differences were seen in the overall scores, with the Turbuhaler device showing the highest score, followed by Nexthaler and Spiromax. Several devices require more or less identical techniques, such as Diskus and its “generics”: Dry powder inhaler Glenmark or the Neutec have been scored separately, resulting in a much lower score than the Diskus, because only the LABA/ICS combination is available in these devices, without an option of rescue therapy in the same device.

Conclusions: A substantial reduction of inhalers, combined with optimal and standardised instructions should improve the care of asthma patients.
