Multicenter Study Comparative Study Observational StudyUsage and usability of one dry powder inhaler compared to other inhalers at therapy start: an open, non-interventional observational study in Poland and Germany.
Inhalation is the preferred route of drug administration for patients with asthma or COPD. It is generally predicted that there is a high error rate in inhaler usage, especially at the therapy start. The primary objective of this study was the validation of a questionnaire that can be used for assessing a successful inhalation technique, patient satisfaction as well as the compliance in daily practice.The secondary objective was to examine the "real-life" usage of one inhalation device in comparison with other devices at the start of the therapy. ⋯ The results of this study show that investigators found EH easy to teach, the patients found it easy to use and their satisfaction with the device was high in comparison to other inhalation devices. Thus EH can be matched to many patients already at the therapy start. In addition, the high consistency of the received data and large association of the assessment of the inhaler usage and the general assessment of the inhaler indicate that the used questionnaires were appropriate tools to examine usage and usability of inhaler devices in adult patients and children.
