Interchangeability of inhalation devices by pharmacist and its potential impact on asthma control and stabilization of COPD - a research project by Delphi method
Abstract
Objectives: The inhaled route is the first line administration method in the management of disease with chronic airways obstruction (asthma, COPD). This study aimed to effect of potential interchangeability of inhalation devices and theirs substitution by pharmacist on asthma and COPD control.
Methods: In this two-round Delphi survey, 10 experts in asthma and COPD (5 allergologists, 5 pulmonologists) completed a 11-item, internet-based (Survey Monkeys), self-administered questionnaire about the role and choice of inhalation devices, and theirs potential substitution. Results: Experts considered that the role of inhalation device was as important as that active substance and that is also important good manipulation with inhalation device by patient.
Experts considered that inhalation devices are into reliable scale interchangeable, but experts discouraged inhalation device interchangeability and switching (for example for cost reasons) by pharmacist without medical consultation. Conclusions: The interchangeability of inhalation devices and theirs substitution by pharmacist without medical consultation is not recommended by experts.
