**Official Title:** Evaluation of Perception and Knowledge of Adherence to COPD Inhalation Therapy at Patient, GP and Pulmonologist Level

**NCT ID:** [NCT04246931](https://clinicaltrials.gov/study/NCT04246931)

## Key Facts

## Brief Summary

The rationale of this study is to have a better understanding of the perception of the pulmonologists, general practitioners and patients of adherence (causes, main consequences, supportive tools,..) and the use of TAI-questionnaire (appreciation, usability,…) by interviewing pulmonologists \& general practitioners and a survey with patients. Based on the outcome, projects and tools can be developed to help health care professionals to motivate patients to improve adherence and to help patients to increase their adherence to inhalation therapy.
