Observational Study to Evaluate the Correctness of the Use of Inhaler Device in Patients With Asthma or Chronic Obstruct

Study Overview
=================
Brief Summary
-----------------
The correct use of inhalation devices is an inclusion criterion for all studies comparing inhaled treatments. In real life, however, patients may make many errors with their usual inhalation device, which may negate the benefits observed in clinical trials. In real life, many errors seem to be made, but no wide-scale evaluation has been performed. The correct use of inhalation devices is essential to ensure the effectiveness of the treatment. It has been recently demonstrated that inhaler misuse is associated with decreased asthma control in asthmatics treated with an inhaled corticosteroid. The aim of our observational study was to evaluate the inhaler device usage in patients with asthma or chronic obstructive pulmonary disease (COPD).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Investigator's evaluation of the correctness of patients' usage of inhaler device in patients with asthma or COPD assesses by investigator/pulmonologist |  | 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Global assessment of disease control, done by investigator. Investigator will globally assess the disease control by one on three categories: 'fully controlled', 'partially controlled', 'uncontrolled'. |  | 12 weeks | 
| Evaluation of patients' perception of the inhaler device and their perspective of symptom control and impact on daily life, by using the patient's questionnaire |  | 12 weeks | 
| Evaluation of the influence of practical education of the patients (performed by physician and/or nursing staff) on all above parameters/assessments |  | 12 weeks | 
| Collection of local demographics data in patients with asthma or COPD |  | 12 weeks |
