Primary Outcome
Comparison of reliability of assessment of inhalation technique by checklist method in patients with asthma and COPD,Comparison of reliability of assessment of inhalation technique by 4 grade scale in patients with asthma and COPD,Comparison of validity of assessment of inhalation technique by checklist method in patients with asthma and COPD,Comparison of validity of assessment of inhalation technique by 4 grade scale in patients with asthma and COPD,Comparison of validity of assessment of inhalation technique by Vitalograph®AIM in patients with asthma and COPD
Summary
A significant percentage of patients with asthma and COPD do not use their inhalers properly.
 Experts recommend that in patients with obstructive lung diseases, inhalation technique and
 patient adherence should be evaluated at every visit. The assessment of inhalation skills
 depends on the method of evaluation. There are few different methods of assessment of
 inhalation technique, however none of them is recommended as the most accurate.
 
 Therefore, the aim of the study is:
 
 1. to compare three different methods of assessment of inhalation technique in patients
 with asthma and COPD.
 
 These methods include:
 
 1. Checklist of mistakes in inhalation technique (including critical mistakes)
 
 2. 4 grade scale of inhalation technique
 
 3. Assessment by Vitalograph®AIM (Aerosol Inhaling Monitor)
 
 2. to analyze the influence of Vitalograph®AIM based inhalation technique training on
 inhalation skills
 
 One hundred and thirty patients with asthma or COPD, who use inhaled medication on a regular
 basis will be enrolled. Inhalation technique will be evaluated by two observers independently
 at the same time with all three methods (checklist, 4 grade scale, Vitalograph®AIM). To
 compare these methods, the investigators will analyze method reliability and validity.
 Additionally, inhalation technique will be evaluated 30 minutes after Vitalograph®AIM based
 training to analyze the potential benefit of its application in practicing inhalation skills.
