Onset and duration of action and ease of use were classified higher as important parameters to increase patients’ compliance, according to physicians’ perspectives reported in a study published in Pulmonology. To investigate the perspective of physicians treating chronic airway diseases on the importance of device and substance characteristics that influence the compliance of patients with chronic obstructive airways diseases, the study investigators distributed a structured questionnaire to 144 physicians, conducted personal interviews, and evaluated answers on a scale from 1 (most important influencing parameter) to 6 (least important). In line with the findings among patients in the above study, the most important parameter influencing patients’ compliance, according to physician’s perspectives, was rapid onset of action, followed by type of inhalation device and duration of action. Adverse events were considered the least important parameter by physicians. When COPD and asthma were examined separately, the most important parameters influencing compliance were rapid onset of action, ease of use, and duration of action, whereas rapid onset of action was significantly more important in asthma than in COPD.
