Objective Assessment of Adherence to Inhalers by COPD Patients

July 22, 2019 updated by: Professor Richard Costello, Beaumont Hospital

Rationale: Objective adherence to inhaled therapy by patients with chronic obstructive pulmonary disease (COPD) has not been reported.

Objectives: To objectively quantify adherence to preventer Diskus inhaler therapy by patients with COPD with an electronic audio recording device (INCA).

Methods: This was a prospective observational study. On discharge from hospital patients were given a salmeterol/fluticasone inhaler with an INCA device attached. Analysis of this audio quantified the frequency and proficiency of inhaler use.
