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).

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

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Investigator's evaluation of the correctness of patients' usage of inhaler device in patients with asthma or COPD assesses by investigator/pulmonologist [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • 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'. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • 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 [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Evaluation of the influence of practical education of the patients (performed by physician and/or nursing staff) on all above parameters/assessments [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Collection of local demographics data in patients with asthma or COPD [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
