Most frequent errors in inhalation technique of patients with asthma treated at a tertiary care hospital.

Objective: To demonstrate the most frequent errors in inhalation technique in patients with asthma undergoing treatment at a tertiary care hospital.

Methods: A cross-sectional study with a convenience sample of asthma patients aged 18 years or over, treated at a pulmonology outpatient clinic of a tertiary care hospital. The assessment of inhalation technique of users of the dry powder inhalers Aerolizer®, Aerocaps and Diskus®, or metered-dose inhalers was based on the manufacturer's instructions for use of each inhaler device.

Incorrect use of inhalation devices among patients with bronchial asthma. A hospital-based cross-sectional study in Rio de Janeiro, Brazil.

Context And Objective: Treatment of asthma implies inhalation of specific drugs to reach high concentrations in the respiratory tree and ensure low drug bioavailability and few adverse effects. This study aimed to evaluate the effectiveness of the inhalation technique among outpatients with asthma.

Design And Setting: Tertiary-care hospital-based cross-sectional study in Rio de Janeiro.
