Why was it done?
Chronic Obstructive Pulmonary Disease (COPD) and asthma represent a significant public health issue. Medications are administered using inhaler devices (ID) that require prior demonstration to ensure their proper use. Incorrect usage of inhaler devices might have a major influence on the clinical effectiveness of the delivered drug.
What was done?
The goal of our study was to detect potential errors in the manipulation of inhaler devices (ID) and to provide patients with appropriate information on their correct use in order to improve medication management.
How was it done?
For this study, every hospitalised adult patient with an ongoing treatment with ID underwent a pharmaceutical interview during their hospitalisation.
This interview was done using a questionnaire assessing the patient’s knowledge of their medications and a 12-items evaluation grid covering every step of proper inhalation technique.
What has been achieved?
Between June and August 2023, 27 patients were interviewed: the average age was 73 years. 34 ID manipulations were observed. Dry powder inhalers were the most prescribed DIs (68%), followed by pressurized metered dose inhalers (23%) and soft mist inhaler (9%). For 10 DIs (29%), no explanation was given to the patient. Furthermore, inhaler technique instructions were provided by a pulmonologist (65%), general practitioner (23%), pharmacist (4%), nurse (4%) and therapeutic education program (4%). The interviews revealed that 71% of patients were not familiar with the prescribed molecules or their mechanism of action. Out of the 34 DI manipulations, only 15% were performed perfectly, and 27% were not executed properly. The steps of deep exhalation before inhalation and breath-holding after inhalation were not performed in 70% and 62% of observations, respectively. Finally, 50% of patients did not rinse their mouths after using inhaled corticosteroids.
What next?
This study has highlighted the improper use of DIs, which can lead to a loss of therapeutic effectiveness. Therefore, we have developed 9 information booklets on the correct use of the DIs that describe different handling procedures for proper inhalation. These booklets are provided at the end of the interview. Educating patients on the proper use of these inhalation devices during the initial prescription or dispensing should lead to an overall improvement in patient care.
