Asthma, Chronic Obstructive Pulmonary Disease, Inhaler Devices, Knowledge, Skills

Respiratory disorders, such as asthma and chronic obstructive pulmonary disease (COPD), are major global causes of morbidity and mortality. Their management relies on medications like bronchodilators and corticosteroids, inhaled pharmaceutical preparations are essential routes of drug administration, and correct inhaler use is a crucial step for treatment effectiveness. Improper inhaler techniques can influence drug delivery to the lung and lead to treatment plan failure and worse disease outcomes. This study aims to evaluate the use of inhaler technique device skills in bronchial asthma and COPD adult patients and assess their knowledge and awareness about inhaler device use at the respiratory department of the University of Tripoli Hospital and Abu Sitta Hospital for Chest Diseases. A cross-sectional study was conducted from October to December 2024 at the University of Tripoli and Abu Sitta Hospitals in Tripoli-Libya. Data were collected from 200 patients using surveys, outpatient records, and direct interviews. Statistical analysis was performed using Excel. A notable percentage of patients (around 48%) who did not consistently rinse their mouths are at higher risk of suffering the previous side effects, most patients demonstrated a good technique for critical inhaler device steps However, a notable proportion of patients (around 15–25% across various steps) display inconsistent practices. Additionally, 6–13% of patients are entirely unaware of certain steps, reflecting an important area for education. While many patients demonstrate proper technique, there are clear gaps in knowledge and practice about inhaler device use, particularly in device maintenance, patient knowledge, skills, and spacer use. Enhanced pharmacist involvement, continuing educational programs, and the use of technology could substantially improve outcomes.
