Nurses' Reports of Inhaler Use Errors in Patients with Chronic Obstructive Pulmonary Disease in Hong Kong.

Background: Persistently high rates of inhaler errors and poor adherence among Chronic Obstructive Pulmonary Disease (COPD) patients contribute to ineffective symptomatic control, high care burdens, and increased healthcare resource utilization.

Objective: This study aimed to report (i) nurses-identified common problems and errors of inhaler use in COPD patients, (ii) nurses' attitudes, practices, training needs and required support in inhaler education.

Methods: An online questionnaire survey was conducted with nurses working in Hong Kong from May to June 2023 using an exponential, non-discriminative snowball sampling strategy.
