PurposeOral corticosteroids (OCS) are an effective treatment for severe uncontrolled asthma or asthma exacerbations, but frequent bursts or long-term use carry serious and sometimes irreversible adverse effects, or complications such as adrenal insufficiency upon discontinuation. Our aim was to survey people with asthma on their experiences of, and attitudes towards, using OCS.Patients And MethodsThis study was a national descriptive cross-sectional survey of people with asthma in Australia. An anonymous survey was hosted online with invitations to participate distributed by national consumer peak bodies. Survey free-text responses were coded to the Theoretical Domains Framework (TDF) to elicit determinants of OCS use.Results1808 people with asthma participated between 3 and 16 May 2022. Most common reasons for using OCS were severe asthma symptoms (40%), doctor prescription (38%) or asthma action plan recommendations (20%). Approximately 55% of people had experienced adverse effects from OCS use. Commonly reported adverse effects were trouble sleeping (69%), weight gain (56%) and mood problems (41%). Of people who had OCS at home or an OCS script, 44% did not have an action plan that described when and how they should take them. People (33%) did not feel well informed about OCS adverse effects from their healthcare team. People had varied awareness (3-65%) of current available strategies to reduce OCS use. 'Knowledge', 'Environmental context and resources' and 'Social influences' were the most coded TDF domains influencing OCS use.ConclusionAdverse effects of OCS use are common. People with asthma are not adequately informed about optimal OCS use or strategies to reduce overuse. These findings can help guide the implementation of OCS stewardship initiatives.© 2025 Jones et al.
