Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is an exploratory, qualitative study, investigating the personal experiences of people living with severe asthma. Interviews will be performed on a one-off basis. This will involve a video and audio recorded interview that will be conducted in their own home. Each interview would go for approximately 1-2 hours.
Using rigorous, systematic qualitative methods we will analyse transcripts from in-depth individual interviews, and use these data to publish in peer reviewed international journals. Also, part of our study will include developing a visual web-based information resource for use by the public (information and support) and health professionals (education/training). We are following the DIPEx methodology, that has been used for thousands of participants in the UK, several other countries, and has been used for six studies within Australia so far (on www.healthtalkaustralia.org).

Intervention assignment
Other design features
Phase
Type of endpoint/s
Statistical methods / analysis
In line with standard qualitative research practice we will use a maximum variation sampling framework, which is a purposive sample of approximately 30-50 people with severe refractory asthma, who will be recruited from different settings across Australia. Therefore, no formal sample calculations were performed. We aim for depth in our interviews and we will keep interviewing participants until no new themes have emerged.The methods used for this project are based on those established by the Health Experiences Research Group (HERG) at the University of Oxford and managed through the DIPEx UK Charity. We will use systematic and rigorous qualitative research methods and analysis, using a narrative illness methodology and thematic analysis.
