Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Has not previously received a diagnosis from a doctor of asthma
Has co-existing lung condition e.g. COPD

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will have phoned the AFNSW Infoline service. Following the usual Infoline service the phone counsellor will inform the potential participant that AFNSW is conducting a study. Brief verbal information may then be provided regarding the study and if interested a four question eligibility screening will be asked. The four questions are: are you over 18 years of age? ; have you been diagnosed with asthma by a doctor? ; do you currently take an asthma preventer inhaler? ; have you been diagnosed with another lung condition?

If the potential participant is eligible and interested then their contact details will be collected and an email or letter will be sent containing the Patient Information Statement (PIS) and Patient Consent Form (PCF). A reminder follow up call will be made after one week.

Participants will be allocated to either intervention or control group by the Infoline service counsellor. The participant will not be told which group they are in.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Allocation will occur at the level of the telephone call. Each alternate call will be allocated to the intervention group.

Statistical methods / analysis
Quantitative outcome data will be analysed using parametric and non-parametric statistical methods to determine any differences in outcome measures of the intervention compared to control groups.
Qualitative data from post-service participant and telephone counsellor interviews will be content analysed for emergent and anticipated themes, following transcription of audio recorded interviews.
Sample size: Based on a power calculation (alpha level= 0.05; 80% power), N =180 (90 intervention and 90 control)
