Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a non-randomised, before-after, study. The first 30 participants at each pharmacy will be allocated to control, the following 30 participants will receive the intervention.

The intervention will include three components:
1. Delivery of targeted, standardised information, based on responses to the SABA reliance questionnaire (SRQ). This will be administered online via a weblink while the participant is at the pharmacy;
2. Personalised discussion between the pharmacist and participant based on the specific responses to the study questionnaires (conducted by the pharmacist after the online component) and
3. Referral to general practitioner (GP) for those at risk of SABA overuse.

The standardised information helps patients understand what their SRQ responses might mean for them. The aim of this information is to raise awareness of the problem of SABA overuse and provides advice about the correct use of SABA inhalers. This information will be provided directly to the patient on their personal device.

To complement the standardised messages, the pharmacist will have an in-person, brief discussion (expected to be less than 5 minutes) with the participant regarding their responses to the SRQ. The SRQ will provide the participant with a score between 4 and 20. A score of 12 or more indicates the participant holds beliefs that may lead them to over rely on SABA. For these participants, the pharmacist will give behaviour-change messages verbally along with written information to shift beliefs, based on the specific responses to each statement in the SRQ. For participants with scores of less than 12 on the SRQ, the pharmacists will provide messages that reinforce and strengthen the current beliefs about SABA.

The standardised information and information provided by the pharmacist has been designed specifically for the study, based on previous work conducted by the research group.

Finally, all participants who indicate they are not using a preventer or report they are using SABA more than twice a week will be categorised as at risk of SABA overuse and will be referred to their GP. Pharmacists will also discuss this with the participant and urge the patient to have a discussion with their GP about their answers to the questionnaire and potential for preventer treatment.

The project coordinator will shadow the pharmacist in 10% of the sample (with participant permission) to check for intervention fidelity.

Behaviour
Comparator / control treatment
Control group will receive usual care from their community pharmacy. This will involve provision of standardised educational material on asthma, known as an 'asthma self care fact card'. This is a readily available resource in New Zealand community pharmacies provided by the Pharmaceutical Society of New Zealand (https://www.psnz.org.nz). This will be provided to all control participants. The pharmacist may or may not discuss their reliever use with the participant (not prompted by study).

Outcomes
Primary outcome [1] 325369 0
Recruitment and retention rates of participants in control and intervention groups. Recruitment and retention rates will be estimated through recording the number of participants invited to participate in the intervention by the pharmacist, number of participants who view the study URL but do not enter the study, number of participants recruited online and via the pharmacist and number of participants retained at the 30 days and 90 days follow-up. Reasons for exclusion will also be recorded. These outcomes will be analysed by accessing the survey website analytics.

Eligibility
Key inclusion criteria
Individuals presenting to one of the two enrolled community pharmacies will be eligible to participate in the study if they meet the following eligibility criteria:
- Aged 18 years or over
- Prescribed a short acting beta agonist (SABA) as a ‘reliever’ for their asthma symptoms.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Individuals will not be eligible to participate if they are using a SABA for a reason other than asthma (e.g. viral respiratory infection, exercise-induced asthma), do not manage their own medicines or anticipate changes to their medicines within the next 90 days (i.e. are following a step up/down medication management approach).

Other design features
This is a before-and-after study in which the control group will be recruited followed by the intervention group. This design was chosen to minimise the effect of the intervention provided by the pharmacist crossing over to the control group.

Type of endpoint/s
Efficacy
Statistical methods / analysis
Descriptive statistics will be used to evaluate feasibility and acceptability for quantitative data; thematic analysis using a general inductive approach will be used for qualitative data. Changes in beliefs and inhaler use between the groups will be analysed using an independent samples t-test. A generalized linear mixed model will be used to determine the effect of patient/pharmacy characteristics on measured outcomes.
