BackgroundIn patients with asthma, over-reliance and overuse of short-acting beta2 agonist (SABA) is common and associated with increased morbidity and mortality. Patient beliefs are a key driver of inappropriate reliever use. A recently developed, brief, online intervention has been shown to identify and shift patient beliefs that drive inappropriate reliever use. Whether this intervention works to shift beliefs in individuals with asthma when delivered by community pharmacists is unknown. ObjectiveTo investigate the feasibility and acceptability of a brief community pharmacist-delivered behavior change intervention, and its effect on beliefs about SABA and SABA use in patients with asthma. MethodsThis is a non-randomised, before- and after- study of 120 individuals aged 18 years and older, prescribed a SABA for their asthma symptoms, presenting to one of two enrolled community pharmacies in Auckland, New Zealand. At enrolment, all participants will complete the SABA Reliance Questionnaire (SRQ), Asthma Control Test and 5-item Medication Adherence Report Scale via an online survey platform. Control participants will receive usual asthma care from their community pharmacy. Intervention participants will receive the intervention to shift any misplaced beliefs about SABA, comprising the SRQ to identify individual beliefs about SABA, then personalized information and discussion between pharmacist and patient based on the specific responses to the questionnaires. Those on SABA monotherapy and/or are at risk of SABA overuse will be referred to the general practitioner. Effect on beliefs about SABA and actual SABA use will be assessed by the SRQ and dispensing records, respectively. Feasibility will be evaluated through participant recruitment and retention rates, intervention fidelity, appropriateness and procedures of outcome measures pre- and post-intervention, and acceptability by obtaining feedback from participants (both patients and pharmacists) on the intervention.

Introduction: Non-adherence to inhaled corticosteroids (ICS) in children with asthma leads to significant morbidity and mortality. Few interventions to improve adherence have been effective and little is known about what contributes to intervention effectiveness. This systematic review summarises the efficacy of these interventions and the characteristics of effective interventions to inform future studies aiming to improve adherence to ICS in children with asthma. Methods: PubMed, Embase, PsychINFO, Medline, Web of Science, and International Pharmaceutical Abstracts were systematically searched on the 3rd of October 2020 for randomised control trials measuring adherence to ICS in children with asthma. A narrative synthesis was conducted focusing on intervention efficacy and study reliability. Intervention content was coded based on the NICE guidelines for medicines adherence (The Perceptions and Practicalities Approach, PAPA) and Behaviour Change Techniques (BCT), to determine the effective aspects of the intervention. Results: Of 240 studies identified, 25 were eligible for inclusion. Thirteen of the twenty-five studies were categorised as being highly reliable. Nine of the thirteen studies were effective at increasing adherence and six of those met the criteria for a PAPA intervention. Conclusion: Adherence interventions in children with asthma have mixed effectiveness. Effective studies tended to be of higher quality, were tailored to individuals perceptual and practical adherence barriers, and used multiple BCTs. However, due to the small number of included studies and varying study design quality, conclusions drawn here are preliminary. Future research is needed to test a PAPA-based intervention with a rigorous study design as outlined in this review
