Description of intervention(s) / exposure
This study will examine the feasibility and logistics of undertaking a community pharmacist-led review of mild asthma, with the capacity to adjust participant Anti-Inflammatory Reliever (AIR) algorithm guidelines, known as AIR Therapy steps under a primary care physician standing order.
Participants will attend two visits to a study pharmacy at baseline and week 12 post-intervention commencement. The study will be conducted via face-to-face interaction between participants and community-pharmacist investigators with remote participant-reported outcomes collected in between study visits in electronic diaries.
Notes on Questionnaires:
The Asthma Control Measure (ACM) is a validated questionnaire used to assess asthma control over the past four weeks (1,2). This is a self-reported questionnaire completed by the participant, consisting of 5 questions, with five possible answers, corresponding to ratings on a scale of 1 to 5. The total score of the scale is proportional to worsening asthma control (1,2). The DPI technique questionnaire involves the scoring of each step involved in the administration of a DPI (3) this is cored by the pharmacist. The Inhaler Technique Questionnaire (InTeQ) is a subjective participant-reported inhaler technique questionnaire. The questionnaire is designed to be a participant tool for reporting and training in inhaler techniques. InTeQ uses 5 questions, with a 5-point Likert scale (4). EuroQol-5D Questionnaire (EQ-5D-5L) is a validated health-related quality of life questionnaire for the assessment of asthma patients (5,6). The EQ-5D-5L is a patient-reported outcome measure that consists of 5 questions with Likert Responses and a visual analog scale. The descriptive system covers 5 aspects of the participant’s health; mobility, self-care, usual activities, pain or discomfort, and anxiety and depression, with 5 possible answers for each question. The visual analog scale is used to capture the participant’s total health on the day of completion.
Participant-reported medication use and adherence will be tracked based a five-point-Likert question. “How often do you not take your medication as prescribed?” adapted from work by Mehuys et al (7).

Pharmacist Training:
Pharmacists participating in the trial will be trained in the study protocol, and execution of AIR therapy adjustments under the standing order, and all associated questionnaires.

Note on Study Intervention:
Doses may be titrated within the pre-defined AIR algorithm steps depending on reported medication use, and control as defined in the standing order. As part of the participants’ diary entries, they will complete the AIR Step questionnaire (AIR algorithm), if indicated that they should change from their current Step, the participant will receive an invitation recommending they seek an asthma review. This can be organized with the PRN investigator or alternatively with their Primary Care Physician, attendance will not be compulsory. All outcomes will be documented within the study database.

Assessment of safety for participants based on the number of adverse events of interest and number of serious adverse events of interest.

Budesonide/formoterol 200µg/6µg (Symbicort® Turbuhaler) is a MedSafe registered and approved medicine. All participants will enter already on this specific medication and will remain under the primary care of their primary care physician. The clinical effects of Symbicort® are well understood and documented as a commonly prescribed medication in New Zealand. Therefore, as part of this study it is intended to only collect safety data relating:

- AE’s directly connected to the participants asthma or use of the medication, Symbicort® Turbuhaler.

- Serious Adverse Events of Special Interest (SAESIs) which include;
o Adverse reactions to the study medication
o Death
o Hospitalisation due to events known to be, or putatively associated with the participants asthma or use of the study medication.

For the purposes of this study, these events will be collected through either the primary care physician, or as self-reported by the participant during diary entries, unscheduled visits or at visit 2, with details will be recorded in the database.

All participants enrolled in the study will be analysed.

Categorical data will be described by counts and proportions; count data by rates and total counts in relation to observation time; ordinal data by cross-tabulation; summaries and continuous data by mean, SD, median, 25th, and 75th percentiles as the inter-quartile range and range.

The primary outcome is the proportion of participants approached through GP database screening, willing to participate in the proposed full trial. A sample size of 25 participants gives a 95% confidence interval for a proportion of 50% of plus or minus 20%. Coupled with the GP mail-out response rate this will provide informative data on the feasibility of recruiting the required numbers for the full trial.

Summary
Brief summary
This single cohort, open-label, non-randomised pilot study aims to assess the feasibility and logistics of undertaking a structured community-pharmacist led asthma review with a capacity to adjust treatment under primary care physician standing order. The primary hypothesis is that a community pharmacist-led asthma review will be acceptable and feasible from patient, pharmacist and primary care physician perspective. This will directly inform the viability of a national multi-center study, powered to detect the effect on asthma control over a 12-month period.

In this pilot study the pharmacist will conduct asthma review of 25 asthmatics, currently prescribed anti-inflammatory reliever (AIR) therapy at step one, as recommended by the NZ Adolescent and Adult Asthma Guidelines. The AIR algorithm was chosen for the simplicity of using a single budesonide/formoterol Turbuhaler during the pilot phase. Enrolled asthmatic participants who are prescribed budesonide/formoterol 200µg/6µg (Symbicort® Turbuhaler) per AIR step 1 (one actuation as required) will attend two study visits at week 0 and week 12 for their asthma reviews, at a local pharmacy in Tauranga, NZ. They will undergo assessment of asthma control, inhaler technique, QoL and titration of AIR therapy under a primary care physician standing order if required.

In between visits participants will complete the asthma control measure, QoL, report asthma medication usage and asthma exacerbations at weeks four and eight. If indicated for reasons of worsening asthma, an unscheduled visit with the community pharmacist will be recommended to the participant where treatment escalation under the standing order will be offered or direct referral for primary care physician review if indicated.

At 12 weeks an asthma review will take place to assess asthma control, inhaler technique, QoL and titration of AIR therapy under a primary care physician standing order if required. Participants, pharmacists and primary care physicians involved in the study will answer study questionnaires to provide feedback on the pilot experience and to evaluate the overall acceptability of pharmacist-led asthma reviews and capacity to adjust treatment of mild asthma.
