Understanding Persistent Pain: A Feasibility Study for the Use of a Digital Decision Aid Tool for Persistent Pain in a Pharmacy Setting

The study design is a randomised feasibility study. Patient participants will take part in a pain consultation with a pharmacist to discuss pain management in a shared decision making (SDM) process. The unit of randomisation will be the patient participant. Thus, pharmacists will randomise patients to one of two groups: an intervention group who will receive a digital DAT for self-completion as part of the consultation and a control group which not use the digital DAT.

How the study will be implemented will be dependent on research restrictions due to the COVID-19 pandemic. If restrictions on research are in place, all study activities will be done remotely. If research restrictions are lifted the investigators will offer both remote and in person activities, depending on the participants preference.

Registered pharmacists in National Health Service (NHS) Grampian (see Section 5.1.) will be invited to take part in the study. As part of the assessment of feasibility for a future randomised control trial (RCT), a mixture of community and General Practitioner (GP)-surgery based pharmacists will be recruited. Recruited pharmacists will identify and invite patients living with persistent pain to a pain consultation. Pharmacists and patients will discuss current lifestyle and pain history, after which the pharmacist will recommend pain management plans that follow a person centred care (PCC) approach. Patients in the intervention group will receive the digital DAT - named UPP (Understanding Persistent Pain) - for self-completion with the help of the pharmacist. The DAT will generate a personalised report on the patient's preferences that can be used to discuss different PCC management plans. Management plans will be based on strategies routinely available in clinical practice4.

Heterogeneity in pharmacist-led pain consultations means that consultations are likely to differ across pharmacists. This study will allow the researchers to characterise different types of pharmacist-led pain consultations for a future larger study. As such, having a standardised control consultation falls beyond the scope of this feasibility study. Similarly, heterogeneity in current practice will cause agreed plans to differ across pharmacists and patients. These will also depend on the prescribing qualifications of the pharmacist.

The patient's GP will be informed of the person's participation and, in some cases, the recommendations/findings of the consultation. Where a prescription only medicine is deemed beneficial, pharmacists who are qualified independent prescribers will recommend this directly. Pharmacists without this qualification will, with the agreement of the patient, suggest to patients that they should book an appointment with the GP and send a referral letter to the GP with the recommendation for the prescription only medicine. Follow up consultations with the pharmacist will be arranged according to each pharmacist's current practice.
