A person-centred primary care pharmacist-led osteoporosis review for optimising medicines (PHORM): a protocol for the development and co-design of a model consultation intervention

Introduction: Adherence to medicines in osteoporosis is poor, with estimated 1 year persistence rates between 16% and 60%. Poor adherence is complex, relating to combinations of fear of side effects, beliefs about medication being unnecessary, doubts about effectiveness and the burden of medication management. This is compounded by an absence of monitoring, as many patients are effectively discharged from ongoing care following the initial prescription. Clinical pharmacists in general practice are a relatively new workforce in the UK NHS; this is an unexplored professional group that could provide person-centred, adherence-focused interventions in an osteoporosis context. A model consultation intervention to be delivered by clinical pharmacists in general practice for patients already prescribed fracture prevention medications will be developed using existing evidence and theory and empirical qualitative work outlined in this protocol.

Methods and analysis: We will investigate the current practice and barriers and facilitators to a clinical pharmacist-led osteoporosis intervention, including exploring training needs, through focus groups with people living with osteoporosis, pharmacists, general practitioners, osteoporosis specialists and service designers/commissioners. Framework analysis will identify and prioritise salient themes, followed by mapping codes to the theoretical domains framework and normalisation process theory to understand integration and implementation issues. We will further develop the content and model of care for the new consultation intervention through co-design workshops with stakeholder and patient and public involvement and engagement group members. The intervention in practice will be refined in a sequential process with workshops and in-practice testing with people prescribed fracture prevention medication, pharmacists and the multidisciplinary team.

Ethics and dissemination: Ethical approval was obtained from NHS North West—Greater Manchester South Research Ethics Committee (Ref 23/NW/0199). Dissemination and knowledge mobilisation will be facilitated through a range of national bodies/stakeholders. Impact and implementation plans will accelerate this research towards a future clinical trial to determine cost and clinical effectiveness.
