A mixed methods protocol for an impact and implementation evaluation of the Pharmacy First Services for management of common conditions in England.

OBJECTIVES: In response to high levels of demand for primary medical services in England, characterized by longer appointment waiting times and delayed referrals, the Government developed its National Health Service (NHS) Primary Care Recovery Plan. A key component of the plan is Pharmacy First (PF), which involves participating community pharmacies supplying prescription-only medicine after consultation with a pharmacist for seven common conditions: earache, uncomplicated urinary tract infections in women, sore throat, sinusitis, impetigo, shingles, and infected insect bites. The study aims to evaluate the implementation of the PF service and its impact on the volume of prescribing, case mix of General Practitioner consultations, accident and emergency department and other hospital use, equity of access, and cost for different groups of patients in different contexts, as well as its acceptability and fidelity. METHODS: A 36-month, mixed methods evaluation with five elements, namely evidence synthesis, semi-structured interviews, focus groups, quantitative analysis of impacts before and after implementation (e.g. using interrupted time series analysis) using routine data, and an economic evaluation. Findings will be synthesized and interpreted using the Consolidated Framework for Implementation Research supplemented by Proctor's Implementation Outcomes Framework. CONCLUSIONS: The evaluation should have service level, policy, professional, and research impact both in England and beyond. This includes generating evidence to show: whether PF contributes to improving primary healthcare access, assessing the quality of antimicrobial use, identifying the scope for refinements to PF, and, overall, informing better implementation of PF. The findings will also provide robust evidence to enable policymakers to determine how to enhance the role of community pharmacy in England in the future. Furthermore, the evaluation will develop a data dashboard, and the methods and codes used to interrogate it (though not the patient data), will be made publicly available that could support other similar evaluations in England and internationally.
