TY - JOUR T1 - How Community Pharmacy Outreach Engages Underserved Populations in Preventive Care: A Realist Review of Trust, Service Accessibility, Interprofessional Partnerships, and Sustained Participation A1 - Aisha Rahman A1 - Kwame Boateng A1 - Naledi Mokoena JF - Annals of Pharmacy Education, Safety, and Public Health Advocacy JO - Ann Pharm Educ Saf Public Health Advocacy SN - 3108-4850 Y1 - 2026 VL - 6 IS - 2 DO - 10.51847/QMcgLMUBl6 SP - 225 EP - 236 N2 - Community pharmacies offer opportunities to deliver preventive care to populations experiencing geographical, financial, cultural, linguistic and organizational barriers to healthcare. However, service availability, initial attendance and sustained participation represent different outcomes. Understanding how outreach influences these outcomes requires attention to the circumstances in which services operate and the reasoning of people who encounter them. To examine how, why, for whom and under which circumstances community pharmacy outreach supports engagement and sustained participation in preventive care, with particular attention to relational trust, service accessibility and interprofessional partnerships. A realist review approach was developed around initial programme theory, iterative evidence identification, relevance and rigour appraisal, and context–mechanism–outcome analysis. Public literature discovery and preliminary evidence mapping identified candidate publications addressing pharmacy access, preventive services, underserved populations and interprofessional collaboration. The available search record did not establish a complete, deduplicated and eligibility-screened evidence set. Preliminary evidence mapping identified explanatory questions concerning whether outreach resources are perceived as credible, practically usable and connected to subsequent care. The proposed analytical distinctions concern initial contact, preventive-service uptake, completed referral, follow-up and sustained participation. Formal evidence-supported context–mechanism–outcome configurations and final included-evidence counts remain unestablished. A realist explanation of pharmacy outreach must account for how service resources interact with social circumstances, professional relationships and organizational arrangements. Its claims concerning sustained participation require longitudinal evidence and a completed, transparent synthesis.
