Defining a theoretical framework for a quality referral at the primary-secondary care interface: a systematic scoping review with qualitative content analysis.

Abstract (English)

BACKGROUND: Referral from primary to secondary care is a crucial component of a GP's role, yet the quality of referrals varies widely. Inadequate referral information can delay patient care, compromise outcomes, and strain healthcare resources. There is currently no universally accepted framework for what constitutes a quality referral. AIM: To define a theoretical framework for high-quality referrals between primary and secondary care, and to identify key components of effective referral practice. DESIGN AND SETTING: A systematic scoping review using a systematic search of Embase, CINAHL, and Medline databases was conducted to identify research published between July 1999 and August 2024. A qualitative content analysis describing the quality of GP referrals was conducted following Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Review guidelines. METHOD: Eligible studies included English-language publications with referral quality as a primary outcome, covering referrals from primary to secondary care. Studies were analysed inductively using qualitative content analysis to identify key attributes of effective referrals, which were grouped into overarching themes. RESULTS: The search yielded 3461 studies; 54 were included in analysis. Four themes were identified: patient clinical characteristics (complete medical history, relevant investigations, and physical examination); clinical reasoning (clear referral indication, structured template use, guideline adherence, and appropriate urgency classification); patient factors (patient understanding, patient preference, and flow of information); and referral barriers (time constraints, limited specialty expertise, and educational needs). A quality-improvement checklist based on these findings was developed. CONCLUSION: Referral letters must balance detail and usability, taking a pragmatic approach to ensure clinical reasoning, relevant history, and patient involvement are communicated clearly, while avoiding unnecessary administrative burden.
