Identification of ‘at risk’ individuals is a core part of primary care practice. Screening programmes are complex and resource-intensive interventions, which must be carefully designed and delivered to maximise benefits and minimise harms. Marginalised groups, (including migrants, sex workers, and homeless individuals) typically participate less in screening programmes due to social, cultural and access barriers, and this can contribute to health inequalities. However, these groups usually have higher burdens of disease and associated impacts for primary care. Various models have been developed to improve uptake of screening and subsequent diagnosis and treatment in marginalised groups in primary care. This workshop aims to critically evaluate these and consider practical implementation strategies.- Understand the principles of screening in primary care and the specific access barriers faced by marginalised groups – Understand the advantages and disadvantages of commonly used interventions to improve participation among underserved groups, such as outreach to community locations, reminder-based interventions and self-test kits – Share and learn from real-world examples of screening models for marginalised groups – Co-design practical, context-specific strategies and solutions to improve screeningMethods Brief presentations, small group exercise, world café. Schedule Introduction (10 mins): Overview of screening for marginalised groups in primary care, including relevant research evidence Group Activity (15 mins): Using participatory facilitation techniques (world café), participants will discuss several models of screening in primary care and their advantages and disadvantages Case Studies (10 mins): Facilitator sharing of case studies and innovations in screening design for marginalised groups including clinical decision support tools for migrants, and co-design of patient support materials Co-Design Activity (20 mins): In small groups, attendees will co-design realistic strategies and models to improve screening Summary (5 mins): Key messages shared back to the group.Attendees will improve understanding of challenges faced by marginalised groups in access and experience of screening in primary care, and models and practical solutions to enhance uptake and linkage to care in marginalised groups.This workshop will enable attendees to explore the barriers and enablers to primary care screening programmes for marginalised groups, and develop context-specific ideas and solutions to apply to their own context.
