SHIFT delivered a co-created & piloted model for future service provision to improve sexual health amongst the target groups, including techniques for engaging with hard-to-reach groups. A model was designed for people aged over 45 using a confidential web-based process to self-assess/be advised on next steps, but co-creation ensured those less at ease with technology were fully engaged with the model. Using partner expertise, and by identifying organisations who work directly with socio-economically disadvantaged groups, the model was adapted to reach these groups. Mobile units accessed homeless people and others who do not/cannot access local public health services. Services are multilingual and culturally/subject sensitive to reach groups such as migrants and sex workers. SHIFT also delivered a jointly produced & piloted training programme relevant to all parts of the 2Seas area, based on extensive engagement with healthcare professionals, implemented via existing services.
