Abstract NHS England's Elective Care Transformation Programme supports local health and care systems to work together to transform local elective care services to better manage rising demand for elective care services; improve patient experience and access to care and provide more integrated, person-centred care. This aims to ensure patients see the right person, in the right place, first time.The Elective Care Development Collaborative was established to support rapid change led by frontline teams in three strategic themes - rethinking referrals, shared decision-making and self-management support, and transforming outpatients. In Wave 2 of the Elective Care Development Collaborative, local health and care systems in Dorset, Stockport, Norfolk and Lincolnshire formed teams to develop, test and spread innovation in delivering elective care services in a 100 day Challenge.Once the teams were aligned with the strategic aim of the programme, the challenge consisted of capturing the learning to allow sharing with other localities. The methodology used to capture the learning were 5-stage logic models - consisting of inputs, activities, outputs, outcomes, and impacts. These logic models, alongside case studies demonstrating the narrative of the journey the teams had been through, provided the information for a series of handbooks to be developed, aimed at other localities, with opportunities for improvement for their elective services.The handbooks are now available at: https://www.england.nhs.uk/elective-care-transformation/handbooks-and-case-studies/ External funding details Funded by NHS England as an NHS England initiative.
