Until the present moment, the project conducted a scoping review to gain a comprehensive understanding of the structure of PC-I-LTC ecosystems. We identified the relevant characteristics of PC-I-LTC ecosystems using a micro-based perspective and addressed the use of Social Return on Investment (SROI) to evaluate integrated LTC solutions for older adults. A further literature review was done to identify validated evaluation criteria and possible indicators for the three transversal topics: person-centredness, inequalities and technical requirements. In addition to the base scientific work, the BUILD project has generated evidence on how territorial, gendered, and socio-economic inequalities shape care transitions and care trajectories across different European welfare states. This knowledge was further enriched through qualitative research. Semi-structured interviews have been conducted with more than 120 participants, including older adults with complex care needs, informal caregivers, and formal care professionals. The combination of these methods has yielded in-depth insights into the lived experiences of care transitions, the mechanisms through which social inequalities influence these processes, and the specific needs and wishes of older adults and their caregivers in relation to integrated long-term care. In a further work package researchers are developing the methodology for engagement activities, Online Deliberative Forums and the Scenario workshops. The engagement methodology will facilitate the identification of barriers in current care practices and highlight opportunities for improvement. The outcome of the latter-mentioned work will contribute to the development of a toolbox that supports the implementation of PC-I-LTC in Europe. A dedicated project group has conducted a critical review of existing regulatory frameworks for integrated care solutions in Europe. A framework for person-centred integrated long-term care (PC-I-LTC) has been developed, drawing on established models such as SCIROCCO and SELFIE, as well as insights from experts and members of the Association Board. In parallel, the group is working on a comparative analysis of current policy practices and an evidence-based gap analysis.
