Long-term care (LTC) workers and informal carers are the backbone of LTC for millions of people with health/care needs across Europe. However, their demanding roles risk negatively impacting their mental health and well-being. Moreover, despite shared responsibilities, the integration and collaboration between these groups is rare, and a missed opportunity to foster mutual support and more person-centred care. The EU Horizon Europe-funded WELL CARE project (2024–2027) addresses these needs by identifying, evaluating, and promoting good practices that support carers’ mental well-being and foster care partnerships. Researchers and advocacy organisations from Germany, Italy, the Netherlands, Slovenia, and Sweden conducted a comprehensive review of scientific and grey literature published between 2013 and March 2024, following PRISMA guidelines. Searches across eight multidisciplinary scientific databases yielded 16,357 potential good practices; after rigorous screening and quality assessment, 134 remained. Grey literature, and consortium partners’ input added 103 more, and interviews with 23 experts contributed 14 additional practices. In total, after removing overlaps and applying selection criteria, 170 good practices were identified. After a systematic ranking process, 40 top-ranked practices were selected. Key findings from the analysis of the top 40 good practices highlighted that the majority focused on informal carers, while fewer addressed LTC workers, although 34 practices had the potential to foster care partnerships. Care recipients were predominantly older adults, followed by working-age adults, often living with cognitive decline or mental health conditions. Most practices occurred in ordinary home settings, followed by digital environments, and the majority of the collected practices included training initiatives or organisational/management approaches. Examples of good practices, representing different typologies and countries, will be showcased during the presentation. Delegates will gain insights into good practices that enhance mental well-being, resilience, and care partnerships among LTC workers and informal carers, paving the way for more integrated, person-centred care across Europe.
