Background: This systematic review has previously been published in Geriatric Nursing [1], (http://creativecommons.org/licenses/by/4.0/ ). As the global population ages, the demand for healthcare services for older people outside of hospital has grown significantly. This study is contemporary in the time of an ongoing reform to an integrated and person-centred care in Sweden. It provides a holistic overview of the current state of person-centered care interventions for older people in out-of-hospital settings. The review encompasses various healthcare settings, including primary care, home care, long-term care, and community-based services. Objective: The aim of this systematic review was to explore the content and essential components of implemented person-centered care in the out-of-hospital context for people aged 65 and older. Method: A systematic review was conducted, searching for published research in several electronic databases between 2017 and 2019. Original studies with both qualitative and quantitative methods were included and assessed according to the quality assessment tools EPHPP and CASP. Results: The results underscored four interconnected themes crucial to the implementation of person-centered care: 1. Recognizing and validating the patient as a whole person. 2. Co-creating a tailored health plan. 3. Engaging in teamwork across various healthcare professionals and fostering cooperation with both the older persons and their relatives. 4. Establishing a person-centered base with focus on preventive and health-promoting actions. Conclusion: Practicing a person-centred ethic, approaching an interpersonal and inter-professional teamwork is a crucial prerequisite to co-create integrated and person-centred care practice with and for older people and their relatives in their unique context. The importance of preventive and health-promoting actions is emphasized in teamwork and consultation. It underscores the need for continued research, policy development, and practice innovation, to promote the adoption of person-centered care as a standard approach to caring for older adults in diverse healthcare settings.
