PurposeIntegrated health and social care initiatives are increasing and health and social care systems are aiming to improve health and social outcomes in disadvantaged groups. There is a global dialogue surrounding improving services by shifting to an integrated health and social care approach. There is consensus of what is “health care”; however, the “social care” definition remains less explored. The authors describe the state of “social care” within the current integrated care literature and identify the depth of integration in current health and social care initiatives.Design/methodology/approachA narrative literature review, searching Medline, PsychINFO, CINAHL, PubMed, Scopus and Cochrane databases and grey literature (from 2016 to 2021), employing a search strategy, was conducted.FindingsIn total. 276 studies were eligible for full-text review, and 33 studies were included and categorised in types: “social care as community outreach dialogues”, “social care as addressing an ageing population”, “social care as targeting multimorbidity and corresponding social risks factors” and “social care as initiatives addressing the fragmentation of services”. Most initiatives were implemented in the United Kingdom. In total, 21 studies reported expanding integrated governance and partnerships; 27 studies reported having health and social care staff with clear integrated governance; 17 had dedicated funding and 11 used data-sharing and the integration of systems’ records.Originality/valueThe authors' demonstrate that social care approaches are expanding beyond the elderly, and these models have been used to respond to multimorbidity [including coronavirus disease 2019 (COVID-19)], targeting priority groups and individuals with complex presentations.
