The use of social return on investment approaches to evaluate integrated long-term care in high-income countries: A scoping review

Background

The increasing number of older adults with complex care needs underscores the urgent need for improved coordination between health and social services, emphasizing the importance of integrated care models. The Social Return on Investment (SROI) framework is a valuable tool for evaluating the social, economic, and environmental impact of healthcare interventions, including integrated long-term care (LTC) solutions. However, a gap remains in reviews specifically analyzing its application to integrated LTC interventions.

Objective

To examine how SROI has been used to evaluate integrated LTC interventions, particularly for older adults.

Methods

A scoping review of peer-reviewed and grey literature was conducted, covering January 2012 to June 2024, through MEDLINE, CINAHL, Google Scholar, and citation searches. Three independent reviewers assessed study eligibility, following PRISMA guidelines. Data were extracted using PICOS terms and organized into summary tables detailing study characteristics and SROI findings.

Results

Out of 556 screened papers, only 11 studies met the inclusion criteria, with most conducted in the UK. SROI evaluations focused on Personal and Community Resources, such as improved physical and mental health and social connections, while Public Resource benefits, including reduced healthcare workloads, were noted in seven studies. Financial proxies came from sources like HACT Social Value Bank and Global Value Exchange. All studies reported positive SROI ratios, though methodological limitations affect interpretation.

Conclusions

The application of SROI to integrated LTC remains limited, primarily UK-based and reliant on context-specific methodologies. Expanding its use requires standardized methods, broader geographic representation, and localized proxies for more accurate evaluations.
