A Scoping Review of Interventions Using an interRAI Information System to Guide Care Management and Assess Intervention Efficacy in Older Adults.

interRAI instruments consist of clinical information systems able to support integrated care. Through a scoping review, we describe how interRAI instruments are used: (1) as interventions (implementation category) and (2) to evaluate interventions (efficacy category) in older adults. In accordance with the PRISMA-ScR framework, we searched 6 databases and conducted dual-independent screening, with conflicts resolved by a third reviewer. Data extraction followed an identical procedure. The review yielded 64 manuscripts, including 43 and 21 categorized as studies of efficacy or implementation, respectively. Findings indicate that interRAI systems are consistently utilized to evaluate or enhance participant-centred outcomes across diverse healthcare settings in 17 countries, with a particular emphasis on home and long-term care. interRAI is a versatile system with the potential to form the foundation of an integrated clinical information system. This review provides a basis for future research testing novel intervention strategies with interRAI systems.
