BackgroundCurrent models of patient‐enacted involvement do not capture the nuanced dynamic and interactional nature of involvement in care. This is important for the development of flexible interventions that can support patients to ‘reach‐in’ to complex health‐care systems.ObjectiveTo develop a dynamic and interactional model of patient‐enacted involvement in care.Search strategyElectronic search strategy run in five databases and adapted to run in an Internet search engine supplemented with searching of reference lists and forward citations.Inclusion criteriaQualitative empirical published reports of older people's experiences of care transitions from hospital to home.Data extraction and synthesisReported findings meeting our definition of involvement in care initially coded into an existing framework. Progression from deductive to inductive coding leads to the development of a new framework and thereafter a model representing changing states of involvement.Main resultsPatients and caregivers occupy and move through multiple states of involvement in response to perceived interactions with health‐care professionals as they attempt to resolve health‐ and well‐being‐related goals. ‘Non‐involvement’, ‘information‐acting’, ‘challenging and chasing’ and ‘autonomous‐acting’ were the main states of involvement. Feeling uninvolved as a consequence of perceived exclusion leads patients to act autonomously, creating the potential to cause harm.Discussion and conclusionThe model suggests that involvement is highly challenging for older people during care transitions. Going forward, interventions which seek to support patient involvement should attempt to address the dynamic states of involvement and their mediating factors.
