A hospital admission often represents a turning point, not only for the care recipient but also for their informal caregiver. Informal caregivers take on various roles: they can act as a bridge between the home environment and the hospital, provide reassurance and continuity for the care recipient during their stay, and more. At the same time, hospitalization is often accompanied by stress and uncertainty for both the care recipient and the caregiver. An increasing number of hospitals are developing policies around caregiver participation and support. This is driven by a growing focus on person-centered care, patient and family satisfaction, and the shortage of healthcare staff. For professionals, involving caregivers is not always straightforward and may lead to role conflicts and new challenges. In this paper, we present the results of a qualitative exploratory study in a regional hospital in Flanders (Belgian) that recently developed and implemented a policy on caregiver participation. How do the three parties in the triad (care recipients – informal caregivers – professionals) experience caregiver participation and support in the hospital context? Through semi-structured interviews with 11 informal caregivers, 9 care recipients, and 13 professional healthcare providers, we mapped perspectives, points of attention, and success factors for triadic working. Based on these results and an exploration of good practices in other Flemish hospitals, we formulate a number of concrete good practices and recommendations for triadic working in the hospital context. The study shows that actively shaping the relationship between care recipient, caregiver, and professional healthcare providers can contribute to a higher perceived quality of care and benefits for all parties.
