Healthcare Professionals' Perspectives on the Impact of a Multicomponent Intervention for Older People With Frailty Discharged From Hospital–A Theory‐Based Evaluation

According to the involved healthcare professionals, the complex training, social, and nutritional intervention seemed to work well for older people with frailty, although the nutritional intervention was received differently. The important mechanisms were the social element and the personal approach of the physiotherapists, which perceivably prompted training efforts and results and yielded good mental outcomes. The organisation of a similar multicomponent intervention should consider integrating the nutritional intervention and frame the use of goal setting and testing further. The findings provided novel insights to working mechanisms in multicomponent interventions for older people with frailty, especially regarding the social component, which may inform future interventions.
