[Diagnosis of frailty as starting point for training interventions].

The concept of frailty describes an older at-risk population, which has a higher probability for the occurrence of unfavorable health outcomes. It is in the interest of frail individuals as well as the healthcare system to improve the prognosis of these people by targeted interventions. Several systematic reviews and meta-analyses are now available comparing very different interventions in frail older adults. These studies came to the conclusion that training interventions were found to be the most effective. Compared to exercise interventions delivered at participants homes, exercise in groups was found to be more effective. The case finding for such interventions should be carried out with frailty instruments that focus on strength, endurance and/or physical activity. Particularly suitable for this are the frailty criteria of Fried, gait speed or the short physical performance battery (SPPB). From a geriatrics perspective, a comprehensive offer of group training seems to be urgently necessary; however, the implementation requires a large expansion of existing structures and new ways to reach older people with frailty.
