A new interdisciplinary research project led by the University Medical Center Mainz and the MSB Medical School Berlin is investigating the effectiveness of an innovative form of care for multimorbid, elderly people with depression: BRIDGE is an activation program that immediately follows a hospital stay in geriatrics or geriatric psychiatry. It is intended to contribute to more physical activity and positive experiences in patients' everyday lives. The aim of the care program is to reduce depressive symptoms and improve patients' quality of life.
