Abstract Background Depression is the second most common psychiatric illness in old people. Up to 30% of nursing home residents suffer from minor or major depression. Although depressive disorders in old age can be improved and even cured with adequate therapy, they often go unnoticed in nursing home residents and remain untreated. This highlights a striking deficit in health care and might results not only in lower quality of life among those concerned but also in poor physical functioning, premature mortality and increased hospitalization rates. Methods The aim of the interdisciplinary research project DAVOS is to implement an innovative and stepped structural case management program to improve depression treatment in nursing home residents by a modularized intervention and to assess it in terms of its effectiveness. Intervention modules are in line with recommendations given by the German national treatment guidelines for depression (S3 guidelines). Ten nursing homes in Frankfurt, Germany, will participate in the project which aims to recruit a study population of N = 380. The recruitment will continue throughout the trial (open cohort). Persons (>60 years) that live in a nursing home, have no medical diagnosis of dementia and can provide their informed consent to participate are eligible for inclusion in the study. Residents with a clinical diagnosis of dementia, alcohol or substance related disorders or other serious psychiatric illnesses will be excluded. DAVOS is a controlled cluster-randomized study that employs a stepped-wedge design. Discussion Our main hypothesis is that the implementation of the intervention will lead to a decline in the prevalence of depression and a reduction in depression symptoms among the home residents. In addition, we expect the intervention to have a positive impact on secondary outcomes such as level of functioning, quality of life and social participation. The project’s results can make an important contribution towards improving the health care of nursing home residents suffering from late-life depression.
