[Development, application and evaluation of nursing interventions for people with dementia in nursing homes in Germany--a literature review].

In 2007 guidelines for the care of people with dementia living in nursing homes, especially for handling challenging behaviour, have been published that recommend certain interventions. The aim of this study is a systematic review of publications about projects and the development and utilisation of interventions recommended in the German guideline in German nursing homes. For this purpose, 22 publications from 8 projects were analysed. The analysis was carried out on the basis of the CReDECI-criteria for the reporting of complex interventions. The publications described the application of reminiscence-therapy, Snoezelen, Dementia Care Mapping (DCM) and the use of understanding diagnostics as well as assessment instruments. Although the interventions were based on similar theoretical frames and had the same aim they contained different components. For the implementation a considerably amount of teaching and support by the project members was needed. A process evaluation as well as information about necessary adaptations to general conditions was given seldom. Partly, information that is important for the use in practice as well as in continuative studies is missing in the publications.
