[Resident assessment instrument. Application options and relevance for Germany]

The Resident Assessment Instrument (RAI) is a structured and standardized instrument to improve the quality of long-term care. It is based on the Minimum Data Set (MDS) 3.0 to generate clinical data for nursing planning. Further practical applications are calculation of the costs of nursing care (using a classification of residents), measurement and transparency of nursing home quality (using quality indicators) and epidemiological surveys (using uniform data from assessments). The RAI is used nationwide in the USA, to some extent in other countries and in Germany predominantly in the context of research. The paper briefly describes the historical development of the different RAI variations (particularly with respect to the MDS), presents the central utilization options and ends with a critical discussion of possibilities and limits of the RAI.
