Effects of the resident assessment instrument on the care process and health outcomes in nursing homes: a review of the literature.

The objective of the paper is to review the effects of the implementation of the Resident Assessemnt Instrument (RAI) on process measures (quality of care plans and staff satisfaction) and outcome measures (health problems and quality of life) in nursing homes. All available publications on the effects of the RAI were included in the review. The most positive effects of the RAI were found in improvements in the comprehensiveness and accuracy of the care plans. As regards outcome quality, the RAI method had most positive effects on the health condition of nursing home residents with diminished physical and mental functioning. In psychosocial areas of assessment, fewer positive effects were found. We concluded that positive effects have been found, based on pre-test-post-test non-controlled designs. Control-groups designs are needed in future evaluation studies to determine if these positive results will hold. (aut.ref.)
