Effects of the Resident Assessment Instrument in home care settings

Deficits in quality, a lack of professional process management and, most importantly, neglect of outcome quality are criticized in long-term care. A cluster randomized, controlled trial was conducted to assess whether the Resident Assessment Instrument (RAI) can help to improve or stabilize functional abilities (ADL, IADL) and cognitive skills (MMST), improve quality of life (EQ-5D), and reduce institutionalization, thereby, increasing outcome quality. A total of 69 home care services throughout Germany were included and randomized. The treatment group (n=36) received training in RAI and was supported by the research team during the study (13 months). Comparison of mean differences between the treatment and control groups (n=33) showed no significant effect. Although the multilevel regression results show that clients in the treatment group fared better in terms of ADLs and IADLs (smaller decline) and were less likely to move to nursing homes and be hospitalized, none of these effects is significant. The lack of significance might result from the small number of clients included in the study. Moreover, RAI was not fully implemented and even partial implementation required more time than expected.
