The project aims at deriving frailty (FI) and complexity (CI) indices from data collected with the Resident Instrument Assessment - Home Care adapted for Switzerland (RAI-HC). Data were collected in 2015 by trained nurses in clinical routine with the primary purposes of health state assessment and individual home care planning. The study consists in a retrospective secondary analysis of health data from the Minimal Data Set (MDS), used to derive frailty and complexity indices according to published definitions and guidelines for index derivation. The analysis further aims at estimating the predictive power of these indices on undesirable health outcomes (falls, hospitalizations and deaths). The goal is to provide home care institutions and nurses valid algorithms to compute useful clinical indicators without additional assessment that the one routinely done with the RAI-HC.

Inclusion Criteria:

• Men and women aged 18 or older who were assessed in 2015 with the Swiss RAI-HC in clinical routine for care planning by the Geneva Institution for Home care and Assistance (imad) in Geneva, Switzerland

Exclusion Criteria:

• Men and women aged 17 or younger and/or who did not receive a full RAI-HC assessment in 2015

Adult applicants for home care services provided by imad (Geneva, Switzerland) who received a first RAI-HC assessment in 2015 for routine care planning purposes

The coded datasets supporting the findings of this study are not publicly available for they belong to imad and are not the property of the authors of the study. The data analyzed for the study could be made available from the authors upon reasonable request and with prior agreement by imad.
