Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Frailty Index

    Index with a value ranging from 0 to 100, computed as the sum of health deficits recorded with the RAI-HC MDS divided by the number of deficits considered

    1 year

  • Complexity Index

    Index with a value ranging from 0 to 100, computed as the sum of complexity items recorded with the RAI-HC MDS divided by the number of items considered

    1 year

Secondary Outcomes (3)

  • Falls

    6 months on average

  • Hospitalizations

    6 months on average

  • Mortality

    through study completion, an average of 5 year
