The MDS-CHESS scale: a new measure to predict mortality in institutionalized older people
Abstract
OBJECTIVES: To develop a scale predicting mortality and other adverse outcomes associated with frailty. DESIGN: Observational study based on Minimum Data Set (MDS) 2.0 and mortality data. SETTING: Ontario chronic hospitals. PARTICIPANTS: All chronic hospital patients (N = 28,495) assessed with the MDS 2.0 after mandatory implementation in July 1996 followed until May 1999. MEASUREMENTS: MDS 2.0 assessments done as part of normal practice mainly by registered nurses or multidisciplinary teams in a chronic hospital. Mortality data are available from the accompanying discharge tracking form. RESULTS: The MDS‐Changes in Health, End‐stage disease and Symptoms and Signs (CHESS) score is a composite measure addressing changes in health, end‐stage disease, and symptoms and signs of medical problems. It is a strong predictor of mortality ( P < . 0001) independent of the effects of age, sex, activities of daily living impairment, cognition, and do‐not‐resuscitate orders. It is also strongly associated with physician activity, complex medical procedures, and pain ( P < . 001 for each dependent variable). CONCLUSIONS: The CHESS score provides a useful new MDS‐based test to predict mortality and to measure instability in health as a clinical outcome.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
