Claims-based predicted deficit-accumulation frailty index

1. Claims-based predicted deficit-accumulation frailty index is associated with Medicare home health use in humans (+1.10 percentage points per +0.01 DAFI; 95% CI 1.05–1.15).

1. Claims-based predicted deficit-accumulation frailty index predicts observed OASIS Start-of-Care deficit-accumulation frailty index in humans (AUC 0.715; calibration slope 1.111).

   “The claims-based DAFI was closely calibrated to observed OASIS DAFI (area under the curve = 0.715; slope = 1.111).”
