Table 4 Logistic regression analysis assessing models associated with the receipt of nursing visits in palliative home care clients

From: The interRAI CHESS scale is comparable to the palliative performance scale in predicting 90-day mortality in a palliative home care population

MODEL 1: PPS

(reference = 10)a

MODEL 2: PPS collapsed (reference = 70–100)

MODEL 3: PPS collapsed (reference = 70–100)

MODEL 4: interRAI CHESS (reference = 0)

MODEL 5: CHESS & additional interRAI PC items

  1. a Note that different reference groups are used for models 1–4 due to sample size limitations in the highest PPS scores.
  2. *p < 0.05; **p < 0.001; All other variables had a p < 0.0001, except for all levels of age, which was not significant.
