Figure 3
Decision tree describing the overall hospice referral process. In this figure p = P (D +): probability the patient's LE is less than or equal to 6 months; 1 - p = P (D -): probability the patient's LE is greater than 6 months; Ui, i ∈ [1, 4]: the utilities corresponding to each of the decision model outcomes; Hosp: hospice referral; Rx treatment continuation; Rg: regret associated with an action; HRx : utility losses due to harms of treatment; HHosp: utility losses due to harms of hospice; Hte: utility losses due to harms of the prognostic test (SUPPORT).
