Background: Current literature suggests clinicians are not accurate in prognostication when estimating survival times of palliative care patients. There are reported studies in which the Palliative Performance Scale (PPS) is used as a prognostic tool to predict survival of these patients. Yet, their findings are different in terms of the presence of distinct PPS survival profiles and significant covariates.

Objective: This study investigates the use of PPS as a prognostication tool for estimating survival times of patients with life-limiting illness in a palliative care unit. These findings are compared to those from earlier studies in terms of PPS survival profiles and covariates. Methods: This is a retrospective cohort study in which the admission PPS scores of 733 palliative care patients admitted between March 3, 2000 and August 9, 2002 were examined for survival patterns. Other predictors for survival included …
