The Palliative Prognostic Index (PPI) is a prognostication tool for palliative care @entity1 based on clinical indices developed in Japan and further validated by one study in the UK. The aim of this study was to test its prediction accuracy in a large inpatient hospice sample. The admitting doctor in three inpatient hospices calculated the PPI score on admission. Two hundred and sixty-two @entity1 were included in this study. Based on the PPI score, three subgroups were identified. Group 1 corresponded to @entity1 with PPI  <=4 and the median survival of 53   days (95% CI 40 to 80   days). Group 2 corresponded to those with PPI >4 and  <=6 and the median survival 15   days (95% CI 12 to 26   days) and Group 3 corresponded to @entity1 with PPI >6 and the median survival of 5   days (95% CI 3 to 7   days). In this study, PPI was able to identify @entity1 ' likelihood of dying within 3   weeks with a sensitivity of 64% and specificity of 83%. It was able to identify a 6-week survival chance with a sensitivity of 62% and specificity of 86%. A one-unit increase in PPI score was estimated to increase the hazard for @entity204 by a factor of 1.33 (95% CI 1.26 to 1.40), based on fitting a stratified Cox proportional hazards model. The authors conclude that PPI can be used to predict prognosis for @entity1 with @entity5 .
