ContextPrognostication is an essential part of palliative care to aid decision making and negotiate goals of care. The Objective Prognostic Score (OPS) is an easy-to-use prognosticating tool to predict survival among far-advanced cancer patients in palliative care units (PCUs) in Korea.ObjectivesThis study aimed to prospectively validate the OPS for advanced cancer patients in the palliative care teams (PCTs), PCUs, and home-based palliative care (HPC) in Japan.MethodsThis was a substudy of a multicenter prospective cohort study that was conducted to validate and compare prognostic tools among advanced cancer patients in Japan. Participants' survival was calculated according to OPS 3 as a cutoff for predicting survival of less than three weeks. Overall accuracy and area under the receiver operator characteristic curves of OPS 3 were calculated for PCT, PCU, and HPC, respectively.ResultsA total of 1146 cases (PCTs 441, PCUs 519, and HPCs 186 cases) were included in final analyses. The overall accuracy of OPS 3 for predicting three-week survival ranged from 0.70 to 0.78 across diverse palliative care settings. The c-statistics ranged from 0.742 to 0.808 across three settings. Participants in the PCT showed the highest overall accuracy and c-statistics for OPS.ConclusionThe OPS can be used for prognostication among advanced cancer patients in PCT, PCU, and HPC settings.Copyright © 2016 American Academy of Hospice and Palliative Medicine.
