This study aimed to evaluate the prognostic performance of the combined PPI-LPS score and compare it with that of PPI, LPS, and the Palliative Prognostic Score (PaP).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The PPI-LPS score was calculated as the arithmetic mean of scaled PPI and LPS values: Round[((PPI\/1.5) + LPS)\/2]. A total of 1061 terminally ill patients with cancer admitted to an acute care hospital with a palliative care unit were included. Prognostic performance was compared among PPI, LPS, PaP, and PPI-LPS in terms of (1) discrimination of 30-, 60-, and 90-day mortality; (2) accuracy of median survival prediction; and (3) categorical survival classification as \u201cdays\u201d (0-13 days), \u201cweeks\u201d (14-55 days), or \u201cmonths\u201d (&gt;55 days).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The PPI-LPS score demonstrated the highest discriminative ability for 30-, 60-, and 90-day mortality (accuracy: 74%, 80%, and 80%, respectively).
