The Palliative Performance Scale (PPS) has been widely used for survival prediction among patients with cancer; however, few studies have reviewed PPS scores in heterogeneous palliative care populations across multiple care settings. ⋯ This review provides a broad overview on the prognostic value of the PPS tool for survival among multiple patient populations across care settings. Consistent reporting of PPS scores would facilitate the comparison of survival estimates across end-of-life diagnoses.

The term "palliative approach" has emerged to connote healthcare activities provided consistent with the philosophy of palliative care, but not limited to specialized care providers or settings. A rigorous understanding of the palliative approach requires a conceptual model, which links the philosophy of palliative care to specific actions of practitioners, and is applicable to patients with any life-threatening illness, at any point on the disease trajectory, and provided by any care provider in any setting. This article proposes a conceptual model asserting that a palliative approach exists when care simultaneously addresses whole-person needs, enhances quality of life, and acknowledges mortality. ⋯ The content validity of the proposed conceptual model is supported by the consistent presence of the three domains in published definitions. This conceptual model bridges philosophical definitions and clinician behavior and has potential to inform broad implementation of a palliative approach, at both clinic and system levels.
