INTRODUCTION: Prognostication is fundamental in clinical practice, particularly for the palliative care doctors. It facilitates health care decisions and end of life planning,namely timely referral to palliative care. Its’ imprecise nature and the associated practical difficulties are well documented in the literature. Despite the many instruments available to overcome those difficulties, they are not routinely used in clinical practice and none of them was ever validated for the Portuguese population.MATERIAL AND METHODS: The PPI is one of those models. It was developed in Japan for patients with terminal cancer in palliative care and later validated in other countries and for other palliative settings. It is a simple score system that combines PPS with oral intake and the existence or absence of edema, dyspnea at rest and delirium,dividing the patients in 3 groups with different survival times (< 3 weeks, 3 to 6 week sand > 6 weeks).In our dissertation we expose the linguistic validation of the original instrument to the Portuguese language in Portugal, setting the ground for its posterior transcultural and psychometric validation.RESULTS: To achieve that, we translated the original instrument into the Portuguese language in Portugal, obtaining conceptual and semantic equivalence, thus obtaining aversion of the instrument ready to be used for the rest of the validation process. CONCLUSION: With a later study, that we pretend to perform in the near future, we intend to provide the Portuguese health care professionals with a simple, easy to apply prognostic tool with a good predictive value, easily reproductible, that allows, among other aspects, the individualization of care, the identification of homogeneous groups of patients and the standardizations of concepts in healthcare
