2223 Introduction: Hospital malnutrition presents alarming rates and is characterized as an 24 independent risk factor for mortality. Hospital mortality has been studied as an important 25 indicator of the quality of care. In this sense, the Patient-And Nutrition-Derived Outcome 26 Risk Assessment Score (PANDORA) was created, seeking to associate the nutritional 27 status and in-patients' illness data with the risk of death within 30 days. The study aimed 28 to perform the translation, cross-cultural adaptation to Portuguese and application of an 29 instrument of identification of mortality risk in the hospital setting. Methods: A cross-30 sectional study was carried out in a university hospital in the city of Goiania-GO, Brazil, 31 in 2018. A translation and adaptation of the PANDORA instrument was carried out and 32 it was applied to hospitalized patients to evaluate their power to predict mortality.33 Results: Fifty-four 54 patients were included in the study, most of them female and 33% 34 elderly. More than 16% of the sample presented low weight, which was positively 35 associated with the occurrence of death. The prevalence of cancer was almost 80% and 36 all patients who died had cancer. In the adjusted logistic regression analysis, it was 37 verified that there was no association between the PANDORA score and death in 38 hospitalized patients, however, there was a trend of association of sex and body mass 39 index with death in these patients. Conclusions: In this study, the PANDORA score was 40 not able to predict death in the patients in our sample, but found significant association 41 of low weight at admission with mortality. Further studies are needed for the validation 42 of PANDORA in Portuguese. 43 44 Keywords: Malnutrition, hospital mortality, BMI. 45 3 46 Introduction 47 48 Hospital malnutrition has alarming rates despite therapeutic advances, especially 49 in emerging and industrialized countries. It affects almost 50% of adult patients in Latin 50 American countries, including Brazil. About 40% of in-patients are affected by this 51 condition, which represents an independent risk factor for mortality, besides favoring 52 complications during hospitalization [1,2]. The influence of nutritional status on patient 53 prognosis has been reported in the literature some time ago. Correia and Waitzberg (2003) 54 found a 12.4% mortality rate in malnourished patients, three times higher than those 55 considered well-nourished in the study (4.7%), showing that malnutrition is an 56 independent risk factor for the increase in hospital mortality [3]. 57 According to Tsaousi et al. (2014), inadequate feeding can increase up to eight 58 times the risk of hospital mortality, in addition to prolonged hospital stay [4]. This 59 condition is often neglected and presents a high risk of developing other complications,60 such as surgical and infectious, pressure lesions, increase in length of hospitalization and 61 depletion of the immune system. Its early identification is important to establish the most 62 approp...
