Summary:Insufficient screening and management of malnutrition leads to increase morbidity and mortality. Aims: to evaluate the characteristics and clinical outcomes of malnourished patients referred to a specialized outpatient clinic for the management of malnutrition (primary); to compare the latter according to malnutrition severity; to determine the factors associated with severe malnutrition and mortality; to compare the consistency of the decided medical nutrition therapy with the European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines (secondary). This retrospective, observational study included malnourished adults referred for the first time to the specialized nutrition consultation of a teaching University Hospital during 50 months. Malnutrition was diagnosed according to the Global Leadership Initiative on Malnutrition criteria, including body composition assessment by bioimpedance analysis. Statistics: Chi2 or Fisher, Student or Wilcoxon rank-sum tests; multivariable logistic regression to assess the factors associated with severe malnutrition and mortality. 108 malnourished adults were included: 74% had severe malnutrition. The main secondary diagnosis was digestive cancer (48.2%). During the follow-up (median = 70 days) after the first nutritional consultation, 11% of patients were admitted at hospital, 19% had infections and 23.1% died, without any difference according to malnutrition severity. Severely malnourished patients had lower body mass index, a smaller fat mass index (FMI) (4.6 ± 1.8 vs 6.0 ± 2.5 kg/m2; p = 0.01), and a higher level of total body water (64.7 ± 7.1 vs 60.6 ± 5.4%; p = 0.02), compared to moderately malnourished individuals. A low FMI (odds ratio = 0.72 [0.54–0.96]) was the only factor significantly associated with severe malnutrition. We did not find any factor associated with mortality. There was a moderate consistency (47.1%) between the decided medical nutrition therapy and the ESPEN guidelines of nutritional care. Conclusions: Adults referred for the first time to a specialized nutritional consultation present mostly with severe malnutrition and are at risk for significant complications, leading to a high mortality rate. In this population, a low FMI is associated with severe malnutrition. An earlier diagnosis and care of malnutrition and an earlier referral to clinical nutrition units would improve outcomes. •A low body fat mass index was the only factor significantly associated with severe malnutrition.•During the follow-up, 11% of patients were admitted at hospital after the first nutritional consultation, 19% had infections and 23.1% died.•There was a moderate consistency between the decided medical nutrition therapy and the ESPEN guidelines of nutritional care.
