Of the 107 pa+ents evaluated (34 female, mean age 68y), 55.1% reached the protein target in the first 4 days (x̅ =4.56±2.07). Normal weight was the most frequent BMI (34.6%); pa+ents BMI mean was 27.88±5.88. Pa+ents severity scores are shown in Table 1. Delayed (>4 days) protein target reach (p=0.038) and underweight (p=0.009) were related with mortality occurrence in the ICU-Table 2. It was observed a posi+ve correla+on (n=67; rs=0.331; p=0.006) between the +me that protein target was reached and the length of stay in the ICU (figure 1).
