Previous studies have described the high prevalence of malnutrition in hospitalized patients with higher risk of morbidity and mortality, however no gold standard screening tool exist to identify this patients. To identify early pediatric patients at risk for increased adverse clinical outcome, we performed the modified nutritional risk score (mNRS) on 40 infant with different diagnostics consecutively admitted in a public hospital. A total score was obtained and patients were classified in low-and high-risk groups (low-risk: NRS £ 5, high-risk: NRS >5). A modified NRS with same cutoff point was performed to the same patients. Results: patients mean age was 8.72± 6.31 months (50% £ 6 mo), prevalence of malnutrition by W/H (z score) was 22.5% moderate,15% mild, 50% normal, 12.5% overweight. 12.5%had stunting (H/A). Median length of hospital stay was 7.5 days (1-32 ds). Thirty patients had low risk score (LR) and 10 of 40 had high risk score (HR). Media of the number of days in the hospital differed significantly between the LR and HR groups: 6.5 d LR and HR: 14.5 d, p<0.01). The mNRS classified 9 patients in HR (89% of moderate and 17% mild malnourish infants and 89% also had chronic disease) and 31 in LR. Patients with HR also had longer hospital stays (HR:17 DS, LR:6 d, p<0.01). The mNRS had a better that our nutritional screen based on the original NRS on admission pediatric patients at risk for adverse clinical outcome
