Rationale: Hospital malnutrition is a prevalent condition associated with significant adverse clinical outcomes, underscoring the critical need for early patient identification. Consequently, guidelines recommend nutritional risk screening or assessment within 72 hours of admission to facilitate timely and appropriate intervention.

Methods: Patients admitted to an Internal Medicine ward identified as being at nutritional risk (NRS-2002 score > 3) were prospectively enrolled. Following a comprehensive malnutrition assessment, participants were categorized based on whether or not they received a formal nutrition consultation during hospitalization. Within relevant groups, adherence to prescribed Oral Nutritional Supplements (ONS) was evaluated, further stratifying patients based on achieving at least 75% versus less than 75% intake of the recommended dosage.

Results: A total of 205 patients (45.9% female, mean age 67.0 ± 14.1 years, 100% admitted for emergency reasons) were enrolled at Fondazione Policlinico A. Gemelli IRCCS in Rome. Only 54 patients (26.3%) were assessed by the Clinical Nutrition Unit within 72 hours of admission. The percentage of patients prescribed oral nutritional supplements (ONS) was higher among those who underwent a specialized evaluation (59% vs. 31%; p<0.0001). Patients receiving ONS had a longer length of stay (10.9 vs. 5.3 days; p=0.001) but experienced lower in-hospital mortality (3.2% vs. 11.1%; p=0.03).

Conclusion: Early nutritional assessment and the subsequent implementation of targeted clinical nutrition interventions, including ensuring adequate ONS intake, are crucial for improving outcomes in hospitalized patients identified as being at nutritional risk.
