Background: Enteral nutrition (EN) is an effective nutritional intervention for patients at risk of malnutrition or malnourished. However, complications such as gastrointestinal intolerance, hyperglycemia or refeeding syndrome can be triggered by EN.
Aim: To investigate the effects of a tube feeding formula (TFF) on patients' nutritional status, biochemical status, bowel habits and safety.
Methodology: Observational, prospective and multicenter study. Patients ≥ 18 years, undernourished or at nutritional risk, who were prescribed a high-calorie, high-protein, fiber-fortified TFF were included. Patients were evaluated over a period of eight weeks (baseline [V1], four weeks [V2] and eight weeks [V3]).
Results: A statistically significant increase in weight (1.5 kg), body mass index (0.6 kg/m2) and nutritional intake (59.7 kcal/day) was observed between V1 and V2. Between V1 and V3, there was a statistically significant decrease in the percentage of individuals with abnormal biochemical markers for glucose, potassium, total protein and albumin. The number of patients' bowel movements remained stable throughout the study with a mean of 1.1 daily bowel movements.
Conclusion: The TFF was safe and well tolerated, improving patients' nutritional status without altering patients' bowel habits.
