Effects of enteral nutrition on patients with pressure lesions: a single-center, pilot study.

OBJECTIVE: Protein-energetic malnutrition (PEM) affects prognosis and mortality in elderly patients as an inadequate nutritional status is a risk factor for the development and worsening of pressure sores (PS). We aimed to evaluate the incidence of PEM in outpatients with PS and to study the impact of nutritional support on the stage of PS. PATIENTS AND METHODS: PS patients, divided in a group treated with artificial nutrition (group A) and those fed orally (group B) at home, were consecutively enrolled in the Integrated Home Care program of Ascoli Piceno between June and September 2015. At T0 the patients underwent medical history, nutritional, anthropometric/biochemical parameters assessment, and the staging of the PS. The same assessments and staging of the pressure lesions were performed three months later (T1). RESULTS: Group A (n=25) started from a better nutritional status vs. group B (n=25) at T0, according to MNA assessment. Group A showed a significant improvement in nutritional status correlating with detailed control of nutrients intake and improvement of PS stage (T0 vs. T1, p<0.05). On the other hand, group B showed a significant difference between nutrients intake and nutritional needs that correlated with both malnutrition state increase and worsening of the PS staging (T0 vs. T1, p<0.05). CONCLUSIONS: The present study shows that PEM has a significant prevalence in the elder, in general, and in older people with PS, in particular. A targeted nutritional intake can prevent and help the healing of PS.
