Background Adequate coverage of the nutritional needs during hospitalisation is of the utmost importance for patients’ recovery.
Purpose To evaluate the quality of parenteral nutritional support in our hospital to find points for improvement.
Material and methods Prospective observational study of all patients with parenteral nutrition (PN) over a period of two months. PN prescription was considered justified, if was in agreement with the ESPEN 2009 criteria. PN length was appropriate if it was for less than 7 days for peripheral PN (PPN) or for more than 7 days for central PN (CPN).
Protein and energy needs were calculated by weight and adjusting for metabolic stress factor (Low, Moderate and High: 1, 1.2 and 1.4 g protein/kg/day respectively for proteins and 150, 130 and 110 nonprotein Kcal/gN respectively for energy).
Nutritional needs were calculated only in patients with CPN and recorded weight. PN was considered adequate if it covered 85–115% of the calculated needs.
Spss 20.0 was used for statistical calculation.
Results 49 patients were included. The average age was 65 ± 14 years and average body mass index was 26 ± 5 Kg/m2. 40 patients (81.6%) had CPN and 9 (18.4%) PPN. PN prescription was justified in 46 patients (93.6%). PN length was optimal in 30 patients (75%) with CPN and 3 (33%) with PPN (p = 0.043).
Nutritional needs were calculated in 37 patients. Caloric and protein intakes were suitable in 22 (59.5%) and 15 (40.5%) patients respectively. 6 patients (16.2%) had caloric overfeeding and 20 (54.1%) had protein overfeeding. 9 patients (24.3%) had insufficient calories and 2 (5.4%) insufficient protein. 10 patients (20.4%) met all objectives and therefore had appropriate PN.
Conclusion PN prescription is generally justified but PPN length is often inappropriate.
In the light of these results, the appropriate coverage of nutritional needs and PPN prescription for seven or fewer days, are the most important points to improve.
