Background
Malnutrition is common in hospitalized patients and strategies to improve energy and protein intake have a positive impact on outcome. Despite early evidence suggesting the usefulness of peripheral parenteral nutrition (PPN), its adoption has been hampered by concerns regarding safety and efficacy. This study addresses this issue.
Methods
This prospective observational study was performed in medical and surgical inpatients in who were screened for nutrition risk and assessed using Subjective Global Assessment (SGA). Data captured included nutrition status, energy and protein requirements, intravenous access, indications for PPN, use of supplemental micronutrients, and disposition of patients on PPN.
Results
Ninety‐eight patients were recruited from two centers over 8 months. The average age was 61.5 years, the mean Charlson Comorbidity Index was 4.21 (±3.09), 52% were male, and 48% were admitted to medicine, whereas 52% were admitted to surgery. Thirty‐three percent of patients were SGA C, 44% were SGA B, and 19% were SGA A. Twenty‐seven percent of patients had cancer. The average length of hospital stay was 22 days. The main indications for PPN were gastrointestinal tract dysfunction (72%) and postsurgical status (16%). PPN provided an average of 1296 kcal (±191) and 46 g of protein (±7). Intravenous access complications in patients receiving PPN did not occur in excess of expected. Almost 40% of patients required transition to central PN.
Conclusions
PPN is a safe, effective way to deliver supplemental protein, energy, and micronutrients to malnourished patients and supports transition to other modes of nutrition care.
