Parenteral nutrition safe practices: Results of the 2003 American Society for Parenteral and Enteral Nutrition Survey

Background: The American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) recently published a revision of its Safe Practices for Parenteral Nutrition guidelines. Because there is a paucity of published scientific evidence to support good practices related to ordering, compounding, and administering parenteral nutrition (PN), a survey was performed in the process of the revision to gain insight into the discrepancies between reported practices and previous guidelines. Methods: A web-based survey consisting of 45 questions was conducted (n = 651) June 1-30, 2003. Respondents were queried about primary practice setting, professional background, processes for writing PN orders, computer order entry of PN orders, problems with P-N orders, and adverse events related to PN. Results: There were 651 survey responses, 90% of which were from hospital-based practitioners. Almost 75% of responders processed between 0 and 20 PN orders per day. Overall, physicians (78%) were responsible for writing PN orders, but dietitians and pharmacists had significant involvement. PN base components were most often ordered as percentage final concentration after admixture (eg, 20% dextrose), which is inconsistent with safe practice guidelines of ordering by total amount per day (eg, 200 g/day). There was no consistent method for ordering PN electrolytes. Approximately 45% of responders reported adverse events directly related to PN that required intervention. Of these events, 25% caused temporary or permanent harm, and 4.8% resulted in a near-death event or death. Conclusions: Although the survey found consistency in PN practices for many areas queried, significant variation exists in the manner by which PN is ordered and labeled.
