Reducing the inappropriate use of parenteral nutrition in an acute care teaching hospital

Background: Parenteral nutrition IPN) is a form of nutrition that can be life-saving, but its use has inherent risks and it is expensive. Nutrition support teams have been shown to reduce both the rate of complications and excessive use of PN. Methods: Criteria were established to evaluate the appropriateness of PN use in a 487-bed community teaching hospital. A prospective study of 50 consecutive patients, who received either central or peripheral PN, was conducted. Results: The 50 patients received 469 days of PN. We found that 233 (49.7%) of the 469 days of PN were avoidable. This resulted in the creation of a formal approval process that required prior approval by a physician-directed multidisciplinary advisory committee before PN could be instituted. The amount of PN subsequently decreased from 500 patient days of PN per month to less than 100. Conclusions: This study supports the idea that inappropriate use of PN can be reduced by physician education plus the continuing oversight of a physician-directed multidisciplinary advisory group.
