Does a Clinical Support System for Parenteral Nutrition (PN) Facilitate the Judgement on Choosing the Most Effective Commercial Solution Per Patient (and Modify it, if Necessary)?

Standard formulas of PN have been developed and provided to patients. Only few randomized controlled studies compared standardized vs individualized PN. Individually tailored PN, only if standard PN solutions do not meet patient's nutritional needs. ASPEN society recommends the use computerized prescribing. Technology has enabled the incorporation of medical guidelines in CDSSs. New approach: Comparison of patient's calculated nutritional needs with commercial available solutions.

Inclusion Criteria:Hospitalize Patients unable to be fed via gastrointestinal tract.Hemodynamically stable patients.PN regimen should remain the same for the first 3 days.Exclusion Criteria:Hemodynamically unstable.Anticipated need for parenteral nutrition less than 5 days.
