" Calculating the daily changing composition of parenteral nutrition for small newborn infants is troublesome and time consuming routine work in neonatal intensive care. The task needs expertise and experience and is prone to inherent calculation errors. In 1996 we introduced a knowledge-based system called VIE-PNN at the neonatal intensive care unit (NICU). It supports the daily calculation of nutrition plans for combined parenteral and enteral nutrition of newborn infants utilizing textbook knowledge and clinical rules of expert neonatologists. VIE-PNN uses a HTML-based client-server architecture and is integrated into the intranet of the local patient data management system (PDMS). The system is now in daily routine use for more than 5 years at 2 NICUs. Its main benefits are considerable time savings for clinicians and an increased quality of care. The main factors for success are its ease of use, its robustness, the integration into the PDMS, and the maintainability by the clinical experts. Most important, physicians highly value the time savings the system provides. "

" Calculating the daily changing composition of parenteral nutrition for small newborn infants is troublesome and time consuming routine work in neonatal intensive care. The task needs expertise and experience and is prone to inherent calculation errors. We designed VIE-PNN (Vienna Expert System for Parenteral Nutrition of Neonates), a knowledge-based system (KBS) in order to reduce daily routine work and calculation errors. VIE-PNN was redesigned several times because the clinicians accepted the system only when it saved time. The most recent version of VIE-PNN uses an Hypertext Markup Language (HTML)-based client-server architecture and is integrated into the intranet of the local patient data management system. Since more than 3 years all parenteral nutrition plans are calculated using VIE-PNN. Evaluating the system's performance and the users contentedness, we compared 50 nutrition plans calculated in parallel using VIE-PNN or a hand-held calculator, retrospectively analyzed more than 5000 nutrition plans stored in VIE-PNNs database and evaluated a user questionnaire. Nutrition plans were calculated in a mean time of 2.4 versus 7.1min using VIE-PNN or the hand-held calculator. Errors and omissions in the nutrition plans were detected in 22% versus 56% and errors in the VIE-PNN's plans occurring only with interactively changed values. Reviews of stored plans show that a mean of 4 out of 16 parameters were interactively changed. VIE-PNN was well accepted. Most important reasons for the successful operation of VIE-PNN in the daily routine work were time savings and robustness of the system. "
