Error reduction when prescribing neonatal parenteral nutrition

A neonatal intensive care unit audit of 204 parenteral nutrition (PN) orders revealed a 27.9% PN prescribing error rate, with errors by pediatric residents exceeding those by neonatal nurse practitioners (NNPs) (39% versus 16%; P < 0.001). Our objective was to reduce the PN prescribing error rate by implementing an ordering improvement process. An interactive computerized PN worksheet, used voluntarily, was introduced and its impact analyzed in a retrospective cross-sectional study. A time management study was performed. Analysis of 480 PN orders revealed that the PN prescribing error rate was 11.7%, with no difference in error rates between pediatric residents and NNPs (12.3% versus 10.5%). Use of the interactive computerized PN worksheet was associated with a reduction in the prescribing error rate from 14.5 to 6.8% for all PN orders ( P = 0.016) and from 29.3 to 9.6% for peripheral PN orders ( P = 0.002). All 12 errors that occurred in the 177 PN prescriptions completed using the computerized PN worksheet were due to avoidable data entry or transcription mistakes. The time management study led to system improvements in PN ordering. We recommend that an interactive computerized PN worksheet be used to prescribe peripheral PN and thus reduce errors.
