A computerized provider order entry (CPOE) system can provide an efficient means of retrieving and consolidating order lists from multiple electronic clinical practice standards and protocols. However, the consolidated order list may contain exact duplicate or overlapping orders. Benner's framework for levels of nursing expertise can be used to explicate the variability of the nurse's responses to redundancies in order lists and the potential compromise to patient safety. An exploratory case method was performed to consolidate 74 orders from 11 sources. The consolidated order list contained 35% fewer orders after the redundant orders were removed. Our work has shown that many redundant orders may arise by consolidating order lists from multiple electronic standards. It is imperative that consolidated electronic order lists be manageable by the nurse according to their level of clinical and computer expertise, and that redundant orders are resolved before being displayed to the nurse.
