Computerized physician order entry (POE) offers numerous advantages over traditional paper-based systems. Through rapid information retrieval and efficient data management, POE systems have the potential to improve the quality of patient care. Four specific areas in which benefits are seen with POE are process improvements, resource utilization, clinical decision support, and guide implementation.1

First, POE improves the process of order writing by generating legible orders that require less clarification from nurses and pharmacists.2 The process of ordering medications is streamd by eliminating needless transcription steps.3 4 Furthermore, the convenience of being able to access a patient's chart and order medications from any computer terminal reduces the time spent searching for charts.2

Second, POE, when it displays laboratory and cost information, changes provider prescribing habits so that drug choice is more cost effective.5 Physician order entry results in the use of more formulary drugs, which lowers costs.6 Many studies have shown reductions in hospital and patient costs after the implementation of an order entry system that alerted physicians to drug and test prices, warned of potential test redundancy, and gave antibiotic recommendations.7 8 9 10 11.12

Perhaps the most exciting advantage of POE over written orders is the ability to provide clinical decision support at the time of ordering. Decision support can include the display of patient laboratory data, allergy information, and drug–drug interactions.13 This information retrieval addresses a frequent system failure identified by Leape et al.14—the lack of appropriate knowledge at the time of medication ordering. Through these support features, POE has been shown to improve patient outcomes by reducing medication errors and adverse drug events.15 16 17 18 19

The fourth advantage of POE systems is the ability to incorporate clinical guides into the system.20 …
