Computerized Physician Order Entry Paper

Computerized Physician Order Entry (CPOE) systems allow clinicians to enter medication and other orders into a central electronic system. Those orders can then be conveyed to a pharmacy or other departments.1 Published studies report that CPOE reduces medication errors.2 However, there is a growing awareness and increasing documentation of concerns that CPOE can also introduce or facilitate new errors.3 Koppel et al's recent report on computerized physician order entry (CPOE) evaluated its role in facilitating medication errors. According to Sociologist Ross Koppel, PhD, of the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania School of Medicine study, turned out that CPOE system can promotes and leads technology
Examples of these errors are when a physician selects an inappropriate product, or the risk of ordering conflicting or duplicative medication because the CPOE system separates the process of ordering from the process of discontinuing existing medications.3 According to Koppel medication discontinuation failures (medication-canceling ambiguities) is aggravated by the computer interface or overlap and multiple-screen displays of medications. It is easy to select the wrong patient file because names and drugs are very close to each other. Since a patient’s medication information is seldom synthesized on 1 screen, many screens might be needed to see all of a patient’s medications, increasing the likelihood of selecting a wrong medication. Moreover different CPOE computer screens might offer differing colors and typefaces for the same information, enhancing misinterpretation as physicians switch among screens and can easily be confused.3 Procedure-Linked Medication Discontinuation Faults and Conflicting or Duplication Medications are the other outcomes results from fragmentation
