A Randomized Controlled Trial Evaluating the Effectiveness of Displaying Patient Photographs in an Electronic Health Record to Prevent Wrong-Patient Electronic Orders

Although Computerized provider order entry (CPOE) systems are associated with a reduction in medical errors, when orders are placed electronically certain types of errors, including placing orders on the wrong patient, may occur more frequently. The danger of wrong-patient electronic orders was highlighted by one hospital's report of over 5,000 wrong patient orders in 1 year. With the growing use of electronic health records (EHRs), an effective method to minimize wrong-patient orders is needed. One study showed that patient photographs displayed in EHR systems decreased wrong-patient orders from 12 to 3 per year after patient photographs were implemented. While encouraging, this study was limited due to its small sample size, compared outcomes of the intervention participants to outcomes of a comparison group similar in demographics but may have differed in ways that were not measured in the study (quasi-experimental design), and reliance on voluntary reporting of errors by providers, which is known to be unreliable and greatly underestimate the actual error rate. This research proposes to use an automated and reliable measure of wrong-patient errors instead of voluntary reporting will demonstrate that patient photographs can significantly prevent wrong-patient orders.
