Computerized Physician Order Entry Systems and Medication Errors

JAMA. 2005;294(2):178-181. doi:10.1001/jama.294.2.178-a

To the Editor: We are concerned about a number of aspects of the study on computerized physician order entry (CPOE) systems and medication errors by Dr Koppel and colleagues.1 First, the system used was TDS, which dates to the mid 1990s. As an old clinical information system, it indeed exhibits many of the flaws pointed out in the article. However, the vendor’s newer product was designed to address the specific problems outlined in the article. The University of Pennsylvania implemented the newer product and its latest version of the CPOE system more than a year ago.
