A Strategy to Overcome Under-Reporting Issues of Voluntary Medication Error Reporting System, Part II: Changes in Number of Reports by a Counter-error Measure—Computerized Prescriber Order Entry

This simple article is an addendum to our previous study to handle underreporting issues in medical error reporting systems. If you are interested in the qualitative aspect of the reported errors, you may want to refer to it. If your interest resides more in the comparing of the numbers of error reports for various situations, while controlling for the under-reporting problem, this article offers you some hints. We used computerized prescriber order entry (CPOE) as an example, comparing the difference in prescribing error reports between hospitals with and without CPOE. After controlling all potential covariates, including hospital-level clustering, we found hospitals with CPOE experienced 2.48 times more prescribing error reports than hospitals without CPOE. The result itself is meaningful, but we suggest you focus more on the methodology, which is our contribution to the patient safety society to overcome underreporting issues with voluntary error reporting system data.
