Computerized physician order entry and medication errors in a pediatric critical care unit

Area of Science:

• Pediatric Critical Care Medicine
• Health Informatics
• Patient Safety

Background:

• Medication errors are a significant concern in pediatric healthcare.
• Computerized physician order entry (CPOE) systems have demonstrated effectiveness in reducing medication errors and adverse drug events (ADEs) in adult populations.
• The impact of CPOE on medication ordering errors in pediatric critical care units (PCCUs) remains under-reported.

Purpose of the Study:

• To evaluate the impact of implementing a CPOE system on the frequency of medication ordering errors within a pediatric critical care unit.
• To assess the reduction in medication prescribing errors (MPEs), rule violations (RVs), and potential adverse drug events (ADEs) after CPOE implementation.

Main Methods:

• A prospective trial was conducted in a 20-bed PCCU at a tertiary-care children's hospital.
• Medication orders for 514 pediatric patients were reviewed before and after CPOE implementation.
• Errors were classified as potential ADEs, MPEs, and RVs.

Main Results:

• A total of 13,828 medication orders were analyzed.
• Before CPOE, rates were 2.2 potential ADEs, 30.1 MPEs, and 6.8 RVs per 100 orders.
• After CPOE, rates decreased to 1.3 potential ADEs, 0.2 MPEs, and 0.1 RVs per 100 orders, representing an overall error reduction of 95.9%.

Conclusions:

• CPOE implementation led to a substantial decrease in medication errors in the PCCU.
• The system achieved near-complete elimination of MPEs and RVs.
• While significant, the reduction in potential ADEs was less pronounced compared to prescribing errors and rule violations.
