Patient safety and computerized medication ordering at Brigham and Women's Hospital

Area of Science:

• Health Informatics
• Patient Safety Research
• Clinical Decision Support Systems

Background:

• Medication safety is a critical challenge in healthcare.
• Computerized physician order entry (CPOE) is a technological solution implemented at Brigham and Women's Hospital (BWH) since 1993 to enhance medication processes.

Purpose of the Study:

• To evaluate the impact of CPOE on medication safety and physician decision-making.
• To assess the effectiveness of CPOE's features in reducing medication errors.

Main Methods:

• Internal development and implementation of a CPOE application at BWH.
• Inclusion of structural features, workflow enhancements, alerts, reminders, and adjunct systems within CPOE.
• Studies assessing CPOE's impact on serious medication errors, adverse drug events, and guideline adherence for specific medications (vancomycin, heparin).

Main Results:

• CPOE has substantially decreased the frequency of serious medication errors.
• The overall medication error rate has seen an even greater reduction due to CPOE implementation.
• Specific studies evaluated the impact of CPOE on vancomycin and heparin usage, and dosing suggestions.

Conclusions:

• CPOE, combined with clinical decision support, significantly enhances patient safety.
• The implementation of CPOE has led to a marked decrease in medication errors.
• Technological interventions like CPOE are vital for improving medication safety in healthcare settings.
