Summary
Computerized provider order entry (CPOE) patient identity verification occurred more often than not. However, verification rates differed significantly between CPOE systems, impacting patient safety.
Area of Science:
- Health Informatics
- Patient Safety
- Clinical Workflow Analysis
Background:
- Computerized provider order entry (CPOE) systems are widely used in healthcare.
- Effective patient identity verification within CPOE is crucial for patient safety.
- Understanding verification practices in different CPOE systems is essential for optimizing workflows.
Purpose of the Study:
- To determine the rates of patient identity verification during CPOE.
- To identify when and where in the ordering process verification occurs.
- To compare verification practices across different CPOE systems.
Main Methods:
- Fifty-five physicians from four healthcare systems participated.
- Simulated patient scenarios were used with Epic and Cerner CPOE systems.
- Physician eye movements were recorded and analyzed to track verification behavior.
Main Results:
- Patient identity was verified in 62.4% of instances, significantly more than not.
- Vendor A CPOE showed significantly higher verification rates than Vendor B.
- Verification occurred more frequently before order signing with Vendor A (88.4%) compared to Vendor B.
Conclusions:
- CPOE system design significantly influences patient identity verification rates.
- Variations in verification practices have potential patient safety implications.
- Further research into CPOE design and training is needed to improve verification consistency.

Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...

Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.

The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...
