Enhancement of clinician workflow with computer order entry

Area of Science:

• Health Informatics
• Clinical Systems Engineering
• Medical Informatics

Background:

• Physician-operated order entry systems offer significant institutional benefits.
• These systems can improve order consistency, accuracy, safety, and cost-effectiveness.
• Effective implementation requires addressing diverse ordering scenarios and patient needs.

Purpose of the Study:

• To highlight the importance of considering various clinical workflows in designing computerized order entry systems.
• To present specific requirements for different ordering scenarios, including transfers, post-operative, pre-admission, and discharge orders.
• To demonstrate how a well-designed system can support and enhance clinical workflow.

Main Methods:

• Analysis of different order writing and communication scenarios within a healthcare institution.
• Identification of unique requirements for specific patient populations (e.g., intensive care, chemotherapy) and order types (e.g., warfarin).
• Development and evaluation of a computerized order entry system designed to accommodate these diverse needs and workflows.

Main Results:

• Computerized order entry systems can significantly improve the quality and efficiency of medical orders.
• Tailoring system design to specific clinical contexts (e.g., limited order sets, critical care) is crucial for success.
• The presented system approach aims to enhance, not disrupt, existing clinical workflows.

Conclusions:

• Computerized order entry systems are vital for improving healthcare delivery.
• System design must be flexible and responsive to the complexities of clinical practice.
• Optimizing order entry systems enhances patient safety and institutional efficiency.
