Terminology use in electronic health records: basic principles

Area of Science:

• Health Informatics
• Clinical Documentation

Background:

• Electronic health records (EHRs) are vital for cost-effective, safe, and high-quality patient care.
• Standardized clinical classification systems and terminologies are fundamental components of EHR systems.

Purpose of the Study:

• To outline the primary applications of clinical information within EHRs.
• To explain the rationale for maintaining consistency in clinical practice documentation.
• To differentiate between classification systems and reference terminologies in healthcare settings.

Main Methods:

• Literature review on EHR functionalities and standardization.
• Analysis of clinical information use cases.
• Comparative analysis of classification systems and reference terminologies.

Main Results:

• EHRs enhance patient safety, quality of care, and evidence-based practice.
• Clear understanding of requirements is essential for selecting appropriate EHR terminologies.
• Distinction made between classification systems (grouping) and reference terminologies (standardized terms).

Conclusions:

• Standardized terminologies are indispensable for robust EHR systems.
• Informed selection of classification systems and terminologies optimizes EHR utility.
• Understanding the differences between these systems is key for effective clinical informatics.
