Context and Meaning in EHR Displays

Area of Science:

• Health Informatics
• Human-Computer Interaction
• Medical Error Research

Background:

• Electronic Health Records (EHRs) are critical tools in modern healthcare.
• The usability of EHR data displays is often suboptimal, failing to account for clinical context.
• Contextual factors significantly impact EHR usability and patient safety.

Purpose of the Study:

• To highlight the insensitivity of many EHR data displays to context and user needs.
• To examine how contextual variations in EHR displays affect medication prescribing.
• To illustrate how display differences across EHR systems can lead to errors.

Main Methods:

• Analysis of EHR screenshots demonstrating variations in medication and allergy displays.
• Qualitative assessment of display inconsistencies across different EHR systems and implementations.
• Identification of display features that contribute to confusion and cognitive burden.

Main Results:

• Significant contextual variations exist in EHR medication and allergy displays.
• These variations are often inconsistent and lack clear logic, contributing to confusion.
• Display differences can lead to clinician misunderstandings and misinterpretations of critical patient data.

Conclusions:

• Contextual awareness in EHR design is crucial for improving usability and patient safety.
• Standardization and context-sensitive design principles are needed for EHR medication and allergy displays.
• Addressing display variations can reduce cognitive burden and mitigate medical errors in prescribing.
