User Satisfaction Evaluation of the EHR4CR Query Builder: A Multisite Patient Count Cohort System.

Area of Science:

• Health Informatics
• Clinical Research Technology

Background:

• The Electronic Health Records for Clinical Research (EHR4CR) project aims to facilitate the reuse of Electronic Health Records (EHRs) to improve clinical research efficiency.
• User acceptance is critical for the adoption of health informatics platforms like EHR4CR.

Purpose of the Study:

• To evaluate user satisfaction with the EHR4CR multisite patient count cohort system.
• To assess the usability and user experience of the EHR4CR platform in a pilot program.

Main Methods:

• A user satisfaction evaluation was conducted with testers (n=38) from 5 countries.
• Testers performed three main tasks after 30 minutes of self-training, with task completion time around 20 minutes per task.
• The System Usability Scale (SUS) and an additional satisfaction questionnaire were used to collect data.

Main Results:

• The System Usability Scale score was 55.83 (SD: 15.37), indicating moderate user satisfaction.
• Positive feedback was received regarding the interface design and query creation procedures.
• The most complex task was rated as difficult, highlighting areas for system improvement.

Conclusions:

• The EHR4CR platform demonstrates moderate user satisfaction, with positive aspects in interface design and basic query functions.
• Further system enhancements are required to address difficulties encountered with complex queries.
• Improving the handling of complex queries is essential for maximizing the efficiency of clinical research processes using EHR data.
