Web-based Clinical Trials Management Systems (CTMS) present usability challenges. Human-Computer Interaction (HCI) issues, like complex workflows and unclear icons, can hinder system effectiveness in clinical research.

Area of Science:

  • Health Informatics
  • Human-Computer Interaction (HCI)
  • Clinical Research Management

Background:

  • Clinical trials increasingly utilize web-based Clinical Trials Management Systems (CTMS).
  • Human-Computer Interaction (HCI) is critical for the usability and effectiveness of clinical systems.
  • Previous research highlights the impact of HCI on user experience in healthcare IT.

Purpose of the Study:

  • To evaluate the user interface of a web-based CTMS for potential HCI problems.
  • To identify specific usability issues impacting the usefulness of the CTMS.
  • To assess the broader implications of identified design features on other CTMS.

Main Methods:

  • User interface evaluation of a specific web-based Clinical Trials Management System (CTMS).

Related Experiment Videos

  • Analysis focused on identifying human-computer interaction (HCI) problems.
  • Assessment of workflow complexity and icon clarity as key design elements.

    • Main Results:

    • Identified significant human-computer interaction (HCI) problems within the evaluated CTMS.
    • Observed increased workflow complexity attributed to the web application delivery model.
    • Detected potential usability issues stemming from the use of ambiguous icons.

    Conclusions:

    • The evaluated CTMS exhibits HCI issues that may compromise usability and efficiency.
    • Workflow complexity and icon ambiguity are critical design considerations for CTMS.
    • These findings have implications for the design and usability of numerous current CTMS.
