Experts validated the Dynamic Haptic Robotic Trainer (DHRT) for Central Venous Catheterization (CVC) training. They confirmed objective metrics align with perceived patient case difficulty, enhancing training realism and patient safety.

Area of Science:

  • Medical Simulation
  • Robotics in Healthcare
  • Medical Education Technology

Background:

  • Central Venous Catheterization (CVC) has up to 39% adverse effects.
  • Current manikin trainers offer limited anatomical variability and require preceptor assessment.
  • The Dynamic Haptic Robotic Trainer (DHRT) was developed to standardize CVC training and provide automated performance feedback.

Purpose of the Study:

  • To validate the objective assessment metrics within the DHRT system.
  • To investigate the utility of the DHRT in real-world training scenarios.
  • To determine expert consensus on DHRT's assessment capabilities.

Main Methods:

  • Expert interviews were conducted to gather qualitative data.
  • The study focused on the validity of DHRT's automated assessment metrics.

  • Participants evaluated the system's relevance to clinical practice.

    • Main Results:

    • Experts reached consensus on perceptions of patient case difficulty.
    • Characterizations of case difficulty were linked to anatomical features, multiple needle insertions, and prior catheterization experience.
    • The findings support the DHRT's potential for objective performance evaluation.

    Conclusions:

    • The DHRT's objective assessment metrics are considered valid by experts.
    • The DHRT system shows promise in enhancing the standardization and objectivity of CVC training.
    • Further integration into clinical training programs is warranted to improve patient safety and procedural outcomes.
