Utilising an Accelerated Delphi Process to Develop Guidance and Protocols for Telepresence Applications in Remote Robotic Surgery Training.

European urology open science·2021

A modified Delphi method established generalizable error measures for surgical simulators like the ES3. This provides a framework for comparable data in surgical education and training.

Area of Science:

  • Medical Education
  • Surgical Simulation
  • Human Factors Engineering

Background:

  • Virtual reality surgical simulators are increasingly used for training.
  • Standardized methods for error measurement in simulators are lacking.
  • This hinders comparability and validation of training outcomes.

Purpose of the Study:

  • To develop a generalizable methodology for identifying and measuring errors in surgical simulators.
  • To create a framework for establishing evidence-based data in surgical training.
  • To facilitate comparable, interoperable, and sharable data among researchers.

Main Methods:

  • Utilized the modified Delphi method, a proven consensus-building technique.
  • Derived a first-order approximation of measurable errors for the ES3 virtual reality surgical simulator.

  • Ensured the methodology and derived errors were designed for broad generalizability across surgical disciplines.

    • Main Results:

    • Successfully generated a set of generalizable error measures for virtual reality surgical simulation.
    • Demonstrated the applicability of the methodology beyond sinus surgery to other otolaryngologic and general surgical procedures.
    • Established a foundation for creating uniform error measurement frameworks.

    Conclusions:

    • The modified Delphi method provides a rigorous, scientific basis for error measurement in surgical simulation.
    • This approach enables the generation of comparable, evidence-based data for training validation and outcomes analysis.
    • The framework supports interoperability and data sharing among surgical education researchers.
