Area of Science:

  • Medical Education
  • Computational Biology
  • Emergency Medicine

Background:

  • Trauma injuries are a leading global cause of death, underscoring the importance of effective trauma management training.
  • Current training methods often lack objective analysis of adherence to established protocols and guidelines.
  • The Advanced Trauma Life Support (ATLS) manual provides a foundation for standardized trauma care.

Purpose of the Study:

  • To design and develop an automated system for evaluating trauma management protocol compliance.
  • To enhance the objectivity and detail of trauma intervention assessment compared to existing methods.
  • To create a web-based tool for accessible trauma simulation and evaluation.

Main Methods:

  • A modified Needleman-Wunsch (NW) algorithm was developed to incorporate key aspects of trauma management.
  • The algorithm evaluates the sequence and type of actions taken during trauma interventions against established protocols.
  • A web-based trauma simulator was utilized for experimental testing with medical students and residents.

Main Results:

  • The modified NW algorithm achieved a low error rate (below 0.07) across various simulated trauma scenarios.
  • Validation by trauma experts confirmed the algorithm's accuracy, with a median difference of 0 compared to expert assessments.
  • The study identified the optimal combination of scores for the modified NW algorithm variables.

Conclusions:

  • The modified NW algorithm offers a successful and objective method for measuring adherence to trauma management protocols.
  • This automated evaluation system has the potential to significantly improve the quality and consistency of trauma care training.
  • The system's objective scoring provides valuable feedback for refining medical professionals' skills in trauma management.
