This study introduces Dynamic Time Warping (DTW) for analyzing Surgical Process Models (SPMs) to automatically classify surgeon expertise. The method effectively distinguishes between senior and junior surgeons based on surgical process data.

Area of Science:

  • Computer-assisted surgery
  • Surgical process modeling
  • Medical data analysis

Background:

  • Surgical Process Models (SPMs) are emerging tools for analyzing surgical interventions.
  • A key challenge is developing metrics to compare and evaluate Surgical Processes (SPs).
  • Correlating metrics with pre-operative data aids in classifying surgeries and surgeon expertise.

Purpose of the Study:

  • To explore the automatic classification of Surgical Processes (SPs) using the Dynamic Time Warping (DTW) algorithm.
  • To assess the effectiveness of DTW in discriminating surgeon expertise levels.
  • To evaluate the potential for creating new metrics for surgical comparison and assessment.

Main Methods:

  • Utilized the Dynamic Time Warping (DTW) algorithm to compute similarity measures between SPMs.

  • Focused on activity types and sequencing within SPs, minimizing time differences.
  • Conducted supervised and unsupervised classification experiments on 24 lumbar disk herniation surgeries.

    • Main Results:

    • The DTW-based approach successfully discriminated between senior and junior surgeons.
    • Automatic classification of surgeons based on their level of expertise was achieved.
    • DTW proved complementary to traditional methods focusing solely on time and activity counts.

    Conclusions:

    • The DTW algorithm offers a viable method for the automatic classification of surgical processes and surgeon expertise.
    • This approach opens new avenues for developing objective metrics in surgical assessment.
    • Findings support the use of DTW in computer-assisted intervention systems for performance evaluation.
