Surgeon Skill and Perioperative Outcomes in Robot-Assisted Partial Nephrectomy

Area of Science:

• Urology
• Surgical Technology
• Medical Quality Improvement

Background:

• Surgeon technical skill in complex procedures impacts patient outcomes.
• Assessing surgeon proficiency is crucial for improving surgical care.
• Robot-assisted surgery offers new avenues for evaluating technical skill.

Purpose of the Study:

• To evaluate the association between surgeon technical skill scores in robot-assisted partial nephrectomy and patient outcomes.
• To determine if video-based skill assessment can identify factors related to surgical success.

Main Methods:

• 10 urological surgeons submitted videos of robot-assisted partial nephrectomies.
• Videos were segmented and rated by 24 blinded peer surgeons using a validated skill scale.
• Clinical outcomes (length of stay, blood loss, ischemia time, margins, readmissions) were assessed via registry.

Main Results:

• Higher technical skill scores correlated with significantly lower rates of prolonged length of stay, excessive blood loss, positive surgical margins, emergency department visits, and readmissions.
• Increased surgeon skill was also associated with higher partial nephrectomy volume.
• The mean overall performance score was 4.1 (SD, 0.4).

Conclusions:

• Higher technical skill in robot-assisted partial nephrectomy is associated with improved patient outcomes.
• Video-based surgical skill assessment is a valuable tool for quality improvement initiatives.
• These findings support the use of video review to enhance patient care in robotic surgery.
