Orthopedic Surgery
Health Informatics
Machine Learning in Healthcare

Background:

Operating room (OR) efficiency is crucial for surgical success and patient outcomes.
Identifying key performance indicators (KPIs) that influence OR efficiency is essential for improvement.
Traditional methods may not fully capture the complex interplay of factors affecting OR performance.

Purpose of the Study:

To leverage machine learning (ML) to identify critical metrics impacting surgical success and team performance in the OR.
To develop a predictive model incorporating team, patient, and surgery-specific factors to enhance OR efficiency.
To establish data-driven benchmarks for optimizing operating room workflows.

Main Methods:

Utilized a retrospective dataset of 4796 joint replacement cases (2012-2020) involving surgeons, nurses, and anesthesiologists.
Employed data mining and ML algorithms to identify patterns and relationships influencing surgical success, defined as completing four joints within an eight-hour shift in one OR.
Developed decision tree models for performance benchmarks and success probability prediction.

Main Results:

The ML model accurately predicted OR success with 72% accuracy (AUC=0.72).
Key predictors of success included anesthesia preparation time, surgical preparation time, procedure time, anesthesia finish time, and joint replacement type.
Established performance benchmarks for critical times (e.g., anesthesia preparation, surgical preparation, procedure duration) to achieve a 77-89% success rate.

Conclusions:

AI-ML models can predict operating room success without requiring additional resources.
Established benchmarks serve to track OR performance, evaluate strategic changes, inform decision-making, and identify opportunities for teamwork enhancement.
This approach offers a data-driven strategy for optimizing surgical efficiency and outcomes.
