Anesthesia Information Management Systems (AIMS) effectively track neurosurgery operating room utilization. Surgical procedure type, case order, and surgeon experience significantly impact OR efficiency, unlike patient ASA status.
Area of Science:
- Neurosurgery
- Anesthesiology
- Healthcare Management
Background:
- Anesthesia Information Management Systems (AIMS) offer a method for evaluating operating room (OR) utilization.
- Assessing neurosurgery OR utilization patterns using an AIMS was the primary objective of this research.
Purpose of the Study:
- To analyze neurosurgery operating room utilization patterns.
- To identify factors influencing operating room efficiency.
Main Methods:
- A retrospective audit was conducted over one year at a tertiary neurosciences university hospital.
- Timestamps from an AIMS were used to measure various OR activities.
- The study examined the impact of surgical procedure type, ASA physical status, case order, and surgeon experience on OR utilization.
Main Results:
- Data from 1800 patients were analyzed.
- Operating room activity durations varied significantly based on surgery type, ASA grade, case order, and surgeon seniority.
- Surgery and anesthesia durations, along with the time from patient arrival to surgery start, were notably influenced by surgery type, case order, and surgeon seniority (P<0.001), but not ASA score.
Conclusions:
- AIMS provide an effective tool for tracking and understanding OR utilization patterns through activity duration analysis.
- Further multicenter studies are recommended to validate these findings across diverse surgical populations and institutions.
