Summary
A new statistical strategy can help operating room (OR) managers decide when to move the last surgical case to another room, minimizing overtime labor costs for staff. This method closely matches the efficiency of perfect knowledge, reducing overtime by only a few minutes per case.
Area of Science:
- Health Informatics
- Operations Research
Background:
- Operating room (OR) overtime labor costs are a significant concern for healthcare facilities.
- Efficiently managing OR schedules is crucial for controlling operational expenses and staff workload.
Purpose of the Study:
- To develop and evaluate a statistical strategy for OR information systems to aid managers in deciding whether to move the last surgical case of the day.
- To minimize overtime labor costs for first shift nurses and anesthesia providers.
Main Methods:
- Developed a statistical prediction strategy using historical case duration data from a surgical services information system.
- Estimated incremental overtime labor costs by comparing the proposed strategy to a scenario with perfect knowledge of case durations.
Main Results:
- The statistical strategy, when used to decide case movement, resulted in only 2.0 to 4.3 more minutes of overtime per case compared to perfect retrospective knowledge.
- Alternative information technologies (e.g., real-time tracking, cameras, displays) offered comparable, minimal overtime reductions of 2-4 minutes per movable case.
Conclusions:
- A programmed OR information system using historical data can effectively assist in reducing overtime labor costs.
- The proposed strategy offers a practical approach to optimize OR scheduling and reduce costs, with benefits comparable to more advanced technologies.
