Summary
Efficiency metrics differ significantly between operating room (OR) anesthesia and non-operating room anesthesia (NORA) cases. NORA cases show shorter turnover times but longer start delays, highlighting the need for distinct NORA benchmarks.
Area of Science:
- Anesthesiology
- Healthcare Management
- Quality Improvement
Background:
- Operating room (OR) efficiency metrics are well-studied, but non-operating room anesthesia (NORA) efficiency lacks comparable research.
- Existing OR standards may not be applicable to NORA settings due to inherent differences.
Purpose of the Study:
- To investigate and compare key efficiency metrics between OR and NORA anesthesia cases.
- To determine if commonly used efficiency metrics show significant variations across different anesthesia settings.
Main Methods:
- Retrospective analysis of calendar year 2015 data from a single tertiary care hospital.
- Measured and compared turnover times (TOTs), cancellation rates, first case start delays, and scheduling errors for OR and NORA cases.
Main Results:
- NORA cases had 50% shorter average turnover times (16.21 min vs. 37.18 min) but greater variation.
- NORA cases had a 64% lower cancellation rate but experienced first case start delays twice as long as OR cases (24.45 min vs. 10.58 min).
- NORA case times were more frequently overestimated, with less variation compared to OR cases.
Conclusions:
- Significant differences exist in efficiency metrics between OR and NORA anesthesia settings.
- Current OR-based efficiency benchmarks are likely inappropriate for NORA environments.
- Further research is needed to establish validated efficiency benchmarks specifically for NORA procedures.
