OR Turnover Time Reduction: Lessons from Ambulatory Centers

Operating room (OR) inefficiencies are one of the most significant cost and throughput challenges faced by hospitals today. Among the most impactful of these inefficiencies is OR turnover time—the critical window between the end of one surgery and the beginning of the next.
In many hospitals, this process is plagued with delays, unclear responsibilities, and poor communication. Meanwhile, ambulatory surgery centers (ASCs) are leading the way in OR turnover time reduction, routinely achieving turnover times of 10–15 minutes compared to the 30–60 minutes often seen in hospitals.
Why such a stark difference? And more importantly, what lessons from ambulatory centers can hospitals adopt to improve their own surgical performance?
This post explores these questions through the lens of OR turnover time reduction, offering real-world examples, proven strategies, and actionable takeaways.
Why OR Turnover Time Matters More Than Ever
In today’s healthcare environment, every minute in the OR matters. The operating room is one of the most resource-intensive areas in any hospital, representing up to 40% of a facility’s revenue. Yet inefficient turnover times often lead to:
Delayed case starts
Surgeon dissatisfaction
Increased overtime costs
Patient dissatisfaction and anxiety
Decreased overall surgical volume
In a value-based care model where efficiency, safety, and patient satisfaction drive success, OR turnover time reduction is not a luxury—it’s a necessity.
What Are Ambulatory Surgery Centers Doing Right?
Ambulatory surgery centers (ASCs) were built from the ground up to deliver surgical care efficiently. With lower overhead, limited bureaucracy, and streamlined care models, ASCs are inherently designed for high throughput.
Here are key strategies ASCs use to achieve superior OR turnover time reduction—and how hospitals can learn from them.
1. Culture of Accountability and Ownership
At many ASCs, every staff member understands their specific role in the turnover process. There’s no ambiguity about who cleans what, who restocks supplies, or who sets up the next case. This clarity is often missing in hospital ORs.
Real-World Example:
At SurgCenter Development, one of the largest ASC management companies in the U.S., surgical teams follow tightly choreographed turnover protocols. This culture of ownership allows many centers to turn rooms over in under 12 minutes.
Hospital Lesson:
Establish clear turnover roles and responsibilities using visual aids and checklists. Hold teams accountable by tracking individual and team metrics.
2. Standardized Turnover Protocols
ASCs often rely on Lean principles to standardize tasks and reduce waste. Everyone from the surgical tech to the environmental services (EVS) team follows a specific workflow.
Hospital Opportunity:
Hospitals should use Kaizen events or process mapping to streamline OR turnover workflows. Eliminate non-value-added steps, reduce variation, and implement standard operating procedures (SOPs).
Pro Tip: Post laminated SOPs in every OR, and review during daily huddles.
3. Team-Based Turnovers
Unlike hospitals where turnover responsibilities may fall disproportionately on certain team members (e.g., EVS or nursing), ASCs often use a team turnover model. In this approach, everyone contributes simultaneously, significantly reducing downtime.
Real-World Example:
At North Florida Surgery Center, the turnover team includes the circulator nurse, scrub tech, anesthesia tech, and even the surgeon in certain settings. This all-hands-on-deck model drives consistent sub-15-minute turnovers.
Hospital Application:
Create a multi-disciplinary OR turnover team that meets weekly to review turnover times, identify bottlenecks, and refine processes.
4. Efficient Scheduling and Pre-op Processes
Turnover time doesn’t start when the patient leaves the OR—it begins well before that. ASCs are masters of upstream efficiency, using patient flow modeling and predictive analytics to prep the next case in parallel.
Hospital Takeaway:
Improve coordination between pre-op, anesthesia, and OR teams. Use data from your EMR to stagger case preps and reduce idle time between cases.
5. Real-Time Communication Tools
ASCs often use simple but effective communication tools like light indicators, tablets, or even handheld radios to signal when an OR is ready for turnover. Hospitals relying solely on pagers or manual communication experience avoidable delays.
Case in Point:
At Surgery Partners-affiliated ASCs, real-time digital whiteboards show live turnover status, so the next team is ready to move immediately once a room becomes available.
Recommendation for Hospitals:
Invest in real-time location systems (RTLS) or turnover dashboards integrated with your EHR to track progress and signal readiness.
Metrics That Matter in OR Turnover Time Reduction
Effective measurement is key. Here are the most impactful metrics to track:
Metric | Description |
Average Turnover Time | From patient out to next patient in |
First Case On-Time Starts | Percentage of cases starting at scheduled time |
Total Daily Room Utilization | Time room is actively in use vs. idle |
Case Delay Reasons | Categorized and tracked for process improvement |
Tracking these metrics allows your leadership and surgical services team to identify trends and act decisively.
Common Barriers in Hospital OR Turnover—and How to Overcome Them
Even with the best intentions, hospitals face unique barriers. Here's how to tackle them:
1. Fragmented Communication
Hospital ORs often operate in silos—EVS doesn’t talk to anesthesia, or the charge nurse is out of the loop.
Solution:
Use daily OR huddles to align teams on the day's schedule, discuss anticipated bottlenecks, and clarify who’s doing what.
2. Insufficient Staff Engagement
Without buy-in from frontline staff, no improvement initiative will succeed.
Solution:
Use Kaizen methodology to involve staff in process redesign. Celebrate wins and reward innovation.
3. Poor Data Transparency
If staff don’t know how long turnovers take or what causes delays, improvement is impossible.
Solution:
Create visual dashboards in the OR lounge showing turnover time trends by team and shift. Include peer benchmarking when possible.
Case Study: Academic Medical Center vs. Local ASC
At a large academic medical center in the Midwest, average OR turnover time was 42 minutes. Despite high staffing levels and advanced equipment, delays stemmed from poor communication, unclear roles, and no standard protocol.
Across town, a freestanding ASC achieved a 13-minute average turnover using:
Clear role assignments
Real-time status boards
Team-based workflows
Daily performance reviews
The hospital, working with a Lean consultant, adopted ASC-inspired changes. Within 6 months, turnover times dropped by 28%, first-case on-time starts rose to 92%, and overtime spending fell by $1.1 million annually.
Implementing OR Turnover Time Reduction in Your Hospital
Here’s a step-by-step approach to apply these lessons:
Map the current turnover workflow using Lean tools like value stream mapping
Identify variation and eliminate non-essential steps
Standardize the process using checklists and visual guides
Pilot a team-based model in one OR
Implement daily huddles and end-of-day reviews
Track, publish, and review turnover metrics weekly
Create a feedback loop from OR staff to leadership
