Optimizing OR Efficiency & Reducing Patient Wait Times
1. The Engagement Request
A hospital system faced operational inefficiencies in its Operating Room (OR) scheduling and patient flow, leading to underutilized OR block time, longer patient wait times, and scheduling bottlenecks. Surgeons experienced delays in accessing ORs, while patients faced extended preoperative wait times, impacting both provider satisfaction and overall hospital throughput. Leadership sought a data-driven approach to optimize OR block utilization and streamline the transition from Pre-Op to OR to improve efficiency across the system.
2. The Solutions
To enhance OR efficiency and reduce patient wait times, we conducted a comprehensive analysis of patient flow, scheduling, and resource allocation.
Operational Analysis & Bottleneck Identification
​
-
Conducted workflow observations and data analysis to identify inefficiencies in the patient journey from Pre-Op to the OR.
-
Mapped out OR utilization patterns, identifying idle block times, inefficient case turnover processes, and scheduling inconsistencies.
-
Collected input from surgeons, anesthesiologists, nurses, and schedulers to pinpoint operational pain points.
Process Optimization & Scheduling Adjustments
​
-
Implemented a real-time tracking system to monitor case start times, delays, and patient handoffs between Pre-Op and OR teams.
-
Recommended pre-surgical workflow standardization, ensuring patients were fully prepped and ready for transfer before OR slots became available.
-
Adjusted block time allocation based on surgeon utilization trends, ensuring higher efficiency without compromising case flexibility.
Performance Monitoring & Sustained Improvement
​
-
Developed customized OR efficiency dashboards to provide real-time insights for scheduling teams and surgical departments.
-
Established regular performance reviews to ensure continued optimization and adherence to revised workflows.
-
Provided leadership with long-term recommendations to maintain efficiency gains and further refine OR block scheduling models.
3. The Processes
These two methodologies—Lean Management for process optimization and Decision Matrix Analysis for structured evaluation—ensured that the FQHC selected the most effective, compliant, and scalable pharmaceutical software solution.
Lean Six Sigma (LSS) for Operating Room Efficiency
​
Lean Six Sigma (LSS) is a structured methodology that combines Lean principles (waste reduction) with Six Sigma (variation reduction) to drive efficiency and process standardization.
​
Application to OR Optimization:
-
Define & Measure (Identifying Inefficiencies)
-
Mapped out patient flow from Pre-Op to OR, identifying scheduling bottlenecks and underutilized block time.
-
Collected time-stamped data on case start times, delays, and handoffs to quantify inefficiencies.
-
-
Analyze & Improve (Optimizing Scheduling & Workflow)
-
Used root cause analysis (RCA) to address key inefficiencies in turnover times and scheduling misalignments.
-
Implemented workflow standardization to improve pre-surgical readiness, reducing idle OR time.
-
-
Control (Sustaining Efficiency Gains)
-
Developed real-time dashboards and tracking systems for ongoing OR performance monitoring.
-
Established a continuous feedback loop with surgical teams to refine scheduling models and enhance throughput.
-
Outcome: Increased OR block efficiency by 7%, reduced patient wait times by 12%, and improved case throughput—all without additional OR resources.
Theory of Constraints (ToC) for OR Flow Optimization
​
The Theory of Constraints (TOC) focuses on identifying and eliminating bottlenecks that limit overall system performance.
​
Application to OR Optimization:
-
Identify the Constraint (Pre-Op to OR Bottlenecks)
-
Analyzed where delays occurred in the surgical workflow, pinpointing Pre-Op preparation and case turnover as critical constraints.
-
-
Exploit & Subordinate (Streamlining Patient Flow & Scheduling)
-
Standardized pre-surgical workflows to ensure patients were fully prepped before OR slots opened.
-
Adjusted block time allocation based on surgeon utilization data to maximize throughput.
-
-
Elevate & Repeat (Sustaining Efficiency Improvements)
-
Integrated real-time scheduling adjustments to dynamically address emerging bottlenecks.
-
Established a structured performance review process to continuously refine OR utilization.
-
Outcome: Reduced patient transfer delays, improved OR case throughput, and enhanced scheduling predictability for surgeons and staff.
4. The Results
OR Block efficiency increased by 7%, enabling surgeons to optimize their schedules and reduce idle time.
Patient wait times from Pre-Op to OR decreased by 8%, improving patient experience and surgical team workflow.
Turnover time between cases improved, leading to higher daily case volumes without requiring additional OR resources.
Improved surgeon and staff satisfaction, reducing friction in scheduling and increasing overall surgical department productivity.
