Optimizing operating room (OR) utilization is crucial for efficiency. Simulations show that achieving 85% to 90% OR utilization balances operational goals with minimizing patient delays and staff overtime.

Area of Science:

  • Healthcare Management
  • Operations Research

Background:

  • Economic factors necessitate high operating room (OR) utilization.
  • The optimal OR utilization rate remains undefined, impacting efficiency and patient flow.

Purpose of the Study:

  • To define the optimum utilization of an operating room (OR) through simulation.
  • To identify the utilization threshold that balances efficiency with operational goals.

Main Methods:

  • Developed a simulation model of an OR.
  • Established operational targets: cases starting within 15 minutes of schedule and ending within 15 minutes of the scheduled day's end.

Main Results:

  • The highest achievable OR utilization without delays or late finishes is between 85% and 90%.

  • Increased variability in case duration reduces the achievable utilization within the defined targets.

    • Conclusions:

    • Operating room utilization exceeding 85% to 90% results in patient delays and staff overtime.
    • Enhanced OR efficiency may compromise patient convenience.
