Area of Science:

  • Healthcare Operations Research
  • Anesthesiology Staffing Optimization
  • Predictive Analytics in Healthcare

Background:

  • Operating room schedules are often disrupted by cases running longer than anticipated.
  • This unpredictability leads to overtime for first-shift anesthesiologists and impacts staffing efficiency.
  • Effective strategies are needed to manage anesthesiologist assignments for late-running operating rooms.

Purpose of the Study:

  • To develop and evaluate a relief strategy for assigning second-shift anesthesiologists to late-running operating rooms.
  • To minimize overtime for first-shift anesthesiologists using historical case duration data.
  • To assess the cost-effectiveness of the proposed strategy compared to real-time monitoring.

Main Methods:

  • Developed a statistical method analyzing historical case durations from surgical services information systems.

  • Estimated the expected remaining hours for ongoing surgical cases.
  • Compared overtime hours under the proposed strategy versus a theoretical minimum with perfect information.

    • Main Results:

    • The relief strategy resulted in 3.4% to 4.9% more overtime for first-shift anesthesiologists compared to the theoretical minimum.
    • Supplementing the strategy with real-time tracking systems offered minimal additional savings in staff hours.
    • The strategy proved effective in managing anesthesiologist assignments for late cases.

    Conclusions:

    • A relief strategy using historical case duration analysis is effective for minimizing anesthesiologist staffing costs.
    • This predictive approach offers a practical solution for managing operating room staffing challenges.
    • The reliance on existing operating room information systems makes this strategy readily implementable.
