Operations research (OR) provides a rational solution for scheduling resident duty hours, moving beyond trial-and-error methods. This computer-aided approach ensures compliance with regulations and service needs.

Area of Science:

  • Medical Education
  • Operations Research
  • Healthcare Management

Background:

  • The 80-hour resident work week necessitates structured duty hour scheduling.
  • Current scheduling methods often rely on empirical trial-and-error.
  • This presents a complex scheduling problem analogous to airline operations.

Purpose of the Study:

  • To investigate the application of operations research (OR) principles to resident duty hour scheduling.
  • To develop a rational, algorithm-based solution for optimizing resident schedules.
  • To test the hypothesis that OR can provide an effective scheduling framework.

Main Methods:

  • Formulated institution-specific constraints for 56 residents across 4 hospitals.
  • Incorporated Residency Review Committee (RRC) rules and surgical service requirements.

  • Utilized mixed integer programming with the ILOG software suite.

    • Main Results:

    • Generated an integer programming solution for the resource-constrained assignment problem.
    • The model involved 30,900 variables and 12,443 constraints, with a 25.9-hour computer run-time.
    • Produced weekly schedules satisfying RRC regulations and service demands, with duty hours between 64-80 per week.

    Conclusions:

    • Operations research is a viable and robust method for scheduling resident work hours.
    • This OR approach can adapt to changes in resident numbers, service needs, and rotations.
    • The study demonstrates a rational, data-driven alternative to traditional scheduling.
