Summary

Optimizing outpatient staffing requires careful consideration of physician mix. Discrete-event simulation using Coloured Petri Nets (CPN) identified that three senior staff physicians optimally support ten resident physicians for efficient patient flow.

Area of Science:

  • Healthcare Operations Research
  • Medical Education Systems
  • Simulation Modeling

Background:

  • Outpatient settings involve a mix of experienced and novice resident physicians supervised by senior staff.
  • System performance is contingent upon the number of available senior staff physicians for supervision.
  • Optimizing human resource allocation is crucial for efficient outpatient operations.

Purpose of the Study:

  • To determine the optimal number of senior staff physicians needed for a given number of resident physicians in an outpatient setting.
  • To enhance overall system performance and patient throughput through resource optimization.
  • To leverage discrete-event simulation for informed staffing decisions.

Main Methods:

  • Utilized timed Coloured Petri Nets (CPN), a discrete-event simulation formalism.

  • Modeled outpatient settings considering concurrency and resource sharing dynamics.
  • Identified optimal resource mix (senior staff to resident physician ratio) for system efficiency.

    • Main Results:

    • With 10 resident physicians, 2 senior staff physicians yield 42-52 patients/5-hr period.
    • Increasing to 3 senior staff physicians substantially improves performance to 49-56 patients/5-hr period.
    • A fourth senior staff physician offers minimal additional performance gain (50-57 patients/5-hr period).

    Conclusions:

    • Coloured Petri Nets (CPN) offer a flexible simulation environment for outpatient settings.
    • CPN analysis aids in assessing the impact of staffing changes on system performance.
    • Simulation-based insights support informed resource allocation decisions in healthcare.
