    Summary

    This study developed a computer model to predict x-ray department wait times. The model accurately predicted that faster film processing reduces patient wait times, improving efficiency.

    Area of Science:

    • Radiology and Medical Imaging
    • Operations Research
    • Healthcare Management

    Background:

    • X-ray departments face challenges managing patient flow and resource allocation.
    • Optimizing operational efficiency is crucial for reducing patient wait times and improving service delivery.

    Purpose of the Study:

    • To design and validate a computer simulation model for predicting the impact of changes in workload and resources within an x-ray department.
    • To assess the effect of specific operational changes, such as film processing speed and staffing levels, on patient waiting times.

    Main Methods:

    • Development of a discrete-event simulation model for an x-ray department.
    • Utilizing the model to generate histograms of patient waiting times under various scenarios.
    • Introducing simulated changes in film processing speed, number of cubicles, and radiographer availability.

    Main Results:

    • The simulation model successfully predicted patient waiting times based on departmental resources and workload.
    • Histograms clearly illustrated the impact of changes in processing speed and staffing on wait times.
    • A significant reduction in patient waiting times was predicted with the introduction of a faster film processor.

    Conclusions:

    • Computer simulation is a valuable tool for predicting and optimizing x-ray department operations.
    • Implementing faster film processing technology can practically reduce patient waiting times.
    • The model provides a framework for evaluating other resource allocation strategies in radiology departments.
