    Area of Science:

    • Healthcare Management
    • Operations Research
    • Statistical Modeling

    Background:

    • Accurate patient census data is crucial for hospital operations.
    • Forecasting systems require understanding patient census patterns.
    • Existing methods may not fully capture meal-specific census variations.

    Purpose of the Study:

    • To identify functional relationships between patient census and official midnight census.
    • To inform the design of a statistical menu item forecasting system.
    • To analyze patient census data for three meals (breakfast, lunch, supper) against the midnight census.

    Main Methods:

    • Graphical analysis of patient census data.
    • Analysis of variance (ANOVA) to compare meal census with midnight census.
    • Appraisal of three distinct forecasting system design options.

    Main Results:

    • Identified reliable, predictable patterns in patient census data.
    • Established functional relationships between meal times and midnight census.
    • All three forecasting design options yielded identical quantity predictions.

    Conclusions:

    • Patient census data exhibits patterns suitable for mathematical forecasting models.
    • A statistical forecasting system can be effectively designed based on identified relationships.
    • The complexity of the forecasting model did not significantly impact prediction accuracy in this study.
