This study introduces a novel method using spline functions to analyze seasonal patterns in high-frequency health data. This approach helps healthcare managers make better decisions by understanding periodic variations in demand.

Area of Science:

  • Health services research
  • Statistical modeling
  • Time series analysis

Background:

  • Seasonal variations significantly impact healthcare service organization and demand.
  • Effective management requires understanding short-term fluctuations in medical data.
  • Analyzing seasonal patterns in high-frequency health data is crucial for operational efficiency.

Purpose of the Study:

  • To propose novel procedures for analyzing the seasonal component in high-frequency health data.
  • To develop adaptable spline functions within a structural model for this analysis.
  • To capture deterministic and stochastic periodic variations parsimoniously.

Main Methods:

  • Utilizing spline functions embedded within a structural model.
  • Developing adapted spline formulations for high-frequency data.

    • Main Results:

    • The proposed method effectively captures seasonal variations in health service demand.
    • The procedures successfully identify simultaneous seasonal patterns with differing periods.
    • The approach offers a parsimonious way to model complex periodicities.

    Conclusions:

    • The developed spline-based methodology provides a powerful tool for analyzing seasonal health data.
    • This approach enhances the understanding of periodic variations in healthcare demand.
    • The findings support improved health service organization and management decisions.
