    Area of Science:

    • Health Services Research
    • Medical Informatics
    • Geographic Information Systems

    Background:

    • Cancer patient referral patterns are crucial for understanding healthcare access and delivery.
    • Analyzing geographic trends in healthcare utilization can reveal important insights into service accessibility.
    • Previous methods for mapping referral data were often costly and time-consuming.

    Purpose of the Study:

    • To introduce and evaluate the FLOWMAP computer program for analyzing cancer patient referral patterns.
    • To examine the geographic distribution and trends of cancer patient referrals in western Washington between 1974 and 1978.
    • To demonstrate the cost-effectiveness and utility of FLOWMAP for health services research.

    Main Methods:

    • Utilized an interactive graphic computer program, FLOWMAP, to process origin-destination data for cancer patient referrals.

  • Generated various map types to visualize referral patterns among 13 counties over a 5-year period.
  • Compared the cost-efficiency of FLOWMAP-generated maps with traditional manual mapping methods.

    • Main Results:

    • Mapped referral patterns for over 7000 cancer patients, highlighting significant geographic components.
    • Demonstrated a trend towards decentralization in cancer care delivery within the studied region and timeframe.
    • Showcased the ease of use and cost-effectiveness of FLOWMAP, estimating savings of 1/30 to 1/50 compared to manual methods.

    Conclusions:

    • FLOWMAP is an effective and economical tool for analyzing geographic patterns in healthcare referrals.
    • The study identified a significant decentralization of cancer care in western Washington between 1974 and 1978.
    • FLOWMAP has potential applications for various health services research questions beyond cancer patient referrals.
