Small area variations in Finnish hospital use are driven by organizational factors, not demographics. Coordinate-based mapping offers a superior method for visualizing healthcare utilization and mortality data.

Area of Science:

  • Health Services Research
  • Medical Informatics
  • Public Health

Background:

  • National hospital discharge registers in Finland from 1985 and 1988 were analyzed.
  • Small area variations in hospital utilization were observed across 21 Finnish hospital districts.
  • Demographic and epidemiological factors did not explain these variations.

Purpose of the Study:

  • To develop an efficient data processing system for analyzing large patient datasets.
  • To present healthcare utilization data in an understandable format, such as maps.
  • To investigate the causes of regional variations in hospital utilization.

Main Methods:

  • Analysis of Finnish national hospital discharge registers.
  • Development of a data processing system for handling one million patient records.

  • Utilizing coordinate-based mapping by linking discharge/mortality data with exact addresses.
  • Mapping independent of administrative boundaries.

    • Main Results:

    • Hospital utilization variations are primarily attributed to organizational factors.
    • Coordinate-based mapping effectively demonstrates regional variations in healthcare utilization and mortality.
    • This mapping method overcomes limitations of traditional statistical tables and small administrative unit maps.

    Conclusions:

    • Organizational factors significantly influence regional disparities in hospital use.
    • Coordinate-based mapping is a powerful tool for analyzing and visualizing health care data.
    • The developed method is suitable for annual analysis of hospital use in Finland.
