Area of Science:

  • Health Services Research
  • Medical Ethics
  • Health Equity

Background:

  • Publicly funded healthcare systems aim to provide care based on need.
  • Evidence suggests bias exists in healthcare utilization.
  • Assessing healthcare fairness requires examining treatment decisions and clinical judgment.

Purpose of the Study:

  • To define and differentiate horizontal and vertical equity in healthcare distribution.
  • To explore the conditions necessary to demonstrate unfair treatment decisions.
  • To discuss methodological challenges in identifying bias in clinical judgment.

Main Methods:

  • Conceptual analysis of healthcare distribution principles.
  • Definition of horizontal equity (equal use for equal need).
  • Definition of vertical equity (unequal use for unequal need).

Main Results:

  • Demonstrates that equal use for equal need (horizontal equity) does not guarantee unequal use for unequal need (vertical equity).
  • Highlights that clinical judgment can be influenced by patient prejudice.
  • Discusses the methodological difficulties in proving biased clinical decision-making.

Conclusions:

  • Fairness in healthcare requires both equal treatment for equal need and appropriate differential treatment for unequal need.
  • Proving bias in clinical decisions is methodologically challenging.
  • Methods for examining bias-driven healthcare inequalities are described.
