Rational decision making in medicine: Implications for overuse and underuse

Area of Science:

• Health Economics
• Decision Theory
• Health Services Research

Background:

• Healthcare systems face challenges with suboptimal outcomes despite high spending.
• Overuse (overtesting/overtreatment) and underuse (undertesting/undertreatment) of services are significant contributors to poor quality.
• Low-quality decision-making, violating rationality criteria, drives these issues and accounts for over 80% of healthcare expenses.

Purpose of the Study:

• To analyze healthcare overuse and underuse through the lens of rational choice theory.
• To demonstrate how different decision theories yield varying definitions of rationality.
• To emphasize the need for context-specific theoretical frameworks in evaluating healthcare appropriateness.

Main Methods:

• Application of rational choice theory to analyze decision-making in healthcare.
• Comparative analysis of different theoretical frameworks for assessing rationality.
• Illustrative examples to demonstrate the impact of theoretical choices on policy and individual decisions.

Main Results:

• The definition of rational decision-making in healthcare is contingent on the chosen theoretical framework.
• Selecting the appropriate theoretical framework is crucial for determining the "appropriateness" of healthcare interventions.
• The choice of framework significantly influences healthcare policy and individual decision-making processes.

Conclusions:

• Addressing healthcare overuse and underuse requires a specific theoretical framework tailored to clinical situations.
• The measurement of healthcare quality and its link to financing must consider the underlying decision-making theories.
• A nuanced understanding of rationality is essential for improving healthcare delivery and outcomes.
