Summary
Physicians may recommend costly treatments that offer limited medical benefits, a phenomenon known as physician-induced demand. This behavior is influenced by treatment costs, benefits, and the diagnostic skill gap between doctors and patients.
Area of Science:
- Health Economics
- Medical Ethics
- Behavioral Economics
Background:
- The physician-patient relationship is a model for expert-client dynamics.
- Physicians diagnose illnesses and prescribe treatments, creating potential conflicts of interest.
Purpose of the Study:
- To model the economic incentives driving physician-induced demand.
- To identify factors influencing the level of socially inefficient treatment recommendations.
Main Methods:
- Economic modeling of the physician-patient interaction.
- Analysis of factors including treatment price, medical benefit, and relative diagnostic skills.
Main Results:
- Physicians may be incentivized to recommend treatments where costs exceed medical benefits.
- The degree of physician inducement depends on treatment characteristics and diagnostic expertise.
Conclusions:
- The study provides a framework for understanding physician-induced demand.
- The model generates testable hypotheses, with some supported by existing research.
