Summary

Competition among Australian general practitioners (GPs) influences follow-up consultation recommendations for some conditions. Further research is needed to confirm these findings on supplier-induced demand.

Area of Science:

  • Health Economics
  • General Practice
  • Healthcare Management

Background:

  • Understanding the impact of competition on healthcare provider behavior is crucial for policy development.
  • Previous studies on general practitioner (GP) competition have methodological limitations.

Purpose of the Study:

  • To investigate the effect of competition on Australian GP consultation behavior.
  • To determine if GP density influences the recommendation of follow-up consultations.
  • To explore variations in competitive effects across different medical conditions.

Main Methods:

  • Utilized a random effects probit model within a multilevel modeling framework for robust estimation.
  • Incorporated data on GP and practice characteristics.
  • Employed actual GP consultations, disaggregated by medical condition, as the unit of observation.

Main Results:

  • GP density was found to influence follow-up recommendations for one of the four analyzed medical conditions.
  • The study provides preliminary evidence on the relationship between GP competition and consultation behavior.

Conclusions:

  • The density of general practitioners impacts follow-up decisions for specific medical conditions.
  • Further investigation is required to conclusively link these findings to competition effects and supplier-induced demand.
