Summary

This study found that supplier inducement equally affects dental demand and utilization. Understanding this impact on both is crucial for explaining dentist distribution, especially with payment systems influencing provider behavior.

Area of Science:

  • Health Economics
  • Dental Public Health
  • Healthcare Services Research

Background:

  • Supplier inducement is a known factor influencing healthcare utilization.
  • Its effect on demand versus utilization in dentistry requires further clarification.
  • Understanding these dynamics is key to addressing healthcare access and distribution.

Purpose of the Study:

  • To examine the relative impact of supplier inducement on dental demand versus utilization.
  • To analyze how dentist supply influences both the initiation and extent of dental visits.
  • To investigate the role of payment systems in shaping provider behavior and patient access.

Main Methods:

  • Utilized Tobit analysis to differentiate effects on demand and utilization.
  • Measured dentist supply using the population-to-dentist ratio in trade areas.

Related Experiment Videos

  • Analyzed data from a national sample of 1186 adult Norwegians.

    • Main Results:

    • Supplier inducement demonstrated a nearly equal effect on both dental demand and utilization.
    • The payment system, linking service items to average performance time, may contribute to this finding.
    • Dentist income appears independent of focusing on check-ups versus treatments.

    Conclusions:

    • Supplier induced demand is a significant factor alongside supplier induced utilization.
    • These combined factors are essential for understanding the unequal distribution of dental providers.
    • Policy considerations should address both demand and utilization effects of supplier inducement.
