Born equal? The distribution of government Medicare spending for children

Area of Science:

• Health Economics
• Public Health
• Child Development

Background:

• Equitable healthcare access is a key objective for national health systems.
• Understanding healthcare spending distribution is crucial for policy development.
• Early childhood is a critical period for development and future health outcomes.

Purpose of the Study:

• To assess the distribution of out-of-hospital government Medicare spending by household income in Australian children.
• To investigate trends in healthcare spending inequalities as children grow from infancy to adolescence.
• To identify specific areas of healthcare spending that exhibit income-related disparities.

Main Methods:

• Utilized the Longitudinal Study of Australian Children birth cohort linked with Medicare Benefits Scheme data.
• Included 4853 children recruited at ages 0-1 years, followed for 11 years (six waves).
• Assessed spending distributions using concentration indices, controlling for healthcare needs.

Main Results:

• Total government Medicare spending over 0-11 years favored higher-income families (concentration index 0.041).
• General practitioner care spending was equitable (concentration index 0.005).
• Specialist care (0.108) and diagnostics/imaging (0.088) spending favored higher-income families, particularly in early childhood.

Conclusions:

• Income-related inequalities in government Medicare spending exist, especially in the critical first few years of life.
• Disparities in specialist care spending were most pronounced in infancy and decreased with age.
• Findings highlight the need for policy attention to address early-life healthcare inequalities.
