Research conducted by the Norwegian University of Science and Technology (NTNU) has found that the expansion of private health insurance in Europe has led to a decline in overall public health. The study, which analyzed data from over 300,000 individuals across 20 countries from 2002 to 2022, indicates that while private health insurance can provide quicker access to healthcare for some, it negatively impacts the health of the broader population. Professor Pål Erling Martinussen noted that the increase in private insurance correlates with worse health outcomes, particularly for individuals with lower education levels, who are often more financially vulnerable. This demographic is more likely to report poor health in countries where private health insurance is prevalent. The findings suggest that the benefits of private health insurance for individuals do not compensate for the negative effects on public health as a whole. Consequently, the researchers advocate for European policymakers to implement measures to address these detrimental impacts and ensure equitable healthcare access for all citizens.
