The National Health Insurance Model is a healthcare system where the government provides health insurance to all citizens. In this model, funding comes from taxes, and the government pays for medical services, ensuring that everyone has access to necessary care without direct charges at the point of service. Countries like Canada and Taiwan utilize this model, which combines elements of both public and private healthcare. While the government manages the insurance, healthcare providers can be private, allowing for a mix of public funding and private practice. This system aims to reduce costs and improve health outcomes for the population.
