During the first decade of this century, health reforms have advocated for universal health coverage in those countries with social health insurance based on contributions. This is a strong trend that needs to be evaluated. A recent article describes in detail these changes and says:
Contrary to some expectations, SHI in Europe has further expanded toward universal coverage, with access to health care considered a right based on either direct or indirect financial contributions. Indeed, Germany is now the only example in Europe where groups of the population can opt out from the main insurance system. And, since 2009, the overall population is required to be covered by either social or private insurance.
