n an interview, Aris Sissouras, Professor of Operations Research, University of Patras, explains why Greece's health reform may fall short of expectation. Their current health policy and any changes to the health sector are determined mainly by the crisis and dictated by the memoranda of the Troika. The fact is that Greece has taken out loans and that obliges them to fulfil certain conditions. While there is unease about this situation in Greece, a large part of their society recognizes that the health-care system had reached the point of unsustainability and was in urgent need of reform. Although Greece created a national health system in 1983, it is a mixed system of health-care services comprising a large public sector: the National Health System and the social health insurance funds; and a private health care sector, which grew as a result of the public sector's failure to undergo the reforms of the original law. He's one of those who believe that the crisis has provided Greece with a window of opportunity.
