This is a very general video by the WHO that comments on the need for countries to develop health care systems that they, and their citizens, can afford.
“Governments worldwide are struggling to pay for health care. As populations get older, as more people suffer chronic diseases, and as new and more expensive treatments appear, health costs soar. Every year, health bills push 100 million people into poverty each year. WHO’s report ‘On the Path to Universal Coverage’ takes evidence from all over the world to show how all countries, rich and poor, can adjust their health financing mechanisms so more people get the health care they need.”

If universal access is the goal, health care financing presents a major hurdle. Similar challenges and possible solutions are explored in a recent editorial in Health and Human Rights: http://www.hhrjournal.org/index.php/hhr/article/view/406/629.
