Governments across the world are struggling to pay for healthcare due to their ageing populations, the development of expensive new treatments and an increase in the number of people with chronic diseases, the World Health Organization (WHO) has said.

In countries where people pay directly for services at the point of care, healthcare bills are pushing 100 million people into poverty each year, its report added.

The WHO identifies three key areas where governments can make changes to improve healthcare: raising more funds, raising money more fairly and spending it more efficiently.

The report has been presented by WHO to a ministerial conference on health financing, hosted by the German Government, and is aimed at providing practical guidance to governments on ways to finance health care.
