Lternative ways of funding healthcare system

Dear Sir/ Madam,
i would like to have an up to date literature review of funding healthcare systems, focusing on the alternative ways.The references/sources should be published papers mainly at least at 70% of 2013&2014 (~25 different references).
Additionally, as ~25% of your work (3 pages), i would like to be have an analysis of OECDs health system accounts raising methodological inefficiencies from a point of view of the funding of healthcare system. Why is it not so good in some cases?
At your disposal for further clarifications.
