Many types of health policies exist focusing on the financing of healthcare services to spread the economic risks of ill health. These include publicly funded health care (through taxation or insurance, also known as single-payer systems), mandatory or voluntary private health insurance, and complete capitalization of personal health care services through private companies, among others. The debate is ongoing on which type of health financing policy results in better or worse quality of healthcare services provided, and how to ensure allocated funds are used effectively, efficiently and equitably.
