Tracking universal health coverage: First global monitoring report

Joint WHO/World Bank Group report, June 2015
This report is the first of its kind to measure health service coverage and financial protection to assess countries’ progress towards universal health coverage.
It shows that at least 400 million people do not have access to one or more essential health services and 6% of people in low- and middle-income countries are tipped into or pushed further into extreme poverty because of health spending. 
This first-of-its-kind report looks at global access to essential health services and promotes thirteen indicators for monitoring health intervention coverage, including cataract surgical coverage.
