An amazing collection of data has been performed by van Doorslaer et al. in their 2007 Health Economics paper “Catastrophic Payments for Health Care in Asia.” For 14 Asian countries, the authors categorize all charged services, free services, and income-related fee waivers. Further the paper examines the frequency and magnitude of out-of-pocket payments for medical care in each nation. Just three of these statistics are described below.
