We first establish a framework for discussing and comparing healthcare systems: using data taken from the World Health Organization, we use this framework to rank the systems of the U.S., Sweden, and Nigeria. Our rankings agree with previous studies. Using a probabilistic model incorporating economic factors, we inves- egy to improve its rank. Our results indicate that the U.S. shouldppat. tigate the effects of various changes to the U.S. system and develop a st more emphasis on the prevention of illness, and it should shift toward a more-centralized system so as to make care more accessible to lower- and middle-class individuals Introduction While the U.S. has historically spent more per capita on healthcare than most other countries, the U.S. has seen little improvement in healthcare, and even the U.S. Congress admits that the system is far from the best [1993].
