This cost explains why wealthy patients spend far more time in the hospital than poor patients (11.5 days versus 1.5 days per year) though they visit less frequently, and why the disparity in the length of hospital stays is growing.
這也就是雖然平均門診次數富人比窮人少，但平均住院日數卻是富人遠比窮人長（11.5 天 vs.1.5 天），而且落差越來越大的原因所在。
