The desirability of a condition versus the well being and worth of a person
研究发现，未处于某种状况的人对该状况的合意性评价，与处于该状况的人的实际福祉只有中等程度的相关，与这些人的价值几乎无关。用于QALY计算的单一健康状态评分无法同时表达这三种价值，健康经济学的历史和当前实践在这方面存在严重问题。
The desirability of a condition to people who are not in it themselves is only moderately correlated to the experienced well being of people with the condition and hardly correlated at all to the worth of those people. A single score for a health state, of the kind used in QALY calculations, cannot express all these three types of value. The history and current practice of health economics is highly problematic in this respect.
