The expected utility framework underlies much research in medical decision making. Because the framework requires decisions to be decomposed into probabilities of states and the values of those states, researchers have investigated the two components separately from each other and from patients' actual decisions. The authors propose that it would be productive to focus more research on the relationships among risk perceptions, outcome valuations, and choices in the same decision makers. They outline exploratory analyses based on two existing national surveys, the Medical Expenditure Panel Survey and the Joint Canada/United States Survey of Health.
期望效用框架是医学决策研究的基础。由于该框架要求决策分解为状态的概率和这些状态的价值，研究人员已经分别从研究和患者的实际决策两个方面对这两个组成部分进行了研究。作者提出，集中更多的研究精力于同一决策者的风险感知、结果评估和选择之间的关系，将会富有成效。他们根据两项现有的全国性调查，即《医疗支出面板调查》和《加拿大/美国联合健康调查》，概述了探索性分析。
