对医疗保健的需求增加，加上资源有限，意味着必须就稀缺的医疗保健资源的分配做出决定。本文探讨了如何使用联合分析 (CA) 来帮助这一决策过程。展示了如何使用该技术来估计属性之间的边际替代率、支付意愿（WTP）（如果成本作为属性）以及不同提供服务方式的总体效用得分。该技术用于考虑女性对治疗月经过多的两种外科手术的偏好：子宫切除术和保守性手术。结果表明，保守性手术优于子宫切除术，因为前者的效用得分较高，并且保守性手术而不是子宫切除术的边缘 WTP 为 7593。还显示了 CA 的内部有效性。结论是，CA 对于政策制定者来说是一个潜在有用的工具。然而，在该技术成为经济评估中的既定工具之前，需要解决许多方法论问题。
The increased demand for health care, coupled with limited resources, means that decisions have to be made concerning the allocation of scarce health care resources. This paper considers how conjoint analysis (CA) can be used to aid this decision making process. It is shown how the technique can be used to estimate marginal rates of substitution between attributes, willingness to pay (WTP) if cost is included as an attribute and overall utility scores for different ways of providing a service. The technique is applied to consider women's preferences for two surgical procedures in the treatment of menorrhagia: hysterectomy and conservative surgery. The results suggest conservative surgery is preferred to hysterectomy, as indicated by higher utility scores for the former and a marginal WTP of 7593 to have conservative surgery rather than hysterectomy. The internal validity of CA was also shown. It is concluded that CA is a potentially useful instrument for policy makers. However, numerous methodological issues need addressing before the technique becomes an established instrument within economic evaluations.
