映射提供了一种统计算法，允许在临床研究中估计效用，并因此计算QOLS，其中未实施基于偏好的测量。利用了映射文献的综述。映射要求估计和研究数据集之间的人群相似，目标和基础测量之间的高度重叠是可取的。国家健康和临床优化研究所认为映射是一种提供效用信息的方法。围绕映射的问题包括测量的描述系统，适当的计量经济学方法和模型规格。有必要进一步研究过度的问题，预测严重的健康状况和不确定性周围的估计效用分数。映射仍然是一个重要的研究领域，为经济评估，特别是验证映射功能。
Mapping provides a statistical algorithm that allows the estimation of utilities and consequently calculation of QALYs in clinical studies where preference-based measures are not implemented.Reviews of the mapping literature were utilized.Mapping requires similar populations between the estimation and study data sets, with a high degree of overlap between the target and base measures being desirable. The National Institute for Health and Clinical Excellence recognizes mapping as a method to provide utility information.Issues surrounding mapping include the descriptive system of the measure, the appropriate econometric method and model specification.There is a need for further research into the issue of over-prediction for severe health states and uncertainty around the estimated utility scores.Mapping continues to be an important area of research for economic evaluation, in particular validation of mapping functions.
