Given their ever-growing visibility, US value assessment initiatives warrant close attention. Therefore, the commentary by DuBois et al1 is to be welcomed. The piece raises a number of valuable points; above all that each value framework offered to date has strengths and limitations, and all have opportunities for improvement.

Most would agree that frameworks should be transparent and reproducible; that evaluations of interventions should be revisited over time; that there is merit in taking a broad perspective; that assessments should incorporate elements important to patients; and that a diversity of approaches reflecting the needs of diverse stakeholders should be considered. Finally, the article aptly raises various concerns (eg, about the lack of transparency, the absence of a societal perspective, and the need for more attention to patient preferences) with some of the existing frameworks. Arguments such as these should encourage the field to improve its methods
