as well as other conditions for which the evidence appeared much less persuasive. The committee then assigned working groups to review and summarize the published medical literature. The committee also sought expert advice from people who were not committee members, primarily through presentations at subsequent committee meetings. At several points, the working groups presented their assessments to the entire committee. These presentations included an overall assessment of the efficacy of nutrition-based therapy in the elderly, as well as practical aspects of implementation (e.g. Who is qualified to implement the therapy—a highly skilled professional or a variety of general health professionals? What is the appropriate setting? What number of contacts is required; and so forth). The committee then considered the costs of nutrition-based therapy and identified potential cost offsets. Methods pertaining to the cost analyses are presented separately in chapter 14.
