Second opinion programs proliferated in the 1970s, and most of these were voluntary programs. Until more complete evaluations of voluntary and mandatory programs are done, it seems likely that second opinion programs will continue to be on a voluntary basis. Second opinion programs have been shown to identify potential surplus surgery and are designed to contain costs.
第二种意见项目在20世纪70年代迅速增加，其中大部分是自愿性项目。在对自愿性和强制性项目进行更全面的评估之前，第二种意见项目似乎很可能会继续保持自愿性质。第二种意见项目已被证明可以识别潜在的过度手术，并旨在控制成本。
