Abstract
"Choosing Healthplans All Together" (CHAT) is a small group decision exercise designed to give the public a voice in priority setting in the face of unsustainable health care costs. It has been used for research, policy, and teaching purposes. Departments of insurance in various states in the United States have used CHAT to determine public opinion about what should be included in basic health insurance packages for the uninsured. Some municipalities have used it to assess public priorities for direct service delivery to the uninsured. Setting up the exercise requires substantial preparation, but the public finds it simple to use and understand.
