Purpose: The purpose of this study was to demonstrate the feasibility and results of ascertaining Medicare enrollees' priorities for insured medical benefits. Design and Methods: Structured group exercises were conducted with Medicare enrollees from clinical and community settings in central North Carolina. By participating in a decision exercise, CHAT: Choosing Healthplans All Together, individuals and groups chose medical benefits within the constraints of a monthly Medicare + Choice premium. The acceptability of the exercise and the resulting benefit package were assessed. Results: Ten groups (121 individuals) made trade-offs that involved the selection of more tightly managed care in order to add pharmacy, dental, and long-term care benefits. All were willing to forgo experimental therapy; 7 groups gave priority to insuring the uninsured. Participants found the exercise overwhelmingly acceptable and were willing to abide by their groups' choices. Implications: Medicare enrollees are able to come to consensus about financially constrained benefit packages that may be useful in reform of the Medicare program.
