title: A challenge to HMOs.
abstract: Outcomes research is needed to evaluate variations in medical care. When there is more than one reasonable option for treatment, Wennberg points out the need to base decisions on the patient's preferences. A shared decision-making model requires that patients be informed of their options, and empowered to make real choices. HMOs are presented with this challenge.
