To the Editor We believe that the Viewpoint by Drs Katz and Hawley1 on shared decision making inaccurately states its premise and misrepresents the evidence about its effects. Katz and Hawley’s position is that the evidence for the effect of shared decision making on medical costs and use is inadequate. In their review of a randomized trial of shared decision making by 2 of us,2,3 they suggested that the large observed decreases in medical and surgical admissions and the associated reduction in costs in the intervention group were a result of clinician-directed decisions rather than patient involvement.
