Calculation of the clinician-surrogate prognostic discordance. In the post-meeting questionnaires, clinician and surrogate respondents independently recorded their prognostic estimates of the patient’s chances of hospital survival and return to independence 6 months later on a horizontal probability scale (0–100%), anchored on the right and left. These anchors were intended to aid subjects with limited numeracy. We calculated the clinician-surrogate prognostic discordance by subtracting the clinician’s prognostic estimate from the surrogate’s estimate. Clinician-surrogate discordance was defined as clinician-surrogate differences of at least 20% using the absolute clinician-surrogate discordance value. In the example shown, the surrogate estimated that the patient has a 90% chance of hospital survival (gray striped line), and the clinician estimated a 30% chance (black line); hence, the discordance score is 60. Since we utilized absolute values, the discordance score remained the same regardless of whether the clinician's estimate was more optimistic (greater) or less optimistic (smaller) than the surrogate's
