In this issue of JAMA, Allen and colleagues1 report findings from a provocative study that identifies a disconnection between patient-predicted and model-predicted life expectancy among ambulatory patients with heart failure. In so doing, this study provides challenges to evaluating the need to know prognosis, communicating prognostic information, and anticipating the consequences of such information for a patient with heart failure.
Allen et al used the Seattle Heart Failure Model (SHFM)2 to estimate life expectancy in the setting of stable ambulatory chronic heart failure in a small single-center tertiary care patient population and then determined the actuarial-predicted life expectancy in the absence of any known disease. To determine the patient's own assessment of survival, a de novo questionnaire was constructed to determine life traits and perceptions, with the scores acquired using a visual analog scale. Questions to assess depression (using a modified Beck Depression Inventory) and . . . [Full Text of this Article]
