In Reply We did not argue that ICU admission directly harms patients with low illness severity. Our Viewpoint acknowledged a small potential benefit of close observation in the ICU for these patients. Therefore, we did not use the term supplier-induced demand, which, as Mr Friedman correctly notes, implies but does not require a lack of marginal benefit.1 Instead, we argued that this small potential benefit does not justify the high costs of building and maintaining ICUs.
