To the Editor Mohanty and colleagues have published an excellent description of the updated American College of Surgeons (ACS) Risk Calculator, which now includes the outcome of “risk of discharge to postacute care.”1 In contrast to previous work,2 the updated ACS Risk Calculator provides estimates of nonhome discharge for patients undergoing hip and knee replacement, 2 very common procedures. The authors present this as strength of their study. This may not be the case.
