In the Original Investigation titled “Risk Adjusting Survival Outcomes in Hospitals That Treat Patients With Cancer Without Information on Cancer Stage,”1 published online October 8, 2015, erroneous κ values were reported in 8 of the 12 categories of Table 2. The correct values also exceed the thresholds for high levels of agreement and thus do not alter the article’s conclusions. For 3- and 5-year mortality in the specified cancer types, the correct respective κ values are as follows: lung/bronchus, 0.84 and 0.84; prostate, 0.93 and 0.91; breast, 0.94 and 0.92; and colorectal, 0.89 and 0.90. This article was corrected online.
