In the Original Investigation, “Low-Value Care at the Actionable Level of Individual Health Systems,” which was published online first on September 27, 2021, and in the November 2021 issue of JAMA Internal Medicine, errors occurred. The calculation for providing antibiotics for upper respiratory infections (URIs) was incorrect. The denominator for this measure was too high, leading to an underestimate of the prevalence of antibiotics for URIs. As explained in a Letter, while this error was present in only 1 of the 41 measures, because the measure for antibiotics for URIs was included in a composite measure of low-value care, the results based on the composite calculation were in error and have been corrected. In addition, the percentage of attributed beneficiaries of non-White race shifted from significant to nonsignificant. Corrections to address these errors do not affect other aspects of the study’s interpretations and conclusions. The following sections of the article have been corrected: Key Points, Abstract, Results and Discussions sections of the main text, Table 2, Figures 1 to 3, eTable 5 in Supplement 1, and the Excel file of eTable 4 in Supplement 2. This article has been corrected.
