The Invited Commentary titled “Maryland’s All-Payer Health Reform—A Promising Work in Progress,” published in the February 2018 issue if JAMA Internal Medicine, did not include a comprehensive Conflicts of Interest Disclosure statement for author Joshua M. Sharfstein, MD. The full disclosure statement should read as follows: “Dr Sharfstein reports serving as Secretary of Maryland’s Department of Health and Mental Hygiene from 2011 through 2014, during which time he led the state’s efforts in the development of the global budgeting model; since 2015, he has consulted with large health systems for Sachs Policy Group, including explaining how global hospital budgeting works.” This article was corrected online.
