Our study, “Universal Health Coverage in Massachusetts Did Not Change the Trajectory of Arthroplasty Use or Costs” published in Clinical Orthopaedics and Related Research® is an analysis of the State Inpatient Database (SID), a restricted-access, publicly available dataset that is maintained by the Agency for Healthcare Research and Quality (AHRQ). One of the provisions of the SID Data Use Agreement (DUA), which we signed when purchasing the data, is that no data observation involving less than or equal to 10 observations is to be published. This measure was put in place by AHRQ to protect individual patients’ privacy and to prevent the potential disclosure of personal information. In our manuscript, there are some tabulated cells in Table 1 that are in violation of this provision. This represents an oversight on my part and an inadvertent failure to comply with the DUA. For this, we apologize. We have provided a revised Table 1.

While I am fully confident that nothing in our paper could be used to identify individuals or their personal information, the fact remains that the disclosures are in violation of the AHRQ guidelines. We have therefore asked the editors of Clinical Orthopaedics and Related Research® to post an erratum that is in compliance with the AHRQ guidelines, and request that, going forward, authors cite the corrected version of our manuscript.
