CMS's COVID-19 Data Included Required Information From the Vast Majority of Nursing Homes, but CMS Could Take Actions To Improve Completeness and Accuracy of the Data

The United States currently faces a nationwide public health emergency because of the COVID-19 pandemic. Federal regulations, effective May 8, 2020, required nursing homes to report COVID-19 information, such as the number of confirmed COVID-19 cases among residents, at least weekly to the Centers for Disease Control and Prevention’s (CDC’s) National Healthcare Safety Network. Each week, CDC aggregates the reported information and sends the data to the Centers for Medicare & Medicaid Services (CMS) for posting to the CMS website. These data are used to assist with national surveillance of COVID-19 in nursing homes and to support actions to protect the health and safety of nursing home residents. Our objective was to determine whether CMS’s COVID-19 data for nursing homes were complete and accurate.
