Data Source Changes Due to the COVID-19 Pandemic

Due to the coronavirus disease of 2019 (COVID-19) pandemic, many data sources modified their data collection methodology in 2020. The hospital, home health care, and hospice Consumer Assessment of Healthcare Providers and Systems data were collected only for the last two quarters of 2020. The Quality and Safety Review System data were only collected for the last quarter of 2020.

For Outcome and Assessment Information Set data, the Centers for Medicare & Medicaid Services (CMS) granted a temporary exemption for reporting home health care data to CMS through June 30, 2020. The data collection for the 2020 National Survey on Drug Use and Health and 2020 National Health Interview Survey were also modified due to the pandemic.
