Co-occurrence of confirmed COVID-19 and Type 2 diabetes mellitus among adult inpatient admissions, 2020 National Hospital Care Survey (309766)

Keywords: COVID-19, hospital, Type 2 diabetes mellitus, length of stay

In late 2020, the National Center for Health Statistics sought to examine the impact of COVID-19 on hospital care in the United States using early release data from the National Hospital Care Survey (NHCS). The NHCS collects a year’s worth of electronic health records or UB-04 billing data from inpatient and emergency department encounters from sampled hospitals to describe patterns of health care delivery and utilization. A non-nationally representative selection of hospitals from the NHCS provided timely UB-04 data to examine average length of stay (ALOS) among adults with confirmed COVID-19 and Type 2 diabetes mellitus. Between March 18 and December 29, 2020, 63 hospitals submitted 52,978 inpatient admissions with a diagnosis of confirmed COVID-19. Twenty-six percent had co-occurring Type 2 diabetes mellitus. Analyses will include ALOS by intubation or ventilator use and in-hospital mortality status.
