The primary outcome was immediate survival with any return of spontaneous circulation (ROSC) and the secondary outcome was 30-day survival and neurological outcomes.

Outcomes of patients ages 14 and older with severe COVID-19 pneumonia after in-hospital cardiac arrest (IHCA) over a 40-day period were retrospectively evaluated. Data between January 15 and February 25, 2020, for all cardiopulmonary resuscitation (CPR) attempts for IHCA that occurred in Union Hospital, a tertiary teaching hospital in Wuhan, China which was designated for patients with severe COVID-19, were collected.

Patients were stratified according to survival status at 30 days
