Aim: To estimate the mortality rate, the rate of return of spontaneous circulation (ROSC) and survival with favorable neurological outcome in patients with COVID-19 after in-hospital cardiac arrest (IHCA) and attempted cardiopulmonary resuscitation (CPR). Methods: PubMed, EMBASE, Web of Science, bioRxiv and medRxiv were surveyed up to 8th February 2021 for studies reporting data on mortality of patients with COVID-19 after IHCA. The primary outcome sought was mortality (in-hospital or at 30 days) after IHCA with attempted CPR. Additional outcomes were the overall rate of IHCA, the rate of non-shockable presenting rhythms, the rate of ROSC and the rate of survival with favorable neurological status. Results: Ten articles were included in the systematic review and meta-analysis, for a total of 1179 COVID-19 patients after IHCA with attempted CPR. The estimated overall mortality rate (in-hospital or at 30 days) was 89.9% (95% Predicted Interval [P.I.] 83.1%–94.2%; 1060/1179 patients; I2 = 82%). The estimated rate of non-shockable presenting rhythms was 89% (95% P.I. 82.8%–93.1%; 1022/1205 patients; I2 = 85%), and the estimated rate of ROSC was 32.9% (95% P.I. 26%–40.6%; 365/1205 patients; I2 = 82%). The estimated overall rate of survival with favorable neurological status at 30 days was 6.3% (95% P.I. 4%–9.7%; 50/851 patients; I2 = 48%). Sensitivity analysis showed that COVID-19 patients had higher risk of death after IHCA than non COVID-19 patients (OR 2.34; 95% C.I. 1.37–3.99; number of studies = 3; 1215 patients). Conclusions: Although one of three COVID-19 patients undergoing IHCA may achieve ROSC, almost 90% may not survive at 30 days or to hospital discharge.
