Cardiopulmonary Resuscitation Outcomes of Patients with COVID-19; a One-Year Survey.
Introduction
Assessing cardiopulmonary resuscitation (CPR) outcomes of patients with COVID-19 and employing effective strategies for their improvement are essential. This study is designed in this regard.


Methods
This cross-sectional study was conducted between January 20, 2020 and January 20, 2021 in the emergency departments of two hospitals in Hamadan and Kermanshah, Iran. Participants were 487 patients with confirmed COVID-19 and cardiac arrest (CA) who had undergone CPR during the study period. Data were collected using the available CPR documentation forms developed based on the Utstein Style and analyses were performed using Chi-square, Fisher's exact, and Mann-Whitney U tests and the logistic regression analysis.


Results
Participants' mean age was 69.31±14.73 years and most of them were male (61.8%) and suffered from at least one underlying disease (58.1%). The rate of total and in-hospital CA was 9.67% and 9.39%, respectively. The most prevalent first documented rhythm was asystole (67.9%) and the highest responsivity to CPR was for shockable rhythms. The rate of the return of spontaneous circulation (ROSC) was 9% and the rate of survival to hospital discharge was 2%. The significant predictors of CPR success were age (p = 0.035), epinephrine administration time interval (p = 0.00), CPR duration (p = 0.00), and First documented rhythm (p = 0.009).


Conclusion
The rate of in-hospital CA among studied COVID-19 cases was 9.39% with 9% ROSC and 2% survival to hospital discharge rates after CPR. Primary CPR success among patients with COVID-19 was poor, particularly among those with asystole and bradycardia. It seems that old age and improper doses of epinephrine can reduce CPR success.
