Prevalence of COVID-19 Among Patients Arriving in Pre-arrest/Cardiac Arrest, at a Tertiary Hospital's ED in the Eastern Province of Saudi Arabia During the COVID-19 Pandemic.

Abstract

Background: COVID-19 pandemic has thrown the healthcare systems into confusion worldwide, resulting in major modifications on the practice due to fear of exposure to this virus and its fatal consequences.

Objective: the study aimed to establish the prevalence of COVID-19 in cardiac arrest patients.

Methods: single-centered, Retrospective, observational cohort study that included all patients who presented to ED during the period of the pandemic from January 2021 to May 2022 and documented to have either IN-hospital cardiac arrest (IHCA), specifically within the ED, or OUT-hospital cardiac arrest (OHCA).

Results: This study analyzed 177 patients. Out of which, 30.5% of the patients were aged more than 70 years old. Those with associated comorbidities, the most frequently mentioned comorbidity was hypertension (40.7%). It was found that the prevalence of positive COVID-19 infection was significantly more common among non-Arab (p=0.019), patients with associated chronic kidney disease (p=0.019) and those who had an in-hospital cardiac arrest (p=0.010). No significant associations were observed between COVID-19 infection in terms of age, gender, nationality, associated comorbidities, symptoms, and trauma (all p>0.05).

Conclusion: This study showed the prevalence of COVID-19 among cardiac arrest patients within ED and outside the hospital in our study population. Based on the study's results, the major adjustments in practice were not absolutely needed. Also, this study could help in establishing a good mitigation strategy for at-risk patients.
