The impact of the SARS-CoV-2 pandemic on in-hospital cardiac arrest: A systematic review and meta-analysis
Abstract
Background: There is an emerging concern regarding the indirect effect the Covid-19 pandemic has had on the care provided to patients. New resuscitation guidance including the donning of Personal Protective Equipment before commencing resuscitation efforts, the avoidance of bag-mask ventilation, limiting the number of responders and stopping resuscitation efforts earlier could have led to worse outcomes following in-hospital cardiac arrest (IHCA) when compared to the non-pandemic period. The primary objective was to understand the impact of the pandemic on patient outcomes following IHCA by comparing the pandemic and non-pandemic periods. Methods: Our systematic search was conducted on the 13th of September 2022 in three databases: Medline, Embase and Central. Randomised or non-randomised clinical trials and observational studies were included. The search was repeated on 31st December 2023 and there were no new studies appropriate for inclusion which had been published in the interim. The patient population consisted of adult patients who suffered IHCA due to any cause. The primary outcome was survival to hospital discharge (SHD). The secondary outcomes were return of spontaneous circulation (ROSC) and length of resuscitation. Results: We identified 1873 studies, 9 were included in our qualitative analysis. SHD was reported in 8 studies with no difference between the two periods (OR 0.69; 95% CI 0.47–1.03) along with resuscitation (MD: 0.74; 95% CI: −0.67 to 2.14; p = 0.153. ROSC was included in all studies and showed significant difference between the two periods (OR 0.75; 95% 0.60–0.95) Conclusion: Although SHD was similar between the two periods, ROSC was significantly lower during the pandemic with longer resuscitation times highlighting a substantial impact of the pandemic on patient outcomes.
