“…A correlation between COVID-19 cases and OHCA incidence has also been described by a previous study of our group carried out in the south part of the Lombardy Region [10] and by a study from London [22], both focused on the first 60 days of the pandemic. On the other hand, another study from Switzerland [30] didn't highlighted an excess of OHCA in 2020 as compared to 2019. This was found also in those Cantons with a high incidence of COVID-19; however, albeit high for Switzerland, the incidence of COVID-19 in the Swiss Cantons was less than half of our high-incidence provinces, resembling the scene of our low-incidence provinces.…”

Background The relationship between COVID-19 and out-of-hospital cardiac arrests (OHCAs) has been shown during different phases of the first pandemic wave, but little is known about how to predict where cardiac arrests will increase in case of a third peak. Aim To seek for a correlation between the OHCAs and COVID-19 daily incidence both during the two pandemic waves at a provincial level. Methods We considered all the OHCAs occurred in the provinces of Pavia, Lodi, Cremona, Mantua and Varese, in Lombardy Region (Italy), from 21/02/2020 to 31/12/2020. We divided the study period into period 1, the first 157 days after the outbreak and including the first pandemic wave and period 2, the second 158 days including the second pandemic wave. We calculated the cumulative and daily incidence of OHCA and COVID-19 for the whole territory and for each province for both periods. Results A significant correlation between the daily incidence of COVID-19 and the daily incidence of OHCAs was observed both during the first and the second pandemic period in the whole territory (R = 0.4, p<0.001 for period 1 and 2) and only in those provinces with higher COVID-19 cumulative incidence (period 1: Cremona R = 0.3, p = 0.001; Lodi R = 0.4, p<0.001; Pavia R = 0.3; p = 0.01; period 2: Varese R = 0.4, p<0.001). Conclusions Our results suggest that strictly monitoring the pandemic trend may help in predict which territories will be more likely to experience an OHCAs’ increase. That may also serve as a guide to re-allocate properly health resources in case of further pandemic waves.

“…A flow diagram showing stages of database search and study selection is shown in Figure 1. Twenty-seven studies reported OHCA outcomes in pre-vs. intra-COVID-19 periods [23,24,[26][27][28][29]31,33,35,[37][38][39][40][41][42][44][45][46][47][48][49][50][51][52][53], and OHCA outcomes in SARS-CoV-2-positive vs. -negative patients were reported in seven trials [25,30,32,34,36,43,51]. Characteristics of the individual studies are presented in Tables S1 and S2.…”

“…The Cochrane risk of bias of the included studies is shown in Figures S1 and S2. The overall risk of bias was judged as low in twenty-nine studies [23][24][25][26][27][28][29][30][31][32][34][35][36][37][38][39][40][41][42][43][44][45][46][48][49][50][51][52][53], and reviewers indicate some concerns on the other two [33,47].…”

Cardiopulmonary resuscitation in patients with out-of-hospital cardiac arrest (OHCA) is associated with poor prognosis. Because the COVID-19 pandemic may have impacted mortality and morbidity, both on an individual level and the health care system as a whole, our purpose was to determine rates of OHCA survival since the onset of the SARS-CoV2 pandemic. We conducted a systematic review and meta-analysis to evaluate the influence of COVID-19 on OHCA survival outcomes according to the PRISMA guidelines. We searched the literature using PubMed, Scopus, Web of Science and Cochrane Central Register for Controlled Trials databases from inception to September 2021 and identified 1775 potentially relevant studies, of which thirty-one articles totaling 88,188 patients were included in this meta-analysis. Prehospital return of spontaneous circulation (ROSC) in pre-COVID-19 and COVID-19 periods was 12.3% vs. 8.9%, respectively (OR = 1.40; 95%CI: 1.06–1.87; p < 0.001). Survival to hospital discharge in pre- vs. intra-COVID-19 periods was 11.5% vs. 8.2% (OR = 1.57; 95%CI: 1.37–1.79; p < 0.001). A similar dependency was observed in the case of survival to hospital discharge with the Cerebral Performance Category (CPC) 1–2 (6.7% vs. 4.0%; OR = 1.71; 95%CI: 1.35–2.15; p < 0.001), as well as in the 30-day survival rate (9.2% vs. 6.4%; OR = 1.63; 95%CI: 1.13–2.36; p = 0.009). In conclusion, prognosis of OHCA is usually poor and even worse during COVID-19.

“…Several previous studies have compared the general characteristics, such as incidence and prognosis of OHCA patients between the pre-COVID-19 and COVID-19 period. In the COVID-19 periods, OHCA mortality increased with a high incidence of infection in Switzerland, and there was a transient two-fold increase in the incidence of OHCA with decreased survival in France [16] , [17] . We focused on examining changes in the transport process in patients with OHCA using data from EMS records.…”
