Early initiation, good cardiopulmonary resuscitation (CPR) quality, and the use of an automated external defibrillator (AED) significantly improved survival and long-term outcomes in survivors of OHCA. In China, the survival rate of OHCA is less than 1%. Worldwide, survival after OHCA remains poor. In China, there are more than 230 million people with cardiovascular disease, and 550,000 individuals experience cardiac arrest every year. Out-of-hospital cardiac arrest (OHCA) is a major public health challenge, with an average global incidence among adults of 55 OHCAs per 100,000 person-years. A higher survival rate post-OHCA is more likely among patients who receive bystander CPR and who live in Western countries.

The global survival rate of OHCA patients who received CPR has increased in the past 40 years. The Egger’s test did not indicate evidence of publication bias for the outcomes of OHCA patients who underwent CPR. 13.3% in 2010–2019) rates of OHCA patients who underwent CPR significantly increased throughout the study period. The survival to discharge (8.6% in 1976–1999 vs. Subgroup analysis showed that survival to hospital discharge was more likely among OHCA patients whose cardiac arrest was witnessed by a bystander or emergency medical services (EMS) (10.5% 95% CI 9.2–11.7%), who received bystander CPR (11.3%, 95% CI 9.3–13.2%), and who were living in Europe and North America (Europe 11.7% 95% CI 10.5–13.0% North America: 7.7% 95% CI 6.9–8.6%). The pooled incidence of return of spontaneous circulation (ROSC) was 29.7% (95% CI 27.6–31.7%), the rate of survival to hospital admission was 22.0% (95% CI 20.7–23.4%), the rate of survival to hospital discharge was 8.8% (95% CI 8.2–9.4%), the pooled 1-month survival rate was 10.7% (95% CI 9.1–13.3%), and the 1-year survival rate was 7.7% (95% CI 5.8–9.5%).

ResultsĪ total of 141 eligible studies were included in this meta-analysis.

The overall incidence and outcome of OHCA were assessed using a random-effects meta-analysis. We systematically searched the PubMed, Embase, and Web of Science databases, and the references of retrieved articles were manually reviewed to identify studies reporting the outcome of OHCA patients who received CPR. To quantitatively summarize the available epidemiological evidence on the survival rate of out-of-hospital cardiac arrest (OHCA) patients who received cardiopulmonary resuscitation (CPR).
