Thirty-day survival after out-of-hospital cardiac arrest in Sweden more than doubled between 1992 and 2011, likely driven by improvements across all links in the chain of survival.
Strömsöe et al. (2014) conducted an observational in Out-of-hospital cardiac arrest (n=59,926). Improvements in the chain of survival (2011 vs 1992) vs. Historical baseline (1992) was evaluated on 30-day survival (p=<0.0001). Thirty-day survival after out-of-hospital cardiac arrest in Sweden increased from 4.8% in 1992 to 10.7% in 2011 (P<0.0001), alongside improvements in all links of the chain of survival.
