“The upward trend of out-of-hospital survival came to an end for several reasons. First, the ambulances aren't managing to arrive in time for the patients; the delays in getting to them have constantly increased. Second, the proportion of patients who are relatively easy to resuscitate — that is, those whose heart stops because of acute or chronic coronary artery disease — has fallen dramatically in the past few decades.”
Clinicians should note stalled OHCA survival and static neurological outcomes; leaves open research into EMS delays and neuroprotection.
Jerkeman et al. (2022) conducted an observational in Cardiac arrest (out-of-hospital and in-hospital) (n=136,328). Later time period (2017-2020) vs. Earlier time period (1990-1993 for OHCA; 2004-2007 for IHCA) was evaluated on Survival (OHCA) (OR 2.17, 95% CI 1.93-2.43). Survival after out-of-hospital cardiac arrest increased significantly from 1990-1993 to 2017-2020 (OR 2.17; 95% CI 1.93-2.43), though improvements plateaued in the final decade.
