Survival from out-of-hospital cardiac arrest in New Zealand following the 2005 resuscitation guideline changes

Epidemiology of Sudden Cardiac Death: Global and Regional Perspectives

“…Sudden cardiac death figures in younger age groups vary from 1.1 to 8.7 per 100,000 [10][11][12], with corresponding estimates in adults over 18 years of age ranging from 102.0 to 147.8 per 100,000 [13,14]. A few studies [15][16][17] have suggested that the incidence of EMS-treated OOHCA is not dissimilar in New Zealand to Australia [15], and the AusROC Epistry demonstrated a similar incidence of all EMS-attended OOHCAs of 105.5 per 100,000 [3].…”

Part 8: Education, Implementation, and Teams

“…Seven studies showed that implementation of resuscitation guidelines improved ROSC (RR, 1.15; 95% CI, 1.11-1.20), [144][145][146][147][148][149][150] and 3 studies were neutral. 142,151,152 For the important outcome of CPR performance, we identified very-low-quality evidence (downgraded for imprecision, risk of bias, and indirectness) from 4 observational studies that implementation of resuscitation guidelines improved the hands-off ratio of emergency medical services CPR performance (mean 0.28 versus 0.42). 142,145,149,150 …”

RECOVER evidence and knowledge gap analysis on veterinary CPR. Part 4: Advanced life support

“…One study from 30 years ago (LOE 6, poor/neutral) evaluated a small group of people (n = 21) that experienced out‐of‐hospital cardiac arrest associated with asystole‐bradycardia and found no improvement in survival . Other studies included atropine as component of CPR (LOE 6, fair‐poor/neutral) and were largely unable to determine any specific beneficial or detrimental effect of atropine …”
