Key result
Bystander cardiopulmonary resuscitation was associated with 23% lower 1-year mortality compared with first responders among elderly cardiac arrest survivors (HR 0.77; 95% CI 0.58-1.02).

Hazard Ratio: 0.77 (95% CI 0.58–1.02)
Elderly survivors of out-of-hospital cardiac arrest face high 1-year mortality (31.8%) and readmission rates (56.6%), with outcomes significantly influenced by functional status, neurological disability, and bystander CPR.

Elderly OHCA survivors incur high 1-year mortality and readmissions; leaves open targeted post-discharge strategies for prospective evaluation.
Chan et al. (2016) conducted a cohort in Out-of-hospital cardiac arrest (n=1,127). Bystander delivery of cardiopulmonary resuscitation vs. First responders was evaluated on 1-year mortality (HR 0.77, 95% CI 0.58-1.02). Bystander cardiopulmonary resuscitation was associated with 23% lower 1-year mortality compared with first responders among elderly cardiac arrest survivors (HR 0.77; 95% CI 0.58-1.02).
