Masterson S, et al. - This retrospective cohort study of all cases of out-of-hospital cardiac arrest at international airports was performed to assess the crude incidence, patient, event characteristics and survival to hospital discharge/survival to 30 days (survival). Researchers noted that 32% of patients survived an out-of-hospital cardiac arrest in international airports, substantially more than in the general population. This analysis indicated similarity between airports within countries, but differences between countries.
