Warning over increasing cardiac deaths outside of hospitals

A retrospective study of out-of-hospital cardiac arrests, taken from NSW metropolitan ambulance data in 2004–05 and 2009–2010, showed survival at 90 days declined from 12.3% in 2004–05 to 10.2% in 2009–10.

However, the age-standardised incidence of out-of-hospital cardiac arrest declined over the same period from 52.6 to 48.4 events per 100,000 people.

Study author Associate Professor Paul Middleton, chair of the Australian Resuscitation Council NSW, said the findings were extremely disappointing.
