Out-of-hospital cardiac arrests in nursing homes and primary care facilities in Pirkanmaa, Finland.

The do-not-attempt-resuscitation orders were often unavailable during a cardiopulmonary resuscitation attempt. Although resuscitation attempts were futile for patients in nursing homes, some patients in primary care facilities demonstrated a favourable outcome after cardiac arrest. Emergency Medical Services seem to be able to recognise potential survivors and focus resources on their treatment.
