Physicians didn’t improve outcome from nontraumatic cardiac arrest

A Norwegian study retrospectively compared outcomes from non-traumatic cardiac arrest between ambulances staffed by physicians (PMA) and non-physician ambulances (non-PMA). There were no differences in any of the clinical outcome measures used in this study of 977 patients, in which 13% (PMA) and 11% (non-PMA) survived to hospital discharge.
