Calculated Radiation Exposure for Trauma Patients is Lower when using the New Injury Severity Score Versus the Injury Severity Score to Calculate Injury Severity

We studied radiation exposure (RE) in trauma patients [1]. To adjust for injury severity the New Injury Severity Score (NISS) or the Injury Severity Score (ISS) can be used to group patients. We sought to determine whether there is a difference in the calculated RE per group when the patients are grouped using either the NISS or ISS.
