Association Between Charlson Comorbidity Index Items and Outcomes in Patients With Blunt Trauma Using a Nationwide Trauma Registry Database in Japan

CONCLUSION: Comorbidities that can affect the prognosis of blunt trauma were identified from the items in the original CCI. It is beneficial for emergency medical personnel to know about pre-existing comorbidities associated with the prognosis of blunt trauma cases when selecting a transport facility before arrival at the hospital, and the condition of trauma cases with pre-existing or dysfunctional major organs, such as the liver, kidneys, heart, and lungs, should not be underestimated.
