A BAC level of 50\u2005mg\/dL was defined as the cut-off value.

Alcohol use was associated with a shorter length of hospital stay (8.6 vs 11.4\u2005days, p=0.000) in patients with an ISS of &lt;16. Of 496 patients with positive BAC who underwent brain CT, 164 (33.1%) showed positive findings on CT scan. In contrast, of 891 patients with negative BAC who underwent brain CT, 389 (43.7%) had positive findings on CT scan. The lower percentage of positive CT scan findings in patients with positive BAC was particularly evident in patients with an ISS &lt;16 (18.0% vs 28.8%, p=0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Patients who consumed alcohol tended to have a low GCS score and injuries that were less severe.
