The Scandinavian Guidelines for Initial Management of Minimal, Mild, and Moderate Head Injuries in Adults were the first clinical decision rules in the field with an incorporated biomarker, the S100 astroglial calcium-binding protein B (S100B), which is used in the Mild (Low Risk) group defined by the guidelines. Our aim was to evaluate the performance of the guidelines when S100B was substituted with GFAP. The sample (<i>N</i> = 296) was recruited from the Tampere University Hospital's emergency department between November 2015 and November 2016, and there were 49 patients with available GFAP results who were stratified in the Mild (Low Risk) group (thus patients undergoing biomarker triaging). A previously reported cutoff of plasma GFAP ≥140 pg/mL was used. Within the Mild (Low Risk) group (<i>n</i> = 49), GFAP sensitivity (with 95% confidence intervals in parentheses) for detecting traumatic CT abnormalities was 1.0 (0.40-1.00), specificity 0.34 (0.19-0.53), the negative predictive value (NPV) 1.0 (0.68-1.00), and the positive predictive value (PPV) 0.16 (0.05-0.37). The sensitivity and specificity of the modified guidelines with GFAP, when applied to all imaged patients (<i>n</i> = 197) in the whole sample, were 0.94 (0.77-0.99) and 0.20 (0.15-0.28), respectively. NPV was 0.94 (0.80-0.99) and PPV 0.18 (0.13-0.25). In the Mild (Low Risk) group, none of the patients with GFAP results below 140 pg/mL had traumatic abnormalities on their head CT. These findings were derived from a small patient subgroup.

Given that these neuropsychiatric morbidities are frequently observed in SCI patients, the effects of pre-injury AUD on risk of depression, anxiety, or chronic pain were analyzed using an insurance claim database. Of 10,591 traumatic SCI patients, 507 had AUD-associated claims in a 12-month period before injury. Those AUD-positive SCI patients showed distinct demographic characteristics, including greater representation of men, younger age, more comorbidities, lower coverage by commercial insurance, and more cervical-level injuries. The AUD group also showed elevated pre-injury comorbidity of depression, anxiety, and chronic pain. However, multi-regression analysis revealed an increased odds ratio (OR) of <i>de novo</i> diagnosis of post-SCI depression in AUD patients 6 months (1.671; 95% confidence interval [CI]: 1.124, 2.483) and 1 year post-injury (1.511; 95% CI: 1.071, 2.131).
