We aimed to derive a prognostic model for predicting incomplete recovery at 1-month in emergency department (ED) patients with mTBI and a presenting Glasgow Coma Scale (GCS) score of 15 who were enrolled in the HeadSMART (Head Injury Serum Markers for Assessing Response to Trauma) study. The derivation cohort included 355 participants with complete baseline (day-of-injury) and follow-up data. The primary outcome measure was the Glasgow Outcome Scale Extended (GOSE) at 1-month and incomplete recovery was defined as a GOSE &lt;8. At 1-month post-injury, incomplete recovery was present in 58% (\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    \u2009=\u2009205) of participants. The final multi-variable logistic regression model included six variables: age in years (odds ratio [OR]\u2009=\u20090.98; 95% confidence interval [CI]: 0.97-1.00), positive head CT (OR\u2009=\u20094.42; 95% CI: 2.21-9.33), history of depression (OR\u2009=\u20092.59; 95% CI: 1.47-4.69), and self-report of moderate or severe headache (OR\u2009=\u20092.49; 95% CI: 1.49-4.18), difficulty concentrating (OR\u2009=\u20093.17; 95% CI: 1.53-7.04), and photophobia (OR\u2009=\u20094.17; 95% CI: 2.08-8.92) on the day-of-injury. The model was validated internally using bootstrap resampling (1000 resamples), which revealed a mean over-optimism value of 0.01 and an optimism-corrected area under the curve (AUC) of 0.79 (95% CI: 0.75-0.85). A prognostic model for predicting incomplete recovery among ED patients with mTBI and a presenting GCS of 15 using easily obtainable clinical and demographic variables has acceptable discriminative accuracy. External validation of this model is warranted.\n                  <\/jats:p>","DOI":"10.1089\/neu.2021.0137","type":"journal-article","created":{"date-parts":[[2021,5,7]],"date-time":"2021-05-07T01:30:47Z","timestamp":1620351047000},"page":"2714-2722","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":28,"title":["A Prognostic Model for Predicting One-Month Outcomes among Emergency Department Patients with Mild Traumatic Brain Injury and a Presenting Glasgow Coma Scale of Fifteen"],"prefix":"10.1177","volume":"38","author":[{"given":"Hayley","family":"Falk","sequence":"first","affiliation":[{"name":"Department of Computational Medicine and Bioinformatics, University of Michigan, Ann Arbor, Michigan, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathleen T.","family":"Bechtold","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Johns Hopkins University, Baltimore, Maryland, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew E.","family":"Peters","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Johns Hopkins University, Baltimore, Maryland, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Durga","family":"Roy","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Johns Hopkins University, Baltimore, Maryland, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vani","family":"Rao","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Johns Hopkins University, Baltimore, Maryland, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariel","family":"Lavieri","sequence":"additional","affiliation":[{"name":"Department of Industrial and Operations Engineering, University of Michigan, Ann Arbor, Michigan, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haris","family":"Sair","sequence":"additional","affiliation":[{"name":"Department of Radiology and Radiological Science, Johns Hopkins University, Baltimore, Maryland, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy E.","family":"Van Meter","sequence":"additional","affiliation":[{"name":"BRAINBox Solutions, Inc., Richmond, Virgina, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederick","family":"Korley","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, University of Michigan, Ann Arbor, Michigan, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,9,14]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/HTR.0000000000000187"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/HTR.0000000000000260"},{"key":"e_1_3_4_4_2","first-page":"81","article-title":"Assessment of coma and impaired consciousness","author":"Teasdale G.","year":"1974","unstructured":"Teasdale G., and Jennett B.
