0660 Identifying Patients at Risk of Acute Sleep Disturbances Within the Immediate Aftermath of Trauma

Abstract Introduction Acute sleep disturbances are a common, modifiable consequence of trauma that, if left untreated, increase risk PTSD by nearly two-fold. This suggests acute after an important contributor to the etiology that could be targeted early prevent disorder. Yet, effective strategies cannot currently implemented because we identify who is most at trauma, thus obstructing ability high-risk groups in need intervention. study will test reactivity – trait predisposition experience stress as predictor posttraumatic within one month following exposure. Methods We recruited patients admitted Henry Ford Hospital’s intensive care unit Detroit for traumatic injury (e.g., gunshot wound) (N = 88, M age 39.53, SD 14.31). While hospitalized, reported their pre-trauma (Ford Insomnia Response Stress Test; FIRST) and insomnia symptoms from past two weeks (Insomnia Severity Index; ISI). Patients then completed ISI again later (n 48). tested high (FIRST > 21) prospective clinically significant (ISI 10). Results were mostly black men (67%), half annual income < $20,000 (47.7%). Motor vehicle collisions common precipitated patients’ hospital admission (42%), followed assaults with weapon (30.7%). adjusting disturbance, predicted increased odds (b 2.08, SE .98, p .033, OR 8.01, CI 1.19 54.15). Conclusion Individuals susceptibility trauma. The 9-item FIRST brief useful indicator offers providers predict onset which novel targets might enable identification potentially vulnerable individuals develop PTSD, toward whom sleep-focused preventive efforts can targeted.
