A Population-Based Sex-Stratified Study to Understand How Health Status Preceding Traumatic Brain Injury Affects Direct Medical Cost

Research Objectives To understand how pre-injury health status present five-years preceding traumatic brain injury (TBI) affects direct medical cost two years post-injury. Design Retrospective cohort study. Setting Publicly funded healthcare system in Ontario, Canada. Participants Patients age 19 or older the emergency department (ED) acute care for a TBI between April 1, 2007 and March 31, 2014 (N=55,669). Interventions N/A. Main Outcome Measures Direct costs within of discharge. Results who received ED (81.9% total sample) incurred median $2,492/male patient (average $12,342/patient) $3,508/female $12,372/patient) injury; 37 factors were significantly associated with increased costs. first their (18.1%) $25,081/male $63,060/patient) $30,277/female $65,285/patient) 21 Among more prevalent factors, those by at least 50% included mental disorders, substance abuse, disorders conditions frequently observed among elderly, cardiovascular stroke emergencies involving brain, metabolic abdominal symptoms, symptoms abdomen pelvis, genitourinary prostate, pulmonary other emergencies. Conclusions post-TBI differed patients without adverse pre-existing status. Interdisciplinary teams to promote early identification appropriate management integration these across continuum may be opportunities reduce Author(s) Disclosures None.
