The Outcome of Severe Traumatic Brain Injury in Latin America

Abstract:

Background: Traumatic brain injury (TBI) disproportionately affects lower- and middle-income countries (LMIC). The factors influencing outcomes in LMIC have not been examined as rigorously as in higher-income countries. Methods: This study was conducted to examine clinical and demographic factors influencing TBI outcomes in Latin American LMIC. Data were prospectively collected during a randomized trial of intracranial pressure monitoring in severe TBI and a companion observational study. Participants were aged ≥13 years and admitted to study hospitals with Glasgow Coma Scale score ≤8. The primary outcome was Glasgow Outcome Scale, Extended (GOS-E) score at 6 months. Pbkp_redictors were analyzed using a multivariable proportional odds model created by forward stepwise selection. Results: A total of 550 patients were identified. Six-month outcomes were available for 88%, of whom 37% had died and 44% had achieved a GOS-E score of 5–8. In multivariable proportional odds modeling, higher Glasgow Coma Scale motor score (odds ratio [OR], 1.41 per point; 95% confidence interval [CI], 1.23–1.61) and epidural hematoma (OR, 1.83; 95% CI, 1.17–2.86) were significant pbkp_redictors of higher GOS-E score, whereas advanced age (OR, 0.65 per 10 years; 95% CI, 0.57–0.73) and cisternal effacement (P < 0.001) were associated with lower GOS-E score. Study site (P < 0.001) and race (P = 0.004) significantly pbkp_redicted outcome, outweighing clinical variables such as hypotension and pupillary examination. Conclusions: Mortality from severe TBI is high in Latin American LMIC, although the rate of favorable recovery is similar to that of high-income countries. Demographic factors such as race and study site played an outsized role in pbkp_redicting outcome; further research is required to understand these associations.
