Prognostic Value of Serially Estimated Serum Procalcitonin Levels in Traumatic Brain Injury Patients With or Without Extra Cranial Injury on Early In-hospital Mortality: A Longitudinal Observational Study

OBJECT Well-designed studies linking intracranial pressure (ICP) monitoring with improved outcomes among children with severe traumatic brain injury (TBI) are lacking. The main objective of this study was to examine the relationship between ICP monitoring in children and in-hospital mortality following severe TBI. METHODS An observational study was conducted using data derived from 153 adult or mixed (adult and pediatric) trauma centers participating in the American College of Surgeons (ACS) Trauma Quality Improvement Program (TQIP) and 29 pediatric trauma centers participating in the pediatric pilot TQIP between 2010 and 2012. Random-intercept multilevel modeling was used to examine the association between ICP monitoring and in-hospital mortality among children with severe TBI ≤16 years of age after adjusting for important confounders. This association was evaluated at the patient level and at the hospital level. In a sensitivity analysis, this association was reexamined in a propensity-matched cohort. RESULTS A total of 1705 children with severe TBI were included in the study cohort. The overall in-hospital mortality was 14.3% of patients (n = 243), whereas the mortality of the 273 patients (16%) who underwent invasive ICP monitoring was 11% (n = 30). After adjusting for patient- and hospital-level characteristics, ICP monitoring was associated with lower in-hospital mortality (adjusted OR 0.50; 95% CI 0.30–0.85; p = 0.01). It is possible that patients who were managed with ICP monitoring were selected because of an anticipated favorable or unfavorable outcome. To further address this potential selection bias, the analysis was repeated with the hospital-specific rate of ICP monitoring use as the exposure. The adjusted OR for death of children treated at high ICP–use hospitals was 0.49 compared with those treated at low ICP-use hospitals (95% CI 0.31–0.78; p = 0.003). Variations in ICP monitoring use accounted for 15.9% of the interhospital variation in mortality among children with severe TBI. Similar results were obtained after analyzing the data using propensity score-matching methods. CONCLUSIONS In this observational study, ICP monitoring use was associated with lower hospital mortality at both the patient and hospital levels. However, the contribution of variable ICP monitoring rates to interhospital variation in pediatric TBI mortality was modest.

Abstract Objectives We aimed to develop a prognostic model for the prediction of in-hospital mortality in patients with traumatic brain injury (TBI) admitted to the neurosurgery intensive care unit (ICU) of our institute. Materials and Methods The clinical and computed tomography scan data of consecutive patients admitted after a diagnosis TBI in ICU were reviewed. Construction of the model was done by using all the variables of Corticosteroid Randomization after Significant Head Injury and International Mission on Prognosis and Analysis of Clinical Trials in TBI models. The endpoint was in-hospital mortality. Results A total of 243 patients with TBI were admitted to ICU during the study period. The in-hospital mortality was 15.3%. On multivariate analysis, the Glasgow coma scale (GCS) at admission, hypoxia, hypotension, and obliteration of the third ventricle/basal cisterns were significantly associated with mortality. Patients with hypoxia had eight times, with hypotensions 22 times, and with obliteration of the third ventricle/basal cisterns three times more chance of death. The TBI score was developed as a sum of individual points assigned as follows: GCS score 3 to 4 (+2 points), 5 to 12 (+1), hypoxia (+1), hypotension (+1), and obliteration third ventricle/basal cistern (+1). The mortality was 0% for a score of “0” and 85% for a score of “4.” Conclusion The outcome of patients treated in ICU was based on common admission variables. A simple clinical grading score allows risk stratification of patients with TBI admitted in ICU.
