Recalibrating the Glasgow Coma Score as an Age-Adjusted Risk Metric for Neurosurgical Intervention. J Surg Res 2021; 268:696-704. [PMID: 34487962 DOI: 10.1016/j.jss.2021.08.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 07/15/2021] [Accepted: 08/04/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND The Glasgow Coma Scale (GCS) score is the most frequently used neurologic assessment in traumatic brain injury (TBI). The risk for neurosurgical intervention based on GCS is heavily modified by age. The objective is to create a recalibrated Glasgow Coma Scale (GCS) score that accounts for an interaction by age and determine the predictive performance of the recalibrated GCS (rGCS) compared to the standard GCS for predicting neurosurgical intervention. METHODS This retrospective cohort study utilized the National Trauma Data Bank and included all patients admitted from 2010-2015 with TBI (ICD9 diagnosis code 850-854.19). The study population was divided into 2 subsets: a model development dataset (75% of patients) and a model validation dataset (remaining 25%). In the development dataset, logistic regression models were used to calculate conditional probabilities of having a neurosurgical intervention for each combination of age and GCS score, to develop a point-based risk score termed the rGCS. Model performance was examined in the validation dataset using area under the receiver operating characteristic (AUROC) curves and calibration plots. RESULTS There were 472,824 patients with TBI. The rGCS ranged from 1-15, where rGCS 15 denotes the baseline risk for neurosurgical intervention (4.4%) and rGCS 1 represents the greatest risk (62.6%). In the validation dataset there was a statistically significant improvement in predictive performance for neurosurgical intervention for the rGCS compared to the standard GCS (AUROC: 0.71 versus 0.67, difference, -0.04, P<0.001), overall and by trauma level designation. The rGCS was better calibrated than the standard GCS score. CONCLUSIONS The relationship between GCS score and neurosurgical intervention is significantly modified by age. A revision to the GCS that incorporates age, the rGCS, provides risk of neurosurgical intervention that has better predictive performance than the standard ED GCS score.

Functional outcome, in-hospital healthcare consumption and in-hospital costs for hospitalised traumatic brain injury patients: a Dutch prospective multicentre study.

Abstract
BACKGROUND The high occurrence and acute and chronic sequelae of traumatic brain injury (TBI) cause major healthcare and socioeconomic challenges. This study aimed to describe outcome, in-hospital healthcare consumption and in-hospital costs of patients with TBI. METHODS We used data from hospitalised TBI patients that were included in the prospective observational CENTER-TBI study in three Dutch Level I Trauma Centres from 2015 to 2017. Clinical data was completed with data on in-hospital healthcare consumption and costs. TBI severity was classified using the Glasgow Coma Score (GCS). Patient outcome was measured by in-hospital mortality and Glasgow Outcome Score-Extended (GOSE) at 6 months. In-hospital costs were calculated following the Dutch guidelines for cost calculation. RESULTS A total of 486 TBI patients were included. Mean age was 56.1 ± 22.4 years and mean GCS was 12.7 ± 3.8. Six-month mortality (4.2%-66.7%), unfavourable outcome (GOSE ≤ 4) (14.6%-80.4%) and full recovery (GOSE = 8) (32.5%-5.9%) rates varied from patients with mild TBI (GCS13-15) to very severe TBI (GCS3-5). Length of stay (8 ± 13 days) and in-hospital costs (€11,920) were substantial and increased with higher TBI severity, presence of intracranial abnormalities, extracranial injury and surgical intervention. Costs were primarily driven by admission (66%) and surgery (13%). CONCLUSION In-hospital mortality and unfavourable outcome rates were rather high, but many patients also achieved full recovery. Hospitalised TBI patients show substantial in-hospital healthcare consumption and costs, even in patients with mild TBI. Because these costs are likely to be an underestimation of the actual total costs, more research is required to investigate the actual costs-effectiveness of TBI care.

Abstract
PURPOSE OF REVIEW Traumatic brain injury (TBI) remains an unfortunately common disease with potentially devastating consequences for patients and their families. However, it is important to remember that it is a spectrum of disease and thus, a one 'treatment fits all' approach is not appropriate to achieve optimal outcomes. This review aims to inform readers about recent updates in prehospital and neurocritical care management of patients with TBI. RECENT FINDINGS Prehospital care teams which include a physician may reduce mortality. The commonly held value of SBP more than 90 in TBI is now being challenged. There is increasing evidence that patients do better if managed in specialized neurocritical care or trauma ICU. Repeating computed tomography brain 12 h after initial scan may be of benefit. Elderly patients with TBI appear not to want an operation if it might leave them cognitively impaired. SUMMARY Prehospital and neuro ICU management of TBI patients can significantly improve patient outcome. However, it is important to also consider whether these patients would actually want to be treated particularly in the elderly population.

Abstract
Objective Despite recent advances in medicine, no significant improvement has been achieved in therapeutic outcomes for severe traumatic brain injury (TBI). In the treatment of severe multiple traumas, accurate judgment and prompt action corresponding to rapid pathophysiological changes are required. Therefore, we developed the “All-in-One” therapeutic strategy for severe TBI. In this report, we present the therapeutic concept and discuss its efficacy and limitations. Methods From April 2007 to December 2015, 439 patients diagnosed as having traumatic intracranial injuries were treated at our institution. Among them, 158 patients were treated surgically. The “All-in-One” therapeutic strategy was adopted to enforce all selectable treatments for these patients at the initial stages. The outline of this strategy is as follows: first, prompt trepanation surgery in the emergency room (ER); second, extensive decompression craniotomy (DC) in the operating room (OR); and finally, combined mild hypothermia and moderate barbiturate (H-B) therapy for 3 to 5 days. We performed these approaches on a regular basis rather than stepwise rule. If necessary, internal ecompression surgery and external ventricular drainage were performed in cases in which intracranial pressure could not be controlled. Results Trepanation surgery in the ER was performed in 97 cases; among these cases, 46 had hematoma removal surgery and also underwent DC in the OR. Craniotomy was not enforced unless the consciousness level and pupil findings did not improve after previous treatments. H-B therapy was administered in 56 cases. Internal decompression surgery, including evacuation of traumatic intracerebral hematoma, was additionally performed in 12 cases. Three months after injury, the Glasgow Outcome Scale (GOS) score yielded the following results: good recovery in 25 cases (16%), mild disability in 28 (18%), severe disability in 33 (21%), persistent vegetative state in 9 (6%), and death in 63 (40%). Furthermore, 27 (36%) of the 76 most severe patients who had an abnormal response of bilateral eye pupils were life-saving. Because many cases of a GOS score of ≤5 are included in this study, this result must be satisfactory. Conclusion This therapeutic strategy without any lose in the appropriate treatment timing can improve the outcomes of the most severe TBI cases. We think that the breakthrough in the treatment of severe TBI will depend on the shift in the treatment policy.

Abstract
To date, a large amount of retrospectively collected data about treatment of neurosurgical pathology have been accumulated. Modern methods of medical statistics are necessary for correct interpretation of the data. The article purpose is to demonstrate application of one of the modern methods, Propensity Score Matching (PSM), in neurosurgery. The use of PSM avoids misinterpretation of retrospectively collected data and obviates errors in planning further prospective studies. For the past 10 years, the number of published international PSM-based studies has increased more than 10-fold, with the number of articles by Russian authors accounting for less than 0.2%. In line with the tendencies of international studies, application of PSM in analysis of retrospectively collected data will enable testing of a number of hypotheses and correct planning of prospective randomized studies.

Abstract
Coma has many causes but there are a few urgent ones in clinical practice. Management must start with establishing the cause and an attempt to reverse or attenuate some of the damage. This may include early neurosurgical intervention, efforts to reduce brain tissue shift and raised intracranial pressure, correction of markedly abnormal laboratory abnormalities, and administration of available antidotes. Supporting the patient's vital signs, susceptible to major fluctuations in a changing situation, remains the most crucial aspect of management. Management of the comatose patient is in an intensive care unit and neurointensivists are very often involved. This chapter summarizes the principles of caring for the comatose patient and everything a neurologist would need to know. The basic principles of neurologic assessment of the comatose patient have not changed, but better organization can be achieved by grouping comatose patients according to specific circumstances and findings on neuroimaging. Ongoing supportive care involves especially aggressive prevention of medical complications associated with mechanical ventilation and prolonged immobility. Waiting for recovery-and many do- is often all that is left. Neurorehabilitation of the comatose patient is underdeveloped and may not be effective. There are, as of yet, few proven options for neurostimulation in comatose patients.
