Arch Gerontol Geriatr 2024; 125:105488. [PMID: 38776698 DOI: 10.1016/j.archger.2024.105488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 05/13/2024] [Accepted: 05/16/2024] [Indexed: 05/25/2024]
Abstract
PURPOSE This study examined the research on older adults with a moderate to severe traumatic brain injury (TBI), with a focus on mortality and discharge disposition. METHOD Systematic searches were conducted in MEDLINE, CINAHL, EMBASE and PsycINFO for studies up to April 2022 in accordance with PRISMA guidelines. RESULTS 64 studies, published from 1992 to 2022, met the inclusion criteria. Mortality was higher for older adults ≥60 years old than for their younger counterparts; with a dramatic increase for those ≥80 yr, with rates as high as 93 %. Similar findings were reported regarding mortality in intensive care, surgical mortality, and mortality post-hospital discharge; with an 80 % rate at 1-year post-discharge. Up to 68.4 % of older adults were discharged home; when compared to younger adults, those ≥65 years were less likely to be discharged home (50-51 %), compared to those <64 years (77 %). Older adults were also more likely to be discharged to long-term care (up to 31.6 %), skilled nursing facilities (up to 46.1 %), inpatient rehabilitation (up to 26.9 %), and palliative or hospice care (up to 58 %). CONCLUSION Given their vulnerability, optimizing outcomes for older adults with moderate-severe TBI across the healthcare continuum is critical.

Abstract
Background Skull fracture can lead to significant morbidity and mortality, yet the development of effective predictive tools has remained a challenge. This study aimed to establish and validate a nomogram to evaluate the 28-day mortality risk among patients with skull fracture. Materials and methods Data extracted from the Medical Information Mart for Intensive Care (MIMIC) database were utilized as the training set, while data from the eICU Collaborative Research Database were employed as the external validation set. This nomogram was developed using univariate Cox regression, best subset regression (BSR), and the least absolute shrinkage and selection operator (LASSO) methods. Subsequently, backward stepwise multivariable Cox regression was employed to refine predictor selection. Variance inflation factor (VIF), akaike information criterion (AIC), area under the receiver operating characteristic curve (AUC), concordance index (C-index), calibration curve, and decision curve analysis (DCA) were used to assess the model's performance. Results A total of 1,527 adult patients with skull fracture were enrolled for this analysis. The predictive factors in the final nomogram included age, temperature, serum sodium, mechanical ventilation, vasoactive agent, mannitol, extradural hematoma, loss of consciousness and Glasgow Coma Scale score. The AUC of our nomogram was 0.857, and C-index value was 0.832. After external validation, the model maintained an AUC of 0.853 and a C-index of 0.829. Furthermore, it showed good calibration with a low Brier score of 0.091 in the training set and 0.093 in the external validation set. DCA in both sets revealed that our model was clinically useful. Conclusion A nomogram incorporating nine features was constructed, with a good ability in predicting 28-day mortality in patients with skull fracture.

Current Status of Intracranial Pressure Monitoring in Patients with Severe Traumatic Brain Injury in Korea : A Post Hoc Analysis of Korea Neurotrauma Databank Project with a Nationwide Survey. J Korean Neurosurg Soc 2023; 66:543-551. [PMID: 37016766 PMCID: PMC10483167 DOI: 10.3340/jkns.2023.0019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 03/21/2023] [Accepted: 03/29/2023] [Indexed: 04/06/2023] Open
Abstract
OBJECTIVE This study aimed to investigate the current status of intracranial pressure (ICP) monitoring in patients with severe traumatic brain injury (sTBI) in Korea and the association between ICP monitoring and prognosis. In addition, a survey was administered to Korean neurosurgeons to investigate the perception of ICP monitoring in patients with sTBI. METHODS This study used data from the second Korea Neurotrauma Databank. Among the enrolled patients with sTBI, the following available clinical data were analyzed in 912 patients : Glasgow coma scale score on admission, ICP monitoring, mortality, and extended Glasgow outcome scale score at 6 months. In addition, we administered a survey, entitled "current status and perception of ICP monitoring in Korean patients with sTBI" to 399 neurosurgeons who were interested in traumatic brain injury. RESULTS Among the 912 patients, 79 patients (8.7%) underwent ICP monitoring. The mortality and favorable outcome were compared between the groups with and without ICP monitoring, and no statistically significant results were found. Regarding the survey, there were 61 respondents. Among them, 70.4% of neurosurgeons responded negatively to performing ICP monitoring after craniectomy/craniotomy, while 96.7% of neurosurgeons responded negatively to performing ICP monitoring when craniectomy/ craniotomy was not conducted. The reasons why ICP monitoring was not performed were investigated, and most respondents answered that there were no actual guidelines or experiences with post-operative ICP monitoring for craniectomy/craniotomy. However, in cases wherein craniectomy/craniotomy was not performed, most respondents answered that ICP monitoring was not helpful, as other signs were comparatively more important. CONCLUSION The proportion of performing ICP monitoring in patients with sTBI was low in Korea. The outcome and mortality were compared between the patient groups with and without ICP monitoring, and no statistically significant differences were noted in prognosis between these groups. Further, the survey showed that ICP monitoring in patients with sTBI was somewhat negatively recognized in Korea.

Abstract
OBJECTIVE The purpose of this study was to compare therapeutic strategies and outcomes, following isolated gunshot wounds of the head, between military and civilian populations. BACKGROUND Recent military conflicts introduced new concepts in trauma care, including aggressive surgical intervention in severe head trauma. METHODS This was a cohort-matched study, using the civilian Trauma Quality Improvement Program (TQIP) database of the American College of Surgeons (ACS) and the Department of Defense Trauma Registry (DoDTR), during the period 2013 to 2016. Included in the study were patients with isolated gunshots to the head. Exclusion criteria were dead on arrival, civilians transferred from other hospitals, and patients with major extracranial associated injuries (body area Abbreviated Injury Scale >3). Patients in the military database were propensity score-matched 1:3 with patients in the civilian database. RESULTS A total of 136 patients in the DoDTR database were matched for age, sex, year of injury, and head Abbreviated Injury Scale with 408 patients from TQIP. Utilization of blood products was significantly higher in the military population ( P <0.001). In the military group, patients were significantly more likely to have intracranial pressure monitoring (17% vs 6%, P <0.001) and more likely to undergo craniotomy or craniectomy (34% vs 13%, P <0.001) than in the civilian group. Mortality in the military population was significantly lower (27% vs 38%, P =0.013). CONCLUSIONS Military patients are more likely to receive blood products, have intracranial pressure monitoring and undergo craniectomy or craniotomy than their civilian counterparts after isolated head gunshot wounds. Mortality is significantly lower in the military population. LEVEL OF EVIDENCE Level III-therapeutic.

Abstract
Objective Traumatic brain injury (TBI) leads to death and disability. This study developed an effective prognostic nomogram for assessing the risk factors for TBI mortality. Method Data were extracted from an online database called "Multiparameter Intelligent Monitoring in Intensive Care IV" (MIMIC IV). The ICD code obtained data from 2,551 TBI persons (first ICU stay, >18 years old) from this database. R divided samples into 7:3 training and testing cohorts. The univariate analysis determined whether the two cohorts differed statistically in baseline data. This research used forward stepwise logistic regression after independent prognostic factors for these TBI patients. The optimal variables were selected for the model by the optimal subset method. The optimal feature subsets in pattern recognition improved the model prediction, and the minimum BIC forest of the high-dimensional mixed graph model achieved a better prediction effect. A nomogram-labeled TBI-IHM model containing these risk factors was made by nomology in State software. Least Squares OLS was used to build linear models, and then the Receiver Operating Characteristic (ROC) curve was plotted. The TBI-IHM nomogram model's validity was determined by receiver operating characteristic curves (AUCs), correction curve, Hosmer-Lemeshow test, integrated discrimination improvement (IDI), net reclassification improvement (NRI), and decision-curve analysis (DCA). Result The eight features with a minimal BIC model were mannitol use, mechanical ventilation, vasopressor use, international normalized ratio, urea nitrogen, respiratory rate, and cerebrovascular disease. The proposed nomogram (TBI-IHM model) was the best mortality prediction model, with better discrimination and superior model fitting for severely ill TBI patients staying in ICU. The model's receiver operating characteristic curve (ROC) was the best compared to the seven other models. It might be clinically helpful for doctors to make clinical decisions. Conclusion The proposed nomogram (TBI-IHM model) has significant potential as a clinical utility in predicting mortality in TBI patients.

Abstract
BACKGROUND The Brain Trauma Foundation recommends intracranial pressure (ICP) monitoring in patients with severe traumatic brain injury (TBI). Race is associated with worse outcomes after TBI. The reasons for racial disparities in clinical decision-making around ICP monitor placement remain unclear. STUDY DESIGN We queried the TQIP database from 2017 to 2019 and included patients 16 years or older, with blunt severe TBI, defined as a head abbreviated injury score 3 or greater. Exclusion criteria were missing race, those without signs of life on admission, length of stay 1 day or less, and AIS of 6 in any body region. The primary outcome was ICP monitor placement, which was calculated using a Poisson regression model with robust SEs while adjusting for confounders. RESULTS A total of 260,814 patients were included: 218,939 White, 29,873 Black, 8,322 Asian, 2,884 American Indian, and 796 Native Hawaiian or Other Pacific Islander. Asian and American Indian patients had the highest rates of midline shift (16.5% and 16.9%). Native Hawaiian or Other Pacific Islanders had the highest rates of neurosurgical intervention (19.3%) and ICP monitor placement (6.5%). Asian patients were found to be 19% more likely to receive ICP monitoring (adjusted incident rate ratio 1.19; 95% CI 1.06 to 1.33; p = 0.003], and American Indian patients were 38% less likely (adjusted incident rate ratio 0.62; 95% CI 0.49 to 0.79; p < 0.001), compared with White patients, respectively. No differences were detected between White and Black patients. CONCLUSIONS ICP monitoring use differs by race. Further work is needed to elucidate modifiable causes of this difference in the management of severe TBI.

The Significance of Intracranial Pressure Monitoring for Reducing Mortality in Patients with Traumatic Brain Injury: A Systematic Review and Meta-Analysis. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:1956908. [PMID: 36254239 PMCID: PMC9569199 DOI: 10.1155/2022/1956908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 09/19/2022] [Accepted: 09/23/2022] [Indexed: 11/18/2022]
Abstract
Background Despite guidelines provided by the Brain Trauma Foundation (BTF) for treating patients with TBI, including advice to monitor intracranial pressure (ICP), the clinical application of ICP monitoring is far from universal. This laxity has been attributed to the relationship between mortality in TBI patients and ICP monitoring. Objective This systematic review and meta-analysis was aimed at determining the effect of intracranial pressure (ICP) monitoring on the mortality of patients with traumatic brain injury (TBI). Method A systematic search for articles was conducted on PubMed, Scopus, Cochrane Central Register of Control Trials (CENTRAL), and APA PsycNet for articles published from 1 January 2000 to 1 August 2022. Manager 5.4 was used to carry out statistical analysis. Results Article search yielded 1421 articles, but only 23 cohort studies were included in the systematic review and meta-analysis. The total number of study participants is 80,058. Seventeen studies reported unadjusted odds ratios (OR), and only 8 reported the adjusted odds ratio (OR). Nine out of seventeen studies reported an unadjusted OR of less than 1, and five out of eight studies reported an adjusted OR of less than 1. From this paper's analysis, the OR for in-hospital mortality was 1.01 [95% CI, 0.80, 1.28], with a p value of 0.92. OR for ICU mortality was 0.84 [95% CI, 0.52, 1.35], with a p value of 0.47. Conclusion But due to conflicting results, as evident above, it is unsatisfyingly challenging to draw any substantial conclusions from them. This paper thus calls for more research on this particular paper.

Neurointensive care of traumatic brain injury in the elderly-age-specific secondary insult levels and optimal physiological levels to target need to be defined. Acta Neurochir (Wien) 2022; 164:117-128. [PMID: 34757477 PMCID: PMC8761120 DOI: 10.1007/s00701-021-05047-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 10/25/2021] [Indexed: 10/26/2022]
Abstract
BACKGROUND Elderly patients with traumatic brain injury increase. Current targets and secondary insult definitions during neurointensive care (NIC) are mostly based on younger patients. The aim was therefore to study the occurrence of predefined secondary insults and the impact on outcome in different ages with particular focus on elderly. METHODS Patients admitted to Uppsala 2008-2014 were included. Patient characteristics, NIC management, monitoring data, and outcome were analyzed. The percentage of monitoring time for ICP, CPP, MAP, and SBP above-/below-predefined thresholds was calculated. RESULTS Five hundred seventy patients were included, 151 elderly ≥ 65 years and 419 younger 16-64 years. Age ≥ 65 had significantly higher percentage of CPP > 100, MAP > 120, and SBP > 180 and age 16-64 had higher percentage of ICP ≥ 20, CPP ≤ 60, and MAP ≤ 80. Age ≥ 65 contributed independently to the different secondary insult patterens. When patients in all ages were analyzed, low percentage of CPP > 100 and SBP > 180, respectively, was significant predictors of favorable outcome and high percentage of ICP ≥ 20, CPP > 100, SBP ≤ 100, and SBP > 180, respectively, was predictors of death. Analysis of age interaction showed that patients ≥ 65 differed and had a higher odds for favorable outcome with large proportion of good monitoring time with SBP > 180. CONCLUSIONS Elderly ≥ 65 have different patterns of secondary insults/physiological variables, which is independently associated to age. The finding that SBP > 180 increased the odds of favorable outcome in the elderly but decreased the odds in younger patients may indicate that blood pressure should be treated differently depending on age.

Abstract
BACKGROUND The Brain Trauma Foundation (BTF) Guidelines for the Management of Severe Traumatic Brain Injury (TBI) include intracranial pressure monitoring (ICPM), yet very little is known about ICPM in older adults. Our objectives were to characterize the utilization of ICPM in older adults and identify factors associated with ICPM in those who met the BTF guidelines. METHODS We analyzed data from the American Association for the Surgery of Trauma Geriatric TBI Study, a registry study conducted among individuals with isolated, CT-confirmed TBI across 45 trauma centers. The analysis was restricted to those aged ≥60. Independent factors associated with ICPM for those who did and did not meet the BTF guidelines were identified using logistic regression. RESULTS Our sample was composed of 2303 patients, of whom 66 (2.9%) underwent ICPM. Relative to Glasgow Coma Scale (GCS) score of 13 to 15, GCS score of 9 to 12 (OR 10.2; 95% CI 4.3 to 24.4) and GCS score of <9 (OR 15.0; 95% CI 7.2 to 31.1), intraventricular hemorrhage (OR 2.4; 95% CI 1.2 to 4.83), skull fractures (OR 3.6; 95% CI 2.0 to 6.6), CT worsening (OR 3.3; 95% CI 1.8 to 5.9), and neurosurgical interventions (OR 3.8; 95% CI 2.1 to 7.0) were significantly associated with ICPM. Restricting to those who met the BTF guidelines, only 43 of 240 (18%) underwent ICPM. Factors independently associated with ICPM included intraparenchymal hemorrhage (OR 2.2; 95% CI 1.0 to 4.7), skull fractures (OR 3.9; 95% CI 1.9 to 8.2), and neurosurgical interventions (OR 3.5; 95% CI 1.7 to 7.2). DISCUSSION Worsening GCS, intraparenchymal/intraventricular hemorrhage, and skull fractures were associated with ICPM among older adults with TBI, yet utilization of ICPM remains low, especially among those meeting the BTF guidelines, and potential benefits remain unclear. This study highlights the need for better understanding of factors that influence compliance with BTF guidelines and the risks versus benefits of ICPM in this population.

[PMID: 33905179 DOI: 10.1111/vec.13061] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 11/19/2019] [Accepted: 12/05/2019] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To determine whether an association exists between direct intracranial pressure (ICP) measurement and ultrasonographic measurement of optic nerve sheath diameter (ONSD) in anesthetized and standing horses. DESIGN Cross-sectional study performed on a convenience sample of healthy adult horses. SETTING University teaching hospital. ANIMALS Eight adult horses donated to the University. Enrolled horses were free of abnormalities on physical examination, CBC, neurological evaluation, and ophthalmological examination. MEASUREMENTS AND MAIN RESULTS Horses were anesthetized in lateral recumbency for placement of an ICP transducer. Three head positions (neutral, elevated, and lowered) were used to alter ICP. ICP and ONSD in 2 directions (D1 and D2) were recorded at 5 and 10 minutes after position change to elevated and lowered. ICP and ONSD measurements were repeated in standing sedated horses 24-36 hours after recovery from anesthesia. Linear regressions were performed with ICP as the dependent variable and ONSD as the independent variable by head position and times. Linear regressions were also performed for change from neutral under anesthesia, with ONSD as the independent variable and ICP as the dependent variable, by head position and times. Significance was set at P < 0.05. There was a moderate association between ICP and ONSD in horses with head lowered at 5 and 10 minutes (R2 values = 63%-78%) and weak association in head elevated at 10 minutes (R2 values = 56%-63%). There was a weak association between change from neutral ICP and change from neutral ONSD in the elevated anesthetized position at 10 minutes for summed D1 + D2 (R2 = 33%). CONCLUSIONS Consistent associations between direct ICP and ONSD in anesthetized or standing horses were not observed. This inconsistency limits the clinically utility of transpalpebral ultrasonographic ONSD measurement for ICP monitoring in horses.

Abstract
Intracranial hypertension (IH) is a clinical condition commonly encountered in the intensive care unit, which requires immediate treatment. The maintenance of normal intracranial pressure (ICP) and cerebral perfusion pressure in order to prevent secondary brain injury (SBI) is the central focus of management. SBI can be detected through clinical examination and invasive and non-invasive ICP monitoring. Progress in monitoring and understanding the pathophysiological mechanisms of IH allows the implementation of targeted interventions in order to improve the outcome of these patients. Initially, general prophylactic measures such as patient's head elevation, fever control, adequate analgesia and sedation depth should be applied immediately to all patients with suspected IH. Based on specific indications and conditions, surgical resection of mass lesions and cerebrospinal fluid drainage should be considered as an initial treatment for lowering ICP. Hyperosmolar therapy (mannitol or hypertonic saline) represents the cornerstone of medical treatment of acute IH while hyperventilation should be limited to emergency management of life-threatening raised ICP. Therapeutic hypothermia could have a possible benefit on outcome. To control elevated ICP refractory to maximum standard medical and surgical treatment, at first, high-dose barbiturate administration and then decompressive craniectomy as a last step are recommended with unclear and probable benefit on outcomes, respectively. The therapeutic strategy should be based on a staircase approach and be individualized for each patient. Since most therapeutic interventions have an uncertain effect on neurological outcome and mortality, future research should focus on both studying the long-term benefits of current strategies and developing new ones.

Abstract
OBJECTIVE The Brain Trauma Foundation (BTF) recommends intracranial pressure (ICP) monitoring for all salvageable patients with an abnormal computed tomography (CT) scan and a Glasgow Coma Scale <9. Studies have shown that compliance with this recommendation is low. We sought to obtain contemporary national rates of ICP monitor placement in patients with severe traumatic brain injury (TBI). METHODS Patients from the National Trauma Data Bank from 2013 to 2017 who met BTF criteria for ICP monitoring were included. Placement of an intraparenchymal ICP monitor or an external ventricular drain was queried. Binary logistic regression was used to determine factors that influenced the placement of an ICP monitor. RESULTS A total of 21,374 patients with severe TBI and an abnormal CT scan were included in the study. An ICP monitor was placed in 6543 patients (30.6%). ICP monitor placement increased modestly from 28.6% in 2013 to 32.8% in 2017. The pooled odds of ICP monitor placement between 2014 and 2017 were not different from 2013 (odds ratio, 1.04; 95% confidence interval, 0.99-1.09), but the adjusted odds of ICP monitor placement in 2017 were significantly greater (odds ratio, 1.18; 95% confidence interval, 1.06-1.30). Treatment at a teaching hospital, subdural hematoma, multiple intracranial abnormalities on CT, and greater Injury Severity Score were associated with ICP monitor placement, whereas older age was negatively associated with ICP monitor placement. CONCLUSIONS The rate of ICP monitoring in patients with severe TBI who meet BTF criteria is low and increased only slightly from 2013 to 2017.

Abstract
BACKGROUND Utilization of ICP monitors for pediatric patients is low and varies between centers. We hypothesized that in more severely injured patients (GCS 3-4), there would be a decreased mortality associated with invasive monitoring devices. METHODS The pediatric Trauma Quality Improvement Program (TQIP) was queried for patients aged ≤ 16 years meeting criteria for invasive monitors. Our primary outcome was mortality. Patients with ICP monitoring were compared to those without. A logistic regression was used to examine the risk of mortality. RESULTS Of 3,808 patients, 685 (18.0%) underwent ICP monitoring. ICP monitors were associated with increased risk of mortality (OR 1.82, CI 1.36-2.44, p < 0.001). A secondary analysis including type of invasive ICP monitor and dividing GCS into 3 categories revealed both intraventricular drain (OR 1.89, CI 1.3-2.7, p = 0.001) and intraparenchymal pressure monitor (OR 1.86, CI 1.32-2.6, p < 0.001) to be independently associated with an increased likelihood of mortality regardless of GCS, while intraparenchymal oxygen monitoring was not (OR 0.47, CI 0.11-2.05, p = 0.316). The strongest effect was seen in those patients with a GCS of 5-6. CONCLUSION ICP monitors are an independent risk factor for mortality, particularly with intraventricular drains and intraparenchymal monitors in patients with a GCS 5-6.

Abstract
OBJECTIVE The use of intracranial pressure (ICP) monitoring has been postulated to be beneficial in patients with severe traumatic brain injury (TBI), although studies investigating this hypothesis have reported conflicting results. The objective of this study was to evaluate the effect of inserting an ICP monitor on survival in patients with severe TBI. METHODS The Oslo University Hospital trauma registry was searched for the records of all patients admitted between January 1, 2002, and December 31, 2013, who fulfilled the Brain Trauma Foundation criteria for intracranial hypertension and who survived at least 24 hours after admission. The impact of ICP monitoring was investigated using both a logistic regression model and a multiple imputed, propensity score-weighted logistic regression analysis. RESULTS The study involved 1327 patients, in which 757 patients had an ICP monitor implanted. The use of ICP monitors significantly increased in the study period (p < 0.01). The 30-day overall mortality was 24.3% (322 patients), divided into 35.1% (200 patients, 95% confidence interval [CI] 31.3%-39.1%) in the group without an ICP monitor and 16.1% (122 patients, 95% CI 13.6%-18.9%) in the group with an ICP monitor. The impact of ICP monitors on 30-day mortality was found to be beneficial both in the complete case analysis logistic regression model (odds ratio [OR] 0.23, 95% CI 0.16-0.33) and in the adjusted, aggregated, propensity score-weighted imputed data sets (OR 0.22, 95% CI 0.15-0.35; both p < 0.001). The sensitivity analysis indicated that the findings are robust to unmeasured confounders. CONCLUSIONS The authors found that the use of an ICP monitor is significantly associated with improved survival in patients with severe head injury.

Abstract
This study aimed to investigate the clinical efficacy of intracranial pressure (ICP) monitoring regarding the perioperative management of patients with severe traumatic brain injury (sTBI). This was a cohort study performed between Jan 2013 and Jan 2016 and included all patients with sTBI. All patients were split into ICP monitoring and non-ICP monitoring groups. The primary outcomes were in-hospital mortality and Glasgow Outcome Scale (GOS) scores 6 months after injury, whereas the secondary outcomes include rate of successful nonsurgical treatment, rate of decompression craniotomy (DC), the length of stay in the ICU, and the hospital and medical expenses. This retrospective analysis included 246 ICP monitoring sTBI patients and 695 without ICP monitoring sTBI patients. No significant difference between groups regarding patient demographics. All patients underwent a GOS assessment 6 months after surgery. Compared to the non-ICP monitoring group, a lower in-hospital mortality (20.3% vs 30.2%, P < 0.01) and better GOS scores after 6 months (3.3 ± 1.6 vs 2.9 ± 1.6, P < 0.05) with ICP monitoring. In addition, patients in the ICP monitoring group had a lower craniotomy rate (41.1% vs 50.9%, P < 0.01) and a lower DC rate (41.6% vs 55.9%, P < 0.05) than those in the non-ICP monitoring group. ICU length of stay (12.4 ± 4.0 days vs 10.2 ± 4.8 days, P < 0.01) was shorter in the non-ICP monitoring group, but it had no difference between 2 groups on total length of hospital stay (22.9 ± 13.6 days vs 24.6 ± 13.6 days, P = 0.108); Furthermore, the medical expenses were significantly higher in the non-ICP monitoring group than the ICP monitoring group (11.5 ± 7.2 vs 13.3 ± 9.1, P < 0.01). Intracranial pressure monitoring has beneficial effects for sTBI during the perioperative period. It can reduce the in-hospital mortality and DC rate and also can improve the 6-month outcomes. However, this was a single institution and observational study, well-designed, multicenter, randomized control trials are needed to evaluate the effects of ICP monitoring for perioperative sTBI patients.

Abstract
Cerebral edema after brain injury can lead to brain damage and death if diagnosis and treatment are delayed. This study investigates the feasibility of employing electrical impedance tomography (EIT) as a non-invasive imaging tool for monitoring the development of cerebral edema, in which impedance imaging of the brain related to brain water content is compared with intracranial pressure (ICP). We enrolled forty patients with cerebral hemorrhage who underwent lateral external ventricular drain with intraventricular ICP and EIT monitoring for 3 h after initiation of dehydration treatment. The average reconstructed impedance value (ARV) calculated from EIT images was compared with ICP. Dehydration effects induced changes in ARV and ICP showed a close negative correlation in all patients, and the mean correlation reached R2 = 0.78 ± 0.16 (p < .001). A regression equation (R2 = 0.62, p < .001) was formulated from the total of measurement data. The 95% limits of agreement were - 6.13 to 6.13 mmHg. Adaptive clustering and variance analysis of normalized changes in ARV and ICP showed 92.5% similarity and no statistically significant differences (p > .05). Moreover, the sensitivity, specificity and area under the curve of changes in ICP >10 mmHg were 0.65, 0.73 and 0.70 respectively. The findings show that EIT can monitor changes in brain water content associated with cerebral edema, which could provide a real-time and non-invasive imaging tool for early identification of cerebral edema and the evaluation of mannitol dehydration.

Abstract
BACKGROUND The Brain Trauma Foundation recommends intracranial pressure (ICP) monitor placement for patients with severe traumatic brain injury (TBI). Adherence with these guidelines in elderly patients is unknown. We hypothesized that disparities in ICP monitor placement would exist based on patient age. METHODS Using the National Trauma Data Bank (2010-2014), we identified patients admitted for blunt TBI with admission Glasgow Coma Scale (GCS) scores of 3-8. Patients were excluded if they had a non-Head Abbreviated Injury Scale (AIS) score ≥3, hospital length of stay <24 hours or were discharged from the emergency department. Demographic data, ICP monitor placement, GCS, AIS-Head, Injury Severity Score, and outcome measures were collected. Propensity score matching between ICP monitor and non-ICP monitor patients was used for logistic regression and Cox multivariate regression analyses. RESULTS Of the 30 710 patients with blunt TBI with GCS scores of 3-8 included in our study, 4093 were treated with an ICP monitor. ICP monitor placement rates significantly decreased with increasing age. Multivariable analysis demonstrated that patients treated with an ICP monitor were more likely to be younger, male, have private/commercial insurance, and receive care at an institution with three or more neurosurgeons. CONCLUSION Patients ≥65 years of age with severe blunt TBI are less likely to be treated with an ICP monitor than younger patients. Age disparities in adherence to Brain Trauma Foundation guidelines may alter the outcomes for patients with severe TBI. LEVEL OF EVIDENCE Level IV.

Abstract
Traumatic brain injury (TBI) is often associated with long-term disability and chronic neurological sequelae. One common contributor to unfavorable outcomes is secondary brain injury, which is potentially treatable and preventable through appropriate management of patients in the neurosurgical intensive care unit. Intracranial pressure (ICP) is currently the predominant neurological-specific physiological parameter used to direct the care of severe TBI (sTBI) patients. However, recent clinical evidence has called into question the association of ICP monitoring with improved clinical outcome. The detailed cellular and molecular derangements associated with intracranial hypertension (IC-HTN) and their relationship to injury phenotype and neurological outcomes are not completely understood. Various animal models of TBI have been developed, but the clinical applicability of ICP monitoring in the pre-clinical setting has not been well-characterized. Linking basic mechanistic studies in translational TBI models with investigation of ICP monitoring that more faithfully replicates the clinical setting will provide clinical investigators with a more informed understanding of the pathophysiology of IC-HTN, thus facilitating development of improved therapies for sTBI patients.

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
PURPOSE OF REVIEW Intracranial pressure (ICP) monitoring and treatment is central in the management of traumatic brain injury. Despite 4 decades of clinical use, several aspects remain controversial, including the indications for ICP and treatment options. RECENT FINDINGS Two major trials tested surgical decompression and mild hypothermia as treatments for high ICP. Both were rigorous, randomized, multicenter studies, with different designs. Decompression was tested for ICP refractory to conventional treatment, whereas hypothermia was offered as an alternative to conventional medical therapy. Decompression reduced mortality, but at the expense of more disability. The hypothermia trial was stopped because of a worse outcome in the treated arm. Indications for ICP monitoring have been reviewed and new international guidelines issued. New contributions published in 2016 have dealt with computerized analysis for predicting ICP crises; noninvasive or innovative methods for measuring ICP; reassessment of standard therapeutic interventions, such as hypertonic solutions and the level of intensity of ICP therapy. SUMMARY Aggressive strategies for ICP control, like surgical decompression or hypothermia, carefully tested, have controversial effects on outcome. Several articles have made worthwhile contributions to important clinical issues, but with no real breakthroughs.

Abstract
This review of the literature on traumatic brain injury (TBI) in older adults focuses on incident TBI sustained in older adulthood ("geriatric TBI") rather than on the separate, but related, topic of older adults with a history of earlier-life TBI. We describe the epidemiology of geriatric TBI, the impact of comorbidities and pre-injury function on TBI risk and outcomes, diagnostic testing, management issues, outcomes, and critical directions for future research. The highest incidence of TBI-related emergency department visits, hospitalizations, and deaths occur in older adults. Higher morbidity and mortality rates among older versus younger individuals with TBI may contribute to an assumption of futility about aggressive management of geriatric TBI. However, many older adults with TBI respond well to aggressive management and rehabilitation, suggesting that chronological age and TBI severity alone are inadequate prognostic markers. Yet there are few geriatric-specific TBI guidelines to assist with complex management decisions, and TBI prognostic models do not perform optimally in this population. Major barriers in management of geriatric TBI include under-representation of older adults in TBI research, lack of systematic measurement of pre-injury health that may be a better predictor of outcome and response to treatment than age and TBI severity alone, and lack of geriatric-specific TBI common data elements (CDEs). This review highlights the urgent need to develop more age-inclusive TBI research protocols, geriatric TBI CDEs, geriatric TBI prognostic models, and evidence-based geriatric TBI consensus management guidelines aimed at improving short- and long-term outcomes for the large and growing geriatric TBI population.

Abstract
OBJECTIVE To investigate clinical efficacy of and optimal therapeutic strategy for ventricular intracranial pressure monitoring (V-ICPM) in patients with traumatic bifrontal contusions (TBCs). METHODS From 8760 patients with traumatic brain injury treated between January 2010 and January 2016, a retrospective analysis was performed on 105 patients with TBCs who underwent V-ICPM and 282 patients with TBCs who did not. All patients underwent treatment at the 101st Hospital of PLA, Wuxi, China. Rates of successful conservative treatment, decompressive craniectomy, and bifrontal craniotomy; incidence of neurologic dysfunction; length of stay; and medical expenses were compared between groups. RESULTS Glasgow Outcome Scale was used to assess all patients during follow-up (range, 6 months to 5.5 years). There were no significant differences in prognosis between the 2 groups (P = 0.100). Compared with the patients who did not undergo V-ICPM, the V-ICPM group had a significantly better successful conservative treatment rate (64.8% vs. 47.2%, P = 0.002), decompressive craniectomy rate (8.1% vs. 22.1%, P = 0.008), and bifrontal craniotomy rate (5.7% vs. 15.6%, P = 0.01); shorter length of stay (P = 0.000); and lower medical expenses (P = 0.004). CONCLUSIONS Patients with TBCs should be strictly, closely, and dynamically observed by neurosurgery intensive care unit physicians and nurses. Patients should undergo ventricular intracranial pressure probe implantation in a timely manner. V-ICPM can help optimize treatment. Although V-ICPM did not significantly improve the prognosis of patients, it had many other advantages. V-ICPM warrants further clinical research and may be beneficial for patients with TBCs.

Abstract
Intracranial pressure (ICP) monitoring is a staple of neurocritical care. The most commonly used current methods of monitoring in the acute setting include fluid-based systems, implantable transducers and Doppler ultrasonography. It is well established that management of elevated ICP is critical for clinical outcomes. However, numerous studies show that current methods of ICP monitoring cannot reliably define the limit of the brain's intrinsic compensatory capacity to manage increases in pressure, which would allow for proactive ICP management. Current work in the field hopes to address this gap by harnessing live-streaming ICP pressure-wave data and a multimodal integration with other physiologic measures. Additionally, there is continued development of non-invasive ICP monitoring methods for use in specific clinical scenarios.

Abstract
BACKGROUND Brain Trauma Foundation (BTF) guidelines recommend intracranial pressure (ICP) monitoring in patients who sustained severe traumatic brain injury (TBI). Compliance to BTF guidelines is variable, and the effect of ICP monitoring on outcomes remains a controversial issue. The purpose of this study was to assess guidelines compliance in patients who sustain a severe TBI and to analyze the effect of ICP monitoring on outcomes. METHODS Trauma Quality Improvement Program database study, which included patients with isolated severe blunt head trauma (head Abbreviated Injury Scale ≥3 with Glasgow Coma Scale <9). Patients with severe extracranial injuries excluded. Analyzed variables were demographics, comorbidities, mechanism of injuries, head injury specifics, AIS for each body area, Injury Severity Score, admission vital signs, placement of ICP catheter and craniectomy. Multivariate analysis was used to identify independent predictors for outcomes, overall and in the groups of patients with head AIS 3, 4 or 5. RESULTS During the study period 13,188 patients with isolated severe TBI met the BTF guidelines for ICP monitoring. An ICP catheter was placed in 1519 (11.5%) patients. Stepwise logistic regression analysis identified age ≥65 years, hypotension on admission, AIS 4 and AIS 5 as independent predictors for mortality. ICP monitoring was not an independent protective variable in terms of mortality (OR 1.12; 95% CI, 0.983-1.275; p = 0.088). Overall, ICP monitor placement was independently associated with increased overall complications (OR 2.089; 95% CI, 1.85-2.358; p < 0.001), infectious complications (OR 2.282; 95% CI, 2.015-2.584; p < 0.001) and poor functional independence (OR 1.889; 95% CI, 1.575-2.264; p < 0.001). Sub analysis of the groups of patients with head AIS 3, 4, and 5 failed to show any protective effect of ICP monitors against mortality. In the group of patients with head AIS 4, ICP placement was an independent predictor of mortality (OR 2206; 95% CI, 1652-2948; p < 0.001). CONCLUSIONS Compliance with the BTF guidelines for ICP monitoring is poor. ICP monitoring does not have any survival benefit in patients with isolated severe blunt TBI and is associated with more complications and increased utilization of hospital resources.

Abstract
BACKGROUND Sedation therapy is vital for treating severe traumatic brain injury (TBI). Yet, types of sedation assessment tools and sedation levels that are suitable for sedation treatment have not been investigated. OBJECTIVE To investigate the influence of different sedation levels guided by the Bispectral Index (BIS) on the therapeutic effects for severe TBI. METHODS According to inclusion, exclusion, and rejection criteria, 35 patients were prospectively included and divided into Richmond Agitation Sedation Scale (RASS), BIS(I), and BIS(II) groups. The RASS group was controlled the level of sedation to within -2 or -3, and the BIS(I) and (II) groups within the range of 40-50 and 50-60, respectively. In addition to clinical data, RASS, BIS, and intracranial pressure (ICP) values were collected. RASS and ICP variability were introduced to investigate the different of sedative control effect with or without BIS monitor, and the control effect of ICP between different sedation levels. Statistical analysis was performed to estimate the effectiveness of different sedation levels guided by BIS in sedation treatment within 72 hours. RESULTS There were no significant differences in demographics among the 3 groups. RASS variability of the BIS(I) and (II) groups was significantly lower than that of the RASS group (P < 0.05), and in the BIS(I) group it was insignificantly lower than in the BIS(II) group. The ICP of the BIS(I) and (II) groups declined to <13.5 mm Hg significantly earlier than that of the RASS group (P < 0.05), and the difference between BIS(I) and (II) was insignificant. ICP variability of RASS group was higher than those of the BIS(I) and (II) groups (P < 0.05), and ICP variability of the BIS(I) group was significantly lower than that of the BIS(II) group (P < 0.05). Differences in days in the neurosurgery intensive care unit and outcomes among the 3 groups were insignificant. CONCLUSIONS BIS is more reliable than RASS for maintaining a stable sedation status and ICP. Deeper sedation levels (BIS 40-50) cause ICP to decrease more quickly, with lower ICP variability.

Abstract
INTRODUCTION The Brain Trauma Foundation (BTF) recently updated recommendations for intracranial pressure (ICP) monitoring in severe traumatic brain injury (TBI). The effect of ICP monitoring on outcomes is controversial, and compliance with BTF guidelines is variable. The purpose of this study was to assess both compliance and outcomes at level I trauma centers. MATERIALS AND METHODS The American College of Surgeons Trauma Quality Improvement Program database was queried for all patients admitted to level I trauma centers with isolated blunt severe TBI (AIS>3, GCS<9) who met criteria for ICP monitoring. Patients who had severe extracranial injuries, craniectomy, or death in the first 24h were excluded. Comparison between groups with and without ICP monitoring was made, analyzing demographics, comorbidities, mechanism of injury, head Abbreviated Injury Scale (AIS), vital signs on admission, head CT scan findings. Outcomes included in-hospital mortality, mechanical ventilation days, intensive care unit (ICU) length of stay, hospital length of stay, systemic complications, and functional independence at discharge. Multivariable analysis was used to identify independent risk factors for each of the outcomes. RESULTS Overall, 4880 patients were included. ICP monitoring was used in 529 patients (10.8%). Stepwise logistic regression analysis identified ICP monitor placement as an independent risk factor for mortality (OR 1.63; 95% CI 1.28-2.07; p<0.001), mechanical ventilation (OR 5.74 95% CI 4.42-7.46; p<0.001), ICU length of stay (OR 4.03; 95% CI 2.94-5.52; p<0.001), systemic complications (OR 2.78; 95% CI 2.29-3.37; p<0.001), and decreased functional independence at discharge (OR 1.71 95% CI 1.29-2.26; p<0.001). Subgroup analysis of patients with head AIS 3, 4, and 5 confirmed that ICP monitors remained an independent risk factor for mortality in both head AIS 4 and 5. CONCLUSIONS Compliance with BTF guidelines for ICP monitoring is low, even at level I trauma centers. In this study, ICP monitoring was associated with poor outcomes, and was found to be an independent risk factor for mortality. Further studies are needed to determine the optimal role of ICP monitoring in the management of severe TBI.
