<h4>Background/objective</h4>Severe acute brain injury (SABI) is responsible for 12 million deaths annually, prolonged disability in survivors, and substantial resource utilization. Little guidance exists regarding indication or optimal timing of tracheostomy after SABI. Our aims were to determine national trends in tracheostomy utilization among mechanically ventilated patients with SABI in the USA, as well as to examine factors associated with tracheostomy utilization following SABI.<h4>Method ...[more]

Project description:ObjectiveTo synthesize reported long-term outcomes in patients undergoing tracheostomy after severe acute brain injury (SABI).MethodsWe systematically searched PubMed, EMBASE, and Cochrane Library for studies in English, German, and Spanish between 1990 and 2019, reporting outcomes in patients with SABI who underwent tracheostomy. We adhered to the preferred reporting items for systematic reviews and meta-analyses guidelines and the meta-analyses of observational studies in epidemiology guidelines. We excluded studies reporting on less than 10 patients, mixed populations with other neurological diseases, or studies assessing highly select subgroups defined by age or procedures. Data were extracted independently by two investigators. Results were pooled using random effects modeling. The primary outcome was long-term functional outcome (mRS or GOS) at 6-12 months. Secondary outcomes included hospital and long-term mortality, decannulation rates, and discharge home rates.ResultsOf 1405 studies identified, 61 underwent full manuscript review and 19 studies comprising 35,362 patients from 10 countries were included in the meta-analysis. The primary outcome was available from five studies with 451 patients. At 6-12 months, about one-third of patients (30%; 95% confidence interval [CI] 17-48) achieved independence, and about one-third survived in a dependent state (36%, 95% CI 28-46%). The pooled short-term mortality for 19,048 patients was 12%, (95% CI 9-17%) with no significant difference between stroke (10%) and TBI patients (13%), and the pooled long-term mortality was 21% (95% CI 11-36). Decannulation occurred in 79% (95% CI 51-93%) of survivors. Heterogeneity was high for most outcome assessments (I2 > 75%).ConclusionsOur findings suggest that about one in three patients with SABI who undergo tracheostomy may eventually achieve independence. Future research is needed to understand the reasons for the heterogeneity between studies and to identify those patients with promising outcomes as well as factors influencing outcome.

Project description:BackgroundTracheostomy represents one important and value-laden treatment decision after severe acute brain injury (SABI). Whether to pursue this life-sustaining treatment typically hinges on intense conversations between family and clinicians. The aim of this study was, among a cohort of patient who had undergone tracheostomy after SABI, to explore the long-term reflections of patients and their families as they look back on this decision.MethodsFor this qualitative study, we reviewed the electronic medical records of patients with SABI who underwent tracheostomy. We included all patients who were admitted to our 30-bed neuro-intensive care unit with SABI and underwent tracheostomy between November 2017 and October 2019. Using purposive sampling, we invited survivors and family members to participate in telephone interviews greater than 3 months after SABI until thematic saturation was reached. Interviews were audiotaped, transcribed, and analyzed by using thematic analysis.ResultsOverall, 38 patients with SABI in the neuro-intensive care unit underwent tracheostomy. The mean age of patients was 49 (range 18-81), with 19 of 38 patients diagnosed with traumatic brain injury and 19 of 38 with stroke. We interviewed 20 family members of 18 of 38 patients at a mean of 16 (SD 9) months after hospitalization. The mean patient age among those with an interview was 50 (range 18-76); the mean modified Rankin Scale score (mRS) was 4.7 (SD 0.8) at hospital discharge. At the time of the interview, ten patients lived at home and two in a skilled nursing facility and had a mean mRS of 2.6 (SD 0.9), and six had died. As families reflected on the decision to proceed with a tracheostomy, two themes emerged. First, families did not remember tracheostomy as a choice because the uncertain chance of recovery rendered the certain alternative of death unacceptable or because they valued survival above all and therefore could not perceive an alternative to life-sustaining treatment. Second, families identified a fundamental need to receive supportive, consistent communication centering around compassion, clarity, and hope. When this need was met, families were able to reflect on the tracheostomy decision with peace, regardless of their loved one's eventual outcome.ConclusionsAfter SABI, prognostic uncertainty almost transcends the concept of choice. Families who proceeded with a tracheostomy saw it as the only option at the time. High-quality communication may mitigate the stress surrounding this high-stakes decision.

Project description:BACKGROUND:Early tracheostomy has been associated with shorter hospital stay and fewer complications in adult trauma patients. Guidelines for tracheostomy have not been established for children with severe traumatic brain injury (TBI). The purpose of this study was to (1) define nationwide trends in time to extubation and time to tracheostomy and (2) determine if early tracheostomy is associated with decreased length of stay and fewer complications in children with severe TBI. METHODS:Records of children (<15 years) with severe TBI (head Abbreviated Injury Severity [AIS] score ?3) who were mechanically ventilated (>48 hours) were obtained from the National Trauma Data Bank (2007-2015). Outcomes after early (?14 days) and late (?15 days) tracheostomy placement were compared using 1:1 propensity score matching to control for potential confounding by indication. Propensity scores were calculated based on age, race, pulse, blood pressure, Glasgow Coma Scale motor score, injury mechanism, associated injury Abbreviated Injury Severity scores, TBI subtype, craniotomy, and intracranial pressure monitor placement. RESULTS:Among 6,101 children with severe TBI, 5,740 (94%) were extubated or died without tracheostomy, 95% of the time within 18 days. Tracheostomy was performed in 361 children (6%) at a median [interquartile range] of 15 [10, 22] days. Using propensity score matching, we compared 121 matched pairs with early or late tracheostomy. Early tracheostomy was associated with fewer ventilator days (14 [9, 19] vs. 25 [19, 35]), intensive care unit days (19 [14, 25] vs. 31 [24, 43]), and hospital days (26 [19, 41] vs. 39 [31, 54], all p < 0.05). Pneumonia (24% vs. 41%), venous thromboembolism (3% vs. 13%), and decubitus ulcer (4% vs. 13%) occurred less frequently with early tracheostomy (p < 0.05). CONCLUSIONS:Early tracheostomy is associated with shorter hospital stay and fewer complications among children with severe TBI. Extubation without tracheostomy is rare beyond 18 days after injury.

Project description:IntroductionSevere brain injury (SBI), including severe intraventricular haemorrhage (sIVH) and cystic periventricular leukomalacia, poses significant challenges for preterm infants, yet recent data and trends are limited.MethodsAnalyses were conducted using the Australian and New Zealand Neonatal Network data on preterm infants born <32 weeks' gestation admitted at Monash Children's Hospital, Australia, from January 2014 to April 2021. The occurrence and trends of SBI and sIVH among preterm infants, along with the rates and trends of death and neurodevelopmental impairment (NDI) in SBI infants were assessed.ResultsOf 1,609 preterm infants, 6.7% had SBI, and 5.6% exhibited sIVH. A total of 37.6% of infants with SBI did not survive to discharge, with 92% of these deaths occurring following redirection of clinical care. Cerebral palsy was diagnosed in 65.2% of SBI survivors, while 86.4% of SBI survivors experienced NDI. No statistically significant differences were observed in the temporal trends of SBI (adjusted OR [95% CI] 1.08 [0.97-1.20]; p = 0.13) or sIVH (adjusted OR [95% CI] 1.09 [0.97-1.21]; p = 0.11). Similarly, there was no statistically significant difference noted in the temporal trend of the composite outcome, which included death or NDI among infants with SBI (adjusted OR [95% CI] 0.90 [0.53-1.53]; p = 0.71).ConclusionNeither the rates of SBI nor its associated composite outcome of death or NDI improved over time. A notable proportion of preterm infants with SBI faced redirection of care and subsequent mortality, while most survivors exhibited adverse neurodevelopmental challenges. The development of better therapeutic interventions is imperative to improve outcomes for these vulnerable infants.

Project description:BackgroundAcute respiratory distress syndrome (ARDS) is common after traumatic brain injury (TBI) and is associated with worse neurologic outcomes and longer hospitalization. However, the incidence and associated causes of ARDS in isolated TBI have not been well studied.MethodsWe performed a subgroup analysis of 210 consecutive patients with isolated severe TBI enrolled in a prospective observational cohort at a Level 1 trauma center between 2005 and 2014. Subjects required endotracheal intubation and had isolated severe TBI defined by a head Abbreviated Injury Scale (AIS) score of 3 or greater and AIS score lower than 3 in all other categories. ARDS within the first 8 days of admission was rigorously adjudicated using Berlin criteria. Regression analyses were used to test the association between predictors of interest and ARDS.ResultsThe incidence of ARDS in the first 8 days after severe isolated TBI was 30%. Patients who developed ARDS were administered more crystalloids (4.3 L vs. 3.5 L, p = 0.005) and blood products in the first 12 hours of admission. Patients with ARDS had significantly worse clinical outcomes measured at 28 days, including longer median intensive care unit and hospital stays (4 days vs. 13 days, p < 0.001, and 7.5 days vs. 14.5 days, p < 0.001, respectively). In unadjusted logistic regression analyses, the odds of developing ARDS were significantly associated with head AIS score (odds ratio [OR], 1.8; p = 0.018), male sex (OR, 2.9; p = 0.012), and early transfusion of platelets (OR, 2.8; p = 0.003). These associations were similar in a multivariate logistic regression model.ConclusionIn the era of balanced hemostatic resuscitation practices, severity of head injury, male sex, early crystalloids, and early transfusion of platelets are associated with a higher risk of ARDS after severe isolated TBI. Early transfusion of platelets after severe TBI may be a modifiable risk factor for ARDS, and these findings invite further investigation into causal mechanisms driving this observed association.Level of evidencePrognostic/epidemiologic study, level III.

Project description:Tools assaying the neural networks that modulate consciousness may facilitate tracking of recovery after acute severe brain injury. The ABCD framework classifies resting-state EEG into categories reflecting levels of thalamocortical network function that correlate with outcome in post-cardiac arrest coma. In this longitudinal cohort study, we applied the ABCD framework to 20 patients with acute severe traumatic brain injury requiring intensive care (12 of whom were also studied at ≥6-months post-injury) and 16 healthy controls. We tested four hypotheses: 1) EEG ABCD classifications are spatially heterogeneous and temporally variable; 2) ABCD classifications improve longitudinally, commensurate with the degree of behavioral recovery; 3) ABCD classifications correlate with behavioral level of consciousness; and 4) the Coma Recovery Scale-Revised arousal facilitation protocol yields improved ABCD classifications. Channel-level EEG power spectra were classified based on spectral peaks within pre-defined frequency bands: 'A' = no peaks above delta (<4 Hz) range (complete thalamocortical disruption); 'B' = theta (4-8 Hz) peak (severe thalamocortical disruption); 'C' = theta and beta (13-24 Hz) peaks (moderate thalamocortical disruption); or 'D' = alpha (8-13 Hz) and beta peaks (normal thalamocortical function). Acutely, 95% of patients demonstrated 'D' signals in at least one channel but exhibited within-session temporal variability and spatial heterogeneity in the proportion of different channel-level ABCD classifications. By contrast, healthy participants and patients at follow-up consistently demonstrated signals corresponding to intact thalamocortical network function. Patients demonstrated longitudinal improvement in ABCD classifications (p < .05) and ABCD classification distinguished patients with and without command-following in the subacute-to-chronic phase of recovery (p < .01). In patients studied acutely, ABCD classifications improved after the Coma Recovery Scale-Revised arousal facilitation protocol (p < .05) but did not correspond with behavioral level of consciousness. These findings support the use of the ABCD framework to characterize channel-level EEG dynamics and track fluctuations in functional thalamocortical network integrity in spatial detail.

Project description:Background: Tracheostomy is a widespread procedure usually performed with a percutaneous approach for prolonged mechanical ventilation. Little is known about the population-based trends for percutaneous tracheostomies (PT). The aim of this study was to evaluate the order to analyze the characteristics, rates, and costs of PTs performed in Italy from 2009 to 2014. Methods: We analyzed 102,646 PTs performed in Italy between 2009 and 2014. We obtained the data of patients from the section of the discharge report of the Italian Ministry of Health (National Archive for Hospital Discharge Form, Ministry of Health) about age, gender, length of stay (LOS), hospital types, and hospital region for code 541 and 542 for the years 2009, 2010, 2011, 2012, 2013 and 2014. Our additional source of data was the Annual Discharge Reports of the Italian Ministry of Health. Results: In this study, including 102,646 PTs performed from 2009 to 2014, we found that (1) the rates of PTs significantly decreased over time; (2) PTs were mostly performed in patients aged less than 65 years and hospitalized in ICUs for less than 40 days; and (3) the costs of PTs severely decreased over time, with a breakpoint between 2011 and 2012. Conclusions: Percutaneous tracheostomy is still a procedure frequently performed in the setting of acute care. Although percutaneous tracheostomy still results in high medical care reimbursement, it is a safe and cost-saving procedure.

Project description:BackgroundCognitive impairments commonly occur after traumatic brain injury (TBI) and affect daily functioning. Cortisol levels, which are elevated during acute hospitalization for most individuals after severe TBI, can influence cognition, but this association has not been studied previously in TBI.ObjectiveWe hypothesized that serum and cerebral spinal fluid (CSF) cortisol trajectories over days 0-5 post-injury are associated with cognition 6-month post-injury.MethodsWe examined 94 participants with severe TBI, collected acute serum and/or CSF samples over days 0-5 post-injury, and compared cortisol levels to those in 17 healthy controls. N = 88 participants had serum, and n = 84 had CSF samples available for cortisol measurement and had neuropsychological testing 6 months post-injury. Group based trajectory analysis (TRAJ) was used to generate temporal serum and CSF cortisol profiles which were examined for associations with neuropsychological performance. We used linear regression to examine relationships between cortisol TRAJ groups and both overall and domain-specific cognition.ResultsTRAJ analysis identified a high group and a decliner group for serum and a high group and low group for CSF cortisol. Multivariable analysis showed serum cortisol TRAJ group was associated with overall cognitive composites scores (P = .024) and with executive function (P = .039) and verbal fluency (P = .029) domain scores. CSF cortisol TRAJ group was associated with overall cognitive composite scores (P = .021) and domain scores for executive function (P = .041), verbal fluency (P = .031), and attention (P = .034).ConclusionsHigh acute cortisol trajectories are associated with poorer cognition 6 months post-TBI.

Project description:See Schiff (doi:10.1093/awx209) for a scientific commentary on this article. Patients with acute severe traumatic brain injury may recover consciousness before self-expression. Without behavioural evidence of consciousness at the bedside, clinicians may render an inaccurate prognosis, increasing the likelihood of withholding life-sustaining therapies or denying rehabilitative services. Task-based functional magnetic resonance imaging and electroencephalography techniques have revealed covert consciousness in the chronic setting, but these techniques have not been tested in the intensive care unit. We prospectively enrolled 16 patients admitted to the intensive care unit for acute severe traumatic brain injury to test two hypotheses: (i) in patients who lack behavioural evidence of language expression and comprehension, functional magnetic resonance imaging and electroencephalography detect command-following during a motor imagery task (i.e. cognitive motor dissociation) and association cortex responses during language and music stimuli (i.e. higher-order cortex motor dissociation); and (ii) early responses to these paradigms are associated with better 6-month outcomes on the Glasgow Outcome Scale-Extended. Patients underwent functional magnetic resonance imaging on post-injury Day 9.2 ± 5.0 and electroencephalography on Day 9.8 ± 4.6. At the time of imaging, behavioural evaluation with the Coma Recovery Scale-Revised indicated coma (n = 2), vegetative state (n = 3), minimally conscious state without language (n = 3), minimally conscious state with language (n = 4) or post-traumatic confusional state (n = 4). Cognitive motor dissociation was identified in four patients, including three whose behavioural diagnosis suggested a vegetative state. Higher-order cortex motor dissociation was identified in two additional patients. Complete absence of responses to language, music and motor imagery was only observed in coma patients. In patients with behavioural evidence of language function, responses to language and music were more frequently observed than responses to motor imagery (62.5-80% versus 33.3-42.9%). Similarly, in 16 matched healthy subjects, responses to language and music were more frequently observed than responses to motor imagery (87.5-100% versus 68.8-75.0%). Except for one patient who died in the intensive care unit, all patients with cognitive motor dissociation and higher-order cortex motor dissociation recovered beyond a confusional state by 6 months. However, 6-month outcomes were not associated with early functional magnetic resonance imaging and electroencephalography responses for the entire cohort. These observations suggest that functional magnetic resonance imaging and electroencephalography can detect command-following and higher-order cortical function in patients with acute severe traumatic brain injury. Early detection of covert consciousness and cortical responses in the intensive care unit could alter time-sensitive decisions about withholding life-sustaining therapies.

Project description:ObjectThe aim of the study was to evaluate the early changes in pituitary hormone levels after severe traumatic brain injury (sTBI) and compare hormone levels to basic neuro-intensive care data, a systematic scoring of the CT-findings and to evaluate whether hormone changes are related to outcome.MethodsProspective study, including consecutive patients, 15-70 years, with sTBI, Glasgow Coma Scale (GCS) score ≤ 8, initial cerebral perfusion pressure > 10 mm Hg, and arrival to our level one trauma university hospital within 24 hours after head trauma (n = 48). Serum samples were collected in the morning (08-10 am) day 1 and day 4 after sTBI for analysis of cortisol, growth hormone (GH), prolactin, insulin-like growth factor 1 (IGF-1), thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), follicular stimulating hormone (FSH), luteinizing hormone (LH), testosterone and sex hormone-binding globulin (SHBG) (men). Serum for cortisol and GH was also obtained in the evening (17-19 pm) at day 1 and day 4. The first CT of the brain was classified according to Marshall. Independent staff evaluated outcome at 3 months using GOS-E.ResultsProfound changes were found for most pituitary-dependent hormones in the acute phase after sTBI, i.e. low levels of thyroid hormones, strong suppression of the pituitary-gonadal axis and increased levels of prolactin. The main findings of this study were: 1) A large proportion (54% day 1 and 70% day 4) of the patients showed morning s-cortisol levels below the proposed cut-off levels for critical illness related corticosteroid insufficiency (CIRCI), i.e. <276 nmol/L (=10 ug/dL), 2) Low s-cortisol was not associated with higher mortality or worse outcome at 3 months, 3) There was a significant association between early (day 1) and strong suppression of the pituitary-gonadal axis and improved survival and favorable functional outcome 3 months after sTBI, 4) Significantly lower levels of fT3 and TSH at day 4 in patients with a poor outcome at 3 months. 5) A higher Marshall CT score was associated with higher day 1 LH/FSH- and lower day 4 TSH levels 6) In general no significant correlation between GCS, ICP or CPP and hormone levels were detected. Only ICPmax and LH day 1 in men was significantly correlated.ConclusionProfound dynamic changes in hormone levels are found in the acute phase of sTBI. This is consistent with previous findings in different groups of critically ill patients, most of which are likely to be attributed to physiological adaptation to acute illness. Low cortisol levels were a common finding, and not associated with unfavorable outcome. A retained ability to a dynamic hormonal response, i.e. fast and strong suppression of the pituitary-gonadal axis (day 1) and ability to restore activity in the pituitary-thyroid axis (day 4) was associated with less severe injury according to CT-findings and favorable outcome.
