Timing of tracheostomy placement among children with severe traumatic brain injury: A propensity-matched analysis.

ABSTRACT: 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. LEVEL OF EVIDENCE:Prognostic and epidemiological, retrospective comparative study, level III.

Project description:BackgroundPatients with acute traumatic cervical or high thoracic level spinal cord injury (SCI) typically require mechanical ventilation (MV) during their acute admission. Placement of a tracheostomy is preferred when prolonged weaning from MV is anticipated. However, the optimal timing of tracheostomy placement in patients with acute traumatic SCI remains uncertain. We systematically reviewed the literature to determine the effects of early versus late tracheostomy or prolonged intubation in patients with acute traumatic SCI on important clinical outcomes.MethodsSix databases were searched from their inception to January 2020. Conference abstracts from relevant proceedings and the gray literature were searched to identify additional studies. Data were obtained by two independent reviewers to ensure accuracy and completeness. The quality of observational studies was evaluated using the Newcastle Ottawa Scale.ResultsSeventeen studies (2,804 patients) met selection criteria, 14 of which were published after 2009. Meta-analysis showed that early tracheostomy was not associated with decreased short-term mortality (risk ratio [RR], 0.84; 95% confidence interval [CI], 0.39-1.79; p = 0.65; n = 2,072), but was associated with a reduction in MV duration (mean difference [MD], 13.1 days; 95% CI, -6.70 to -21.11; p = 0.0002; n = 855), intensive care unit length of stay (MD, -10.20 days; 95% CI, -4.66 to -15.74; p = 0.0003; n = 855), and hospital length of stay (MD, -7.39 days; 95% CI, -3.74 to -11.03; p < 0.0001; n = 423). Early tracheostomy was also associated with a decreased incidence of ventilator-associated pneumonia and tracheostomy-related complications (RR, 0.86; 95% CI, 0.75-0.98; p = 0.02; n = 2,043 and RR, 0.64; 95% CI, 0.48-0.84; p = 0.001; n = 812 respectively). The majority of studies ranked as good methodologic quality on the Newcastle Ottawa Scale.ConclusionEarly tracheostomy in patients with acute traumatic SCI may reduce duration of mechanical entilation, length of intensive care unit stay, and length of hospital stay. Current studies highlight the lack of high-level evidence to guide the optimal timing of tracheostomy in acute traumatic SCI. Future research should seek to understand whether early tracheostomy improves patient comfort, decreases duration of sedation, and improves long-term outcomes.Level of evidenceSystematic Review, level III.

Project description:ImportanceIntracranial pressure (ICP) monitoring is a mainstay of therapy for children with traumatic brain injury (TBI), but its overall association with patient outcome is unclear.ObjectiveTo test the hypothesis that ICP monitoring is associated with improved functional survival of children with severe TBI.Design, setting, and participantsA propensity-weighted effectiveness analysis was conducted using 2 linked national databases with data from 30 US children's hospitals from January 1, 2007, to December 31, 2012, on 3084 children with severe TBI. Clinical events including neurosurgical procedures were identified using validated computable phenotypes. Data analysis was conducted from September 1, 2016, to March 1, 2017.ExposurePlacement of an ICP monitor.Main outcomes and measuresA composite of hospital mortality, discharge to hospice, or survival with placement of new tracheostomy and gastrostomy tubes.ResultsOf the 3084 children in the study (1128 girls and 1956 boys; mean [SD] age, 7.03 [5.44] years), 1002 (32.4%) underwent ICP monitoring, with substantial hospital variation (6% to 50% by hospital). Overall, 484 children (15.7%) experienced the primary composite outcome. A propensity approach using matching weights generated good covariate balance between those who did and those who did not undergo ICP monitoring. Using a propensity-weighted logistic regression model clustered by hospital, no statistically significant difference was found in functional survival between monitored and unmonitored patients (odds ratio of poor outcome among those who underwent ICP monitoring, 1.31; 95% CI, 0.99-1.74). In a prespecified secondary analysis, no difference in mortality was found (odds ratio, 1.16; 95% CI, 0.89-1.50). Prespecified subgroup analyses of children younger and older than 2 years of age and among those with unintentional and inflicted (intentional) injuries also showed no difference in outcome with ICP monitoring.Conclusions and relevanceWith the use of linked national data and validated computable phenotypes, no evidence was found of a benefit from ICP monitoring on functional survival of children with severe TBI. Intracranial pressure monitoring is a widely but inconsistently used technology with incompletely demonstrated effectiveness. A large prospective cohort study or randomized trial is needed.

Project description:ImportanceDiversion of cerebrospinal fluid (CSF) has been used for decades as a treatment for children with severe traumatic brain injury (TBI) and is recommended by evidenced-based guidelines. However, these recommendations are based on limited studies.ObjectiveTo determine whether CSF diversion is associated with improved Glasgow Outcome Score-Extended for Pediatrics (GOS-EP) and decreased intracranial pressure (ICP) in children with severe TBI.Design, setting, and participantsThis observational comparative effectiveness study was performed at 51 clinical centers that routinely care for children with severe TBI in 8 countries (US, United Kingdom, Spain, the Netherlands, Australia, New Zealand, South Africa, and India) from February 2014 to September 2017, with follow-up at 6 months after injury (final follow-up, October 22, 2021). Children with severe TBI were included if they had Glasgow Coma Scale (GCS) scores of 8 or lower, had intracranial pressure (ICP) monitor placed on-site, and were aged younger than 18 years. Children were excluded if they were pregnant or an ICP monitor was not placed at the study site. Consecutive children were screened and enrolled, data regarding treatments were collected, and at discharge, consent was obtained for outcomes testing. Propensity matching for pretreatment characteristics was performed to develop matched pairs for primary analysis. Data analyses were completed on April 18, 2022.ExposuresClinical care followed local standards, including the use of CSF diversion (or not), with patients stratified at the time of ICP monitor placement (CSF group vs no CSF group).Main outcomes and measuresThe primary outcome was GOS-EP at 6 months, while ICP was considered as a secondary outcome. CSF vs no CSF was treated as an intention-to-treat analysis, and a sensitivity analysis was performed for children who received delayed CSF diversion.ResultsA total of 1000 children with TBI were enrolled, including 314 who received CSF diversion (mean [SD] age, 7.18 [5.45] years; 208 [66.2%] boys) and 686 who did not (mean [SD] age, 7.79 [5.33] years; 437 [63.7%] boys). The propensity-matched analysis included 98 pairs. In propensity score-matched analyses, there was no difference between groups in GOS-EP (median [IQR] difference, 0 [-3 to 1]; P = .08), but there was a decrease in overall ICP in the CSF group (mean [SD] difference, 3.97 [0.12] mm Hg; P < .001).Conclusions and relevanceIn this comparative effectiveness study, CSF diversion was not associated with improved outcome at 6 months after TBI, but a decrease in ICP was observed. Given the higher quality of evidence generated by this study, current evidence-based guidelines related to CSF diversion should be reconsidered.
