Mode Of Death

Aims and Objectives: Severe traumatic brain injury (sTBI) is the leading cause of death in children. Our aim was to determine the mode of death for children who died with sTBI in a Pediatric Critical Care Unit (PCCU) and evaluate factors associated with mortality.Methods: We performed a retrospective cohort study of all severely injured trauma patients (Injury Severity Score ≥ 12) with sTBI (Glasgow Coma Scale [GCS] ≤ 8 and Maximum Abbreviated Injury Scale ≥ 4) admitted to a Canadian PCCU (2000–2016). We analyzed mode of death, clinical factors, interventions, lab values within 24 h of admission (early) and pre-death (48 h prior to death), and reviewed meeting notes in patients who died in the PCCU.Results: Of 195 included patients with sTBI, 55 (28%) died in the PCCU. Of these, 31 (56%) had a physiologic death (neurologic determination of death or cardiac arrest), while 24 (44%) had withdrawal of life-sustaining therapies (WLST). Median (IQR) times to death were 35.2 (11.8, 86.4) hours in the physiologic group and 79.5 (17.6, 231.3) hours in the WLST group (p = 0.08). The physiologic group had higher partial thromboplastin time (PTT) within 24 h of admission (p = 0.04) and lower albumin prior to death (p = 0.04).Conclusions: Almost half of sTBI deaths in the PCCU were by WLST. There was a trend toward a longer time to death in these patients. We found few early and late (pre-death) factors associated with mode of death, namely higher PTT and lower albumin.

Introductio: Although management of severely injured patients in the Trauma Resuscitation Unit (TRU) follows evidence-based guidelines, algorithms for treatment of the slightly injured are limited. Methods: All trauma patients in a period of eight months in a Level I trauma center were followed. Retrospective analysis was performed only in patients ≥18 years with primary TRU admission, Abbreviated Injury Scale (AIS) ≤ 1, Maximum Abbreviated Injury Scale (MAIS) ≤ 1 and Injury Severity Score (ISS) ≤3 after treatment completion and ≥24 h monitoring in the units. Cochran’s Q-test was used for the statistical evaluation of AIS and ISS changes in units. Results: One hundred and twelve patients were enrolled in the study. Twenty-one patients (18.75%) reported new complaints after treatment completion in the TRU. AIS rose from the Intermediate Care Unit (IMC) to Normal Care Unit (NCU) 6.2% and ISS 6.9%. MAIS did not increase >2, and no intervention was necessary for any patient. No correlation was found between computed tomography (CT) diagnostics in TRU and AIS change. Conclusions: The data suggest that AIS, MAIS and ISS did not increase significantly in patients without a severe injury during inpatient treatment, regardless of the type of CT diagnostics performed in the TRU, suggesting that monitoring of these patients may be unnecessary.

Background Factors associated with delayed injury diagnosis (DID) have been examined, but incompletely researched. Methods We evaluated demographics, mechanism, and measures of mental status and injury severity among 10 years’ worth of adult trauma patients at our center for association with DID in a multivariable regression model. Descriptions of DID injuries were reviewed to highlight characteristics of these injuries. Results We included 13 509 patients, 89 (0.7%) of whom had a recognized DID. In regression analysis, ISS (OR 1.04 per point, 95% CI 1.02-1.06) and number of injuries (OR 1.08 per injury, 95% CI 1.04-1.11) were associated with DID. Operative patients had twice the odds of DID (OR 2.02, 95% CI 1.18-3.44). The most common category of DID was orthopedic extremity injury (22/89). Conclusion DID is associated with injury severity and operative intervention. This suggests that the presence of an injury requiring operation may distract the trauma team from additional injuries.

ABSTRACTObjectivesTo determine the rate of recurrent major trauma (i.e., trauma recidivism) using a provincial population-based trauma registry. We compared outcomes between recidivists and non-recidivists, and assessed factors associated with recidivism and mortality.MethodsReview of all adult (>17 years) major trauma patients in Nova Scotia (2001–2015) using data from the Nova Scotia Trauma Registry. Outcomes of interest were mortality, duration of hospital stay, and in-hospital complications. Multiple regression was used to assess factors associated with recidivism and mortality.ResultsOf 9,365 major trauma patients, 2% (150/9365) were recidivists. Mean age at initial injury was 52 ± 21.5 years; 73% were male. The mortality rate for both recidivists and non-recidivists was 31%. However, after adjusting for potential confounders the likelihood of mortality was over 3 times greater for recidivists compared to non-recidivists (OR 3.67, 95% CI 2.06–6.54). Other factors associated with mortality included age, male gender, penetrating injury, Injury Severity Score, trauma team activation (TTA) and admission to the intensive care unit. The only variables associated with recidivism were age (OR 0.98, 95% CI 0.97–1.00) and TTA (OR 0.59, 95% CI 0.34–0.96).ConclusionsThis is the first provincial investigation of major trauma recidivism in Canada. While recidivism was infrequent (2%), the adjusted odds of mortality were over three times greater for recidivists. Further research is warranted to determine the effectiveness of strategies for reducing rates of major trauma recidivism such as screening and brief intervention in cases of violence or substance abuse.

Abstract Background A threshold Injury Severity Score (ISS) ≥ 16 is common in classifying major trauma (MT), although the Abbreviated Injury Scale (AIS) has been extensively revised over time. The aim of this study was to determine effects of different AIS revisions (1998, 2008 and 2015) on clinical outcome measures. Methods A retrospective observational cohort study including all primary admitted trauma patients was performed (in 2013–2014 AIS98 was used, in 2015–2016 AIS08, AIS08 mapped to AIS15). Different ISS thresholds for MT and their corresponding observed mortality and intensive care (ICU) admission rates were compared between AIS98, AIS08, and AIS15 with Chi-square tests and logistic regression models. Results Thirty-nine thousand three hundred seventeen patients were included. Thresholds ISS08 ≥ 11 and ISS15 ≥ 12 were similar to a threshold ISS98 ≥ 16 for in-hospital mortality (12.9, 12.9, 13.1% respectively) and ICU admission (46.7, 46.2, 46.8% respectively). AIS98 and AIS08 differed significantly for in-hospital mortality in ISS 4–8 (χ2 = 9.926, p = 0.007), ISS 9–11 (χ2 = 13.541, p = 0.001), ISS 25–40 (χ2 = 13.905, p = 0.001) and ISS 41–75 (χ2 = 7.217, p = 0.027). Mortality risks did not differ significantly between AIS08 and AIS15. Conclusion ISS08 ≥ 11 and ISS15 ≥ 12 perform similarly to a threshold ISS98 ≥ 16 for in-hospital mortality and ICU admission. This confirms studies evaluating mapped datasets, and is the first to present an evaluation of implementation of AIS15 on registry datasets. Defining MT using appropriate ISS thresholds is important for quality indicators, comparing datasets and adjusting for injury severity. Level of evidence Prognostic and epidemiological, level III.

Abstract Background: Hypotension is associated with worse outcome in patients with traumatic brain injury (TBI) and maintaining a systolic blood pressure (SBP) ≥110 mmHg is recommended. The aim of this study was to assess the incidence of TBI in patients suffering multi-trauma in remote and mountainous areas; to describe associated factors, treatment and outcome compared to non-hypotensive patients with TBI and patients without TBI; and to evaluate pre-hospital variables to predict admission hypotension.Methods: Data from the International Alpine Trauma Registry including mountain multi-trauma patients (ISS≥16) collected between 2010 and 2019 were analysed. Patients were divided into three groups: 1) TBI with hypotension, 2) TBI without hypotension and 3) no TBI. TBI was defined as Abbreviated Injury Scale (AIS) of the head/neck ≥3 and hypotension as SBP <110 mmHg on hospital arrival.Results: A total of 287 patients were included. Fifty (17%) had TBI and hypotension, 92 (32%) suffered TBI without hypotension and 145 (51%) patients did not have TBI. Patients in group 1 were more severely injured (mean ISS 43.1±17.4 vs 33.3±15.3 vs 26.2±18.1 for group 1 vs 2 vs 3, respectively, p<0.001). Mean SBP on hospital arrival was 83.1±12.9 vs 132.5±19.4 vs 119.4±25.8 mmHg (p<0.001) despite patients in group 1 received more fluids. Patients in group 1 had higher INR, lower haemoglobin and lower base excess (p<0.001). The rate of hypothermia on hospital arrival was different between the groups (p=0.029). Patients in group 1 had the highest mortality (24% vs 10% vs 1%, p<0.001).Conclusion: Multi-trauma in the mountains goes along with severe TBI in almost 50%. One third of patients with TBI is hypotensive on hospital arrival and this is associated with a worse outcome. No single variable or set of variables easily obtainable at scene was able to predict admission hypotension in TBI patients.

Patients with traumatic brain injury (TBI) are often resuscitated with crystalloids in the emergency department (ED) to maintain cerebral perfusion. The purpose of this study was to evaluate whether crystalloid resuscitation volume impacts mortality in TBI patients. This was a retrospective study of trauma patients with head abbreviated injury scale score ≥2, who received crystalloids during ED resuscitation between 2004 and 2013. Clinical characteristics and volume of crystalloids received in the ED were collected. Patients who received <2 L of crystalloids were categorized as low volume (LOW), whereas those who received ≥2 L were considered high volume (HIGH). Mortality and outcomes were compared. Multivariable regression analysis was used to determine the odds of mortality while controlling for confounders. Over 10 years, 875 patients met inclusion criteria. Overall mortality was 12.5 per cent. Seven hundred and forty-two (85%) were in the LOW cohort and 133 (15%) in the HIGH cohort. Gender and age were similar between the groups. The HIGH cohort had lower admission systolic blood pressure (128 vs 138 mm Hg, P = 0.001), lower Glasgow coma scale score (10 vs 12, P < 0.001), higher head abbreviated injury scale (3.8 vs 3.3, P < 0.001), and higher injury severity score (25 vs 18, P < 0.001). The LOW group had a lower unadjusted mortality (10 vs 26%, P < 0.001). Multivariable analysis adjusting for confounders demonstrated that those resuscitated with ≥2 L of crystalloids had increased odds of mortality (adjusted odds ratio 2.25, P = 0.005). Higher volume crystalloid resuscitation after TBI is associated with increased mortality, thus limited resuscitation for TBI patients may be indicated.

Severe traumatic brain injury (TBI) is associated with increased risk for early clinical and sub-clinical seizures. The use of continuous electroencephalography (cEEG) monitoring after TBI allows for identification and treatment of seizures that may otherwise occur undetected. Benefits of “routine” cEEG after TBI remain controversial. We examined the rate of subclinical seizures identified by cEEG in TBI patients admitted to a Level I trauma center. We analyzed a cohort of trauma patients with moderate to severe TBI (head Abbreviated Injury Score ≥3) who received cEEG within seven days of admission between October 2011 and May 2015. Demographics, clinical data, injury severity, and costs were recorded. Clinical characteristics were compared between those with and without seizures as identified by cEEG. A total of 106 TBI patients with moderate to severe TBI received a cEEG during the study period. Most were male (74%) with a mean age of 55 years. Subclinical seizures were identified by cEEG in only 3.8 per cent of patients. Ninety-three per cent were on antiseizure prophylaxis at the time of cEEG. Patients who had subclinical seizures were significantly older than their counterparts (80 vs 54 years, P = 0.03) with a higher mean head Abbreviated Injury Score (5.0 vs 4.0, P = 0.01). Mortality and intensive care unit stay were similar in both groups. Of all TBI patients who were monitored with cEEG, seizures were identified in only 3.8 per cent. Seizures were more likely to occur in older patients with severe head injury. Given the high cost of routine cEEG and the low incidence of subclinical seizures, we recommend cEEG monitoring only when clinically indicated.

The geriatric population is growing and trauma providers are often tasked with caring for injuries in the elderly. There is limited information regarding injury patterns in geriatric trauma patients stratified by mechanism of injury. This study intends to investigate the comorbidities, mechanisms, injury patterns, and outcomes in geriatric blunt trauma patients. A retrospective study of the 2012 National Trauma Databank was performed. Adult blunt trauma patients were identified; geriatric (>/=65) patients were compared with younger (<65) patients regarding admission demographics and vital signs, mechanism and severity of injury, and comorbidities. The primary outcome was injuries sustained and secondary outcomes included mortality, length of stay in the intensive care unit and hospital, and ventilator days. There were 589,830 blunt trauma patients who met the inclusion criteria, including 183,209 (31%) geriatric and 406,621 (69%) nongeriatric patients. Falls were more common in geriatric patients (79 vs 29%, P < 0.0001). Geriatric patients less often had an Injury Severity Score >/=16 (18 vs 20%, P < 0.0001) but more often a head Abbreviated Injury Scale >/=3 (24 vs 18%, P < 0.0001) and lower extremity Abbreviated Injury Scale >/=3 (24% vs 8%, P < 0.0001). After logistic regression older age was an independent risk factor for mortality for the overall population and across all mechanisms. Falls are the most common mechanism for geriatric trauma patients. Geriatric patients overall present with a lower Injury Severity Score, but more often sustain severe injuries to the head and lower extremities. Injury patterns vary significantly between older and younger patients when stratified by mechanism. Mortality is significantly higher for geriatric trauma patients and older age is independently associated with mortality across all mechanisms.

Objective: To describe clinical factors associated with mortality and causes of death in tracheostomy-dependent (TD) children.Methods: A retrospective study of patients with a new or established tracheostomy requiring hospitalization at a large tertiary children's hospital between 2009 and 2015 was conducted. Patient groups were developed based on indication for tracheostomy: pulmonary, anatomic/airway obstruction, and neurologic causes. The outcome measures were overall mortality rate, mortality risk factors, and causes of death.Results: A total of 187 patients were identified as TD with complete data available for 164 patients. Primary indications for tracheostomy included pulmonary (40%), anatomic/airway obstruction (36%), and neurologic (24%). The median age at tracheostomy and duration of follow up were 6.6 months (IQR 3.5–19.5 months) and 23.8 months (IQR 9.9–46.7 months), respectively. Overall, 45 (27%) patients died during the study period and the median time to death following tracheostomy was 9.8 months (IQR 6.1–29.7 months). Overall survival at 1- and 5-years following tracheostomy was 83% (95% CI: 76–88%) and 68% (95% CI: 57–76%), respectively. There was no significant difference in mortality based on indication for tracheostomy (p = 0.35), however pulmonary indication for tracheostomy was associated with a shorter time to death (HR: 1.9; 95% CI: 1.04–3.4; p = 0.04). Among the co-morbid medical conditions, children with seizure disorder had higher mortality (p = 0.04).Conclusion: In this study, TD children had a high mortality rate with no significant difference in mortality based on indication for tracheostomy. Pulmonary indication for tracheostomy was associated with a shorter time to death and neurologic indication was associated with lower decannulation rates.
