Effect on outcome of early intensive management of geriatric trauma patients

The Magic Number 63 - Redefining the Geriatric Age for Massive Transfusion in Trauma

INTRODUCTION

The arbitrary geriatric age cutoff of 65 may not accurately define older adults at higher risk of mortality following massive transfusion (MT). We sought to redefine a new geriatric age threshold for MT and understand its association with outcomes.

MATERIAL AND METHODS

The 2013-2018 Trauma Quality Improvement Program database was queried for all adults who received ≥10 units of packed red blood cells (pRBCs) within 24 h of admission. A bootstrap analysis using multiple logistic regression established transfusion futility thresholds (TTs), where additional pRBCs no longer improved mortality for various age cutoffs. The age cutoff at which the TT for those relatively older and relatively younger was statistically significant was used to define the new "geriatric" age for MT. Outcomes were then compared between the newly defined geriatric and nongeriatric patients.

RESULTS

The difference in TT first became significant when the age cutoff was 63 y. The TT for patients aged ≥63 y (new geriatric, n = 2870) versus <63 y (nongeriatric, n = 17,302) was 34 and 40 units of pRBCs, respectively (P = 0.04). Although geriatric patients had a higher Glasgow coma scale score (9 versus 6, P < 0.01) and lower abbreviated injury score-abdomen (3 versus 4, P < 0.01) than the nongeriatric, they suffered higher overall mortality (62% versus 45%, P < 0.01). A lower percentage of geriatric patients were discharged to home (7% versus 35%, P < 0.01).

CONCLUSIONS

The new geriatric age for MT is 63 y, with a TT of 34 units. Despite suffering less severe injuries, physiologically "geriatric" patients have worse outcomes following MT.

Major trauma patients and their outcomes - A retrospective observational study of critical care trauma admissions to a trauma unit with special services

INTRODUCTION

International data describes a changing pattern to trauma over the last decade, with an increasingly comorbid population presenting challenges to trauma management and resources. In Ireland, resource provision and management of trauma is being transformed to deliver a trauma network, in line with international best practice. Our hospital plays a crucial role within this network and is designated a Trauma Unit with Specialist Services (TUSS) to distinguish it from standard trauma units.

METHODS

This study aims to describe the characteristics of patients and injuries and assess trends in mortality rates. It is a retrospective observational study of adult ICU trauma admissions from August 2010 to July 2021. Primary outcome was all-cause mortality at 30-days, 90-days, and 1 year. Secondary outcomes included length of stay, disposition, and complications. Patients were categorised by age, injury severity score (ISS), and mechanism of injury.

RESULTS

In all, 709 patients were identified for final analysis. Annual admissions doubled since 2010/11, with a trough of 41 admissions, increasing to peak at 95 admissions in 2017/18. Blunt trauma accounted for 97.6% of cases. Falls <2 m (45.4%) and RTAs (29.2%) were the main mechanisms of injury. Polytrauma comprised 41.9% of admissions. Traumatic brain injury accounted for 30.2% of cases; 18.8% of these patients were transferred to a neurosurgical centre. The majority of patients, 58.1%, were severely injured (ISS ≥ 16). Patients ≥ 65 years of age accounted for 45.7% of admissions, with falls <2 m their primary mechanism of injury. The primary outcome of all-cause mortality reduced with an absolute risk reduction (ARR) of 8.0% (95% CI: -8.37%, 24.36%), 12.9% (95% CI: -4.19%, 29.94%) and 8.2% (95% CI: -9.64%, 26.09%) for 30-day, 90-day and 1-year respectively. Regression analysis demonstrated a significant reduction in mortality for 30-days and 90-days post presentation to hospital (P-values of 0.018, 0.033 and 0.152 for 30-day, 90-day and 1-year respectively).

CONCLUSION

The burden of major trauma in our hospital is considerable and increasing over time. Substantial changes in demographics, injury mechanism and mortality were seen, with outcomes improving over time. This is consistent with international data where trauma systems have been adopted.

Characteristics and demography of low energy fall injuries in patients > 60 years of age: a population-based analysis over a decade with focus on undertriage

BACKGROUND

An increasing group of elderly patients is admitted after low energy falls. Several studies have shown that this patient group tends to be severely injured and is often undertriaged.

METHODS

Patients > 60 years with low energy fall (< 1 m) as mechanism of injury were identified from the Stavanger University Hospital trauma registry. The study period was between 01.01.11 and 31.12.20. Patient and injury variables as well as clinical outcome were described. Undertriage was defined as patients with a major trauma, i.e., Injury Severity Score (ISS) > 15, without trauma team activation. Statistical analysis was performed using the Chi-squared test for categorical variables and the Mann-Whitney U test for continuous variables.

RESULTS

Over the 10-year study period, 388 patients > 60 years with low energy fall as mechanism of injury were identified. Median age was 78 years (IQR 68-86), and 53% were males. The location of major injury was head injury in 41% of the patients, lower extremities in 19%, and thoracic injuries in 10%. Thirty-day mortality was 13%. Fifty percent were discharged to home, 31% to nursing home, 9% in hospital mortality, and the remaining 10% were transferred to other hospitals or rehabilitation facilities. Ninety patients had major trauma, and the undertriage was 48% (95% confidence interval, 38 to 58%).

CONCLUSIONS

Patients aged > 60 years with low energy falls are dominated by head injuries, and the 30-day mortality is 13%. Patients with major trauma are undertriaged in half the cases mandating increased awareness of this patient group.

The 2023 WSES guidelines on the management of trauma in elderly and frail patients

BACKGROUND

The trauma mortality rate is higher in the elderly compared with younger patients. Ageing is associated with physiological changes in multiple systems and correlated with frailty. Frailty is a risk factor for mortality in elderly trauma patients. We aim to provide evidence-based guidelines for the management of geriatric trauma patients to improve it and reduce futile procedures.

METHODS

Six working groups of expert acute care and trauma surgeons reviewed extensively the literature according to the topic and the PICO question assigned. Statements and recommendations were assessed according to the GRADE methodology and approved by a consensus of experts in the field at the 10th international congress of the WSES in 2023.

RESULTS

The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage, including drug history, frailty assessment, nutritional status, and early activation of trauma protocol to improve outcomes. Acute trauma pain in the elderly has to be managed in a multimodal analgesic approach, to avoid side effects of opioid use. Antibiotic prophylaxis is recommended in penetrating (abdominal, thoracic) trauma, in severely burned and in open fractures elderly patients to decrease septic complications. Antibiotics are not recommended in blunt trauma in the absence of signs of sepsis and septic shock. Venous thromboembolism prophylaxis with LMWH or UFH should be administrated as soon as possible in high and moderate-risk elderly trauma patients according to the renal function, weight of the patient and bleeding risk. A palliative care team should be involved as soon as possible to discuss the end of life in a multidisciplinary approach considering the patient's directives, family feelings and representatives' desires, and all decisions should be shared.

CONCLUSIONS

The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage based on assessing frailty and early activation of trauma protocol to improve outcomes. Geriatric Intensive Care Units are needed to care for elderly and frail trauma patients in a multidisciplinary approach to decrease mortality and improve outcomes.

Management of the Geriatric Trauma Patient

With a rapidly aging worldwide population, the care of geriatric trauma patients will be at the forefront of every career in Trauma and Acute Care Surgery. The unique intersection of advanced age, comorbidities, frailty, and physiologic changes presents a challenge in the care of elderly injured patients. It is well established that increasing age is associated with higher mortality and worse outcomes after injury, but it is also clear that there is room for improvement in the management of this special patient population.

The Effect of 2019 Coronavirus Stay-at-Home Order on Geriatric Trauma Patients in Southern California

BACKGROUND

California issued stay-at-home (SAH) orders to mitigate COVID-19 spread. Previous studies demonstrated a shift in mechanisms of injuries (MOIs) and decreased length of stay (LOS) for the general trauma population after SAH orders. This study aimed to evaluate the effects of SAH orders on geriatric trauma patients (GTPs), hypothesizing decreased motor vehicle collisions (MVCs) and LOS.

METHODS

A post-hoc analysis of GTPs (≥65 years old) from 11 level-I/II trauma centers was performed, stratifying patients into 3 groups: before SAH (1/1/2020-3/18/2020) (PRE), after SAH (3/19/2020-6/30/2020) (POST), and a historical control (3/19/2019-6/30/2019) (CONTROL). Bivariate comparisons were performed.

RESULTS

5486 GTPs were included (PRE-1756; POST-1706; CONTROL-2024). POST had a decreased rate of MVCs (7.6% vs 10.6%, P = .001; vs 11.9%, P < .001) and pedestrian struck (3.4% vs 5.8%, P = .001; vs 5.2%, P = .006) compared with PRE and CONTROL. Other mechanisms of injury, LOS, mortality, and operations performed were similar between cohorts. However, POST had a lower rate of discharge to skilled nursing facility (SNF) (20% vs 24.5%, P = .001; and 20% vs 24.4%, P = .001).

CONCLUSION

This retrospective multicenter study demonstrated lower rates of MVCs and pedestrian struck for GTPs, which may be explained by decreased population movement as a result of SAH orders. Contrary to previous studies on the generalized adult population, no differences in other MOIs and LOS were observed after SAH orders. However, there was a lower rate of discharge to SNF, which may be related to a lack of resources due to the COVID-19 pandemic, and thus potentially negatively impacted recovery of GTPs.Keywords.

Evaluating the impact of pre-hospital trauma team activation criteria

BACKGROUND

Little evidence exists studying the benefits of pre-hospital trauma team activation. Our study measured the impact of pre-hospital trauma team activation on 24-h survival. Our secondary objectives assessed the effects of pre-hospital trauma team activation on time to emergency procedure, computed tomography, blood transfusion, and critical administration threshold, as well as emergency department length of stay.

METHODS

We conducted a 40-month health records review on all trauma team activations at The Ottawa Hospital, a Level 1 Trauma Center. Outcomes were compared between pre-hospital and in-hospital trauma team activations. We used logistic and linear regression models to assess outcomes, while controlling for injury severity score, age, systolic blood pressure, and anti-coagulation use. A P value < 0.05 was considered statistically significant. A sensitivity analysis was also used to validate the primary outcome results.

RESULTS

Of the 1013 trauma team activations occurring during the study period, 762 patients were included. The mean age (41.3 vs. 43.8) and percentage of males (79.4% vs. 77.5%) for pre-hospital activations were similar to their counterparts. Pre-hospital activations did not have a statistically significant effect on 24-h mortality (14.4% vs. 4.5%; P = 0.30). However, pre-hospital activations did demonstrate a statistically significant reduction in time (minutes) to emergency procedure (18.0 vs. 27.0; P < 0.001), computed tomography (37.0 vs 42.0; P = 0.009), and blood transfusion (14.0 vs. 28.0; P < 0.001), as well as emergency department length of stay (101.0 vs. 171.0; P < 0.001).

CONCLUSION

When controlling for key covariates, pre-hospital trauma team activation did not have a significant effect on 24-h mortality, but did result in a significant reduction in time to emergency procedure, computed tomography, and blood transfusion, as well as emergency department length of stay. Our study demonstrates that pre-hospital trauma team activation can expedite patient intervention and disposition.

All about the Benjamins: Efficacy of a modified triage protocol for trauma activation in geriatric patients

BACKGROUND

The geriatric triage protocol at the study institution was modified from SBP <90 mmHg to SBP <110 mmHg and then to SBP <100 mmHg. The purpose of this study is to evaluate the impact of adjusting geriatric triage protocols on patient outcomes.

METHODS

A single-center retrospective review was conducted on trauma patients 65 years or older. Three study periods with different geriatric specific trauma team activation (TTA) protocols (Group 1-SBP<90 mmHg; Group 2-SBP<110 mmHg; Group 3-SBP<100 mmHg) were compared.

RESULTS

2016 patients were included. There were no differences in mortality rates or need for trauma intervention (NFTI) rates among the three groups. The SBP <100 mmHg and SBP <110 mmHg groups had similar under-triage rates. The NFTI over-triage rate in the SBP <100 mmHg group was lower than the SBP <110 mmHg group.

CONCLUSION

Using SBP <100 mmHg threshold for TTA criteria in geriatric trauma patients improves over-triage without leading to under-triage.

Does mortality after trauma team activation peak at shift change?

BACKGROUND

Prior institutional data have demonstrated trauma mortality to be highest between 06:00-07:59 at our center, which is also when providers change shifts (07:00-07:30). The objective was definition of patient, provider, and systems variables associated with trauma mortality at shift change among patients arriving as trauma team activations (TTA).

METHODS

All TTA patients at our ACS-verified Level I trauma center were included (01/2008-07/2019), excluding those with undocumented arrival time. Study groups were defined by arrival time: shift change (SC) (06:00-07:59) vs. non-shift change (NSC) (all other times). Univariable/multivariable analyses compared key variables. Propensity score analysis compared outcomes after matching.

RESULTS

After exclusions, 6020 patients remained: 229 (4%) SC and 5791 (96%) NSC. SC mortality was 25% vs. 16% during NSC (p < 0.001). More SC patients arrived with SBP <90 (19% vs. 11%, p < 0.001) or GCS <9 (35% vs. 24%, p < 0.001). ISS was higher during SC (43[32-50] vs. 34[27-50], p < 0.001). Time to CT scan (36[23-66] vs. 38[23-61] minutes, p = 0.638) and emergent surgery (94[35-141] vs. 63[34-107] minutes, p = 0.071) were comparable. Older age (p < 0.001), SBP <90 (p < 0.001), GCS <9 (p < 0.001), need for emergent operative intervention (p = 0.044), and higher ISS (p < 0.001) were independently associated with mortality. After propensity score matching, mortality was no different between SC and NSC (p = 0.764).

CONCLUSIONS

Early morning is a low-volume, high-mortality time for TTAs. Increased mortality at shift change was independently associated with patient/injury factors but not provider/systems factors. Ensuring ample clinical resource allocation during this high acuity time may be prudent to streamline patient care at shift change.

Comparing Comorbidity Polypharmacy Score and Charlson Comorbidity Index in predicting outcomes in older trauma patients

BACKGROUND

The Charlson Comorbidity Index (CCI) and Comorbidity Polypharmacy Score (CPS) may potentially risk-stratify older trauma patients more accurately than traditional trauma severity scores. We aim to evaluate if CCI or CPS are better predictors of mortality and discharge venue in such patients.

METHODS

We conducted a retrospective study using registry data from two tertiary trauma centres. Patients aged 65 years and above who presented to the emergency departments (EDs) between January 2011 and December 2015 with traumatic injuries were included. Charts were reviewed for demographics, injury mechanism and severity, discharge outcomes, and types of comorbidities and medications used. Primary outcome was overall mortality; secondary outcomes included ED disposition and hospital discharge venue. Discriminatory power of the score(s) were compared using area under the receiver operating characteristic (AUROC) curve.

RESULTS

There were 2,750 patients, with overall female predominance (56.7%, 1,560/2,750) and median age of 78 years (interquartile range [IQR] 72 to 84 years). Median CCI score was 1 (IQR 0 to 2) and median CPS was 8 (IQR 4 to 12). Overall mortality was 9.4% (259/2,750). Every 1-point increase in CCI score resulted in increased odds of death by 16% (adjusted odds ratio 1.16, 95% confidence interval 1.07 to 1.26, p<0.001). Addition of CCI to the Injury Severity Score (ISS) increased the discriminatory power for mortality (AUROC for ISS = 0.832; AUROC for ISS with CCI = 0.843). Every 1-point increase in CCI was significantly associated with decreased odds of admission to a rehab facility by 8%. CPS did not predict mortality and discharge venue.

CONCLUSION

CCI, but not CPS, was a predictor of mortality. A higher CCI was associated with decreased odds of discharge to a subacute facility, likely related to underlying rehabilitation potential. Further studies should be undertaken to explore an integrated scoring system that considers injury severity, comorbidities, and polypharmacy.

Configurations and outcomes of acute hospital care for frail and older patients with moderate to major trauma: a systematic review

OBJECTIVE

To systematically review research on acute hospital care for frail or older adults experiencing moderate to major trauma.

SETTING

Electronic databases (Medline, Embase, ASSIA, CINAHL Plus, SCOPUS, PsycINFO, EconLit, The Cochrane Library) were searched using index and key words, and reference lists and related articles hand-searched.

INCLUDED ARTICLES

Peer-reviewed articles of any study design, published in English, 1999-2020 inclusive, referring to models of care for frail and/or older people in the acute hospital phase of care following traumatic injury defined as either moderate or major (mean or median Injury Severity Score ≥9). Excluded articles reported no empirical findings, were abstracts or literature reviews, or referred to frailty screening alone.

METHODS

Screening abstracts and full text, and completing data extractions and quality assessments using QualSyst was a blinded parallel process. A narrative synthesis, grouped by intervention type, was undertaken.

OUTCOME MEASURES

Any outcomes reported for patients, staff or care system.

RESULTS

17 603 references were identified and 518 read in full; 22 were included-frailty and major trauma (n=0), frailty and moderate trauma (n=1), older people and major trauma (n=8), moderate or major trauma (n=7) 0r moderate trauma (n=6) . Studies were observational, heterogeneous in intervention and with variable methodological quality.Specific attention given to the care of older and/or frail people with moderate to major trauma in the North American context resulted in improvements to in-hospital processes and clinical outcomes, but highlights a relative paucity of evidence, particularly in relation to the first 48 hours post-injury.

CONCLUSIONS

This systematic review supports the need for, and further research into an intervention to address the care of frail and/or older patients with major trauma, and for the careful definition of age and frailty in relation to moderate or major trauma.

Emergency physician and nurse discretion accurately triage high-risk trauma patients

PURPOSE

Prehospital trauma team activation (TTA) criteria allow for early identification of severely injured trauma patients. Although most TTA criteria are objective, one TTA criterion is subjective: emergency provider discretion. The study objective was to define the ability of emergency department physician and nurse discretion to accurately perform prehospital triage of high risk trauma patients.

METHODS

All highest level TTAs arriving to our American College of Surgeons (ACS)-verified Level 1 trauma center (06/2015-08/2020) were included. Exclusions were undocumented prehospital vitals or discharge disposition. At our institution, TTAs are triggered for standard ACS TTA criteria and age > 70 with traumatic mechanism other than ground level fall. Patients meeting ≥ 1 criterion apart from "Emergency Provider Discretion" were defined as Standard TTAs and patients meeting only "Emergency Provider Discretion" were defined as Discretion TTAs. Univariable/multivariable analyses compared injury data and outcomes.

RESULTS

4540 patients met inclusion/exclusion criteria: 3330 (73%) Standard TTAs and 1210 (27%) Discretion TTAs. Discretion TTAs were younger (34 vs. 37 years, p < 0.001) and more frequently injured by penetrating trauma (38% vs. 33%, p = 0.008), particularly stab wounds (64% vs. 29%). Overtriage rates were comparable after Discretion vs. Standard TTAs (33% vs. 31%, p = 0.141). Blood transfusion < 4 h (31% vs. 32%, p = 0.503) and ICU admission ≥ 3 days (25% vs. 27%, p = 0.058) were comparable between groups. Discretion TTA was independently associated with increased need for emergent surgery (OR 1.316, p = 0.005).

CONCLUSIONS

Emergency provider discretion accurately identifies major trauma, with comparable rates of overtriage as standard TTA criteria. Discretion TTAs were as likely as Standard TTAs to require early blood transfusion and prolonged ICU stay. After controlling for confounders, Discretion TTAs were significantly more likely to require emergent surgical intervention. Emergency provider discretion should be recognized as a valid method of identifying major trauma patients at high risk of need for intervention.

Blunt traumatic aortic injury in the elderly population

OBJECTIVE

Blunt thoracic aortic injury (BTAI) is a major cause of morbidity and mortality in trauma patients. Although outcomes for BTAI have been described in younger patient populations, elderly patients may present with different patterns of injury and have unique factors contributing to morbidity and mortality. This study aims to describe patterns of presentation and management in elderly patients presenting with BTAI using a nationwide database.

METHODS

Patients aged 65 years and older with BTAI from 2007 through 2016 were identified from the American College of Surgeons Trauma Quality Improvement Program database. Baseline demographics, initial physiologic variables, and clinical outcomes were extracted from the database. Our primary outcome was in-hospital mortality. An adjusted Poisson generalized regression model was used to compare rates of mortality for thoracic endovascular aortic repair (TEVAR), open repair, and nonoperative management.

RESULTS

During the study period, 1322 patients aged 65 years and over sustained BTAI and survived past triage. Mean age was 74.7 years, and 60% were male. There were low incidence rates of concomitant major head (9.4%), spine (3.1%), and abdominal (5.7%) injuries. Three hundred fifty (26.5%) underwent TEVAR, 58 (4.4%) open repair, and 914 (69.1%) were managed nonoperatively. Utilization of TEVAR increased from 13.1% to 32.7% from 2007 to 2015, with subsequent decline to 19.9% in 2016 in favor of nonoperative management. Age, gender, and mean Injury Severity Scores (ISS) did not significantly differ by management. In-hospital mortality for the entire cohort was 37.9%. In an adjusted Poisson generalized regression model using inverse probability of treatment weighting controlling for age, race, gender, ISS, and hypotension, TEVAR was associated with the lowest mortality rate (1.31 deaths/100 person-years; 95% confidence interval [CI], 1.17-1.46) compared with open repair (2.53; 95% CI, 2.32-2.75; P < .001) and nonoperative management (3.91; 95% CI, 3.60-4.25; P < .001). There was a higher incidence of acute kidney injury, acute respiratory distress syndrome, and surgical site infection in the TEVAR group.

CONCLUSIONS

This study describes the management of and outcomes for BTAI in the elderly population. The majority of patients did not undergo operative repair, which was associated with a higher risk of in-hospital mortality. In an adjusted analysis, TEVAR was associated with the lowest mortality rate, compared with open repair and nonoperative management.

All elderly are fragile, but some are more fragile than others: an epidemiological study from one of the busiest trauma centers in Italy

As the older population increases, the number of elderly accessing the emergency department following a trauma increases accordingly. High-level trauma enters together with the identification of predictive parameters for poor outcome and mortality, may result in a death rate improvement of up to 30% in this group of patients. This study analyzes the epidemiology of major trauma admissions at Niguarda Trauma Center in Milan, Italy, focusing on the geriatric population and aiming to discriminate the trauma outcomes in the range of population between 65 and 75 years old (Senior Adult) and to compare it with the outcomes among people over 75 years old (Elderly). The variables analyzed included mortality, mechanism of injury, body district injured, Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), Geriatric Trauma Score (GTO), and outcome. Head trauma remains the main cause of mortality with falls and road accidents being the most common mechanism of injury. Frailty and associated use of anticoagulant and antiplatelet therapy increased the risk of death by 42%. The subdivision of the elder patients into two groups (65-75 and > 75) showed a difference in the probability of death and effective mortality rate.

Care of the older trauma patient following low-energy transfer trauma-highlighting a research void

BACKGROUND

in high-income countries trauma patients are becoming older, more likely to have comorbidities, and are being injured by low-energy mechanisms. This systematic review investigates the association between higher-level trauma centre care and outcomes of adult patients who were admitted to hospital due to injuries sustained following low-energy trauma.

METHODS

a systematic review was conducted in January 2021. Studies were eligible if they reported outcomes in adults admitted to hospital due to low-energy trauma. In the presence of study heterogeneity, a narrative synthesis was pre-specified.

RESULTS

three studies were included from 2,898 unique records. The studies' risk of bias was moderate-to-serious. All studies compared outcomes in trauma centres verified by the American College of Surgeons in the USA. The mean/median ages of patients in the studies were 73.4, 74.5 and 80 years. The studies reported divergent results. One demonstrated improved outcomes in level 3 or 4 trauma centres (Observed: Expected Mortality 0.973, 95% CI: 0.971-0.975), one demonstrated improved outcomes in level 1 trauma centres (Adjusted Odds Ratio 0.71, 95% CI: 0.56-0.91), and one demonstrated no difference between level 1 or 2 and level 3 or 4 trauma centre care (adjusted odds ratio 0.91, 95% CI: 0.80-1.04).

CONCLUSIONS

the few relevant studies identified provided discordant evidence for the value of major trauma centre care following low-energy trauma. The main implication of this review is the paucity of high-quality research into the optimum care of patients injured in low-energy trauma. Further studies into triage, interventions and research methodology are required.

Injury profiles and clinical management of older patients with major trauma

OBJECTIVES

This study aimed to characterise the most common injury profiles and interventions in older major trauma patients, and how they change with age.

METHODS

This is a retrospective review of interventions, injury profiles and outcomes of major trauma patients aged 65 years and older from 2007 to 2018, using data from the Victorian State Trauma Registry. A latent class analysis (LCA) was used to identify homogenous injury groups.

RESULTS

The LCA identified five injury profiles: isolated head injury; chest/upper limb injuries; multi-trauma; isolated spine; and head/chest/upper limb. Among 10,001 patients, 50% had an isolated head injury, and 83% of patients received definitive treatment at a major trauma centre. 50% of patients received a surgical or non-surgical intervention, and 36% underwent surgery. These proportions declined with increasing age.

CONCLUSIONS

Older patients with major trauma are a heterogeneous group, whose mechanisms and patterns of injury, and clinical management change with increasing age.

Elderly trauma mortality in a resource-limited setting: A benchmark for process improvement

INTRODUCTION

As life expectancy improves globally, the burden of elderly trauma continues to increase. Sub-Saharan Africa is projected to have the most rapid growth in its elderly demographic. Consequently, we sought to examine the trends in characteristics and outcomes of elderly trauma in a tertiary care hospital in Malawi.

METHODS

We performed a retrospective analysis of adult patients in the trauma registry at Kamuzu Central Hospital (KCH) in Lilongwe, Malawi from 2011-2017. Patients were categorized into elderly (≥ 65 years) and non-elderly (18-64 years). Bivariate analysis compared the characteristics and outcomes of elderly vs. non-elderly patients. The elderly population was then examined over the study period. Poisson regression modeling was used to determine the risk of mortality among elderly patients over time.

RESULTS

Of 63,699 adult trauma patients, 1,925 (3.0%) were aged ≥ 65 years. Among the elderly, the most common mechanism of injury was falls (n = 725 [37.7%]) whereas vehicle or bike collisions were more common in the non-elderly (n = 15,967 [25.9%]). Fractures and dislocations were more prevalent in the elderly (n = 808 [42.0%] vs. 9,133 [14.8%], p < 0.001). In-hospital crude mortality for the elderly was double the non-elderly group (4.8% vs. 2.4%, p < 0.001). Elderly transfers, surgeries, and length of stay significantly increased over the study period but mortality remained relatively unchanged. When adjusted for injury severity and transfer status, there was no significant difference in risk of in-hospital mortality over time.

CONCLUSION

At KCH, the proportion of elderly trauma patients is slowly increasing. Although healthcare resource utilization has increased over time, the overall trend in mortality has not improved. As the quality of care for the most vulnerable populations is a benchmark for the success of a trauma program, further work is needed to improve the trend in outcomes of the elderly trauma population in Malawi.

Evaluation of elderly specific pre-hospital trauma triage criteria: a systematic review

BACKGROUND

Pre-hospital identification of major trauma in elderly patients is key for delivery of optimal care, however triage of this group is challenging. Elderly-specific triage criteria may be valuable. This systematic review aimed to summarise the published pre-hospital elderly-specific trauma triage tools and evaluate their sensitivity and specificity and associated clinical outcomes.

METHODS

MEDLINE and EMBASE databases were searched using predetermined criteria (PROSPERO: CRD42019140879). Two authors independently assessed search results, performed data extraction, risk of bias and quality assessments following the Grading of Recommendations, Assessment, Development and Evaluation system.

RESULTS

801 articles were screened and 11 studies met eligibility criteria, including 1,332,300 patients from exclusively USA populations. There were eight unique elderly-specific triage criteria reported. Most studies retrospectively applied criteria to trauma databases, with few reporting real-world application. The Ohio Geriatric Triage Criteria was reported in three studies. Age cut-off ranged from 55 to 70 years with ≥ 65 most frequently reported. All reported existing adult criteria with modified physiological parameters using higher thresholds for systolic blood pressure and Glasgow coma scale, although the values used varied. Three criteria added co-morbidity or anti-coagulant/anti-platelet use considerations. Modifications to anatomical or mechanism of injury factors were used by only one triage criteria. Criteria sensitivity ranged from 44 to 93%, with a median of 86.3%, whilst specificity was generally poor (median 54%). Scant real-world data showed an increase in patients meeting triage criteria, but minimal changes to patient transport destination and mortality. All studies were at risk of bias and assessed of "very low" or "low" quality.

CONCLUSIONS

There are several published elderly-specific pre-hospital trauma triage tools in clinical practice, all developed and employed in the USA. Consensus exists for higher thresholds for physiological parameters, however there was variability in age-cut offs, triage criteria content, and tool sensitivity and specificity. Although sensitivity was improved over corresponding 'adult' criteria, specificity remained poor. There is a paucity of published real-world data examining the effect on patient care and clinical outcomes of elderly-specific triage criteria. There is uncertainty over the optimal elderly triage tool and further study is required to better inform practice and improve patient outcomes.

Emergency Department as the Entry Point to Inpatient Care: A Nationwide, Population-Based Study in South Korea, 2016-2018

(1) Background: The emergency department provides lifesaving treatment and has become an entry point to hospital admission. The purpose of our study was to describe the characteristics and outcomes of patients who were admitted through the emergency department to the intensive care unit or general ward. (2) Methods: We performed a retrospective, cross-sectional, descriptive analysis using the National Emergency Department Information System, analyzing patient data including disease category, diagnosis, and mortality from 1 January 2016, to 31 December 2018. (3) Results: During the study period, about 13.6% were admitted through the emergency department. Of these, the overall in-hospital mortality was 4.6%. The frequent disease class for the intensive care unit admissions was the cardiovascular system, and the classes for the general ward admissions were as follows: injury and toxicology, digestive system, and respiratory system. Cardiovascular system-related emergencies were the predominant cause of death among patients admitted to the intensive care unit; however, oncologic complications were the leading cause of death in the general ward. (4) Conclusions: Emergency departments are incrementally utilized as the entry point for hospital admission. Health care providers need to understand emergency department admission epidemiology and prepare for managing patients with certain common diagnoses.

Isolated rib cage fractures in the elderly: Do all patients belong to the intensive care unit? A retrospective nationwide analysis

BACKGROUND

Western Trauma Association guidelines recommend admitting patients 65 years or older with two or more rib fractures diagnosed by chest radiograph to the intensive care unit (ICU). Increased use of computed tomography has led to identification of less severe, "occult" rib fractures. We aimed to evaluate current national trends in disposition of older patients with isolated rib cage fractures and to identify characteristics of patients initially admitted to the ward who failed ward management.

METHODS

A retrospective cohort study of patients 65 years or older with isolated two or more blunt rib cage fractures using the 2010 to 2016 American College of Surgeons Trauma Quality Improvement Program database was performed. Ward failure was defined as patients initially admitted to the ward with subsequent need for unplanned ICU admission or intubation. Multivariable analyses were derived to study the independent predictors of failure of ward management. Propensity score matching sub-analysis was used to assess outcomes in patients admitted to the ward versus ICU.

RESULTS

There were 5,021 patients included in the analysis. Of these patients, 1,406 (28.0%) were admitted to the ICU. On multivariable analysis, age was an independent predictor of ICU admission. Of the 3,577 patients admitted directly to the ward, 38 (1.1%) patients required unplanned intubation or ICU admission. Independent predictors of failure of ward management included chronic renal failure (odds ratio [OR], 7.20; p ≤ 0.001; 95% confidence interval [CI], 2.50-20.76), traumatic pneumothorax (OR, 8.70; p = 0.008; 95% CI, 1.76-42.93), concurrent sternal fracture (OR, 6.52; p ≤ 0.001; 95% CI, 2.53-16.80), drug use disorder (OR, 6.58; p = 0.032; 95% CI, 1.17-36.96), and emergency department oxygen requirement or oxygen saturation less than 95% (OR, 2.38; p = 0.018; 95% CI, 1.16-4.86). Mortality was higher in patients with delayed ICU care versus patients with successful ward disposition (21.1% vs. 0.8%; p < 0.001).

CONCLUSION

Our results suggest that the majority of isolated rib cage fractures in older patients are safely managed on the ward with exceedingly low ward failure rates (1.1%). Patients with failure of ward management have significantly higher mortality, and we have identified predictors of failing the ward.

Association Between Trauma Center Level and Outcomes of Adult Patients with Motorcycle Crash-Related Injuries in the United States

BACKGROUND

Motorcycle crash-related injury mechanism is a criterion in the Centers for Disease Control and Prevention field triage guidelines of injured patients, with a recommendation to transport affected patients to a trauma center need not be the highest level.

OBJECTIVE

This study examines the evidence behind this recommendation because severe injuries can result from motorcycle crashes and patients can benefit from treatment at higher-level trauma centers.

METHODS

This retrospective cohort study used the National Trauma Data Bank 2015 dataset. We conducted descriptive analyses (univariate and bivariate) followed by adjusted multivariate analysis to examine the association between trauma center designation levels and survival to hospital discharge.

RESULTS

A total of 28,821 patients with motorcycle injuries were included. Most patients were men (n = 25,361; 88%) and aged between 16 and 64 years (n = 26,989; 93.6%). Survival rates were higher in level II (n = 10,658; 95.3%) and III (n = 2,129; 95.5%) trauma centers compared to level I centers (n = 14,498; 94.6%). After adjusting for confounders, decreased survival to hospital discharge was noted for patients treated at level III trauma centers compared to those at level I centers (odds ratio 0.543; 95% confidence interval 0.390-0.729). No difference in survival was noted between level I and II centers.

CONCLUSIONS

Patients with motorcycle crash-related injuries treated at higher-level trauma center (I or II) had increased survival. This warrants a re-evaluation and adjustment of the field triage criterion for such patients. Examining the evidence behind field triage guidelines in trauma systems is needed for improved patient outcomes.

Mortality Factors in Geriatric Blunt Trauma Patients: Creation of a Highly Predictive Statistical Model for Mortality Using 50,765 Consecutive Elderly Trauma Admissions from the National Sample Project

Elderly patients are at high risk for mortality after injury. We hypothesized that trauma benchmarking efforts would benefit from development of a geriatric-specific model for risk-adjusted analyses of trauma center outcomes. A total of 57,973 records of elderly patients (age older than 65 years), which met our selection criteria, were submitted to the National Trauma Database and included within the National Sample Project between 2003 and 2006. These cases were used to construct a multivariable logistic regression model, which was compared with the American College of Surgeons Committee on Trauma's Trauma Quality Improvement Project's (TQIP) existing model. Additional spline regression analyses were performed to further objectively quantify the physiologic differences between geriatric patients and their younger counterparts. The geriatric-specific and TQIP mortality models shared several covariates: age, Injury Severity Score, motor component of the Glasgow Coma Scale, and systolic blood pressure. Our model additionally used temperature and the presence of mechanical ventilation. Our geriatric-specific regression mode generated a superior c-statistic as compared with the TQIP approximation (0.85 vs 0.77; P = 0.048). Spline analyses demonstrated that elderly patients appear to be less likely to tolerate relative hypotension with higher observed mortality at initial systolic blood pressures of 90 to 130 mmHg. Although the TQIP model includes a single age component, these data suggest that each variable needs to be adjusted for age to more accurately predict mortality in the elderly. Clearly, a separate geriatric model for predicting outcomes is not only warranted, but necessary.

Undertriaged trauma patients: Who are we missing?

BACKGROUND

Trauma team activation (TTA) criteria, set by the American College of Surgeons Committee on Trauma, are used to identify patients prehospital who are at highest risk for severe injury and mobilize the optimal resources. Patients are undertriaged if they are severely injured (Injury Severity Score, ≥16) but do not meet TTA criteria. This study examined the epidemiology and injury patterns of undertriaged patients and potential clinical effects.

METHODS

All patients presenting to our Level I trauma center (June 1, 2017 to May 31, 2018) were screened for inclusion using modified TTA criteria (mTTA), that is, age over 70 years added to the standard American College of Surgeons Committee on Trauma TTA criteria. Demographics, injury/clinical data, and outcomes of undertriaged patients were analyzed. Undertriaged patients were further subcategorized as "high-risk" if they expired or required emergent intervention.

RESULTS

233 undertriaged patients were identified from 1423 routine trauma consults (16%). Mean Injury Severity Score was 20 (range, 16-43). Most undertriage occurred following blunt trauma (n = 224, 96%), especially motor vehicle collisions (n = 66, 28%) and auto versus pedestrian collisions (n = 57, 24%). Thirty-two (14%) patients were identified as high-risk undertriaged patients: 16 (50%) required emergency surgery (mainly craniectomy; n = 10, 63%), 5 (16%) required angioembolization, and 14 patients (44%) died. In this high-risk group, the cause of death was almost exclusively traumatic brain injury (TBI) (n = 13, 93%). Of the patients who died of TBI, the majority had a depressed Glasgow Coma Scale score on presentation to the ED (<11) (n = 10, 77%) despite not meeting field criteria for TTA.

CONCLUSION

Using mTTA criteria, undertriage rates are relatively low, particularly after penetrating trauma. However, there is a high-risk population that is not captured, among whom mortality and need for emergent intervention are high. Most undertriage deaths are secondary to severe TBI. Despite not qualifying for highest-level activation, patients with head trauma and Glasgow Coma Scale score less than 11 on admission are at high-risk for adverse outcomes and additional resource mobilization should be considered.

Retrospective Analysis of Geriatric Major Trauma Patients Admitted in the Shock Room of a Swiss Academic Hospital: Characteristics and Prognosis

Increased life expectancy exposes a great number of elderly people to serious accidents, thus increasing the amount of major geriatric trauma cases. The aim of our study was to determine the profile of elderly patients undergoing major trauma, and the contributing factors predicting mortality in this specific patient group, compared to the younger population. Retrospective analysis of 1051 patients with major trauma admitted over ten years in a Level-1 trauma center was performed. Data collected were: history, nature and type of trauma; age and sex; vital signs on admission; injury severity score; shock index; comorbidities; coagulation diathesis; injury patterns; emergency measures taken; main diagnosis; mortality; and length of hospital and intensive care unit (ICU) stay. Geriatric patients admitted for major trauma have a mortality rate almost four times greater (47%) than their younger counterparts (14%) with the same ISS. According to statistical regression analysis, anti-platelet therapy (OR 3.21), NACA (National Advisory Committee for Aeronautics) score (OR 2.23), GCS (OR 0.83), ISS (OR 1.07) and age (OR 1.06) are the main factors predicting mortality. Conclusion: Geriatric major trauma patients admitted to our trauma resuscitation area have a high mortality rate. Age, GCS, ISS and NACA scores as well as anti-platelet therapy are the main factors predicting mortality.

Geriatric Trauma - A Rising Tide. Assessing Patient Safety Challenges in a Vulnerable Population Using Norwegian Trauma Registry Data and Focus Group Interviews: Protocol for a Mixed Methods Study

BACKGROUND

Elderly trauma patients constitute a vulnerable group, with a substantial risk of morbidity and mortality even after low-energy falls. As the world's elderly population continues to increase, the number of elderly trauma patients is expected to increase. Limited data are available about the possible patient safety challenges that elderly trauma patients face. The outcomes and characteristics of the Norwegian geriatric trauma population are not described on a national level.

OBJECTIVE

The aim of this project is to investigate whether patient safety challenges exist for geriatric trauma patients in Norway. An important objective of the study is to identify risk areas that will facilitate further work to safeguard and promote quality and safety in the Norwegian trauma system.

METHODS

This is a population-based mixed methods project divided into 4 parts: 3 quantitative retrospective cohort studies and 1 qualitative interview study. The quantitative studies will compare adult (aged 16-64 years) and elderly (aged ≥65 years) trauma patients captured in the Norwegian Trauma Registry (NTR) with a date of injury from January 1, 2015, to December 31, 2018. Descriptive statistics and relevant statistical methods to compare groups will be applied. The qualitative study will comprise focus group interviews with doctors responsible for trauma care, and data will be analyzed using a thematic analysis to identify important themes.

RESULTS

The project received funding in January 2019 and was approved by the Oslo University Hospital data protection officer (No. 19/16593). Registry data have been extracted for 33,344 patients, and the analysis of these data has begun. Focus group interviews will be conducted from spring 2020. Results from this project are expected to be ready for publication from fall 2020.

CONCLUSIONS

By combining data from the NTR with interviews with doctors responsible for treatment and transfer of elderly trauma patients, we will provide increased knowledge about trauma in Norwegian geriatric patients on a national level that will form the basis for further research aiming at developing interventions that hopefully will make the trauma system better equipped to manage the rising tide of geriatric trauma.

Prehospital Vital Signs Accurately Predict Initial Emergency Department Vital Signs

INTRODUCTION

Prehospital vital signs are used to triage trauma patients to mobilize appropriate resources and personnel prior to patient arrival in the emergency department (ED). Due to inherent challenges in obtaining prehospital vital signs, concerns exist regarding their accuracy and ability to predict first ED vitals.

HYPOTHESIS/PROBLEM

The objective of this study was to determine the correlation between prehospital and initial ED vitals among patients meeting criteria for highest levels of trauma team activation (TTA). The hypothesis was that in a medical system with short transport times, prehospital and first ED vital signs would correlate well.

METHODS

Patients meeting criteria for highest levels of TTA at a Level I trauma center (2008-2018) were included. Those with absent or missing prehospital vital signs were excluded. Demographics, injury data, and prehospital and first ED vital signs were abstracted. Prehospital and initial ED vital signs were compared using Bland-Altman intraclass correlation coefficients (ICC) with good agreement as >0.60; fair as 0.40-0.60; and poor as <0.40).

RESULTS

After exclusions, 15,320 patients were included. Mean age was 39 years (range 0-105) and 11,622 patients (76%) were male. Mechanism of injury was blunt in 79% (n = 12,041) and mortality was three percent (n = 513). Mean transport time was 21 minutes (range 0-1,439). Prehospital and first ED vital signs demonstrated good agreement for Glasgow Coma Scale (GCS) score (ICC 0.79; 95% CI, 0.77-0.79); fair agreement for heart rate (HR; ICC 0.59; 95% CI, 0.56-0.61) and systolic blood pressure (SBP; ICC 0.48; 95% CI, 0.46-0.49); and poor agreement for pulse pressure (PP; ICC 0.32; 95% CI, 0.30-0.33) and respiratory rate (RR; ICC 0.13; 95% CI, 0.11-0.15).

CONCLUSION

Despite challenges in prehospital assessments, field GCS, SBP, and HR correlate well with first ED vital signs. The data show that these prehospital measurements accurately predict initial ED vitals in an urban setting with short transport times. The generalizability of these data to settings with longer transport times is unknown.

Success Of An Expedited Emergency Department Triage Evaluation System For Geriatric Trauma Patients Not Meeting Trauma Activation Criteria

Background

Geriatric patients are at increased risk of injury following low-energy mechanisms and are less tolerant of injury. Current criteria for trauma team activation (TTA) often miss these injuries. We evaluated a novel triage process for an expedited Emergency Medicine Physician evaluation protocol (T3) for at-risk geriatric sub-populations not meeting trauma team activation (TTA) criteria.

Methods

Retrospective review of injured patients (≥65 years) from a Level II Trauma Center with an Injury Severity Score (ISS < 16), prior to (Pre-T3, Jan 2007-Oct 2009), and after (Post-T3, Jan 2010-Oct 2012), implementation of T3, as well as a contemporary period (CP, Jan 2013-Oct 2015). Demographics, physiologic variables, and timeliness of care were measured. Rates of ICU admission, operative procedures and lengths of stay and in-hospital mortality were compared for all periods. Logistic regression analysis determined variables independently associated with mortality.

Results

Post-T3, 49.2% of geriatric registry patients underwent T3 with a reduction in key time intervals. Median time to evaluation (42.1 mins vs 61.7 min, p<0.001), median time to CT (161.3 mins vs 212.9 mins, p<0.001) and EDLOS (364.6 mins vs 451.5 mins, p=0.023) were all reduced compared to non-expedited evaluations. There was no change in mortality after the implementation of the protocol.

Conclusion

The T3 protocol expedited patient evaluation of at-risk geriatric patients that would not otherwise meet TTA criteria. The new process met the goals of the American College of Surgeons Trauma Quality Improvement Program while conserving resources.

Trauma in elderly patients: a study of prevalence, comorbidities and gender differences

AIM

Trauma, in geriatric patients, increases with age, and is a leading cause of disability and institutionalization, resulting in morbidity and mortality. The aim of our study was to analyse the prevalence of trauma, the related risk factors, mortality and sex differences in the prevalence in a geriatric population.

PATIENTS AND METHOD

We observed 4,554 patients (≥65 years) with home injuries or car accidents. Patients were evaluated with ISS (Injury Severity Score) and major trauma with ATLS (Advanced Trauma Life Support). The instrumental investigation was in the first instance, targeted X-Ray or whole-body CT.

RESULTS

In over four years of study we treated 4,554 geriatric: 2,809 females and 1,745 Males. When the type of trauma was analysed the most common was head injury, followed by fractures of lower and upper limbs. In our experience hospitalization mainly involved patients over 80. In all patients mortality during assessment was 0.06%.

DISCUSSION

The geriatric patient is often defined as a "frail elderly", for the presence of a greater "injury sensitivity". This is due to the simultaneous presence of comorbidity, progressive loss of full autonomy and exposure to a high risk of traumatic events. Optimal management of the trauma patient can considerable reduce mortality and morbidity.

CONCLUSIONS

Falls and injuries in geriatric age are more frequent in women than in men. Among typical elder comorbidities, osteoporosis certainly causes a female preponderance in the prevalence of fractures. Our discharge data demonstrate that disability, which requires transfer to health care institutions, has a greater effect on women than men.

Correlation between field triage criteria and the injury severity score of trauma patients in a French inclusive regional trauma system

Background

In France, the pre-hospital field triage of trauma patients is currently based on the Vittel criteria algorithm. This algorithm was originally created in 2002 before the stratification of trauma centers and, at the national level, has not been revised since. This could be responsible for the overtriage of trauma patients in Level I Trauma Centers. The principal aim of this study was to evaluate the correlation between each Vittel field triage criterion and trauma patients’ Injury Severity Score.

Methods

Our Level I Trauma Center receives an average of 300 trauma patients per year. Demographic and physiological data, along with the entire trauma patient management process and Vittel field triage criteria, are recorded in a local trauma registry. The Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS) are calculated after a complete assessment of the trauma victim during their in-hospital management. Results were concerned with the presence of an ISS of greater than 15, which defined a major trauma patient; mortality within 30 days; and admission to the intensive care unit. This study is a registry analysis from January 2013 to September 2017.

Results

Of the 1373 patients in the registry, 1151 were included in the analysis with a mean age of 43 years (± 19) and a median ISS of 13 (IQR = 5–22), where 887 (77%) were male. Nine of the 24 Vittel criteria were associated with an ISS > 15. In a multivariate analysis, no criterion related to kinetic elements was significantly correlated with an ISS > 15, mortality within 30 days, or admission to intensive care. Three algorithm categories were predictive of a major trauma patient (ISS > 15): physiological variables, pre-hospital resuscitation, and physical injuries, while kinetic elements were not.

Conclusions

Criteria related to physiological variables, pre-hospital resuscitation, and physical injuries are the most relevant to predicting the severity of a trauma patient’s condition. A revision of the VCA could potentially have beneficial effects on the over and undertriage phenomena, which constitute ongoing medical and financial concerns.

Identification of Emergency Care-Sensitive Conditions and Characteristics of Emergency Department Utilization

IMPORTANCE

Monitoring emergency care quality requires understanding which conditions benefit most from timely, quality emergency care.

OBJECTIVES

To identify a set of emergency care-sensitive conditions (ECSCs) that are treated in most emergency departments (EDs), are associated with a spectrum of adult age groups, and represent common reasons for seeking emergency care and to provide benchmark national estimates of ECSC acute care utilization.

DESIGN, SETTING, AND PARTICIPANTS

A modified Delphi method was used to identify ECSCs. In a cross-sectional analysis, ECSC-associated visits by adults (aged ≥18 years) were identified based on International Statistical Classification of Diseases, Tenth Revision, Clinical Modification diagnosis codes and analyzed with nationally representative data from the 2016 US Nationwide Emergency Department Sample. Data analysis was conducted from January 2018 to December 2018.

MAIN OUTCOMES AND MEASURES

Identification of ECSCs and ECSC-associated ED utilization patterns, length of stay, and charges.

RESULTS

An expert panel rated 51 condition groups as emergency care sensitive. Emergency care-sensitive conditions represented 16 033 359 of 114 323 044 ED visits (14.0%) in 2016. On average, 8 535 261 of 17 886 220 ED admissions (47.7%) were attributed to ECSCs. The most common ECSC ED visits were for sepsis (1 716 004 [10.7%]), chronic obstructive pulmonary disease (1 273 319 [7.9%]), pneumonia (1 263 971 [7.9%]), asthma (970 829 [6.1%]), and heart failure (911 602 [5.7%]) but varied by age group. Median (interquartile range) length of stay for ECSC ED admissions was longer than non-ECSC ED admissions (3.2 [1.7-5.8] days vs 2.7 [1.4-4.9] days; P < .001). In 2016, median (interquartile range) ED charges per visit for ECSCs were $2736 ($1684-$4605) compared with $2179 ($1118-$4359) per visit for non-ECSC ED visits (P < .001).

CONCLUSIONS AND RELEVANCE

This comprehensive list of ECSCs can be used to guide indicator development for pre-ED, intra-ED, and post-ED care and overall assessment of the adult, non-mental health, acute care system. Health care utilization and costs among patients with ECSCs are substantial and warrant future study of validation, variations in care, and outcomes associated with ECSCs.

Flail Chest: Less Deadly than Originally Thought

INTRODUCTION

Flail chest is considered a highly morbid condition with reported mortality ranging from 10 to 20%. It is often associated with other severe injuries, which may complicate management and interpretation of outcomes. The physiologic impact and prognosis of isolated flail chest injury is poorly defined.

METHODS

This is a National Trauma Databank study. All patients from 1/2007 to 12/2014 admitted with flail chest were extracted. Patients with head or abdominal AIS ≥3, dead on arrival, or transferred, were excluded. Primary outcome was mortality; secondary outcomes were need for mechanical ventilation and pneumonia.

RESULTS

Of the 1,047,519 patients with blunt chest injury, 14,718 (1.4%) patients presented with flail chest, and 8098 (0.77%) met inclusion criteria. The most commonly associated intrathoracic injuries were hemothorax (57.9%) and lung contusions (63.0%), while sternal fracture (8.8%) and cardiac contusion (2.5%) were less common. In total, 29.8% of patients required mechanical ventilation, and 11.2% developed pneumonia. Overall mortality was 5.6%. On multivariable analysis, age >65 and need for mechanical ventilation were independent risk factors for mortality (OR 6.02, 3.75, respectively, p < 0.001). Independent predictors for mechanical ventilation included cardiac or pulmonary contusion and sternal fractures (OR 3.78, 2.38, 2.29, respectively, p < 0.001). Need for mechanical ventilation was an independent predictor of pneumonia (OR 13.18, p < 0.001).

CONCLUSIONS

Mortality in isolated flail chest is much lower than previously reported. Fewer than 30% of patients require mechanical ventilation. Need for mechanical ventilation, however, is independently associated with mortality and pneumonia. Age >65 is an independent risk factor for adverse outcomes, and these patients may benefit by more aggressive monitoring and treatment.

Old Age With a Traumatic Mechanism of Injury Should Be a Trauma Team Activation Criterion

BACKGROUND

Age is not a standard trauma team activation (TTA) criteria recommended by the Committee on Trauma. However, there is concern that vital signs in elderly patients are often unreliable. In addition, elderly patients are at risk after moderate trauma. At our institution, age ≥ 70 years with traumatic mechanisms of injury has been a TTA criterion for more than 15 years.

OBJECTIVE

Our aim was to determine whether age ≥70 years as a TTA criterion appropriately identifies patients in need of additional resources without significantly impacting overtriage rates.

METHODS

We conducted a retrospective trauma registry study of TTAs for age ≥ 70 years from January 2012-December 2016. Demographics, injury data, Injury Severity Score (ISS), procedures, emergency department (ED) disposition, and hospital data were collected. Primary outcome was mortality, secondary outcomes were intensive care unit (ICU) and hospital lengths of stay. Patients were stratified into meeting standard criteria (TTA-S) or activated based on age alone (TTA-A). TTA patients with ISS > 15, ED intubation, ICU admission, immediate operating room or catheter-based intervention, and mortalities were appropriately triaged.

RESULTS

During the study, there were 5436 total TTAs. Seven hundred and thirty-nine TTAs in patients aged ≥ 70 years, of which 198 (26.8%) were TTA-S and 541 (73.2%) were TTA-A. In the TTA-A group, 49 (9%) patients died, 149 (27.5%) had ISS > 15, 65 (12%) underwent immediate intervention, 72 (13%) had ED intubations, and 306 (56.6%) required admission to the ICU. The overtriage rate in the TTA-A group was 39.6%.

CONCLUSIONS

Elderly patients with severe trauma patients often do not meet the standard TTA criteria, resulting in potentially dangerous undertriage. Addition of age (≥70 years) criterion for TTA reduces undertriage and does not result in excessive overtriage.

Improvement in geriatric trauma outcomes in an evolving trauma system

Background

The elderly trauma patient has increased mortality compared with younger patients. During the last 15 years, initial treatment of severely injured patients at Oslo University Hospital Ulleval (OUHU) has changed resulting in overall improved outcomes. Whether this holds true for the elderly trauma population needs exploration and was the aim of the present study.

Methods

We performed a retrospective study of 2628 trauma patients 61 years or older admitted to OUHU during the 12-year period, 2002-2013. The population was stratified based on age (61-70 years, 71-80 years, 81 years and older) and divided into time periods: 2002-2009 (P1) and 2010-2013 (P2). Multiple logistic regression models were constructed to identify clinically relevant core variables correlated with mortality and trauma team activation rate.

Results

Crude mortality decreased from 19% in P1 to 13% in P2 (p<0.01) with an OR of 0.77 (95 %CI 0.65 to 0.91) when admitted in P2. Trauma team activation rates increased from 53% in P1 to 72% in P2 (p<0.01) with an OR of 2.16 (95% CI 1.93 to 2.41) for being met by a trauma team in P2. Mortality increased from 10% in the age group 61-70 years to 26% in the group above 80 years. Trauma team activation rates decreased from 71% in the age group 61-70 years to 50% in the age group older than 80 years. Median ISS were 17 in all three age groups and in both time periods.

Discussion

Development of a multidisciplinary dedicated trauma service is associated with increased trauma team activation rate as well as survival in geriatric trauma patients. As expected, mortality increased with age, although inversely related to the likelihood of being met by a trauma team. Trauma team activation should be considered for all trauma patients older than 70 years.

Impact of Type and Number of Complications on Mortality in Admitted Elderly Blunt Trauma Patients

BACKGROUND

Advanced age and comorbidities are recognized risk factors for adverse outcomes in elderly trauma patients. However, the contribution of the number and type of complications to in-hospital mortality in elderly blunt trauma admissions has not been extensively studied.

METHODS

A retrospective review of the trauma registry at a level 1 trauma center for blunt trauma patients age ≥65 y hospitalized for at least 2 d between 2010 and 2015.

RESULTS

There were 2467 admissions, with a median age of 81 y and median injury severity score of 9. The most common mechanism of injury was a low-level fall. Approximately 19.6% of admissions had a complication: 11.1% major complications, 8.6% other complications. The in-hospital mortality rate was significantly different (P < 0.001) among the three groups at 16.1% of major complications group, 7.1% of other, and 2.1% of no complications (P < 0.001). On multivariate logistic regression, each major complication increased the odds for in-hospital mortality by 1.59-fold.

CONCLUSIONS

Complications are not infrequent in elderly blunt trauma admissions, despite a generally lower energy mechanism of injury. Each major complication is associated with increased odds of mortality. Multifaceted interventions for prevention and mitigation of complications are indicated.

Undertriage of major trauma patients at a university hospital: a retrospective cohort study

Background

Studies show increased mortality among severely injured patients not met by trauma team. Proper triage is important to ensure that all severely injured patients receive vital trauma care. In 2017 a new national trauma plan was implemented in Norway, which recommended the use of a modified version of “Guidelines for Field Triage of Injured Patients” to identify severely injured patients.

Methods

A retrospective study of 30,444 patients admitted to Haukeland University Hospital in 2013, with ICD-10 injury codes upon discharge. The exclusion criteria were department affiliation considered irrelevant when identifying trauma, patients with injuries that resulted in Injury Severity Score < 15, patients that did receive trauma team, and patients admitted > 24 h after time of injury. Information from patient records of every severely injured patient admitted in 2013 was obtained in order to investigate the sensitivity of the new guidelines.

Results

Trauma team activation was performed in 369 admissions and 85 patients were identified as major trauma. Ten severely injured patients did not receive trauma team resuscitation, resulting in an undertriage of 10.5%. Nine out of ten patients were men, median age 54 years. Five patients were 60 years or older. All of the undertriaged patients experienced fall from low height (< 4 m). Traumatic brain injury was seen in six patients. Six patients had a Glasgow Coma Scale score ≤ 13. The new trauma activation guidelines had a sensitivity of 95.0% in our 2013 trauma population. The degree of undertriage could have been reduced to 4.0% had the guidelines been implemented and correctly applied.

Conclusions

The rate of undertriage at Haukeland University Hospital in 2013 was above the recommendations of less than 5%. Use of the new trauma guidelines showed increased triage precision in the present trauma population.

Evaluation of the trauma triage accuracy in a Level 1 Australian trauma centre

OBJECTIVES

To assess the rate of undertriage of major trauma patients and to assess factors contributing to undertriage in a modern Australian Level 1 trauma centre.

METHODS

A retrospective case series of 600 consecutive major trauma (injury severity score [ISS] >15) patients admitted to Royal Perth Hospital (RPH) during 2015 was performed. Data were compiled via the prospectively maintained hospital trauma registry for all patients admitted with a major trauma during the study period. Results were analysed for patient demographics, mechanism and outcomes. The primary outcome of the study was to determine the rate of undertriage of major trauma at RPH by establishing whether or not the trauma team activation page was correctly sent at the time of patient arrival based on hospital criteria.

RESULTS

The average age of patients in the study population was 46.5 (±21.5) years and the mean ISS was 24.7 (±9.3). The most common mechanism of injury was falls, motor vehicle accidents and motorbike accidents. One hundred and sixty-nine patients (28%) did not have trauma team activation on arrival to the ED. Among these patients, 132 did not fulfil the RPH trauma activation criteria. The remaining 37 patients (6.1%) did meet the criteria and were considered undertriaged. Subgroup analysis showed a statistically significant difference in age between the patients who had trauma team activation (42.7 ± 19.5 years) and those who did not (55.9 ± 23.3 years).

CONCLUSION

In this cohort of major trauma, a 6.1% undertriage performance of the triage tool was observed. Sub-analysis of the data showed that elderly patients were more likely to be undertriaged.

The Age of Undertriage: Current Trauma Triage Criteria Underestimate The Role of Age and Comorbidities in Early Mortality

BACKGROUND

National guidelines recommend that prehospital and emergency department (ED) criteria identify patients who might benefit from trauma center triage and highest-level trauma team activation. However, some patients who are seemingly "stable" in the field and do not meet the standard criteria for trauma activation still die.

OBJECTIVES

The purpose of this study was to identify these at-risk patients to potentially improve triage algorithms.

METHODS

Patients enrolled in the National Trauma Data Bank (2007-2012) were included. All adult blunt trauma patients that were stable in the field and upon arrival to the ED (defined as a Glasgow Coma Scale score of 13-15, a heart rate ≤120 beats/min, systolic blood pressure ≥90 mm Hg, and diastolic blood pressure ≤200 mm Hg) and did not meet the standard criteria for the highest-level trauma team activation as defined by the American College of Surgeons were included. Demographic, clinical, and injury data including comorbidities, ED vitals, and outcome were collected. Regression models were used to identify independent risk factors for mortality.

RESULTS

A total of 1,003,350 patients were stable in both the field and ED. Of these 11,010 (1.1%) died, including 1785 (0.2%) who died within 24 hours of hospital admission. The mortality in patients ≥60 years of age was 2.6%, and in patients ≥60 years of age with either a cerebrovascular accident (CVA) or congestive heart failure (CHF) was 5.4%. Age ≥60 years was a significant independent predictor of early mortality (odds ratio [OR] 4.53, p < 0.001). CHF (OR 1.88, p < 0.001) and a history of stroke (OR 1.52, p < 0.001) were also significant independent predictors of mortality.

CONCLUSIONS

Despite apparent evidence of both prehospital stability and stability upon arrival to the ED, patients ≥60 years of age and with a history of CHF or CVA have a significantly increased risk of early mortality after blunt trauma. These patients are at risk for subsequent clinical deterioration and should be considered for early transfer to a trauma center with highest-level activation.

The Impact of Enhanced Intensive Care on Outcome of Major Trauma Patients in a Regional Hospital in Hong Kong

Objectives

To describe an updated epidemiology of major trauma cases presenting to a regional hospital in Hong Kong and to analyse the impact of enhanced intensive care on the outcome of major trauma patients.

Methods

This was a retrospective comparative study. In late 2004, we amended our trauma care system with enhancement of intensive care in the management of major trauma patients. An 18-month period was chosen before and after the amendment respectively and patients' data and crude mortality rate between the two periods were compared. Stratified analyses based on mechanism of injury, injury severity and physiological parameters were also performed. Finally, a TRISS analysis was included.

Results

Altogether 163 and 155 patients were included in our study from the two periods respectively. The majority involved blunt injury and one third of them had injury severity score (ISS) greater than 15. Road traffic accidents and fall from height remained as the two leading causes of major trauma. The median length of stay in the intensive care unit increased for one day (p<0.01) in the later period but the median total length of stay in hospital remained the same. The mortality rate decreased from 10.4% to 9.7% (p=0.82).

Conclusion

With enhanced intensive care, there is an apparent decrease in mortality of major trauma patients but its significance needs to be determined with a larger scale study.

Evidence-Based Care of Geriatric Trauma Patients

The doubling of the geriatric population over the next 20 years will challenge the existing health care system. Optimal care of geriatric trauma patients will be of paramount importance to the health care discussion in America. These patients warrant special consideration because of altered anatomy, physiology, and the resultant decreased ability to tolerate the stresses imposed by traumatic insult. Despite increased risk for worsened outcomes, nearly half of all geriatric trauma patients will be cared for at nondesignated trauma centers. Effective communication is crucial in determining goals of care and arriving at what patients would consider a meaningful outcome.

Clinical Characteristics and Outcome in Elderly Patients with Traumatic Brain Injury: For Establishment of Management Strategy

In recent years, instances of neurotrauma in the elderly have been increasing. This article addresses the clinical characteristics, management strategy, and outcome in elderly patients with traumatic brain injury (TBI). Falls to the ground either from standing or from heights are the most common causes of TBI in the elderly, since both motor and physiological functions are degraded in the elderly. Subdural, contusional and intracerebral hematomas are more common in the elderly than the young as the acute traumatic intracranial lesion. High frequency of those lesions has been proposed to be associated with increased volume of the subdural space resulting from the atrophy of the brain in the elderly. The delayed aggravation of intracranial hematomas has been also explained by such anatomical and physiological changes present in the elderly. Delayed hyperemia/hyperperfusion may also be a characteristic of the elderly TBI, although its mechanisms are not fully understood. In addition, widely used pre-injury anticoagulant and antiplatelet therapies may be associated with delayed aggravation, making the management difficult for elderly TBI. It is an urgent issue to establish preventions and treatments for elderly TBI, since its outcome has been remained poor for more than 40 years.
