Morbidity and mortality in elderly trauma patients

The Characteristics of Severely Injured Trauma Patients Admitted to a Level I Trauma Center with Pre-Injury Use of Oral Anticoagulation (OAC) or Antiplatelet Therapy (APT)

Background: Little is known about the impact of pre-injury OAC/APT on severely injured trauma patients admitted to a level I trauma center. Our study focused on impact of pre-injury OAC/APT on the outcomes of this specific cohort of patients. Methods: A retrospective cohort study on 356 severely injured trauma patients admitted to the resuscitation room in a level I trauma center between 2015 and 2020 was carried out. Results: Of the 356 patients, 20.5% (n = 73) were admitted with pre-injury OAC/APT. Falls from lower heights, categorized as low-energy trauma, were the primary mechanism of injury in patients with pre-injury OAC/APT. Patients with pre-injury OAC/APT were older (p < 0.001), had a higher proportion of severe traumatic brain injuries (TBI) (p < 0.001), and experienced significantly higher mortality rates during their hospital stay (60.3% vs. 15.9%; p < 0.001). There were significant correlations between pre-injury OAC/APT and advanced age (p < 0.001) as well as the severity of head injury (p < 0.001). Patients with pre-injury OAC/APT exhibited significantly higher mortality rates; especially in patients with pre-injury oral anticoagulation therapy. The highest mortality rates were observed in patients with isolated TBI and pre-injury OAC/APT. Conclusions: Trauma patients with pre-injury OAC/APT presented with advanced age and low-energy trauma as the main mechanism of injury. Pre-injury OAC/APT significantly correlated with advanced age and the severity of head injuries, and it may serve as an additional prognostic factor for the outcome of severely injured trauma patients.

Mortality in orthopedic patients: a retrospective review of 333 medical records

BACKGROUND

The burden of orthopedic admissions has notably increased in recent years. Managing orthopedic conditions is challenging in clinical settings. Orthopedic complaints often necessitate urgent medical intervention to prevent complications and mortality. Despite advancements in medical care, some patients still experience severe complications, extended hospital stays, and death following orthopedic admission. In this study, we aimed to explore the distribution of potential risk factors and common patterns in orthopedic patients who died during their hospitalization.

MATERIALS AND METHODS

All the patients who were admitted to three tertiary trauma centers with orthopedic complaints from 2010 to 2023 and died during hospitalization were enrolled in this study. Demographic, injury-related, laboratory-related, intervention-related, complication-related, and healthcare-related data were extracted using the patient's medical records. Descriptive analysis of the collected data was performed using the SPSS version 27 software.

RESULTS

333 patients who died in the hospital with orthopedic complaints were included in the study and examined. The mean age of patients in this study was 67.89 years, comprising 68% males and 32% females. Trauma was patients' most common clinical cause of admission (63.7%). The prevalence of death before surgery, death during the first 24 h after surgery, and death after 24 h postoperatively were 26.4%, 18.6%, and 55%, respectively.

CONCLUSIONS

Our findings suggest a high prevalence of trauma as a clinical complaint leading to death among patients, emphasizing the importance of developing an integrated protocol for trauma preventive strategies.

Sex-Based Differences in Polytraumatized Patients between 1995 and 2020: Experiences from a Level I Trauma Center

Background/Objectives: The aim of this study was to examine sex-related differences in the outcomes of polytraumatized patients admitted to a level I trauma center. Methods: This was a retrospective data analysis of 980 consecutive polytraumatized patients admitted to a single level I trauma center between January 1995 and December 2020. Results: Among all patients, about 30% were female, with a significantly higher age and significantly higher rates of suicidal attempts. No sex-related differences regarding injury severity or trauma mechanisms could be seen, but female patients had significantly higher overall in-hospital mortality rates compared to male patients. Even in the elderly group of patients, elderly female patients were significantly older compared to elderly male patients, with significantly increased lengths of hospital stay. In the elderly group of patients, no sex-related differences regarding injury severity, trauma mechanisms or mortality could be detected. Multivariate analysis revealed suicidal attempt, severe head injury and age > 54 years as independent prognostic factors in the survival of polytraumatized patients. Conclusions: Distinctive sex-related differences can be found, with female polytraumatized patients being significantly older and having higher overall mortality rates with significantly increased LOS. Our study suggests a strong sex-independent influence of age, suicidal attempt and severe head injury on the outcomes of polytraumatized patients.

Simple parameters to identify patients treatable with early definitive fixation: A nationwide study

INTRODUCTION

Early appropriate care (EAC) is widely accepted as a safe strategy to perform early definitive fracture fixation, and good clinical outcomes have been reported in selected, multiply injured patients, although the optimal candidate for early definitive fixation (EDF) has not been validated. The aim of this study was to identify simple clinical parameters to help select patients who could undergo EDF.

METHODS

Patients with extremity injuries who underwent open reduction and internal fixation were retrospectively identified, using data from the Japan Trauma Data Bank (JTDB). Age, vital signs on hospital presentation, and the injury severity score (ISS) were examined by transforming these variables to binary categories. Patients were divided into categories based on these variables, and in-hospital mortality was compared between patients treated with EDF (EDF group) and those treated without EDF (non-EDF group) in each category.

RESULTS

Of the 12,735 patients who were eligible for the analyses, 3706 (29.1 %) were managed with EDF. In-hospital mortality was significantly higher in the EDF group than in the non-EDF group among patients with a low Glasgow Coma Scale (GCS) score (<13), low systolic blood pressure (sBP) (<90 mmHg), and ISS≥15, whereas in-hospital mortality was comparable between the EDF and non-EDF groups among patients with GCS scores ≥13, sBP ≥90 mmHg, and ISS <15.

DISCUSSION

In this large nationwide database of trauma patients, EDF was performed without affecting mortality in patients with GCS scores ≥13 and sBP ≥90 mmHg on hospital presentation, as well as ISS <15. These parameters might be useful as screening tools to select the candidates who could be treated with EDF safely.

Factors Associated With Triage Decisions in Older Adult Trauma Patients: Impact on Mortality and Morbidity

INTRODUCTION

As medical advances have significantly increased the life expectancy among older adults, the number of older patients requiring trauma care has risen proportionately. Nevertheless, it is unclear among this growing population which sociodemographic and economic factors are associated with decisions to triage and transfer to level I/II centers. This study aims to assess for any association between patient sociodemographic characteristics, triage decisions, and outcomes during acute trauma care presentations.

METHODS

The National Trauma Data Bank was queried for patients aged 65 and older with an injury severity score > 15 between the years 2007 to 2017. Factors associated with subsequent levels of triage on presentation were assessed using multivariate logistic regression, and associations of levels of triage with outcomes of mortality, morbidity, and hospital length of stay are examined using logistic and linear regression models.

RESULTS

Triage of 210,310 older adult trauma patients showed significant findings. American Indian patients had higher odds of being transferred to level I/II centers, while Asian, Black, and Native Hawaiian patients had lower odds of being transferred to level I/II centers when compared to Caucasian patients (P < 0.001). Regarding insurance, self-pay (uninsured) patients were less likely to be transferred to a higher level of care; however, this was also demonstrated in private insurance holders (P < 0.001). Caucasian patients had significantly higher odds of mortality, with Black patients (odds ratio [OR] 0.80 [0.75, 0.85]) and American Indian patients (OR 0.87 [0.72, 1.04]) having significantly lower odds (P < 0.001). Compared to government insurance, private insurance holders (OR 0.82 [0.80, 0.85]) also had significantly lower odds of mortality, while higher odds among self-pay were observed (OR 1.75 [1.62, 1.90]), (P < 0.001).

CONCLUSIONS

Access to insurance is associated with triage decisions involving older adults sustaining trauma, with lower access increasing mortality risk. Factors such as race and gender were less likely to be associated with triage decisions. However, due to this study's retrospective design, further prospective analysis is necessary to fully assess the decisions that influence trauma triage decisions in this patient population.

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.

Free flaps for lower limb soft tissue reconstruction - A systematic review of complications in 'Silver Trauma' patients

BACKGROUND

There are 12.5 million people aged 65 years and older living in the UK. The annual incidence of open fracture is 30.7 per 10,000 person-years. In females, 42.9% of all open fractures occur in patients ≥ 65 years.

METHODS AND MATERIALS

Preferred Reporting for Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and the study is registered with PROSPERO (CRD42020209149). The aim was to compare the complication profiles of free fasciocutaneous flaps and free muscular flaps in patients aged over 60 years undergoing lower limb soft tissue reconstruction following an open lower limb fracture. The search strategy based on strict inclusion criteria included PubMed, Embase and Google Scholar.

RESULTS

15 papers were identified, including 46 patients with 10 free fasciocutaneous flaps and 41 free muscle flaps. There were 3 complications in the fasciocutaneous group (30%) and 9 complications in the muscle group (22%). There was a total of 1 secondary procedure in the fasciocutaneous group and 4 in the muscle group.

DISCUSSION

There is insufficient data to provide statistical comparison between free fasciocutaneous versus free muscle flaps for lower limb reconstruction performed in those aged over 60 years. This systematic review highlights evidence for the successful use of free tissue transfer in the older population following an open fracture injury and requiring lower limb reconstruction. There is no evidence to suggest the superiority of one tissue type over the other, with the inference that well vascularised tissue is the most significant factor impacting outcome.

Emergency readmissions following geriatric ground-level falls: How does frailty factor in?

BACKGROUND

Ground-level falls (GLFs) in older adults are increasing as life expectancy increases, and more patients are being discharged to skilled nursing facilities (SNFs) for continuity of care. However, GLF patients are not a homogenous cohort, and the role of frailty remains to be assessed. Thus, the aim of this study is to examine the impact of frailty on the in-hospital and 30-day outcomes of GLF patients.

MATERIALS AND METHODS

This is a cohort analysis from the Nationwide Readmissions Database 2017. Geriatric (age ≥65 years) trauma patients presenting following GLFs were identified and grouped based on their frailty status. The associations between frailty and 30-day mortality and emergency readmission were examined by multivariate regression analyses adjusting for patient demographics and injury characteristics.

RESULTS

A total of 100,850 geriatric GLF patients were identified (frail: 41% vs. non-frail: 59%). Frail GLF patients were younger (81[74-87] vs. 83[76-89] years; p<0.001) and less severely injured-Injury Severity Score [ISS] (4[1-9] vs. 5[2-9]; p<0.001). Frail patients had a higher index mortality (2.9% vs. 1.9%; p<0.001) and higher 30-day readmissions (14.0% vs. 9.8%; p<0.001). Readmission mortality was also higher in the frail group (15.2% vs. 10.9%; p<0.001), with 75.2% of those patients readmitted from an SNF. On multivariate analysis, frailty was associated with 30-day mortality (OR 1.75; p<0.001) and 30-day readmission (OR 1.49; p<0.001).

CONCLUSION

Frail geriatric patients are at 75% higher odds of mortality and 49% higher odds of readmission following GLFs. Of those readmitted on an emergency basis, more than one in seven patients died, 75% of whom were readmitted from an SNF. This underscores the need for optimization plans that extend to the post-discharge period to reduce readmissions and subsequent high-impact consequences.

The Association Between Serum Lactate Concentration, Base Deficit, and Mortality in Polytrauma Patients as a Prognostic Factor: An Observational Study

Introduction

In polytrauma patients, it is crucial to identify the severity of the injuries to ensure patient safety and survival. Polytrauma leads to hypotension and hypoperfusion, which results in an anaerobic metabolism with acidosis and a decrease in base excess. Thus, blood lactate levels above a certain threshold indicate the existence of global tissue hypoxia, which is a precursor to shock and multiple organ dysfunction syndrome (MODS). The serum lactate and base deficit (BD) levels are used in polytrauma patients as measures of damage severity and resuscitation endpoints and as a way to evaluate therapy efficacy and to predict outcomes. Thus, arterial blood gas analysis is of great value in assessing the status and prognosis of patients with polytrauma. There are few comparative studies on the predictive values of these markers in trauma patients. To determine which measure can more accurately predict the prognosis of polytrauma patients, the present study investigated the predictive values of mortality of these indicators for mortality within 48 hours of admission to the emergency room (ER) in patients with polytrauma.

Methods

This prospective study was designed for a single tertiary care center in northern India. We included 90 patients with polytrauma who were between the ages of 18 and 70 years, with the exception of pregnant women, who presented to the ER within six hours of injury with an injury severity score (ISS) >16, serum lactate level >2.0 mmol/L, and BD -4.0 mEq/L at the time of admission. If the patient's ISS was >16 at the time of ER presentation, arterial blood samples were drawn to determine the serum lactate and BD level at the time of admission and at 12, 24, and 48 hours intervals after ER admission. The primary outcome was the change in serum lactate and BD level in polytrauma. The secondary outcomes were an association of serum lactate and BD with mortality and the correlation between serum lactate with the BD and ISS with mortality of polytrauma patients. The timing of all outcome assessments was at 48 hours after each patient's ER admission.

Results

Lactate clearance from 0-12 hours (t = 2.28, p <0.05), 0-24 hours (t = 6.01, p <0.001), and 0-48 hours (t = 7.98, p <0.001) and a correction in BD from 0-24 (t = 2.68, p <0.01 ) and 0-48 hours (t = 5.46, p <0.001) were significantly higher in nonsurvivors as compared with survivors. In survivors and nonsurvivors, mean serum lactate levels (2.46 ± 1.46 versus 4.15 ± 2.99, t = 3.31, p <0.001, 95%Cl) and mean BD (-3.17 ± 2.58 versus -6.5 ± 4.91, t = 3.86, p <0.001, 95%CI) had a statistically significant difference. The serum lactate and BD levels at time of ER admission (r L0, BD0 = -0.765, p <0.01) and 48 hours after ER admission (r L48, BD 48 = -0.652, p <0.001) were highly negatively correlated.

Conclusion

In polytrauma patients, serum lactate and BD are simple, quick, and independent biochemical predictors of 48-hour mortality, and this single arterial blood test would thereby improve decision-making for resuscitation effectiveness. Prolonged lactate and BD normalization time were associated with higher mortality. Serum lactate and BD are negatively correlated. A higher ISS at admission was associated with a higher incidence of mortality in polytrauma patients.

The physiologic responses to a fluid bolus administration in old and young healthy adults

BACKGROUND

Organ function is known to decline with age. Optimizing cardiac, pulmonary and renal function in older adults has led to significant improvements in perioperative care. However, when substantial blood loss and fluid shifts occur, perioperative outcomes still remains poor, especially in older adults. We suspect that this could be due to age-related changes in endothelial function-an organ controlling the transport of fluid and solutes. The capillary filtration coefficient (CFC) is an important determinant of fluid transport. The CFC can be measured in vivo, which provides a tool to estimate endothelial barrier function. We have previously shown that the CFC increases when giving a fluid bolus resulting in increased vascular and extravascular volume expansion, in young adults. This study aimed to compare the physiologic determinants of fluid distribution in young versus older adults so that clinicians can best optimize perioperative fluid therapy.

METHODS

Ten healthy young volunteers (ages 21-35) and nine healthy older volunteers (ages 60-75) received a 10 mL/kg fluid bolus over the course of twenty minutes. Hemodynamics, systolic and diastolic heart function, fluid volumetrics and microcirculatory determinants were measured before, during, and after the fluid bolus.

RESULTS

Diastolic function was reduced in older versus younger adults before and after fluid bolus (P < 0.01). Basal CFC and plasma oncotic pressure were lower in the older versus younger adults. Further, CFC did not increase in older adults following the fluid bolus, whereas it did in younger adults (p < 0.05). Cumulative urinary output, while lower in older adults, was not significantly different (p = 0.059). Mean arterial pressure and systemic vascular resistance were elevated in the older versus younger adults (p < 0.05).

CONCLUSION

Older adults show a less reactive CFC to a fluid bolus, which could reduce blood to tissue transport of fluid. Diastolic dysfunction likely contributes to fluid maldistribution in older adults.

Predicting Mortality in Elderly Spine Trauma Patients

STUDY DESIGN

Retrospective analysis on prospectively collected data.

OBJECTIVE

The aim of this study was to construct a clinical prediction model for 90-day mortality in elderly patients with traumatic spine injuries.

SUMMARY OF BACKGROUND DATA

Spine trauma in the elderly population is increasing. Comparing elderly spine trauma patients to younger patients with similar injuries proves challenging due to the extensive comorbidities and frailty found in the elderly. There is a paucity of evidence to predict survival of elderly patients following traumatic spinal injuries.

METHODS

All patients 65+ with spine trauma presenting to a level I trauma center from 2010 to 2019 were reviewed from a prospectively maintained trauma registry. Retrospective chart review was performed to record injury, frailty scores, comorbidities, presence of spinal cord injury, imaging evidence of sarcopenia and osteopenia, mortality, and complications. We preselected 13 variables for our multivariable logistic regression model: hypotension on admission, gender, marital status, age, max Abbreviated Injury Scale, Modified Frailty Index, surgical treatment, hematocrit, white blood count, spinal cord injury, closed head injury, injury level and presence of high energy mechanism. The performance of the prediction model was evaluated using a concordance index and calibration plot. The model was internally validated via bootstrap approach.

RESULTS

Over the 9-year period, 1746 patients met inclusion criteria; 359 (20.6%) patients died within 90 days after presenting with spine trauma. The most important predictors for 90-day mortality were age, hypotension, closed head injury, max Abbreviated Injury Scale and hematocrit. There was an optimism-corrected C-index of 0.77. A calculator was created to predict a personalized mortality risk.

CONCLUSION

The incidence of spine trauma in elderly patients continues to increase. Previous publications described preexisting conditions that imply increased mortality, but ours is the first to develop a predictive calculator. Prospective research is planned to externally validate this model to better determine its predictive value and utility in the clinical setting.

Polytrauma in the Geriatric Population: Analysis of Outcomes for Surgically Treated Multiple Fractures with a Minimum 2 Years of Follow-Up

INTRODUCTION

This study analyzed the clinical and radiological outcomes of geriatric polytrauma patients who had multiple fractures surgically treated and a minimum of 2 years of follow-up.

METHODS

Eighty-six geriatric patients with polytrauma and multiple fractures which were surgically treated in orthopedics and who had a minimum of 2 years of follow-up were retrospectively analyzed. Patients' demographic characteristics, comorbidities, and follow-up time were recorded. The mechanism of injury, fracture type and location, Injury Severity Score (ISS), American Society of Anesthesiologists (ASA) score, duration of hospital stay, complications, and 1-year mortality were also recorded. Fracture union, implant failure, and refractures/misalignment were analyzed from radiographs.

RESULTS

There were 34 (39.5%) male and 52 (60.5%) female patients. Mean age was 73.5 years with an average follow-up time of 32.9 months. Patients had more low-energy traumas and more lower extremity, comminuted fractures. On the contrary, high-energy traumas and femur/pelvic fracture surgeries had higher associated mortality. The mean ISS score was 26.3. The most common ASA score was ASA 3 (75.8%). The most common clinical and radiological complications were prolonged wound drainage and implant failure. The total 1-year mortality rate was 22.1%. Patients with high ASA scores and patients with lower extremity fractures (femoral/pelvic fractures) also had significantly increased mortality rates. No significant relation was detected between mortality and ISS, fracture type, number of fractures, and duration of hospital stay.

CONCLUSION

Orthopedic surgeons must be alert about the possible complications of femoral fractures and comminuted fractures including pelvic girdle. Surgically treated, multifractured patients with high-energy trauma, advanced age, and high ASA scores are also at risk for mortality regardless of the ISS, comorbidities, and duration of hospital stay. Pulmonary thromboemboli must be kept in mind as a significant complication for mortality.

Factors Influencing Geriatric Orthopaedic Trauma Mortality

INTRODUCTION

This study aimed to: (1) evaluate the independent risk factors related to survival and mortality and (2) predict survival in geriatric orthopaedic trauma patients admitted to our institution's ICU as a Level 1 or 2 trauma activation.

METHODS

A retrospective review was performed on patients age >60, over a 10 year period, who were involved in a multi-trauma with orthopaedic injuries. Variables evaluated include: sex, age, Injury Severity Score (ISS), mechanism of injury, number and type of orthopaedic injury, anticoagulant use, comorbidities, length of stay in intensive care unit (ICU), type of ICU, ventilator use, vasopressors use, incidence of multiple organ dysfunction syndrome (MODS), number of surgeries, and 1-month and 6-month mortality. A Kaplan-Meier estimator and Cox proportional hazards analysis were used to predict and assess survival probability.

RESULTS

174 patients were included, with an average mortality of 47.7%. Deceased patients had a significantly greater age, ISS, vasopressor usage, ICU stay, incidence of MODF, incidence of genitourinary disease, anticoagulant usage, ventilator usage, number of orthopaedic surgeries, and orthopaedic injuries. The relative risk for mortality within the first month was significantly associated with increased age, ISS, high-energy trauma, length of ICU stay, MODS, psychiatric disease, and anticoagulant use. Patients with an ISS ≤30 were significantly more likely to survive than patients with an ISS of >30. Greater age, ISS, length of ICU stay, incidence of MODS, anticoagulant, and ventilator use were significantly predictive of lower survival rates. Mechanism of injury, number of orthopaedic surgeries and orthopaedic injuries, and type of orthopaedic injury were not found to be predictive of survival.

CONCLUSIONS

An ISS >30 at admission is strongly predictive of a lower probability of survival. Genitourinary disease was associated with increased mortality. Low age, ISS, length of stay in ICU, incidence of MODS, anticoagulant use, and ventilator use, are significantly predictive of survival. Number of orthopaedic surgeries, orthopaedic injuries, and type of orthopaedic injury were not found to be predictive of survival. These indications help us to better understand factors predictive of death among geriatric orthopaedic trauma patients, and improve the way we can diagnose and care for them.

Adipose browning response to burn trauma is impaired with aging

BACKGROUND

The incidence of burn injuries in older patients is dramatically increasing as the population of older people grows. Despite the increased demand for elderly burn care, the mechanisms that mediate increased morbidity and mortality in older trauma patients are unknown. We recently showed that a burn injury invokes white adipose tissue browning that leads to a substantially increased hypermetabolic response associated with poor outcomes. Therefore, the aim of this study was to determine the effect of age on the metabolic adipose response of browning after a burn injury.

METHOD

One hundred and seventy patients with burn injury admitted to the Ross Tilley Burn Centre were prospectively enrolled and grouped by age as older (≥50 years) and young (≤35 years). Adipose tissue and sera were collected and analyzed for browning markers and metabolic state via histology, gene expression, and resting energy expenditure assays.

RESULTS

We found that older patients with burn injury lacked the adipose browning response, as they showed significant reductions in uncoupling protein 1 (UCP1) expression. This failure of the browning response was associated with reduced whole-body metabolism and decreased survival in older patients with burn injury. Mechanistically, we found that the adipose of both aged patients after burn trauma and aged mice after a burn showed impairments in macrophage infiltration and IL-6, key immunological regulators of the browning process after a severe trauma.

CONCLUSION

Targeting pathways that activate the browning response represents a potential therapeutic approach to improve outcomes after burn trauma for elderly patients.

Trauma quality indicators: a way to identify attention points in the treatment of elderly trauma patients

PURPOSE

to trauma quality indicators as a tool to identify opportunities of improvement in elderly trauma patient's' treatment.

METHODS

prospective analysis of data collected between 2014-2015, and stored in the iTreg software (by Ecossistemas). Trauma victims, aged older than 60 years and trauma quality indicators were assessed, based on those supported by SBAIT in 2013: (F1) Acute subdural hematoma drainage after 4 hours from admission, in patients with GCS<9; (F2) emergency room transference without definitive airway and GCS <9; (F3) Re-intubation within 48 hours from extubation; (F4) Admission-laparotomy time greater than 60 min. in hemodynamically uinstable patients with abdominal bleeding; (F5) Unprogrammed reoperation; (F6) Laparotomy after 4 hours from admission; (F7) Unfixed femur diaphyseal fracture; (F8) Non-operative treatment for abdominal gunshot; (F9) Admission-tibial exposure fracture treatment time greater than 6 hours; (F10) Surgery after 24 from admission. The indicators, treatments, adverse effects and deaths were analyzed, using the SPSS software, and the chi-squared and Fisher tests were used to calculate the statistical relevance.

RESULTS

from the 92 cases, 36 (39,1%) had complications and 15 (16,3%) died. The adequate use of quality indicator's were substantially different among those who survived (was of 12%) compared to those who died (55,6%). The incidence of complications was of 77,8% (7/9) in patients with compromised indicators and 34,9% (28/83) in those without (p=0.017).

CONCLUSIONS

trauma quality indicators are directly related with the occurrence of complications and deaths, in elderly trauma patients.

The Impact of Age on Mortality in Patients in Extremis Undergoing Urgent Intervention

Trauma patients admitted without vital signs have little hope of survival even with extreme interventions. We performed this study to determine the effect of age on survival in patients in extremis undergoing urgent thoracotomy. The National Trauma Database was searched for patients presenting without a systolic blood pressure (0), a Glasgow Coma Scale score less than 8, and underwent an urgent thoracotomy. Mortality was determined for pediatric (younger than 16 years) and older patients (older than 60 years) and compared. Of 708 patients, 32 (4.5%) were pediatric and 57 (8.1%) were elderly. Pediatric mortality was 93.8 per cent (30) versus 95.6 per cent (646) for patients older than 16 years ( P = 0.981). Mortality in the older patients was 94.7 per cent (54) versus 95.5 per cent (622) in patients younger than 60 years ( P = 0.778). Race and blunt injury were independently associated with death. However, neither pediatric ( P = 0.418) nor older status ( P = 0.184) was predictive. Age does not significantly impact mortality in patients in extremis who undergo urgent thoracotomy. Age should not be a contributing factor in determining who should undergo more extreme maneuvers if they present as a reasonable candidate using other criteria.

Impact of Hormonal Protection in Blunt and Penetrating Trauma: A Retrospective Analysis of the National Trauma Data Bank

Over the last decade, gender and age-related hormonal status of trauma patients have been increasingly recognized as outcome factors. In the present study, we examine a large cohort of trauma patients to better appraise the effects of gender and age on patient outcome after blunt and penetrating trauma. We hypothesize that adult females are at lower risk for complications and mortality relative to adult males after both blunt and penetrating trauma. A retrospective analysis was conducted of the National Trauma Data Bank examining hormonally active females for advantages in survival and outcome after blunt and/or penetrating trauma. Over 1.4 million incident trauma cases were identified between 2002 and 2006. Multiple logistic regressions were calculated for associations between gender and outcome, stratified by injury type, age, comorbidity, Injury Severity Score (ISS), and complications. Risk factors associated with mortality in our multiple logistic regression analyses included: penetrating trauma (odds ratio [OR, 2.31; 95% confidence interval [CI], 2.27 to 2.36); adult male (OR, 1.45; 95% CI, 1.41 to 1.49); and ISS 15 or greater (OR, 14.68; 95% CI, 14.38 to 14.98). Adult females demonstrated a survival advantage over adult males (OR, 0.69; 95% CI, 0.67 to 0.71). Adult females with ISS less than 15 demonstrated a distinct survival advantage compared with adult males after both blunt and penetrating trauma. These results warrant further investigation into the role of sex hormones in trauma.

Trauma Recidivism Postdischarge Mortality: Important Differences Exist between the Adult and Geriatric Populations

Trauma recidivists are a high-risk patient population. The effects of recidivism on Geriatric trauma mortality have not been investigated. Our hypothesis is that trauma recidivism is associated with high postdischarge mortality after the initial index admission in both the geriatric and adult trauma populations. The trauma registry of our Level I trauma center was queried for patients evaluated between 2008 and 2012. Patients were stratified adult (18–64) and geriatric (≥65) groups and matched with mortality data from the National Death Index. Unique patients were identified and recidivists flagged. Statistical analysis was performed based on characteristics from the index admission using nonparametric tests, and Kaplan–Meier curves were plotted to examine postdischarge mortality after index admission for recidivists. A total of 8716 records met inclusion criteria; 800 recidivist records were identified representing 369 unique patients. Recidivists presented between 2 and 7 times. Recidivists were more likely to be male, required ICU admission and mechanical ventilation, had a longer median length of stay, were less likely to discharge home, and had a higher postdischarge mortality. Stratifying into adult and geriatric groups demonstrated significant differences in injury severity, injury patterns, length of stay, race, gender, mechanism, and postdischarge mortality. Recidivists demonstrated a higher postdischarge mortality in both groups with the geriatric group approaching 46 per cent. Trauma recidivists represent an at-risk group with significantly higher postdischarge mortality. Group characteristics differ significantly between the adult and geriatric recidivist populations. Further research is needed to identify modifiable risk factors in these populations to minimize risks of morbidity and mortality.

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.

Unsupervised Clustering Analysis Based on MODS Severity Identifies Four Distinct Organ Dysfunction Patterns in Severely Injured Blunt Trauma Patients

Purpose: We sought to identify a MODS score parameter that highly correlates with adverse outcomes and then use this parameter to test the hypothesis that multiple severity-based MODS clusters could be identified after blunt trauma. Methods: MOD score across days (D) 2-5 was subjected to Fuzzy C-means Clustering Analysis (FCM) followed by eight Clustering Validity Indices (CVI) to derive organ dysfunction patterns among 376 blunt trauma patients admitted to the intensive care unit (ICU) who survived to discharge. Thirty-one inflammation biomarkers were assayed (Luminex™) in serial blood samples (3 samples within the first 24 h and then daily up to D 5) and were analyzed using Two-Way ANOVA and Dynamic Network analysis (DyNA). Results: The FCM followed by CVI suggested four distinct clusters based on MOD score magnitude between D2 and D5. Distinct patterns of organ dysfunction emerged in each of the four clusters and exhibited statistically significant differences with regards to in-hospital outcomes. Interleukin (IL)-6, MCP-1, IL-10, IL-8, IP-10, sST2, and MIG were elevated differentially over time across the four clusters. DyNA identified remarkable differences in inflammatory network interconnectivity. Conclusion: These results suggest the existence of four distinct organ failure patterns based on MOD score magnitude in blunt trauma patients admitted to the ICU who survive to discharge.

Mortality profile of geriatric trauma at a level 1 trauma center

Background:

The management of geriatric trauma patients is challenging because of the altered physiology and co-existent medical conditions. To study the in-hospital mortality profile of geriatric trauma victims and the parameters associated with the mortality, we conducted this retrospective analysis.

Methods:

In a retrospective review of geriatric trauma admissions (above 60 years) over a 3-year period, we studied the association of age, gender, comorbidities, mechanism of injury (MOI), Glasgow coma score (GCS), injury severity score (ISS), systolic blood pressure, and hemoglobin (Hb) level on admission with hospital mortality. Univariate and Multivariable logistic regression was used to estimate odds and find independent associated parameters. P < 0.05 was considered as statistically significant.

Results:

Out of 881 patients, 208 (23.6%) patients died in hospital. The most common MOI was fall (53.3%) followed by motor vehicle collision (31.1%) and other mechanisms (14.5%). The in-hospital mortality was significantly higher and adjusted odds ratio (OR) for mortality were higher for male gender (2.11 [1.04–4.26]), higher ISS (6.75 [2.07–21.95] for ISS >30), low GCS (<8) (4.6 [2.35–8.97]), low Hb (<9) (1.68 [0.79–3.55]), hypotension on admission (32.42 [10.89–96.52]) as compared to other groups. Adjusted OR was 3.19 (1.55–6.56); 7.67 (1.10–53.49); 1.13 (0.08–17.12) for co-existent cardiovascular, renal, and hepatic comorbidities, respectively.

Conclusion:

Male gender, higher ISS, low GCS, low Hb, hypotension on admission, co-existent cardiovascular, renal and hepatic comorbidities are associated with increased mortality in geriatric trauma patients.

Using Trauma Triage Score to Risk-Stratify Inpatient Triage, Hospital Quality Measures, and Cost in Middle-Aged and Geriatric Orthopaedic Trauma Patients

OBJECTIVES

To investigate the efficacy of a novel geriatric trauma risk assessment tool [Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA)] designed to predict inpatient mortality to risk-stratify measures of hospital quality and cost of care in middle-aged and geriatric orthopaedic trauma patients.

DESIGN

Prospective cohort study.

SETTING

Academic medical center.

PATIENTS

One thousand five hundred ninety-two patients 55 years of age and older who were evaluated by orthopaedic surgery in the emergency department between October 1, 2014, and September 30, 2016.

INTERVENTION

Calculation of the inpatient mortality risk score (STTGMA) using each patient's demographics, injury severity, and functional status. Patients were stratified into minimal-, low-, moderate-, and high-risk cohort groups based on risk of <0.9%, 0.9%-1.9%, 1.9%-5%, and >5%.

MAIN OUTCOME MEASUREMENTS

Length of stay, complications, disposition, readmission, and cost.

RESULTS

One thousand two hundred seventy-eight patients (80.3%) sustained low-energy injuries and 314 patients (19.7%) sustained high-energy injuries. The average age was 73.8 ± 11.8 years. The mean length of hospital stay was 5.2 days with a significant difference between the STTGMA risk groups. This risk stratification between groups was also seen in complication rate, need for Intensive Care Unit/Step Down Unit care, percentage of patients discharged, and readmission within 30-days. The mean total cost of admission for the minimal-risk group was less than one-third that of the high-risk cohort.

CONCLUSIONS

The STTGMA tool is able to risk-stratify hospital quality outcome measures and cost. Thus, it is a valuable clinical tool for health care providers in identifying high-risk patients in efforts to continue to provide high-quality resource conscious care to orthopaedic trauma patients.

The evaluation of geriatric patients who presented with trauma to the emergency department

INTRODUCTION

Geriatric patients are subject to traumas more frequently due to age-related physiopathological changes. The objective of the study was to evaluate the demographic properties of geriatric patients who presented with trauma to the emergency department in addition to establishing the course of the diagnosis and treatment.

MATERIAL AND METHODS

Nine hundred and twelve geriatric patients who presented with trauma to the emergency department during one year were included in this retrospective study. Cause of the presentation, demographic properties, diseases, medications, sites of trauma, departments of consultations, departments that the patients were admitted to, discharge, mortality and morbidity rates were obtained from the folders of the subjects. The subjects were assigned to age groups 65-79 years old and over 80 years old.

RESULTS

60.4% (n = 551) of the 912 subjects were female, 39.6% (n = 361) were male and the mean age of the subjects was 77.16 (65-100). Falls were the most common cause (80.3%) of traumas, and the most frequently affected parts of the body were the extremities. The over 80 group was the most frequently consulted group (p = 0.01) and women were admitted more often to the hospital (p = 0.03). Of the patients who presented with trauma, 28.9% (n = 264) were hospitalized and 2% (n = 18) died. The most common causes of death of patients were femur fractures and intracranial hemorrhages.

CONCLUSIONS

Due to high mortality and morbidity, this geriatric patient group deserves a multidisciplinary approach beginning with the emergency departments.

Geriatric Polytrauma-Cardiovascular and Immunologic Response in a Murine Two-Hit Model of Trauma

BACKGROUND

The aims of the present study were to establish a clinically relevant two-hit model with trauma/hemorrhage followed by sepsis in older mice and investigate age-dependent cardiovascular and immunologic specificities under these conditions.

MATERIALS AND METHODS

In aged mice (12, 18, and 24 mo old), a femur fracture followed by hemorrhage was induced. After resuscitation, animals were monitored for 72 h before sepsis was induced. Vital signs were monitored during shock. Systemic interleukin (IL)-6 levels were measured daily. Expression of sarcoplasmic or endoplasmic reticulum calcium ATPase (SERCA) and IL-6 receptor were analyzed in heart, lung, and liver tissues.

RESULTS

After induction of shock, mean arterial pressure decreased significantly in all groups (12 mo, P < 0.001; 18 mo, P < 0.001; 24 mo, P = 0.013). Compared with younger animals, 24-mo old mice were not able to adequately compensate for hypovolemia by an increase of heart rate (P = 0.711). Expression of SERCA2 (P = 0.002) and IL-6 receptor on myocytes (P = 0.037), lung (P = 0.005), and liver (P = 0.009) tissues were also lowest in this group. Systemic IL-6 values showed the most distinct posttraumatic response in 24-mo-old mice (P = 0.016). Survival rate decreased significantly with increased age (P = 0.005).

CONCLUSIONS

The increased mortality rate in older animals was associated with a limited compensatory physiological response and a more distinct immunologic reaction after trauma and sepsis. A decreased SERCA2 expression and missing feedback loops due to a reduced density of organ bound immune receptors might represent possible explanations for the observed age-dependent differences.

Psychiatric Illness Is Common in Elderly Fracture Patients

OBJECTIVES

To (1) describe the prevalence of psychiatric illness in fracture patients ≥70 years of age and (2) investigate the association between psychiatric illness and complications requiring unplanned readmission in elderly patients.

DESIGN

Retrospective cohort study.

PATIENTS/PARTICIPANTS

One thousand one hundred eighty-six patients ≥70 years of age with surgically treated fractures and ≥1-month follow-up treated from 2012 to 2017.

INTERVENTION

None.

MAIN OUTCOME MEASURE

Complication requiring unplanned readmission.

RESULTS

Forty-four percent of patients ≥70 years of age have psychiatric comorbidities, and of those, 34% had >1 diagnosis. There was a higher rate of readmission among patients with psychiatric diagnosis compared with those without psychiatric diagnosis (35% vs. 21%, P < 0.001). There was a higher prevalence of psychiatric illness among patients 70 years of age or older compared with patients less than 70 years of age (44% vs. 39%, P = 0.007). Multivariate regression analysis controlling for age, sex, Charlson Comorbidity Index, dementia, delirium during admission, tobacco use, substance abuse, Injury Severity Score, fracture location, number of procedures, and number of fractures demonstrated an independent association between psychiatric illness and unplanned readmission (adjusted OR 1.54, 95% confidence interval, 1.15-2.07, P = 0.003).

CONCLUSIONS

Almost half of the elderly patients in the present cohort have psychiatric comorbidities. Furthermore, psychiatric illness is an independent predictor of unplanned readmission, which may have substantial consequences for recovery and cost of care. This emphasizes the need for more attention to these issues in geriatric patient populations and the need to identify means to influence the downstream consequences of these comorbidities.

Paradigm shift in geriatric fracture treatment

The number of geriatric patients is increasing. These patients exhibit specific characteristics, which influence the type of fracture care. Many patients have comorbidities, which make them more vulnerable to surgical procedures. The soft tissue envelope around the fracture often is compromised due to pre-existing diseases such as diabetes, chronic venous insufficiency or peripheral vascular disease. Bone mineral density has decreased, which enhances the risk of implant loosening. The goals of treatment differ from those, which are valid for younger adults. Primary goal is preserving independency of the elderly patient in his activities of daily life. Advantages and drawbacks of surgical procedures have to be balanced with those of conservative treatment. Fractures of the lower extremities will more often need surgical treatment than fractures of the upper extremities. Patient´s autonomy is best obtained by creating high stability in the fracture plane, which enables motion and weight-bearing. Second priority is prevention of general and local post-operative complications by the use of less invasive surgical procedures. Restoring anatomy and optimal function are less important goals. The implants, which are used, are inserted through small incisions, placed deep under the skin and use long anatomic or osseous corridors. Intramedullary devices have important advantages. This paradigm shift takes the special challenges and requirements of geriatric patients into account.

Delta Alert: Expanding Gerotrauma Criteria to Improve Patient Outcomes: A 2-Year Study

BACKGROUND/SIGNIFICANCE

Because of their decreased physical reserve and increased risk of complications, the geriatric trauma patient (GTP) population warrants heightened awareness by clinical staff.

PURPOSE

The purpose of this study is to determine whether the institution of a third-tier trauma protocol results in a change in GTP outcomes, complications, and mortality rates.

METHODS

Researchers conducted a retrospective review of 2 years of data from the trauma registry, hospital quality improvement audits, and patient charts to examine what, if any, patient outcomes were impacted by the institution of the expanded GTP protocol.

RESULTS

Sample homogeneity was determined. Emergency department (ED) length of stay and time to the operating room decreased in the protocol cohort. The rate of complications decreased from 16.4% preprotocol to 1.6% postprotocol. Discharge to home rates in the GTP population improved from 31% preprotocol to nearly 77% postimplementation of the protocol.

DISCUSSION

The expanded GTP protocol front loads evaluation and resuscitation to be consistent with ED trauma protocols already in place. By fast-tracking radiology and laboratory testing, patients injuries are identified and the appropriate consultations are initiated. Appropriate inpatient nursing unit placement is identified or treatment and discharge from the ED are expedited.

CONCLUSION

The expanded GTP protocol provided early and comprehensive evaluation and interventions for GTPs who fall outside of traditional trauma alert criteria. Patients spend less time in the ED and the hospital. Patients had decreased length of stay in the ED, less complications, and return to home rates showed significant improvement after the protocol was implemented.

Age and Number of Surgeries Increase Risk for Complications in Polytrauma Patients with Operative Maxillofacial Fractures

BACKGROUND

Poly-trauma patients often sustain complex head/neck injuries requiring prolonged hospitalizations and multiple operations. Few studies have evaluated the associated injury patterns and risk factors for poor clinical outcomes.

METHODS

Consecutive poly-trauma patients with operative maxillofacial fractures treated at a level 1 trauma medical center between 1995 and 2013 were evaluated. Concomitant head/neck injuries to identify potential injury patterns were numerated. Lastly, a multivariate analysis was performed to determine independent risk factors for complications during the acute hospitalization period.

RESULTS

Totally, 232 poly-trauma patients presented with operative maxillofacial fractures, while 38.8% of patients had a secondary maxillofacial fracture, 16.4% had intracranial hemorrhage, 23.7% had skull fractures, and 12.1% had spinal fractures. The rate of complication during admission was 28.3%. Multivariate analysis revealed advanced patient age and increased number of operations to predict the rate of complication. Patients requiring more than one operation had a 1.8-fold increase in complication rate (p<0.01) and older patients had a 4.5% increase in complication rate (p<0.05) for every year of increased age.

CONCLUSION

Poly-trauma patients have a high incidence of secondary maxillofacial fractures, concomitant head/neck injury, and inpatient complication rate. Knowledge of associated injury patterns can help increased awareness and can guide physician decision-making to avoid missed/delayed injuries.

Postdischarge Mortality after Geriatric Low-Level Falls: A Five-Year Analysis

Geriatric trauma patients with low-level falls often have multiple comorbidities and limited physiologic reserve. Our aim was to investigate postdischarge mortality in this population. We hypothesized that five-year mortality would be higher relative to other blunt mechanisms. The registry of our Level 1 trauma center was queried for patients evaluated between July 2008 and December 2012. Adult patients identified were matched with mortality data from 2008 to 2013 from the National Death Index. Low-level falls were identified by E Codes; other types of blunt trauma were based on registry classification. Patients with multiple admissions were excluded. Univariate analysis was performed using Fisher's exact and Wilcoxon tests. Kaplan-Meier curves were plotted to compare postdischarge mortality. Seven thousand nine hundred sixteen patients were evaluated, 35.1 per cent were females. Patients aged less than 65 years and penetrating trauma were excluded, yielding 1997 patients—63.7 per cent with low-level falls versus 36.3 per cent with other blunt traumas. Geriatric patients sustaining low-level falls were older, more likely female, had a higher inpatient mortality, and were less likely to return home at discharge. Injury severity score, hospital length of stay, and intensive care unit length of stay were similar. Survival analysis demonstrated increased postdischarge mortality in the low-level fall group with 25 per cent mortality at 120 days. Geriatric patients with other blunt trauma had a significantly lower postdischarge mortality. Geriatric patients injured in low-level falls have a higher inhospital mortality, are more likely to be functionally dependent on discharge, and have a high post-discharge mortality. Opportunities likely exist for injury prevention, consideration of palliative care, and postdischarge rehabilitation.

Wiser with Age? Increased Per-Surgeon Elderly Patient Volume is Associated with Lower Postinjury Complications

We hypothesize that higher elderly patient volume per trauma surgeon is associated with fewer clinical complications. This is a retrospective cohort study which included elderly patients admitted to trauma surgery service within a five-year period, from 2009 to 2013, at two Level I trauma centers in Florida. Trauma surgeons were stratified into three groups depending on patient volume. Primary outcomes were postinjury complications and in-hospital mortality, and secondary outcomes were hospital length of stay (LOS), intensive care unit LOS, and ventilator days. A total of 2379 elderly patients were included in this study. Elderly patient volume per surgeon did not significantly differ based on years in practice after fellowship (P = 0.88). The higher volume group had lower incidence of complications (15% complication rate, P = 0.02), compared with the average and low-volume group (18.1 and 21%, respectively), and had significantly lower rates of acute respiratory failure (P = 0.04) and acute renal failure (P = 0.004). In-hospital mortality was not affected by volume. Hospital LOS was decreased in the higher volume group (mean LOS 7.4 days, P < 0.001). There appears to be a relationship between elderly patient volume and outcome, independent of surgeon years of experience.

Is prescribed lower extremity weight-bearing status after geriatric lower extremity trauma associated with increased mortality?

OBJECTIVES

Evaluate whether mortality after discharge is elevated in geriatric fracture patients whose lower extremity weight-bearing is restricted.

DESIGN

Retrospective cohort study SETTING: Urban Level 1 trauma center PATIENTS/PARTICIPANTS: 1746 patients >65 years of age INTERVENTION: Post-operative lower extremity weight-bearing status MAIN OUTCOME MEASURE: Mortality, as determined by the Social Security Death Index RESULTS: Univariate analysis demonstrated that patients who were weight-bearing as tolerated on bilateral lower extremities (BLE) had significantly higher 5-year mortality compared to patients with restricted weight-bearing on one lower extremity and restricted weight-bearing on BLE (30%, 21% and 22% respectively, p < 0.001). Cox regression analysis controlling for variables including age, Charlson Comorbidity Index, Injury Severity Scale, combined UE/LE injury, injury mechanism (high vs low), sex, BMI and GCS demonstrated that, in comparison to patients who were weight bearing as tolerated on BLE, restricted weight-bearing on one lower extremity had a hazard ratio (HR) of 0.97 (95% confidence interval 0.78 to 1.20, p = 0.76) and restricted weight-bearing in BLE had a HR of 0.91 (95% confidence interval 0.60 to 1.36, p = 0.73).

CONCLUSIONS

In geriatric patients, prescribed weight-bearing status did not have a statistically significant association with mortality after discharge, when controlling for age, sex, body mass index, medical comorbidities, Injury Severity Scale (ISS), mechanism of injury, nonoperative treatment and admission GCS. This remained true in when the analysis was restricted to operative injuries only.

Retrospective evaluation of 140 dogs involved in road traffic accidents

This study has retrospectively reviewed the medical records of 140 dogs sustaining road traffic accident (RTA), and has examined the population characteristics, medical history, injury type, physical examination, emergency laboratory tests and radiography findings, the animal trauma triage (ATT) score, the length of hospitalisation, the complications and the outcome. The survival rate was 83.2 per cent. Younger dogs sustained more frequently lung contusions and limb fractures, while larger dogs more frequently suffered limb fractures, and smaller dogs and older ones sustained more frequently pelvic fractures and sacroiliac luxation (P<0.05 for all). Dogs sustaining orthopaedic injuries required longer hospitalisation (P<0.001). The survival rates of non-ambulatory dogs (P<0.001) and those with neurological abnormalities (P<0.001), abnormal body temperature (P=0.001), hyperglycaemia (P=0.026) or hypoproteinaemia (P=0.04) at presentation were lower compared with those in which these were absent. The number of injured body systems was significantly (P<0.001) and positively associated with death. Dogs surviving RTA to presentation to the hospital have a good prognosis for survival to discharge. Older age, and high ATT score, abnormal body temperature, neurological deficits, hyperglycaemia and hypoproteinaemia at presentation, and occurrence of multiorgan trauma are negative prognostic indicators in such dogs.

Trends in Patient Care for Traumatic Spinal Injuries in the United States: A National Inpatient Sample Study of the Correlations With Patient Outcomes From 2001 to 2012

STUDY DESIGN

A retrospective database review.

OBJECTIVE

The aim of this study was to examine whether patient characteristics, distribution of care, and patient outcomes for spinal cord injury (SCI) in the United States have changed between 2001 and 2012.

SUMMARY OF BACKGROUND DATA

Although patient outcomes after cranial injury are better at high-volume centers with specialized, multidisciplinary teams, similar assessments have not been done for spinal injuries.

METHODS

We retrospectively reviewed the National and Nationwide Inpatient Samples for the years 2001, 2002, 2011, and 2012 to identify patients with spinal fracture with or without SCI. The demographic characteristics of the patient cohort, clinical course, hospital characteristics, interhospital transfer, and disposition were statistically analyzed relative to patient mortality, total hospital costs, and length of stay. How these data changed over this 11-year period was also evaluated.

RESULTS

A total of 159,875 cases were identified, with 141,737 fractures without SCI and 18,138 SCIs with or without fracture. There was a statistically significant decrease in the percentage of patients transferred with spine injury from 4.2% to 3.4% (P < 0.001) from the early years to the later years and in patient transfers for SCIs (8.1% vs. 6.5%, P < 0.001). Interestingly, the overall mortality rate (3.5% vs. 3.6%) remained unchanged (P = 0.679), but mortality from SCI increased (6.6-7.4%, P = 0.021).

CONCLUSION

From 2002 to 2012, the rate of interhospital transfer of spinal injury patients declined, while the mortality rate for patients with SCI increased. Interestingly, there was an increase in transfers after spinal surgery at the index hospital. The decentralization of spine care may be responsible for the increase in mortality.

Differences in Injury Pattern and Mortality between Hong Kong Elderly and Younger Patients

Background

The rapidly aging population in Hong Kong is causing an impact on our health care system. In Hong Kong, 16.5% of emergency department trauma patients are aged ≥65 years.

Objective

We aim to compare factors associated with trauma and differences in trauma mortality between elderly (≥65 years) and younger adult patients (15 to 64 years) in Hong Kong.

Methods

A retrospective observational study was performed using trauma registry data from the Prince of Wales Hospital, a 1200–bed acute hospital which is a regional trauma centre.

Results

A total of 2172 patients (331 [15.2%] elderly and 1841 [84.8%] younger) were included. Male patients predominated in the younger adult group but not in the elderly group. Compared with younger patients, elderly patients had more low falls and pedestrian-vehicle crashes and sustained injuries to the head, neck and extremities more frequently. The odds ratio (OR) for death following trauma was 5.5 in the elderly group (95% confidence interval [CI] 3.4–8.9, p>0.0001). Mortality rates increased progressively with age (p>0.0001) and were higher in the elderly at all levels of Injury Severity Score (ISS). Age ≥65 years independently predicted mortality (OR=5.7, 95% CI 3.5–9.3, p>0.0001). The elderly had a higher co-morbidity rate (58.6% vs. 14.1%; p>0.01). There was a lower proportion of trauma call activations for the elderly group (38.6% vs. 53.3%; p>0.01).

Conclusion

Elderly trauma patients differ from younger adult trauma patients in injury patterns, modes of presentation of significant injuries and mortality rates. In particular, the high mortality of elderly trauma requires renewed prevention efforts and aggressive trauma care to maximise the chance of survival.

Survivorship After High-Energy Geriatric Trauma

OBJECTIVES

To evaluate in-hospital, 1-year, and 5-year survivorship of geriatric patients after high-energy trauma, to compare survivorship of geriatric patients who sustained high-energy trauma with that of those who sustained low-energy trauma, and to identify predictors for mortality.

DESIGN

Retrospective.

SETTING

Urban Level I trauma center.

PATIENTS

Study group of 1849 patients with high-energy trauma and comparison group of 761 patients with low-energy trauma.

INTERVENTION

Each patient was observed from the time of index admission through the end of the study period or until death or readmission.

MAIN OUTCOME MEASUREMENT

Long-term survivorship based on the Social Security Death Index.

RESULTS

Survivorship between patients with high-energy and low-energy injuries was statistically significant. Among patients who sustained high-energy injuries, in-hospital mortality was 8%, 1-year mortality was 15%, and 5-year mortality was 25%. Among patients who sustained low-energy injuries, in-hospital mortality was 3%, 1-year mortality was 23%, and 5-year mortality was 40%. Low-energy mechanism of injury was an independent predictor for 1-year and 5-year mortality, even when controlling for Charlson Comorbidity Index (CCI), Injury Severity Score (ISS), age, sex, body mass index (BMI), and admission Glasgow Coma Scale (GCS) score.

CONCLUSIONS

Geriatric patients with high-energy injuries and those with low-energy injuries seem to represent different patient populations, and low-energy mechanism seems to be a marker for frailty. High-energy mechanism was associated with lower long-term mortality rates, even when controlling for CCI, ISS, age, sex, BMI and admission GCS score.

The G60 Trauma Center: A Future Consideration?

With a considerably increasing elderly population, we sought to determine whether the volume of elderly trauma patients treated impacted outcomes at two different Level I trauma centers. This is a retrospective review of all elderly patients (>60 years) at two state-verified Level I trauma centers over the past five years. The elderly trauma center (ETC) saw a greater proportion (52%) of elderly patients than the reference trauma center (30%, TC). Demographic and clinical characteristics were abstracted and stratified into ETC and TC groups for comparison. Primary outcomes were overall postinjury complication and mortality rates, as well as death after major complication (failure to rescue). ETC patients were older (78.6 vs 70.5), more likely to be admitted with severe head injuries (head abbreviated injury score ≥ 3, 50.0% vs 32%), had a greater overall injury burden (injury severity score > 16 41.4% vs 21.1%), and required intensive care unit admission (81.3% vs 64%) than the TC group. Need for operative intervention, mechanism of injury, and comorbidities were similar between the two groups. Overall complications were higher in trauma patients admitted to the TC (21.9% vs 14.3%), as well as failure to rescue (4.0% vs 1.8%). Adjusting for confounding factors, ETC had significantly lower chance of developing a postinjury complication (adjusted odds ratios [AOR] = 0.4, 95% confidence interval [CI] = [0.3, 0.5]), failure to rescue (AOR = 0.3, 95% CI = [0.1, 0.5]), and overall mortality (AOR = 0.3, 95% CI = [0.2, 0.4]). Improved outcomes were demonstrated in the Level I center treating a higher proportion of elderly patients. Exact etiology of these benefits should be determined for quality improvement in care of the injured geriatric patient.

Risk factors associated with in-hospital mortality in elderly patients admitted to a regional trauma center after sustaining a fall

BACKGROUND AND AIMS

Falls are a significant cause of mortality in the elderly patients. Despite this, the literature on in-hospital mortality related to elderly falls remains sparse. Our study aims to determine the risk factors associated with in-hospital mortality in elderly patients admitted to a regional trauma center after sustaining a fall.

METHODS

All elderly case records with fall-related injuries between 2003 and 2013 were retrospectively analyzed for demographic characteristics, injury severities, comorbidity factors and clinical outcomes. Logistic regression analysis was used to examine the risk factors associated with in-hospital mortality.

RESULTS

In total, 1026 elderly patients with fall-related injuries were included in the study. The average age of patients was 80.94 ± 8.16 years. Seventy seven percent of the patients had at least one comorbid condition. Majority of the falls occurred at home. More than half of the patients fell from ground level. Overall, the in-hospital mortality rate was 16 %. Head injury constituted the most common injury sustained in patients who died (77 %). In addition to age, ISS, GCS, ICU admission and anemia were significantly (P < 0.05) associated with in-hospital deaths in elderly fall patients.

CONCLUSION

Ground-level falls in the elderly can be devastating and carry a significant mortality rate. Elderly patients with anemia were two times more likely to die in the hospital after sustaining a fall in our study population. Increased focus on anemia which is often underappreciated in elderly fall patients can be beneficial in improving outcomes and reducing in-hospital mortality.

Road Crashes in Older Persons and the Use of Comorbidity Polypharmacy Score in an Asian Population

Introduction: Age-related physiological changes predispose older road users to higher mortality from traffic crashes. We aimed to describe the injury epidemiology of these patients, and explore the association between the comorbidity polypharmacy score (CPS) and outcomes. Materials and Methods: This retrospective study utilised data from the Trauma Registry in the National University Hospital, Singapore, between January 2011 and December 2014. Patients involved in traffic crashes aged 45 years and above with injury severity scores (ISS) of 9 and higher were included. Results: There were 432 patients; median age was 58 (interquartile range, 51 to 65.5) years with predominance of male patients (82.2%) and Chinese ethnicity (66%). Overall mortality was 9.95%, with lower odds associated with higher Glasgow Coma Scale (odds ratio [OR] 0.73; 95% confidence interval [CI], 0.65 to 0.81, P <0.001), higher diastolic blood pressure (OR 0.98; 95% CI, 0.97 to 1.00, P = 0.031), and lower ISS of 9 to 15 (OR 0.10; 95% CI, 0.02 to 0.43, P = 0.002). The need for blood products was associated with higher mortality (OR 7.62; 95% CI, 2.67 to 21.7, P <0.001). CPS did not predict mortality. Independent predictors of discharge venue included length of stay, tier of injury and CPS group. Moderate CPS was statistically significant for nursing home placement (OR 10.7; 95% CI, 2.33 to 49.6, P = 0.002) but not for rehabilitation facility. Conclusion: CPS score is useful in predicting discharge to a nursing home facility for older patients with traffic crashes. Further larger studies involving other trauma types in the Asian population are needed to evaluate its utility. Key words: Elderly, Motor vehicle crashes, Trauma severity indices

Global burden of road traffic accidents in older adults: A systematic review and meta-regression analysis

PURPOSE OF THE STUDY

This study aims to estimate the burden of road traffic accidents and death among older adults.

DESIGN AND METHODS

A systematic literature review was conducted on 10 electronic databases for articles describing Road Traffic Accident(RTA) mortality in older adults until September 2016. A random-effects meta-regression analyses was conducted to estimate the pooled rates of road traffic accidents and death.

RESULTS

A total 5018 studies were identified and 23 studies were included. Most of the reported older adults were aged between 60 and 74 years, with majority being male gender and sustained minor trauma due to Motor-Vehicle Collision (MVC). The overall pooled mortality rate was 14% (95% Confidence Interval, CI: 11%, 16%), with higher mortality rates in studies conducted in North America (15%, 95% CI: 12%, 18%) and older adults admitted to trauma centers (17%, 95% CI: 14%, 21%). Secondary analysis showed that the very elderly adults (aged >75years) and pedestrians had higher odds of mortality death (Odds Ratio, OR: 2.05, 95% CI: 1.25, 3.38; OR: 2.08, 95% CI: 1.63, 2.66, respectively).

IMPLICATION

A new comprehensive trauma management guidelines tailored to older adults should be established in low and middle-income countries where such guidelines are still lacking.

Assessment of resuscitation as measured by markers of metabolic acidosis and features of injury

AIMS

The best time for definitive orthopaedic care is often unclear in patients with multiple injuries. The objective of this study was make a prospective assessment of the safety of our early appropriate care (EAC) strategy and to evaluate the potential benefit of additional laboratory data to determine readiness for surgery.

PATIENTS AND METHODS

A cohort of 335 patients with fractures of the pelvis, acetabulum, femur, or spine were included. Patients underwent definitive fixation within 36 hours if one of the following three parameters were met: lactate < 4.0 mmol/L; pH ≥ 7.25; or base excess (BE) ≥ -5.5 mmol/L. If all three parameters were met, resuscitation was designated full protocol resuscitation (FPR). If less than all three parameters were met, it was designated an incomplete protocol resuscitation (IPR). Complications were assessed by an independent adjudication committee and included infection; sepsis; PE/DVT; organ failure; pneumonia, and acute respiratory distress syndrome (ARDS).

RESULTS

In total, 66 patients (19.7%) developed 90 complications. An historical cohort of 1441 patients had a complication rate of 22.1%. The complication rate for patients with only one EAC parameter at the point of protocol was 34.3%, which was higher than other groups (p = 0.041). Patients who had IPR did not have significantly more complications (31.8%) than those who had FPR (22.6%; p = 0.078). Regression analysis showed male gender and injury severity score to be independent predictors of complications.

CONCLUSIONS

This study highlights important trends in the IPR and FPR groups, suggesting that differences in resuscitation parameters may guide care in certain patients; further study is, however, required. We advocate the use of the existing protocol, while research is continued for high-risk subgroups. Cite this article: Bone Joint J 2017;99-B:122-7.

Fibrinogen degradation product levels on arrival for trauma patients requiring a transfusion even without head injury

BACKGROUND

There have been few reports on the clinical significance of the fibrinogen degradation product (FDP) level in trauma patients with and without head injury. We retrospectively analyzed trauma patients with or without head injury to investigate the clinical significance of the FDP level.

METHODS

From April 2013 to June 2015, a medical chart review was retrospectively performed for all patients with trauma. The exclusion criteria included patients who did not receive a transfusion. The patients were divided into two groups: a FDP>100 group, which included patients who had an FDP level on arrival over 100 ng/mL, and a FDP≤100 group.

RESULTS

The ratio of open fractures and the prothrombin ratio in the FDP>100 group were significantly smaller than those observed in the FDP≤100 group. The average age, ratio of blunt injury, Injury Severity Score (ISS), volume of transfusion and mortality ratio in the FDP>100 group were significantly greater than those in the FDP≤100 group. There was a weakly positive correlation between the FDP level and ISS (R=0.35, P=0.002), but it was not associated with the transfusion volume. The results of an analysis excluding patients with head injury showed a similar tendency.

CONCLUSION

The FDP levels may be a useful biochemical parameter for the initial evaluation of the severity of trauma and mortality even in blunt traumatized patients without head injury or with stable vital signs.

Validation of the Shock Index, Modified Shock Index, and Age Shock Index for Predicting Mortality of Geriatric Trauma Patients in Emergency Departments

The shock index (SI), modified shock index (MSI), and age multiplied by SI (Age SI) are used to assess the severity and predict the mortality of trauma patients, but their validity for geriatric patients is controversial. The purpose of this investigation was to assess predictive value of the SI, MSI, and Age SI for geriatric trauma patients. We used the Emergency Department-based Injury In-depth Surveillance (EDIIS), which has data from 20 EDs across Korea. Patients older than 65 years who had traumatic injuries from January 2008 to December 2013 were enrolled. We compared in-hospital and ED mortality of groups categorized as stable and unstable according to indexes. We also assessed their predictive power of each index by calculating the area under the each receiver operating characteristic (AUROC) curve. A total of 45,880 cases were included. The percentage of cases classified as unstable was greater among non-survivors than survivors for the SI (36.6% vs. 1.8%, P < 0.001), the MSI (38.6% vs. 2.2%, P < 0.001), and the Age SI (69.4% vs. 21.3%, P < 0.001). Non-survivors had higher median values than survivors on the SI (0.84 vs. 0.57, P < 0.001), MSI (0.79 vs. 1.14, P < 0.001), and Age SI (64.0 vs. 41.5, P < 0.001). The predictive power of the Age SI for in-hospital mortality was higher than SI (AUROC: 0.740 vs. 0.674, P < 0.001) or MSI (0.682, P < 0.001) in geriatric trauma patients.

Evaluation of major trauma in elderly patients - a single trauma center analysis

BACKGROUND

The objective of the study was to gather information about elderly major trauma patients admitted to one particular Slovenian trauma centre in Celje and examine this group of polytrauma patients, specifically with respect to mechanisms of injury, injury severity and distribution of injuries. Further on, to identify morbidity and mortality rates and compare these to the younger population and, finally, to determine the factors that have the most impact on treatment results.

METHODS

The study gathered and evaluated data of 532 patients included in the Trauma Register DGU® of the German Trauma Society (TR-DGU) during a 10-year period and two distinct groups of patients were established, separated on account of age as older or younger than 65 years. The differences between these two groups were analyzed with respect to demographics, comorbidities, preclinical management, injury patterns, relevant clinical and laboratory findings. Furthermore, differences between deceased and surviving elderly patients were also analyzed.

RESULTS

The majority of elderly patients suffered from a blunt mechanism of trauma (96.6%) and of these simple falls represented 47.9% within this injury mechanism. There were two body regions, which were most frequently represented, namely head and thorax injuries, accounting for 54.7% each. Complications were more frequent among the elderly, with sepsis being present in 29.9% and multiple organ failure (MOF) in 19.7% of cases. Cardiovascular failure was also high in both the elderly and young, accounting for 45.3% of the elderly and 31.3% of the younger population. The in-hospital mortality rate for the elderly group was 25.6% and was significantly higher compared to the younger counterparts (14.7%). Low fall mechanism of injury, coma and the new injury severity score (NISS) were statistically important factors for the mortality of seriously injured elderly patients during the acute phase of treatment.

CONCLUSIONS

Despite advances in care, morbidity and mortality in elderly patients after major trauma remains considerably higher than in younger populations with head injuries accounting for the majority of fatalities. The elderly patient population in this study mostly suffered from blunt mechanisms of injury, with simple falls representing a high proportion of injury mechanisms. Generally, the injury severity scale (ISS) in the elderly is not statistically higher than with the younger population. Likewise, the distribution of injuries according to body regions is also similar; however, the elderly are more prone to complications (e. g. sepsis and MOF), which is likely due to a lower physiological reserves.

[Elective and acute procedures in trauma surgery. Complications requiring revision]

BACKGROUND

Using data between 2010 and 31 March 2012, a cohort study concerning complications of all discharged patients who had undergone surgery was performed.

PATIENTS AND METHODS

In our detailed analysis, we defined two groups out of the 5,248 cases: an acute trauma patient group (n = 3,942) and an elective patient group (n = 1,306). Complications were divided into the following groups: (1) technical complications (failure of the implant, poor indication, instability or non-union), (2) local complication (hematoma or delayed wound healing), and (3) infection.

RESULTS

In 4.4% of patients (n = 233), treatment was delayed because of a complication. In 2.3% (n = 123), a technical complication was observed, followed by local complications in 1.3% [e.g., hematoma 0.6%, other wound healing disturbance (0.6%)]. In the elective surgery group, the percentage of complications needing revision (3.1%) was significantly lower compared to the trauma surgery group (4.9%). The patient's age for the non-complicated surgery group was significantly lower (54 vs. 63 years) and length of hospital stay (6.7 days longer) was significantly higher in patients with complications. Risk factors such as smoking were significantly more frequent in patients with complications (9% vs. 18.5%).

CONCLUSION

Recording and evaluating of complications in surgery plays a major role for quality control. Certain factors (e.g., comorbidity and the age of the patient) cannot be influenced, but complications caused by technical problems could theoretically be avoided. Especially these cases must be analyzed in detail to reduce the percentage of complications requiring revision.
