Spinal cord injuries related to cervical spine fractures in elderly patients: factors affecting mortality

Epidemiology of demographic, clinical characteristics and hospital course of patients with spinal cord injury associated with vertebral fracture in a large private health care system in the United States

Objectives: To evaluate the demographics, clinical characteristics, hospital course, and factors associated with outcomes in patients with spinal cord injury associated with vertebral fracture (SCI-VF).Design: Retrospective analysis of data collected from electronic health record.Setting: A large for-profit United States health care system.Participants: 2219 inpatients with SCI-VF between 2014 and 2020 identified using International Classification of Disease codes.Main Outcome Measure: In-hospital mortality, and disposition (home vs. no-home discharge) after hospitalization.Results: The mean age of patients admitted with a diagnosis of SCI-VF was 54.80 ± 20.85 years with 68.27% identified as male. The cervical spine was the most prevalent site of fracture, displaced vertebral fracture was the most common radiographic diagnosis, and the majority of injuries were classified as incomplete. 836 (37.67% of all 2219) patients were discharged home and had a shorter length of stay (7.56 ± 13.58 days) when compared to the average of the total study population (11.56 ± 19.2 days). The most common hospital-acquired complication (HAC) was falls (n = 259, 11.67%). Characteristics associated with in-hospital mortality in the 96 patients (6.94% of 1,383 patients with no-home discharge) included initial respiratory failure, ICU stay, increased medical comorbidity index value, insulin use, and presence of cardiovascular, pulmonary, and gastrointestinal HACs.Conclusions: A large observational study of patients with SCI-VF can add to the knowledge of SCI characteristics in the U.S. population. Recognizing the common hospital-acquired conditions and clinical characteristics associated with increased in-hospital mortality can be helpful to improve the care of patients with SCI-VF.

Predictors of early mortality following surgical or nonsurgical treatment of subaxial cervical spine fractures: a retrospective nationwide registry study

BACKGROUND

Traumatic subaxial cervical spine fractures are a significant public health concern due to their association with spinal cord injuries (SCI). Despite being mostly caused by low-energy trauma, these fractures significantly contribute to morbidity and mortality. Currently, research regarding early mortality based on the choice of treatment following these fractures is limited. Identifying predictors of early mortality may aid in postoperative patient monitoring and improve outcomes.

PURPOSE

This study aimed to identify predictors of 30-days, 90-days, and 1-year mortality in adults treated for subaxial fractures.

STUDY DESIGN

A retrospective review of the nationwide Swedish Fracture Register (SFR).

PATIENT SAMPLE

All adult patients in the SFR who underwent treatment for a subaxial cervical fracture (n = 1,963).

OUTCOME MEASURES

Analyzed variables included age, sex, injury mechanism, neurological function, fracture characteristics, and treatment type. The primary endpoints were 30-days, 90-days, and 1-year mortality.

METHODS

About 1,963 patients in the SFR, treated for subaxial cervical fractures between 2013 and 2021, were analyzed. Surgical procedures included anterior, posterior, or anteroposterior approaches. Nonsurgical treatment included collar treatment or medical examinations without intervention. Stepwise regression and Cox regression analysis were used to determine predictors. Model performance was tested using the area under the receiver operating characteristic curve (AUC).

RESULTS

A total of 620 patients underwent surgery and 1,343 received nonsurgical treatment. Surgical cases had primarily translation fractures, with 323 (52%) displaying no neurological deficits. Mortality rates at 30 days, 90 days, and 1 year were 22/620 (3.5%), 35/620 (5.6%), and 53/620 (8.5%), respectively. Age and SCI were predictors of mortality. Nonsurgically treated patients mostly had compression fracture, with 1,214 (90%) experiencing no neurological deficits. Mortality rates at 30 days, 90 days, and 1 year were 41/1,343 (3.1%), 71/1,343 (5.3%), and 118/1,343 (8.7%). Age, male sex, SCI and fractures occurring at the C3 or C6 levels were predictors of mortality. An intact neurological function was a positive predictor of survival among nonsurgically treated patients (AUC >0.78).

CONCLUSIONS

Age and SCI emerged as significant predictors of early mortality in both surgically and nonsurgically treated patients. An intact neurological function served as a protective factor against early mortality in nonsurgically treated patients. Fractures at C3 or C6 vertebrae may impact mortality.

Identifying factors predicting outcomes after major trauma in older patients: Prognostic systematic review and meta-analysis

INTRODUCTION

Trauma is the most common cause of morbidity and mortality in older people, and it is important to determine the predictors of outcomes after major trauma in older people.

METHODS

MEDLINE, Embase, and Web of Science were searched, and manual search of relevant papers since 1987 to February 2023 was performed. Random-effects meta-analyses were performed. The primary outcome of interest was mortality, and secondary outcomes were medical complications, length of stay, discharge destination, readmission, and intensive care requirement.

RESULTS

Among 6,064 studies in the search strategy, 136 studies qualified the inclusion criteria. Forty-three factors, ranging from demographics to patient factors, admission measurements, and injury factors, were identified as potential predictors. Mortality was the commonest outcome investigated, and increasing age was associated with increased risk of in-hospital mortality (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.03-1.07) along with male sex (OR, 1.40; 95% CI, 1.24-1.59). Comorbidities of heart disease (OR, 2.59; 95% CI, 1.41-4.77), renal disease (OR, 2.52; 95% CI, 1.79-3.56), respiratory disease (OR, 1.40; 95% CI, 1.09-1.81), diabetes (OR, 1.35; 95% CI, 1.03-1.77), and neurological disease (OR, 1.42; 95% CI, 0.93-2.18) were also associated with increased in-hospital mortality risk. Each point increase in the Glasgow Coma Scale lowered the risk of in-hospital mortality (OR, 0.85; 95% CI, 0.76-0.95), while each point increase in Injury Severity Score increased the risk of in-hospital mortality (OR, 1.07; 95% CI, 1.04-1.09). There were limited studies and substantial variability in secondary outcome predictors; however, medical comorbidities, frailty, and premorbid living condition appeared predictive for those outcomes.

CONCLUSION

This review was able to identify potential predictors for older trauma patients. The identification of these factors allows for future development of risk stratification tools for clinicians.

Prognostic impact of respiratory dysfunction in elderly patients with cervical spinal cord injury and/or fractures: a multicenter survey

PURPOSE

To investigate the impact of early post-injury respiratory dysfunction for neurological and ambulatory ability recovery in patients with cervical spinal cord injury (SCI) and/or fractures.

METHODS

We included 1,353 elderly patients with SCI and/or fractures from 78 institutions in Japan. Patients who required early tracheostomy and ventilator management and those who developed respiratory complications were included in the respiratory dysfunction group, which was further classified into mild and severe respiratory groups based on respiratory weaning management. Patient characteristics, laboratory data, neurological impairment scale scores, complications at injury, and surgical treatment were evaluated. We performed a propensity score-matched analysis to compare neurological outcomes and mobility between groups.

RESULTS

Overall, 104 patients (7.8%) had impaired respiratory function. In propensity score-matched analysis, the respiratory dysfunction group had a lower home discharge and ambulation rates (p = 0.018, p = 0.001, respectively), and higher rate of severe paralysis (p < 0.001) at discharge. At the final follow-up, the respiratory dysfunction group had a lower ambulation rate (p = 0.004) and higher rate of severe paralysis (p < 0.001). Twenty-six patients with severe disability required respiratory management for up to 6 months post-injury and died of respiratory complications. The mild and severe respiratory dysfunction groups had a high percentage of severe paraplegic cases with low ambulatory ability; there was no significant difference between them. The severe respiratory dysfunction group tended to have a poorer prognosis.

CONCLUSION

Respiratory dysfunction in elderly patients with SCI and/or cervical fracture in the early post-injury period reflects the severity of the condition and may be a useful prognostic predictor.

In-hospital mortality rate in subaxial cervical spinal cord injury patients: a systematic review and meta-analysis

PURPOSE

To determine existing trends concerning in-hospital mortality in patients with traumatic subaxial cervical spinal cord injury (SCI) over the last four decades.

METHODS

We searched MEDLINE and EMBASE to assess the role of the following factors on in-hospital mortality over the last four decades: neurological deficit, age, surgical decompression, use of computed tomography (CT) and magnetic resonance imaging (MRI), use of methylprednisolone in the acute post-injury period, and study location (developing versus developed countries).

RESULTS

Among 3333 papers after deduplication, 21 studies met the eligibility criteria. The mortality rate was 17.88% [95% confidence interval (CI): 12.9-22.87%]. No significant trend in mortality rate was observed over the 42-year period (meta-regression coefficient = 0.317; p = 0.372). Subgroup analysis revealed no significant association between acute subaxial cervical SCI-related mortality when stratified by use of surgery, administration of methylprednisolone, use of MRI and CT imaging, study design (prospective versus retrospective study), and study location. The mortality rate was significantly higher in complete SCI (20.66%, p = 0.002) and American Spinal Injury Association impairment scale (AIS) A (20.57%) and B (9.28%) (p = 0.028).

CONCLUSION

A very low level of evidence showed that in-hospital mortality in patients with traumatic subaxial cervical SCI did not decrease over the last four decades despite diagnostic and therapeutic advancements. The overall acute mortality rate following subaxial cervical SCI is 17.88%. We recommend reporting a stratified mortality rate according to key factors such as treatment paradigms, age, and severity of injury in future studies.

Geriatric spine fractures - Demography, changing trends, challenges and special considerations: A narrative review

The aim of this manuscript was to summarize the demography and changing trends of geriatric spinal injuries and to enumerate the challenges and special considerations in the care of geriatric spinal injuries. PubMed, Scopus and Embase databases were searched for literature on geriatric spine fractures using MeSH terms 'aged', 'aged, 80 and over', 'elderly', 'spinal fracture/epidemiology', spinal fracture/therapy∗' and keywords pertaining to the same. The search results were screened for appropriate articles and reviewed. There is a high community prevalence of elderly vertebral fractures ranging from 18% to as high as 51%. The proportion of older patients among the spinal injured is rising as well. There is a higher chance of missing spinal injuries in the elderly and clinical guidelines may not be applicable to this patient group. Classification and surgical treatment are different from younger adult counterparts as the elderly osteoporotic spine behaves differently biomechanically. There is a high incidence of respiratory complications both for surgically and conservatively managed groups. Older age generally is associated with a higher complication rate including mortality.

Prognosis and conditional nomogram of cervical spine fracture in patients with severe spinal cord injury: a multicenter retrospective study

INTRODUCTION

Cervical spine fractures with severe spinal cord injury (SCI) are common following cervical spine trauma and are associated with a high mortality rate. Understanding the mortality patterns of patients with cervical spine fractures and severe SCI can offer valuable evidence to surgeons and family members who are required to make critical healthcare decisions. The authors aimed to evaluate the instantaneous death risk and conditional survival (CS) of such patients and developed conditional nomograms to account for different periods of survivors and predict the survival rates.

METHODS

Their instantaneous death risks were calculated using the hazard function, and the Kaplan-Meier method was used to evaluate the survival rates. Cox regression was used to choose the variables for the construction of the nomograms. The area under the receiver operating characteristic curve and calibration plots were used to validate the performance of the nomograms.

RESULTS

The authors finally included 450 patients with cervical spine fractures and severe SCI using propensity score matching. The instantaneous death risk was the highest during the first 12 months after injury. Surgical treatment can help decrease the instantaneous death risk quickly, especially in early-term surgery. The 5-year CS increased constantly from 73.3% at baseline to 88.0% after 2 years of survival. Conditional nomograms were constructed at baseline and in those who survived for 6 and 12 months. The area under the receiver operating characteristic curve and calibration curves indicated that the nomograms had a good performance.

CONCLUSION

Their results improve our understanding of the instantaneous death risk of patients in different periods following injury. CS demonstrated the exact survival rate among medium-term and long-term survivors. Conditional nomograms are suitable for different survival periods in predicting the probability of survival. Conditional nomograms help in understanding the prognosis and improve the shared decision-making approaches.

Anterior cervical discectomy and fusion with plate versus posterior screw fixation after traumatic subaxial fractures in octogenarians: complications and outcomes with a 2-year follow-up

INTRODUCTION

Surgical intervention for management of spinal instability after traumatic subaxial fractures in octogenarians requires a clear consensus on optimal treatments. This study aimed to provide a guide for more efficient management through comparison and assessment of clinical outcomes and complications of anterior cervical discectomy and fusion with plate (pACDF) and posterior decompression fusion (PDF) instrumentation alone in patients aged 80 years.

METHODS

A single institution retrospective review of electronic medical records was undertaken between September 2005 and December 2021. Comorbidities were assessed using the age-adjusted Charlson comorbidity index (CCI). Logistic regression was used to identify potential risk factors for ACDF complications.

RESULTS

The rate of comorbidities were similarly high between the pACDF (n=13) and PDF (n=15) groups (pACDF: 8.7 ± 2.4 points vs. 8.5 ± 2.3 points; p=0.555). Patients in the PDF group had significantly longer surgical duration (235 ± 58.4 min vs. 182.5 ± 32.1 min; p<0.001) and significantly higher volumes of intraoperative blood loss (661.5 ± 100.1 mL vs. 487.5 ± 92.1 mL; p<0.001). The in-hospital mortality was 7.7% for the pACDF group and 6.7% for the PDF group. On day 90, the mortality rate increased in both groups from baseline (pACDF: 15.4% vs. PDF: 13.3; p>0.05). Motor scores (MS) improved significantly after surgery in both groups (pACDF: preOP MS: 75.3 ± 11.1 vs. postOP MS: 82.4 ± 10.1; p<0.05; PDF: preOP MS: 80.7 ± 16.7 vs. postOP MS: 89.5 ± 12.1; p<0.05). Statistically significant predictors for postoperative complications included longer operative times (odds ratio 1.2, 95% confidence interval 1.1-2.1; p=0.005) and larger volume of blood loss (odds ratio 1.5, 95% confidence interval 1.2-2.2; p=0.003).

CONCLUSIONS

Both pACDF and PDF can be considered safe treatment strategies for octogenarians with a poor baseline profile and subaxial fractures as they lead to patients substantial neurological improvements, and they are accompanied with low morbidity and mortality rates. Operation duration and intraoperative blood loss should be minimized to increase the degree of neurological recovery in octogenarian patients.

Risk Factors for Early Mortality in Older Patients with Traumatic Cervical Spine Injuries-A Multicenter Retrospective Study of 1512 Cases

For older patients with decreased reserve function, traumatic cervical spine injuries frequently lead to early mortality. However, the prognostic factors for early mortality remain unclear. This study included patients aged ≥65 years and hospitalized for treatment of traumatic cervical spine injuries in 78 hospitals between 2010 and 2020. Early mortality was defined as death within 90 days after injury. We evaluated the relationship between early mortality and the following factors: age, sex, body mass index, history of drinking and smoking, injury mechanisms, presence of a cervical spine fracture and dislocation, cervical ossification of the posterior longitudinal ligament, diffuse idiopathic skeletal hyperostosis, American Spinal Injury Association Impairment Scale, concomitant injury, pre-existing comorbidities, steroid administration, and treatment plan. Overall, 1512 patients (mean age, 75.8 ± 6.9 years) were included in the study. The early mortality rate was 4.0%. Multivariate analysis identified older age (OR = 1.1, p < 0.001), male sex (OR = 3.7, p = 0.009), cervical spine fracture (OR = 4.2, p < 0.001), complete motor paralysis (OR = 8.4, p < 0.001), and chronic kidney disease (OR = 5.3, p < 0.001) as risk factors for early mortality. Older age, male sex, cervical spine fracture, complete motor paralysis, and chronic kidney disease are prognostic factors for early mortality in older patients with traumatic cervical spine injuries.

Instantaneous death risk, conditional survival and optimal surgery timing in cervical fracture patients with ankylosing spondylitis: A national multicentre retrospective study

Background

The mortality rate in patients with ankylosing spondylitis (AS) and cervical fracture is relatively high.

Objectives

This study aimed to investigate the instantaneous death risk and conditional survival (CS) in patients with AS and cervical fracture. We also studied the relationship between surgical timing and the incidence of complications.

Methods

This national multicentre retrospective study included 459 patients with AS and cervical fractures between 2003 and 2019. The hazard function was used to determine the risk of instantaneous death. The five-year CS was calculated to show the dynamic changes in prognosis.

Results

The instantaneous death risk was relatively high in the first 6 months and gradually decreased over time in patients with AS and cervical fracture. For patients who did not undergo surgery, the instantaneous risk of death was relatively high in the first 15 months and gradually decreased over time. For patients with American Spinal Injury Association impairment scale (ASIA) A and B, the 5-year CS was 55.3% at baseline, and improved steadily to 88.4% at 2 years. Odds ratios (ORs) for pneumonia, electrolyte disturbance, respiratory insufficiency, and phlebothrombosis decreased as the surgery timing increased.

Conclusion

Deaths occurred mainly in the first 6 months after injury and gradually decreased over time. Our study highlights the need for continued surveillance and care in patients with AS with cervical fractures and provides useful survival estimates for both surgeons and patients. We also observed that early surgery can significantly increase functional recovery, and decrease the incidence of complications and rehospitalisation.

A multicenter study of 1-year mortality and walking capacity after spinal fusion surgery for cervical fracture in elderly patients

Background

The 1-year mortality and functional prognoses of patients who received surgery for cervical trauma in the elderly remains unclear. The aim of this study is to investigate the rates of, and factors associated with mortality and the deterioration in walking capacity occurring 1 year after spinal fusion surgery for cervical fractures in patients 65 years of age or older.

Methods

Three hundred thirteen patients aged 65 years or more with a traumatic cervical fracture who received spinal fusion surgery were enrolled. The patients were divided into a survival group and a mortality group, or a maintained walking capacity group and a deteriorated walking capacity group. We compared patients’ backgrounds, trauma, and surgical parameters between the two groups. To identify factors associated with mortality or a deteriorated walking capacity 1 year postoperatively, a multivariate logistic regression analysis was conducted.

Results

One year postoperatively, the rate of mortality was 8%. A higher Charlson comorbidity index (CCI) score, a more severe the American Spinal Cord Injury Association impairment scale (AIS), and longer surgical time were identified as independent factors associated with an increase in 1-year mortality. The rate of deterioration in walking capacity between pre-trauma and 1 year postoperatively was 33%. A more severe AIS, lower albumin (Alb) and hemoglobin (Hb) values, and a larger number of fused segments were identified as independent factors associated with the increased risk of deteriorated walking capacity 1 year postoperatively.

Conclusions

The 1-year rate of mortality after spinal fusion surgery for cervical fracture in patients 65 years of age or older was 8%, and its associated factors were a higher CCI score, a more severe AIS, and a longer surgical time. The rate of deterioration in walking capacity was 33%, and its associated factors were a more severe AIS, lower Alb, lower Hb values, and a larger number of fused segments.

Baseline predictors of in-hospital mortality after acute traumatic spinal cord injury: data from a level I trauma center

Comorbidity scores are important predictors of in-hospital mortality after traumatic spinal cord injury (tSCI), but the impact of specific pre-existing diseases is unknown. This retrospective cohort study aims at identifying relevant comorbidities and explores the influence of end-of-life decisions. In-hospital mortality of all patients admitted to the study center after acute tSCI from 2011 to 2017 was assessed. A conditional inference tree analysis including baseline data, injury characteristics, and Charlson Comorbidity Index items was used to identify crucial predictors. End-of-life decisions were recorded. Three-hundred-twenty-one patients were consecutively enrolled. The median length of stay was 95.7 days (IQR 56.8-156.0). During inpatient care, 20 patients (6.2%) died. These patients were older (median: 79.0 (IQR 74.7-83.2) vs. 55.5 (IQR 41.4-72.3) years) and had a higher Charlson Comorbidity Index score (median: 4.0 (IQR 1.75-5.50) vs. 0.0 (IQR 0.00-1.00)) compared to survivors. Pre-existing kidney or liver disease were identified as relevant predictors of in-hospital mortality. End-of-life decisions were observed in 14 (70.0%) cases. The identified impairment of kidney and liver, important for drug metabolism and elimination, points to the need of careful decisions on pharmaceutical treatment regimens after tSCI. Appropriate reporting of end-of-life decisions is required for upcoming studies.

A New Scale for Predicting the Risk of In-hospital Mortality in Patients With Traumatic Spinal Cord Injury

Purpose

To analyze the relative factors influencing in-hospital mortality in patients with traumatic spinal cord injury (TSCI), and develop a score scale for predicting the risk of in-hospital mortality.

Method

We reviewed the medical records from 59 spine centers in mainland China from 1 January 2018 to 31 December 2018. The inclusion criteria were (1) confirmed diagnosis of TSCI, (2) hospitalization within 7 days of injury, and (3) affecting neurological level from C1 to L1. The exclusion criteria were (1) readmission, and (2) incomplete data. Included patients were classified into the survival and non-survival groups according to their status at discharge. Univariate and multivariate logistic regressions were performed to identify the factors related to in-hospital mortality in patients with TSCI. A new scale was developed, and the mortality rate in each risk group was calculated.

Results

Of the 3,176 participants, 23 (0.7%) died in the hospital, and most of them died from respiratory diseases (17/23, 73.9%). After univariate and multivariate logistic regression analysis, cervical spinal cord injury [odds ratio (OR) = 0.264, 95% confidence interval (CI): 0.076–0.917, P = 0.036], abdominal visceral injury (OR = 3.778, 95% CI: 1.038–13.755, P = 0.044), the American Spinal Injury Association (ASIA) score on admission (A: reference; B:OR = 0.326, 95% CI: 0.093–1.146, P = 0.081; C:OR = 0.070, 95% CI: 0.016–0.308, P < 0.001; D:OR = 0.069, 95% CI: 0.019–0.246, P < 0.001), and surgery (OR = 0.341, 95% CI: 0.146–0.796, P = 0.013) were significantly associated with in-hospital mortality. Scores for each of the four factors were derived according to mortality rates. The sum of the scores from all four factors was included in the scoring system and represented the risk of in-hospital mortality. The in-hospital mortality risk of the low-risk (0–3 points), moderate-risk (4–5 points), and high-risk groups (6–8 points) was 0.3, 2.7, and 9.7%, respectively (P < 0.001).

Conclusions

Cervical spinal cord injury, abdominal visceral injury, ASIA score on admission, and surgery were significantly associated with in-hospital mortality in patients with TSCI and stable condition. The scale system may be beneficial for clinical decision-making and for communicating relevant information to patients and their families.

Mortality and complications in elderly patients with cervical spine injuries

PURPOSE

To assess the complications and mortality in elderly individuals with cervical spine injuries.

METHODS

This retrospective observational study was conducted in a tertiary care hospital in a rural area in Japan. Data sets from the trauma registry (January 2011 to March 2018) were analyzed. Patients with cervical spine injury were divided into those aged ≥ 65 years (group Y) and > 65 years (group E). We then analyzed age, sex, 30-day mortality, hospital stay, level of cervical spine injury, presence of cervical vertebral fracture, perioperative complications (pneumonia, urinary tract infection, and severe bedsore), neurological deficit (Frankel classification), Abbreviated Injury Scale (AIS) score, and Injury Severity Score (ISS).

RESULTS

We evaluated a total of 398 patients; among them, 177 were included in group Y and 221 in group E. The assessed parameters were as follows: age (group Y/E; 48.7/75.9 years), men (78.0/72.3%), 30-day mortality (8.5/10.0%, p = 0.159), hospital stay (17.2/19.1 days, p = 0.36), level of cervical spine injury (C1 [5.7/4.5%], C2 [12.4/15.8%], C3 [10.2/17.2%], C4 [14.1/16.3%], C5 [26.6/22.2%], C6 [22.0/12.2%], and C7 [11.3/10.9%]), vertebral fracture (56.6/61.9%), central cord syndrome (36.2/33%), operation (18.6/13.1%), pneumonia (6.8/11.8%, p = 0.077), urinary tract infection (4.0/6.3%, p = 0.26), severe bedsore (0/1.8%, p = 0.068), Frankel classification (grade A [5.7/6.3%], grade B [6.8/7.7%], grade C [24.9/28.5%], grade D [17.5/11.8%], and grade E [34.5/33.9%]), mean AIS score in the cervical spine (3.3/3.5, p = 0.04), and mean ISS (23.2/22.2, p = 0.38). C3 injuries tended to be higher in group E.

CONCLUSION

Mortality and morbidity associated with cervical spine injuries did not differ between younger and older patients. Nevertheless, vigilance is required for the detection of C3 injury in elderly individuals.

Clinical characteristics and prognosis of spinal cord injury in individuals over 75 years old

OBJECTIVE

To analyze the incidence and characteristics of traumatic spinal cord injury (SCI) in geriatric population of Galicia (Spain), hospital management and functional prognosis METHODS: Comparative retrospective study. Patients admitted with acute traumatic SCI during the time period between January 2010 and December 2016 were included. Two groups established: The elderly over and under 75 years of age, with the latter acting as a control group.

RESULTS

379 patients were studied (27.2% ≥75 years). The main etiology in the >75 years group were falls: 80.6%. There were 65.7% who presented incomplete spinal cord injuries with mean motor index (MI) of 44.9/100. Upon discharge, 90.8% were dependent. Hospital mortality was 34.9%. Those >75 years suffered from more cervical injuries (74.8 vs. 51.2%, p < 0.001), longer delay in diagnosis (31.1% vs. 9.2%, p < 0.001) and higher hospital mortality (34.9% vs. 3.2%, p < 0.001). Fewer surgical interventions were performed, with a longer delay. Percentages for admission into ICU, mechanical ventilation and performing a tracheostomy proved to be similar. There were no significant differences found in the evolution according to the ASIA scale or the MI.

CONCLUSIONS

1) The frequency of traumatic SCI in the elderly in Galicia is high. 2) Neurological evolution is similar to younger patients but the level of dependence is higher. 3) The level of care provided is similar in both groups, except for the surgical indication. 4) Hospital mortality is high.

In-Hospital Mortality for the Elderly with Acute Traumatic Spinal Cord Injury

As the incidence of traumatic spinal cord injury (tSCI) in the elderly rises, clinicians are increasingly faced with difficult discussions regarding aggressiveness of management, likelihood of recovery, and survival. Our objective was to outline risk factors associated with in-hospital mortality in elderly surgical and non-surgical patients following tSCI and to determine those unlikely to have a favorable outcome. Data from elderly patients (≥ 65 years of age) in the Canadian Rick Hansen SCI Registry from 2004 to 2017 were analyzed using descriptive analysis. Survival and mortality groups in each of the surgical and non-surgical group were compared to explore factors associated with in-hospital mortality and their impact, using logistical regression. Of 1340 elderly patients, 1018 had surgical data with 826 having had surgery. In the surgical group, the median time to death post-injury was 30 days with 75% dying within 50 days compared with 7 days and 20 days, respectively, in the non-surgical group. Significant predictors for in-hospital mortality following surgery are age, comorbidities, neurological injury severity (American Spinal Injury Association [ASIA] Impairment Scale [AIS]), and ventilation status. The odds of dying 50 days post-surgery are six times higher for patients ≥77 years of age versus those 65–76 years of age, five times higher for those with AIS A versus those with AIS B/C/D, and seven times higher for those who are ventilator dependent. An expected probability of dying within 50 days post-surgery was determined using these results. In-hospital mortality in the elderly after tSCI is high. The trend with age and time to death and the significant predictors of mortality identified in this study can be used to inform clinical decision making and discussions with patients and their families.

1-Year Mortality and Surgery Incidence in Older US Adults with Cervical Spine Fracture

BACKGROUND

Traumatic cervical spinal cord injuries (SCIs) can be lethal and are especially dangerous for older adults. Falls from standing and risk factors for a cervical fracture and spinal cord injury increase with age. This study estimates the 1-year mortality for patients with a cervical fracture and resultant SCI and compares the mortality rate with that from an isolated cervical fracture.

METHODS

We performed a retrospective cohort study of U.S. Medicare patients older than 65 years of age. International Classification of Diseases (ICD)-9 codes were used to identify patients with a cervical fracture without SCI and patients with a cervical fracture with SCI between 2007 and 2014. Our primary outcome was 1-year mortality cumulative incidence rate; our secondary outcome was the cumulative incidence rate of surgical intervention. Propensity weighted analysis was performed to balance covariates between the groups.

RESULTS

The SCI cohort had a 1-year mortality of 36.5%, compared with 31.1% in patients with an isolated cervical fracture (risk difference 5.4% (2.9%-7.9%)). Patients with an SCI were also more likely to undergo surgical intervention compared with those without a SCI (23.1% and 10.3%, respectively; risk difference 12.8% (10.8%-14.9%)).

CONCLUSIONS

Using well-adjusted population-level data in older adults, this study estimates the 1-year mortality after SCI in older adults to be 36.5%. The mortality after a cervical fracture with SCI was 5 percentage points higher than in patients without SCI, and this difference is smaller than one might expect, likely representing the frailty of this population and unmeasured covariates.

Value of aggressive surgical and intensive care unit in elderly patients with traumatic spinal cord injury

OBJECTIVEThe elderly are a growing subpopulation within traumatic spinal cord injury (SCI) patients. Studies have reported high morbidity and mortality rates in elderly patients who undergo surgery for SCI. In this study, the authors compare the perioperative outcomes of surgically managed elderly SCI patients with those of a younger cohort and those reported in the literature.METHODSData on a consecutive series of adult traumatic SCI patients surgically managed at a single institution in the period from 2007 to 2017 were retrospectively reviewed. The cohort was divided into two groups based on age: younger than 70 years and 70 years or older. Assessed outcomes included complications, in-hospital mortality, intensive care unit (ICU) stay, hospital length of stay (LOS), disposition, and neurological status.RESULTSA total of 106 patients were included in the study: 83 young and 23 elderly. The two groups were similar in terms of imaging features (cord hemorrhage and fracture), operative technique, and American Spinal Injury Association Impairment Scale (AIS) grade. The elderly had a significantly higher proportion of cervical SCIs (95.7% vs 71.1%, p = 0.047). There were no significant differences between the young and the elderly in terms of the ICU stay (13.1 vs 13.3 days, respectively, p = 0.948) and hospital LOS (23.3 vs 21.7 days, p = 0.793). Elderly patients experienced significantly higher complication (73.9% vs 43.4%, p = 0.010) and mortality (13.0% vs 1.2%, p = 0.008) rates; in other words, the elderly patients had 1.7 times and 10.8 times the rate of complications and mortality, respectively, than the younger patients. No elderly patients were discharged home (0.0% vs 18.1%, p = 0.029). Discharge AIS grade and AIS grade change were similar between the groups.CONCLUSIONSElderly patients had higher complication and mortality rates than those in younger patients and were less likely to be discharged home. However, it does seem that mortality rates have improved compared to those in prior historical reports.

Subaxial Cervical Spine Injury in the Elderly and Treatment-Related Mortality - Anterior or Posterior Approach

BACKGROUND

Subaxial cervical spine injury especially in the elderly can be associated to severe complications and disability. Until today there is no consensus concerning the best operative treatment. A potential superiority of anterior or posterior fixation is the subject of controversial discussions.

OBJECTIVES

The aim of this study was to compare the outcome of anterior and posterior fixation after subaxial cervical spine trauma in the elderly focussing on the postoperative mortality.

MATERIAL AND METHODS

A retrospective cohort analysis was performed to analyse the data of 43 patients. Especially mortality data were collected.

RESULTS

A total of 43 patients was identified. Anterior fixation was performed in 21 patients, posterior fixation was performed in 22 patients. There were no significant differences between these groups. Although statistical significance was not reached, a slightly higher mortality was found among patients undergoing anterior fixation (52,4 vs. 31,8%). Furthermore the male sex, a higher age, translation injuries, long duration of operation and hospitalisation as well as postoperative complications were slightly associated to a higher mortality.

CONCLUSIONS

Subaxial cervical spine trauma is associated to a high mortality in the elderly. Although neither anterior nor posterior fixation could show a significant superiority, every surgical decision making should be performed individually for each patient balancing the advantages and disadvantages of each method.

Cervical Spine Injury in Burned Trauma Patients: Incidence, Predictors, and Outcomes

Cervical spine injuries (CIs) carry significant morbidity and mortality; hence, cervical spine immobilization is used liberally in trauma patients, including burns. The incidence, predictors, and outcomes of CI in burn patients are unknown. A retrospective cohort from the National Trauma Data Bank between 2007 and 2012 included all burned patients with and without CI. Predictors of CI were identified by logistic regression. Outcomes with and without CI were compared with Wilcoxon rank sum test. A total of 94,964 patients were identified with burn injuries. The incidence of CI was 0.79% (n = 745). Mechanism of injury, age, and injury severity score (ISS) were significant predictors of CI. Odds of CI were 109.4 (95% CI: 61.2-195.3, P < .0001) for motor vehicle injury, 87.8 (95% CI: 47.0-164.0, P < .0001) for falls, 1.2 (95% CI: 0.6-2.3, P = .66) for fire/flame, and 2.4 (95% CI: 1.0-5.5, P < .0001) for explosion compared with reference of hot object/substance. For every year increase in age, there were 1.02 higher odds of CI (95% CI: 1.01-1.02, P < .0001). For each point increase in ISS, there were 1.05 higher odds of CI (95% CI: 1.04-1.05, P < .0001). Patients with CI had higher mortality (10.3% vs 2.9%, P < .0001), longer total length of stay (12.0 vs 2.0 days, P < .0001), intensive care unit length of stay (4.0 vs 0.0 days, P < .001), and ventilator days (1.0 vs 0.0 days, P < .0001). The incidence of CI in burn patients is low, especially when due to fire, flame, or scalds; however, CI is associated with higher mortality and worse outcomes.

Factors Impacting Mortality in Geriatric Patients with Acute Spine Fractures: A 12-Year Study of 613 Patients in Singapore

Study Design

Retrospective database analysis.

Purpose

To identify risk factors that predict mortality following acute spine fractures in geriatric patients of Singapore.

Overview of Literature

Acute geriatric spinal fractures contribute significantly to local healthcare costs and hospital admissions. However, geriatric mortality following acute spine fractures is scarcely assessed in the Asian population.

Methods

Electronic records of 3,010 patients who presented to our hospital’s emergency department and who were subsequently admitted during 2004–2015 with alleged history of traumatic spine fractures were retrospectively reviewed, and 613 patients (mean age, 85.7±4.5 years; range, 80–101 years; men, 108; women, 505) were shortlisted. Mortality rates were reviewed up to 1 year after admission and multivariate analyses were performed to identify independent risk factors correlating with mortality.

Results

Women were more susceptible to spine fractures (82.4%), with falls (77.8%) being the most common mechanism of injury. Mortality rates were 6.0%, 8.2%, and 10.4% at 3, 6, and 12 months, respectively. The most common causes of death at all 3 time points were pneumonia and ischemic heart disease. Based on the multivariate analysis at 1-year follow-up, elderly women had a lower mortality rate compared to men (p<0.001); mortality rates increased by 6.3% (p=0.024) for every 1-year increase in the patient’s age; and patients with an American Spinal Injury Association (ASIA) score of A–C had a much higher mortality rate compared to those with an ASIA score of D–E (p<0.001).

Conclusions

An older age at presentation, male sex, and an ASIA score of A–C were identified as independent factors predicting increased mortality among geriatric patients who sustained acute spine fractures. The study findings highlight at-risk groups for acute spine fractures, thereby providing an opportunity to develop strategies to increase the life expectancy of these patients.

Survival in 222 Patients With Severe CSCI: An 8-Year Epidemiologic Survey in Western China

OBJECTIVE

To assess the survival and the predictors of mortality in patients with severe cervical spinal cord injuries (CSCI).

DESIGN

Retrospective study.

PARTICIPANTS

From January 1, 2010, to May 31, 2018, patients who suffered from severe CSCIs in Western China were enrolled in this study (N=222).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Survival rates and mortality risk factors. Measures were calculated by the product-limit method (Kaplan-Meier) and the Cox model.

RESULTS

The overall 1-year, 3-year, 5-year, and 8-year postoperative mortalities were 24.4%, 30.6%, 33.3%, 36.2%, and 39.0%, respectively. Most deaths occurred within 36 months after the injury. According to the Cox proportional hazards model, the significant predictors of survival were as follows: (1) age; (2) neurologic level; (3) treatment options (surgical or conservative); (4) ventilator support (P<.05). The 8-year mortality for older patients (>50y) was 50.2%, which was significantly higher than that for younger patients (32.4%, <50y). The risk of death was 2.053 times higher in higher levels of injury (C1-C4) than in lower levels of injury (C5-C8) (P<.05). Compared with conservative treatment, patients who received surgical treatment (either anterior or posterior decompression) had a lower risk of death (P<.05). No significant difference was detected in the risk of death between early surgery (<3d) and mid-term surgery (3-7d) (P>.05). However, patients who received late-term surgery (>7d) had a higher mortality risk (P<.05). The overall 8-year mortality risk of patients who needed ventilator support was much higher than those who did not need ventilator support (P<.05).

CONCLUSIONS

Age, neurologic level, ventilator dependence, treatment options, and timing to surgery were main risk factors for mortality in patients with severe CSCIs. Better understanding of the predictors for survival could possibly contribute to the improvement of survival rates.

Brief teaching sessions change behaviour in A&E

BACKGROUND

The Accident and Emergency Department (A&E) is a busy environment that requires time- and resource-efficient teaching. Managing cervical spine (c-spine) trauma is often an unfamiliar skill for new doctors starting work in A&E. This study investigated the efficacy of brief teaching interventions in changing clinician behaviour within A&E. The Accident and Emergency Department is a busy environment that requires time- and resource-efficient teaching METHODS: Data for 482 patients receiving c-spine computed tomography (CT) imaging in two Gloucestershire A&Es before and after multimodal departmental teaching were compared. Time taken to CT, indication for CT scan and presence of bony injury were manually recorded from patient management software.

RESULTS

Following the provision of teaching, the proportion of CT scans performed within 1 hour did not significantly change, from 31% before teaching to 37.6% after teaching (p = 0.133); however, the mean number of c-spine CT scans performed per week rose from 14.50 to 23.25 (p = 0.0001), and the mean number of CT scans performed per week within 1 hour rose from 4.50 to 8.75 (p ≤ 0.001). There was no reduction in the quality of these scans, with the proportion detecting bony injury remaining constant, and there was no increase in the proportion of scans not indicated by National Institute for Health and Care Excellence guidelines.

CONCLUSIONS

This study demonstrates that brief, low-resource teaching can be associated with a positive change in clinician behaviour. This intervention was straightforward to implement and is likely to be transferable to other guideline-driven investigations. Limitations include the patient cohort being proportionately older than that found in major trauma centres, and a lack of data on patients in whom CT scans were indicated but not performed.

Preinjury Patient Characteristics and Postinjury Neurological Status Are Associated With Mortality Following Spinal Cord Injury

STUDY DESIGN

Retrospective cohort study.

OBJECTIVES

This study investigates the association between spinal cord injuries (SCI) and post-injury mortality.

SUMMARY OF BACKGROUND DATA

SCIs) are severe conditions treated in the acute trauma setting. Owing to neurological deficits, unstable spinal columns, and associated injuries, these patients often have complex inpatient hospitalizations with significant morbidity and mortality. It is assumed that a high rate of postinjury mortality would follow such severe injuries; however, the effect of SCI and its treatment on predictors of longevity remain largely unknown.

METHODS

Patients seen at a regional referral center for SCI were reviewed from a prospectively maintained database. Four hundred and twenty-six patients with SCI and varying degrees of injury between 2004 and 2009 were collected. Injury characteristics, including injury severity score, level of SCI, and type of SCI were retrieved. To determine independent predictors of 5-year mortality, a logistic regression using patient and injury characteristics at the time of presentation was performed.

RESULTS

Average age was 47.4 years (range: 14-95), and 74.5% (318/426) were male. Half of the cohort sustained low-energy mechanisms of injury (220/426; 52.4%). The 30-day, 90-day, 1-year, 2-year, and 5-year mortality rates in the SCI cohort were 6.6% (28/426), 9.2% (39/426), 12.0% (51/426), 15.0% (64/426), and 17.8%, respectively (76/426). Logistic regression demonstrated that increasing age (B = 1.06, P < 0.001), increasing ICU length-of-stay (B = 1.06; P = 0.002), decreased motor score at presentation (B = 0.98; P = 0.004), and lack of surgical intervention (B = 0.38; P < 0.001) were independent predictors of mortality at 5 years.

CONCLUSION

There is substantial mortality associated with SCI. A significant proportion of the mortalities occurred acutely after injury. Mortality was associated with neurological deficit and severity of injury, as well as with preinjury patient characteristics. To combat this high rate of death, efforts are needed to address the concomitant disease processes associated with neurological deficits.

Age and Other Risk Factors Influencing Long-Term Mortality in Patients With Traumatic Cervical Spine Fracture

Objective

To identify clinical or demographic variables that influence long-term mortality, as well as in-hospital mortality, with a particular focus on the effects of age.

Summary and Background Data

Cervical spine fractures with or without spinal cord injury (SCI) disproportionately impact the elderly who constitute an increasing percentage of the US population.

Methods

We analyzed data collected for 10 years at a state-designated level I trauma center to identify variables that influenced in-hospital and long-term mortality among elderly patients with traumatic cervical spine fracture with or without SCI. Acute in-hospital mortality was determined from hospital records and long-term mortality within the study period (2003-2013) was determined from the National Death Index. Univariate and multivariate regression analyses were used to identify factors influencing survival.

Results

Data from patients (N = 632) with cervical spine fractures were analyzed, the majority (66%) of whom were geriatric (older than age 64). Most patients (62%) had a mild/moderate injury severity score (ISS; median, interquartile range: 6, 5). Patients with SCI had significantly longer lengths of stay (14.1 days), days on a ventilator (3.5 days), and higher ISS (14.9) than patients without SCI (P < .0001 for all). Falls were the leading mechanism of injury for patients older than age 64. Univariate analysis identified that long-term survival decreased significantly for all patients older than age 65 (hazard ratio [HR]: 1.07; P < .0001). Multivariate analysis demonstrated age (HR: 1.08; P < .0001), gender (HR: 1.60; P < .0007), and SCI status (HR: 1.45, P < .02) significantly influenced survival during the study period.

Conclusion

This study identified age, gender, and SCI status as significant variables for this study population influencing long-term survival among patients with cervical spine fractures. Our results support the growing notion that cervical spine injuries in geriatric patients with trauma may warrant additional research.

Risk factors and the surgery affection of respiratory complication and its mortality after acute traumatic cervical spinal cord injury

The aim of this study is to estimate the risk factors of both respiratory complication (RC) and mortality after acute traumatic cervical spinal cord injury (TCSCI). Between July 2005 and July 2015, in 181 patients (142 males and 39 females; mean age 41.0 years) with acute TCSCI, we compared the difference and odds ratio in RC group (n = 73) with that of non-RC group (n = 108), and also death group (n = 15) and survival group (n = 166). We collected injury-related information after half a year of injury, which is as follows: the causes of injury, time of surgery, ICU (intensive care unit) days, ventilator days, ASIA (American Spinal Injury Association) classification, neurological injury, CIPS (Clinical Pulmonary Infection Score), and BMI (body mass index). Besides these, we gathered the general information such as age, gender, smoking history, and use of steroids. The study compared perioperative parameters; surgery-related and instrumentation- and graft-related complication rates; clinical parameters; patient satisfaction; and radiologic parameters. Variations like gender (odds ratio [OR] = 1.269, 95% confidence interval [CI] [0.609-2.646]), smoking history (OR = 2.902, 95% CI [1.564-5.385]), AIS grade (grade A) (OR = 6.439, 95% CI [3.334-12.434]), neurological level (C1-C4) (OR = 2.714, 95% CI [1.458-5.066]), and steroid use (OR = 2.983, 95% CI [1.276-6.969]) have a facilitated effect on RC. When we estimated surgery-related affection, only the time of surgery and anterior approach compared with posterior has significant difference in RC (P < .05). Between death and survival group, the aspect of age, non-surgical, CPIS, AIS grade, and BMI have statistically significant difference. Survival analysis reveals significant difference in aforementioned groups. In patients suffering from acute TCSCI, those who are old, have long smoking history, complete spinal cord injury, C1-C4, high CPIS, and fat have high incidence of RC and mortality.

Mini-open anterior approach for cervicothoracic junction fracture: technical note

Elderly patients with diffuse idiopathic skeletal hyperostosis are at high risk for falls, and 3-column unstable fractures present multiple challenges. Unstable fractures across the cervicothoracic junction are associated with significant morbidity and require fixation, which is commonly performed through a posterior open or percutaneous approach. The authors describe a novel, navigated, mini-open anterior approach using intraoperative cone-beam CT scanning to place lag screws followed by an anterior plate in a 97-year-old patient. This approach is less invasive and faster than an open posterior approach and can be considered as an option for management of cervicothoracic junction fractures in elderly patients with high perioperative risk profile who cannot tolerate being placed prone during surgery.

Failure of Mean Arterial Pressure Goals to Improve Outcomes Following Penetrating Spinal Cord Injury

BACKGROUND:

Increased spinal cord perfusion and blood pressure goals have been recommended for spinal cord injury (SCI). Penetrating SCI is associated with poor prognosis, but there is a paucity of literature examining the role of vasopressor administration for the maintenance of mean arterial pressure (MAP) goals in this patient population.

OBJECTIVE:

To elucidate this topic and to determine the efficacy of vasopressor administration in penetrating SCI by examining a case series of consecutive penetrating SCIs.

METHODS:

We reviewed consecutive patients with complete penetrating SCI who met inclusion and exclusion criteria, including the administration of vasopressors to maintain MAP goals. We identified 14 patients with complete penetrating SCIs with an admission American Spinal Injury Association grade of A from 2005 to 2011. The neurological recovery, complications, interventions, and vasopressor administration strategies were reviewed and compared with those of a cohort with complete blunt SCI.

RESULTS:

In our patient population, only 1 patient with penetrating SCI (7.1%) experienced neurological recovery, as determined by improvement in the American Spinal Injury Association grade, despite the administration of vasopressors for supraphysiological MAP goals for an average of 101.07 ± 34.96 hours. Furthermore, 71.43% of patients with penetrating SCI treated with vasopressors experienced associated cardiogenic complications.

CONCLUSION:

Given the decreased likelihood of neurological improvement in penetrating injuries, it may be important to re-examine intervention strategies in this population. Specifically, the use of vasopressors, in particular dopamine, with their associated complications is more likely to cause complications than to result in neurological improvement. Our experience shows that patients with acute penetrating SCI are unlikely to recover, despite aggressive cardiopulmonary management.
