A scoping review of models of care for the management of older trauma patients

INTRODUCTION

The number of older people hospitalised with major trauma is rapidly increasing. New models of care have emerged, such as co-management, and trauma centres dedicated to delivering geriatric trauma care. The aim of this scoping review was to explore in-hospital models of care for older adults who experience physical trauma.

PATIENTS AND METHODS

The search was conducted in accordance with the PRISMA- SC (preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews) reporting guidelines. The National Heart Lung, and Blood Institute (NIH) study quality assessment tool was used to evaluate risk of bias in before and after non-randomised experimental studies.

RESULTS

Of 2127 records returned from the database search, 43 papers were included. We identified five types of care models investigated in the reviewed studies: centralised trauma management, consultation services, co-management, patient care protocols, and alert and triage systems. The majority of patients were admitted under a specialised trauma service, intervention teams were for the most part multidisciplinary, and follow-up of patients post-discharge was seldom reported. Consultation services more often had advanced care and discharge planning as treatment objectives. In contrast, patient care protocol and alert systems commonly had management of anticoagulation as a treatment objective. Overall, the impact of the five models of care on patient outcomes was mixed.

DISCUSSION

Given the variability in patient characteristics and capabilities of health services, models of care need to be matched to the local profile of older trauma patients. However, some standards should be incorporated into a care model, including identifying goals of care, medication review and follow up post-discharge.

A qualitative descriptive study exploring clinicians' perspectives of the management of older trauma care in rural Australia

BACKGROUND

For older trauma patients who sustain trauma in rural areas, the risk of adverse outcomes associated with advancing age, is compounded by the challenges encountered in rural healthcare such as geographic isolation, lack of resources, and accessibility. Little is known of the experience and challenges faced by rural clinicians who manage trauma in older adults. An understanding of stakeholders' views is paramount to the effective development and implementation of a trauma system inclusive of rural communities. The aim of this descriptive qualitative study was to explore the perspectives of clinicians who provide care to older trauma patients in rural settings.

METHOD

We conducted semi-structured interviews of health professionals (medical doctors, nurses, paramedics, and allied health professionals) who provide care to older trauma patients in rural Queensland, Australia. A thematic analysis consisting of both inductive and deductive coding approaches, was used to identify and develop themes from interviews.

RESULTS

Fifteen participants took part in the interviews. Three key themes were identified: enablers of trauma care, barriers, and changes to improve trauma care of older people. The resilience of rural residents, and breadth of experience of rural clinicians were strengths identified by participants. The perceived systemic lack of resources, both material and in the workforce, and fragmentation of the health system across the state were barriers to the provision of trauma care to older rural patients. Some changes proposed by participants included tailored education programs that would be taught in rural centres, a dedicated case coordinator for older trauma patients from rural areas, and a centralised system designed to streamline the management of older trauma patients coming from rural regions.

CONCLUSIONS

Rural clinicians are important stakeholders who should be included in discussions on adapting trauma guidelines to the rural setting. In this study, participants formulated pertinent and concrete recommendations that should be weighed against the current evidence, and tested in rural centres.

Potentially Inappropriate Medications are Associated With Geriatric Trauma Recidivism

INTRODUCTION

The American Geriatric Society has identified polypharmacy and categories of potentially inappropriate medication (PIM) that should be avoided in the elderly. These medications can potentially cause an increased risk of falls and traumatic events.

MATERIALS AND METHODS

We conducted a retrospective study on elderly patients with traumatic injuries at a Level 1 trauma center. We compared patients having only one traumatic event and those with one or more traumatic events with the presence of prescriptions for PIMs.

RESULTS

Identified high risk categories of anticoagulant and antiplatelet agents (odds ratio [OR] 1.18, 95% confidence interval [CI] 1.08-1.28), psychiatric and neurologic agents (OR 1.32, 95% CI 1.22-1.43), as well as medication with anticholinergic properties (OR 1.14, 95% CI 1.03-1.27) were associated with an increased risk of recurrent trauma.

CONCLUSIONS

We can quantify the risk of recurrent trauma with certain categories of PIM. Medication reconciliation and shared decision-making regarding the continued use of these medications may positively impact trauma recidivism.

The DEPARTS Score: A Novel Tool for Predicting Discharge Disposition in Geriatric Trauma Patients

BACKGROUND

Geriatric trauma patients (GTPs) represent a high-risk population for needing post-acute care, such as skilled nursing facilities (SNFs) and long-term acute care hospitals (LTACs), due to a combination of traumatic injuries and baseline functional health. As there is currently no well-established tool for predicting these needs, we aimed to create a scoring tool that predicts disposition to SNFs/LTACs in GTPs.

METHODS

The adult 2017 Trauma Quality Improvement Program database was divided at random into two equal sized sets (derivation and validation sets) of GTPs >65 years old. First, multiple logistic regression models were created to determine risk factors for discharge to a SNF/LTAC in admitted GTPs. Second, the weighted average and relative impact of each independent predictor was used to derive a DEPARTS (Discharge of Elderly Patients After Recent Trauma to SNF/LTAC) score. We then validated the score using the area under the receiver-operating curve (AROC).

RESULTS

Of 66 479 patients in the derivation set, 36 944 (55.6%) were discharged to a SNF/LTAC. Number of comorbidities, fall mechanism, spinal cord injury, long bone fracture, and major surgery were each independent predictors for discharge to SNF/LTAC, and a DEPARTS score was derived with scores ranging from 0 to 19. The AROC for this was .74. In the validation set, 66 477 patients also had a SNF/LTAC discharge rate of 55.7%, and the AROC was .74.

DISCUSSION

The DEPARTS score is a good predictor of SNF/LTAC discharge for GTPs. Future prospective studies are warranted to validate its accuracy and clinical utility in preventing delays in discharge.

Prospective validation and application of the Trauma-Specific Frailty Index: Results of an American Association for the Surgery of Trauma multi-institutional observational trial

BACKGROUND

The frailty index is a known predictor of adverse outcomes in geriatric patients. Trauma-Specific Frailty Index (TSFI) was created and validated at a single center to accurately identify frailty and reliably predict worse outcomes among geriatric trauma patients. This study aims to prospectively validate the TSFI in a multi-institutional cohort of geriatric trauma patients.

METHODS

This is a prospective, observational, multi-institutional trial across 17 American College of Surgeons Levels I, II, and III trauma centers. All geriatric trauma patients (65 years and older) presenting during a 3-year period were included. Frailty status was measured within 24 hours of admission using the TSFI (15 variables), and patients were stratified into nonfrail (TSFI, ≤0.12), prefrail (TSFI, 0.13-0.25), and frail (TSFI, >0.25) groups. Outcome measures included index admission mortality, discharge to rehabilitation centers or skilled nursing facilities (rehab/SNFs), and 3-month postdischarge readmissions, fall recurrences, complications, and mortality among survivors of index admission.

RESULTS

A total of 1,321 geriatric trauma patients were identified and enrolled for validation of TSFI (nonfrail, 435 [33%]; prefrail, 392 [30%]; frail, 494 [37%]). The mean ± SD age was 77 ± 8 years; the median (interquartile range) Injury Severity Score was 9 (5-13). Overall, 179 patients (14%) had a major complication, 554 (42%) were discharged to rehab/SNFs, and 63 (5%) died during the index admission. Compared with nonfrail patients, frail patients had significantly higher odds of mortality (adjusted odds ratio [aOR], 1.93; p = 0.018), major complications (aOR, 3.55; p < 0.001), and discharge to rehab/SNFs (aOR, 1.98; p < 0.001). In addition, frailty was significantly associated with higher adjusted odds of mortality, major complications, readmissions, and fall recurrence at 3 months postdischarge ( p < 0.05).

CONCLUSION

External applicability of the TSFI (15 variables) was evident at a multicenter cohort of 17 American College of Surgeons trauma centers in geriatric trauma patients. The TSFI emerged as an independent predictor of worse outcomes, both in the short-term and 3-month postdischarge.

Developing a National Trauma Research Action Plan: Results from the geriatric research gap Delphi survey

BACKGROUND

Treating older trauma patients requires a focus on the confluence of age-related physiological changes and the impact of the injury itself. Therefore, the primary way to improve the care of geriatric trauma patients is through the development of universal, systematic multidisciplinary research. To achieve this, the Coalition for National Trauma Research has developed the National Trauma Research Action Plan that has generated a comprehensive research agenda spanning the continuum of geriatric trauma care from prehospital to rehabilitation.

METHODS

Experts in geriatric trauma care and research were recruited to identify current gaps in clinical geriatric research, generate research questions, and establish the priority of these questions using a consensus-driven Delphi survey approach. Participants were identified using established Delphi recruitment guidelines ensuring heterogeneity and generalizability. On subsequent surveys, participants were asked to rank the priority of each research question on a nine-point Likert scale, categorized to represent low-, medium-, and high-priority items. The consensus was defined as more than 60% of panelists agreeing on the priority category.

RESULTS

A total of 24 subject matter experts generated questions in 109 key topic areas. After editing for duplication, 514 questions were included in the priority ranking. By round 3, 362 questions (70%) reached 60% consensus. Of these, 161 (44%) were high, 198 (55%) medium, and 3 (1%) low priority.

CONCLUSION

Among the questions prioritized as high priority, questions related to three types of injuries (i.e., rib fracture, traumatic brain injury, and lower extremity injury) occurred with the greatest frequency. Among the 25 highest priority questions, the key topics with the highest frequency were pain management, frailty, and anticoagulation-related interventions. The most common types of research proposed were interventional clinical trials and comparative effectiveness studies, outcome research, and health care systems research.

Association of Trauma Center Designation With Postdischarge Survival Among Older Adults With Injuries

Importance

Trauma centers improve outcomes for young patients with serious injuries. However, most injury-related hospital admissions and deaths occur in older adults, and it is not clear whether trauma center care provides the same benefit in this population.

Objective

To examine whether 30- and 365-day mortality of injured older adults is associated with the treating hospital's trauma center level.

Design, Setting, and Participants

This prospective, population-based cohort study used Medicare claims data from January 1, 2013, to December 31, 2016, for all fee-for-service Medicare beneficiaries 66 years or older with inpatient admission for traumatic injury in 2014 to 2015. Data analysis was performed from January 1 to June 31, 2021. Preinjury health was measured using 2013 claims, and outcomes were measured through 2016. The population was stratified by anatomical injury pattern. Propensity scores for level I trauma center treatment were estimated using the Abbreviated Injury Scale, age, and residential proximity to trauma center and then used to match beneficiaries from each trauma level (I, II, III, and IV/non-trauma centers) by injury type.

Exposure

Admitting hospital's trauma center level.

Main Outcomes and Measures

Case fatality rates (CFRs) at 30 and 365 days after injury, estimated in the matched sample using multivariable, hierarchical logistic regression models.

Results

A total of 433 169 Medicare beneficiaries (mean [SD] age, 82.9 [8.3] years; 68.4% female; 91.5% White) were included in the analysis. A total of 206 275 (47.6%) were admitted to non-trauma centers and 161 492 (37.3%) to level I or II trauma centers. Patients with isolated extremity fracture had the fewest deaths (365-day CFR ranged from 16.1% [95% CI, 11.2%-22.4%] to 17.4% [95% CI, 11.8%-24.6%] by trauma center status). Patients with both hip fracture and traumatic brain injury had the most deaths (365-day CFRs ranged from 33.4% [95% CI, 25.8%-42.1%] to 35.8% [95% CI, 28.9%-43.5%]).

Conclusions and Relevance

These findings suggest that older adults do not benefit from existing trauma center care, which is designed with younger patients in mind. There is a critical need to improve trauma care practices to address common injury mechanisms and types of injury in older adults.

Challenges in the PREHOSPITAL emergency management of geriatric trauma patients - a scoping review

BACKGROUND

Despite a widely acknowledged increase in older people presenting with traumatic injury in western populations there remains a lack of research into the optimal prehospital management of this vulnerable patient group. Research into this cohort faces many uniqu1e challenges, such as inconsistent definitions, variable physiology, non-linear presentation and multi-morbidity. This scoping review sought to summarise the main challenges in providing prehospital care to older trauma patients to improve the care for this vulnerable group.

METHODS AND FINDINGS

A scoping review was performed searching Google Scholar, PubMed and Medline from 2000 until 2020 for literature in English addressing the management of older trauma patients in both the prehospital arena and Emergency Department. A thematic analysis and narrative synthesis was conducted on the included 131 studies. Age-threshold was confirmed by a descriptive analysis from all included studies. The majority of the studies assessed triage and found that recognition and undertriage presented a significant challenge, with adverse effects on mortality. We identified six key challenges in the prehospital field that were summarised in this review.

CONCLUSIONS

Trauma in older people is common and challenges prehospital care providers in numerous ways that are difficult to address. Undertriage and the potential for age bias remain prevalent. In this Scoping Review, we identified and discussed six major challenges that are unique to the prehospital environment. More high-quality evidence is needed to investigate this issue further.

Impact of a geriatric consultation service on outcomes in older trauma patients: a before-after study

PURPOSE

Early geriatric involvement is recommended for older trauma patients. We wished to determine the impact of geriatric consultation on mortality, hospital length of stay and discharge disposition in older patients who were admitted to our Level 1 trauma unit.

METHODS

We completed a health records review of trauma unit patients, age ≥ 75 years old with Injury Severity Score (ISS) ≥ 12, before (11/2015-10/2017) and after (11/2017-10/2019) implementation of a geriatric trauma consultation initiative. Primary outcomes were mortality, hospital length of stay and discharge destination. Secondary objectives were adherence to the geriatric trauma consult process and identification of geriatric-specific issues. A multivariable analysis controlling for age, gender, multi-morbidity and ISS was undertaken.

RESULTS

157 patients pre-implementation and 172 post-implementation with mean age 83.8 years and 53.8% females were included. Geriatric consultation had no impact on in-hospital mortality [OR 0.70 (95% CI 0.31-1.58)] or length of stay [ß 0.68 (95%CI - 1.35-2.72)]. Patients who received a geriatric consultation were more likely to be discharged home (OR 2.01 (95% CI 1.24-3.24). The adherence to consultation process was 99.4%. Mobility, pain and cognitive impairment were the most common geriatric concerns, identified in 76.6, 61.1 and 50.0% of older trauma patients, respectively.

CONCLUSION

Older trauma patients that receive geriatric trauma consultation are more likely to be discharged home. Collaboration between trauma and geriatric specialists is beneficial and may lead to meaningful improvements in outcomes for older trauma patients.

Frailty Interdisciplinary Pathway: Compliance and Sustainability in a Level I Trauma Center

BACKGROUND

Frailty is a state of physiological vulnerability that predisposes many older adult trauma patients to poor health outcomes. Specialized care pathways for frail trauma patients have been shown to improve outcomes, but the compliance and sustainability of these pathways have not been reported (Bryant et al., 2019; Engelhardt et al., 2018).

METHODS

We retrospectively measured compliance and sustainability during the first 2 years of a frailty pathway for patients 65 years or older at an urban Level I trauma center. Compliance to 19 pathway elements was collected for 279 pathway patients between October 1, 2016, and September 30, 2018. Compliance was analyzed and reported as a percentage of the total possible times each element could have been completed per pathway guidelines. Benchmark compliance was 75% or more.

RESULTS

Retrospective 2-year mean overall compliance to all pathway elements was 68.2% and improved from Year 1 (65.0%) to Year 2 (71.4%). Seven elements achieved a mean 75% or more compliance over the 2-year period: frailty screening on admission (92.8%), consultation requests for physical therapy (97.9%), geriatrics (96.2%), and nutrition (92.3%), consultant care within 72 hr of admission (78.0%), delirium screening 3 times daily (76.3%), and daily senna administration (76.0%). Compliance to 10 elements significantly improved from Year 1 to Year 2 and significantly worsened in 2 elements.

CONCLUSION

Many standardized geriatric care processes for frail older adult trauma patients can be successfully integrated into routine daily inpatient practice and sustained over time. Multicenter studies are needed to demonstrate how to improve compliance and to understand better which pathway elements are most effective.

Biodebridement in the Surgical Intensive Care Unit: Unique Therapy for Unique Patients

Acute care surgery has evolved to encompass the advanced management of complex nonhealing wounds. Biodebridement has the potential to improve the care of chronic wounds for acute care surgery patients, particularly for patients in the surgical intensive care unit (SICU) with hospital-acquired pressure injuries. A case report of biodebridement using larval maggot therapy in the SICU is presented to illustrate real-world application and progression in wound healing. A review of current research involving biodebridement was conducted. A septuagenarian gentleman sustained a fall resulting in cervical spine fractures with neurological deficits. The patient had a prolonged hospital course in the SICU, complicated by myocardial infarction, respiratory failure requiring tracheostomy, and development of a Stage IV sacral pressure ulcer. The wound base was sharply debrided several times and became refractory to conventional mechanical/chemical debridement techniques. The patient had a prohibitively high risk for the operating room but remained too sensate for further effective bedside debridement. Biodebridement was utilized to create a viable wound base, with improved appearance noted within 2 weeks. A review of the current literature shows biodebridement has numerous benefits in the management of chronic wounds. Biodebridement is a unique therapy that possesses great value for select patients in the SICU. In particular, patients who are too high risk for further operative intervention, but too sensate for ongoing bedside debridement and dressing changes, benefit significantly from this underutilized approach. Further research is needed to solidify the place of biodebridement in the surgical management of chronic nonhealing wounds.

Geriatric Trauma Screening Tool: Preinjury Functional Status Dictates Intensive Care Unit Discharge Disposition

Older adults account for an increasing percentage of trauma patients and have worse outcomes when compared with younger populations. Simple prediction tools are needed to designate risk categories among these patients. The Geriatric Trauma Screening Tool (GTST) was developed to risk stratify older adults admitted to the ICU at a Level 1 trauma center. One hundred fifty patients aged ≥ 65 years were prospectively screened for high-risk (HR) injuries, comorbidities, and pre-hospital function using the GTST. Patients who screened for HR were more likely to have an unfavorable disposition than non-HR patients. HR patients had significantly longer ICU and hospital length of stays when compared with non-HR patients. In addition, patients with prior functional impairment were at higher risk for an unfavorable discharge disposition than their counterparts. Implementation of the GTST predicted discharge disposition in geriatric trauma patients admitted to the ICU. Pre-injury functional status was a better predictor of discharge disposition than either the types of HR injuries or the presence of comorbidities. Risk stratification of geriatric trauma patients allows for early engagement of patients and caregivers regarding transitions of care as well as more efficient utilization of hospital resources.

Emergency general surgery in geriatric patients: A statewide analysis of surgeon and hospital volume with outcomes

BACKGROUND

Geriatric patients undergoing emergency general surgery (EGS) face significant morbidity and mortality. We assessed how surgeon and hospital volumes affected these outcomes.

METHODS

We identified patients at least 65 years old in Maryland's Health Services Cost Review Commission database from 2012 to 2014 who underwent one of 12 EGS procedures, as defined by the American Association for the Surgery of Trauma, and then calculated four outcomes: mortality rate, the incidence of at least one of eight common in-hospital EGS complications, failure-to-rescue (death after experiencing a postoperative complication), and the 30-day readmission rate. Median annual volumes of geriatric-EGS procedures divided both surgeons and hospitals into two groups (low volume and high volume). Multivariable logistic regressions calculated associations between the volume groups and outcomes after adjusting for patient, surgeon, and hospital factors, and hospital clusters.

RESULTS

We identified 3,832 patients who had an EGS procedure by 302 surgeons (median: 8 geriatric-EGS/year, IQR: 3-18) at 44 hospitals (median: 82 geriatric-EGS/year, IQR: 35-132). While operating on 16.5% of all geriatric-EGS patients, low-volume surgeons had higher risk-adjusted adverse outcomes: mortality (7.0% vs. 4.0%, p = 0.005), in-hospital complications (22.1% vs. 19.7%, p = 0.13), failure-to-rescue (17.3% vs. 12.1%, p = 0.021), and 30-day readmissions (11.2% vs. 10.0%, p = 0.55). After adjustment, low-volume surgeons were associated with higher mortality (adjusted odds ratio [aOR] 1.86, 95% CI [1.21-2.86]) and failure-to-rescue rates (aOR 1.74 [1.09-2.80]) but not in-hospital complications (aOR 1.20 [0.95-1.51]) or 30-day readmissions (aOR 1.07 [0.85-1.34]). In contrast, low-volume hospitals relative to high-volume hospitals, and hospitals serving lower proportions of geriatric-EGS patients, were not associated with adverse outcomes.

CONCLUSION

Relative to their higher-volume counterparts, surgeons performing eight or fewer geriatric-EGS procedures annually were associated with an 86% higher odds of death and 74% higher odds of failure-to-rescue in this elderly EGS patient population. These findings underscore the need for focused care of elderly surgical patients.

Sarcopenia defined by a computed tomography estimate of the psoas muscle area does not predict frailty in geriatric trauma patients

INTRODUCTION

The aim of our study was to assess the correlation between frailty & sarcopenia and impact of each condition on outcomes in geriatric trauma patients.

METHODS

We performed a four-year (2013-2016) secondary analysis of our prospectively maintained frailty database and included all trauma patients age ≥65 y who had CT-abdomen. Trauma-Specific-Frailty-Index (TSFI) was used to calculate frailty. Patients were classified as non-frail or frail. Sarcopenia was defined as the lowest sex-specific-quartile of total-psoas-index (TPI). Outcome measures included in-hospital complications, mortality and adverse disposition.

RESULTS

325 patients were included in the study, 36% (n = 117) were frail and 24.9% (n = 81) had sarcopenia. There was a weak correlation between frailty and sarcopenia (R² = 0.04). The overall rate of complications and mortality was 19.4% and 7.7% respectively. On regression analysis, after controlling for possible confounding variables and frailty status, sarcopenia was associated with adverse disposition (OR:1.41,p = 0.01). However, it was not associated with in-hospital complications (OR:1.21,p = 0.54) or in-hospital mortality (OR:1.12,p = 0.73).

CONCLUSION

Sarcopenia as an individual marker might not be an effective screening tool for risk assessment in geriatric-trauma patients. Frailty assessment should be a part of risk assessment and prognostication.

Antithrombotics in trauma: management strategies in the older patients

The ageing population has resulted in a change in the demographics of trauma, and older adult trauma now accounts for a growing number of trauma admissions. The management of older adult trauma can be particularly challenging, and exhibits differences to that of the younger age groups affected by trauma. Frailty syndromes are closely related with falls, which are the leading cause of major trauma in older adults. Comorbid disease and antithrombotic use are more common in the older population. Physiological changes that occur with ageing can alter the expected clinical presentation of older persons after injury and their susceptibility to injury. Following major trauma, definitive control of hemorrhage remains essential for improving outcomes. In the initial assessment of an injured patient, it is important to consider whether the patient is taking anticoagulants or antiplatelets and if measures to promote hemostasis such as reversal are indicated. After hemostasis is achieved and bleeding has stopped, longer-term decisions to recommence antithrombotic agents can be challenging, especially in older people. In this review, we discuss one aspect of management for the older trauma patients in greater detail, that is, acute and longer-term management of antithrombotic therapy. As we consider the health needs of an ageing population, rise in elderly trauma and increasing use of antithrombotic therapy, the need for research in this area becomes more pressing to establish best practice and evidence-based care.

Severe trauma in the geriatric population

Geriatric trauma constitutes an increasingly recognized problem. Aging results in a progressive decline in cellular function which leads to a loose of their capacity to respond to injury. Some medications commonly used in this population can mask or blunt the response to injury. Falls constitute the most common cause of trauma and the leading cause of trauma-related deaths in this population. Falls are complicated by the widespread use of antiplatelets and anticoagulants, especially in patients with brain injury. Under-triage is common in this population. Evaluation of frailty could be helpful to solve this issue. Appropriate triaging and early aggressive management with correction of coagulopathy can improve outcome. Limitation of care and palliative measures must be considered in cases with a clear likelihood of poor prognosis.
