Timing and methods of frailty assessments in geriatric trauma patients: A systematic review

Pre-injury frailty and clinical care trajectory of older adults with trauma injuries: A retrospective cohort analysis of A large level I US trauma center

BACKGROUND

Pre-injury frailty among older adults with trauma injuries is a predictor of increased morbidity and mortality.

OBJECTIVES

We sought to determine the relationship between frailty status and the care trajectories of older adult patients who underwent frailty screening in the emergency department (ED).

METHODS

Using a retrospective cohort design, we pooled trauma data from a single institutional trauma database from August 2020 to June 2023. We limited the data to adults 65 years and older, who had trauma injuries and frailty screening at ED presentation (N = 2,862). The predictor variable was frailty status, measured as either robust (score 0), pre-frail (score 1-2), or frail (score 3-5) using the FRAIL index. The outcome variables were measures of clinical care trajectory: trauma team activation, inpatient admission, ED discharge, length of hospital stay, in-hospital death, home discharge, and discharge to rehabilitation. We controlled for age, sex, race/ethnicity, health insurance type, body mass index, Charlson Comorbidity Index, injury type and severity, and Glasgow Coma Scale score. We performed multivariable logistic and quantile regressions to measure the influence of frailty on post-trauma care trajectories.

RESULTS

The mean (SD) age of the study population was 80 (8.9) years, and the population was predominantly female (64%) and non-Hispanic White (60%). Compared to those classified as robust, those categorized as frail had 2.5 (95% CI: 1.86-3.23), 3.1 (95% CI: 2.28-4.12), and 0.3 (95% CI: 0.23-0.42) times the adjusted odds of trauma team activation, inpatient admission, and ED discharge, respectively. Also, those classified as frail had significantly longer lengths of hospital stay as well as 3.7 (1.07-12.62), 0.4 (0.28-0.47), and 2.2 (95% CI: 1.71-2.91) times the odds of in-hospital death, home discharge, and discharge to rehabilitation, respectively.

CONCLUSION

Pre-injury frailty is a predictor of clinical care trajectories for older adults with trauma injuries.

Comparing How Three Frailty Scales Predict Negative Outcomes in Trauma Patients With Rib Fractures

INTRODUCTION

Frailty is a risk factor for adverse outcomes after injury. Herein, we compared three frailty scales: the Canadian Study of Health and Aging clinical frailty scale, the rib fracture frailty index (RFFI) and the modified frailty index-5, to assess which scale is most applicable in predicting risk for negative outcomes in older patients with rib fractures.

METHODS

Patients ≥65 admitted for rib fractures were retrospectively scored for frailty using the RFFI, Canadian Study of Health and Aging clinical frailty scale, and modified frailty index-5. Outcomes examined were in-hospital mortality, pneumonia, in-hospital intubation, hospital length of stay, and discharge to skilled nursing facilities. Areas under the curve, sensitivity, specificity, negative predictive value, and positive predictive value were determined for each frailty scale with each outcome. Agreement was determined using Fleiss' Kappa. P <0.05 was considered significant.

RESULTS

Three hundred forty-one patients were included. All three scales demonstrated similar predictive abilities for the measured outcomes. RFFI predicted mortality and pneumonia 70% of the time. All three scales predicted discharge to skilled nursing facilities 60% of the time. The concordance for all three frailty scales was 241/341 (70.7%). Fleiss Kappa was 0.40 [0.34-0.46] (P < 0.001), indicating a fair to moderate agreement. The predictive ability of all three scales was higher in patients 65-74 y old than in patients ≥75.

CONCLUSIONS

Overall, no scale appeared to significantly outperform the others by areas under the curve estimation. Interrater reliability was higher in the 65 to 74-y-old population compared to the 75 and older population.

Frailty assessment in geriatric trauma patients: comparing the predictive value of the full and a condensed version of the Fried frailty phenotype

BACKGROUND

Frailty is associated with multiple negative outcomes in geriatric trauma patients. Simultaneously, frailty assessment including physical measurements for weakness (grip strength) and slowness (gait speed) poses challenges in this vulnerable patient group. We aimed to compare the full 5-component Fried Frailty Phenotype (fFP) and a condensed model (cFP) without physical measurements, with regard to predicting hospital length of stay (LOS) and discharge disposition (DD).

METHODS

Prospective cohort study in patients aged 70 years and older at a level I trauma center undergoing frailty assessment by 5-component fFP (fatigue, low activity level, weight loss, weakness, and slowness). For the cFP, only fatigue, low activity level and weight loss were included. Co-primary outcomes were LOS and DD.

RESULTS

In 233 of 366 patients, information on all 5 frailty components was available (mean age 81.0 years [SD 6.7], 57.8% women) and included in our comparative analysis. Frailty prevalence was 25.1% and 3.1% by fFP and cFP, respectively. LOS did not differ significantly between frail and non-frail patients, neither using the fFP (p = .245) nor the cFP (p = .97). By the fFP, frail patients were 94% less likely to be discharged home independently (OR 0.06; 95% CI 0.007-0.50, p = .0097), while using cFP, none of the frail patients were discharged home independently.

CONCLUSION

The fFP appears superior in identifying frail trauma patients and predicting their discharge destination compared with the condensed version. LOS in this vulnerable patient group did not differ by either frailty phenotype even if compared with those identified as non-frail.

Predicting the time of mortality among older adult trauma patients: Is frailty the answer?

INTRODUCTION

This study aims to evaluate the temporal trends of mortality among frail versus non-frail older adult trauma patients during index hospitalization.

METHODS

We performed a 3-year (2017-2019) analysis of ACS-TQIP. We included all older adult (age ≥65 years) trauma patients. Patients were stratified into two groups (Frail vs. Non-Frail). Outcomes were acute (<24 ​h), early (24-72 ​h), intermediate (72 hours-1 week), and late (>1 week) mortality.

RESULTS

A total of 1,022,925 older adult trauma patients were identified, of which 19.7 ​% were frail. The mean(SD) age was 77(8) years and 57.4 ​% were female. Median[IQR] ISS was 9[4-10] and both groups had comparable injury severity (p ​= ​0.362). On multivariable analysis, frailty was not associated with acute (aOR 1.034; p ​= ​0.518) and early (aOR 1.190; p ​= ​0.392) mortality, while frail patients had independently higher odds of intermediate (aOR 1.269; p ​= ​0.042) and late (aOR 1.835; p ​< ​0.001) mortality. On sub-analysis, our results remained consistent in mild, moderate, and severely injured patients.

CONCLUSION

Frailty is an independent predictor of mortality in older adult trauma patients who survive the initial 3 days of admission, regardless of injury severity.

The Effect of Frailty in Predicting Outcomes of Rib Fractures Among Elderly Patients

INTRODUCTION

Rib fractures are consequential injuries for geriatric trauma patients. Frailty has been associated with adverse outcomes in this population. The Rib Fracture Frailty Index (RFF) and 5-factor modified Frailty Index (mFI) are 2 validated frailty metrics. Research assessing inclusion of frailty metrics in geriatric rib fractures triage protocols is limited.

METHODS

A retrospective cohort study was performed for trauma patients ≥50 years old with rib fractures admitted to a Level I trauma center, which currently uses percent predicted forced vital capacity (FVC%) to triage rib fractures patients. Frailty metrics (RFF & mFI) were calculated retrospectively, stratifying patients as low, moderate, or severe frailty. Unfavorable discharge disposition (UDD) was defined as discharge to facility or death. Unadjusted and adjusted odds ratios were used to assess frailty with outcome variables.

RESULTS

In total, 834 patients were included from August 2018 - May 2023, with mean age of 69.1. A majority had low frailty (64.0 vs 40.3%), followed by moderate frailty (21.1 vs 30.7%), then severe frailty (14.9 vs 29.0%) for RFF and mFI, respectively. Age, sex, and ISS differed between groups. For RFF, increased frailty was associated with longer hospital and ICU length of stay. Neither frailty metric was associated with unplanned ICU transfer or intubation. In the adjusted analysis, frail patients were more likely to have UDD (OR 8.9, CI 3.4-23.0, P < .0001).

CONCLUSION

While both frailty metrics were predictive of UDD, neither was associated with ICU transfer or intubation, suggesting that frailty does not enhance the accuracy of our current protocol using FVC%.

Reliability and validity of the Chinese version of the trauma-specific frailty index (TSFI) for geriatric trauma patients

BACKGROUND

Pre-traumatic frailty in geriatric trauma patients has caught attention from emergency medical workers and the assessment of it thus become one of the important aspects of risk management. Several tools are available to identify frailty, but limited tools have been validated for geriatric trauma patients in China to assess pre-traumatic frailty.The aim of this study is to translate the Trauma-Specific Frailty Index(TSFI) into Chinese, and to evaluate the reliability and validity of the translated version in geriatric trauma patients.

METHODS

A cross-sectional study was conducted. The TSFI was translated with using the Brislin model, that included forward and backward translation. A total of 184 geriatric trauma patients were recruited by a convenience sampling between October and December 2020 in Hospital of Chengdu University of Traditional Chinese Medicine, Sichuan. Using reliability or internal consistency tests assessed with Cronbach's alpha coefficient, split-half reliability and test-retest reliability. Content validity and construct validity analysis were both performed. Sensitivity, specificity and maximum Youden index(YI) were used to determine the optimal cut-off value. The screening performance was examined by Kappa value.

RESULTS

The total study population included 184 subjects, of which 8 participants were excluded, resulting in a study sample size of 176 elderly trauma patients (the completion rate was 95.7%). The Chinese version of Trauma-Specific Frailty Index(C-TSFI) have 15 items with 5 dimensions. Cronbach's alpha coefficient of the C-TSFI was 0.861, Cronbach's alpha coefficient of dimensions ranged from 0.837 to 0.875, the split-half reliability of the C-TSFI were 0.894 and 0.880 respectively, test-retest reliability ranged from 0.692 to 0.862. The correlation coefficient between items and the C-TSFI ranged from 0.439 to 0.761. The content validity index for items (I-CVI) of the C-TSFI scale was 0.86~1.00, and the scale of content validity index (S-CVI) was 0.93. The area under curve (AUC) of the C-TSFI was 0.932 (95%CI 0.904-0.96, P < 0.05), the maximum YI was 0.725, the sensitivity was 80.2%, the specificity was 92.3%, and the critical value was 0.31. Kappa value was 0.682 (P < 0.05).

CONCLUSIONS

The Chinese version of TSFI could be used as a general assessment tool in geriatric trauma patients, and both its reliability and validity have been demonstrated.

Models of acute care for injured older patients-Australia and New Zealand practice

INTRODUCTION

The epidemiology of injured patients has changed, with an increasing predominance of severe injury and deaths in older (65 years and above) patients after low falls. There is little evidence of the models of care that optimise outcomes for injured older patients. This study aims to describe clinician perspectives of existing models of acute care for injured older patients in Australia and New Zealand.

METHODS

This cross-sectional online survey of healthcare professionals (HCP) managing injured older patients in Australia or New Zealand hospitals was conducted between November 2nd and December 12th, 2020. Recruitment was via survey link and snowball sampling to professional organisations and special interest groups via email and social media. HCP were asked, using a Likert scale, how likely four typical case vignettes were to be admitted to one of twelve options for ongoing care. Additional questions explored usual care components.

RESULTS

Participants (n=157) were predominantly Australian medical professionals in a major trauma service (MTS) or metropolitan hospital. The most common age defining "geriatric" was aged 65 years and older (43%). HCP described variability in the models and components of acute care for older injured patients in Australia and New Zealand. As a component of care, cognitive, delirium and frailty screening are occurring (60%, 61%, 46%) with HCP from non-major trauma services (non-MTS) reporting frailty and cognitive impairment screening more likely to occur in the emergency department (ED). Access to an acute pain service was more likely in a MTS. Participants described poor likelihood of a geriatrician (highest 16%) or physician (highest 12%) review in ED CONCLUSION: Despite a low response rate, HCP in Australia and New Zealand describe variability in acute care pathways for injured older patients. Given the change in epidemiology of injury towards older patients with low force mechanisms, models of acute injury care should be evaluated to define a cost-effective model and components of care that optimise patient-centred outcomes relevant to injured older patients. HCP described some factors they perceive to determine care, and outcomes of variability, offering guidance for future research and resource allocation in the Australia and New Zealand trauma system.

Frailty and emergency surgery: identification and evidence-based care for vulnerable older adults

Frailty is a multidimensional state related to accumulation of age- and disease-related deficits across multiple domains. Older people represent the fastest growing segment of the peri-operative population, and 25-50% of older surgical patients live with frailty. When frailty is present before surgery, adjusted rates of morbidity and mortality increase at least two-fold; the odds of delirium and loss of independence are increased more than four- and five-fold, respectively. Care of the older person with frailty presenting for emergency surgery requires individualised and evidence-based care given the high-risk and complex nature of their presentations. Before surgery, frailty should be assessed using a multidimensional frailty instrument (most likely the Clinical Frailty Scale), and all members of the peri-operative team should be aware of each patient's frailty status. When frailty is present, pre-operative care should focus on documenting and communicating individualised risk, considering advanced care directives and engaging shared decision-making when feasible. Shared multidisciplinary care should be initiated. Peri-operatively, analgesia that avoids polypharmacy should be provided, along with delirium prevention strategies and consideration of postoperative care in a monitored environment. After the acute surgical episode, transition out of hospital requires that adequate support be in place, along with clear discharge instructions, and review of new and existing prescription medications. Advanced care directives should be reviewed or initiated in case of readmission. Overall, substantial knowledge gaps about the optimal peri-operative care of older people with frailty must be addressed through robust, patient-oriented research.

Long term outcomes following rib fracture fixation in patients with major chest trauma

BACKGROUND

Severe chest injuries are associated with significant morbidity and mortality. Surgical rib fixation has become a more commonplace procedure to improve chest wall mechanics, pain, and function. The aim of this study was to characterise the epidemiology and long-term functional outcomes of chest trauma patients who underwent rib fixation in a major trauma centre (MTC).

METHODOLOGY

This was a retrospective review (2014-19) of all adult patients with significant chest injury who had rib fixation surgery following blunt trauma to the chest. The primary outcome was functional recovery after hospital discharge, and secondary outcomes included length of intensive care unit (ICU) and hospital stay, maximum organ support, tracheostomy insertion, ventilator days.

RESULTS

60 patients underwent rib fixation. Patients were mainly male (82%) with median age 52 (range 24-83) years, injury severity score (ISS) of 29 (21-38), 10 (4-19) broken ribs, and flail segment in 90% of patients. Forty-six patients (77%) had a good outcome (GOSE grade 6-8). Patients in the poor outcome group (23%; GOSE 1-5) tended to be older [55 (39-83) years vs. 51 (24-78); p = 0.05] and had longer length of hospital stay [42 (19-82) days vs. 24 (7-90); p<0.01]. Injury severity, rate of mechanical ventilation or organ dysfunction did not affect long term outcome. Nineteen patients (32%) were not mechanically ventilated.

CONCLUSIONS

Rib fixation was associated with good long-term outcomes in severely injured patients. Age was the only predictor of long-term outcome. The results suggest that rib fixation be considered in patients with severe chest injuries and may also benefit those who are not mechanically ventilated but are at risk of deterioration.

Acute traumatic brain injury in frail patients: the next pandemic

PURPOSE OF REVIEW

To highlight recent findings on the evaluation and impact of frailty in the management of patients with traumatic brain injury (TBI).

RECENT FINDINGS

Frailty is not a direct natural consequence of aging. Rather, it commonly results from the intersection of age-related decline with chronic diseases and conditions. It is associated with adverse outcomes such as institutionalization, falls, and worsening health status. Growing evidence suggests that frailty should be a key consideration both in care planning and in adverse outcome prevention. The prevalence of elderly patients with TBI is increasing, and low-energy trauma (i.e., ground or low-level falls, which are typical in frail patients) is the major cause. Establishing the real incidence of frailty in TBI requires further studies. Failure to detect frailty potentially exposes patients to interventions that may not benefit them, and may even harm them. Moreover, considering patients as 'nonfrail' purely on the basis of their age is unacceptable. The future challenge is to shift to a new clinical paradigm characterized by more appropriate, goal-directed care of frail patients.

SUMMARY

The current review highlights the crucial importance of frailty evaluation in TBI, also given the changing epidemiology of this condition. To ensure adequate assessment, prevention and management, both in and outside hospital, there is an urgent need for a valid screening tool and a specific frailty-based and comorbidity-based clinical approach.

Predicting mortality in elderly trauma patients: a review of the current literature

PURPOSE OF REVIEW

Advances in medical care allow patients to live longer, translating into a larger geriatric patient population. Adverse outcomes increase with older age, regardless of injury severity. Age, comorbidities, and physiologic deterioration have been associated with the increased mortality seen in geriatric trauma patients. As such, outcome prediction models are critical to guide clinical decision making and goals of care discussions for this population. The purpose of this review was to evaluate the various outcome prediction models for geriatric trauma patients.

RECENT FINDINGS

There are several prediction models used for predicting mortality in elderly trauma patients. The Geriatric Trauma Outcome Score (GTOS) is a validated and accurate predictor of mortality in geriatric trauma patients and performs equally if not better to traditional scores such as the Trauma and Injury Severity Score. However, studies recommend medical comorbidities be included in outcome prediction models for geriatric patients to further improve performance.

SUMMARY

The ideal outcome prediction model for geriatric trauma patients has not been identified. The GTOS demonstrates accurate predictive ability in elderly trauma patients. The addition of medical comorbidities as a variable in outcome prediction tools may result in superior performance; however, additional research is warranted.

The feasibility and reliability of frailty assessment tools applicable in acute in-hospital trauma patients: A systematic review

BACKGROUND

Assessing frailty in patients with an acute trauma can be challenging. To provide trustworthy results, tools should be feasible and reliable. This systematic review evaluated existing evidence on the feasibility and reliability of frailty assessment tools applied in acute in-hospital trauma patients.

METHODS

A systematic search was conducted in relevant databases until February 2020. Studies evaluating the feasibility and/or reliability of a multidimensional frailty assessment tool used to identify frail trauma patients were identified. The feasibility and reliability results and the risk of bias of included studies were assessed. This study was conducted and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and registered in Prospective Register of Systematic Reviews (ID: CRD42020175003).

RESULTS

Nineteen studies evaluating 12 frailty assessment tools were included. The risk of bias of the included studies was fair to good. The most frequently evaluated tool was the Clinical Frailty Scale (CFS) (n = 5). All studies evaluated feasibility in terms of the percentage of patients for whom frailty could be assessed; feasibility was high (median, 97%; range, 49-100%). Other feasibility aspects, including time needed for completion, tool availability and costs, availability of instructions, and necessity of training for users, were hardly reported. Reliability was only assessed in three studies, all evaluating the CFS. The interrater reliability varied between 42% and >90% agreement, with a Krippendorff α of 0.27 to 0.41.

CONCLUSION

Feasibility of most instruments was generally high. Other aspects were hardly reported. Reliability was only evaluated for the CFS with results varying from poor to good. The reliability of frailty assessment tools for acute trauma patients needs further critical evaluation to conclude whether assessment leads to trustworthy results that are useful in clinical practice.

Rib Fracture Frailty Index: A risk stratification tool for geriatric patients with multiple rib fractures

BACKGROUND

Rib fractures are consequential injuries for geriatric patients (age, ≥65 years). Although age and injury patterns drive many rib fracture management decisions, the impact of frailty-which baseline conditions affect rib fracture-specific outcomes-remains unclear for geriatric patients. We aimed to develop and validate the Rib Fracture Frailty (RFF) Index, a practical risk stratification tool specific for geriatric patients with rib fractures. We hypothesized that a compact list of frailty markers can accurately risk stratify clinical outcomes after rib fractures.

METHODS

We queried nationwide US admission encounters of geriatric patients admitted with multiple rib fractures from 2016 to 2017. Partitioning around medoids clustering identified a development subcohort with previously validated frailty characteristics. Ridge regression with penalty for multicollinearity aggregated baseline conditions most prevalent in this frail subcohort into RFF scores. Regression models with adjustment for injury severity, sex, and age assessed associations between frailty risk categories (low, medium, and high) and inpatient outcomes among validation cohorts (odds ratio [95% confidence interval]). We report results according to Transparent Reporting of Multivariable Prediction Model for Individual Prognosis guidelines.

RESULTS

Development cohort (n = 55,540) cluster analysis delineated 13 baseline conditions constituting the RFF Index. Among external validation cohort (n = 77,710), increasing frailty risk (low [reference group], moderate, high) was associated with stepwise worsening adjusted odds of mortality (1.5 [1.2-1.7], 3.5 [3.0-4.0]), intubation (2.4 [1.5-3.9], 4.7 [3.1-7.5]), hospitalization ≥5 days (1.4 [1.3-1.5], 1.8 [1.7-2.0]), and disposition to home (0.6 [0.5-0.6], 0.4 [0.3-0.4]). Locally weighted scatterplot smoothing showed correlations between increasing RFF scores and worse outcomes.

CONCLUSION

The RFF Index is a practical frailty risk stratification tool for geriatric patients with multiple rib fractures. The mobile app we developed may facilitate rapid implementation and further validation of RFF Index at the bedside.

Health Services Use and Functional Recovery Following Blunt Trauma in Older Persons - A National Multicentre Prospective Cohort Study

OBJECTIVE

Frailty is associated with morbidity and mortality in older injured patients. However, for older blunt-trauma patients, increased frailty may not manifest in longer length of stay at index admission. We hypothesized that owing to time spent in hospital from readmissions, frailty would be associated with less total time at home in the 1-year postinjury period.

DESIGN

Prospective, nationwide, multicenter cohort study.

SETTING AND PARTICIPANTS

All Singaporean residents aged ≥55 years admitted for blunt trauma with an Injury Severity Score (ISS) or New Injury Severity Score (NISS) ≥10 from March 2016 to July 2018.

METHODS

Frailty (by modified Fried criteria) was assessed at index admission, based on questions on preinjury weight loss, slowness, exhaustion, physical activity, and grip strength at the time of recruitment. Low time at home was defined as >14 hospitalized days within 1 year postinjury. The contribution of planned and unplanned readmission to time at home postinjury was explored. Functional trajectory (by Barthel Index) over 1 year was compared by frailty.

RESULTS

Of the 218 patients recruited, 125 (57.3%) were male, median age was 72 years, and 48 (22.0%) were frail. On univariate analysis, frailty [relative to nonfrail: odds ratio (OR) 3.45, 95% confidence interval (CI) 1.33-8.97, P = .01] was associated with low time at home. On multivariable analysis, after inclusion of age, gender, ISS, intensive care unit admission, and surgery at index admission, frailty (OR 5.21, 95% CI 1.77-15.34, P < .01) remained significantly associated with low time at home in the 1-year postinjury period. Unplanned readmissions were the main reason for frail participants having low time at home. Frail participants had poorer function in the 1-year postinjury period.

CONCLUSIONS AND IMPLICATIONS

In the year following blunt trauma, frail older patients experience lower time at home compared to patients who were not frail at baseline. Screening for frailty should be considered in all older blunt-trauma patients, with a view to being prioritized for postdischarge support.

Predicting 1 year mortality after traumatic injury using the Clinical Frailty Scale

BACKGROUND

Frailty is known to affect how people admitted with traumatic injuries recover during their inpatient stay and shortly after discharge. However, few studies have examined the effect of frailty on long-term mortality when adjusted for significant factors including age. We aimed to determine the effect of frailty on 1-year morality in older adults admitted with traumatic injuries.

METHODS

We undertook an observational study at the Severn Major Trauma Network's major trauma centre based in South West England. Patients ≥65 years old admitted between November 2018 and September 2019 with traumatic injuries were included. Isolated hip fractures and inpatient injuries were excluded. A geriatrician assessed all patients for frailty using the Clinical Frailty Scale. Follow-up occurred at 1 year. A multivariable Cox proportional baseline hazards model assessed the effect of frailty on time-to-mortality. The adjusted model included age, sex, multimorbidity, surgery, most injured site, injury severity, postinjury complications, and geriatrician review.

RESULTS

Five hundred and eighty-five patients were included. Median age was 81 years old (IQR 74-88), and median injury severity score was 13 (IQR 9-25). At 1 year 147 (25.1%) patients had died. Living with frailty was associated with mortality. The risk of dying increased with frailty severity. Compared to CFS 1-3: CFS 4 aHR = 1.73 (95% CI 0.89-3.36, p = 0.11); CFS 5 aHR = 3.82 (95% CI 2.11-6.93, p < 0.001); CFS 6 aHR = 4·05 (95% CI 2.21-7.45, p < 0.001); CFS 7-8 aHR = 6.57 (95% CI 3.43-12.59, p < 0.001).

CONCLUSION

This study is the first to demonstrate a consistent effect of frailty, at all levels of severity and independent of age, on older peoples' survival 1 year after traumatic injury. These data support performing an admission frailty assessment to aid long-term management decisions and provide opportunity to modify frailty to improve outcomes.

A new tool to measure acuity in the community: a case study

The provision of acute healthcare within patients own home (i.e. hospital in the home) is an important method of providing individualised patient-centred care that reduces the need for acute hospital admissions and enables early hospital discharge for appropriate patient groups. The Hospital in the Home (HitH) model of care ensures that this approach maximises patient safety and limits potential risk for patients. As HitH services have seen record numbers of patient referrals in the past 2 years, there is now a greater need to measure and understand the acuity and dependency levels of the caseload. Through an expert clinician development process at one NHS trust, aspects of procedural complexity, interdisciplinary working, risk stratification and comorbidities were used to quantify acuity and dependency. This paper uses a case study approach to present a new method of measuring this important concept.

Unseen Burden of Injury: Post-Hospitalization Mortality in Geriatric Trauma Patients

BACKGROUND/OBJECTIVES

Older adults are at risk for adverse outcomes after trauma, but little is known about post-acute survival as state and national trauma registries collect only inpatient or 30-day outcomes. This study investigates long-term, out-of-hospital mortality in geriatric trauma patients.

METHODS

Level I Trauma Center registry data were matched to the US Social Security Death Index (SSDI) to determine long-term and out-of-hospital outcomes of older patients. Blunt trauma patients aged ≥65 were identified from 2009 to 2015 in an American College of Surgeons Level 1 Trauma Center registry, n = 6289 patients with an age range 65-105 years, mean age 78.5 ± 8.4 years. Dates of death were queried using social security numbers and unique patient identifiers. Demographics, injury, treatments, and outcomes were compared using descriptive and univariate statistics.

RESULTS

Of 6289 geriatric trauma patients, 505 (8.0%) died as an inpatient following trauma. Fall was the most common mechanism of injury (n = 4757, 76%) with mortality rate of 46.5% at long-term follow-up; motor vehicle crash (MVC) (n = 1212, 19%) had long-term mortality of 27.6%. Overall, 24.1% of patients died within 1 year of trauma. Only 8 of 488 patients who died between 1 and 6 months post-trauma were inpatient. Mortality rate varied by discharge location: 25.1% home, 36.4% acute rehabilitation, and 51.5% skilled nursing facility, P < .0001.

CONCLUSION

Inpatient and 30-day mortality rates in national outcome registries fail to fully capture the burden of trauma on older patients. Though 92% of geriatric trauma patients survived to discharge, almost one-quarter had died by 1 year following their injuries.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

The processes of hospital discharge and recovery after blunt thoracic injuries: The patient's perspective

AIMS

The aim of this study was to explore hospital discharge processes and the self-management of recovery in the early post-discharge period after blunt thoracic injury from a patient perspective.

DESIGN

Qualitative interview study.

METHODS

Interviews were conducted with participants recruited from 8 sites across England and Wales between November 2019-May 2020. Semi-structured interviews were conducted between 5-8 weeks after hospital discharge, and in total, 14 interviews were undertaken. These interviews were recorded, transcribed and analysed using thematic coding.

RESULTS

Three main themes were identified from the analysis: (a) challenges in the discharge process, (b) coping at home after discharge and (c) managing medications at home. Pain was a dominant thread running throughout all themes which represented an important quality and safety concern for all participants. Associated concerns included insufficient preparation and education for hospital discharge, ineffective communication and subsequent unsafe use of opioids at home highlighting unmet patient care needs.

Feasibility and accuracy of ED frailty identification in older trauma patients: a prospective multi-centre study

BACKGROUND

The burden of frailty on older people is identifiable by its adverse effect on mortality, morbidity and long term functional and health outcomes. In patients suffering from a traumatic injury there is increasing evidence that it is frailty rather than age that impacts greatest on these outcomes and that early identification can guide frailty specific care. The aim of this study was to evaluate the feasibility of nurse-led assessment of frailty in older trauma patients in the ED in patients admitted to major trauma centres.

METHODS

Patients age 65 years and over attending the Emergency Departments (ED) of five Major Trauma Centres following traumatic injury were enrolled between June 2019 and March 2020. Patients were assessed for frailty whilst in the ED using three different screening tools (Clinical Frailty Scale [CFS], Program of Research to Integrate Services for the Maintenance of Autonomy 7 [PRIMSA7], and the Trauma Specific Frailty Index [TSFI]) to compare feasibility and accuracy. Accuracy was determined by agreement with geriatrician assessment of frailty. The primary outcome was identification of frailty in the ED using three different assessment tools.

RESULTS

We included 372 patients whose median age was 80, 53.8% of whom were female. The most common mechanism of injury was fall from less than 2 m followed by falls greater than 2 m. Completion rates for the tools were variable, 31.9% for TSFI, compared to 93% with PRISMA7 and 98.9% with the CFS. There was substantial agreement when using CFS between nurse defined frailty and geriatrician defined frailty. Agreement was moderate using PRISMA7 and slight using TSFI.

CONCLUSIONS

This prospective study has demonstrated that screening for frailty in older major trauma patients within the Emergency Department is feasible and accurate using CFS.

Racial and Ethnic Disparities in Frail Geriatric Trauma Patients

Background

Frailty in geriatric trauma patients is commonly associated with adverse outcomes. Racial disparities in geriatric trauma patients are previously described in the literature. We aimed to assess whether race and ethnicity influence outcomes in frail geriatric trauma patients.

Methods

We performed a 1-year (2017) analysis of TQIP including all geriatric (age ≥ 65 years) trauma patients. The frailty index was calculated using 11-variables and a cutoff limit of 0.27 was defined for frail status. Multivariate regression analysis was performed to control for demographics, insurance status, injury parameters, vital signs, and ICU and hospital length of stay.

Results

We included 41,111 frail geriatric trauma patients. In terms of race, among frail geriatric trauma patients, 35,376 were Whites and 2916 were African Americans; in terms of ethnicity, 37,122 were Non-Hispanics and 2184 were Hispanics. On regression analysis, the White race was associated with higher odds of mortality (OR, 1.5; 95% CI, 1.2–2.0; p < 0.01) and in-hospital complications (OR, 1.4; 95% CI, 1.1–1.9; p < 0.01). White patients were more likely to be discharged to SNF (OR, 1.2; 95% CI, 1.1–1.4; p = 0.03) and less likely to be discharged home (p = 0.04) compared to African Americans. Non-Hispanics were more likely to be discharged to SNF (OR, 1.3; 95% CI, 1.1–1.5; p < 0.01) and less likely to be discharged home (p < 0.01) as compared to Hispanics. No significant difference in in-hospital mortality was seen between Hispanics and Non-Hispanics.

Conclusion

Race and ethnicity influence outcomes in frail geriatric trauma patients. These disparities exist regardless of age, gender, injury severity, and insurance status. Further studies are needed to highlight disparities by race and ethnicity and to identify potentially modifiable risk factors in the geriatric trauma population.

Geriatric ATV and snowmobile trauma at a rural level 1 trauma center: A blow to the chest

INTRODUCTION

As the population ages, trauma centers are seeing a significant volume of injured geriatric patients. However, there is limited data on geriatric off-roading incidents. We investigated the injury patterns, severity and outcomes of geriatric versus younger adult all-terrain vehicle (ATV) and snowmobile related trauma with the hypothesis that geriatric patients will have higher mortality and worsened outcomes.

METHODS

The trauma registry at a New England Level 1 trauma center was queried by ICD 9/10 code for adult ATV and/or snowmobile-related trauma from 2011-2019. Data reviewed included demographic, admission, injury, and outcomes data including injury severity score (ISS), abbreviated injury scale (AIS) score, hospital disposition, and mortality. Patients were stratified by age into younger adults (18-64 years old) versus geriatric (65 years and older). Univariate analysis was performed to compare groups.

RESULTS

Over the study period, we identified 390 adult ATV or snowmobile-related trauma patients, of whom 38 were geriatric. The mean ages for the younger adult vs. geriatric cohorts were 41(SD 13) and 73(SD 5), respectively. The majority of patients were male (77%). Compared to younger adults, geriatric patients were more often unhelmeted (66 v 38%, p=0.004) and more likely to present after ATV as opposed to snowmobile trauma (71 v 51%, p=0.028). Geriatric patients more often sustained both any chest trauma (68 v 41%, p=0.003) and severe chest trauma (AIS≥3, 55 v 31%, p=0.022), and more often required tube thoracostomy (26 v 12%, p=0.042). Geriatric patients were also more often discharged to a facility (39 v 14%, p<0.001) compared to younger patients. There were no differences between age cohorts regarding arrival Glasgow coma scale scores, ISS>15, length of stay, ventilator days, complications, or mortality.

CONCLUSIONS

Following ATV or snowmobile-related trauma, geriatric patients were more likely to sustain severe chest trauma and to require additional care upon hospital discharge as compared to younger adults. Primary prevention should focus on encouraging helmet and chest protective clothing use in this geriatric population.

The impact of frailty on posttraumatic outcomes in older trauma patients: A systematic review and meta-analysis

BACKGROUND

Frailty is a risk factor for mortality among the elderly. However, evidence from longitudinal studies linking trauma and frailty is fragmented, and a comprehensive analysis of the relationship between frailty and adverse outcomes is lacking. Therefore, we conducted a systematic review and meta-analysis to examine whether frailty is predictive of posttraumatic results including mortality, adverse discharge, complications, and readmission in trauma patients.

METHODS

This systematic review was registered with the PROSPERO international prospective register of systematic reviews. Articles in PubMed, Embase, and Web of Science databases from January 1, 1990, to October 31, 2019, were systematically searched. Articles in McDonald et al.'s study (J Trauma Acute Care Surg. 2016;80(5):824-834) and Cubitt et al.'s study (Injury 2019;50(11):1795-1808) were included for studies evaluating the association between frailty and outcomes in trauma patients. Cohort studies, both retrospective and prospective, were included. Study population was patients suffering trauma injuries with an average age of 50 years and older. Multivariate adjusted odds ratios (ORs) were calculated through a random-effects model, and the Newcastle-Ottawa Quality Assessment Scale was used to assess studies.

RESULTS

We retrieved 11,313 entries. Thirteen studies including seven prospective and six retrospective cohort studies involving 50,348 patients were included in the meta-analysis. Frailty was a significant predictor of greater than 30-day mortality (OR, 2.41; 95% confidence interval [CI], 1.17-4.95; I = 88.1%), in-hospital and 30-day mortality (OR, 4.05; 95% CI, 2.02-8.11; I = 0%), postoperative complications (OR, 2.23; 95% CI, 1.34-3.73; I = 78.2%), Clavien-Dindo IV complications (OR, 4.16; 95% CI, 1.70-10.17; I = 0%), adverse discharge (OR, 1.80; 95% CI, 1.15-2.84; I = 78.6%), and readmission (OR, 2.16; 95% CI, 1.19-3.91; I = 21.5%) in elderly trauma patients. Subgroup analysis showed that prospective studies (OR, 3.06; 95% CI, 1.43-6.56) demonstrated a greater correlation between frailty and postoperative complications.

CONCLUSION

Frailty has significant adverse impacts on the occurrence of posttraumatic outcomes. Further studies should focus on interventions for patients with frailty. Given the number of vulnerable elderly trauma patients grows, further studies are needed to determine the accuracy of these measures in terms of trauma outcomes.
