New horizons in rib fracture management in the older adult

Clinical outcome analysis for surgical fixation versus conservative treatment on rib fractures: a systematic evaluation and meta-analysis

BACKGROUND

The efficacy of surgical intervention for traumatic rib fractures in improving clinical outcomes remains a subject of considerable debate. Over the past decade, the adoption of surgical stabilization for rib fractures (SSRF) has increased substantially. This study presents a systematic review and meta-analysis of the literature published over the past 20 years, with the objective of comparing the clinical outcomes of adult patients with multiple traumatic rib fractures who underwent SSRF, relative to those treated conservatively.

METHODS

We searched six online databases (PubMed, Web of Science, Embase, Cochrane Library, and the Sino-American Clinical Trials Database) for literature published between June 2004 and June 2024. The Cochrane Collaboration Risk of Bias 2 (RoB 2) and the Newcastle-Ottawa Scale (NOS) tool were employed to assess methodological quality, and relative risks (RR) with 95% confidence intervals (CI) were calculated to evaluate the outcome measures. The primary outcome was all-cause mortality, while the secondary outcomes included hospital length of stay (HLOS), ICU length of stay (ILOS), duration of mechanical ventilation (DMV), and the incidence of pneumonia. Subgroup analyses were performed to assess the effects of fracture type, age, timing of surgical fixation, and study design on treatment outcomes.

RESULTS

A total of 47 studies involving 1,078,795 patients were included, consisting of three randomized controlled trials and 44 case-control studies. The results demonstrated that patients who underwent SSRF experienced better outcomes than those receiving conservative treatment in terms of all-cause mortality. However, SSRF was not superior to conservative treatment regarding HLOS, ILOS, or health care costs. Subgroup analyses revealed that the SSRF group had a lower incidence of pneumonia and shorter DMV in patients with flail chest, and patients older than 60 years may also benefit from SSRF, Furthermore, those who underwent SSRF within 72 h had shorter HLOS and DMV compared to those treated conservatively.

CONCLUSION

SSRF reduces mortality in patients with multiple rib fractures compared to conservative management, particularly in those with flail chest and in patients over 60 years of age. It also offers benefits in terms of pneumonia incidence and DMV for patients with flail chest. Early SSRF may significantly reduce HLOS and DMV. However, careful screening of appropriate candidates is crucial to maximize the benefits of SSRF.

Surgical stabilisation of rib fractures in non-ventilated patients: a retrospective propensity-matched analysis using the data from the trauma registry of the German Trauma Society (TraumaRegister DGUⓇ)

PURPOSE

Severe thorax trauma including multiple rib fractures and flail chest deformity are leading causes of death in trauma patients. Increasing evidence supports the use of surgical stabilisation of rib fractures (SSRF) in these patients. However, there is currently a paucity of evidence for its use in non-ventilator-dependent patients.

METHODS

A retrospective propensity-matched analysis of the data of the TraumaRegister DGU® for non-ventilator-dependent patients with severe rib injury (abbreviated injury score ≥ 3) was performed. Subgroup analyses with respect to injury severity score, American society of anaesthesiologists physical status classification and age were performed. Furthermore, the effect of time to surgery was analysed.

REGISTRATION

TR-DGU project ID 2023-007; ClinicalTrials.gov protocol ID: NCT06464289.

RESULTS

SSRF led to reduced mortality compared to conservative treatment (1.6% vs. 4.8%; p = 0.002) and in comparison to the mortality prognosis of the revised injury severity classification II (RISC II) of 5.2%. Interestingly, SSRF was associated with increased length of hospital and intensive care unit stay, higher rates of organ failure and secondary intubation. The patients with organ failure received SSRF later than those without organ failure.

CONCLUSION

Here we report on the largest currently published dataset of non-intubated patients receiving SSRF, which showed reduced mortality in the SSRF cohort. The data indicates that SSRF is a viable treatment option for non-intubated patients. The observed late surgical time points, which may be due to cross over after failed conservative treatment, might be the cause for the observed increased rate of organ failure.

Non-Completely Displaced Traumatic Rib Fractures: Potentially Less Crucial for Pulmonary Adverse Outcomes, Regardless of Classification

Background and Objectives: Two major classification systems exist for rib fracture (RFX) displacement. One system uses a 50% displacement threshold: Grade I (<50%), Grade II (≥50% to <100%), and Grade III (completely dislocated). Another proposes a 10% threshold: Undisplaced (<10%), Offset (≥10% to <100%), and Displaced (completely dislocated). We analyzed risk factors for adverse outcomes for pulmonary complications and mortality according to both classification criteria. Materials and Methods: We retrospectively reviewed trauma registry and medical records from January 2019 to December 2023. All radiographic parameters were recorded based on initial computed tomography. Primary outcomes were pneumonia and other pulmonary complications requiring surgery. Least absolute shrinkage and selection operator (LASSO) regression was conducted to select risk factors and minimize overfitting. Multivariable logistic regression (MLR) was performed after LASSO. Results: Among the 621 patients, 61 (9.8%) had one or more adverse outcomes. In MLR, regardless of both classifications, the age (p < 0.001), ISS (p < 0.001), and number of completely displaced RFX (p = 0.001) were statistically significant. After excluding 280 patients with completely displaced RFX, we conducted a subgroup analysis with the remaining 341 patients. In this analysis, 22 (6.5%) patients experienced one or more adverse outcomes. Regardless of both classifications, the AIS head (p = 0.006), AIS extremities (p = 0.012), and number of segmental RFX (p < 0.001) were statistically significant in MLR. The area under the receiver operating curve for both MLR models was 0.757 in the total patient group and 0.823 in the subgroup that excluded patients with completely displaced RFX. Conclusions: Completely displaced RFX is the most crucial factor, regardless of the classification criteria. Unless ribs are completely displaced, the degree of displacement may not be crucial, and the number of segmental RFX was a significant risk factor.

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.

Analysis of risk factors for poor healing and long-duration pain in conservative treatment of rib fractures

Rib fractures are a common injury following blunt chest trauma, accounting for approximately 10% of all traumatic injuries and up to 50% of blunt chest trauma cases. These fractures are associated with a high risk of complications, such as pneumothorax, hemothorax, and pulmonary infections, and can significantly impact respiratory function. This study analyzes the risk factors for poor healing and long-duration pain in the conservative treatment of rib fractures, providing a reference for clinicians in choosing conservative treatment and formulating treatment plans. A retrospective analysis was conducted on 342 patients who underwent conservative treatment for rib fractures from January 2023 to May 2024. Baseline data, clinical data, and follow-up data were collected. Comparisons were made between the poor healing group and the good healing group, as well as between the long-duration pain group and the short-duration pain group in the conservative treatment of rib fractures. Univariate and multivariate logistic regression analyses were performed to identify risk factors for poor healing and long-duration pain. In patients undergoing conservative treatment for rib fractures, the average duration of pain was 12.18 ± 10.78 days, with an incidence of pulmonary complications of 59.06% (202/342) and poor healing rate of 6.43% (22/342). Significant differences were observed between the good and poor healing groups in terms of age (P = .018), presence of coronary heart disease (CHD, P = .023), chronic obstructive pulmonary disease (COPD, P < .001), blood calcium (P = .007), and alkaline phosphatase (P < .001). Similarly, significant differences were found between the long-duration and short-duration pain groups in age (P = .039), presence of diabetes (P < .001), CHD (P < .001), COPD (P < .001), and alkaline phosphatase (P < .001). Multivariate analysis identified COPD (P = .015), blood calcium (P = .013), and alkaline phosphatase (P = .006) as independent risk factors for poor healing, while diabetes (P = .001), CHD (P = .014), and alkaline phosphatase (P < .001) were independent risk factors for prolonged pain duration. COPD, blood calcium, and alkaline phosphatase are independent risk factors for poor healing in conservative treatment of rib fractures. Diabetes, CHD, and alkaline phosphatase are independent risk factors for long-duration pain in conservative treatment of rib fractures.

Efficacy and safety of the serratus anterior plane block (SAP block) for pain management in patients with multiple rib fractures in the emergency department: a retrospective study

PURPOSE

Chest trauma is a severe and frequent cause of admission to the emergency department (ED). The serratus anterior plane (SAP) block seems to be an effective method of pain management; however, data on efficacy and safety of a single SAP block performed in the ED by emergency physicians (EP) are limited. This study aimed to compare SAP block performed by the EP in the ED plus standard therapy to standard therapy alone in terms of pain severity at 0-3-6-12-18 and 24 h, total opioid consumption (milligrams of morphine equivalents, MME), respiratory function (SpO2/FiO2 ratio), and adverse events (i.e. pneumothorax, infections in the site of injection, or Local Anaesthetic Systemic Toxicity syndrome due to SAP block) in the first 24 h.

METHODS

This retrospective, monocentric study included adult patients admitted to the Sub-intensive Care Unit (SICU) of the ED with multiple rib fractures between 01/2022 and 03/2023.

RESULTS

156 patients (65.4% male; median age 62 years; median injury severity score 16; median thoracic trauma severity score 8) were included. 75 (48.2%) underwent SAP block. Patients undergoing SAP block showed significantly less pain 3-6-18 h after a single block, required less MME (0 [0-20] vs. 20 [0-40], p < 0.001), showed higher SpO2/FiO2 ratio, and no adverse events were reported.

CONCLUSION

The SAP block, in combination with standard therapy, appeared to be more effective in providing pain relief than standard therapy alone in patients admitted to the SICU for traumatic rib fractures.

Long-term trends in incidence and outcomes of rib fractures: A population-based data linkage study from New South Wales, Australia

OBJECTIVE

Determine long-term trends in population-based incidence and outcomes of rib fracture hospitalisations.

METHODS

This was a data linkage study of rib fracture cases identified between 2015 and 2022 in New South Wales, Australia. Routinely collected health data were linked between ED, admitted patient and death registry data collection. The primary outcomes were age-specific incidence of rib fracture hospitalisation cases and risk-adjusted 30 days mortality. Other outcomes of interest were hospital length of stay (LOS), admission rate and ICU admissions.

RESULTS

A total of 70 609 cases were analysed. Overall, the number of rib fracture hospitalisations increased by 25% between 2015 and 2022. The highest proportion of cases was in the 45-65 years (28%) and 65-85 years (31%) age groups. On a per population basis, the incidence rate increased by 2% per annum. After adjusting for age, comorbidity and injury severity, there was no significant trend in 30 days mortality observed between 2015 and 2022. The median inpatient LOS was 4 days with 38% of patients staying 1-2 days. Regional and rural areas were associated with more severe chest injuries.

CONCLUSION

Rib fracture hospitalisations have increased with older patients driving this trend.

Age-Neutral Surgical Stabilization of Rib Fractures: Breaking the Ageism Barrier

INTRODUCTION

Surgical stabilization of rib fractures (SSRF) is associated with lower rates of mortality and fewer complications. This study evaluates whether the decision to undergo SSRF is associated with age, race, ethnicity, and insurance status and assesses associated clinical outcomes.

METHODS

This retrospective analysis included patients ≥45 y old with rib fractures who underwent SSRF in the Trauma Quality Improvement Program from 2016 to 2020. Race, ethnicity, and insurance statuses were collected. Age in years was dichotomized into two groups: 45-64 and 65+. Outcomes included ventilator-associated pneumonia, unplanned endotracheal intubation, acute respiratory distress syndrome, in-hospital mortality, failure to rescue (FTR) after major complications, and FTR after respiratory complications. Logistic regression models were fit to evaluate outcomes, controlling for gender, body mass index, Injury Severity Score, flail chest, chronic obstructive pulmonary disease, congestive heart failure, and smoking.

RESULTS

Two thousand eight hundred thirty-nine patients aged 45-64 and 1828 patients aged 65+ underwent SSRF. No significant difference in clinical outcomes was noted between these groups. Analysis showed that the association of SSRF with ventilator-associated pneumonia, unplanned intubation, acute respiratory distress syndrome, in-hospital mortality, FTR after a major complication, or FTR after a respiratory complication did not vary by age (P > 0.05). Black (odds ratio [OR] 0.67; 95% confidence interval [CI]: 0.59-0.77; P < 0.001), Hispanic (OR 0.80; 95% CI: 0.71-0.91; P < 0.001), and Medicaid (OR = 0.85; 95% CI = 0.76-0.95; P = 0.005) patients were less likely to receive SSRF.

CONCLUSIONS

No differences in clinical outcomes were measured between adults aged 45-64 and ≥65 who underwent SSRF. Older age should not preclude patients from receiving SSRF. Further work is needed to improve underutilization in Black, Hispanic and Medicaid patients.

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%.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Comparative study of wound outcomes and surgical strategies: Internal fixation versus external stabilization in rib fracture patients with traumatic chest wounds

The clinical management of traumatic chest incisions accompanied by rib fractures presents the formidable challenge. The study was carried out to compare the outcomes of auscultatory triangle internal fixation (ATIF) and external fixation (EF) in such injuries. From June 2019 to June 2022, 105 patients with multiple rib fractures participated in the cohort study in which they were divided into two groups: 53 patients underwent ATIF and 52 patients underwent EF. The incidence of surgical site infection, wound healing time, incidence of wound dehiscence, number of dressing changes, pain as measured by the visual analogue scale (VAS), duration of hospitalization, period of return to work, pulmonary complications and functionality of the upper limbs as assessed by the Disability of Arm, Shoulder, and Hand (DASH) questionnaire were among the parameters evaluated. In comparison with EF, ATIF demonstrated the decreased incidence of wound dehiscence (1.9% vs. 9.6%) (p < 0.05), surgical site infection (3.8 vs. 11.5) and wound healing time (12.3 ± 2.1 vs. 18.5 ± 3.7 days) (p < 0.05). Furthermore, during their ATIF treatment, patients required fewer changes of dressing (3.5 ± 0.8 vs. 5.7 ± 1.2) and demonstrated enhanced pain management, reduced hospital stays and expedited return to work (p < 0.05). ATIF group demonstrated enhancements in both upper limb functionality and post-operative pulmonary function (p < 0.05). The utilization of ATIF as opposed to EF for the treatment of traumatic chest wounds accompanied by rib fractures yields superior outcomes in terms of wound healing, infection reduction and restoration of pulmonary and upper limb functionality.

Outcomes of Surgical Rib Plating: A Case Series

Rib fractures are a common result of blunt thoracic trauma. Complications of rib fractures include pneumothorax, hemothorax, respiratory failure, and death. The conservative management of rib fractures has been the mainstay of care with surgical rib fixation as a secondary management only performed in complicated flail segments. The purpose of this retrospective study is to describe the outcomes of six patients who underwent surgical rib fixation following a traumatic injury at a Level 1 trauma center. All care for these cases was performed at Desert Regional Medical Center in Palm Springs, CA. On average, patients stayed 12.3 total days in the hospital and 4.6 in the intensive care unit. Out of the six patients, only one required prolonged respiratory support eventually resulting in respiratory failure and death. This retrospective study on surgical rib fixation highlights the importance of early surgical intervention and the need for more general and trauma surgeons to be familiar with the procedure itself.

Investigating the link between frailty and outcomes in geriatric patients with isolated rib fractures

Background

Studies have shown an increased risk of morbidity in elderly patients suffering rib fractures from blunt trauma. The association between frailty and rib fractures on adverse outcomes is still ill-defined. In the current investigation, we sought to delineate the association between frailty, measured using the Orthopedic Frailty Score (OFS), and outcomes in geriatric patients with isolated rib fractures.

Methods

All geriatric (aged 65 years or older) patients registered in the 2013-2019 Trauma Quality Improvement database with a conservatively managed isolated rib fracture were considered for inclusion. An isolated rib fracture was defined as the presence of ≥1 rib fracture, a thorax Abbreviated Injury Scale (AIS) between 1 and 5, an AIS ≤1 in all other regions, as well as the absence of pneumothorax, hemothorax, or pulmonary contusion. Based on patients' OFS, patients were classified as non-frail (OFS 0), pre-frail (OFS 1), or frail (OFS ≥2). The prevalence ratio (PR) of composite complications, in-hospital mortality, failure-to-rescue (FTR), and intensive care unit (ICU) admission between the OFS groups was determined using Poisson regression models to adjust for potential confounding.

Results

A total of 65 375 patients met the study's inclusion criteria of whom 60% were non-frail, 29% were pre-frail, and 11% were frail. There was a stepwise increased risk of complications, in-hospital mortality, and FTR from non-frail to pre-frail and frail. Compared with non-frail patients, frail patients exhibited a 87% increased risk of in-hospital mortality [adjusted PR (95% CI): 1.87 (1.52-2.31), p<0.001], a 44% increased risk of complications [adjusted PR (95% CI): 1.44 (1.23-1.67), p<0.001], a doubling in the risk of FTR [adjusted PR (95% CI): 2.08 (1.45-2.98), p<0.001], and a 17% increased risk of ICU admission [adjusted PR (95% CI): 1.17 (1.11-1.23), p<0.001].

Conclusion

There is a strong association between frailty, measured using the OFS, and adverse outcomes in geriatric patients managed conservatively for rib fractures.

Trauma (Excluding Falls) in the Older Adult

Trauma in the older adult will increasingly become important to emergency physicians hoping to optimize their patient care. The geriatric patient population possesses higher rates of comorbidities that increase their risk for trauma and make their care more challenging. By considering the nuances that accompany the critical stabilization and injury-specific management of geriatric trauma patients, emergency physicians can decrease the prevalence of adverse outcomes.

Knowledge domain and emerging trends in multimorbidity and frailty research from 2003 to 2023: a scientometric study using citespace and VOSviewer

BACKGROUND

Multimorbidity and frailty represent emerging global health burdens that have garnered increased attention from researchers over the past two decades. We conducted a scientometric analysis of the scientific literature on the coexistence of multimorbidity and frailty to assess major research domains, trends, and inform future lines of research.

METHODS

We systematically retrieved scientific publications on multimorbidity and frailty from the Web of Science Core Collection, spanning from 2003 to 2023. Scientometric analysis was performed using CiteSpace and VOSviewer, enabling the visualization and evaluation of networks comprising co-citation references, co-occurring keywords, countries, institutions, authors, and journals.

RESULTS

A total of 584 eligible publications were included in the analysis. An exponential rise in research interest in multimorbidity and frailty was observed, with an average annual growth rate of 47.92% in publications between 2003 and 2022. Three major research trends were identified: standardized definition and measurement of multimorbidity and frailty, comprehensive geriatric assessment utilizing multimorbidity and frailty instruments for older adults, and the multifaceted associations between these two conditions. The United States of America, Johns Hopkins University, Fried LP, and the Journal of the American Geriatrics Society were identified as the most influential entities within this field, representing the leading country, institution, author, and journal, respectively.

CONCLUSIONS

Scientometric analysis provides invaluable insights to clinicians and researchers involved in multimorbidity and frailty research by identifying intellectual bases and research trends. While the instruments and assessments of multimorbidity and frailty with scientific validity and reliability are of undeniable importance, further investigations are also warranted to unravel the underlying biological mechanisms of interactions between multimorbidity and frailty, explore the mental health aspects among older individuals with multimorbidity and frailty, and refine strategies to reduce prescriptions in this specific population.

Evaluation and Treatment of Acute Trauma Pain in Older Adults

In the context of an ageing population, the demographic sands of trauma are shifting. Increasingly, trauma units are serving older adults who have sustained injuries in low-energy falls from a standing height. Older age is commonly associated with changes in physiology, as well as an increased prevalence of frailty and multimorbidity, including cardiac, renal and liver disease. These factors can complicate the safe and effective administration of analgesia in the older trauma patient. Trauma services therefore need to adapt to meet this demographic shift and ensure that trauma clinicians are sufficiently skilled in treating pain in complex older people. This article is dedicated to the management of acute trauma pain in older adults. It aims to highlight the notable clinical challenges of managing older trauma patients compared with their younger counterparts. It offers an overview of the evidence and practical opinion on the merits and drawbacks of commonly used analgesics, as well as more novel and emerging analgesic adjuncts. A search of Medline (Ovid, from inception to 7 November 2022) was conducted by a medical librarian to identify relevant articles using keyword and subject heading terms for trauma, pain, older adults and analgesics. Results were limited to articles published in the last 10 years and English language. Relevant articles' references were hand-screened to identify other relevant articles. There is paucity of dedicated high-quality evidence to guide management of trauma-related pain in older adults. Ageing-related changes in physiology, the accumulation of multimorbidity, frailty and the risk of inducing delirium secondary to analgesic medication present a suite of challenges in the older trauma patient. An important nuance of treating pain in older trauma patients is the challenge of balancing iatrogenic adverse effects of analgesia against the harms of undertreated pain, the complications and consequences of which include immobility, pneumonia, sarcopenia, pressure ulcers, long-term functional decline, increased long-term care needs and mortality. In this article, the role of non-opioid agents including short-course non-steroidal anti-inflammatory drugs (NSAIDs) is discussed. Opioid selection and dosing are reviewed for older adults suffering from acute trauma pain in the context of kidney and liver disease. The evidence base and limitations of other adjuncts such as topical and intravenous lidocaine, ketamine and regional anaesthesia in acute geriatric trauma are discussed.

Clinical characteristics of patients with the hardware failure after surgical stabilization of rib fractures in Korea: a case series

Purpose

Surgical stabilization of rib fractures (SSRF) is widely used in patients with flail chests, and several studies have reported the efficacy of SSRF even in multiple rib fractures. However, few reports have discussed the hardware failure (HF) of implanted plates. We aimed to evaluate the clinical characteristics of patients with HF after SSRF and further investigate the related factors.

Methods

We retrospectively reviewed the electronic medical records of patients who underwent SSRF for multiple rib fractures at a level I trauma center in Korea between January 2014 and January 2021. We defined HF as the unintentional loosening of screws, dislocation, or breakage of the implanted plates. The baseline characteristics, surgical outcomes, and types of HF were assessed.

Results

During the study period, 728 patients underwent SSRF, of whom 80 (10.9%) were diagnosed with HF. The mean age of HF patients was 56.5±13.6 years, and 66 (82.5%) were men. There were 59 cases (73.8%) of screw loosening, 21 (26.3%) of plate breakage, 17 (21.3%) of screw migration, and seven (8.8%) of plate dislocation. Nine patients (11.3%) experienced wound infection, and 35 patients (43.8%) experienced chronic pain. A total of 21 patients (26.3%) underwent reoperation for plate removal. The patients in the reoperation group were significantly younger, had fewer fractures and plates, underwent costal fixation, and had a longer follow-up. There were no significant differences in subjective chest symptoms or lung capacity.

Conclusions

HF after SSRF occurred in 10.9% of the cases, and screw loosening was the most common. Further longitudinal studies are needed to identify risk factors for SSRF failure.

Erector Spinae Plane Block as an Analgesic Intervention in Acute Rib Fractures: A Scoping Review

Introduction

Rib fractures are a common sequelae of chest trauma and are associated with significant morbidity. The erector spinae nerve block (ESB) has been proposed as an alternative first-line regional technique for rib fractures due to ease of administration and minimal complication profile. We aimed to investigate the current literature surrounding this topic with a focus on pain and respiratory outcomes.

Methods

A comprehensive literature search was performed on the Medline, Embase, Web of Science, Scopus, and Cochrane databases. Keywords of "erector spinae block" and "rib fractures" were used to form the search strategy. Papers published in English investigating ESB as an analgesic intervention for acute rib fracture were included. Exclusion criteria were operative rib fixation, or where the indication for ESB was not rib fracture.

Results

There were 37 studies which met the inclusion criteria for this scoping review. Of these, 31 studies reported on pain outcomes and demonstrated a 40% decrease in pain scores post administration within the first 24 hours. Respiratory parameters were reported in 8 studies where an increase in incentive spirometry was demonstrated. Respiratory complication was not consistently reported. ESB was associated with minimal complications; only 5 cases of haematoma and infection were (incidence 0.6%) reported, none of which required further intervention.

Discussion

Current literature surrounding ESB in rib fracture management provides a positive qualitative evaluation of efficacy and safety. Improvements in pain and respiratory parameters were almost universal. The notable outcome from this review was the improved safety profile of ESB. The ESB was not associated with complications requiring intervention even in the setting of anticoagulation and coagulopathy. There still remains a paucity of large cohort, prospective data. Moreover, no current studies reflect an improvement in respiratory complication rates compared to current techniques. Taken together, these areas should be the focus of any future research.

Is severe traumatic brain injury no longer a contraindication for surgical stabilization of rib fractures in patients with multiple rib fractures? A propensity-matched analysis

BACKGROUND

Traumatic brain injury (TBI) is often considered a contraindication to surgical stabilization of rib fractures (SSRF). In this study, we hypothesized that, compared with nonoperative management, SSRF is associated with improved outcomes in TBI patients.

METHODS

Using the American College of Surgeons Trauma Quality Improvement Program 2016-2019, we performed a retrospective analysis of patients with concurrent TBI and multiple rib fractures. Following propensity score matching, we compared patients who underwent SSRF with those who were managed nonoperatively. Our primary outcome was mortality. Secondary outcomes included ventilator-associated pneumonia, hospital and intensive care unit (ICU) length of stay (LOS), ventilator days, tracheostomy rate, and hospital discharge disposition. In a subgroup analysis, we stratified patients into mild and moderate TBI (GCS score >8) and severe TBI (GCS score ≤8).

RESULTS

Of 36,088 patients included in this study, 879 (2.4%) underwent SSRF. After propensity-score matching, compared with nonoperative management, SSRF was associated with decreased mortality (5.4% vs. 14.5%, p < 0.001), increased hospital LOS (15 days vs. 9 days, p < 0.001), increased ICU LOS (12 days vs. 8 days, p < 0.001), and increased ventilator days (7 days vs. 4 days, p < 0.001). In the subgroup analyses, in mild and moderate TBI, SSRF was associated with decreased in-hospital mortality (5.0% vs. 9.9%, p = 0.006), increased hospital LOS (13 days vs. 9 days, p < 0.001), ICU LOS (10 days vs. 7 days, p < 0.001), and ventilator days (5 days vs. 2 days, p < 0.001). In patients with severe TBI, SSRF was associated with decreased mortality (6.2% vs. 18%, p < 0.001), increased hospital LOS (20 days vs. 14 days, p = 0.001), and increased ICU LOS (16 days vs. 13 days, p = 0.004).

CONCLUSION

In patients with TBI and multiple rib fractures, SSRF is associated with a significant decrease in in-hospital mortality and with longer hospital and ICU LOSs. These findings suggest that SSRF should be considered in patients with TBI and multiple rib fractures.

Evaluation of injury threshold from the number of rib fracture for predicting pulmonary injuries in blunt chest trauma

Background

Blunt chest trauma is a common presentation in emergency departments. The relationship between bone fractures and organ injuries has not been studied in detail. The purpose of this study was to examine the degree of external force represented by the number of rib fractures that causes lung injury in blunt chest trauma.

Patients and methods

This study was performed retrospectively using trauma patients who received medical examinations in a single university hospital emergency center between April 2015 and March 2020. We examined the association between the number of rib fractures and pulmonary damage using multivariable regression analysis and considered the relationship between rib fracture location and each type of lung injury.

Results

A total of 317 patients were included. The mean age was 63.1 years, 65.0% were male, and traffic accidents were the most common mechanism of injury (55.8%). The number of mean rib fractures was 4.0, and the mean Injury Severity Score was 11.3. The number of rib fractures was associated with an increased risk of pulmonary injuries: pulmonary contusion (odds ratio [OR] 1.30, 95% confidence interval [CI] 1.14-1.48, p < 0.05); hemothorax (OR 1.22, 95% CI 1.08-1.38, p < 0.05); pneumothorax (OR 1.15, 95% CI 1.02-1.30, p < 0.05); and hemopneumothorax (OR 1.14, 95% CI 1.01-1.28, p < 0.05). In addition, bilateral rib fractures were associated with fractures of the superior ribs more often and more severely, but were not associated with the occurrence of each type of lung injury.

Conclusion

The number of rib fractures was associated with an increased risk of pulmonary injuries. In addition, the type of pulmonary injury could be predicted from the number of rib fractures in blunt chest trauma.

Rib Fracture Map in High-Energy Injuries

OBJECTIVES

To use a novel rib unfurling technology to investigate the locations of multiple rib fractures occurring from high-energy trauma to discern if there are reproducible rib fracture patterns.

METHODS

Patients between the ages of 18 and 48 years presenting to a Level 1 academic trauma center with ≥2 rib fractures after a high-energy mechanism of injury between 2017 and 2019 were identified. Curved planar reformatting of CT scans was used to create two-dimensional unfurled rib images by flattening out the view of the ribs from a CT scan. Rib fractures were placed on a template map using a standardized measurement method, and subsequent frequency and heat maps were created.

RESULTS

Among 100 consecutive patients, 534 fractures on 454 ribs were identified. The most common high-energy mechanism of injury was motor vehicle accidents (41%). Flail chest occurred in 8% of patients. The mean number of ribs fractured per patient was 4.54 ± 3.14 and included a mean of 5.34 ± 4.38 total fractures. Among all fractures, 50.9% were located on ribs 4 through 7. The most common fracture location was located in the lateral or anterolateral zone of the rib cage.

CONCLUSIONS

Patients with multiple rib fractures from high-energy trauma have rib fractures with locations of common occurrence. An understanding of location and frequency of rib fractures can help inform surgical approaches, prognosis, indications, classifications, and implant design in the management of a complex population of patients with chest wall injury after trauma.

Characteristics of rib fracture patients who require chest computed tomography in the emergency department

BACKGROUND

The disadvantages and complications of computed tomography (CT) can be minimized if CT is performed in rib fracture patients with high probability of intra-thoracic and intra-abdominal injuries and CT is omitted in rib fracture patients with low probability of intra-thoracic and intra-abdominal injuries. This study aimed to evaluate the factors that can identify patients with rib fractures with intra-thoracic and intra-abdominal injuries in the emergency department among patients with rib fracture.

METHODS

This retrospective observational study included adult patients (age ≥ 18 years) diagnosed with rib fracture on chest radiography prior to chest CT due to blunt chest trauma in the emergency department who underwent chest CT from January 2016 to February 2021. The primary outcomes were intra-thoracic and intra-abdominal injuries that could be identified on a chest CT. Multivariate logistic regression analysis was performed.

RESULTS

Among the characteristics of rib fractures, the number of rib fractures was greater (5.0 [3.0-7.0] vs. 2.0 [1.0-3.0], p < 0.001), bilateral rib fractures were frequent (56 [20.1%] vs. 12 [9.8%], p = 0.018), and lateral and posterior rib fracture was more frequent (lateral rib fracture: 160 [57.3%] vs. 25 [20.5%], p < 0.001; posterior rib fracture: 129 [46.2%] vs. 21 [17.2%], p < 0.001), and displacement was more frequent (99 [35.5%] vs. 6 [6.6%], p < 0.001) in the group with intra-thoracic and intra-abdominal injuries than in the group with no injury. The number of rib fractures (adjusted odds ratio [aOR], 1.44; 95% confidence interval [CI], 1.16-1.78; p = 0.001), lateral rib fracture (aOR, 2.80; 95% CI, 1.32-5.95; p = 0.008), and posterior rib fracture (aOR, 3.18; 95% CI, 1.45-6.94; p = 0.004) were independently associated with intra-thoracic and intra-abdominal injuries. The optimal cut-off for the number of rib fractures on the outcome was three. The number of rib fractures ≥ 3 (aOR, 3.01; 95% CI, 1.35-6.71; p = 0.007) was independently associated with intra-thoracic and intra-abdominal injuries.

CONCLUSION

In patients with rib fractures due to blunt trauma, those with lateral or posterior rib fractures, those with ≥ 3 rib fractures, and those requiring O₂ supplementation require chest CT to identify significant intra-thoracic and intra-abdominal injuries in the emergency department.

Evaluation of surgical outcomes in elderly patients with rib fractures: A single-centre propensity score matching study

Background

Rib fractures are the most common injuries in chest trauma. Compared with younger patients, elderly patients with rib fracture have a higher incidence of complications and mortality. A retrospective study was conducted to investigate the effect of internal fixation compared with conservative treatment on the outcome of rib fracture in elderly patients.

Material and methods

We used a 1:1 propensity score matching method to perform a retrospective analysis of 703 elderly patients with rib fractures treated in the Thoracic Surgery Department of Beijing Jishuitan Hospital between 2013 and 2020. After matching, the length of hospital stay, death, symptom relief and rib fracture healing were compared between the surgery and the control group.

Results

The study included 121 patients receiving SSRF in the surgery group and 121 patients receiving conservative treatment in the control group. The length of hospital stay in the surgery group was significantly longer than that in the conservative group (11.39d vs. 9.48d, p = 0.000). After 9 months of follow-up, the fracture healing rate in the surgery group was significantly higher than that in the control group (96.67% vs. 88.89%, p = 0.020). The fracture healing time (p = 0.000), improvement in pain score (p = 0.000) and duration of pain medication use (p = 0.000) were also significantly better in the surgery group than in the control group.

Conclusion

Compared with conservative treatment, surgical treatment can prolong hospital stay to some extent. However, it has the advantages of more rapid healing and lessened pain. For rib fractures in elderly individuals, surgical treatment is a safe and effective option under strict surgical indications and is recommended.

The revised cardiac risk index is associated with morbidity and mortality independent of injury severity in elderly patients with rib fractures

BACKGROUND

Risk factors for mortality and in-hospital morbidity among geriatric patients with traumatic rib fractures remain unclear. Such patients are often frail and demonstrate a high comorbidity burden. Moreover, outcomes anticipated by current rubrics may reflect the influence of multisystem injury or surgery, and thus not apply to isolated injuries in geriatric patients. We hypothesized that the Revised Cardiac Risk Index (RCRI) may assist in risk-stratifying geriatric patients following rib fracture.

METHODS

All geriatric patients (age ≥65 years) with a conservatively managed rib fracture owing to an isolated thoracic injury (thorax AIS ≥1), in the 2013-2019 TQIP database were assessed including demographics and outcomes. The association between the RCRI and in-hospital morbidity as well as mortality was analyzed using Poisson regression models while adjusting for potential confounders.

RESULTS

96,750 geriatric patients sustained rib fractures. Compared to those with RCRI 0, patients with an RCRI score of 1 had a 16% increased risk of in-hospital mortality [adjusted incidence rate ratio (adj-IRR), 95% confidence interval (CI): 1.16 (1.02-1.32), p=0.020]. An RCRI score of 2 [adj-IRR (95% CI): 1.72 (1.44-2.06), p<0.001] or ≥3 [adj-IRR (95% CI): 3.07 (2.31-4.09), p<0.001] was associated with an even greater mortality risk. Those with an increased RCRI also exhibited a higher incidence of myocardial infarction, cardiac arrest, stroke, and acute respiratory distress syndrome.

CONCLUSIONS

Geriatric patients with rib fractures and an RCRI ≥1 represent a vulnerable and high-risk group. This index may inform the decision to admit for inpatient care and can also guide patient and family counseling as well as computer-based decision-support.

Regional anesthesia and analgesia for trauma: an updated review

PURPOSE OF REVIEW

This narrative review is an updated summary of the value of regional anesthesia and analgesia for trauma and the special considerations when optimizing pain management and utilizing regional analgesia for acute traumatic pain.

RECENT FINDINGS

In the setting of the opioid epidemic, the need for multimodal analgesia in trauma is imperative. It has been proposed that inadequately treated acute pain predisposes a patient to increased risk of developing chronic pain and continued opioid use. Enhanced Regional Anesthesia techniques along with multimodal pain therapies is thought to reduce the stress response and improve patient's short- and long-term outcomes.

SUMMARY

Our ability to save life and limb has improved, but our ability to manage acute traumatic pain continues to lag. Understanding trauma-specific concerns and tailoring the analgesia to a patient's specific injuries can increase a patient's immediate comfort and long-term outcome as well.

The Surgical Timing and Complications of Rib Fixation for Rib Fractures in Geriatric Patients

Rib fractures (RF) are a common injury that cause significant morbidity and mortality, especially in geriatric patients. RF fixation could shorten hospital stay and improve survival. The aim of this retrospective study was to evaluate the clinical impact and proper surgical timing of RF fixation in geriatric patients. We reviewed all the medical data of patients older than 16 years old with RF from the trauma registry database between January 2017 and December 2019 in Chang Gung Memorial Hospital. A total of 1078 patients with RF were enrolled, and 87 patients received RF fixation. The geriatric patients had a higher chest abbreviated injury scale than the non-geriatric group (p = 0.037). Univariate analysis showed that the RF fixation complication rates were significantly related to the injury severity scores (Odds ratio 1.10, 95% CI 1.03–1.20, p = 0.009) but not associated with age (OR 0.99, 95% CI 0.25–3.33, p = 0.988) or the surgical timing (OR 2.94, 95% CI 0.77–12.68, p = 0.122). Multivariate analysis proved that only bilateral RF was an independent risk factor of complications (OR 6.60, 95% CI 1.38–35.54, p = 0.02). RF fixation can be postponed for geriatric patients after they are stabilized and other lethal traumatic injuries are managed as a priority.

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.

Cryoneurolysis of Intercostal Nerve for Rib Trauma and Intercostal Neuralgia in the Emergency Department: A Multidisciplinary Approach

BACKGROUND

Management of pain from traumatic rib injury is very challenging. Both acute and chronic pain caused by rib injury can cause significant morbidity (pain-induced hypoventilation, pneumonia, respiratory failure) and functional hindrance. Traditional pain management strategies in the emergency department (ED) that target acute traumatic rib pain are limited by the side effects of medications or the temporary half-life of anesthetics used for a nerve block. Both treatment modalities fall short of addressing subsequent chronic sequelae.

CASE REPORT

We present the first-time use of cryoneurolysis on an ED patient for the treatment of 10/10 severe traumatic intercostal neuralgia that resulted in the patient being discharged home pain free. The patient initially underwent a multilevel left-sided T5-T7 intercostal nerve block, followed by ultrasound-guided percutaneous cryoneurolysis of those intercostal nerves using two cycles of 2 min of cooling to a temperature of -70°C (nitrous oxide), with 30 s of thawing in between. The patient experienced 100% pain relief immediately post procedure that was sustained. He remained completely symptom free more than 6 months after the bedside procedure and returned to sports without restrictions. Why Should an Emergency Physician Be Aware of This? This case highlights the benefits of cross-departmental collaboration between the ED, Anesthesia, and Pain Management. We hope this model of multidisciplinary pain modulation can be replicated for other patients with similar pain and can herald a new paradigm of pain management in the ED.

Effect of an intervention for patients 65 years and older with blunt chest injury: Patient and health service outcomes

INTRODUCTION

Blunt chest injury in older adults, aged 65 years and older, leads to significant morbidity and mortality. The aim of this study was to evaluate the effect of a multidisciplinary chest injury care bundle (ChIP) on patient and health service outcomes in older adults with blunt chest injury.

METHODS

ChIP comprised multidimensional implementation guidance in three key pillars of care for blunt chest injury: respiratory support, analgesia, and complication prevention. Implementation was guided using the Behaviour Change Wheel. This proof-of-concept controlled pre- and post-test study with two intervention and two control sites in Australia was conducted from July 2015 to June 2019. The primary outcomes were non-invasive ventilation (NIV) use, unplanned Intensive Care Unit (ICU) admissions, and in-hospital mortality. Secondary outcomes were health service and costing outcomes.

RESULTS

There were 1122 patients included in the analysis, with 673 at intervention sites (331 pre-test and 342 post-test) and 449 at control sites (256 pre-test and 193 post-test). ChIP was associated with unplanned ICU admissions and in NIV use with a reduction of the odds in the post vs the pre periods in the intervention sites when compared to the controls (ratio of OR=0.13, 95%CI=0.03-0.55) and (ratio of OR=0.14, 95%CI=0.02-0.98) respectively. There was no significant change in mortality. Implementing ChIP was also associated with health service team reviews with an increased odds in the post vs pre periods in the intervention sites in comparison to the controls for surgical review (ratio of OR =6.93, 95%CI=4.70-10.28), ICU doctor (ratio of OR =5.06, 95%CI=2.26-9.25), ICU liaison (ratio of OR =14.14, 95%CI=3.15-63.31), and pain (ratio of OR =5.59, 95%CI=3.25-9.29). ChIP was also related to incentive spirometry (ratio of OR=6.35, 95%CI= 3.15-12.82) and overall costs (ratio of mean ratio=1.34, 95%CI=1.09-1.66) with a higher ratio for intervention sites.

CONCLUSION

Implementation of ChIP using the Behaviour Change Wheel was associated with reduced unplanned ICU admissions and NIV use and improved health care delivery.

Implementation of a chest injury pathway in the emergency department

Rib fractures represent a substantial health burden. Chest injuries contribute to 25% of deaths after trauma and survivors can experience long-standing consequences, such as reduced functional capabilities and loss of employment. Over recent years, there has been an increase in the awareness of the importance of early identification, aggressive pain management and adequate safety netting for patients with chest injuries. Substandard management leads to increased rates of morbidity and mortality. The development of protocols in the emergency department (ED) for management of patients with chest wall injuries has demonstrated reduction of complication rates.

Our aim was to develop an evidence-based, multidisciplinary chest injury pathway for the management of patients presenting with rib injury to our ED.

Prior to implementation of the pathway in our department, only 39% of patients were documented as having received analgesia and only 7% of discharged patients had documented written verbal advice. There was no standardised method to perform regional anaesthetic blocks. Using quality improvement methods, we standardised imaging modality, risk stratification with a scoring system, analgesia with emphasis on regional anaesthesia blocks and disposition with information leaflets for those discharged.

Implementation of the pathway increased rates of documented analgesia received from 39% to 70%. The number of regional anaesthetic blocks performed went from 0% to 60% and the number of patients receiving discharge advice went from 7% to 70%. Compliance of doctors and nurses with the pathway was 63%.

Our previous audits showed substandard management of patients with chest injuries in our department. Through this quality improvement project, we were able to improve the quality of care provided to patients attending with rib fractures by increasing rate of analgesia received, regional blocks performed and discharge advice given.

A Model of Care to Improve Survival of Older Trauma Patients: Geriatrics Co-Management

BACKGROUND

Trauma patients older than 80 years of age have higher mortality rates compared to younger peers. No studies have investigated the effectiveness of geriatrics co-management on mortality in general trauma.

METHODS

Retrospective cohort study from 2015-2016 comparing overall and inpatient mortality in a geriatrics trauma co-management (GTC) program versus usual care (UC). Demographic and outcome measures were obtained from the trauma registry at an 11-bed trauma critical care unit within a 719-bed Level 1 Trauma Center. 1,572 patients, 80 years and older, with an admitting trauma diagnosis were evaluated. Primary outcome was in-hospital mortality and overall mortality (defined as inpatient death or discharge to hospice). Secondary outcomes included hospital length of stay (LOS), Intensive Care Unit (ICU) LOS, discharge location, and medical complications.

RESULTS

346 patients (22%) were placed in the GTC program. Overall mortality was lower in the GTC (4.9%) when compared with UC (11.9%), representing a 57% reduction (95% OR CI 0.24-0.75, p-value = 0.0028). There was a 7.42% hospital mortality rate in the UC group compared to 2.6% in the GTC group (95% CI 0.21-0.92, p-value = 0.0285) representing a 56% decrease in in-hospital mortality. GTC patients had a longer mean LOS (6.4 days versus 5.3 days, p-value <0.0001). More GTC patients were sent to inpatient rehabilitation facilities or skilled nursing facilities (80% versus 60%, p-value <0.0001).

CONCLUSIONS

Geriatrics trauma co-management of trauma patients above the age of 80 may reduce mortality and deserves formal study.

Finite element analysis of different fixation methods of screws on absorbable plate for rib fractures

Multiple rib fractures caused by trauma are common injuries and the internal fixation methods of these injuries have been paid more and more attention by surgeons. Absorbable plates and screws are the effective way to treat rib fractures, but there are no reports on which type of screw fixation method is most effective. In this study, finite element analysis was used to study the effects of five different types of screw fixation methods on anterior rib, lateral rib and posterior rib. The finite element model of the ribs was reconstructed from CT images, and the internal pressure (40 kPa) and intercostal force (30 N) on the surfaces of the ribs were simulated accordingly. An intercostal force of 30 N was applied to the upper and lower surfaces of the ribs to simulate the effect of intercostal muscle force. The pressure of 40 kPa was applied to the inner surface of the ribs, and the normal direction was applied to the inner surface of the ribs. The positive direction was considered inspiratory pressure, and the negative direction was considered expiratory pressure. The results indicate the optimal type of screw fixation on the absorbable plate for rib fractures, and provide a basis and reference for clinical application.

Management of Advanced Aged Patients with Rib Fractures: Current Evidence and Review of the Literature

Elderly patients (age > 60 years old) represent the majority of the victims of major trauma, and rib fractures account for 10% of all trauma admissions. Due to the growing interest in surgical rib fixation and the lack of evidence on the best treatment available, we aimed to compare the conservative and operative approaches among the elderly population with multiple rib fractures. The systematic review identified seven eligible studies from over 321 papers collected through the database screening process. The mortality rate, considered the primary outcome, was higher in the conservative-treated group than the operatively-treated patients (8.3% vs. 3%). Considering the secondary outcomes investigated, the overall intensive care unit stay and in-hospital length of stay were longer in the operatively-treated patients (6.3 and 13.3 vs. 4.7 and 7.7, respectively). Conversely, the operative treatment showed favorable results regarding the pneumonia complication rate (5.8% vs. 9.6%), while the duration of mechanical ventilation was similar for both treatments. Surgical stabilization of rib fractures in the elderly population appears to be associated with a survival advantage and avoiding pulmonary complications. However, the individual contribution of operative and conservative treatment in reducing morbidity and mortality in the elderly with multiple rib fractures remains unclear.

Physician-Led Thoracic Trauma Management in a Specialist Emergency Care Centre

INTRODUCTION

Falls cause 75% of trauma in patients above 65 years of age, and thoracic trauma is the second commonest injury; rib fractures are the most common thoracic injury. These patients have up to 12% mortality, with 31% developing pneumonias. There is wide variation in care. Northumbria Healthcare has a team of respiratory consultants, physiotherapists, specialist nurses and anesthetists for thoracic-trauma management on a respiratory support unit.

METHODS

With Caldicott approval, basic demographics and clinical outcomes of patients admitted with thoracic trauma between 20 August-21 April were analyzed. A descriptive statistical methodology was applied.

RESULTS

A total of 119 patients were identified with a mean age of 71.1 years (range 23-97). Of the 119 patients, 53 were male, 66 females. The main mechanism of injury was falls from standing (65) and falls down stairs/bed or in the bath (18). Length of stay was 7.3 days (range 1-54). In total, 85 patients had more than one co-morbidity, 26 had a full trauma assessment and 75 had pan CTs. The mean number of rib fractures was 3.6 and 31 (26%) patients had a pneumothorax and/or haemothorax. A total of 18 chest drains were inserted (all small bore) and one needle aspiration was performed. No cardiothoracic input was required. Isolated chest trauma was present only in 45 patients. All patients had a pain team review, 22 erector spinae catheters were inserted with 2 paravertebral blocks. Overall, 82 patients did not require oxygen, 1 required CPAP and 1 HFNC. 7 needed intensive care transfer. Furthermore, 20 (17%) developed pneumonias and 16 (14%) deaths occurred within 30 days-all were in those with falls from standing. There was no correlation between number of fractured ribs, length of stay and mortality.

CONCLUSIONS

High level care for thoracic trauma can be performed by a physician led team. Overall, 42% pneumothoraces/haemothoraces were observed. Further large scale randomised trials are warranted for definitive outcomes.

Are rib fractures stable? An analysis of progressive rib fracture offset in the acute trauma setting

BACKGROUND

Rib fractures serve as both a marker of injury severity and a guide for clinical decision making for trauma patients. Although recent studies have suggested that rib fractures are dynamic, the degree of progressive offset remains unknown. The purpose of this study was to further characterize the change that takes place in the acute trauma setting.

METHODS

A 4-year (2016-2019) retrospective assessment of adult trauma patients with rib fracture(s) admitted to a level I trauma center was performed. Initial and follow-up computed tomography scans were analyzed to determine the magnitude of offset. Relevant clinical course variables were examined, and location of chest wall instability was examined using the difference of interquartile range of median change. Statistical Product and Services Solutions (Version 25, IBM Corp. Armonk, NY) was then used to generate a neural network-multilayer perceptron that highlighted independent variable importance.

RESULTS

Fifty-three patients met the inclusion criteria for severe injury. Clinical course variables that either trended or significantly predicted the occurrence of progressive offset were Abbreviated Injury Scale Thoracic Scores (3.1 ± 0.4 no progression vs. 3.4 ± 0.6 yes progression; p = 0.121), flail segment (14% no progression vs. 43% yes progression; p = 0.053), and number of ribs fractured (4 [2-8] no progression vs. 7 [5-9] yes progression; p = 0.023). The location of progressive offset largely corresponded to the posterolateral region as demonstrated by the differences of interquartile range of median change. The neural network demonstrated that ribs 4 to 6 (normalized importance [NI], 100%), the posterolateral region (NI, 87.9%), and multiple fractures per rib (NI, 66.6%) were valuable in predicting whether progressive offset occurred (receiver operating characteristic curve - area under the curve = 0.869).

CONCLUSION

Rib fractures are not stable, particularly for those patients with multiple fractures in the mid-to-upper ribs localized to the posterolateral region. These findings may identify both trauma patients with worse outcomes and help develop better management strategies for rib fractures.

Age-Related Hearing Loss With Tinnitus and Physical Frailty Influence the Overall and Domain-Specific Quality of Life of Chinese Community-Dwelling Older Adults

Objective: To investigate the impact of the severity of age-related hearing loss (ARHL) and tinnitus, presence of ARHL and/or tinnitus, and physical frailty on the health-related quality of life (HRQoL) and domain-specific HRQoL in Chinese community-dwelling older adults. Design: This was a cross-sectional study of a community-based cohort. Participants: We evaluated Chinese older adults (n = 429, 183 men and 246 women) aged ≥ 58years. Measurements: The severity of HL and tinnitus were measured using pure-tone audiometry and the Tinnitus Handicap Inventory (THI), respectively. Physical frailty was measured using the five-item Fried scale. HRQoL was assessed using the Assessment of Quality of Life-8-Dimension (AQoL-8D) multi-attribute utility instrument (35 HRQoL items and eight domain-specific HRQoL subcategories). Low HRQoL (HRQoL score or subscores in the highest quintile) was used as a dependent variable in logistic regression analyses adjusted for demographic (Model 1) and health-related (Model 2) and psychosocial (Model 3) confounders. Results: Age-related hearing loss severity was an independent determinant of senses in the physical dimension of HRQoL after adjusting for all covariates. Tinnitus severity was significantly associated with HRQoL and with independent living, senses, and pain in the physical dimension after adjusting for demographic and health-related covariates and was still associated with independent living and senses after adjusting for all covariates. The presence of ARHL and/or tinnitus was significantly associated with independent living and senses in the physical dimension after adjusting for all the covariates. Physical frailty was an independent determinant of HRQoL, independent living, and pain in the physical dimension and with mental health, happiness, and coping in the psychosocial dimension after adjusting for demographic and health-related covariates. The association with HRQoL, independent living, and pain in the physical dimension, and with happiness and coping in the psychosocial dimension remained significant after adjusting for the covariates. Depressive symptoms, social dysfunction, and a number of comorbidities were critical determinants of psychosocial HRQoL. Conclusion: Physical frailty has a stronger and more profound effect on HRQoL, particularly on independent living and pain in the physical dimension and on happiness and coping in the psychosocial dimension. Domain-specific HRQoL should be considered in the management of patients with ARHL with tinnitus and physical frailty. Clinical Trial Registration: www.ClinicalTrials.gov, identifier: NCT2017K020.

A survey of current practice in UK emergency department management of patients with blunt chest wall trauma not requiring admission to hospital

INTRODUCTION

There is no universal agreement or supporting evidence for the content or format of a standardised guidance document for patients with blunt chest wall trauma. The aim of this study is to investigate current UK Emergency Medicine practice of the management of patients with blunt chest wall trauma, who do not require admission to hospital.

METHODS

This was a cross-sectional survey study, with mixed quantitative / qualitative analysis methods. A convenience sample of all professions working in the Emergency Departments / Urgent Care Centres in the UK was used. A combination of closed and open-ended questions were included, covering demographics and current practice in the respondent's main place of work. Themes explored included management strategies for safe discharge home, risk prediction and variables considered relevant for inclusion in patient guidance.

RESULTS

A total of 113 clinicians responded from all UK trauma networks, including all devolved nations. A total of 20 different risk prediction tools / pathways were reported to be used when assessing whether a patient is safe for discharge home, with over 35 different variables listed by respondents as being important to highlight to patients. Qualitative analysis revealed that a small number of respondents believe patients can be better managed through the improvement of the following; identification of the high-risk patient, initial assessment and current management strategies used in the ED / UCC.

DISCUSSION

The wide variation in practice highlighted in this study may be due in part to a lack of national consensus guidelines on how to manage this complex patient group. Further research is needed into whether structured national guidelines for the assessment and management of such patients could potentially lead to an overall improvement in outcomes. Such guidelines should be developed by not only expert clinicians and researchers, but also and more importantly by those service-users who have lived experience of blunt chest wall trauma.

What is the optimal timing to perform surgical stabilization of rib fractures?

The practice of surgical stabilization of rib fractures (SSRF) for severe chest wall injury has exponentially increased over the last decade due to improved outcomes as compared to nonoperative management. However, regarding in-hospital outcomes, the ideal time from injury to SSRF remains a matter of debate. This review aims to evaluate and summarize currently available literature related to timing of SSRF. Nine studies on the effect of time to SSRF were identified. All were retrospective comparative studies with no detailed information on why patients underwent early or later SSRF. Patients underwent SSRF most often for a flail chest or ≥3 displaced rib fractures. Early SSRF (≤48-72 hours after admission) was associated with shorter hospital and intensive care unit length of stay (HLOS and ICU-LOS, respectively), duration of mechanical ventilation (DMV), and lower rates of pneumonia, and tracheostomy as well as lower hospitalization costs. No difference between early or late SSRF was demonstrated for mortality rate. As compared to nonoperative management, late SSRF (>3 days after admission), was associated with similar or worse in-hospital outcomes. The optimal time to perform SSRF in patients with severe chest wall injury is early (≤48-72 hours after admission) and associated with improved in-hospital outcomes as compared to either late salvage or nonoperative management. These data must however be cautiously interpreted due the retrospective nature of the studies and potential selection and attrition bias. Future research should focus on both factors and pathways that allow patients to undergo early SSRF.

Use of regional analgesia and risk of delirium in older adults with multiple rib fractures: An Eastern Association for the Surgery of Trauma multicenter study

BACKGROUND

Single-center data demonstrates that regional analgesia (RA) techniques are associated with reduced risk of delirium in older patients with multiple rib fractures. We hypothesized that a similar effect between RA and delirium would be identified in a larger cohort of patients from multiple level I trauma centers.

METHODS

Retrospective data from seven level I trauma centers were collected for intensive care unit (ICU) patients 65 years or older with ≥3 rib fractures from January 2012 to December 2016. Those with a head and/or spine injury Abbreviated Injury Scale (AIS) score of ≥ 3 or a history of dementia were excluded. Delirium was defined as one positive Confusion Assessment Method for the Intensive Care Unit score in the first 7 days of ICU care. Poisson regression with robust standard errors was used to determine the association of RA (thoracic epidural or paravertebral catheter) with delirium incidence.

RESULTS

Data of 574 patients with a median age of 75 years (interquartile range [IQR], 69-83), Injury Severity Score of 14 (IQR, 11-18), and ICU length of stay of 3 days (IQR, 2-6 days) were analyzed. Among the patients, 38.9% were women, 15.3% were non-White, and 31.4% required a chest tube. Regional analgesia was used in 19.3% patients. Patient characteristics did not differ by RA use; however, patients with RA had more severe chest injury (chest AIS, flail segment, hemopneumothorax, thoracostomy tube). In univariate analysis, there was no difference in the likelihood of delirium between the RA and no RA groups (18.9% vs. 23.8% p = 0.28). After adjusting for age, sex, Injury Severity Score, maximum chest AIS, thoracostomy tube, ICU length of stay, and trauma center, RA was associated with reduced risk of delirium (incident rate ratio [IRR], 0.65; 95% confidence interval [CI], 0.44-0.94) but not with in-hospital mortality (IRR, 0.42; 95% CI, 0.14-1.26) or respiratory complications (IRR, 0.70; 95% CI, 0.42-1.16).

CONCLUSION

In this multicenter cohort of injured older adults with multiple rib fractures, RA use was associated with a 35% lower risk of delirium. Further studies are needed to standardize protocols for optimal pain management and prevention of delirium in older adults with severe thoracic injury.

Novel chest wall blocks for severe chest wall injuries in older persons: A case series

Patients over the age of 65 years admitted to hospital with more than six rib fractures have a mortality rate as high as 38%. Of the survivors, 34% are likely to be admitted to an aged care facility. High-quality analgesia is paramount to the mitigation of rib fracture–associated morbidity and mortality. We report a series of ten consecutive patients over the age of 65 years with more than eight fractured ribs. All patients were managed with a novel chest wall block. There were no deaths, and only one patient was discharged into an aged care facility.

Combination of the T7 Unilateral Erector Spinae Plane Block and T10 Bilateral Retrolaminar Blocks in a Patient with Multiple Rib Fractures on the Right and T10-12 Vertebral Compression Fractures: A Case Report

Multiple vertebral compression and rib fractures in elderly patients with pre-existing chronic obstructive pulmonary disease is a common scenario associated with significant morbidity and mortality. Severe pain prevents normal ventilation and leads to atelectasis, consolidation, and pneumonia. Subsequently, these patients frequently develop respiratory failure and require intubation and critical care. Therefore, adequate analgesia is often a life-saving intervention. Anesthetic management of a 78-year-old kyphotic patient with T6, T7, and T9 rib fractures on the right and T10-12 vertebral compression fractures sustained in an accidental fall is presented. She had inadequate pain control and was unable to take a deep breath or cough. Her respiratory status was deteriorating, with tachypnea and worsening hypoxia, necessitating bi-level positive airway pressure (BiPAP) support. Since thoracic epidural analgesia was contraindicated owing to compressive vertebral fractures and to the pending respiratory failure, we opted for a unilateral erector spinae plane (ESP) block at the T7 level and bilateral retrolaminar (RL) blocks at the T10 level. Following the procedure, the pain was immediately relieved and the patient was able to take deep breaths. Shortly thereafter, her respiratory status improved, with the respiratory rate coming back close to the baseline. The patient was subsequently weaned from BiPAP support and discharged from the intensive care unit. While the combination of ESP and RL blocks is not routinely used in patients with multiple rib and vertebral compression fractures, our report indicates that it may be an excellent alternative for analgesia in situations where thoracic epidural and/or paravertebral blocks are contraindicated and when timely intervention could be potentially life-saving.

Experimental study exploring the factors that promote rib fragility in the elderly

Rib fractures represent a common injury type due to blunt chest trauma, affecting hospital stay and mortality especially in elderly patients. Factors promoting rib fragility, however, are little investigated. The purpose of this in vitro study was to explore potential determinants of human rib fragility in the elderly. 89 ribs from 13 human donors (55–99 years) were loaded in antero-posterior compression until fracture using a material testing machine, while surface strains were captured using a digital image correlation system. The effects of age, sex, bone mineral density, rib level and side, four global morphological factors (e.g. rib length), and seven rib cross-sectional morphological factors (e.g. cortical thickness, determined by μCT), on fracture load were statistically examined using Pearson correlation coefficients, Mann–Whitney U test as well as Kruskal–Wallis test with Dunn-Bonferroni post hoc correction. Fracture load showed significant dependencies (p < 0.05) from bone mineral density, age, antero-posterior rib length, cortical thickness, bone volume/tissue volume ratio, trabecular number, trabecular separation, and both cross-sectional area moments of inertia and was significantly higher at rib levels 7 and 8 compared to level 4 (p = 0.001/0.013), whereas side had no significant effect (p = 0.989). Cortical thickness exhibited the highest correlation with fracture load (r = 0.722), followed by the high correlation of fracture load with the area moment of inertia around the longitudinal rib cross-sectional axis (r = 0.687). High correlations with maximum external rib surface strain were detected for bone volume/tissue volume ratio (r = 0.631) and trabecular number (r = 0.648), which both also showed high correlations with the minimum internal rib surface strain (r =  − 0.644/ − 0.559). Together with rib level, the determinants cortical thickness, area moment of inertia around the longitudinal rib cross-sectional axis, as well as bone mineral density exhibited the largest effects on human rib fragility with regard to the fracture load. Sex, rib cage side, and global morphology, in contrast, did not affect rib fragility in this study. When checking elderly patients for rib fractures due to blunt chest trauma, patients with low bone mineral density and the mid-thoracic area should be carefully examined.

Geriatric Trauma

Geriatric trauma patients will continue to increase in prevalence as the population ages, and many specific considerations need to be made to provide appropriate care to these patients. This article outlines common presentations of trauma in geriatric patients, with consideration to baseline physiologic function and patterns of injury that may be more prevalent in geriatric populations. Additionally, the article explores specific evidence-based management practices, the significance of trauma team and geriatrician involvement, and disposition decisions.

Trends in incidence rate, health care use, and costs due to rib fractures in the Netherlands

PURPOSE

This study aimed to examine population-based trends in the incidence rate, health care consumption, and work absence with associated costs in patients with rib fractures.

METHODS

A retrospective nationwide epidemiologic study was performed with data from patients with one or more rib fractures presented or admitted to a hospital in the Netherlands between January 1, 2015 and December 31, 2018 and have been registered in the Dutch Injury Surveillance System (DISS) or the Hospital Discharge Registry (HDR). Incidence rates were calculated using data from Statistics Netherlands. The associated direct health care costs, costs for lost productivity, and years lived with disability (YLD) were calculated using data from a questionnaire.

RESULTS

In the 4-year study period, a total of 32,124 patients were registered of which 19,885 (61.9%) required hospitalization with a mean duration of 7.7 days. The incidence rate for the total cohort was 47.1 per 100,000 person years and increased with age. The mean associated direct health care costs were €6785 per patient and showed a sharp increase after the age of 75 years. The mean duration of work absence was 44.2 days with associated mean indirect costs for lost productivity of €22,886 per patient. The mean YLD was 0.35 years and decreased with age.

CONCLUSION

Rib fractures are common and associated with lengthy HLOS and work absenteeism as well as high direct and indirect costs which appear to be similar between patients with one or multiple rib fractures and mostly affected by admitted patients and age.

Regional anaesthesia in the elderly patient a current perspective

PURPOSE OF REVIEW

The world's population is ageing. Although regional anaesthesia is well established, it seems there is limited evidence to support its use over general anaesthesia in the elderly. This review aims to examine recent publications of regional anaesthesia in relation to this specific patient subgroup.

RECENT FINDINGS

There is a paucity of evidence specifically relating to regional anaesthesia in the elderly patient. Studies tend to be small, retrospective and can combine assessment of multiple surgical and anaesthetic techniques in single studies. Surgical stimulus and the associated stress response are linked with an increased risk of morbidity in elderly patients. Regional anaesthesia is associated with reduced morbidity, improved pain scores, improved patient satisfaction and reduced resource allocation. Regional anaesthesia can potentially offset some of the surgical stress response and should be considered as part of a multimodal and, where possible, the primary approach to anaesthesia and analgesia in the elderly patient.

SUMMARY

Undoubtedly, peripheral nerve blocks improve analgesia and reduce opioid consumption and their associated side effects. This is beneficial in the perioperative care of elderly patients who may have less physiologic reserve to withstand these side effects. Future large prospective trials are required to evaluate the duration of action and safety profile of local anaesthetic agents and adjunct agents in the older patient.
