Tertiary survey in polytrauma patients should be an ongoing process

Clinical outcomes of trauma tertiary surveys conducted by allied health and non-medical healthcare professionals: A scoping review

BACKGROUND

The trauma tertiary survey (TTS) is a critical step in identifying missed injuries following primary and secondary trauma assessment. The TTS is traditionally performed by junior medical professionals on a trauma unit. Despite this, increasing trauma caseloads have led to challenges with TTS adherence, missed injuries and overwork. This has prompted interest into delegating some of the TTS tasks to non-medical professionals, however the efficacy and safety of this approach is poorly characterised.

METHODS

A scoping review was conducted following Joanna Briggs Institute methodology following a comprehensive search in Medline, Embase, Emcare and CINAHL databases. The search encompassed terms related to TTS and non-medical professionals. Outcomes were related to safety and efficacy of TTS performed by non-medical professionals.

RESULTS

Four observational studies involving trauma nurses (n = 3) and midlevel providers (n = 1) as non-medical providers of the TTS were included. Overall, there was evidence to suggest TTS performed by non-medical providers had similar missed injury detection rates and saved up to 1802 h of time for trauma residents. However, non-medical professionals demonstrated variable knowledge of TTS protocols, with gaps identified in training and experience.

CONCLUSION

TTS performed by non-medical professionals appears feasible and yields comparable clinical outcomes to medical staff, with potential to alleviate medical workforce pressures. These findings are based on studies of high clinical heterogeneity and poor control for confounders.

[Missed injuries in pediatric trauma care : Still a challenge]

Missed injuries (MI) in children and adolescents with multiple injuries represent a major challenge in pediatric trauma care despite the availability of standard examination protocols and imaging procedures. In the initial phase of care the primary survey is essentially important for the detection and treatment of life-threatening injuries and is well established. After stabilization of the patient in the trauma room and the first phase of treatment, a secondary survey and a tertiary survey should be carried out in order to detect initially MI in the further course and avoid longer term consequences. The majority of MI involve head, thoracic and extremity injuries. Risk factors for MI are younger patient age, the presence of multiple trauma, a higher injury severity score (ISS), a lower value on the Glasgow coma scale (GCS) and a prolonged stay in the intensive care unit. While MI are frequently described in severely or multiply injured children, a high proportion of MIs are also found in children transferred from other institutions. Therefore, two case studies from a pediatric trauma center at a maximum care hospital and a literature analysis are used to analyze typical MIs. These case examples underline the importance of adhering to a standardized treatment regimen for this patient group. It is advisable to develop a standard operating procedure (SOP) with a corresponding risk score, which regulates the tertiary survey, the times of the follow-up examinations and the corresponding (specialist) specific responsibilities.

Tertiary Trauma Survey on Emergency Department Observational Units: A Systematic Literature Review

In today's competitive world with a fast-paced lifestyle, trauma is on the rise and is globally recognized as the leading cause of mortality, morbidity, and disability. Despite the development of major trauma centers and the introduction of advanced trauma training courses and management guidelines, there remains a substantial risk of missed or delayed diagnosis of injuries with potentially life-changing physical, emotional, and financial implications. The proportion of such incidents is potentially higher in busy emergency departments and developing countries with fewer dedicated major trauma centers or where focused emergency and trauma training and skills development is still in its infancy. In the last decade, tertiary trauma surveys have been recognized as an important re-assessment protocol in reducing such missed injuries or delayed diagnoses in patients involved in major trauma. This naturally leads to the presumption that tertiary trauma surveys could also play an important role in observational medicine. This also brings into question whether a standardized tertiary trauma survey of major trauma patients on emergency observation units could reduce missed injuries, especially in low-income countries with fewer resources and trauma expertise. Thus, the purpose of this systematic literature review is to explore the potential role of tertiary trauma survey as a tool to reducing missed or delayed diagnosis in the emergency observation units and its applicability and feasibility in less-developed healthcare systems and in low- and middle-income countries. A broad-based systematic literature review was conducted to include electronic databases, grey literature, reference lists, and bibliographies using the keywords: tertiary trauma survey, major trauma, observational medicine, emergency observation units, clinical decision unit, adult, missed injuries, and delayed diagnosis. Over 19,000 citations were identified on initial search. Following a review of abstracts, application of inclusion and exclusion criteria, and review of the full article, 19 publications were finally selected for the purpose of this systematic literature review. Current evidence shows a general trend that tertiary trauma surveys performed 24 hours after admission play an important role in identifying injuries missed at the time of initial primary and secondary survey, and its implementation in observational medicine could prove beneficial, especially in resource-depleted healthcare systems.

Prevalence of Missed Injuries in Multiple Trauma Patients at a Level-1 Trauma Center in Saudi Arabia

Background Missed injuries are defined as injuries neither detected in the emergency department (ED) nor after admission to the hospital. The objective of this research was to identify missed injury rates, contributing factors, and clinical outcomes. Methods A total of 657 trauma patients' records were retrospectively reviewed after admission to King Abdulaziz Medical City (KAMC) during the period from January 2016 to December 2018. Patients' demographic characteristics, presence of a missed injury, and Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), and Injury Severity Score (ISS) were assessed. Results Among 657 patients who were admitted to our emergency department, only 11 (1.7%) patients were reported to have a missed injury during the hospital stay. None of those missed injuries contributed to the overall mortality. Higher GCS is a protective factor for missed injury with OR=0.12-0.81 and p-value=0.01. RTS and intensive care unit (ICU) stays were borderline although p-value=0.05 and OR=9 for RTS. Both longer ICU stays and high RTS were related to a higher risk of missed injury. Conclusion In our study, the prevalence of missed injuries was on the lower end of the spectrum in comparison to multiple published data. The most common missed injuries were fractures and joint dislocations of extremities. None of those missed injuries were life-threatening or contributed to overall mortality. Higher GCS was a protective factor against missed injuries while high RTS and longer ICU stays were related to a higher likelihood of developing missed injuries during the hospital course.

UK-wide major trauma center tertiary trauma survey pro forma review and aggregation and consolidation into a redesigned document

Objectives

The trauma tertiary survey (TTS) is an essential part of the continued care for major trauma patients which is performed to ensure that all injuries have been identified and none have been overlooked during the patient's stay. Although the Advanced Trauma Life Support Course states a need for a tertiary survey, there is currently no standard for what this survey comprises.

Methods

Using local consultant expert opinion and a literature search we identified a set of 32 TTS potential features that may be included within a TTS pro forma. Major trauma center (MTC) documents were requested from every MTC within the UK. 4 investigators sequentially interrogated each MTC TTS document looking for (1) presence of each feature and (2) how well the feature was represented on the document (0 to 4 Likert Scale). Any previously unidentified potential TTS features were noted and later reviewed for a second round of document analysis.

Results

A total of 21 out of all 26 UK MTCs had a TTS pro forma document. A total of 68 possible features were identified. Respiratory and Abdominal assessment sections were the most frequently identified features (present in 90.4% of the TTS pro formas; n=19. Neck assessment and neurological assessment were included within 85.7% of the TTS pro formas (n=18). Further aspects identified for Round 2 analysis typically included features that were thought to be important but highly specific. For example, pregnancy test and DNACPR discussions were found in 1 MTC TTS each (4%).

Conclusion

This article presents a review of the existing documents at 21 MTCs in the UK, identification of features used and proposes a gold standard TTS which can be used by any doctor to perform the tertiary survey and reduce the risk of missed injuries in trauma patients.

Accurate completion of tertiary trauma survey for inpatients at a non-trauma centre following significant trauma

INTRODUCTION

A tertiary trauma survey (TTS) is a structured, comprehensive top-to-toe examination following major trauma [1]. Literature suggests that the ideal time frame for the initial TTS should be completed within 24-hours of a patient's admission and repeated at important moments [2-4]. Evidence suggests that formal TTS reduces the rate of missed injuries by up to 38% [2].

AIMS

To determine the rate of TTS being conducted in trauma patients in a tertiary hospital without an admitting trauma service.

METHODS

We performed a retrospective analysis of adult trauma patients admitted to Middlemore Hospital (MMH) over six months. To be included, patients were either deemed to have a significant mechanism of injury or triggered a trauma call when arriving in the Emergency Department.

RESULTS

We identified 246 patients who met our criteria for requiring a TTS. 74 (30%) had a TTS completed. Of those completed, 22 (30%) were documented using a standardised form. 35 (47%) were done within the ideal timeframe (24 h); a further 21 (28%) were done within 48 h. House Officers (Junior Medical Officers) conducted the majority (80%), with the remainder being done by final-year medical students (12%), Registrars (Residents) (4%) and Consultants (Attendings) (4%). Of the 74 TTS that were completed, 21 (28%) detected a possible new injury, with 22% leading to further investigations being ordered. 14 (19%) were found to have a previously undetected, clinically significant injury on TTS (defined as 'injuries requiring further clinical intervention'). Most patients (90%) were admitted to either General Surgery or Orthopaedics. Sixty-two (54%) of patients admitted to General Surgery received a TTS; compared to just 11 (10%) admitted under Orthopaedics and 1 of 24 (4%) admitted to other specialities (including Hands, Plastics, Maxillo-Facial, Gynaecology and Medicine).

CONCLUSION

30% of patients requiring a TTS received one. 19% of TTS conducted detected clinically significant injuries.

Delayed diagnosed trauma in severely injured patients despite guidelines-oriented emergency room treatment: there is still a risk

Purpose

Emergency trauma room treatment follows established algorithms such as ATLS®. Nevertheless, there are injuries that are not immediately recognized here. The aim of this study was to evaluate the residual risk for manifesting life-threatening injuries despite strict adherence to trauma room guidelines, which is different to missed injuries that describe recognizable injuries.

Methods

In a retrospective study, we included 2694 consecutive patients admitted to the emergency trauma room of one single level I trauma center between 2016 and 2019. In accordance with the trauma room algorithm, primary and secondary survey, trauma whole-body CT scan, eFAST, and tertiary survey were performed. Patients who needed emergency surgery during their hospital stay for additional injury found after guidelines-oriented emergency trauma room treatment were analyzed.

Results

In seven patients (0.26%; mean age 50.4 years, range 18–90; mean ISS 39.7, range 34–50), a life-threatening injury occurred in the further course: one epidural bleeding (13 h after tertiary survey) and six abdominal hollow organ injuries (range 5.5 h–4 days after tertiary survey). Two patients (0.07% overall) with abdominal injury died. The “number needed to fail” was 385 (95%–CI 0.0010–0.0053).

Conclusion

Our study reveals a remaining risk for delayed diagnosis of potentially lethal injuries despite accurate emergency trauma room algorithms. In other words, there were missed injuries that could have been identified using this algorithm but were missed due to other reasons. Continuous clinical and instrument-based examinations should, therefore, not be neglected after completion of the tertiary survey.

The association of hand and wrist injuries with other injuries in multiple trauma patients. A retrospective study in a UK Major Trauma Centre

BACKGROUND

Approximately 20,000 major trauma cases occur in England every year. However, the association with concomitant upper limb injuries is unknown. This study aims to determine the incidence, injury pattern and association of hand and wrist injuries with other body injuries and the Injury Severity Score (ISS) in multiply injured trauma patients.

METHODS

Single centre retrospective study was performed at a level-one UK Major Trauma Centre (MTC). Trauma Audit and Research Network (TARN) eligible multiply injured trauma patients that were admitted to the hospital between January 2014 and December 2018 were analysed. TARN is the national trauma registry. Eligible patients were: a trauma patient of any age who was admitted for 72 h or more, or was admitted to intensive care, or died at the hospital, was transferred into the hospital for specialist care, was transferred to another hospital for specialist care or for an intensive care bed and whose isolated injuries met a set of criteria. Data extracted included: age, gender, mode of arrival, location of injuries including: hand and/or wrist and mechanism of injury. We performed a logistic regression analysis to assess the association between hand/wrist injury to ISS score of 15 points or above/below and to the presentation of other injuries.

RESULTS

107 patients were analysed. Hand and wrist injuries were the second most common injury (26.2%), after thoracic injuries. Distal radial injuries were found in 5.6%, carpal/carpometacarpal in 6.5%, concurrent distal radius and carpometacarpal in 0.9%, phalangeal injuries in 4.7%, tendon injuries in 0.9% and concurrent hand and wrist injuries in 7.5% cases. There was a significant association between hand or wrist injuries and lower limb injuries (Odds Ratio (OR): 3.84; 95% confidence intervals (CI): 1.09 to 13.50; p = 0.04) and pelvic injuries (OR: 4.78; 95% CI: 1.31 to 17.44; p = 0.02). There was no statistical association between hand and wrist injuries and ISS score (OR: 0.80; 95% CI: 0.11 to 5.79; p = 0.82).

CONCLUSIONS

Hand and wrist injuries are prevalent in trauma patients admitted to MTCs. They should not be under-estimated but routinely screened for in multiply injured patients particularly those with a pelvic or lower limb injury.

Traumatic rupture of the pectoralis major muscle with associated thrombosis of the cephalic vein as part of a seat belt injury following a motor vehicle accident: A case report

Traumatic rupture of the pectoralis major muscle is a rare concomitant injury in polytrauma patients often resulting in delayed diagnosis. We present the case of a young male patient who, among other injuries, suffered a complete rupture of the right-sided pectoralis major muscle at the humeral insertion point following a motor vehicle accident. Duplex sonography demonstrated an associated thrombosis of the cephalic vein, which was treated initially with intravenous heparin, and long-term with low-molecular weight heparin according to current guidelines. An open refixation of the muscle belly at the humeral insertion point was performed two weeks after the initial trauma. Post-operative follow-up presented a good overall outcome in terms of function and aesthetics. The authors emphasize the need of continuous clinical re-evaluation in the treatment of severely injured patients in order not to overlook relevant injuries.

Acromioclavicular and sternoclavicular joint dislocations indicate severe concomitant thoracic and upper extremity injuries in severely injured patients

Preliminary studies show that clavicle fractures (CF) are known as an indicator in the severely injured for overall injury severity that are associated with relevant concomitant injuries in the thorax and upper extremity. In this regard, little data is available for the rarer injuries of the sternoclavicular and acromioclavicular joints (SCJ and ACJ, respectively). Our study will answer whether clavicular joint injuries (CJI), by analogy, have a similar relevance for the severely injured. We performed an analysis from the TraumaRegister DGU (TR-DGU). The inclusion criterion was an Injury Severity Score (ISS) of at least 16. In the TR-DGU, the CJI were registered as one entity. The CJI group was compared with the CF and control groups (those without any clavicular injuries). Concomitant injuries were distinguished using the Abbreviated Injury Scale according to their severity. The inclusion criteria were met by n = 114,595 patients. In the case of CJI, n = 1228 patients (1.1%) were found to be less severely injured than the controls in terms of overall injury severity. Compared to the CF group (n = 12,030; 10.5%) with higher ISS than the controls, CJI cannot be assumed as an indicator for a more severe trauma; however, CF can. Concomitant injuries were more common for severe thoracic and moderate upper extremity injuries than other body parts for CJI. This finding confirms our hypothesis that CJI could be an indicator of further specific severe concomitant injuries. Despite the rather lower relevance of the CJI in the cohort of severely injured with regard to the overall injury severity, these injuries have their importance in relation to the indicator effect for thoracic concomitant injuries and concomitant injuries of the upper extremity. A limitation is the collective registration of SCJ and ACJ injuries as one entity in the TR-DGU. A distorted picture of the CJI in favor of ACJ injuries could arise from the significantly higher incidence of the ACJ dislocation compared to the SCJ. Therefore, these two injury entities should be recorded separately in the future, and prospective studies should be carried out in order to derive a standardized treatment strategy for the care of severely injured with the respective CJI.

European Society of Emergency Radiology: guideline on radiological polytrauma imaging and service (short version)

BACKGROUND

Although some national recommendations for the role of radiology in a polytrauma service exist, there are no European guidelines to date. Additionally, for many interdisciplinary guidelines, radiology tends to be under-represented. These factors motivated the European Society of Emergency Radiology (ESER) to develop radiologically-centred polytrauma guidelines.

RESULTS

Evidence-based decisions were made on 68 individual aspects of polytrauma imaging at two ESER consensus conferences. For severely injured patients, whole-body CT (WBCT) has been shown to significantly reduce mortality when compared to targeted, selective CT. However, this advantage must be balanced against the radiation risk of performing more WBCTs, especially in less severely injured patients. For this reason, we recommend a second lower dose WBCT protocol as an alternative in certain clinical scenarios. The ESER Guideline on Radiological Polytrauma Imaging and Service is published in two versions: a full version (download from the ESER homepage, https://www.eser-society.org ) and a short version also covering all recommendations (this article).

CONCLUSIONS

Once a patient has been accurately classified as polytrauma, each institution should be able to choose from at least two WBCT protocols. One protocol should be optimised regarding time and precision, and is already used by most institutions (variant A). The second protocol should be dose reduced and used for clinically stable and oriented patients who nonetheless require a CT because the history suggests possible serious injury (variant B). Reading, interpretation and communication of the report should be structured clinically following the ABCDE format, i.e. diagnose first what kills first.

The Impact of the Tertiary Survey in an Established Trauma Program

INTRODUCTION

The trauma tertiary survey (TTS) was first described in 1990 and is recognized as an essential practice in trauma care. The TTS remains effective in detecting secondary injuries in the modern era.

METHODS

Trauma patients discharged between August 1, 2016, and December 31, 2016, were identified in our trauma registry. Collected data include TTS completion rates, detection of injuries, type of provider, and timing. TTS documentation was qualitatively evaluated.

RESULTS

Out of 407 patients, 264 patients (65%) received a TTS. Injury detection rate was 1.1.%. Average time to TTS was 41 hours. TTS were completed by resident physicians (46%) and advanced practice providers (APPs; 46%). TTS documentation was more complete for APPs than for resident physicians.

CONCLUSION

TTS remains an integral component of modern trauma care. Ongoing education on the significance of TTS and the importance of thorough documentation is essential. Provision of real-time feedback to providers is also critical for improving current practices.

The yield of tertiary survey in patients admitted for observation after trauma

PURPOSE

Existing literature on trauma tertiary survey (TTS) focusses on multitrauma patients. This study examines the yield of the TTS in trauma patients with minor (AIS 1) or moderate (AIS 2) injury for which immediate hospitalization is not strictly indicated.

METHOD

A single center retrospective cohort study was performed in a level II trauma center. All hospitalized trauma patients with an abbreviate injury score (AIS) of one or two at the primary and secondary survey were included. The primary outcome was defined as any missed injury found during TTS (Type 1). Secondary outcomes were defined as any missed injury found after TTS but during admission (Type 2); overall missed injury rate; mortality and hospital length of stay.

RESULTS

Out of 388 included patients, 12 patients (3.1%) had a type 1 missed injury. ISS and alcohol consumption were associated with an increased risk for type 1 missed injuries (resp. OR = 1.4, OR = 5.49). A type 2 missed injury was only found in one patient. This concerned the only case of trauma related mortality. Approximately one out of five patients were admitted for more than 2 days. These patients were significantly older (66 vs. 41 years, p < 0.001), had a higher ISS (4 vs. 3, p = 0.007) and ASA score, 3-4 vs. 1-2 (42.5% vs. 12.6%, p < 0.001).

CONCLUSION

TTS showed a low rate of missed injuries in trauma patients with minor or moderate injury. TTS helped to prevent serious damage in two out of 388 patients (0.5%). ISS and alcohol consumption were associated with finding missed injury during TTS.

Correlating injury severity scores and major trauma volume using a state-wide in-patient administrative dataset linked to trauma registry data-A retrospective analysis from New South Wales Australia

INTRODUCTION

Trauma registries are used to analyse and report activity and benchmark quality of care at designated facilities within a trauma system. These capabilities may be enhanced with the incorporation of administrative and electronic medical record datasets, but are currently limited by the use of different injury coding systems between trauma and administrative datasets.

OBJECTIVES

Use an Abbreviated Injury Scale to International Classification of Disease (AIS-ICD) mapping tool to correlate estimated injury severity scores and major trauma volume based on administrative data collections with trauma registry data.

METHODS

Adult trauma cases were identified from the New South Wales Trauma Registry between 2012 and 2016 and linked probabilistically using age, facility and date of facility arrival to the Admitted Patient Data Collection (APDC). Estimated Injury Severity Scores (ISS) were derived using the AIS-ICD mapping tool applied to diagnoses contained in the APDC.

RESULTS

A total of eligible 13,439 cases were analysed. The overall correlation between trauma registry ISS and ISS estimated from APDC using the AIS-ICD mapping tool was low to moderate (Spearman Rho 0.41 95%CI 0.40, 0.43). Based on an estimated ISS cut-off value of 8, there was high correlation between estimated trauma volume and the number of major trauma cases at each facility (Spearman Rho 0.98, 95%CI 0.95, 0.99). Trauma Revised Injury Severity Score (TRISS) was associated with only slightly higher mortality prediction performance compared to estimated ISS (AUROC 0.76 95%CI 0.75, 0.78 versus AUROC 0.74 95%CI 0.73, 0.76).

CONCLUSION

A low to moderate correlation exists between individual patient ISS scores based on AIS to ICD mapping of in-patient data collection, but a high correlation for overall major trauma volume using the AIS-ICD mapping at facility level with comparable TRISS mortality prediction.

The evolution of trauma care in the Netherlands over 20 years

Introduction

In 1999 an inclusive trauma system was initiated in the Netherlands and a nationwide trauma registry, including all admitted trauma patients to every hospital, was started. The Dutch trauma system is run by trauma surgeons who treat both the truncal (visceral) and extremity injuries (fractures).

Materials and Methods

In this comprehensive review based on previous published studies, data over the past 20 years from the central region of the Netherlands (Utrecht) was evaluated.

Results

It is demonstrated that the initiation of the trauma systems and the governance by the trauma surgeons led to a region-wide mortality reduction of 50% and a mortality reduction for the most severely injured of 75% in the level 1 trauma centre. Furthermore, major improvements were found in terms of efficiency, demonstrating the quality of the current system and its constructs such as the type of surgeon. Due to the major reduction in mortality over the past few years, the emphasis of trauma care evaluation shifts towards functional outcome of severely injured patients. For the upcoming years, centralisation of severely injured patients should also aim at the balance between skills in primary resuscitation and surgical stabilization versus longitudinal surgical involvement.

Conclusion

Further centralisation to a limited number of level 1 trauma centres in the Netherlands is necessary to consolidate experience and knowledge for the trauma surgeon. The future trauma surgeon, as specialist for injured patients, should be able to provide the vast majority of trauma care in this system. For the remaining part, intramural, regional and national collaboration is essential

ICU Management of Trauma Patients

OBJECTIVES

To describe the current state of the art regarding management of the critically ill trauma patient with an emphasis on initial management in the ICU.

DATA SOURCES AND STUDY SELECTION

A PubMed literature review was performed for relevant articles in English related to the management of adult humans with severe trauma. Specific topics included airway management, hemorrhagic shock, resuscitation, and specific injuries to the chest, abdomen, brain, and spinal cord.

DATA EXTRACTION AND DATA SYNTHESIS

The basic principles of initial management of the critically ill trauma patients include rapid identification and management of life-threatening injuries with the goal of restoring tissue oxygenation and controlling hemorrhage as rapidly as possible. The initial assessment of the patient is often truncated for procedures to manage life-threatening injuries. Major, open surgical procedures have often been replaced by nonoperative or less-invasive approaches, even for critically ill patients. Consequently, much of the early management has been shifted to the ICU, where the goal is to continue resuscitation to restore homeostasis while completing the initial assessment of the patient and watching closely for failure of nonoperative management, complications of procedures, and missed injuries.

CONCLUSIONS

The initial management of critically ill trauma patients is complex. Multiple, sometimes competing, priorities need to be considered. Close collaboration between the intensivist and the surgical teams is critical for optimizing patient outcomes.

Foot fractures in polytrauma patients: Injury characteristics and timing of diagnosis

BACKGROUND

Due to prioritizing care and concomitant injuries, foot fractures in polytrauma patients often receive limited attention initially. However, as foot function is important, treatment and diagnosis of these fractures should be accurate. The aims of this study were to assess the incidence and distribution of foot fractures in polytrauma patients and to examine possible risk factors for delayed diagnosis of foot fractures.

METHODS

This was a retrospective study on all adult (≥18 years) polytrauma (ISS ≥16) patients admitted to a single level 1 trauma center between 2006 and 2016. Patients with foot fractures were identified by diagnosis codes. Data on demographics and trauma characteristics were collected from the Trauma Quality Improvement Program (TQIP^®) database. Data on foot fractures were gathered from electronic patient documentation.

RESULTS

Out of 4409 polytrauma patients, 221 (5.0%) sustained a total of 511 foot fractures. Metatarsal fractures were most common (41%), followed by calcaneal (17%), and talar (16%) fractures. Thirty percent of the fractures in 33% of all patients were diagnosed in a delayed fashion. This had treatment consequences in 8%. Delayed diagnosed fractures were more common in older patients (p 0.025), patients with a higher ISS (p 0.012), ICU admission (p 0.015), and concomitant head injury (p 0.020).

CONCLUSIONS

As one in twenty polytrauma patients sustains at least one foot fracture and a substantial amount of these fractures are diagnosed in a delayed fashion, physicians, regardless of their specialty, should have a high index of suspicion for injuries of the feet in polytrauma patients.

Epidemiology of distal radius fractures in polytrauma patients and the influence of high traumatic energy transfer

INTRODUCTION

For several extremity fractures differences in morphology, incidence rate and functional outcome were found when polytrauma patients were compared to patients with an isolated injury. This is not proven for distal radius fractures (DRF). Therefore, this study aimed to analyse fracture morphology in relation to energy transfer in both poly- and mono-trauma patients with a DRF.

METHODS

This was a retrospective cohort study. All patients aged 16 years and older with a DRF were included. Patients with an Injury Severity Score of 16 or higher were classified as polytrauma patients. Injuries were defined as high or low energy. All DRFs were classified using the AO/OTA fracture classification system.

RESULTS

A total of 830 patients with a DRF were included, 12% were polytrauma. The incidence rate of DRF in polytrauma patients was 3.5%. Ipsilateral upper extremity injury was found in >30% of polytrauma and high-energy monotrauma patients, compared to 5% in low-energy monotrauma patients. More type C DRF were found in polytrauma and high-energy monotrauma patients versus low-energy monotrauma patients. Operative intervention rates for all types of DRF were similar for polytrauma and high-energy monotrauma patients. Non-union rates were higher in polytrauma patients.

CONCLUSION

Higher energy mechanisms of injury, in polytrauma and high-energy monotrauma patients, were associated with more severe complex articular distal radius fractures and more ipsilateral upper extremity injuries. Polytrauma and high-energy monotrauma patient have a similar fracture morphology. However, polytrauma patients have in addition to more injured body regions also more non-union related interventions than high-energy monotrauma patients.

Fractures and dislocations of the hand in polytrauma patients: Incidence, injury pattern and functional outcome

INTRODUCTION

Injuries of the hand can cause significant functional impairment, diminished quality of life and delayed return to work. However, the incidence and functional outcome of hand injuries in polytrauma patients is currently unknown. The aim of this study was to determine the incidence, distribution and functional outcome of fractures and dislocation of the hand in polytrauma patients.

METHODS

A single centre retrospective cohort study was performed at a level 1 trauma centre. Polytrauma was defined as patients with an Injury Severity Score of 16 or higher. Fractures and dislocations to the hand were determined. All eligible polytrauma patients with hand injuries were included and a Quick Disability of Arm, Shoulder and Hand questionnaire (QDASH) and Patient-Rated Wrist/Hand Evaluation (PRWHE) were administered. Patients were contacted 1-6 years after trauma.

RESULTS

In a cohort of 2046 polytrauma patients 72 patients (3.5%) suffered a hand injury. The functional outcome scores of 52 patients (72%) were obtained. The Metacarpal (48%) and carpal (33%) bones were the most frequently affected. The median QDASH score for all patients with hand injury was 17 (IQR 0-31) and the PRWHE 14 (IQR 0-41). Patients with a concomitant upper extremity injury (p=0.002 for PRWHE, p0.006 for QDASH) and those with higher ISS scores (p=0.034 for PRWHE, QDASH not significant) had worse functional outcome scores. As an example, of the 5 patients with the worst outcome scores 3 suffered an isolated phalangeal injury, all had concomitant upper extremity injury or neurological injuries (3 plexus injuries, 1 severe brain injury).

CONCLUSION

The incidence of hand injuries in polytrauma patients is 3.5%, which is relatively low compared to a general trauma population. Metacarpal and carpal bones were most frequently affected. The functional extremity specific outcome scores are highly influenced by concomitant injuries (upper extremity injuries, neurological injuries and higher ISS).

Comparing fracture healing disorders and long-term functional outcome of polytrauma patients and patients with an isolated displaced midshaft clavicle fracture

BACKGROUND

Although clavicle fractures are a common injury in polytrauma patients, the functional outcome of displaced midshaft clavicle fractures (DMCFs) in this population is unknown. Our hypothesis was that there would be no differences in fracture healing disorders or functional outcome in polytrauma patients with a DMCF compared with patients with an isolated DMCF, regardless of the treatment modality.

METHODS

A retrospective cohort study of patients (treated at our level I trauma center) with a DMCF was performed and a follow-up questionnaire was administered. Polytrauma patients, defined as an Injury Severity Score ≥16, and those with an isolated clavicle fracture were compared. Fracture healing disorders (nonunion and delayed union) and delayed fixation rates were determined. Functional outcome was assessed by the Quick Disability of the Arm, Shoulder, and Hand questionnaire.

RESULTS

A total of 152 patients were analyzed, 71 polytrauma patients and 81 patients with an isolated DMCF. Questionnaire response of 121 patients (80%) was available (mean, 53 months; standard deviation, 22 months). No differences were found between polytrauma patients and those with an isolated DMCF with regard to nonunion (7% vs. 5%, respectively), delayed union (4% vs. 4%), and delayed fixation rate (13% vs. 13%). Polytrauma patients had an overall worse functional outcome, regardless of initial nonoperative treatment or delayed operative fixation.

CONCLUSION

Polytrauma patients had a similar nonunion and delayed fixation rate but had an overall worse functional outcome compared with patients with an isolated DMCF. For polytrauma patients, a wait and see approach can be advocated without the risk of decreased upper extremity function after delayed fixation.

Management of polytrauma patients in the UK: Is there a 'weekend effect'?

BACKGROUND/PURPOSE

It has been suggested that hospital admission during weekends poses a risk for adverse outcomes and increased patient mortality, the so-called 'weekend effect'. We undertook an evaluation of the impact of weekend admissions to the management of polytraumatised patients, in a Level I Major Trauma Centre (MTC) in the UK.

MATERIALS AND METHODS

A retrospective review of prospectively documented data of polytrauma patients (injury severity score (ISS)>15), admitted between April 2013 and August 2015 was performed. Exclusion criteria included patients initially assessed in other institutions. All patients were initially managed at the emergency department (ED) according to ATLS^® principles and underwent a trauma computed tomography (CT) scan, unless requiring immediate surgical intervention.

RESULTS

During the study period 1735 patients (pts) were admitted under the care of the MTC. Four hundred and five pts were excluded as they were transferred from other institutions and 300 pts were excluded as their ISS was less than 16. Overall 1030 patients met the inclusion criteria, out of which 731 were males. Comparing the two groups (Group A: weekday admissions (670), Group B: weekend admissions (360)), there was no difference in pts gender, mechanism of injury, GCS at presentation, need for intubation and time to CT. Patients admitted over the weekend were younger (p<0.01) and presented with haemodynamic instability more frequently (p=0.02). Time to operating room was also lower during the weekend, but this did not reach statistical significance (p=0.08). Mortality was lower in Group B: 39/360 pts (10.8%) compared to Group A: 100/670 pts (14.9%) (p=0.07). The relative risk (RR) of weekend mortality was calculated as 0.726 (95% CI: 0.513-1.027).

DISCUSSION/CONCLUSION

Weekend polytrauma patients appear to be younger, more severely injured and present with a higher incidence of haemodynamic instability (shock). Overall, we failed to identify a "weekend effect" in relation to mortality, time to CT and time to operating room. On the contrary, a lower risk of mortality was noted for patents admitted during the weekend.
