Interpretation and reporting of predictive or diagnostic machine-learning research in Trauma & Orthopaedics.

There is increasing popularity in the use of artificial intelligence and machine-learning techniques to provide diagnostic and prognostic models for various aspects of Trauma & Orthopaedic surgery. However, correct interpretation of these models is difficult for those without specific knowledge of computing or health data science methodology. Lack of current reporting standards leads to the potential for significant heterogeneity in the design and quality of published studies. We provide an overview of machine-learning techniques for the lay individual, including key terminology and best practice reporting guidelines.

A Culture Change in Geriatric Traumatology: Holistic and Patient-Tailored Care for Frail Patients with Fractures.

ABSTRACT: Medical decision-making for frail geriatric trauma patients is complex, especially toward the end of life. The goal of this paper is to review aspects of end-of-life decision-making, such as frailty, cognitive impairment, quality of life, goals of care, and palliative care. Additionally, we make recommendations for composing a patient-tailored treatment plan. In doing so, we seek to initiate the much-needed discussion regarding end-of-life care for frail geriatric patients.

The result of the use of remote consultation in orthopaedic and trauma surgery during the COVID-19 pandemic.

The COVID pandemic has made telematic consultations a basic tool in daily practice. AIMS: The main objective of the study is to assess the results of the application of telematic consultations to limit the mobility of patients.The operational objectives are; to propose a consultation plan, to know how attendance limits consultations and to define which pathologies benefit the most from this plan. METHODS: A scheme is proposed with the creation of pre-scheduled clinic to assess suitability and the possibility of carrying them out in a single non face-to-face act. RESULTS: Phone call to 5619 patients were made with a lack of response of 19%The cases of 74% of the patients that answered were resolved virtually. There is a difference between units, obtaining a higher answering rate from patients appointed to specific clinic units, OR = 0.60, or to general trauma ones, OR = 0.67. The lowest answering rate was obtained from those derived from the emergency department.Twenty per cent of the consultations were not accompanied by complementary tests that would have favored the resolution in a single act. The general trauma consultations, OR = 0.34, postoperative control, OR = 0.49, and specific unit ones, OR = 0.40, were the ones that better met this requirement.Out of the remaining patients, the general trauma consultations, OR = 0.50, and those referred to units, OR = 0.54, were the ones that had a higher resolution rate without in- person consultation. CONCLUSIONS: The cases of 74% of the patients who answered the phone call were resolved virtually.Cases of 20% of the patients cannot be solved in a single act because they are derived without complementary tests.Osteosynthesis and postoperative arthroscopic follow-up consultations are the ones that need to be carried out in person the most.

Las consultas de traumatología general, OR = 0.34, control postoperatorio, OR = 0.49, y unidades, OR = 0.40, cumplieron mejor este requisito.De los pacientes restantes, las consultas de traumatología general, OR = 0.50, y las derivadas a unidades, OR = 0.54, fueron las que se mas se resolvieron sin acudir presencialmente. CONCLUSIONES: Se han resuelto de forma no presencial el 74% de los pacientes que atendieron a la llamada telefónica. El 20% de los pacientes acuden a la visita sin pruebas complementarias. Las consultas de seguimiento de osteosíntesis y postoperatorio de cirugía artroscópica son las que mas precisan de ser realizadas de forma presencial.

Augmented reality visualization tool for the future of tactical combat casualty care.

ABSTRACT: The objective of this project was to identify and develop software for an augmented reality application that runs on the US Army Integrated Visual Augmentation System (IVAS) to support a medical caregiver during tactical combat casualty care scenarios. In this augmented reality tactical combat casualty care application, human anatomy of individual soldiers obtained predeployment is superimposed on the view of an injured war fighter through the IVAS. This offers insight into the anatomy of the injured war fighter to advance treatment in austere environments.In this article, we describe various software components required for an augmented reality tactical combat casualty care tool. These include a body pose tracking system to track the patient's body pose, a virtual rendering of a human anatomy avatar, speech input to control the application and rendering techniques to visualize the virtual anatomy, and treatment information on the augmented reality display. We then implemented speech commands and visualization for four common medical scenarios including injury of a limb, a blast to the pelvis, cricothyrotomy, and a pneumothorax on the Microsoft HoloLens 1 (Microsoft, Redmond, WA).The software is designed for a forward surgical care tool on the US Army IVAS, with the intention to provide the medical caregiver with a unique ability to quickly assess affected internal anatomy. The current software components still had some limitations with respect to speech recognition reliability during noise and body pose tracking. These will likely be improved with the improved hardware of the IVAS, which is based on a modified HoloLens 2.

Optimizing a decision support system for damage-control resuscitation using mixed methods human factors analysis.

BACKGROUND: Damage-control resuscitation (DCR) improves trauma survival; however, consistent adherence to DCR principles through multiple phases of care has proven challenging. Clinical decision support may improve adherence to DCR principles. In this study, we designed and evaluated a DCR decision support system using an iterative development and human factors testing approach. METHODS: The phases of analysis included initial needs assessment and prototype design (Phase 0), testing in a multidimensional simulation (Phase 1), and testing during initial clinical use (Phase 2). Phase 1 and Phase 2 included hands-on use of the decision support system in the trauma bay, operating room, and intensive care unit. Participants included trauma surgeons, trauma fellows, anesthesia providers, and trauma bay and intensive care unit nurses who provided both qualitative and quantitative feedback on the initial prototype and all subsequent iterations. RESULTS: In Phase 0, 14 (87.5%) of 16 participants noted that they would use the decisions support system in a clinical setting. Twenty-four trauma team members then participated in simulated resuscitations with decision support where 178 (78.1%) of 228 of tasks were passed and 27 (11.8%) were passed with difficulty. Twenty-three (95.8%) completed a postsimulation survey. Following iterative improvements in system design, Phase 2 evaluation included 21 trauma team members during multiple real-world trauma resuscitations. Of these, 15 (71.4%) completed a formal postresuscitation survey. Device-level feedback on a Likert scale (range, 0-4) confirmed overall ease of use (median score, 4; interquartile range, 4-4) and indicated the system integrated well into their workflow (median score, 3; interquartile range, 2-4). Final refinements were then completed in preparation for a pilot clinical study using the decision support system. CONCLUSIONS: An iterative development and human factors testing approach resulted in a clinically useable DCR decision support system. Further analysis will determine its applicability in military and civilian trauma care. LEVEL OF EVIDENCE: Therapeutic/Care Management, Level V.

Choosing wisely: A prospective study of direct to operating room trauma resuscitation including real-time trauma surgeon after-action review.

INTRODUCTION: Although several centers have direct to operating room (DOR) resuscitation programs, there are no published prospective studies on optimal patient selection, interventions, outcomes, or real-time surgeon assessments. METHODS: Direct to operating room cases for 1 year were prospectively enrolled. Demographics, injury types/severity, triage criteria, interventions, and outcomes including Glasgow Outcome Scale score were collected. Detailed time-to-event and sequence data on initial lifesaving interventions (LSIs) or emergent surgeries were analyzed. A structured real-time attending surgeon assessment tool for each case was collected. Direct to operating room activation criteria were grouped into categories: mechanism, physiology, injury pattern, or emergency medical services (EMS) suspicion. RESULTS: There were 104 DOR cases: male, 84%; penetrating, 80%; and severely injured (Injury Severity Score, >15), 39%. The majority (65%) required at least one LSI (median of 7 minutes from arrival), and 41% underwent immediate emergent surgery (median, 26 minutes). Blunt patients were more severely injured and more likely to undergo LSI (86% vs. 59%) but less likely to require emergent surgery (19% vs. 47%, all p < 0.05). Analysis of DOR criteria categories showed unique patterns in each group for interventions and outcomes, with EMS suspicion associated with the lowest need for DOR. Surgeon assessment tool results found that DOR was indicated in 84% and improved care in 63%, with a small subset identified (9%) where DOR had a negative impact. CONCLUSION: Direct to operating room resuscitation facilitated timely emergent interventions in penetrating truncal trauma and a select subset of critically ill blunt patients. Unique intervention/outcome profiles were identified by activation criteria groups, with little utility among activations for EMS suspicion. Real-time surgeon assessment tool identified high- and low-yield DOR groups. LEVEL OF EVIDENCE: Prospective observational study, level III.

Modifiable factors to improve work-life balance for trauma surgeons.

INTRODUCTION: A balance between work and life outside of work can be difficult for practicing physicians to achieve, especially for trauma surgeons. Work-life balance (WLB) has been associated with burnout and career changes. The specific aim of this study was to investigate factors associated with WLB for trauma surgeons. We hypothesized that trauma surgeons are dissatisfied with their WLB, and there are modifiable factors that can be adjusted to improve and maintain WLB. METHODS: Survey study of AAST members including detailed questions regarding demographics, clinical practice, family, lifestyle, and emotional support. Primary outcome was WLB, while the secondary outcome was surgeon burnout. RESULTS: A total of 1,383 American Association for the Surgery of Trauma members received an email with the survey, and 291 (21%) completed the survey. There was a total of 125 members (43%) satisfied with their WLB, and 166 (57%) were not. Factors independently associated with satisfying WLB included hobbies (2.3 [1.1-4.7], p = 0.03), healthy diet (2.6 [1.2-4.4], p = 0.02), exercise (2.6 [1.3-5.1], p = 0.006), vacation weeks off (1.3 [1.0-1.6], p = 0.02), and fair compensation (2.6 [1.3-5.3], p = 0.008). Conversely, factors independently associated with a poor WLB included being midcareer (0.3 [0.2-0.7], p = 0.002), more work hours (0.4 [0.2-0.7], p = 0.006), fewer awake hours at home (0.2 [0.1-0.6], p = 0.002), and feeling that there is a better job (0.4 [0.2-0.9], p = 0.02]. Risk factors for burnout were the same as those for poor WLB. CONCLUSION: Only 43% of trauma surgeons surveyed were satisfied with their WLB, and 61% reported burnout. Modifiable factors independently associated with a satisfying WLB were related to lifestyle and fair compensation. Factors independently associated with poor WLB and suffering burnout were being midcareer, increased hours at work, decreased awake hours at home, and feeling that there was a better job for yourself. Many factors associated with trauma surgeon WLB are modifiable. Trauma surgeons, as well as trauma leaders, should focus on these modifiable factors to optimize WLB and minimize burnout.

Aerosol generating procedures in trauma and orthopaedics in the era of the Covid-19 pandemic; What do we know?

PURPOSE: COVID-19 pandemic has created havoc all over the globe and spared no one regardless of status, gender, location and ethnicity. There were questions raised if trauma and orthopaedic (T&O) procedures actually generated aerosols? The need for a review of literature highlighting the nature and impact of aerosol generation within T&O surgery was noted. METHODS: A comprehensive online search was performed for all published articles in the English language, evaluating AGPs in T&O surgery and the relevant personal protection equipment used. RESULTS: The search strategy populated 43 studies. Six studies were identified as duplicates. The shortlisted 37 studies were screened and nine studies were included in the review. An additional four studies were included from the bibliography review. CONCLUSION: Most orthopaedic procedures are high-risk aerosol generating procedures (AGPs). Conventional surgical masks do not offer protection against high-risk AGPs. In the current era of COVID-19 pandemic, there is a significant risk to the transmission of infection to the theatre staff. For protection against airborne transmission, appropriate masks should be used. These need proper fitting and sizing to ensure full protection when used.

Equity on the frontlines of trauma surgery: An #EAST4ALL roundtable.

BACKGROUND: Inequity exists in surgical training and the workplace. The Eastern Association for the Surgery of Trauma (EAST) Equity, Quality, and Inclusion in Trauma Surgery Ad Hoc Task Force (EAST4ALL) sought to raise awareness and provide resources to combat these inequities. METHODS: A study was conducted of EAST members to ascertain areas of inequity and lack of inclusion. Specific problems and barriers were identified that hindered inclusion. Toolkits were developed as resources for individuals and institutions to address and overcome these barriers. RESULTS: Four key areas were identified: (1) harassment and discrimination, (2) gender pay gap or parity, (3) implicit bias and microaggressions, and (4) call-out culture. A diverse panel of seven surgeons with experience in overcoming these barriers either on a personal level or as a chief or chair of surgery was formed. Four scenarios based on these key areas were proposed to the panelists, who then modeled responses as allies. CONCLUSION: Despite perceived progress in addressing discrimination and inequity, residents and faculty continue to encounter barriers at the workplace at levels today similar to those decades ago. Action is needed to address inequities and lack of inclusion in acute care surgery. The EAST is working on fostering a culture that minimizes bias and recognizes and addresses systemic inequities, and has provided toolkits to support these goals. Together, we can create a better future for all of us.

A Review of "Changes in the Management of Injuries to the Liver and Spleen" (2005).

Introduction: The article "Changes in the Management of Injuries to the Liver and Spleen" was originally presented as the Scudder Oration on Trauma at the American College of Surgeons' (ACS) 90th Annual Clinical Congress in New Orleans, Louisiana, in October 2004. Charles L. Scudder, MD, a founding member of the College, was the originator and first Chairman of the Committee on the Treatment of Fractures from 1922 to 1933. The first "Fracture Oration" of the ACS by Dr Scudder was entitled "Oration on Fractures," was presented at the Clinical Congress in October 1929, and was published in Surg Gynecol Obstet 1930; 50:193-195. Fracture Orations were presented from 1929 to 1941 and 1946 to 1951, while an Oration on Trauma was presented from 1952 to 1962. From 1963 to present, the Scudder Oration on Trauma has been presented at the annual Clinical Congress by an individual with significant contributions to the field.

A Review of "Prehospital Hypotension as a Valid Indicator of Trauma Team Activation" (2000).

Prehospital hypotension has been utilized for decades as a surrogate marker of injury severity. Several studies have discussed the correlation between injury and hypotension both in the field as well as in the emergency department. Increases have been noted in injury severity score and mortality. Resource utilization is higher in this patient population. This study revisits our original work from 2000 and reviews the current literature regarding hypotension and injury severity. We also examine the role of prehospital hypotension as an indicator of trauma team activation and resource allocation. This review serves as a part of a Literary Festschrift in honor of Dr J David Richardson's role as the Editor-in-Chief of The American Surgeon.

The lowest answering rate was obtained from those derived from the emergency department. Twenty per cent of the consultations were not accompanied by complementary tests that would have favored the resolution in a single act. The general trauma consultations, OR = 0.34, postoperative control, OR = 0.49, and specific unit ones, OR = 0.40, were the ones that better met this requirement. Out of the remaining patients, the general trauma consultations, OR = 0.50, and those referred to units, OR = 0.54, were the ones that had a higher resolution rate without in- person consultation. CONCLUSIONS: The cases of 74% of the patients who answered the phone call were resolved virtually. Cases of 20% of the patients cannot be solved in a single act because they are derived without complementary tests. Osteosynthesis and postoperative arthroscopic follow-up consultations are the ones that need to be carried out in person the most.

Effective Palliative Care in the Trauma Setting.

A 55-year-old man undergoes emergent exploratory laparotomy and splenectomy following a motorcycle collision. Following surgery, he is found to have a traumatic brain injury requiring decompressive craniectomy and intracranial pressure monitoring. The patient then continues to have complications throughout his hospital course. Using the American College of Surgeons Trauma Quality Improvement Program guidelines, the surgical team has early and ongoing primary palliative care discussions to foster communication and determine goals of care for the patient. As the patient deteriorates, the surgical team continues meeting with the patient's surrogate decision makers to discuss the best case and worst case scenarios regarding the patient's prognosis and expected quality of life.

The Israel Defense Forces Trauma Registry: 22 years of point-of-injury data.

BACKGROUND: Trauma is the leading cause of death among casualties between 1 and 44 years. A large proportion of trauma deaths occurs even before arriving at a medical facility. The paucity of prehospital data is a major reason for the lagging development of prehospital trauma care research. This study aims to describe the Israel Defense Forces Prehopistal Trauma Registry, the steps taken to improve data collection and quality, the resulting trends, and the registry's contribution to policymaking. METHODS: This study explores the quantity and quality of point of injury and prehospital data in the registry between the years 1997 and 2018. We assessed the number of recorded casualties per year, casualties characteristics, and documentation variables in the registry, with a specific focus on documentation of vital signs throughout the years. RESULTS: Overall, 17,905 casualties were recorded. Most casualties were young males (88.6%)-military personnel (52.7%), Syrian refugees (16.2%), Israeli civilians (11.5%), and Palestinians (9.0%). The median number of annual records from 2006 onward was significantly higher compared with before 2006 (1,000 [IQR, 792-1,470] vs. 142 [IQR, 129-156]). Between 2010 and 2018, documentation rate increased in all vital signs investigated including heart rate (56.3% vs. 1.0%), level of consciousness (55.1% vs. 0.3%), respiratory rate (51.8% vs. 0.3%), blood oxygen saturation (50.0% vs. 1.0%), Glasgow Coma Scale (48.2% vs. 0.4%), systolic blood pressure (45.7% vs. 0.8%), and pain (19.1% vs. 0.5%). CONCLUSION: Point of injury and prehospital documentation are rare yet essential for ongoing improvement of combat casualty care. The Israel Defense Forces Trauma Registry is one of the largest and oldest prehospital computerized military trauma registries in the world. This study shows a major improvement in the quantity and then in the quality of prehospital documentation throughout the years that affected guidelines and policy. Further work will focus on improving data completeness and accuracy. LEVEL OF EVIDENCE: Retrospective study, level III.

Evaluation and management of blunt cerebrovascular injury: A practice management guideline from the Eastern Association for the Surgery of Trauma.

BACKGROUND: Blunt cerebrovascular injuries (BCVIs) are associated with significant morbidity and mortality. This guideline evaluates several aspects of BCVI diagnosis and management including the role of screening protocols, criteria for screening cervical spine injuries, and the use of antithrombotic therapy (ATT) and endovascular stents. METHODS: Using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, a taskforce of the Practice Management Guidelines Committee of the Eastern Association for the Surgery of Trauma performed a systematic review and meta-analysis of currently available evidence. Four population, intervention, comparison, and outcome questions were developed to address diagnostic and therapeutic issues relevant to BCVI. RESULTS: A total of 98 articles were identified. Of these, 23 articles were selected to construct the guidelines. In these studies, the detection of BCVI increased with the use of a screening protocol versus no screening protocol (odds ratio [OR], 4.74; 95% confidence interval [CI], 1.76-12.78; p = 0.002), as well as among patients with high-risk versus low-risk cervical spine injuries (OR, 12.7; 95% CI, 6.24-25.62; p = 0.003). The use of ATT versus no ATT resulted in a decreased risk of stroke (OR, 0.20; 95% CI, 0.06-0.65; p < 0.0001) and mortality (OR, 0.17; 95% CI, 0.08-0.34; p < 0.0001). There was no significant difference in the risk of stroke among patients with Grade II or III injuries who underwent stenting as an adjunct to ATT versus ATT alone (OR, 1.63; 95% CI, 0.2-12.14; p = 0.63). CONCLUSION: We recommend using a screening protocol to detect BCVI in blunt polytrauma patients. Among patients with high-risk cervical spine injuries, we recommend screening computed tomography angiography to detect BCVI. For patients with low-risk risk cervical injuries, we conditionally recommend performing a computed tomography angiography to detect BCVI. We recommend the use of ATT in patients diagnosed with BCVI. Finally, we recommend against the routine use of endovascular stents as an adjunct to ATT in patients with Grade II or III BCVIs. LEVEL OF EVIDENCE: Guidelines, Level III.

A standardized trauma-specific endovascular inventory.

We believe that the rapid and widespread adoption of resuscitative endovascular balloon occlusion of the aorta as well as enthusiasm for catheter-based strategies has led to increased interest in basic endovascular techniques among trauma surgeons. The aim of this article was to describe the most commonly performed endovascular procedures for trauma patients, the basic capital equipment and room set up, and a parsimonious inventory of disposable supplies needed to perform each procedure. Together, these make a standardized trauma-specific endovascular inventory. LEVEL OF EVIDENCE: Economic/decision, level V.

Correlación funcional radiológica en pacientes tratados mediante osteotomía de SCARF en el servicio de traumatología y ortopedia del Hospital Obrero N° 1, durante las gestiones 2011 ­ 2016 / Functional radiological correlationship in patients treated by SCARF osteotomy in the traumatology and orthopedics service of Hospital Obrero No. 1, term 2011 ­ 2016

INTRODUCCIÓN: la marcha es una actividad compleja, que requiere de un balance estricto, donde toda la extremidad inferior actúa de manera conjunta para realizar el movimiento y donde el pie es la única parte que actúa sobre el suelo. Por ello cualquier alteración anatómica y biomecánica del pie repercute en la ambulación. OBJETIVO: determinar el grado de correlación funcional ­ radiológica en pacientes tratados mediante osteotomía de scarf. MATERIAL Y MÉTODOS: rstudio correlacional y transversal. Se estudiaron 78 pacientes con diagnóstico de hallux valgus. Se realizó la valoración funcional (Escala AOFAS) y radiológica de todos los pacientes con hallux valgus operados mediante la osteotomía de scarf; se estableció además la correlación entre la valoración funcional y radiológica de cada paciente mediante la prueba de chi cuadrado. RESULTADOS: habiéndose obtenido el valor crítico de Chi ­ cuadrado (X2 c = 12.992), se comprobó que este es menor que el valor del Chi ­ cuadrado calculado, tanto para el ángulo metatarso-falángico (X2 = 40.715) y el ángulo inter-metatarsiano (X2 = 16.539); lo que significa que la hipótesis nula no se aceptó (Los resultados funcionales no se correlacionan con los resultados radiológicos de manera inversamente proporcional). CONCLUSIÓN: se determinó un grado de correlación inverso entre los resultados funcionales y radiológicos en pacientes tratados mediante osteotomía de scarf; α = 0.05; p = 0.95. Significa que a mayor gradación de hallux valgus (leve, moderado y severo), menor es el puntaje de la escala AOFAS (pobre, aceptable, bueno y excelente).

INTRODUCTION: walking is a complex activity, requiring a strict balance, where the entire lower limb acts together to perform the movement and where the foot is the only part that acts on the ground. Therefore, any anatomical and biomechanical alteration of the foot has an impact on the ambulation. OBJECTIVE: to determine the degree of functional ­ radiological correlation in patients treated by the scarf osteotomy. MATERIAL AND METHODS: correlational and cross-sectional study. 78 patients diagnosed with hallux valgus were studied. Functional and radiological (AOFAS Scale) assessment was performed on all patients with hallux valgus operated by scarf osteotomy; the correlation between each patient's functional and radiological assessment was also established using the squared chi test. RESULTS: having obtained the critical value of Chi ­ squared ((X2c x 12,992), it was found that this is less than the value of the Chi ­ calculated square, both for the phalangeal metatarsus angle (X2 x 40.715) and the inter-metatarsal angle (X2 x 16,539); which means that the null hypothesis was not accepted (Functional results do not correlate with radiological results inversely proportional). CONCLUSION: a degree of reverse correlation between functional and radiological results was determined in patients treated with scarf osteotomy; α = 0.05; p = 0.95. ­ meaning that the greater the gradation of hallux valgus (mild, moderate and severe), the lower the AOFAS scale score (poor, acceptable, good and excellent).
