Starting a Vascular Surgery Fellowship at a Rural Healthcare Center.

INTRODUCTION: In the United States, there is an anticipated critical shortage of vascular surgeons in the coming decades. The shortage is expected to be particularly pronounced in rural areas. Our institution serves a rural and underserved population in which the incidence and prevalence of cardiovascular disease continues to rise. Our institution maintains a general surgery residency and has all the required Accreditation Council for Graduate Medical Education (ACGME) rotations and educational infrastructure to support a vascular surgery fellowship. This study aims to analyze the vascular caseload at our institution to determine if we and other institutions with similar surgical volumes can support the creation of a 2-year vascular fellowship. METHODS: A single-site retrospective review of the number and type of vascular cases conducted at our institution between July 2016 and June 2021 was performed. The procedures were grouped into the following ACGME-defined categories: abdominal, cerebrovascular, complex, endovascular aneurysm repair, endovascular diagnostic or therapeutic, and peripheral. The total number and annual average for each category was obtained. Using the annual average, a 2-year estimate was calculated and compared to the ACGME minimum for each category. Our 2-year estimate was then compared to the national average for graduating vascular surgery fellows in order to generate a z-score for each category. RESULTS: In the specified period, 6100 total surgical procedures were performed by three vascular surgeons at our institution. Two thousand five hundred and seventy-eight of the 6100 procedures met at least one of the ACGME-defined category requirements. Our center greatly exceeded the requirements for each category except for abdominal. This is consistent with trends observed in most centers across the nation, which are seeing a decline in open repairs across all categories, especially in open abdominal repairs. Our center's vascular case volume shows no significant difference the national average in each ACGME category (P ≥ 0.05 for all). CONCLUSIONS: Despite our center's large vascular caseload and need for more vascular providers, there were not enough open abdominal cases performed to support the training of a vascular fellow. Given the continued decline in open aortic volume across the country, we anticipate that rural centers similar to our own will have difficulty establishing programs to train and recruit vascular surgeons. Flexibility in the abdominal category requirement or creation of open aortic fellowships may be necessary for smaller rural centers to train vascular surgeons and meet the future needs of the specialty.

Blunt pancreatic trauma: A Western Trauma Association critical decisions algorithm.

BACKGROUND: The Western Trauma Association (WTA) has undertaken publication of best practice clinical practice guidelines on multiple trauma topics. These guidelines are based on scientific evidence, case reports, and best practices per expert opinion. Some of the topics covered by this consensus group do not have the ability to have randomized controlled studies completed because of complexity, ethical issues, financial considerations, or scarcity of experience and cases. Blunt pancreatic trauma falls under one of these clinically complex and rare scenarios. This algorithm is the result of an extensive literature review and input from the WTA membership and WTA Algorithm Committee members. METHODS: Multiple evidence-based guideline reviews, case reports, and expert opinion were compiled and reviewed. RESULTS: The algorithm is attached with detailed explanation of each step, supported by data if available. CONCLUSION: Blunt pancreatic trauma is rare and presents many treatment challenges.

BACKGROUND: The Western Trauma Association has undertaken publication of best practice clinical practice guidelines on multiple trauma topics. These guidelines are based on scientific evidence, case reports, and best practices per expert opinion. Some of the topics covered by this consensus group do not have the ability to have randomized controlled studies completed because of complexity, ethical issues, financial considerations or scarcity of experience. Care of the pregnant trauma patient is one of these clinically complex situations that is based on physiologic data, standard trauma care, trauma care experience, and outcomes. METHODS: Review of multiple evidence- based guidelines, case reports, and expert opinion were compiled and reviewed. RESULTS: The algorithm is attached with detailed explanation of each step, supported by data if available. CONCLUSION: Resuscitative and trauma care of the mother is the utmost priority. STUDY TYPE: Algorithm, expert opinion, consensus. LEVEL OF EVIDENCE: Diagnostic Tests/Criteria; Level III.

Real-time infection prediction with wearable physiological monitoring and AI to aid military workforce readiness during COVID-19.

Infectious threats, like the COVID-19 pandemic, hinder maintenance of a productive and healthy workforce. If subtle physiological changes precede overt illness, then proactive isolation and testing can reduce labor force impacts. This study hypothesized that an early infection warning service based on wearable physiological monitoring and predictive models created with machine learning could be developed and deployed. We developed a prototype tool, first deployed June 23, 2020, that delivered continuously updated scores of infection risk for SARS-CoV-2 through April 8, 2021. Data were acquired from 9381 United States Department of Defense (US DoD) personnel wearing Garmin and Oura devices, totaling 599,174 user-days of service and 201 million hours of data. There were 491 COVID-19 positive cases. A predictive algorithm identified infection before diagnostic testing with an AUC of 0.82. Barriers to implementation included adequate data capture (at least 48% data was needed) and delays in data transmission. We observe increased risk scores as early as 6 days prior to diagnostic testing (2.3 days average). This study showed feasibility of a real-time risk prediction score to minimize workforce impacts of infection.

Evaluation and management of traumatic pneumothorax: A Western Trauma Association critical decisions algorithm.

ABSTRACT: This is a recommended algorithm of the Western Trauma Association for the management of a traumatic pneumothorax. The current algorithm and recommendations are based on available published prospective cohort, observational, and retrospective studies and the expert opinion of the Western Trauma Association members. The algorithm and accompanying text represents a safe and reasonable approach to this common problem. We recognize that there may be variability in decision making, local resources, institutional consensus, and patient-specific factors that may require deviation from the algorithm presented. This annotated algorithm is meant to serve as a basis from which protocols at individual institutions can be developed or serve as a quick bedside reference for clinicians. LEVEL OF EVIDENCE: Consensus algorithm from the Western Trauma Association, Level V.

Association Between American Board of Surgery Initial Certification and Risk of Receiving Severe Disciplinary Actions Against Medical Licenses.

Importance: Board certification is used as a marker of surgeon quality and professionalism. Although some research has linked certification in surgery to outcomes, more research is needed. Objective: To measure associations between surgeons obtaining American Board of Surgery (ABS) certification and examination performance with receiving future severe disciplinary actions against their medical licenses. Design, Setting, and Participants: Retrospective analysis of severe license action rates for surgeons who attempted ABS certification based on certification status and examination performance. Surgeons who attempted to become certified were classified as certified or failing to obtain certification. Additionally, groups were further categorized based on whether the surgeon had to repeat examinations and whether they ultimately passed. The study included surgeons who initially attempted certification between 1976 and 2017 (n = 44 290). Severe license actions from 1976 to 2018 were obtained from the Federation of State Medical Boards, and certification data were obtained from the ABS database. Data were analyzed between 1978 and 2008. Main Outcomes and Measures: Severe license action rates were analyzed across certified surgeons and those failing to obtain certification, as well as across examination performance groups. Results: The final dataset included 36 197 men (81.7%) and 8093 women (18.3%). The incidence of severe license actions was significantly greater for surgeons who attempted and failed to obtain certification (incidence rate per 1000 person-years = 2.49; 95% CI, 2.13-2.85) than surgeons who were certified (incidence rate per 1000 person years = 0.77; 95% CI, 0.71-0.83). Adjusting for sex and international medical graduate status, the risk of receiving a severe license action across time was also significantly greater for surgeons who failed to obtain certification. Surgeons who progressed further in the certification examination sequence and had fewer repeated examinations had a lower incidence and less risk over time of receiving severe license actions. Conclusions and Relevance: Obtaining board certification was associated with a lower rate of receiving severe license actions from a state medical board. Passing examinations in the certification examination process on the first attempt was also associated with lower severe license action rates. This study provides supporting evidence that board certification is 1 marker of surgeon quality and professionalism.

Gunshot wounds and blast injuries to the face are associated with significant morbidity and mortality: results of an 11-year multi-institutional study of 720 patients.

BACKGROUND: Gunshot wounds and blast injuries to the face (GSWBIFs) produce complex wounds requiring management by multiple surgical specialties. Previous work is limited to single institution reports with little information on processes of care or outcome. We sought to determine those factors associated with hospital complications and mortality. METHODS: We performed an 11-year multicenter retrospective cohort analysis of patients sustaining GSWBIF. The face, defined as the area anterior to the external auditory meatuses from the top of the forehead to the chin, was categorized into three zones: I, the chin to the base of the nose; II, the base of the nose to the eyebrows; III, above the brows. We analyzed the effect of multiple factors on outcome. RESULTS: From January 1, 2000, to December 31, 2010, we treated 720 patients with GSWBIF (539 males, 75%), with a median age of 29 years. The wounding agent was handgun in 41%, explosive (shotgun and blast) in 20%, rifle in 6%, and unknown in 33%. Prehospital or resuscitative phase airway was required in 236 patients (33%). Definitive care was rendered by multiple specialties in 271 patients (38%). Overall, 185 patients died (26%), 146 (79%) within 48 hours. Of the 481 patients hospitalized greater than 48 hours, 184 had at least one complication (38%). Factors significantly associated with any of a total of 207 complications were total number of operations (p < 0.001), Revised Trauma Score (RTS, p < 0.001), and head Abbreviated Injury Scale (AIS) score (p < 0.05). Factors significantly associated with mortality were RTS (p < 0.001), head AIS score (p < 0.001), total number of operations (p < 0.001), and age (p < 0.05). An injury located in Zone III was independently associated with mortality (p < 0.001). CONCLUSION: GSWBIFs have high mortality and are associated with significant morbidity. The multispecialty involvement required for definitive care necessitates triage to a trauma center and underscores the need for an organized approach and the development of effective guidelines. LEVEL OF EVIDENCE: Therapeutic/care management, level III.

Transcranial Doppler investigation of hemodynamic alterations associated with blunt cervical vascular injuries in trauma patients.

OBJECTIVES: Blunt cervical vascular injuries, often missed with current screening methods, have substantial morbidity and mortality, and there is a need for improved screening. Elucidation of cerebral hemodynamic alterations may facilitate serial bedside monitoring and improved management. Thus, the objective of this study was to define cerebral flow alterations associated with single blunt cervical vascular injuries using transcranial Doppler sonography and subsequent Doppler waveform analyses in a trauma population. METHODS: In this prospective pilot study, patients with suspected blunt cervical vascular injuries had diagnoses by computed tomographic angiography and were examined using transcranial Doppler sonography to define cerebral hemodynamics. Multiple vessel injuries were excluded for this analysis, as the focus was to identify hemodynamic alterations from isolated injuries. The inverse damping factor characterized altered extracranial flow patterns; middle cerebral artery flow velocities, the pulsatility index, and their asymmetries characterized altered intracranial flow patterns. RESULTS: Twenty-three trauma patients were evaluated: 4 with single internal carotid artery injuries, 5 with single vertebral artery injuries, and 14 without blunt cervical vascular injuries. All internal carotid artery injuries showed a reduced inverse damping factor in the internal carotid artery and dampened ipsilateral mean flow and peak systolic velocities in the middle cerebral artery. Vertebral artery injuries produced asymmetry of a similar magnitude in the middle cerebral artery mean flow velocity with end-diastolic velocity alterations. CONCLUSIONS: These data indicate that extracranial and intracranial hemodynamic alterations occur with internal carotid artery and vertebral artery blunt cervical vascular injuries and can be quantified in the acute injury phase by transcranial Doppler indices. Further study is required to elucidate cerebral flow changes resulting from a single blunt cervical vascular injury, which may guide future management to preserve cerebral perfusion after trauma.

A novel decision tree approach based on transcranial Doppler sonography to screen for blunt cervical vascular injuries.

OBJECTIVES: Early detection and treatment of blunt cervical vascular injuries prevent adverse neurologic sequelae. Current screening criteria can miss up to 22% of these injuries. The study objective was to investigate bedside transcranial Doppler sonography for detecting blunt cervical vascular injuries in trauma patients using a novel decision tree approach. METHODS: This prospective pilot study was conducted at a level I trauma center. Patients undergoing computed tomographic angiography for suspected blunt cervical vascular injuries were studied with transcranial Doppler sonography. Extracranial and intracranial vasculatures were examined with a portable power M-mode transcranial Doppler unit. The middle cerebral artery mean flow velocity, pulsatility index, and their asymmetries were used to quantify flow patterns and develop an injury decision tree screening protocol. Student t tests validated associations between injuries and transcranial Doppler predictive measures. RESULTS: We evaluated 27 trauma patients with 13 injuries. Single vertebral artery injuries were most common (38.5%), followed by single internal carotid artery injuries (30%). Compared to patients without injuries, mean flow velocity asymmetry was higher for single internal carotid artery (P = .003) and single vertebral artery (P = .004) injuries. Similarly, pulsatility index asymmetry was higher in single internal carotid artery (P = .015) and single vertebral artery (P = .042) injuries, whereas the lowest pulsatility index was elevated for bilateral vertebral artery injuries (P = .006). The decision tree yielded 92% specificity, 93% sensitivity, and 93% correct classifications. CONCLUSIONS: In this pilot feasibility study, transcranial Doppler measures were significantly associated with the blunt cervical vascular injury status, suggesting that transcranial Doppler sonography might be a viable bedside screening tool for trauma. Patient-specific hemodynamic information from transcranial Doppler assessment has the potential to alter patient care pathways to improve outcomes.
