Contemporary Management of Axillo-subclavian Arterial Injuries Using Data from the AAST PROOVIT Registry
(Division of Cardiothoracic and Vascular Surgery and General Surgery, Örebro University Hospital, Sweden, 2021) Guntur, Grahya; DuBose, Joseph J.; Bee, Tiffany K.; Fabian, Timothy; Morrison, Jonathan; Skarupa, David J.; Inaba, Kenji; Kundi, Rishi; Scalea, Thomas; Feliciano, David V.; AAST PROOVIT Study Group; Surgery, School of Medicine
Background: Endovascular repair has emerged as a viable repair option for axillo-subclavian arterial injuries in select patients; however, further study of contemporary outcomes is warranted. Methods: The American Association for the Surgery of Trauma (AAST) PROspective Observational Vascular Injury Treatment (PROOVIT) registry was used to identify patients with axillo-subclavian arterial injuries from 2013 to 2019. Demographics and outcomes were compared between patients undergoing endovascular repair versus open repair. Results: 167 patients were identified, with intervention required in 107 (64.1%). Among these, 24 patients underwent open damage control surgery (primary amputation = 3, ligation = 17, temporary vascular shunt = 4). The remaining 83 patients (91.6% male; mean age 26.0 ± 16) underwent either endovascular repair (36, 43.4%) or open repair (47, 56.6%). Patients managed with definitive endovascular or open repair had similar demographics and presentation, with the only exception being that endovascular repair was more commonly employed for traumatic pseudoaneurysms (p = 0.004). Endovascular repair was associated with lower 24-hour transfusion requirements (p = 0.012), but otherwise the two groups were similar with regards to in-hospital outcomes. Conclusion: Endovascular repair is now employed in >40% of axillo-subclavian arterial injuries undergoing repair at initial operation and is associated with lower 24-hour transfusion requirements, but otherwise outcomes are comparable to open repair.
Diagnosis and Management of Esophageal Injuries: A Western Trauma Association Critical Decisions Algorithm
(Lippincott Williams & Wilkins, 2015-06) Biffl, Walter L.; Moore, Ernest E.; Feliciano, David V.; Albrecht, Roxie A.; Croce, Martin; Karmy-Jones, Riyad; Namias, Nicholas; Rowell, Susan; Schreiber, Martin; Shatz, David V.; Brasel, Karen; Department of Surgery, IU School of Medicine
ABSTRACT: This is a recommended management algorithm from the Western Trauma Association addressing the diagnostic evaluation and management of esophageal injuries in adult patients. Because there is a paucity of published prospective randomized clinical trials that have generated Class I data, the recommendations herein are based primarily on published observational studies and expert opinion of Western Trauma Association members. The algorithms and accompanying comments represent a safe and sensible approach that can be followed at most trauma centers. We recognize that there will be patient, personnel, institutional, and situational factors that may warrant or require deviation from the recommended algorithm. We encourage institutions to use this guideline to formulate their own local protocols. The algorithm contains letters at decision points; the corresponding paragraphs in the text elaborate on the thought process and cite pertinent literature. The annotated algorithm is intended to (a) serve as a quick bedside reference for clinicians; (b) foster more detailed patient care protocols that will allow for prospective data collection and analysis to identify best practices; and (c) generate research projects to answer specific questions concerning decision making in the management of adults with esophageal injuries.

(Elsevier, 2016-07) Valsangkar, Nakul P.; Kays, Joshua K.; Feliciano, David V.; Martin, Paul J.; Parett, Jordan S.; Joshi, Mugdha M.; Zimmers, Teresa A.; Koniaris, Leonidas G.; Department of Surgery, IU School of Medicine
Background A core objective of the Society of University Surgeons (SUS) is research focused: to “advance the art and science of surgery through original investigation.” This study sought to determine the current impact of the SUS on academic surgical productivity. Methods Individual faculty data for numbers of publications, citations, and National Institute of Health (NIH) funding history were collected for 4,015 surgical faculty at the top 55 NIH-funded departments of surgery using SCOPUS and the NIH Research Portfolio Online Reporting Tools. SUS membership was determined from membership registry data. Results Overall, 502 surgical faculty (12.5%) were SUS members with 92.7% holding positions of associate or full professor (versus 59% of nonmembers). Median publications (P) and citations (C) among SUS members were P: 112, C: 2,460 versus P: 29, C: 467 for nonmembers (P < .001). Academic productivity was considerably higher by rank for SUS members than for nonmembers: associate professors (P: 61 vs 36, C: 1,199 vs 591, P < .001) and full professors (P: 141 vs 81, C: 3,537 vs 1,856, P < .001). Among full professors, SUS members had much higher rates of NIH funding than did nonmembers (52.6% vs 26%, P < .05) and specifically for R01, P01, and U01 awards (37% vs 17.7%, P < .01). SUS members were 2 times more likely to serve in divisional leadership or chair positions (23.5% vs 10.2%, P < .05). Conclusion SUS society members are a highly productive academic group. These data support the premise that the SUS is meeting its research mission and identify its members as very academically productive contributors to research and scholarship in American surgery and medicine.
Increased Trauma Activation Is Not Equally Beneficial For All Elderly Trauma Patients
(Wolters Kluwer, 2018-05) Carr, Bryan W.; Hammer, Peter M.; Timsina, Lava; Rozycki, Grace; Feliciano, David V.; Coleman, Jamie J.; Surgery, School of Medicine
Background Physiologic changes in the elderly lead to higher morbidity and mortality after injury. Increasing level of trauma activation has been proposed to improve geriatric outcomes; but, the increased cost to the patient and stress to the hospital system are significant downsides. The purpose of this study was to identify the age at which an increase in activation status is beneficial. Methods A retrospective review of trauma patients ≥ 70 years old from October 1, 2011, to October 1, 2016 was performed. On October 1, 2013, a policy change increased the activation criteria to the highest level for patients ≥ 70 years of age with a significant mechanism of injury. Patients who presented prior to (PRE) were compared to those after the change (POST). Data collected included age, injury severity score (ISS), length of stay (LOS), complications and mortality. Primary outcome was mortality and secondary outcome was LOS. Multivariable regressions controlled for age, ISS, injury mechanism, and number of complications. Results 4341 patients met inclusion criteria, 1919 in PRE and 2422 in POST. Mean age was 80.4 and 81 years in PRE and POST groups respectively (p=0.0155). Mean ISS values were 11.6 and 12.4 (p<0.0001) for the PRE and POST groups. POST had more level 1 activations (696 vs. 220, p<0.0001). After controlling for age, ISS, mechanism of injury, and number of complications, mortality was significantly reduced in the POST group ≥ age 77 years (OR 0.53, 95% CI: 0.3 - 0.87), (Figure 1). Hospital LOS was significantly reduced in the POST group ≥ age 78 (regression coefficient -0.55, 95% CI: -1.09, -0.01) (Figure 2). Conclusions This study suggests geriatric trauma patients ≥ 77 years benefit from the highest level of trauma activation with shorter LOS and lower mortality. A focused approach to increasing activation level for elderly patients may decrease patient cost. Level of Evidence Level III Type of Study Economic/Decision
Pitfalls in the management of peripheral vascular injuries
(BMJ Publishing Group, 2017-08-28) Feliciano, David V.; Medicine, School of Medicine
Over the past 65+ years, most civilian peripheral vascular injuries have been managed by trauma surgeons with training or experience in vascular repair or ligation. This is appropriate as the in-hospital trauma team is immediately available, and there are often other injuries present in the victim. The pitfall to avoid during evaluation of the patient in the emergency center is a missed diagnosis. In the patient without 'hard' signs of a peripheral vascular injury, a careful history (bleeding), physical examination including measurement of ankle-brachial (ABI) or brachial-brachial index and liberal use of CT arteriography depending on an ABI <0.9 should essentially make the diagnosis if an arterial injury is present. At operation, one pitfall is to limit skin preparation and draping, thereby eliminating the option of removing the greater saphenous vein if needed as a conduit from either the groin or ankle of an uninjured lower extremity. Another pitfall is to make a full longitudinal incision directly over a large pulsatile hematoma. Rather, separate shorter longitudinal incisions should be made to obtain proximal and distal vascular control before entering the hematoma. The failure to recognize patients who should be managed initially with insertion of a temporary intraluminal shunt is a major pitfall as well. Not following time-proven and results-proven 'fine techniques' of operative repair is another major pitfall. Such techniques include the following: use of small angioaccess vascular clamps or silastic vessel loops; passage of proximal and distal Fogarty catheters; administration of regional or systemic heparin during complex repairs; an open anastomosis technique; and completion arteriography after a complex arterial repair in a lower extremity. Avoiding pitfalls should allow for success in peripheral vascular repair, particularly since most patients are young with non-diseased vessels
Reassessing the cardiac box: A comprehensive evaluation of the relationship between thoracic gunshot wounds and cardiac injury
(Lippincott, Williams, and Wilkins, 2017-04) Jhunjhunwala, Rashi; Mina, Michael J.; Roger, Elizabeth I.; Dente, Christopher J.; Heninger, Michael; Carr, Jacquelyn S.; Dougherty, Stacy D.; Gelbard, Rondi B.; Nicholas, Jeffrey M.; Wyrzykowski, Amy D.; Feliciano, David V.; Morse, Bryan C.; Department of Surgery, IU School of Medicine
Background: High energy missiles can cause cardiac injury regardless of entrance site. This study assesses the adequacy of the anatomic borders of the current “cardiac box” to predict cardiac injury. Methods: Retrospective autopsy review was performed to identify patients with penetrating torso gunshot wounds 2011-2013. Using a circumferential grid system around the thorax, logistic regression analysis was performed to detect differences in rates of cardiac injury from entrance/exit wounds in the “cardiac box” vs. the same for entrance/exit wounds outside the box. Analysis was repeated to identify regions to compare risk of cardiac injury between the current cardiac box and other regions of the thorax. Results: Over the study period, 263 patients (89% male, mean age = 34 years, median injuries/person = 2) sustained 735 wounds [80% gunshot wounds (GSWs], and 239 patients with 620 GSWs were identified for study. Of these, 95 (34%) injured the heart. Of the 257 GSWs entering the cardiac box, 31% caused cardiac injury while 21% GSWs outside the cardiac box (n = 67) penetrated the heart, suggesting that the current “cardiac box” is a poor predictor of cardiac injury relative to the thoracic non-"cardiac box" regions [Relative Risk (RR) 0.96; p=0.82]. The regions from the anterior to posterior midline of the left thorax provided the highest positive predictive value (41%) with high sensitivity (90%) while minimizing false positives making this region the most statistically significant discriminator of cardiac injury (RR 2.9; p=0.01). Conclusion: For GSWs, the current cardiac box is inadequate to discriminate whether a gunshot wound will cause a cardiac injury. As expected, entrance wounds nearest to the heart are the most likely to result in cardiac injury, but, from a clinical standpoint, it is best to think outside the “box” for GSWs to the thorax.
A Surgery Trainee’s Guide to Writing a Manuscript
(Elsevier, 2017-09) Liang, Tiffany W.; Feliciano, David V.; Koniaris, Leonidas G.; Department of Surgery, School of Medicine
Publishing clinical and research work for dissemination is a critical part of the academic process. Learning how to write an effective manuscript should be a goal for medical students and residents who hope to participate in publishing. While there are a number of existing texts that address how to write a manuscript, there are fewer guides that are specifically targeted towards surgery trainees. This review aims to direct and hopefully encourage surgery trainees to successfully navigate the process of converting ideas into a publication that ultimately helps understanding and improves the care of patients.
To Sleep, Perchance to Dream: Acute and Chronic Sleep Deprivation in Acute Care Surgeons
(Elsevier, 2019) Coleman, Jamie J.; Robinson, Caitlin K.; Zarzaur, Ben L.; Timsina, Lava; Rozycki, Grace S.; Feliciano, David V.; Surgery, School of Medicine
Background Acute and chronic sleep deprivation are significantly associated with depressive symptoms and felt to be contributors to the development of burnout. In-house call (IHC) inherently includes frequent periods of disrupted sleep and is common amongst acute care surgeons (ACS). The relationship between IHC and sleep deprivation (SD) amongst ACS has not been previously studied. The goal of this study was to determine prevalence and patterns of SD in ACS. Study Design: A prospective study of ACS with IHC responsibilities from two Level I trauma centers was performed. Participants wore a sleep tracking device continuously over a 3-month period. Data collected included age, gender, schedule of IHC, hours and pattern of each sleep stage (light, slow wave (SWS), and REM), and total hours of sleep. Sleep patterns were analyzed for each night excluding IHC and categorized as normal (N), acute sleep deprivation (ASD), or chronic sleep deprivation (CSD). Results 1421 nights were recorded amongst 17 ACS. (35.3% female; ages 37-65, mean 45.5 years). Excluding IHC, average amount of sleep was 6.54 hours with 64.8% of sleep patterns categorized as ASD or CSD. Average amount of sleep was significantly higher on post-call day 1 (6.96 hours, p=0.0016), but decreased significantly on post-call day 2 (6.33 hours, p=0.0006). Sleep patterns with ASD and CSD peaked on post-call day 2, and returned to baseline on post-call day 3 (p=0.046). Conclusion Sleep patterns consistent with ASD and CSD are common amongst ACS and worsen on post-call day 2. Baseline sleep patterns were not recovered until post-call day 3. Future study is needed to identify factors which impact physiologic recovery after IHC and further elucidate the relationship between SD and burnout.
