Catastrophic bleeding is a feared complication of robotic abdominal procedures that involve dissection in close proximity to major vessels. In the event of uncontrollable hemorrhage, standard practice involves emergency undocking with conversion to laparotomy. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a rapid and life-saving technique gaining acceptance in the trauma setting for the management of catastrophic hemorrhage. The purpose of this study was to evaluate feasibility of REBOA for emergency hemostasis during robotic surgery. The surgical robot was docked to a REBOA mannequin to simulate an upper abdominal surgery. A femoral arterial line was placed in the mannequin. Supplies needed for REBOA insertion were opened and arranged on the surgical back table. The surgeon was seated at the console with an assistant scrubbed. A catastrophic vascular injury was announced. The time it took the surgeon to achieve aortic occlusion by the REBOA was recorded. Four surgeons participated and performed three timed trials each. Each surgeon, irrespective of experience with REBOA or years in surgical practice, was able to obtain aortic occlusion in less than 2 min. The mean time to aortic occlusion for all surgeons was 111 s. No manipulation of the robotic arms was required to perform the procedure. Aortic occlusion was achieved rapidly with REBOA. Ability to achieve prompt aortic control was not associated with surgical experience or prior familiarity with the REBOA device. Prophylactic femoral access and preparation of supplies facilitates prompt placement of the occlusion balloon. REBOA should be considered as a viable alternative to open laparotomy for temporary hemorrhage control during robotic surgery.

Background Pedestrians struck by automobiles are at significant risk for mortality. Multiple environmental features have been developed to promote separation of pedestrians from motor vehicles. However, data on the effectiveness of these pedestrian traffic safety features are lacking. The purpose of this study was to use Google Street View to assess the locations of pedestrian-automobile injury and evaluate the relationship of environmental pedestrian safety features to pedestrian involved crashes. Methods Our trauma registry was queried for pedestrians injured by automobile collision. Google Street View was used to identify safety features present at each injury location. A composite safety score was created by summing the number of safety features at each crash location. A logistic regression model was performed to evaluate the impact of safety features on mortality. Results Our sample consisted of 631 patients (69.3% male) with an average age of 40.4 ± 17.0 years and median Injury Severity Score of 10 (5-22). A multivariate logistic regression revealed safety score (range, 0-6) significantly predicted mortality with each one-unit increment associated with a 27.8% decrease in risk of mortality. Conclusion Increasing number of safety features as represented in a composite score may decrease risk of pedestrian mortality. Google Street View appears to be a viable tool to study the presence and effectiveness of these pedestrian safety features. Level of evidence Epidemiological, level III.

Stricturing of the biliary-enteric anastomosis is a known complication of emergent pancreaticoduodenectomy (PD) performed for trauma. Percutaneous techniques have become the first-line option for the management of these strictures. In cases where percutaneous intervention fails, surgical revision of the biliary enteric anastomosis is necessary. We present two cases of young males with penetrating injuries to the pancreatic head managed with PD and subsequently developed post-operative biliary strictures. The biliary stricture was managed successfully with percutaneous intervention for one of the patients. The other patient required surgical revision of the biliary anastomosis. Pancreaticoduodenectomy is typically performed in patients with malignant or benign biliary obstruction with associated ductal dilatation. In the setting of trauma, the bile duct is typically non-dilated, creating greater susceptibility for anastomotic stricture. Although such strictures may be amenable to percutaneous cholangioplasty, strictures involving distal anastomoses may require operative revision. Thus, we suggest creating the more proximal hepaticojejunostomy during the initial operation, as this may benefit the success of percutaneous management should a stricture develop. Operative revision is the definitive management of post-PD biliary stricture.

BACKGROUND Although physician-patient communication and health literacy (HL) have been studied in diverse patient groups, there has been little focus on trauma patients. A quality improvement project was undertaken at our Level I trauma center to improve patient perception of physician-patient communication, with consideration of the effect of HL. We report the first phase of this project, namely the reference level of satisfaction with physician-patient communication as measured by levels of interpersonal care among patients at an urban Level I trauma center. METHODS Level I trauma center patients were interviewed during hospitalization (August 2016 to January 2017). Short Assessment of Health Literacy tool was used to stratify subjects by deficient versus adequate HL. Interpersonal Processes of Care survey was administered to assess perception of physician-patient communication. This survey allowed patients to rate physician-patient interaction across six domains: "clarity," "elicited concerns," "explained results," "worked together (on decision making)," "compassion and respect," and "lack of discrimination by race/ethnicity." Each is scored on a five-point scale. Frequencies of "top-box" (5/5) scores were compared for significance (p < 0.05) between HL-deficient and HL-adequate patients. RESULTS One hundred ninety-nine patients participated. Average age was 42 years, 33% female. Forty-nine (25%) patients had deficient HL. The majority of patients in both groups rated communication below 5/5 across all domains except "compassion and respect" and "lack of discrimination by race/ethnicity." Health literacy-deficient patients were consistently less likely to give physicians top-box scores, most notably in the "elicited concerns" domain (35% vs. 54%, p = 0.012). CONCLUSION Health literacy-deficient patients appear relatively less satisfied with physician communication, particularly with respect to perceiving that their concerns are being heard. Overall, however, the majority of patients in both groups were unlikely to score physician communication in the "top box." Efforts to improve physician-trauma patient communication are warranted, with attention directed toward meeting the needs of HL-deficient patients.

Introduction Patient compliance and outcomes have been shown to be influenced by the quality of the doctor-patient relationship. In addition, the effect of physician attire on the patient's perception of the physician has been long appreciated. Data shows that professional attire is preferred by patients. Whereas treating physicians are the backbone of patient management, medical students are often a patient's first encounter in a teaching clinic. Patient perception of the student may impact their rating of the attending physician. Despite this, medical students are often dressed wearing scrubs in surgery clinic. The purpose of this study was to determine if patient perception of medical students would be affected by the students’ attire. Methods A 7-item, validated professionalism scale was used to survey surgery clinic patients whose initial examinations were performed by a medical student. Students were blinded and randomly assigned to wear professional attire versus scrubs. Patients’ responses of ‘strongly agree’ were compared to lower ratings for each item. Results One hundred twenty-three patients completed our survey, 63 (51.2%) wearing scrubs and 60 (48.8%) in professional attire. The average age was 49.7 ± 15.8 years. In the professional attire group, there was no significant association for any of the 7 items. However, in the scrubs group, all 7 items were significant such that a higher proportion of patients under the age of 60 rated medical students wearing scrubs higher than did patients aged 60 and above. Conclusion Students in scrubs were perceived to be less knowledgeable, competent, and professional by older patients. In contrast, younger patients seemed unaffected by the dress of medical students in clinic. Older patients may judge the medical community's growing acceptance of more casual attire in the workplace as less professional, potentially affecting patient satisfaction. Surgical educators should require a standard of professional attire for students in clinic.

Background The clinical pulmonary infection score (CPIS) and bronchoalveolar lavage (BAL) are 2 tools that have been validated to diagnose pneumonia in critically ill patients. However, the role of the CPIS in diagnosing trauma-associated pneumonia (TAP) remains in question. Methods This prospective observational study included all trauma patients who were ventilated for longer than 48 hours from September 2008 to September 2009. The CPIS and quantitative culture results from the BAL were collected and used to define pneumonia. Results A total of 162 patients were identified. In all, 58 (35.8%) and 104 (64.2%) had a CPIS greater than 5 and a CPIS of 5 or less, respectively. There were 95 (58.6%) patients who had a BAL completed regardless of CPIS. There were 65 patients who met the bacteriologic definition of pneumonia (≥104 colonies/mL), for an overall TAP incidence of 40.1%. Conclusions The CPIS is unreliable as a clinical tool to predict a positive BAL at 104 or 105 or higher threshold. Therefore, BAL should be used for the diagnosis of TAP based on clinical rationale and not the CPIS.
