The Effect of Area Social Deprivation on Health Behavior and Health Care Utilization in an Adult Trauma Population.

Social determinants of health may mediate health disparities, but these variables are not routinely measured in clinical practice. This is a retrospective, single-institution study that evaluates the effect of area deprivation on outcomes after trauma admission. Adult trauma patients 18 years and older were eligible. Patients were stratified into high-area (HSD) or low-area (LSD) social deprivation cohorts using zip code of residence. Regression modeling was used to explain the association between HSD, sociodemographic characteristics, and clinical outcomes. Patients who resided in HSD areas made up 29.5% of the study population, were more likely to be younger, male, and identify as a non-White race. Patients in the HSD cohort were also less likely to be admitted to the ICU (OR 0.84, CI 0.71-0.98) and discharged with additional services (OR 0.73, CI 0.57-0.94). We found that independently, area social deprivation affects trauma outcomes and the resources a patient is provided after discharge.

Laparoscopic-Assisted Transgastric Endoscopic Retrograde Cholangiopancreatography With Placement of a Biliary Stent to Treat Traumatic Intrahepatic Bile Duct Disruption in a Patient With Roux-en-Y Gastric Bypass.

Hepatic injuries are common following blunt trauma and while frequently managed expectantly, biliary injury as a result of the trauma requires a high index of suspicion, a focused workup, and likely interventional treatment. A 44-year-old female with a history of Roux-en-Y gastric bypass presented after a ground level fall and was initially discharged home but represented with worsening abdominal pain and elevated liver enzymes. She was found to have a segment 5/6 biliary injury requiring laparoscopic-assisted transgastric endoscopic retrograde cholangiopancreatography with common bile duct stent placement. This case represents the difficulty of diagnosing biliary injuries following blunt trauma, and the need for advanced endoscopic interventions for treatment in patients with atypical anatomy.

Acute Traumatic Spinal Cord Injury: Implementation of a Multidisciplinary Care Pathway.

BACKGROUND: Management of acute traumatic spinal cord injuries is complex, and patients are at risk for severe complications while inpatient. Performance review revealed opportunities for improvement in the care of patients with acute traumatic spinal cord injury at our institution. OBJECTIVE: To compare mortality, failure-to-rescue, and health care utilization of patients with acute traumatic spinal cord injury after implementation of a revised multidisciplinary care pathway. METHODS: Using a pre- and post-between-subjects study design, a retrospective cross-sectional analysis of consecutive patients admitted to our Level I trauma center with acute traumatic spinal cord injury was performed. An updated care pathway for all patients who presented with acute traumatic spinal cord injury was implemented in July 2020. This pathway includes a revised order set in the electronic medical record, distribution of a "best practice" guide to inpatient providers, a formal twice-daily respiratory evaluation, and weekly clinical nurse specialist-led patient rounds. RESULTS: One hundred and eight patients were included in analysis (prepathway: n = 52, postpathway: n = 56). Total mean hospital length of stay was 15.2 (14.0) and 21.5 (24.8) days for the pre- and postpathway groups. Eleven patients (21%) compared with six patients (11%) died, and failure-to-rescue occurred in six patients (60%) compared with zero patient in the pre- and postpathway groups, respectively. In addition, 10 (20%) postpathway patients were discharged to home compared with one (2%) in the prepathway group. DISCUSSION: Following implementation of the updated acute traumatic spinal cord injury pathway, overall inpatient mortality decreased, and fewer patients died after experiencing a complication. Results highlight the need for continued review of care practices and multidisciplinary review in quality improvement initiatives.

Low initial in-hospital end-tidal carbon dioxide predicts poor patient outcomes and is a useful trauma bay adjunct.

INTRODUCTION: Appropriate triage of the trauma patient is critical. Low end-tidal carbon dioxide (ETCO2) is associated with mortality and hemorrhagic shock in trauma, but the relationship between low ETCO2 and important clinical variables is not known. This study investigates the association of initial in-hospital ETCO2 and patient outcomes, as well as the utility of ETCO2 as a predictive aid for blood transfusion. METHODS: Adult patients who presented to a Level One trauma center from 2019 to 2020 were eligible. Trauma bay ETCO2 measured by side-stream capnography was prospectively obtained for all trauma activations at time of initial evaluation. Using the Liu method of cut point estimation, patients were stratified as having low (≤29.5 mmHg) or normal ETCO2 (>29.5 mmHg). Multivariable regression was used to estimate the association of low ETCO2 with patient outcomes. RESULTS: A total of 955 patients underwent initial in-hospital ETCO2 measurement. Median time from arrival to ETCO2 measurement was 4 min. Among admitted patients (N = 493), 48.9% had low ETCO2. Compared to patients with normal ETCO2, those with low ETCO2 were older (median age 53 vs 46, p = 0.01) and more likely to have the highest trauma activation (27.4% vs 19.8%, p = 0.048). There was no difference in head injury. After adjustment, patients with low ETCO2 had greater odds of blood transfusion (OR 4.65, 95%CI 2.0-10.7), mortality (OR 5.10, 95%CI 1.1-24.9), inferior disposition (OR 1.64, 95%CI 1.1-2.6), and complications (OR 3.35, 95%CI 1.5-7.4). ETCO2 was more predictive of early blood transfusion than Shock Index (area under ROC = 67.6% vs 58.2%). CONCLUSIONS: Low trauma bay ETCO2 remains significantly associated with inferior clinical outcomes after adjustment. In comparison to other triage tools, low ETCO2 values may be more predictive of the need for blood transfusion. Further studies are needed to evaluate the role of ETCO2 as a decision making tool for early trauma management.

Post-Mortem CT Delivers Fast and Accurate Injury Identification in Trauma Patients.

BACKGROUND: Accurate and timely injury identification is critical but difficult to achieve in trauma patients who die shortly after arrival to the hospital. Autopsy has historically been used to detect injuries, but few undergo formal autopsy. This study investigates the utility of post-mortem computed tomography (PMCT) for injury identification in a diverse trauma population. METHODS: Cross-sectional study of adult trauma patients who died within 24 hours of arrival to a Level I trauma center were included. Among patients with PMCT, injury severity score (ISS) and number of injuries (NOI) were calculated either from physical exam alone (pre-PMCT) or exam and imaging (post-PMCT). ISS and NOI before and after PMCT were compared. A cause of death analysis was performed for patients who underwent comprehensive (ie, head, neck, and torso) PMCT. Non-parametric repeated measures tests were used, as appropriate. RESULTS: 7.3% (N = 28) of patients received PMCT. Compared to pre-PMCT, median ISS (21 vs 3.5) and NOI (5 vs 2) were greater post-PMCT (P < .001, respectively). Autopsy rate was 13.2% overall; 82.5% of autopsies were due to a penetrating mechanism, and median time to autopsy reporting was 38.5 days. Among 17 patients who received comprehensive PMCT, 64.7% had a single cause of death identified, and the remaining were classified as either multiple potential contributors or unknown. DISCUSSION: PMCT is a readily available method to identify injuries in trauma patients who expire shortly upon presentation. Given the low autopsy rate for blunt trauma and delay in reporting, PMCT is an important adjunct for trauma providers.

Applying Evidence-based Principles to Guide Emergency Surgery in Older Adults.

Although outcomes for older adults undergoing elective surgery are generally comparable to younger patients, outcomes associated with emergency surgery are poor. These adverse outcomes are in part because of the physiologic changes associated with aging, increased odds of comorbidities in older adults, and a lower probability of presenting with classic "red flag" physical examination findings. Existing evidence-based perioperative best practice guidelines perform better for elective compared with emergency surgery; so, decision making for older adults undergoing emergency surgery can be challenging for surgeons and other clinicians and may rely on subjective experience. To aid surgical decision making, clinicians should assess premorbid functional status, evaluate for the presence of geriatric syndromes, and consider social determinants of health. Documentation of care preferences and a surrogate decision maker are critical. In discussing the risks and benefits of surgery, patient-centered narrative formats with inclusion of geriatric-specific outcomes are important. Use of risk calculators can be meaningful, although limitations exist. After surgery, daily evaluation for common postoperative complications should be considered, as well as early discharge planning and palliative care consultation, if appropriate. The role of the geriatrician in emergency surgery for older adults may vary based on the acuity of patient presentation, but perioperative consultation and comanagement are strongly recommended to optimize care delivery and patient outcomes.

Healthcare Disparity Education for Surgical Residents: Progress Made, More Needed.

BACKGROUND: Healthcare disparities are an important determinant of patient outcomes yet are not standardized within surgical resident education. This study aimed to determine the prevalence and design of current healthcare disparities curricula for surgical residents and included a resident-based needs assessment at a single institution. STUDY DESIGN: A national survey evaluating the presence and design of healthcare disparities curricula was distributed to general surgery program directors via the Association of Program Directors in Surgery Listserv. A related survey was administered to all general surgery residents at a single academic institution. RESULTS: One hundred forty-six program directors completed the survey, with 68 (47%) reporting an active curriculum. The most frequently taught topic is regarding patient race as a healthcare disparity, found in 63 (93%) of existing curricula. Fifty-two (76%) of the curricula were implemented within the last 3 years. Of the 78 (53%) programs without a curriculum, 8 (10%) program directors stated that their program would not benefit from one. Thirty-four (45%) of the programs without a curriculum cited institutional support and time as the most common barriers to implementation. Of the 23 residents who completed the survey, 100% desired learning practical knowledge regarding healthcare disparities relating to how race and socioeconomic status affect the clinical outcomes of surgical patients. CONCLUSIONS: Less than half of general surgery training programs have implemented healthcare disparities curricula. Resident preferences for the format and content of curricula may help inform program leaders and lead to comprehensive national standards.

Operative Management Considerations in a Patient With Multiple Occult Penetrating Cardiac Injuries.

Penetrating cardiac injury remains one of the deadliest traumatic injuries. Early identification and definitive operative management are critical tenets for patient survival; however, variable clinical presentations can obscure the diagnosis. Here, we present the case of a 58-year-old obese man who presented to an urban level 1 trauma center with multiple stab wounds to the epigastrium and lateral left chest in the axillary line with an unknown weapon. The patient was taken emergently to the operating room for exploratory laparotomy, median sternotomy, and attempted repair of multiple full-thickness lacerations of the right ventricle and left and right atrium. This case demonstrates several instructive points. First, a high index of suspicion for penetrating cardiac injury is needed, especially during triage of multiple injuries. Second, careful release of cardiac tamponade is critical. Finally, there are several indications for cardiopulmonary bypass, which include multichambered injuries, uncontrollable hemorrhage, and concern for intracardiac injury.

A Novel Educational Tool to Improve Medical Student Knowledge Acquisition During Surgical Rotations.

BACKGROUND: The addition of a novel education tool helps students improve understanding of general surgery topics. However, the effect of the new tool on objective exam performance is unknown. MATERIALS: A 10-item card of high-yield general surgery topics was implemented in the third-year surgery clerkship. Students reviewed these topics with general surgery residents. Scores from the National Board of Medical Examiners (NBME) surgery subject exam and Step 2 Clinical Knowledge (CK) board exam were compared among students who completed the Ask-a-Resident Topic card to a control group. RESULTS: Students who participated in the curriculum demonstrated significantly better scores on the NBME Surgery exam, t (236) = -2.56, P = .006. There was not a significant effect of the curriculum on Step 2 CK scores, although students who participated in the curriculum (M = 250.7, SD = 13.4) achieved higher scores than the control group (M = 247.8, SD = 14.2). DISCUSSION: The novel curriculum may improve objective student performance on standardized surgery exams.

The prevalence of pancreatic incidentalomas in patients undergoing surveillance for abdominal aortic aneurysms.

BACKGROUND: Serial imaging in patients with aortic aneurysms may identify non-vascular disease. However, the prevalence and clinical history of pancreatic incidentalomas in this population is unknown. METHODS: Retrospective cross-sectional study of adults who underwent computed tomography angiography (CTA) surveillance imaging for abdominal or thoracoabdominal aortic aneurysm at a single academic institution between 2015 and 2020. Descriptive statistics were used for patients with pancreatic lesions. RESULTS: Of 249 patients, 18 (7.2 %) had a pancreatic incidentaloma. Compared to patients without a lesion, those with a lesion were more likely female (50.0 % vs 24.2 %, p = 0.02) and less likely a smoker (72.2 % vs 90.0 %, p = 0.02). 3 patients with pancreatic lesions underwent intervention, and 1 patient received additional imaging. 2 patients had a surgical oncology referral. CONCLUSIONS: Pancreatic incidentalomas are common in patients with aortic aneurysm, but lesion characteristics and management vary. Results suggest that a multi-disciplinary approach, thorough documentation, and referral to pancreatic specialists may be warranted.

"Low initial pre-hospital end-tidal carbon dioxide predicts inferior clinical outcomes in trauma patients".

INTRODUCTION: Current guidelines continue to lead to under- and over-triage of injured patients in the pre-hospital setting. End-tidal carbon dioxide (ETCO2) has been correlated with mortality and hemorrhagic shock in trauma patients. This study examines the correlation between ETCO2 and in-hospital outcomes among non-intubated patients in the pre-hospital setting. METHODS: We retrospectively studied a cohort of non-intubated adult trauma patients with initial pre-hospital side-stream capnography-obtained ETCO2 presenting via ground transport from a single North Carolina EMS agency to a level one trauma center from January 2018 to December 2018. Using the Liu method, the optimal threshold for low ETCO2 was ≤ 28.5 mmHg. RESULTS: Initial pre-hospital ETCO2 was recorded for 324 (22.0%) of 1473 patients with EMS data. Patients with low ETCO2 (N = 98, 30.3% of cohort) were older (median 58y vs 45y), but mechanisms of injury and scene vital signs were similar (p>0.05) between low and normal/high ETCO2 cohorts. Median injury severity score (ISS) did not differ significantly between the low and normal/high ETCO2 groups (5 vs 8, p=0.48). Compared to normal/high ETCO2, low ETCO2 correlated with increased unadjusted odds of mortality (OR 5.06), in-hospital complications (OR 2.06), and blood transfusion requirement (OR 3.05), p<0.05. Low ETCO2 was associated with 7.25 odds of mortality (95% CI 2.19,23.97, p=0.001) and 3.94 odds of blood transfusion (95% CI 1.32-11.78) after adjusting for age, ISS, and scene GCS. All but one of the massive transfusion patients (N = 8/9) had a low pre-hospital ETCO2. CONCLUSIONS: Low initial pre-hospital ETCO2 associates with poor clinical outcomes despite similar ISS and mechanisms of injury. ETCO2 is a potentially useful pre-hospital point-of-care tool to aid triage of trauma patients as it may identify hemorrhaging patients and predict mortality.

"Do You Need a Doctor's Note?" Factors Leading to Delayed Return to Work after Blunt Chest Trauma.

BACKGROUND: Blunt chest trauma is associated with significant morbidity, but the long-term functional status for these patients is less well-known. Return to work (RTW) is a benchmark for functional recovery in trauma patients, but minimal data exist regarding RTW following blunt chest trauma. MATERIALS AND METHODS: Patients ≥ 18 y old admitted to a Level 1 trauma center following blunt chest trauma with ≥ 3 rib fractures and length of stay (LOS) ≥ 3 d were included. An electronic survey assessing RTW was administered to patients after discharge. Patients were stratified as having delayed RTW (> 3 mo after discharge) or self-reported worse activities-of-daily-living (ADL) function after injury. Patient demographics, outcomes, and injury characteristics were compared between groups. RESULTS: Median time to RTW was 3 mo (IQR 2,5). Patients with delayed RTW had higher odds of having more rib fractures than those with RTW ≤ 3 mo (median 10 versus 7; OR:1.24, 95%CI:1.04,1.48) as well as a longer LOS (median 13 versus 7 d; OR:1.15, 95% CI:1.04,1.30). Patients with stable ADL after trauma returned to work earlier than those reporting worse ADL (median 2 versus 3.5 mo, P < 0.01). 23.6% of respondents took longer than 5 mo to return to independent functioning, and 50% of respondents' report limitations in daily activities due to physical health after discharge. CONCLUSIONS: The significant proportion of patients with poor physical health and functional status suggests ongoing burden of injury after discharge. Patients with longer LOS and greater number of rib fractures may be at highest risk for delayed RTW after injury.

Enhancing Medical Student Education and Combating Mistreatment During a Surgery Clerkship With a Novel Educational Tool: A Pilot Study.

BACKGROUND: Medical education changes dramatically from preclinical to clinical years, and the learning environment becomes key as students strive to develop clinical competence and informed career decisions. This change becomes heightened on a surgical clerkship where student mistreatment is often perceived, and the fast-paced nature of surgery can result in limited resident-student interactions and time for examination preparation. OBJECTIVE: To evaluate medical student and resident perception of educational strategies during a surgical clerkship and to determine whether the addition of a novel educational tool would increase satisfaction with the surgical clerkship on examination preparation and team dynamics. SETTING: University of North Carolina at Chapel Hill, Department of Surgery. STUDY DESIGN: During the 2018-2019 academic year, a 10-item "Ask a Resident Topics" (ART) card of high yield general surgery topics was implemented as part of the third-year surgery clerkship curriculum. Students were asked to review a topic and then discuss it with a general surgery resident. They were expected to complete at least 6 of 10 topics by the end of the rotation for credit. At the end of the year, third-year medical students were administered a 23-item survey regarding their experience on the surgery clerkship and with the ART cards. Fourth-year medical students and those students at satellite sites who did not receive the ART cards were administered the same survey, minus specific questions about the ART card, and were used as a preintervention control. General surgery residents who participated in teaching were similarly surveyed. RESULTS: Of those students that completed the ART cards, 84% felt it improved their understanding of general surgery and were more likely to report the surgery clerkship prepared them well for the NBME examination compared to those who did not (Χ2 (1, N = 87) = 4.95, p = 0.03). They were also more likely to report residents were willing to discuss surgery topics with them (Χ2 (1, N = 87) = 2.77, p = 0.10). Seventy-three percent of students thought the card did not add undue stress to their clerkship. Sixty-three percent of all students felt they were a productive member of the surgery team, and this did not vary by intervention group (Χ2 (1, N = 87) = 0.03, p = 0.9). Students who completed the ART card were more likely to report being interested in surgery than those who did not (Χ2 (1, N = 87) = 4.20, p = 0.04). Hundred percent of residents surveyed felt the ART card provided value for themselves as a teacher and for the student as a learner. CONCLUSIONS: The ART card is mutually beneficial to both residents and medical students during the surgical clerkship. This tool is easy to implement, helps students improve their understanding of general surgery, increases camaraderie among the surgical team, and has a positive impact on students pursuing a career in surgery.

Hypertension in the Young Adult Trauma Population: Rethinking the Traditional "Incidentaloma".

BACKGROUND: Hypertension (HTN) is a treatable and preventable risk factor for cardiovascular disease that is often overlooked in young adults. As a result, young patients with HTN may enter the health care system as a trauma without a preexisting diagnosis. The potential impact of HTN (diagnosed and undiagnosed) on trauma outcomes is not known. MATERIALS AND METHODS: Patients aged 18-39 y from the 2013-2017 North Carolina Trauma Registry were included. Patients were stratified as having no HTN, previously diagnosed HTN (PD-HTN), or newly diagnosed HTN (ND-HTN) during a trauma admission. Multivariable logistic and linear regression compared inpatient outcomes between patients with and without HTN, as well as ND-HTN and PD-HTN. RESULTS: Six percent of trauma patients were diagnosed with HTN (n = 1906; 14% ND-HTN). Those with HTN were more likely to have an inpatient complication (odds ratio [OR]: 1.65, 95% confidence interval [CI]: 1.32-2.07) and intensive care unit stay (OR: 1.28, 95% CI: 1.12-1.46) compared with patients without HTN. Compared with PD-HTN, those with ND-HTN were more likely to present with extreme injury. In addition, patients with ND-HTN had higher odds of inpatient complications (OR: 1.95, 95% CI: 1.18-3.22) and 30-d readmission (OR: 2.00, 95% CI: 0.95-4.20) after accounting for demographics and injury severity. CONCLUSIONS: More than 10% of young adult trauma patients with HTN are not diagnosed before admission. HTN appears to have a detrimental impact on patient outcomes, with newly diagnosed patients having the worst outcomes. Trauma may serve as an opportunity for the diagnosis and treatment of HTN in young adults. Future studies should assess the impact of intervention on trauma outcomes.

Delving deeper into disparity: The impact of health literacy on the surgical care of breast cancer patients.

BACKGROUND: Breast surgical oncology is a unique field that involves complex cancer management and longstanding patient interactions with the healthcare system, making it potentially challenging for patients with low health literacy. The purpose of this review is to summarize the current knowledge regarding health literacy in breast cancer and identify future directions for research and potential intervention in breast surgical oncology. DATA SOURCES: A search of relevant literature querying PubMed and Science Direct was performed and included the following keywords: health literacy, breast cancer, breast surgical oncology, surgery, outcomes, prevention, screening, healthcare utilization, chronic disease. CONCLUSIONS: Limited health literacy may detrimentally affect understanding and outcomes in breast surgical oncology. Identifying ways providers can improve patient understanding and utilization of health information is important, and surgeons may have a pivotal role. Further studies addressing health literacy in breast surgical oncology is needed in order to better optimize care of patients.

Aortic root replacement in a patient following congenital aortico-left ventricular tunnel repair in childhood.

Congenital aortico-left ventricular tunnel requires surgical repair during childhood. Long-term surveillance is essential in these patients given the risk for aortic aneurysm development in adulthood. We describe an aortic root replacement for an aortic aneurysm five decades following the closure of an aortic-left ventricular tunnel.
