Scanning the aged to minimize missed injury: An EAST multicenter study.

BACKGROUND: Despite the high incidence of blunt trauma in older adults, there is a lack of evidence-based guidance for computed tomography (CT) imaging in this population. We aimed to identify an algorithm to guide use of a Pan-Scan (Head/C-spine/Torso) or a Selective Scan (Head/C-spine ± Torso). We hypothesized that a patient's initial history and exam could be used to guide imaging. METHODS: We prospectively studied blunt trauma patients aged 65+ at 18 Level I/II trauma centers. Patients presenting >24 h after injury or who died upon arrival were excluded. We collected history and physical elements and final injury diagnoses. Injury diagnoses were categorized into CT body regions of Head/C-spine or Torso (chest, abdomen/pelvis, and T/L spine). Using machine learning and regression modeling as well as a priori clinical algorithms based, we tested various decision rules against our dataset. Our priority was to identify a simple rule which could be applied at the bedside, maximizing sensitivity (Sens) and negative predictive value (NPV) to minimize missed injuries. RESULTS: We enrolled 5,498 patients with 3,082 injuries. Nearly half (47.1%, n = 2,587) had an injury within the defined CT body regions. No rule to guide a Pan-Scan could be identified with suitable Sens/NPV for clinical use. A clinical algorithm to identify patients for Pan-Scan, using a combination of physical exam findings and specific high-risk criteria, was identified and had a Sens of 0.94 and NPV of 0.86 This rule would have identified injuries in all but 90 patients (1.6%) and would theoretically spare 11.9% (655) of blunt trauma patients a torso CT. CONCLUSIONS: Our findings advocate for Head/Cspine CT in all geriatric patients with the addition of torso CT in the setting of positive clinical findings and high-risk criteria. Prospective validation of this rule could lead to streamlined diagnostic care of this growing trauma population. LEVEL OF EVIDENCE: Level 2, Diagnostic Tests or Criteria.

Time to Mobility Is Associated With Pulmonary Complications in Patients With Spine Fractures.

INTRODUCTION: Treatment of spine fractures may require periods of prolonged immobilization which prevents effective pulmonary toileting. We hypothesized that patients with longer time to mobilization, as measured by time to first physical therapy (PT) session, would have higher pulmonary complications. METHODS: We performed a retrospective review of all trauma patients with cervical and thoracolumbar spinal fractures admitted to a level 1 trauma center over a 12-month period. Demographic data collection included age, gender, BMI, pulmonary comorbidities, concomitant rib fractures, admission GCS, Injury Severity Score (ISS), GCS at 24 h, treatment with cervical or thoracolumbar immobilization, and time to first PT evaluation. The primary outcome was the presence of any one of the following complications: unplanned intubation, pneumonia, or mortality at 30 days. Multivariable logistic regression analysis was used to assess significant predictors of pulmonary complication. RESULTS: In total, 491 patients were identified. In terms of overall pulmonary complications, 10% developed pneumonia, 13% had unplanned intubation, and 6% died within 30 days. In total, 19% developed one or more complication. Overall, 25% of patients were seen by PT <48 h, 33% between 48 and 96 h, 19% at 96 h to 1 week, and 7% > 1 week. Multivariable logistic regression analysis showed that time to PT session (OR 1.010, 95% CI 1.005-1.016) and ISS (OR 1.063, 95% CI 1.026-1.102) were independently associated with pulmonary complication. CONCLUSION: Time to mobility is independently associated with pulmonary complications in patients with spine fractures.

A Single Hospital-Wide Antibiogram is Insufficient to Account for Differences in Antibiotic Resistance Patterns Across Multiple ICUs.

BACKGROUND: Infection is a common cause of mortality within intensive care units (ICUs). Antibiotic resistance patterns and culture data are used to create antibiograms. Knowledge of antibiograms facilitates guiding empiric therapies and reduces mortality. Most major hospitals utilize data collection to create hospital-wide antibiograms. Previous studies have shown significant differences in susceptibility patterns between hospital wards and ICUs. We hypothesize that institutional or combined ICU antibiograms are inadequate to account for differences in susceptibility for patients in individual ICUs. METHODS: Culture and susceptibility data were reviewed over a 1-year period for 13 bacteria in the following ICUs: Surgical/Trauma, Medical, Neuroscience, Burn, and Emergency department. Antibiotic management decisions are made by individual teams. RESULTS: Nine species had sufficient data for inclusion into an All-ICU antibiogram. E coli and S aureus were the most common isolates. Seven species had significant differences in susceptibility patterns between ICUs. E cloacae showed higher rates of resistance to multiple antibiotics in the STICU than other ICUs. P aeruginosa susceptibility rates in the NSICU and BICU were 88% and 92%, respectively, compared to 60% and 55% in the STICU and MICU. Cephalosporins and Aztreonam had reduced efficacy against E coli in the NSICU, however remain effective in other ICUs. CONCLUSIONS: The results of this study show that different ICUs do have variability in antibiotic susceptibility patterns within a single hospital. While this only represents a single institution, it shows that the use of hospital-wide antibiograms is inadequate for creating empiric antibiotic protocols within individual ICUs.

Monotherapy Antibiotic Prophylaxis of Lower Extremity Long Bone Type III Open Fractures.

Gustilo type III open fractures involve extensive soft tissue damage and wound contamination that pose significant infection risks. The historical standard for antibiotic prophylaxis has been cefazolin and gentamicin. We conducted a retrospective cohort study of lower extremity type III open fractures treated with ceftriaxone alone for prophylaxis. Eighty-six patients were identified. Nearly all (98%) were managed with appropriate antibiotics, but only 55 (64%) received prophylaxis within 1 hour. Overall, there were 12 infections. This infection rate was not statistically different than the reported literature (14% vs 19%, P = .20). The infection rate between those who received antibiotics within 1 hour was not statistically different from those who got it beyond 1 hour (15% vs 13%, P = .98). In conclusion, the use of ceftriaxone as monotherapy for antibiotic prophylaxis in lower extremity type III open fractures is not statistically different than the use of historic prophylactic regimens.

Diabetes in Trauma Patients: A Potential Gateway to a Medical Home.

BACKGROUND: Diabetes is a major determinant of health outcomes. Trauma patients are disproportionately from lower socioeconomic status, where lack of access to health care prevents timely treatment. Trauma centers could play a role in identifying patients in need of improved glucose management, but the current burden of disease is not known. We assessed the incidence of patients in need of intervention that presented to a level 1 trauma center over a 6-month period. METHODS: A retrospective chart review over 6 months of all trauma patients admitted to a level 1 trauma center was performed. Patients' past medical history (PMH), medication reconciliation, and hemoglobin A1c (HbA1c) were recorded on initial assessment; patients <18 years old, lacking an HbA1c, or missing PMH were excluded. Patients with PMH of diabetes or antihyperglycemic use were classified by HbA1c: well-controlled ≤8.0% or poorly controlled >8.0%. Patients with no history of diabetes or antihyperglycemic use were classified based on their HbA1c: non-diabetic <5.7%, pre-diabetic 5.7-6.4%, and undiagnosed diabetic ≥6.5%. RESULTS: Overall, 1377 patients were identified. After exclusion criteria, 903 patients were classified as follows: 593 (66%) non-diabetics, 160 (18%) pre-diabetics, and 150 (17%) diabetics. Fifteen diabetics were undiagnosed; 39 of the diagnosed diabetics were poorly controlled. Including pre-diabetics, a total of 214 (24%) trauma patients were in need of improved glycemic control. DISCUSSION: One in four trauma patients would benefit from improved outpatient glycemic management, representing a missed opportunity for preventative health care. Trauma centers should develop strategies to meet this need as part of their post-discharge care.

Admission Medication Reconciliation Discrepancies in Trauma Patients: Consistent Nursing Care May Not Be the Answer.

Inadvertent medication reconciliation discrepancies are common among trauma patient populations. We conducted a prospective study at a level 1 trauma center to assess incidence of inadvertent medication reconciliation discrepancies following decreased reliance on short-term nursing staff. Patients and independent sources were interviewed for home medication lists and compared to admission medication reconciliation (AMR) lists. Of the 108 patients included, 37 patients (34%) never received an AMR. Of the 71 patients that had a completed AMR, 42 patients (59%) had one or more errors, with total 154 errors across all patients, for a rate of 3.7 per patient with any discrepancy. Patients taking ≥ 5 medications were significantly more likely to have an incomplete or inaccurate AMR than those taking <5 medications (89% vs 41%, P < .0001). Decreased reliance on short-term nursing staff did not decrease inadvertent admission medication reconciliation discrepancies. Additional interventions to decrease risk of medication administration errors are needed.

Effects of the COVID-19 Pandemic on the Trauma Population in a Level 1 Trauma Center.

In this study, we evaluated the effects of the pandemic on our trauma population. We performed a retrospective review of the trauma registry in the 2 years prior, and then 2 years during the pandemic. We evaluated age, race, gender, injury severity score (ISS), mechanism of trauma, rate of self-inflicted injury, rate of gunshot wounds (GSW), presence of EtOH, drug screen results, mortality, rate of burn traumas, and zip code of residence. Our query captured 5 054 patients before, and 5 731 during the pandemic. We found no statistical difference in age, gender, mechanism of trauma, rate of self-inflicted injuries, and mortality during the pandemic when compared to before. There were statistically significant differences in race, ISS, rate of GSWs, EtOH use, drug screen results, and burn traumas. Geospatial mapping found a rise in GSWs for zip code 36606. Gun violence and substance use rose in our trauma population during COVID-19.

A Multidisciplinary Approach for the Management of Portal Vein Thrombosis.

Portal venous thrombosis (PVT) is an uncommon disease associated with highly morbid conditions such as intestinal ischemia and portal hypertension. Patients at higher risk of developing PVT include those with cirrhosis, malignancy, or prothrombotic states. The mainstay of treatment is early initiation of anticoagulation. The first case is a 49-year-old female diagnosed with a cecal mass and PVT. She was started on anticoagulation and underwent a right hemicolectomy with several small bowel resections. She developed portal hypertension that required TIPS and mechanical thrombectomy. The second patient is a 65-year-old female found to have PVT. She was anticoagulated with heparin and given systemic TPA. She developed intestinal ischemia and portal hypertension requiring small bowel resection, TIPS, and mechanical thrombectomy. These cases give insight into the impact of a multidisciplinary team approach to PVT. The role and timing of endovascular treatment is not well established and needs to be further investigated.

The Impact of Relocating a Trauma Center: Retrospective Observations on Payer Demographics and Cost-Analysis.

BACKGROUND: Standardization of trauma centers improves quality of care, yet that comes with financial challenges. The decision to designate a trauma center typically focuses on access, quality of care, and the needs of the local community, but less often considers the financial viability of the trauma center. A level-1 trauma center was relocated in 2017 and this presented an opportunity to compare financial data at two separate locations in the same city. METHODS: A retrospective review was performed on the local trauma registry and billing database in all patients aged ≥19 years on the trauma service before and after the move. RESULTS: 3041 patients were included (pre-move: 1151; post-move: 1890). After the move, patients were older (9.5 years), and more were females (14.9%) and white (16.5%). Increases in blunt injuries (7.6%), falls (14.8%), and motor vehicle accidents (1.7%) were observed after the move. After the move, patients were less likely to be discharged home (6.5%) and more likely to go to a skilled nursing facility (3%) or inpatient rehabilitation (5.5%). Post-move more patients had Medicare (12.6%) or commercial (8.5%) insurance and charges per patient decreased by $2,833, while charges collected per patient increased by $2425. Patients were seen from a broader distribution of zip codes post-move. DISCUSSION: Relocating a trauma center did improve financial viability for this institution. Future studies should consider the impact on the surrounding community and other trauma centers. LEVEL OF EVIDENCE: Level IV.

Aortic Injury From High-Speed Deceleration Against a Lap Belt in a 10-year-Old.

Traumatic aortic injuries in children and adolescents are rare, and even more rare are blunt traumatic injury to the abdominal aorta in this population. Therefore, there are few reports discussing the presentation and repair of such injuries, especially within the pediatric population. We report the successful repair of traumatic abdominal aortic transection in a 10-year-old female after a high speed MVC. She arrived in extremis with a seatbelt sign and was taken emergently for damage control laparotomy with subsequent postoperative CT findings of aortic transection/dissection at L3 with active extravasation. She immediately underwent open thrombectomy of the bilateral iliac arteries, and repair of her aortic injury with a 12 × 7 mm Hemashield interposition graft extending just distal to the IMA and 1 cm proximal to the aortic bifurcation. There are little data regarding long-term outcomes of pediatric patients undergoing different aortic repair techniques, and further research is needed.

Blunt Cerebrovascular Injury (BCVI) Management: Is There a Right Answer?

Blunt cerebrovascular injury (BCVI) results from blunt trauma causing injury to the carotid and/or vertebral arteries. Its most severe manifestation is stroke. The purpose of this study was to evaluate the incidence, management, and outcomes of BCVI at a level one trauma/stroke center. Data on patients diagnosed with BCVI from 2016 to 2021 were extracted from the USA Health trauma registry with associated intervention performed and patient outcomes. Of the 97 patients identified, 16.5% presented with stroke-like symptoms (SS). Medical management was employed for 75%. Intravascular stent alone was utilized for 18.8%. The mean age of symptomatic BCVI patients was 37.6 with a mean injury severity score (ISS) of 38.2. Within the asymptomatic population, 58% received medical management and 3.7% underwent combination therapy. The mean age of asymptomatic BCVI patients was 46.9 with a mean ISS of 20.3. There were 6 mortalities, only one BCVI related.

Incidence and Outcomes of Undiagnosed and Untreated Diabetes Mellitus in Trauma Patients.

Diabetes is a major determinate for mortality in trauma patients. Many diabetics are undiagnosed or poorly controlled. Trauma patients disproportionately come from lower socioeconomic status, making missed diagnoses more likely. We aimed to quantify the incidence of undiagnosed or poorly controlled diabetics assessed at a Level 1 Trauma Center. We did a retrospective chart review of admitted trauma patients over a one-month period. Past Medical History, home medication lists, and Hemoglobin A1c on admission were recorded for each patient. We determined that 30 of 173 trauma patients qualifying for the study were diabetic. Furthermore, 30% of these diabetics were undiagnosed or had poorly controlled diabetes. Undiagnosed pre-diabetics made up 20% of the entire study group. Our data show that 26% of trauma patients would benefit from an intervention for improved glucose control. Trauma centers should consider creating routine clinical practice guidelines to identify at-risk patients and provide intervention for long-term management.

The Impact of Relocating a Trauma Center: Observations on Patient Injury Demographics and Resident Volumes.

Introduction Changing the physical zip code location of an academic trauma center may affect the distribution and surgical volume of its trauma patients. General surgical residency case log requirements may also be affected. This study describes the impact of moving a level I trauma center to a different zip code location, on the hospital and resident trauma case volumes. Methods This retrospective analysis included all patients within the local trauma registry across two fiscal years representing the pre- and post-move timeframes. Variables collected included patient basic sociodemographic and injury information, trauma activation level and transfer status, management (operative management [OPM] versus non-operative management [NOPM]), and resident case logs. Results During fiscal years 2016-2017 and 2017-2018, 3,025 patients were included. Pre-move and post-move trauma volumes were 1,208 and 1,817 respectively. Post-move changes demonstrated differences in basic sociodemographics, with differences in age (six years older), a shift toward white and away from black (12.89%), and males being seen more frequently (11.87%). Injury severity score distribution shifted (7.72%) towards less severe trauma scores (<15), the percentage of patients with blunt trauma (4.19%) and falls increased (ground level and greater than 1 meter, 9.78%) while the number of patients considered full activations were decreased (15.67%). Proportions of OPM and NOPM trauma cases remained unchanged with the exception of a reduction in emergent operative trauma (3.1%). Resident case logs requirements were met both pre- and post-move. Conclusion Relocating the trauma center to a different zip code location did not negatively impact our resident case volumes. Total trauma volumes were increased, with a shift in the demographics and severity distribution of injuries.

Takotsubo Cardiomyopathy and Trauma: The Role of Injuries as Physical Stressors.

INTRODUCTION: Physical stressors are common predisposing factors for takotsubo cardiomyopathy (TTC). However, the role of traumatic injuries in TTC has not been well defined. This study describes the characteristics of TTC in the broad spectrum of traumatic injuries using the information available in the National Trauma Data Bank (NTDB). MATERIALS AND METHODS: This retrospective study analyzed trauma patients ≥ 18 years old in the NTDB, from 2007 to 2018, with a diagnosis of TTC. RESULTS: A total of 95 TTC diagnoses were found. The median age was 68 years old (interquartile range: 55-80). Patients were predominantly female (67.4%), white (88.4%), and sustained blunt mechanisms of injury (90.5%). Penetrating trauma was most common in males (16%). Most diagnoses were related to extremity trauma (53.7%), followed by head injury (26.3%). The most common severity scores were Glasgow Coma Scale (GCS) > 13 or < 8, and Injury Severity Score (ISS) < 15 or > 25. Males more commonly presented with GCS < 8 (68%), ISS > 25 (33%), high intensive care unit (ICU) admission rate (77.4%), and mechanical ventilation (51.6%). The median duration of the mechanical ventilation was eight days for both sexes. The ICU length of stay (LOS) was six days with a hospital LOS of nine days and a trend toward a longer LOS in males. The in-hospital mortality rate was 11.7% for both sexes. CONCLUSIONS: TTC in traumatic injuries is common at both ends of the severity spectrum and has different sex distribution. TTC patients are predominantly females and have more commonly extremity trauma than head injury. Males are more severely injured and under mechanical ventilation.

In-hospital outcomes of intercostal nerve cryoablation and surgical stabilization of rib fractures.

BACKGROUND: Severe pain and pulmonary complications commonly follow rib fractures, both of which may be improved by surgical stabilization of rib fractures (SSRFs). However, significant postoperative pain still persists which may negatively impact in-hospital outcomes. Combining intercostal nerve cryoablation (INCA) with SSRF may improve those outcomes by further decreasing postoperative pain, opioid consumption, and pulmonary complications. The hypothesis is that INCA plus SSRF reduces opioids consumption compared with SSRF alone. METHODS: The retrospective analysis included trauma patients 18 years or older who underwent SSRF, with or without INCA, in a Level I trauma center between 2015 and 2021. Patients received INCA at the surgeons' discretion based on familiarity with the procedure and absence of contraindications. Patients without INCA were the historical control group. Reported data include demographics, mechanism and severity of injury, number of ribs stabilized, cryoablated nerves, intubation rates and duration of mechanical ventilation. The primary outcome was total morphine milligrams equivalent consumption. Secondary outcomes were intensive care unit length of stay, hospital length of stay, incidence of pneumonia, and tracheostomy rates, and discharge disposition. Long-term outcomes were examined up to 6 months for adverse events. RESULTS: Sixty-eight patients were included, with 44 receiving INCA. There were no differences in rates of pneumonia ( p = 0.106) or duration of mechanical ventilation ( p = 0.687), and hospital length of stay was similar between groups ( p = 0.059). However, the INCA group demonstrated lower total morphine milligrams equivalent ( p = 0.002), shorter intensive care unit length of stay ( p = 0.021), higher likelihood of home discharge ( p = 0.044), and lower rate of intubation ( p = 0.002) and tracheostomy ( p = 0.032). CONCLUSION: Combining INCA with SSRF may further improve in-hospital outcomes for patients with traumatic rib fractures. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.
