Hands-On: Investigating the role of physical manipulatives in spatial training.

Studies show that spatial interventions lead to improvements in mathematics. However, outcomes vary based on whether physical manipulatives (embodied action) are used during training. This study compares the effects of embodied and non-embodied spatial interventions on spatial and mathematics outcomes. The study has a randomized, controlled, pre-post, follow-up, training design (N = 182; mean age 8 years; 49% female; 83.5% White). We show that both embodied and non-embodied spatial training approaches improve spatial skills compared to control. However, we conclude that embodied spatial training using physical manipulatives leads to larger, more consistent gains in mathematics and greater depth of spatial processing than non-embodied training. These findings highlight the potential of spatial activities, particularly those that use physical materials, for improving children's mathematics skills.

Treatment of Chronic Hypertrophic Burn Scars With a Fractional CO 2 Laser Is Well Tolerated in an Outpatient Clinic Setting.

INTRODUCTION: The necessity of treating hypertrophic burn scars has expanded significantly with increased burn survivorship. Ablative lasers, such as carbon dioxide (CO 2 ) lasers, have been the most common nonoperative option for improving functional outcomes in severe recalcitrant hypertrophic burn scars. However, the overwhelming majority of ablative lasers used for this indication require a combination of systemic analgesia, sedation, and/or general anesthesia due to the painful nature of the procedure. More recently, the technology of ablative lasers has advanced and is more tolerable than their first-generation counterparts. Herein, we hypothesized that refractory hypertrophic burn scars can be treated by a CO 2 laser in an outpatient clinic. METHODS: We enrolled 17 consecutive patients with chronic hypertrophic burn scars that were treated with a CO 2 laser. All patients were treated in the outpatient clinic with a combination of a topical solution (23% lidocaine and 7% tetracaine) applied to the scar 30 minutes before the procedure, Cryo 6 air chiller by Zimmer, and some patients received a mixture of N 2 O/O 2 . Laser treatments were repeated every 4 to 8 weeks until the patient's goals were met. Each patient completed a standardized questionnaire to assess tolerability and patient satisfaction of functional results. RESULTS: All patients tolerated the laser well in the outpatient clinic setting, with 0% indicating "not tolerable," 70.6% "tolerable," and 29.4% "very tolerable." Each patient received more than 1 laser treatment for the following complaints: decreased range of motion (n = 16, 94.1%), pain (n = 11, 64.7%), or pruritis (n = 12, 70.6%). Patients were also satisfied with the results of the laser treatments ("no improvement or worsened" = 0%, "improved" = 47.1%, and "significant improvement" = 52.9%). The age of patient, type of burn, location of burn, presence of skin graft, or age of scar did not significantly affect the tolerability of treatment or satisfaction of outcome. CONCLUSIONS: The treatment of chronic hypertrophic burn scars with a CO 2 laser is well tolerated in an outpatient clinic setting in select patients. Patients reported a high level of satisfaction with notable improvement in functional and cosmetic outcomes.

Use of lateral femoral cutaneous nerve blocks by landmark technique is ineffective in decreasing narcotic usage after skin grafts: A retrospective case-control study.

INTRODUCTION: Cutaneous burns are commonly treated with autologous skin grafts. Following skin grafting, many patients complain of pain at the donor site. Donor sites are taken most commonly from the lateral thigh, which is innervated by the lateral femoral cutaneous nerve (LFCN). Use of a LFCN blocks should decrease nociception from the donor site. METHODS: Our group began utilizing LFCN blocks in 2019. Utilizing anatomic landmarks, LFCN blocks were performed on all patients who received autologous skin grafts to reduce perioperative pain. A retrospective cohort study was performed on all patients with 10% or less total body surface areas burns who received an autologous skin graft. A similar cohort from 2016, prior to use of any local or regional analgesia, was used as a historical control. Post-operative enteral and parenteral narcotic analgesics were collected for each post-operative day up to day 5 or discharge (whichever came first) and converted to morphine milligram equivalents (MME) to quantify analgesia after surgery. RESULTS: Chart review identified 55 patients in the 2020 cohort. Fifty-five patients from the 2016 cohort were matched based upon size of skin graft, total body surface area (TBSA) burned, gender, and age. There were no statistically significant differences between the two groups in terms of size of graft, TBSA burned, age, gender, or type of burn. When examining narcotics usage in the immediate perioperative period (days 0-2), we found no difference between the two groups for total MME (113 vs 133, p = 0.28) or IV MME (38 vs 33, p = 0.45). Similar relationships existed in the extended post-operative period (days 1-5) for total MME (149 vs. 188, t = 0.22) or IV MME (37 vs. 50, t = 0.25). Examining daily narcotic usage also yielded no statistically different values. CONCLUSION: Our data shows that use of LFCN block by landmark technique did not reduce narcotic usage in patients that undergo skin grafting procedures. Future studies should consider ultrasound-guided LFCN blocks.

Patient Resiliency and Caregiver Burden After Traumatic Spinal Cord Injury Resulting in Quadriplegia.

Traumatic spinal cord injury (tSCI) resulting in quadriplegia is a life-altering injury for patients and caregivers. We conducted a retrospective review of patients treated for tSCI and quadriplegia at a level 1 trauma center to assess quality of life (QOL), socioeconomic factors, and mortality. Patients and caregivers were surveyed. Of the 65 patients included, 33 contacts were made. Seventeen surveys were completed (12 caregivers and 5 patients). Six unreachable patients were confirmed alive via medical record. Mortality rate among these 39 accessible patients was 23% (n = 9). Medicaid and uninsured patients experienced longer hospital length of stay (P < .0001) and discharged to home or nursing facilities (P < .0001) more often than those with private insurance or Medicare. Patients reported overall "good" QOL (80%) while caregivers reported overall decreased QOL markers. Our results reflect the resilience among this patient population, but also highlight the impact of this life-altering injury on the caregiver.

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.

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.

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.

Stress Disorders: the Trauma Surgeon as the Second Victim.

Purpose of Review: We review the vocabulary and studies regarding stress disorders, as it relates to trauma care providers, specifically trauma surgeons. In addition, we make recommendations regarding strategies to address the needs identified and future areas of research to assess the adequacy of these strategies. Recent Findings: Stress disorders in trauma are common and constant, identified at levels similar to those seen among first-responders to mass-casualty events. These disorders are identified at every level-from trainee to the most experienced. Trauma surgeons experience the trauma firsthand, as well as through forced re-traumatization as a part of routine care. High levels of cumulative stress result due to the volume of patients that can be difficult to process due to the frequency of shifts and disrupted sleep patterns. This level of chronic stress can lead to a cycle of burnout and increased stress, which is harmful to surgeons and patients. Summary: Stress disorders are common and poorly understood. Treatment options are infrequently encountered. In order to more adequately respond to this, systematic change is necessary.

Project Inspire pilot study: A hospital-led comprehensive intervention reduces gun violence among juveniles delinquent of gun crimes.

BACKGROUND: Gun violence disproportionately affects young Black men, but the impact extends to families and communities. Those at highest risk are teens delinquent of gun crimes. While there is no nationally accepted juvenile rate of recidivism, previous literature reveals rearrest rates from 50% to 80% in high-risk youth, and some reports show that up to 40% of delinquent juveniles are incarcerated in adult prisons before the age of 25 years. We hypothesize that Project Inspire, a hospital-led comprehensive intervention, reduces recidivism among high-risk teens. METHODS: Led by a level 1 trauma center, key community stakeholders including the juvenile court, city, and city police department joined forces to create a community-wide program aimed at curbing gun violence in high-risk individuals. Participants, aged 13 to 18 years, are selected by the juvenile gun court. They underwent a rigorous 3-week program with a curriculum incorporating the following: trauma-informed training and confidence building, educational/professional development, financial literacy, entrepreneurship, and career-specific job shadowing and mentorship. Rates of recidivism were measured annually. RESULTS: Project Inspire has hosted two classes in 2018 and 2019, graduating nine participants aged 14 to 17 years. Sixty-seven percent were Black. All were males. At 1 year, none of the graduates reoffended. At 2 years, one participant reoffended. At 3 years, no additional participants reoffended. No graduate reoffended as a juvenile. Thus, the overall rate of recidivism for Project Inspire is 11% to date. Eighty-nine percent of graduates received a diploma, general educational development, or obtained employment. CONCLUSION: Project Inspire is a hospital-led initiative that effectively reduces recidivism among juveniles delinquent of gun crimes. This sets the framework for trauma centers nationwide to lead in establishing impactful, comprehensive, gun-violence intervention strategies. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level V.

Practitioners' perspectives on spatial reasoning in educational practice from birth to 7 years.

BACKGROUND: There is a growing evidence base for the importance of spatial reasoning for the development of mathematics. However, the extent to which this translates into practice is unknown. AIMS: We aimed to understand practitioners' perspectives on their understanding of spatial reasoning, the extent to which they recognize and implement spatial activities in their practice, and the barriers and opportunities to support spatial reasoning in the practice setting. SAMPLE: Study 1 (questionnaire) included 94 participants and Study 2 (focus groups) consisted of nine participants. Participants were educational practitioners working with children from birth to 7 years. METHODS: The study was mixed methods and included a questionnaire (Study 1) and a series of focus groups (Study 2). RESULTS: We found that whilst practitioners engage in a variety of activities that support spatial reasoning, most practitioners reported little confidence in their understanding of what spatial reasoning is. CONCLUSION: Informative and accessible resources are needed to broaden understanding of the definition of spatial reasoning and to outline opportunities to support spatial reasoning.

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.

Identifying Radiographic and Clinical Indicators to Reduce the Occurrence of Nontherapeutic Laparotomy for Blunt Bowel and Mesenteric Injury.

BACKGROUND: Roughly 5% of patients with blunt abdominal trauma (BAT) have a blunt bowel and/or mesenteric injury (BBMI). Determining the need for operative management in these patients can be challenging when hemodynamically stable. Single center studies have proposed scoring systems based on CT findings to guide management. Our study aimed to determine the predictability of abdominopelvic CT scan (CT A/P) findings in conjunction with clinical exam to determine the necessity of operative intervention for BBMI. METHODS: Patients presenting from 2017 to 2022 to the University of South Alabama Level 1 Trauma Center after motor vehicle collision were retrospectively reviewed. Patients with CT findings suggestive of BBMI were further analyzed, noting CT findings, Glasgow coma scale (GCS), shock index, abdominal exam, operative or nonoperative management, and intraoperative intervention. RESULTS: 1098 patients with BAT underwent CT A/P. 139 patients had ≥1 finding suggestive of BBMI. 38 patients underwent surgical exploration and 30 had surgically confirmed BBMI. 27 patients required intervention for BBMI. Univariate analysis indicated that pneumoperitoneum (p < 0.0001), active extravasation of contrast (p = 0.0001), hemoperitoneum without solid organ injury (SOI) (p < 0.0001), peritonitis (p < 0.0001), and mesenteric stranding(p < 0.05) were significantly associated with intervention. CONCLUSION: In total, 30 patients had surgically confirmed BBMI. Active extravasation, pneumoperitoneum, hemoperitoneum without SOI, mesenteric stranding, and peritonitis were significant indicators of BBMI requiring intervention. CT and clinical findings cannot reliably predict the need for surgical intervention without ≥1 of these findings. Initial nonoperative management with serial clinical exams should be strongly considered to reduce incidence of nontherapeutic laparotomies.

Incidence and Severity of Medication Reconciliation Discrepancies in Trauma Patients.

Trauma patients are especially vulnerable to inadvertent medication reconciliation discrepancies. We conducted a prospective study to evaluate the USA Health University Hospital's incidence and type of inadvertent medication reconciliation discrepancies among trauma patients. Patients were interviewed for accuracy of their admission medication reconciliation (AMR). Eighty-nine patients were included in this study. Twenty-six patients (29%) never received an AMR. There were 107 inadvertent medication reconciliation errors identified from 30 separate patients (48%), for a rate of 3.6 errors per patient with any error. There was a significant difference in the frequency of inadvertent medication reconciliation discrepancies for patients with >5 medication compared to those with fewer (P = .00029). In conclusion, trauma centers must be adequately staffed to provide timely, accurate, and available medication lists so that patients can be appropriately cared for.

Social Determinants of Health Impact Physical Recovery After Blunt Injury.

As defined by the United States Department of Health and Human Services, the Social Determinants of Health (SDOH) are conditions in the environment that affect health function and outcomes. The SDOH are divided into the following categories: economic stability, education access and quality, health care access and quality, neighborhood and built environment, and social and community content. It is known that SDOH impact long-term health outcomes. The influence that SDOH have on physical recovery after acute injury is less understood, however. In this study, patients who suffered a traumatic blunt injury completed a survey 12-14 months post-injury to assess their SDOH and physical health before and after their injury. The results showed that for the cohort of patients studied SDOH was the greatest predictor of long-term recovery, having a stronger correlation with recovery than injury severity score (ISS) or hospital length of stay (HLOS).

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.

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.

Defining Pathogen and Susceptibility Patterns for Early Versus Late Ventilator Associated Pneumonia in Trauma Patients to Guide Empiric Treatment Decisions.

INTRODUCTION: Studies have demonstrated that trauma patients with early-ventilator associated pneumonia (early-VAP, < 7 days) have decreased risk of methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa infections. We hypothesize that routinely using broad-spectrum antibiotics is unnecessary to treat trauma patients with the diagnosis of early-VAP. METHODS: This retrospective cohort study included adult trauma patients with the diagnosis of VAP. The primary outcome was the presence of MRSA and/or P. aeruginosa in patients with early- and late-VAP. Secondary outcomes included the bacterial susceptibility of pathogens to methicillin, ampicillin/sulbactam, ceftriaxone, piperacillin/tazobactam, and cefepime. Intensive care unit (ICU) and hospital length of stay (LOS), ventilator-free days, and in-hospital mortality were also collected. RESULTS: 164 patients met inclusion criteria, and 208 organisms (n = 90 early vs n = 118 late) were identified by respiratory culture. The incidence of MRSA and P. aeruginosa in early-VAP was 7.7% (7/90) and 5.6% (5/90), respectively. The susceptibility of bacteria causing early-VAP to ampicillin/sulbactam and ceftriaxone was 73.3% (66/90) and 83.3% (75/90), respectively. Ventilator-free days at 30 days was similar between groups (P = .649). Patients with late-VAP spent more time in the ICU (P = .040); however, in-hospital mortality was higher in the early-VAP group (P = .012). CONCLUSIONS: Ampicillin/sulbactam or ceftriaxone monotherapy did not provide reliable broad-spectrum coverage for early-VAP in our cohort. These findings highlight the importance of each institution performing a similar analysis to ensure adequate initial treatment of VAP.

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.

Association Between Adverse Childhood Experiences and Posttraumatic Stress Disorder Symptoms in Adults With Injury.

This case-control study examines the risk factors associated with acute stress disorder in patients with severe injury.
