ABSTRACT

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.

ABSTRACT

INTRODUCTION: When appropriately used, helicopter emergency medical services (HEMSs) allow for timely delivery of severely injured patients to definitive care. Inappropriate utilization of HEMSs results in increased cost to the patient and trauma system. The purpose of this study was to review current HEMS criteria in the central Gulf Coast region and evaluate for potential areas of triage refinement and cost savings. We hypothesized that a significant number of patients received potentially unwarranted HEMS transport. METHODS: A retrospective cohort study of all patients with trauma arriving to a level I trauma center by helicopter over 28 mo was performed; 381 patients with trauma and with HEMS transport from the scene were included. Data were collected from prehospital sources, as well as hospital chart review for each patient. The primary outcome was the rate of unwarranted HEMS transport. RESULTS: A total of 381 adult patients with trauma transported by the HEMS were analyzed, of which 34% were deemed potentially nonwarranted transports. The significant factors correlating with warranted HEMS transport included age, multiple long bone fractures, penetrating mechanism, and vehicle ejection. Insurance demographics did not correlate to transport modality. Many of these patients were transported from a location within the same county or the county adjacent to the trauma center. When comparing patients transported by ground and HEMSs from the same scene, no time savings were identified. Unwarranted transports at the trauma center represented an estimated health care expenditure of over $3 million. CONCLUSIONS: HEMSs may be overused in the central Gulf Coast region, creating the risk for a substantial resource and financial burden to the trauma system. Further collaboration is needed to establish HEMS triage criteria, that is, more appropriate use of resources.

ABSTRACT

BACKGROUND: Transplantation of lungs procured after donation after circulatory death (DCD) is challenging because postmortem metabolic degradation may engender susceptibility to ischemia-reperfusion (IR) injury. Because oxidative mitochondrial DNA (mtDNA) damage has been linked to endothelial barrier disruption in other models of IR injury, here we used a fusion protein construct targeting the DNA repair 8-oxoguanine DNA glycosylase-1 (OGG1) to mitochondria (mtOGG1) to determine if enhanced repair of mtDNA damage attenuates endothelial barrier dysfunction after IR injury in a rat model of lung procurement after DCD. MATERIALS AND METHODS: Lungs excised from donor rats 1 h after cardiac death were cold stored for 2 h after which they were perfused ex vivo in the absence and presence of mt-OGG1 or an inactive mt-OGG1 mutant. Lung endothelial barrier function and mtDNA integrity were determined during and at the end of perfusion, respectively. RESULTS AND CONCLUSIONS: Mitochondria-targeted OGG1 attenuated indices of lung endothelial dysfunction incurred after a 1h post-mortem period. Oxidative lung tissue mtDNA damage as well as accumulation of proinflammatory mtDNA fragments in lung perfusate, but not nuclear DNA fragments, also were reduced by mitochondria-targeted OGG1. A repair-deficient mt-OGG1 mutant failed to protect lungs from the adverse effects of DCD procurement. CONCLUSIONS: These findings suggest that endothelial barrier dysfunction in lungs procured after DCD is driven by mtDNA damage and point to strategies to enhance mtDNA repair in concert with EVLP as a means of alleviating DCD-related lung IR injury.

ABSTRACT

Fragments of the mitochondrial genome released into the systemic circulation after mechanical trauma, termed mitochondrial DNA damage-associated molecular patterns (mtDNA DAMPs), are thought to mediate the systemic inflammatory response syndrome. The close association between circulating mtDNA DAMP levels and outcome in sepsis suggests that bacteria also might be a stimulus for mtDNA DAMP release. To test this hypothesis, we measured mtDNA DAMP abundance in medium perfusing isolated rat lungs challenged with an intratracheal instillation of 5 × 10(7) colony-forming units of Pseudomonas aeruginosa (strain 103; PA103). Intratracheal PA103 caused rapid accumulation of selected 200-bp sequences of the mitochondrial genome in rat lung perfusate accompanied by marked increases in both lung tissue oxidative mtDNA damage and in the vascular filtration coefficient (Kf). Increases in lung tissue mtDNA damage, perfusate mtDNA DAMP abundance, and Kf were blocked by addition to the perfusion medium of a fusion protein targeting the DNA repair enzyme Ogg1 to mitochondria. Intra-arterial injection of mtDNA DAMPs prepared from rat liver mimicked the effect of PA103 on both Kf and lung mtDNA integrity. Effects of mtDNA and PA103 on Kf were also attenuated by an oligodeoxynucleotide inhibitor of Toll-like receptor 9 (TLR-9) by mitochondria-targeted Ogg1 and by addition of DNase1 to the perfusion medium. Collectively, these findings are consistent with a model wherein PA103 causes oxidative mtDNA damage leading to a feed-forward cycle of mtDNA DAMP formation and TLR-9-dependent mtDNA damage that culminates in acute lung injury.

ABSTRACT

BACKGROUND: Transfusion-related acute lung injury (TRALI) is the most frequent and severe complication in patients receiving multiple blood transfusions. Current pathogenic concepts hold that proinflammatory mediators present in transfused blood products are responsible for the initiation of TRALI, but the identity of the critical effector molecules is yet to be determined. We hypothesize that mtDNA damage-associated molecular patterns (DAMPs) are present in blood transfusion products, which may be important in the initiation of TRALI. METHODS: DNA was extracted from consecutive samples of packed red blood cells, fresh frozen plasma (FFP), and platelets procured from the local blood bank. Quantitative real-time polymerase chain reaction was used to quantify ≈200 bp sequences from the COX1, ND1, ND6, and D-loop regions of the mitochondrial genome. RESULTS: A range of mtDNA DAMPs were detected in all blood components measured, with FFP displaying the largest variation. CONCLUSIONS: We conclude that mtDNA DAMPs are present in packed red blood cells, FFP, and platelets. These observations provide proof of the concept that mtDNA DAMPs may be mediators of TRALI. Further studies are needed to test this hypothesis and to determine the origin of mtDNA DAMPs in transfused blood.

ABSTRACT

BACKGROUND: Recent studies identify large quantities of inflammatory cellular debris within Fresh Frozen Plasma (FFP). As FFP is a mainstay of hemorrhagic shock resuscitation, we used a porcine model of hemorrhagic shock and ischemia/reperfusion to investigate the inflammatory potential of plasma-derived cellular debris administered during resuscitation. METHODS: The porcine model of hemorrhagic shock included laparotomy with 35 % hemorrhage (Hem), 45 min of ischemia from supraceliac aortic occlusion with subsequent clamp release (IR), followed by protocolized resuscitation for 6 h. Cellular debris (Debris) was added to the resuscitation phase in three groups. The four groups consisted of Hem + IR (n = 4), Hem + IR + Debris (n = 3), Hem + Debris (n = 3), and IR + Debris (n = 3). A battery of laboratory, physiologic, cytokine, and outcome data were compared between groups. RESULTS: As expected, the Hem + IR group showed severe time dependent decrements in organ function and physiologic parameters. All animals that included both IR and Debris (Hem + IR + Debris or IR + Debris) died prior to the six-hour end point, while all animals in the Hem + IR and Hem + Debris survived. Cytokines measured at 30-60 min after initiation of resuscitation revealed significant differences in IL-18 and IL-1ß between all groups. CONCLUSIONS: Ischemia and reperfusion appear to prime the immune system to the deleterious effects of plasma-derived cellular debris. In the presence of ischemia and reperfusion, this model showed the equivalency of 100 % lethality when resuscitation included quantities of cellular debris at levels routinely administered to trauma patients during transfusion of FFP. A deeper understanding of the immunobiology of FFP-derived cellular debris is critical to optimize resuscitation for hemorrhagic shock.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Background: Sepsis is a life-threatening condition that results from a dysregulated host response to infection, leading to organ dysfunction. Despite the prevalence and associated socioeconomic costs, treatment of sepsis remains limited to antibiotics and supportive care, and a majority of intensive care unit (ICU) survivors develop long-term cognitive complications post-discharge. The present study identifies a novel regulatory relationship between amyloid-ß (Aß) and the inflammasome-caspase-1 axis as key innate immune mediators that define sepsis outcomes. Methods: Medical ICU patients and healthy individuals were consented for blood and clinical data collection. Plasma cytokine, caspase-1 and Aß levels were measured. Data were compared against indices of multiorgan injury and other clinical parameters. Additionally, recombinant proteins were tested in vitro to examine the effect of caspase-1 on a functional hallmark of Aß, namely aggregation. Results: Plasma caspase-1 levels displayed the best predictive value in discriminating ICU patients with sepsis from non-infected ICU patients (area under the receiver operating characteristic curve=0.7080). Plasma caspase-1 and the Aß isoform Aßx-40 showed a significant positive correlation and Aßx-40 associated with organ injury. Additionally, Aß plasma levels continued to rise from time of ICU admission to 7 days post-admission. In silico, Aß harbours a predicted caspase-1 cleavage site, and in vitro studies demonstrated that caspase-1 cleaved Aß to inhibit its auto-aggregation, suggesting a novel regulatory relationship. Conclusions: Aßx-40 and caspase-1 are potentially useful early indicators of sepsis and its attendant organ injury. Additionally, Aßx-40 has emerged as a potential culprit in the ensuing development of post-ICU syndrome.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: Our objective was to execute a prospective cohort study to determine relationships between plasma mtDNA DAMP levels and the occurrence of systemic inflammatory response syndrome (SIRS), multiple organ dysfunction syndrome (MODS), and mortality. BACKGROUND: Mitochondrial DNA damage-associated molecular patterns (DAMPs) accumulate in the circulation after severe injury. Observations in animal models demonstrate that mtDNA DAMPs contribute to organ dysfunction; however, the link between plasma mtDNA DAMPs and outcome in severely injured human subjects has not been established. METHODS: DNA was isolated from plasma samples taken from severely injured patients at hospital days 0, 1, and 2. Real-time PCR was used to quantify selected ≈200 base pair sequences of mtDNA within the COX1, ND1, and ND6 genes, as well as from the D-Loop transcriptional regulatory region. MODS was defined as a Denver Multiple Organ Failure score of 4 or greater. RESULTS: MtDNA DAMPs were quantified as PCR threshold cycle number. Lower threshold cycles indicate increased mtDNA DAMP content. Patients with SIRS had significantly increased mtDNA DAMP levels in all 4 sequences examined (32.14 ± 0.90 vs 29.00 ± 1.15 for COX1, 31.90 ± 0.47 vs 30.16 ± 1.42 for ND1, 32.40 ± 0.61 vs 28.94 ± 1.13 for ND6, and 33.12 ± 0.83 vs 28.30 ± 1.14 for D-Loop). Patients who developed MODS also had elevated mtDNA DAMP levels compared with those who did not (32.57 ± 0.74 vs 27.12 ± 0.66 for COX1, 32.45 ± 0.65 vs 28.20 ± 0.73 for ND1, 32.52 ± 0.56 vs 27.60 ± 0.79 for ND6, and 32.85 ± 0.75 vs 27.86 ± 1.27 for D-Loop). Patients with above-median mtDNA DAMP levels had a significantly elevated relative risk for mortality. Four patients died secondary to severe MODS. CONCLUSIONS: These findings comprise the first observational evidence that plasma mtDNA DAMPs is associated with the evolution of SIRS, MODS, and mortality in severely injured human subjects.

ABSTRACT

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.

ABSTRACT

BACKGROUND: Opioids remain the mainstay treatment of acute pain caused by trauma. The lack of evidence driven prescribing creates a challenging situation for providers. We hypothesized that the implementation of a trauma discharge opioid bundle (TDOB) would decrease the total morphine milligram equivalents (MME) prescribed at discharge while maintaining pain control. METHODS: This was a pre-post study of adult trauma patients before and after implementation of a TDOB to guide the prescription of opioids and discharge prescription education in patients discharged from a level one trauma center. The pre-group and post-group, included consecutively discharged patients from September through November in 2018 and 2019. The primary outcome was the total MME prescribed at discharge. RESULTS: A total of 377 patients met inclusion criteria. One hundred and fifty-one patients were included in the pre-group and 226 in the post-group. The total MME prescribed at discharge (225 ± [150-300] pre vs 200 ± [100-225] post, P = < .001) and maximum MME/day (45 ± [30-45] vs 30 ± [20-45], P = .004) were significantly less in the post-group. Incidence of outpatient refills within fourteen days were similar. More non-opioid pain adjuncts were prescribed post-intervention and discharge pain education was provided more frequently. CONCLUSION: The implementation of a TDOB significantly reduced the MME prescribed at discharge without increasing the number of opioid refills.

ABSTRACT

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).

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.
