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.

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.

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.

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.

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.

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.

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.

The Relationship between Serum Sodium, Serum Osmolality, and Intracranial Pressure in Patients with Traumatic Brain Injury Treated with Hyperosmolar Therapy.

BACKGROUND: Treatment of elevated intracranial pressure (ICP) in traumatic brain injury (TBI) is controversial. Hyperosmolar therapy is used to prevent cerebral edema in these patients. Many intensivists measure direct correlates of these agents-serum sodium and osmolality. We seek to provide context on the utility of using these measures to estimate ICP in TBI patients. MATERIALS AND METHODS: Patients admitted with TBI who required ICP monitoring from 2008 to 2012 were included. Intracranial pressure, serum sodium, and serum osmolality were assessed prior to hyperosmotic therapy then at 6, 12, 18, 24, 48, and 72 hours after admission. A linear regression was performed on sodium, osmolality, and ICP at baseline and serum sodium and osmolality that corresponded with ICP for 6-72-hour time points. RESULTS: 136 patients were identified. Patients with initial measures were included in the baseline analysis (n = 29). Patients who underwent a craniectomy were excluded from the 6-72-hour analysis (n = 53). Initial ICP and serum sodium were not significantly correlated (R2 .00367, P = .696). Initial ICP and serum osmolality were not significantly correlated (R2 .00734, P = .665). Intracranial pressure and serum sodium 6-72 hours after presentation were poorly correlated (R2 .104, P < .0001), as were ICP and serum osmolality at 6-72 hours after presentation (R2 .116, P < .0001). DISCUSSION: Our results indicate initial ICP is not correlated with serum sodium or osmolality suggesting these are not useful initial clinical markers for ICP estimation. The association between ICP and serum sodium and osmolality after hyperosmolar therapy was poor, thus may not be useful as surrogates for direct ICP measurements.

Potential contribution of mitochondrial DNA damage associated molecular patterns in transfusion products to the development of acute respiratory distress syndrome after multiple transfusions.

BACKGROUND: Massive transfusions are accompanied by an increased incidence of a particularly aggressive and lethal form of acute lung injury (delayed transfusion-related acute lung injury) which occurs longer than 24 hours after transfusions. In light of recent reports showing that mitochondrial (mt)DNA damage-associated molecular patterns (DAMPs) are potent proinflammatory mediators, and that their abundance in the sera of severely injured or septic patients is predictive of clinical outcomes, we explored the idea that mtDNA DAMPs are present in transfusion products and are associated with the occurrence of delayed transfusion-related acute lung injury. METHODS: We prospectively enrolled fourteen consecutive severely injured patients that received greater than three units of blood transfusion products and determined if the total amount of mtDNA DAMPs delivered during transfusion correlated with serum mtDNA DAMPs measured after the last transfusion, and whether the quantity of mtDNA DAMPs in the serum-predicted development of acute respiratory distress syndrome (ARDS). RESULTS: We found detectable levels of mtDNA DAMPs in packed red blood cells (3 ± 0.4 ng/mL), fresh frozen plasma (213.7 ± 65 ng/mL), and platelets (94.8 ± 69.2), with the latter two transfusion products containing significant amounts of mtDNA fragments. There was a linear relationship between the mtDNA DAMPs given during transfusion and the serum concentration of mtDNA fragments (R = 0.0.74, p < 0.01). The quantity of mtDNA DAMPs in serum measured at 24 hours after transfusion predicted the occurrence of ARDS (9.9 ± 1.4 vs. 3.3 ± 0.9, p < 0.01). CONCLUSION: These data show that fresh frozen plasma and platelets contain large amounts of extracellular mtDNA, that the amount of mtDNA DAMPs administered during transfusion may be a determinant of serum mtDNA DAMP levels, and that serum levels of mtDNA DAMPs after multiple transfusions may predict the development of ARDS. Collectively, these findings support the idea that mtDNA DAMPs in transfusion products significantly contribute to the incidence of ARDS after massive transfusions. LEVEL OF EVIDENCE: Prognostic study, level II; therapeutic study, level II.

Mitochondrial DNA damage associated molecular patterns in ventilator-associated pneumonia: Prevention and reversal by intratracheal DNase I.

BACKGROUND: Previous studies in isolated perfused rat lungs have revealed that endothelial barrier disruption after intratracheal administration of Pseudomonas aeruginosa (strain 103; PA103) only occurs after accumulation of extracellular mitochondrial DNA (mtDNA) damage-associated molecular patterns (DAMPs) in the perfusate and is suppressed by addition of DNase to the perfusion medium. Herein, we tested the hypothesis that intratracheal DNase-a route of administration readily translatable to patient with ventilator-associated pneumonia (VAP)-also enhances degradation of mtDNA and prevents bacteria-induced lung injury. METHODS: Intratracheal DNase was administered to isolated rat lungs either before or after intratracheal challenge with PA103 to determine if bacteria-induced mtDNA DAMP-dependent lung injury could be prevented or reversed by enhanced mtDNA degradation. To explore whether this concept is translatable to patients with VAP, consecutive patients suspected of VAP were prospectively enrolled. All patients suspected of VAP received a bronchoalveolar lavage (BAL) with quantitative culture for the diagnosis of VAP. Mitochondrial and nuclear DNAs were measured from the BAL. MtDNA DAMPs (i.e., ND6) were measured from serum at time of suspected diagnosis and at 24 to 48 hours afterward. RESULTS: Intratracheal PA103 caused significantly increased the vascular filtration coefficient (Kf) and perfusate mtDNA DAMPs. In contrast, lungs pretreated or posttreated with intratracheal DNase were protected from increases in Kf and mtDNA DAMPs. Patients with the diagnosis of VAP had significantly higher mtDNA DAMPs in the BAL (248.70 ± 109.7 vs. 43.91 ± 16.61, p < 0.05, respectively) and in the serum at 24 hours (159.60 ± 77.37 vs. 10.43 ± 4.36, p < 0.05; respectively) when compared with patients that did not have VAP. CONCLUSION: These findings in isolated perfused rat lungs and a cohort of severely injured patients reveal an association between bacterial pneumonia and accumulation of mtDNA DAMPs in the lung and serum. Furthermore, administration of intratracheal DNase I prevented and reversed pulmonary endothelial dysfunction evoked by PA103.

Evaluation of Microvascular Perfusion and Resuscitation after Severe Injury.

Achieving adequate perfusion is a key goal of treatment in severe trauma; however, tissue perfusion has classically been measured by indirect means. Direct visualization of capillary flow has been applied in sepsis, but application of this technology to the trauma population has been limited. The purpose of this investigation was to compare the efficacy of standard indirect measures of perfusion to direct imaging of the sublingual microcirculatory flow during trauma resuscitation. Patients with injury severity scores >15 were serially examined using a handheld sidestream dark-field video microscope. In addition, measurements were also made from healthy volunteers. The De Backer score, a morphometric capillary density score, and total vessel density (TVD) as cumulative vessel area within the image, were calculated using Automated Vascular Analysis (AVA3.0) software. These indices were compared against clinical and laboratory parameters of organ function and systemic metabolic status as well as mortality. Twenty severely injured patients had lower TVD (X = 14.6 ± 0.22 vs 17.66 ± 0.51) and De Backer scores (X = 9.62 ± 0.16 vs 11.55 ± 0.37) compared with healthy controls. These scores best correlated with serum lactate (TVD R(2) = 0.525, De Backer R(2) = 0.576, P < 0.05). Mean arterial pressure, heart rate, oxygen saturation, pH, bicarbonate, base deficit, hematocrit, and coagulation parameters correlated poorly with both TVD and De Backer score. Direct measurement of sublingual microvascular perfusion is technically feasible in trauma patients, and seems to provide real-time assessment of microcirculatory perfusion. This study suggests that in severe trauma, many indirect measurements of perfusion do not correlate with microvascular perfusion. However, visualized perfusion deficiencies do reflect a shift toward anaerobic metabolism.
