ABSTRACT

INTRODUCTION: Large animal-related injuries (LARI) are relatively uncommon, but, nevertheless, a public hazard. The objective of this study was to better understand LARI injury patterns and outcomes. MATERIALS AND METHODS: We performed a retrospective review of the 2016 National Trauma Data Bank and used ICD-10 codes to identify patients injured by a large animal. The primary outcome was severe injury pattern, while secondary outcomes included mortality, hospital length of stay, ICU admission, and mechanical ventilation usage. RESULTS: There were 6,662 LARI included in our analysis. Most LARI (66%) occurred while riding the animal, and the most common type of LARI was fall from horse (63%). The median ISS was 9 and the most severe injuries (AIS ≥ 3) were to the chest (19%), head (10%), and lower extremities (10%). The overall mortality was low at 0.8%. Compared to non-riders, riders sustained more severe injuries to the chest (21% vs. 16%, p<0.001) and spine (4% vs. 2%, p<0.001). Compared to motor vehicle collisions (MVC), riders sustained fewer severe injuries to the head (10% vs. 12%, p<0.001) and lower extremity (10% vs. 12%, p=0.01). Compared to auto-pedestrian accidents, non-riders sustained fewer severe injuries to the head (11% vs. 19%, p<0.001) and lower extremity (10% vs. 20%, p<0.001). CONCLUSION: Patients involved in a LARI are moderately injured with more complex injuries occurring in the chest, head, and lower extremities. Fall from horse was the most common LARI mechanism. Overall mortality was low. Compared to non-riders, riders were more likely to sustain severe injuries to the chest and spine. Severe injury patterns were similar when comparing riders to MVC and, given that most LARI are riding injuries, we recommend trauma teams approach LARI as they would an MVC.

ABSTRACT

BACKGROUND: We aimed to identify risk factors and risk scoring models to help identify post-traumatic pulmonary embolisms (PE). METHODS: We performed a retrospective review (2014-2019) of all adult trauma patients admitted to our Level I trauma center that received a CT pulmonary angiogram (CTPA) for a suspected PE. A systematic literature search found eleven risk scoring models, all of which were applied to these patients. Scores of patients with and without PE were compared. RESULTS: Of the 235 trauma patients that received CTPA, 31 (13%) showed a PE. No risk scoring model had both a sensitivity and specificity above 90%. The Wells Score had the highest area under the curve (0.65). After logistic regression, no risk scoring model variables were independently associated with PE. CONCLUSIONS: In trauma patients with clinically suspected PE, clinical variables and current risk scoring models do not adequately differentiate patients with and without PE.

ABSTRACT

BACKGROUND: Platelet dysfunction (PD) is an independent predictor of mortality in patients with severe traumatic brain injury (sTBI). Platelet transfusions (PLTs) have been shown to be an effective treatment strategy to reverse platelet inhibition. Their use is contingent on availability and may be associated with increased cost and transfusion-related complications, making desmopressin (DDAVP) attractive. We hypothesized that DDAVP would correct PD similarly to PLTs in patients with sTBI. METHODS: This retrospective study evaluated all blunt trauma patients admitted to an urban, level 1 trauma center from July 2015 to October 2016 with sTBI (defined as head abbreviated injury scale [AIS] ≥3) and PD (defined as adenosine diphosphate [ADP] inhibition ≥60% on thromboelastography) and subsequently received treatment. Per our institutional practice, patients with sTBI and PD are transfused one unit of apheresis platelets to reverse inhibition. During a platelet shortage, we interchanged DDAVP for the initial treatment. Patients were classified as receiving DDAVP or PLT based on the initial treatment. RESULTS: A total of 57 patients were included (DDAVP, n = 23; PLT, n = 34). Patients who received DDAVP were more severely injured (injury severity score, 29 vs. 23; p = 0.045), but there was no difference in head AIS (4 vs. 4, p = 0.16). There was no difference between the two groups in admission platelet count (244 ± 68 × 10/µL vs. 265 ± 66 × 10/µL, p = 0.24) or other coagulation parameters such as prothrombin time, partial thromboplastin time, or international normalized ratio. Before treatment, both groups had similar ADP inhibition as measured by thromboelastography (ADP, 86% vs. 89%, p = 0.34). After treatment, both the DDAVP and PLT groups had similar correction of platelet ADP inhibition (p = 0.28). CONCLUSION: In patients with severe traumatic brain injury and PD, DDAVP may be an alternative to PLTs to correct PD. LEVEL OF EVIDENCE: Therapeutic, level IV.

ABSTRACT

BACKGROUND: Platelet dysfunction, defined as adenosine diphosphate inhibition greater than 60% on thromboelastogram, is an independent predictor of increased mortality in patients with severe traumatic brain injury (TBI). We changed our practice to transfuse platelets for all patients with severe TBI and platelet dysfunction. We hypothesized that platelet transfusions would correct platelet dysfunction and improve mortality in patients with severe TBI. METHODS: This retrospective review included adult trauma patients admitted to our Level I trauma center from July 2015 to October 2016 with severe TBI (head Abbreviated Injury Scale score ≥ 3) who presented with platelet dysfunction and subsequently received a platelet transfusion. Serial thromboelastograms were obtained to characterize the impact of platelet transfusion on clot strength. Subsequently, the platelet transfusion group was compared to a group of historical controls with severe TBI patients and platelet dysfunction who did not receive platelet transfusion. RESULTS: A total of 35 patients with severe TBI presented with platelet dysfunction. Following platelet transfusion clot strength improved as represented by decreased K time, increased α angle, maximum amplitude, and G-value, as well as correction of adenosine diphosphate inhibition. When comparing to 51 historic controls with severe TBI and platelet dysfunction, the 35 study patients who received a platelet transfusion had a lower mortality (9% vs. 35%; p = 0.005). In stepwise logistic regression, platelet transfusion was independently associated with decreased mortality (odds ratio, 0.23; 95% confidence interval, 0.06-0.92; p = 0.038). CONCLUSION: In patients with severe TBI and platelet dysfunction, platelet transfusions correct platelet inhibition and may be associated with decreased mortality. LEVEL OF EVIDENCE: Therapeutic, level II.

ABSTRACT

Acute respiratory distress syndrome (ARDS) is a complex inflammatory process with multifactorial etiologies. Risk factors for its development have been extensively studied, but factors associated with worsening severity of disease, as defined by the Berlin criteria, are poorly understood. A retrospective chart and trauma registry review identified trauma patients in our surgical intensive care unit who developed ARDS, defined according to the Berlin definition, between 2010 and 2015. The primary outcome was development of mild, moderate, or severe ARDS. A logistic regression model identified risk factors associated with developing ARDS and with worsening severity of disease. Of 2704 total patients, 432 (16%) developed ARDS. Of those, 100 (23%) were categorized as mild, 176 (41%) as moderate, and 156 (36%) as severe. Two thousand two hundred and seventy-two patients who did not develop ARDS served as controls. Male gender, blunt trauma, severe head and chest injuries, and red blood cell as well as total blood product transfusions are independent risk factors associated with ARDS. Worsening severity of disease is associated with severe chest trauma and volume of plasma transfusion. Novel findings in our study include the association between plasma transfusions and specifically severe chest trauma with worsening severity of ARDS in trauma patients.

ABSTRACT

BACKGROUND: Catheter-associated urinary tract infections (CAUTIs) are common nosocomial infections. In 2015, the Centers for Medicare and Medicaid Services began imposing financial penalties for institutions where CAUTI rates are higher than predicted. However, the surveillance definition for CAUTI is not a clinical diagnosis and may represent asymptomatic bacteriuria. The objective of this study was to compare rates of urinary catheterization and CAUTI before and after the implementation of a bundled intervention. METHODS: This retrospective review evaluated trauma patients from January 2013-January 2015. The bundled intervention optimized the urinary catheterization process and culturing practices to reduce false positives. The CAUTI rate was defined as a positive surveillance CAUTI divided by total catheter days multiplied by 1,000 days. RESULTS: A total of 6,236 patients were included (pre: n = 5,003; post: n = 1,233). Fewer patients in the post bundle group received a urinary catheter (pre: 25% vs post: 16%; P < .001). After bundle implementation, the CAUTI rate reduced over one third (pre: 4.07 vs post: 2.56; incidence rate ratio, 0.63; 95% confidence interval, 0.19-2.07). CONCLUSIONS: Although the number of patients exposed to urinary catheters and catheter days was decreased, optimization of culturing practices was essential to prevent the CAUTI rate from increasing from a reduced denominator. Implementation of a CAUTI prevention bundle works synergistically to improve patient safety and hospital performance.

ABSTRACT

Consent and conversion rates of potential organ donors in the United States need to be maximized to match the number of individuals awaiting organ donation. Studies to date have not focused on characteristics of centers with better outcomes. We performed an 8-year (2006-2014) retrospective study of our local organ procurement organization database. We categorized hospitals in our region as academic centers versus nonacademic centers, trauma centers versus nontrauma centers, and large (≥400 beds) centers versus small (<400 beds) centers. We also compared trauma centers with Level I designation to all other centers. Primary outcomes included consent and conversion rates for potential organ donors. There were 22,732 referrals to our organ procurement organization that resulted in 1,057 eligible deaths. When comparing academic to nonacademic hospitals, academic hospitals had higher consent (71% vs 59%, P < 0.0001) and conversion (73% vs 64%, P = 0.008) rates. Level I trauma centers had better consent and conversion rates when compared to all other hospitals, 73 versus 55 per cent and 76 versus 61 per cent respectively, P < 0.0001 for both. The small, academic, trauma centers had the highest consent and conversion rates, 77 and 78 per cent, respectively, P < 0.0001 for both. Hospital characteristics such as academic involvement, Level I trauma designation, and size impact consent and conversion rates for potential organ donors. Small (<400 bed), academic, trauma centers have the highest consent rates and conversion rates. Factors for success in these institutions should be examined and applied to assist in improving donor rates across all types of hospitals.

ABSTRACT

PURPOSE: Thromboelastography (TEG) has been recommended to characterize post-traumatic coagulopathy, yet no study has evaluated the impact of pre-injury anticoagulation (AC) on TEG variables. We hypothesized patients on pre-injury AC have a greater incidence of coagulopathy on TEG compared to those without AC. METHODS: This retrospective chart review evaluated all trauma patients admitted to an urban, level one trauma center from February 2011 to September 2014 who received a TEG within the first 24h. Patients were classified as receiving pre-injury AC or no AC if their documented medications prior to admission included warfarin, dabigatran, or anti-Xa (aXa) inhibitors (apixaban or rivaroxaban). The presence of coagulopathy on TEG or conventional assays was defined by exceeding local laboratory reference standards. RESULTS: A total of 54 patients were included (AC, n=27 [warfarin n=13, dabigatran n=6, aXa inhibitor n=8] vs. no AC, n=27). Baseline characteristics were similar between groups, including age (72±13years vs. 72±15; p=0.85), male gender (70% vs. 74%; p=0.76) and blunt mechanism of injury (100% vs. 100%; p=1). There was no difference in the number of patients determined to have coagulopathy on TEG (no AC 11% vs. AC 15%; p=0.99). Conventional tests, including the international normalized ratio (INR) and activated partial thromboplastin time (aPTT), identified coagulopathy in a high proportion of anti-coagulated patients (no AC 22% vs. AC 85%; p<0.01). CONCLUSION: TEG has limited clinical utility to evaluate the presence of pre-injury AC. Traditional markers of drug induced coagulopathy should guide reversal decisions.

ABSTRACT

BACKGROUND: Post Traumatic Stress Disorder (PTSD) has become a focus for the care of trauma victims, but the incidence of PTSD in those who care for injured patients has not been well studied. Our hypothesis was that a significant proportion of health care providers involved with trauma care are at risk of developing PTSD. METHODS: A system-wide survey was applied using a modified version of the Primary Care PTSD Screen [PC-PTSD], a validated PTSD screening tool currently being used by the VA to screen veterans for PTSD. Pre-hospital and in-hospital care providers including paramedics, nurses, trauma surgeons, emergency medicine physicians, and residents were invited to participate in the survey. The survey questionnaire was anonymously and voluntarily performed online using the Qualtrix system. Providers screened positive if they affirmatively answered any three or more of the four screening questions and negative if they answered less than three questions with a positive answer. Respondents were grouped by age, gender, region, and profession. RESULTS: 546 providers answered all of the survey questions. The screening was positive in 180 (33%) and negative in 366 (67%) of the responders. There were no differences observed in screen positivity for gender, region, or age. Pre-hospital providers were significantly more likely to screen positive for PTSD compared to the in-hospital providers (42% vs. 21%, P<0.001). Only 55% of respondents had ever received any information or education about PTSD and only 13% of respondents ever sought treatment for PTSD. CONCLUSION: The results of this survey are alarming, with high proportions of healthcare workers at risk for PTSD across all professional groups. PTSD is a vastly underreported entity in those who care for the injured and could potentially represent a major problem for both pre-hospital and in-hospital providers. A larger, national study is warranted to verify these regional results.

ABSTRACT

Thromboelastography (TEG) with platelet mapping has been proposed as an assay to detect the presence of antiplatelet agents (APA), yet no study has evaluated TEG markers of platelet dysfunction in acute trauma patients stratified by the use of preinjury APA. We hypothesized that patients on preinjury APA would demonstrate prolonged TEG markers of platelet dysfunction compared with those not on preinjury APA. This retrospective review evaluated all trauma patients admitted to a Level I trauma center from February 2011 to April 2013 who received a TEG within the first 24 hours of admission. Patients were classified as receiving preinjury APA or no APA if their documented medications included either aspirin or adenosine diphosphate (ADP) antagonists, including clopidogrel, prasugrel, and ticagrelor. A total of 129 patients were included (APA, n = 35; no APA n = 94) in the study. The time from admission to the first TEG was similar (APA 175 ± 289 minutes versus no APA 216 ± 321 minutes, P = 0.5). There was no significant difference in TEG markers of platelet dysfunction, including per cent ADP inhibition (APA 61.7 ± 25.8% versus no APA 62.3 ± 28.8%; P = 0.91) or per cent arachidonic acid inhibition (APA 58.2 ± 31% versus no APA 53.8 ± 34%; P = 0.54). Both groups had similar proportion of severe platelet dysfunction, defined as ADP inhibition greater than 70 per cent (APA 40% versus no APA 40%; P = 0.8) and arachidonic acid inhibition greater than 70 per cent (APA 40% versus no APA 39%; P = 0.89). In conclusion, platelet dysfunction after major trauma is common. Therefore, TEG alone should not be used to evaluate for the presence of APA due to apparent lack of specificity.

ABSTRACT

BACKGROUND: Magnetic resonance cholangiopancreatography (MRCP) is believed to be a useful tool to evaluate the biliary tree and pancreas for stones, tumors, or injuries to the ductile system. The purpose of this study was to compare the accuracy of MRCP to the gold standard, endoscopic retrograde cholangiopancreatography (ERCP), in our institution. STUDY DESIGN: We performed a retrospective review of all MRCP followed by ERCP (follow-on ERCP) at a single institution over a 6-year period. Exam findings from MRCP were compared with findings on the follow-on ERCP and compared. Studies were grouped into 2 main classifications: tests being performed for patients with suspected choledocholithiasis (stone disease) and tests being performed for concerns of malignant strictures or duct injuries (non-stone disease). RESULTS: A total of 81 patients had MRCPs and follow-on ERCPs in this time period. Thirty-six patients had positive findings on MRCP and ERCP for stones in the common duct system, and 14 patients had positive findings on MRCP and subsequent ERCP for masses and strictures of the common duct. Three patients had positive MRCP and ERCP findings for pancreatic duct abnormalities. The specificity and positive predictive value of MRCP were 94% and 98%, respectively. However, 13 of 28 patients had lesions identified on ERCP after a normal MRCP. The sensitivity and negative predictive value were 80% and 54%, respectively. CONCLUSIONS: Magnetic resonance cholangiopancreatography was not useful in the management algorithm of either stone or non-stone disease of the biliary tree or pancreas. It should be abandoned as a diagnostic tool for work-up of biliary duct pathology.

ABSTRACT

BACKGROUND: Occult pneumothorax (OPTX) represents air within the pleural space not visible on conventional chest radiographs. Increased use of computed tomography has led to a rise in the detection of OPTX. Optimal management remains undefined. METHODS: A pediatric subgroup analysis (age <18 years) from a multicenter, observational study evaluating OPTX management. Data analyzed were pneumothorax size, management outcome, and associated risk factors to characterize those that may be safely observed. RESULTS: Fifty-two OPTX (7.3 ± 6.2 mm) in 51 patients were identified. None were greater than 27 mm; all those under 16.5 mm (n = 48) were successfully managed without intervention. Two patients underwent initial tube thoracostomy (one [21 mm] and the other with bilateral OPTX [24 mm, 27 mm]). Among patients under observation (n = 49), OPTX size progressed in 2; one (6.4mm) required no treatment, while one (16.5 mm) received elective intervention. Respiratory distress occurred in one patient (10.7 mm) who did not require tube thoracostomy. Nine received positive pressure ventilation; 8 did not have a tube thoracostomy. Twenty-four patients (51%) had one or more rib fractures; 3 required tube thoracostomy. CONCLUSION: No pediatric OPTX initially observed developed a tension pneumothorax or adverse event related to observation. Pediatric patients with OPTX less than 16 mm may be safely observed. Neither the presence of rib fractures nor need for PPV alone necessitates intervention.

ABSTRACT

BACKGROUND: An occult pneumothorax (OPTX) is found incidentally in 2% to 10% of all blunt trauma patients. Indications for intervention remain controversial. We sought to determine which factors predicted failed observation in blunt trauma patients. METHODS: A prospective, observational, multicenter study was undertaken to identify patients with OPTX. Successfully observed patients and patients who failed observation were compared. Multivariate logistic regression was used to identify predictors of failure of observation. OPTX size was calculated by measuring the largest air collection along a line perpendicular from the chest wall to the lung or mediastinum. RESULTS: Sixteen trauma centers identified 588 OPTXs in 569 blunt trauma patients. One hundred twenty-one patients (21%) underwent immediate tube thoracostomy and 448 (79%) were observed. Twenty-seven patients (6%) failed observation and required tube thoracostomy for OPTX progression, respiratory distress, or subsequent hemothorax. Fourteen percent (10 of 73) failed observation during positive pressure ventilation. Hospital and intensive care unit lengths of stay, and ventilator days were longer in the failed observation group. OPTX progression and respiratory distress were significant predictors of failed observation. Most patient deaths were from traumatic brain injury. Fifteen percentage of patients in the failed observation group developed complications. No patient who failed observation developed a tension PTX, or experienced adverse events by delaying tube thoracostomy. CONCLUSION: Most blunt trauma patients with OPTX can be carefully monitored without tube thoracostomy; however, OPTX progression and respiratory distress are independently associated with observation failure.
