Introduction Protective devices such as seat belts and helmets save lives. Most studies only address one aspect of the injury profile – compliance or mortality – not the entire spectrum of trauma care, and little attention is paid to racial differences in the use or impact of protective devices. Methods Patients with blunt mechanisms where using protective devices would be expected were included and were divided into utilizing (P) vs not utilizing protection (Non-P). Chart review included demographics, injuries sustained, hemodynamics, and blood alcohol level. Outcomes included need for emergent operation, complications and death. Results Non-P patients were more likely male, presented at night and intoxicated. Highest risk behavior (intoxicated Non-P) presented at night (25.7% of nighttime presentations), and rarely during daytime (6.7% daytime presentations). Non-P were more likely hypotensive and sustain a traumatic brain injury. No race related differences were noted among young patients. Among older (>/=50 years) patients, White patients were least likely Non-P and least likely presented at night. Non-P required more emergent operative intervention, ICU admission, and longer hospital stay. Overall, Non-P was associated with increased risk of death (OR = 1.6 (95% CI = 1.28 – 2.11). Conclusion Given unique age and racial differences, we advocate for culturally and age specific public service campaigns.

National regulations to curb the coronavirus disease 2019 (COVID-19) transmission and health care resource reallocation may have impacted incidence and treatment for neurotrauma, including traumatic brain injury (TBI) and spinal trauma, but these trends have not been characterized in Sub-Saharan Africa. This study analyzes differences in epidemiology, management, and outcomes preceding and during the COVID-19 pandemic for neurotrauma patients in a Rwandan tertiary hospital. The study setting was the Centre Hospitalier Universitaire de Kigali (CHUK), Rwanda's national referral hospital. Adult injury patients presenting to the CHUK Emergency Department (ED) were prospectively enrolled from January 27, 2020 to June 28, 2020. Study personnel collected data on demographics, injury characteristics, serial neurological examinations, treatment, and outcomes. Differences in patients before (January 27, 2020 to March 21, 2020) and during (June 1, 2020 to June 28, 2020) the COVID-19 pandemic were assessed using chi-squared and Mann-Whitney

Early administration of tranexamic acid (TXA) has been widely implemented for the treatment of presumed hyperfibrinolysis in hemorrhagic shock. We aimed to characterize the liberal use of TXA and whether unjustified administration was associated with increased venous thrombotic events (VTEs).We identified injured patients who received TXA between January 2016 and January 2018 by querying our Level 1 trauma center's registry. We retrospectively reviewed medical records and radiologic images to classify whether patients had a hemorrhagic injury that would have benefited from TXA (justified) or not (unjustified).Ninety-five patients received TXA for traumatic injuries, 42.1% were given by emergency medical services. TXA was considered unjustified in 35.8% of the patients retrospectively and in 52% of the patients when given by emergency medical services. Compared with unjustified administration, patients in the justified group were younger (47.6 versus 58.4; P = 0.02), more hypotensive in the field (systolic blood pressure: 107 ± 31 versus 137 ± 32 mm Hg; P 0.001) and in the emergency department (systolic blood pressure: 97 ± 27 versus 128 ± 27; P 0.001), and more tachycardic in emergency department (heart rate: 99 ± 29 versus 88 ± 19; P = 0.04). The justified group also had higher injury severity score (median 24 versus 11; P 0.001), was transfused more often (81.7% versus 20.6%; P 0.001), and had higher in-hospital mortality (39.3% versus 2.9%; P 0.001), but there was no difference in the rate of VTE (8.2% versus 5.9%).Our results highlight a high rate of unjustified administration, especially in the prehospital setting. Hypotension and tachycardia were indications of correct use. Although we did not observe a difference in VTE rates between the groups, though, our study was underpowered to detect a difference. Cautious implementation of TXA in resuscitation protocols is encouraged in the meantime. Nonetheless, adverse events associated with unjustified TXA administration should be further evaluated.

Injured patients benefit from direct transport to a trauma center; however, it is unknown whether patients with traumatic out-of-hospital cardiac arrest (OHCA) benefit from initial resuscitation at the nearest emergency department (ED) if a trauma center is farther away. We hypothesized that patients with traumatic OHCA transported directly to a trauma center have less in-hospital mortality after initial resuscitation compared to those transferred from non-trauma centers.We examined patients presenting with traumatic OHCA within our institutional trauma registry and the National Trauma Data Bank (NTDB) and excluded patients with ED mortality. Our primary outcome was all-cause mortality during index hospitalization; multiple logistic regression controlled for age, sex, injury severity score, mechanism of injury, signs of life, emergency surgery, and level I trauma center designation.We identified 271 and 1,138 adult patients with traumatic OHCA in our registry and the NTDB; 28% and 16% were transferred from another facility, respectively. Following initial resuscitation, patients transferred to a trauma center had higher in-hospital mortality than those transported directly in both our local and national cohorts (aOR: 2.27, 95%CI: 1.03-4.98, and aOR: 2.66, 95%CI: 1.35 - 5.26, respectively).Patients with traumatic OHCA transported directly to a trauma center may have increased survival to discharge compared to those transferred from another facility, even accounting for initial resuscitation. Further investigation should examine the impact of both physiologic and logistic factors including distance to trauma center, traffic, and weather patterns that may impact prehospital decision-making and destination selection.

Early identification of traumatic brain injury (TBI) with head CT HCT should expedite operative decision-making and improve outcome. We aimed to determine whether an early HCT protocol in TBI patients would improve outcome.A multidisciplinary protocol to obtain an HCT within 30 minutes from arrival for patients with GCS ≤ 13 was instituted on 1/1/2015. Our trauma registry was queried for patients evaluated between 3/2012 and 12/2015. Outcomes included compliance with protocol and in-hospital mortality.346 patients presented with GCS ≤ 13. Patients PRE- (n=264) and POST-protocol (n=82) were similar in demographic and physiologic characteristics. Time to HCT was lower (35 vs. 77 min; p0.001). POST-protocol had lower odds of mortality (OR 0.65, 95% CI 0.43-0.99) adjusting for age, gender, ISS and GCS.Implementing a protocol of early HCT for TBI optimized performance of the trauma team. Time to HCT could serve as a quality metric in TBI.

Background: Trauma increases the risk for infection, but it is unknown how infection affects goals-of-care (GOC) decision making. We sought to determine how infections impact transition to comfort ...

Use of anticoagulant and antiplatelet medications (AAMs) is increasing significantly with our growing population of older adults. AAMs worsen outcomes in trauma patients. Our goal was to improve collaboration between trauma and outpatient providers and to improve safety in making decisions on anticoagulant and antiplatelet medications(AAMs) after injuries.A risk management initiative.Patients that suffered traumatic injury while on anticoagulation or antiplatelets medications at a level I university trauma center.IRB approval was obtained to review records for medications, demographics, mechanism and type of injury, and indication for preinjury AAM use. Inpatient trauma team providers contacted the primary prescriber. A collaborative decision was made regarding AAM plans.One hundred and five patients, mean age 79 years, were followed. The three most common AAMs were warfarin (69 patients), clopidogrel (24), and Factor Xa inhibitors (16). Atrial fibrillation was the most common indication for AAMs (70 patients), venous thrombosis (14) and TIA/CVA (11). Falls were the most frequent injury mechanism, 79.4%. Soft tissue hematomas (27.4%), TBI (16%), and pelvic fractures (12.3%) were the most common injuries. In 56.6% AAMs were held until follow-up, 31.1% had AAMs resumed at discharge, and AAMs were held indefinitely in 12.3%. Patients discharged to home versus facility (37 vs 18% p0.05),75 years of age (47 vs 27% p0.05) were more likely to have AAMs resumed at discharge. Patients who suffered falls versus MVC mechanism were less likely to have AAMs resumed at discharge (28 vs 82% p0.05). CHA2DS2-VASc scores were similar between decision groups.This is the first description of mandatory communication between trauma and outpatient providers to guide decision making on AAMs after injury. Efforts should be made to determine if this mitigates risk by following patients longterm. This communication should become standard for a population that is often elderly, frail, and at risk of repeat injuries.

Introduction: While trauma prognostication and triage scores have been designed for use in lower-resourced healthcare settings specifically, the comparative clinical performance between trauma-specific and general triage scores for risk-stratifying injured patients in such settings is not well understood. This study evaluated the Kampala Trauma Score (KTS), Revised Trauma Score (RTS), and Triage Early Warning Score (TEWS) for accuracy in predicting mortality among injured patients seeking emergency department (ED) care at the Centre Hospitalier Universitaire de Kigali (CHUK) in Rwanda. Methods: A retrospective, randomly sampled cohort of ED patients presenting with injury was accrued from August 2015–July 2016. Primary outcome was 14-day mortality and secondary outcome was overall facility-based mortality. We evaluated summary statistics of the cohort. Bootstrap regression models were used to compare areas under receiver operating curves (AUC) with associated 95% confidence intervals (CI). Results: Among 617 cases, the median age was 32 years and 73.5% were male. The most frequent mechanism of injury was road traffic incident (56.2%). Predominant anatomical regions of injury were craniofacial (39.3%) and lower extremities (38.7%), and the most common injury types were fracture (46.0%) and contusion (12.0%). Fourteen-day mortality was 2.6% and overall facility-based mortality was 3.4%. For 14-day mortality, TEWS had the highest accuracy (AUC = 0.88, 95% CI, 0.76–1.00), followed by RTS (AUC = 0.73, 95% CI, 0.55–0.92), and then KTS (AUC = 0.65, 95% CI, 0.47–0.84). Similarly, for facility-based mortality, TEWS (AUC = 0.89, 95% CI, 0.79–0.98) had greater accuracy than RTS (AUC = 0.76, 95% CI, 0.61–0.91) and KTS (AUC = 0.68, 95% CI, 0.53–0.83). On pairwise comparisons, RTS had greater prognostic accuracy than KTS for 14-day mortality (P = 0.011) and TEWS had greater accuracy than KTS for overall (P = 0.007) mortality. However, TEWS and RTS accuracy were not significantly different for 14-day mortality (P = 0.864) or facility-based mortality (P = 0.101). Conclusion: In this cohort of emergently injured patients in Rwanda, the TEWS demonstrated the greatest accuracy for predicting mortality outcomes, with no significant discriminatory benefit found in the use of the trauma-specific RTS or KTS instruments, suggesting that the TEWS is the most clinically useful approach in the setting studied and likely in other similar ED environments.

Background: Rates of infections with multi-drug-resistant organisms (MDROs) are increasing among critically ill patients. Among non-surgical patients, MDROs increase directly the risk of adverse secondary events including death. However, similar effects do not appear to occur among surgical patients. Specifically, among critically injured trauma patients, it is unknown whether degree of injury versus the presence of an MDRO increases the risk of death. Methods: This is a retrospective chart review of admitted adult trauma patients. Data included demographics, medical comorbidities, injury severity score, infections, occurrence of pneumonia including microbiology sensitivity profile, hospital course, and outcomes. Results: Patients requiring adminission to the intensive care unit (ICU) were more severely injured with greater degree of thoracic and head trauma and had a greater burden of pre-trauma medical comorbidities. Among those admitted to the ICU, 93 patients developed pneumonia. Patients who developed pneumonia were younger and more severely injured, with higher rates of thoracic and head injuries and higher rates of smoking. Development of pneumonia was associated with worse outcomes. However, among patients with pneumonia, comparing MDRO to pan-sensitive (PanSens) infections, PanSens infection occurred earlier and were more likely associated with pre-trauma smoking status. There was no difference in injury patterns, medical comorbidities, or outcomes. Conclusion: The development of pneumonia among trauma patients reflects degree of injury and underlying medical status. However, development of MDRO versus PanSens pneumonia did not affect trauma-related outcomes further. This information will guide family discussions and critical care decisions better among vulnerable trauma patients.

Background: The greatest burden of sepsis- and septic shock-related morbidity and mortality is in low- and middle-income countries (LMICs). Accurate tracking of incidence and outcomes of patients in LMICs with sepsis has been limited by changing definitions, lack of diagnosis coding and health records, and deficits in personnel. Improving sepsis care in LMICs requires studying outcomes prospectively so that setting appropriate definitions, scoring systems, and treatment guidelines can be created. Our goal is to review the burden of sepsis and septic shock in LMICs, the evolution and applicability of definitions to LMICs, and management. Methods: The literature was searched through PubMed using a Boolean approach and the following terms: sepsis, septic shock, low- and middle-income countries. Articles were read by the authors and relevant information was abstracted and included with citations to create a narrative review. Results: The estimated worldwide incidence of sepsis admissions is 31.5 million cases per year leading to 5.3 million deaths. The World Health Organization (WHO) has urged LMICs to establish sepsis prevalence and outcomes. Most authors and societies involved in creating sepsis and septic shock definitions have been from high-income countries (HICs). Applicability of sepsis definitions in LMICs is uncertain. Quick-Sequential Organ Failure Assessment (qSOFA) and universal vital assessment (UVA) are useful screening and triage tools in LMICs because they can be done at the bedside. The key tenets of management of sepsis and septic shock in LMICs include early fluid resuscitation and antibiotic therapy coupled with source control when there is a surgical process. Surgical causes of sepsis should be identified rapidly. Scaling up surgical capacity in LMICs is an important step to improve source control of sepsis. Conclusion: Management guidelines specific to LMICs for sepsis and septic shock need to be refined further and studied prospectively. Improving access to surgery will improve outcomes of surgical cases of sepsis.

Context: Current protocols for the management of abdominal stab wounds were established based on retrospective data from prior decades. Few have investigated whether higher body mass index (BMI) affects outcomes after these injuries. Aim: The aim was to determine the effects of obesity on outcomes in abdominal stab wound patients. Setting and Design: This was a retrospective cohort study at a Level I university-associated trauma center in the United States. Materials and Methods: We reviewed medical records of 100 adult patients admitted to our trauma center with abdominal stab wounds. Demographics, types of internal organ injury, gastrointestinal (GI) resection and repair, mortality, length of hospital stay (LOS), units of blood transfused within 24 h of admission, need and indications for exploratory laparotomy, surgical site infections (SSI), and need for re-operation were compared between obese and nonobese patients. Statistical Analysis: Categorical and continuous outcome variables were compared between the two groups using Chi-squared and independent-samples t-tests, respectively. BMI was evaluated as a predictor of outcomes using univariate and multivariate logistic regression. Results: Records of 100 adult abdominal stab wound patients were reviewed. Twenty-five patients were obese. The obese group was older (38.76 vs. 31.23, P = 0.018). Rates of therapeutic laparotomy were similar between obese and nonobese patients (20 [80.00%] vs. 64 [85.33%]). Obesity was associated with longer LOS (9.6 vs. 6.5, P = 0.026). In the multivariate analysis, increasing BMI was an independent predictor of need for GI resection (odds ratio: 1.10 [1.02–1.18], P = 0.018). One patient from the obese group died. Conclusions: Obese patients with abdominal stab wounds have longer LOS than nonobese patients. Increasing BMI was an independent predictor of need for GI resection.

Background Worldwide, injuries account for approximately five million mortalities annually, with 90% occurring in low- and middle-income countries (LMICs). Although guidelines characterizing data for blood product transfusion in injury resuscitation have been established for high-income countries (HICs), no such information on use of blood products in LMICs exists. This systematic review evaluated the available literature on the use and associated outcomes of blood product transfusion therapies in LMICs for acute care of patients with injuries. Methods A systematic search of PubMed, EMBASE, Global Health, CINAHL and Cochrane databases through November 2018 was performed by a health sciences medical librarian. Prospective and cross-sectional reports of injured patients from LMICs involving data on blood product transfusion therapies were included. Two reviewers identified eligible records (κ=0.92); quality was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Report elements, patient characteristics, injury information, blood transfusion therapies provided and mortality outcomes were extracted and analyzed. Results Of 3411 records, 150 full-text reports were reviewed and 17 met inclusion criteria. Identified reports came from the World Health Organization regions of Africa, the Eastern Mediterranean, and South-East Asia. A total of 6535 patients were studied, with the majority from exclusively inpatient hospital settings (52.9%). Data on transfusion therapies demonstrated that packed red blood cells were given to 27.0% of patients, fresh frozen plasma to 13.8%, and unspecified product types to 50.1%. Among patients with blunt and penetrating injuries, 5.8% and 15.7% were treated with blood product transfusions, respectively. Four reports provided data on comparative mortality outcomes, of which two found higher mortality in blood transfusion-treated patients than in untreated patients at 17.4% and 30.4%. The overall quality of evidence was either low (52.9%) or very low (41.2%), with one report of moderate quality by GRADE criteria. Conclusion There is a paucity of high-quality data to inform appropriate use of blood transfusion therapies in LMIC injury care. Studies were geographically limited and did not include sufficient data on types of therapies and specific injury patterns treated. Future research in more diverse LMIC settings with improved data collection methods is needed to inform injury care globally.

The 80h work week has raised concerns that complications may increase due to multiple sign-outs or poor communication. Trauma Surgery manages complex trauma and acute care surgical patients with rapidly changing physiology, clinical demands and a large volume of data that must be communicated to render safe, effective patient care. Trauma Morning Report format may offer the ideal situation to study and teach sign-outs and resident communication.Surgery Residents were assessed on a 1-5 scale for their ability to communicate to their fellow residents. This consisted of 10 critical points of the presentation, treatment and workup from the previous night's trauma admissions. Scores were grouped into three areas. Each area was scored out of 15. Area 1 consisted of Initial patient presentation. Area 2 consisted of events in the trauma bay. Area 3 assessed clarity of language and ability to communicate to their fellow residents. The residents were assessed for inclusion of pertinent positive and negative findings, as well as overall clarity of communication. In phase 1, residents were unaware of the evaluation process. Phase 2 followed a series of resident education session about effective communication, sign-out techniques and delineation of evaluation criteria. Phase 3 was a resident-blinded phase which evaluated the sustainability of the improvements in resident communication.50 patient presentations in phase 1, 200 in phase 2, and 50 presentations in phase 3 were evaluated. Comparisons were made between the Phase 1 and Phase 2 evaluations. Area 1 (initial events) improved from 6.18 to 12.4 out of 15 (p0.0001). Area 2 (events in the trauma bay) improved from 9.78 to 16.53 (p0.0077). Area 3 (communication and language) improved from 8.36 to 12.22 out of 15 (P0.001). Phase 2 to Phase 3 evaluations were similar, showing no deterioration of skills.Trauma Surgery manages complex surgical patients, with rapidly changing physiologic and clinical demands. Trauma Morning Report, with diverse attendance including surgical attendings and residents in various training years, is the ideal venue for real-time teaching and evaluation of sign-outs and reinforcing good communication skills in residents.

Necrotizing soft tissue infection (NSTI) is a rapidly progressive infection characterized by tissue necrosis, septic shock, and is associated with a high risk of death. Key aspects of successful treatment include early recognition and emergent surgical source control. Necrotizing soft tissue infection may occur from a range of etiologies but may also occur rarely from gastrointestinal routes. We report a case of severe lumbar NSTI arising from an ileal pouch fistula in a patient with inflammatory bowel disease. We report a case of a 62-year-old male with a history of ulcerative colitis and restorative proctocolectomy who presented with a severe NSTI of the lumbar region.Our operative approach focused on debridement of infected necrotic tissue and abscess drainage to achieve source control. We elected to forego a transabdominal approach during the initial operation given that source control but not source elimination was deemed the initial priority.The patient subsequently underwent a diverting ileostomy and pouch salvage. After a prolonged hospital course, the patient recovered well.Fistulization from the gastrointestinal tract is a rare but potential source of NSTI. It is not necessary to address the fistula during the initial operation but should be done promptly after the patient stabilizes. Prompt surgical debridement of infected soft tissue as source control remains the cornerstone of the index operation.

Background: The burden of surgical infections in low- and middle-income countries (LMICs) remains poorly defined compared with high-income countries. Although there are common infections necessitating surgery prevalent across the world, such as appendicitis and peptic ulcer disease, other conditions are more localized geographically. To date, comprehensive assessment of the burden of surgically treatable infections or sequelae of surgical infections in LMICs is lacking. Methods: We reviewed the literature to define the burden of surgical infections in LMICs and characterize the needs and challenges of addressing this issue. Results: Surgical infections comprise a broad range of diseases including intra-abdominal, skin and soft tissue, and healthcare-associated infections and other infectious processes. Treatment of surgical infections requires a functional surgical ecosystem, microbiology services, and appropriate and effective antimicrobial therapy. Systems must be developed and maintained to evaluate screening, prevention, and treatment strategies. Solutions and interventions are proposed focusing on reducing the burden of disease, improving surveillance, strengthening antibiotic stewardship, and enhancing the management of surgical infections. Conclusions: Surgical infections constitute a large burden of disease globally. Challenges to management in LMICs include a shortage of trained personnel and material resources. The increasing rate of antimicrobial drug resistance, likely related to antibiotic misuse, adds to the challenges. Development of surveillance, infection prevention, and antimicrobial stewardship programs are initial steps forward. Education is critical and should begin early in training, be an active process, and be sustained through regular programs.

Penetrating self-inflicted injury is a mechanism that occurs with significant frequency at many trauma centers in the United States and internationally. With high rates of unemployment and growing numbers of individuals with mental illness, we expect more and more patients to present with these injuries. Additionally, there are known to be misconceptions about the seriousness of injuries that can occur when penetrating trauma is self-inflicted, especially with stab wounds. There is also often uncertainty among surgeons regarding how to treat these patients effectively in a multidisciplinary fashion while working with psychiatry services. Our goal was to review the epidemiology, mechanisms, anatomic considerations, role of substance use, and psychiatric illness in these injuries and the approach to evaluation and treatment of these patients.

Limited data exist on how to develop resident leadership and communication skills during actual trauma resuscitations.An evaluation tool was developed to grade senior resident performance as the team leader during full-trauma-team activations. Thirty actions that demonstrated the Accreditation Council for Graduate Medical Education core competencies were graded on a Likert scale of 1 (poor) to 5 (exceptional). These actions were grouped by their respective core competencies on 5 × 7-inch index cards. In Phase 1, baseline performance scores were obtained. In Phase 2, trauma-focused communication in-services were conducted early in the academic year, and immediate, personalized feedback sessions were performed after resuscitations based on the evaluation tool. In Phase 3, residents received only evaluation-based feedback following resuscitations.In Phase 1 (October 2009 to April 2010), 27 evaluations were performed on 10 residents. In Phase 2 (April 2010 to October 2010), 28 evaluations were performed on nine residents. In Phase 3 (October 2010 to January 2012), 44 evaluations were performed on 13 residents. Total scores improved significantly between Phases 1 and 2 (p = 0.003) and remained elevated throughout Phase 3. When analyzing performance by competency, significant improvement between Phases 1 and 2 (p0.05) was seen in all competencies (patient care, knowledge, system-based practice, practice-based learning) with the exception of "communication and professionalism" (p = 0.56). Statistically similar scores were observed between Phases 2 and 3 in all competencies with the exception of "medical knowledge," which showed ongoing significant improvement (p = 0.003).Directed resident feedback sessions utilizing data from a real-time, competency-based evaluation tool have allowed us to improve our residents' abilities to lead trauma resuscitations over a 30-month period. Given pressures to maximize clinical educational opportunities among work-hour constraints, such a model may help decrease the need for costly simulation-based training.Therapeutic study, level III.

Many studies have described the detrimental effect of lack of health insurance on trauma-related outcomes. It is unclear, though, whether these effects are related to pre-injury health status, access to trauma centers, or differences in quality of care after presentation. The aim of this study was to determine if patient and insurance type affect outcomes after trauma surgery.We conducted a retrospective chart review of prospectively collected data at the American College of Surgeons level 1 trauma registry in Rhode Island. All blunt trauma patients aged 18-45 observed from 2004 to 2014 were included. Patients were divided into one of four groups on the basis of their type of insurance: Private/commercial, Medicare, Medicaid, and uninsured. Co-morbidities and infections were recorded. Analysis of variance or the Mann-Whitney U test, as appropriate, was used to analyze the data.A total of 8,018 patients were included. Uninsured patients were more likely to be male and younger, whereas the Medicare patient group had significantly fewer male patients. Rates of co-morbidities were highest in the Medicare group (28.1%) versus the private insurance (16.7%), Medicaid (19.9%), and uninsured (12.9%) groups (p 0.05). However, among patients with any co-morbidity, there was no difference in the average number of co-morbidities between insurance groups. The rate of infection was highest in Medicaid patients (7.7%) versus private (5.6%), Medicare (6.3%), and uninsured (4.3%) patients (p 0.05). Only Medicaid was associated with a significantly greater risk of developing a post-injury infection (odds ratio 1.6; 95% confidence interval 1.1-2.3).The presence of insurance, namely Medicaid, does not equate to diagnosis and management of conditions that affect trauma outcomes. Medicaid is associated with worse pre-trauma health maintenance and a greater risk of infection.

Recent studies have linked postoperative serum troponin elevation to mortality in a range of different clinical scenarios. To date, there has been no investigation into the significance of preoperative troponin elevation in emergency general surgery (EGS) patients. We define this as preoperative myocardial injury (PMI). We hypothesize that PMI seen in EGS patients may predict postoperative morbidity and mortality.Using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database, we performed a retrospective review of all EGS cases between 2008 and 2014. Patients with preoperative troponin I drawn were compared.There were 464 EGS patients who had troponin I measurements preoperatively. Eighty-two (18%) had preoperative troponin elevations. Patients with PMI were more likely to have the following preoperative physiologic derangements: acute renal failure (18% vs 4%; p = 0.002) and septic shock (40% vs 13%; p0.001). Patient comorbidities associated with PMI included congestive heart failure (13% vs 3%; p = 0.007), dialysis dependence (16% vs 3%; p = 0.002), and American Society of Anesthesiologists (ASA) class ≥ 4 (52% vs 29%; p0.001). Compared with controls, patients with PMI had higher rates of postoperative events (77% vs 52%; p0.001) and mortality (34% vs 13%; p = 0.009). Univariate analysis showed that patients with PMI had an increased risk of postoperative events (odds ratio [OR] 3.02; 95% CI 1.74 to 5.25) and mortality (OR 3.53; 95% CI 1.66 to 7.47). Multivariate analysis revealed preoperative troponin I elevation was an independent predictor of mortality (OR 3.03; 95% CI 1.19 to 7.72, p = 0.020).Emergency general surgery patients with PMI are at increased risk for postoperative events and death. Preoperative myocardial injury is an independent predictor of mortality and has prognostic utility that can prepare surgical teams for adverse events so that they can be recognized, evaluated, and treated earlier.

INTRODUCTION: Blood shortage have emerged as complicating and strategic hurdle during COVID-19 pandemic We hypothesized that adopting an ultra-restrictive transfusion protocol to preserve blood products use in surgical intensive care units (SICU) is safe and effective compared to current practices METHODS: Early in the COVID-19 pandemic (on 3/20/2020), our SICU adopted a protocol to change transfusion cutoff to hemoglobin (Hb) of 6 g/dl (or 6 5 g/dl for patients 65 years and older) instead of 7 g/dl We excluded patients who were COVID+, actively bleeding, or had signs of cardiac ischemia on admission We compared patients admitted to SICU during 2 months before (PRE) and 2 months after (POST) implementing the protocol who met the transfusion cutoff Our primary outcome was in-hospital mortality The Sequential Organ Failure Assessment (SOFA) score on the day of transfusion was calculated Secondary outcomes were new ischemic changes and total number of packed red blood cells (PRBC) transfused RESULTS: Our cohort had 261 patients (PRE n=93, POST n=168) Of those, 41 patients had Hb drop below 7 (16 in PRE, 17 2% and 27 in POST, 16 1%) In Post group, 12 patients had Hb drop below 6 and required transfusion (7 1%, p=0 02) There was no difference in gender or age between patients who met transfusion cutoff in either group There was also no difference in mortality (PRE: 5, 31 3% and POST: 3, 25%, NS) or ischemic complications (PRE: 2, 12 5% and POST: 4, 33 3%, NS) Odds ratio of mortality in POST group was 0 62 (95%CI:0 08-5 12) adjusted for age, gender, and SOFA score Mortality rate in POST patients who had Hb>6 g/dl (n=15) was 13 3% PRBC transfusion per patient was on average 4±3 8 units in PRE group and 2 4±1 5 units in POST group (NS) This represents a potential preservation of 60-100 PRBC units during the 2 months period of implementing the protocol and a potential reduction of 55-73% in blood product utilization CONCLUSIONS: Ultra-restrictive transfusion protocol appears to be safe and effective in preserving blood products utilization during a shortage crisis These results are limited by the small sample size and a large multi-center study is warranted However, these results could present a promising option during a subsequent pandemic crises or other similar disasters

Background The population of older adults is rapidly growing and more older patients are presenting with abdominal trauma. Outcomes have not been well defined for patients that require a damage control approach(DCL). Methods This was a retrospective study at a level one trauma center of patients age 65 years and older with abdominal trauma that required DCL. Outcomes reviewed included mortality, length of stay, discharge disposition. Presenting vital signs and laboratories were reviewed to identify predictors of mortality. Results 31 older patients(mean age 75.2 years) underwent DCL. Twenty-four of 31(77.4%) older patients died. Seven of 7 older DCL survivors were discharged to a rehabilitation center or nursing home. In comparisons of older DCL nonsurvivors and survivors there were not differences in presenting HR(90 versus 96; p = 0.56) or SBP in the emergency room(107 versus 116; p = 0.51). No differences in initial lactate or change in lactate concentration were found between nonsurvivors and survivors. Fifteen of 24 nonsurvivors died from multisystem organ failure. Conclusions/Implications The mortality rate of older patients that require damage control approach for is extremely high. Presenting vital signs and laboratory markers may not be useful in older patients to predict mortality.

OBJECTIVE To describe the natural history of patients with traumatic brain injury (TBI) admitted to skilled nursing facilities (SNFs) following hospitalizations. SETTING Between 2005 and 2014. PARTICIPANTS Adults who had incident admissions to skilled nursing facilities (SNFs) with a diagnosis of TBI. DESIGN Retrospective review of the Minimum Data Set. MAIN MEASURES Main variables were cognitive and physical function, length of stay, presence of feeding tube, terminal condition, and dementia. RESULTS Incident admissions to SNFs increased annually from 17 247 patients to 20 787 from 2005 to 2014. The percentage of patients with activities of daily living score 23 or more decreased from 25% to 14% (P < .05). The overall percentage of patients with severe cognitive impairment decreased from 18% to 10% (P < .05). More patients had a diagnosis of dementia in 2014 compared with previous years (P < .05), and the presence of a terminal condition increased from 1% to 1.5% over the 10-year period (P < .05). The percentage of patients who stayed fewer than 30 days was noted to increase steadily over the 10 years, starting with 48% in 2005 and ending with 53% in 2013 (P < .05). CONCLUSION Understanding past trends in TBI admissions to SNFs is necessary to guide appropriate discharge and predict future demand, as well as inform SNF policy and practice necessary to care for this subgroup of patients.

Failure to rescue (FTR) is a key metric of perioperative morbidity and mortality. We review perioperative medical comorbidities (MCMs) to determine what factors are associated with complications and rates of FTR.A retrospective review of a NSQIP database including general, vascular, and surgical subspecialty patients from a tertiary referral center between March 2008 and March 2013 was performed. Demographics, MCMs, complications, 30-day mortality, and risk of FTR associated with specific complications and MCM were evaluated.A total of 7,763 patients were included; 52.6% had MCMs and 14% (n = 1,099) experienced a complication. Patients with complications were older (64.9 vs 55 years; p0.001), more likely male (54% vs 44%; p0.001), and had more MCMs per patient (1.6 vs 1.4; p0.001). Complications were also associated with renal failure (odds ratio [OR] = 1.4; 95% CI, 1.0-2.0), steroid use (OR = 1.9; 95% CI, 1.4-2.5), CHF (OR = 2.5; 95% CI, 1.2-5.1), and ascites (OR = 9.1; 95% CI, 3.7-21.7), but not diabetes, hypertension, or COPD. There were 117 (11%) deaths among patients with complications. Adjusting for age, sex, American Society of Anesthesiologists class, and number of comorbidities, FTR was associated with postoperative respiratory failure, sepsis, and renal failure, as well as comorbid CHF, renal failure, ascites, and disseminated cancer.Specific comorbidities are associated with higher rates of complications and FTR. Preoperative CHF, renal failure, and ascites, which were associated with FTR, can reflect a physiologic inability to tolerate complication-induced fluid shifts. Postoperative mortality was associated with signs of end organ damage, including sepsis, respiratory failure, and renal failure. Earlier recognition of these complications in at-risk patients should improve rates of FTR.

Radiation associated sarcoma is a significant consequence of cancer therapy. Incidence of radiation associated sarcoma correlates with overall radiotherapy exposure. Prognosis is generally poor with 5 year survival rates lower than that for spontaneously occurring sarcomas. Surgical management presents many challenges including having to work in irradiated tissue planes while trying to achieve negative margins. We present a patient with a rare radiation associated pelvic sarcoma whose course illustrates the complexity of this problem.

Trauma remains a leading cause of death and long term-morbidity. We have shown that patients who sustain traumatic injuries are at increased risk for the development of infectious complications. Psychiatric illnesses (PIs) are also noted to occur frequently among the general population. The presence of a PI has been shown to be a risk factor for the development of infections. Despite the prevalence of both traumatic injuries and psychiatric diseases, there are little data relating the impact of PI on the outcome of patients with trauma. We hypothesize that the presence of a PI will be associated with an increased risk of an infection developing after injury.This is a five year retrospective chart review of all admitted patients with trauma age 18 years and older. Patients with and without a major psychiatric illness were compared. Demographic data, mechanism of injury and Injury Severity Score (ISS) were reviewed. Co-morbidities included diabetes mellitus, obesity, pre-injury steroid use, and International Classification of Diseases, 9th edition, based psychiatric illness. All infections were diagnosed by microbiologic criteria (urinary tract infection [UTI], ventilator-associated pneumonia) or Centers for Disease Control and Prevention criteria for clinically evident infections (surgical site infection).Of the 11,147 admitted trauma patients, 14.5% had a pre-injury PI diagnosis. The PI patients were older (61.5 ± 0.5 vs. 54.3; p 0.001), more often female (56% vs. 39.1%; p 0.001), and had no difference in blunt mechanism rates (88.4% vs. 89.9%; p = 0.06) or median ISS (9 vs. 9; p = 0.06). There was no difference between PI and non-PI patients in pre-injury diabetes mellitus (13.4% vs. 12.7%; p = 0.4), steroid use (2.5% vs. 1.9%; p = 0.1), but patients with PI were more likely to be obese (15.7% vs. 13.6%; p = 0.03). Patients with PI were more likely to have an infection develop (10.4% vs. 7.5%; p 0.001). The most common infection in both groups was UTI (6.9% vs. 4.2%; p 0.001). Compared with non-PI patients, adjusting for age, gender, ISS, diabetes mellitus, and obesity, patients with PI were more likely to have an infection develop (odds ratio 1.3, 95% confidence interval = 1.1-1.5) Conclusions: Patients with an underlying PI are at increased risk of having a UTI after traumatic injury. This study identifies a previously unknown independent risk factor for UTIs in patients with trauma. This stresses the need for increased awareness and attention to this vulnerable population.

Diabetes is one of the most prevalent comorbidities among patients with COVID-19, and specific minorities in the USA are being disproportionately affected The biologic mechanism underpinning this association is still unknown;however, there are known causal relationships between hyperglycemia and dysregulated immunity in the diabetic population in sepsis and acute respiratory distress syndrome Diabetes may impact the pathogenicity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), possibly via glycosylation of a key receptor, angiotensin-converting enzyme 2 It is imperative that we further understand this link in order to attenuate the critical illness caused by COVID-19 among diabetics

Introduction Ventilator-associated pneumonia (VAP) occurs in up to 25% of mechanically ventilated patients, with an associated mortality up to 50%. Early diagnosis and appropriate empiric antibiotic coverage of VAP are crucial. Given the multitude of noninfectious clinical and radiographic anomalies within trauma patients, microbiology from bronchioalveolar lavage (BAL) is often needed. Empiric antibiotics are administered while awaiting BAL culture data. Little is known about the effects of these empiric antibiotics on patients with negative BAL microbiology if a subsequent VAP occurs during the same hospital course. Methods This is a retrospective chart review of intubated trauma patients undergoing BAL for suspected pneumonia over a 3-y period at a Level 1 trauma center. All patients with suspected VAP undergoing a BAL receive empiric antibiotics. If microbiology data are negative at 72 h, all antibiotics are stopped; however, if the BAL returns with ≥10 5 colony-forming units per milliliter, the diagnosis of VAP is confirmed. We divided patients into three groups. Group 1 consisted of patients in whom the initial BAL was positive for VAP. Group 2 consisted of patients with an initial negative BAL, who subsequently developed VAP at a later point in the hospital course. Group 3 consisted of patients with negative BAL who did not develop a subsequent VAP. Results We obtained 499 BAL specimens in 185 patients over the 3-y period. A total of 14 patients with 23 BAL specimens initially negative for VAP subsequently developed VAP later during the same hospital stay. These patients did not have an increase in the hospital length of stay, intensive care unit days, ventilator days, or mortality compared with those who had a positive culture on the first suspicion of VAP. There was a significant increase in the percentage of Enterobacter (21% versus 8%) and Morganella (8% versus 0%) as the causative organism in these 14 patients when the VAP occurred. Furthermore, the profile of the top two organisms in each group changed. Enterobacter (21%) and Pseudomonas (17%) were the principal organisms in the initial BAL-negative group, whereas the two predominant strains in the initial positive BAL group were methicillin-sensitive Staphylococcus aureus (21%) and Haemophilus influenza (11%). Interestingly, methicillin-resistant S. aureus remained the third most common organism in both groups. Empiric antibiotics also did not seem to induce the growth of multidrug-resistant organisms, and there was no increased rate of secondary infections such as Clostridium difficile . Conclusions Ventilator-associated pneumonia remains a significant cause of morbidity and mortality in mechanically ventilated trauma patients. The diagnosis and treatment of VAP continue to be challenging. Once clinically suspected, empiric coverage decreases morbidity and mortality. Our data demonstrate that patients who receive empiric coverage exhibit a significantly different microbiologic profile compared with those who had an initial positive BAL culture. Initial empiric antibiotics in BAL-negative patients were not associated with an increase in multidrug-resistant organisms, hospital, or intensive care unit length of stay, ventilator days, and mortality or secondary infections.

A proportion of trauma patients present for evaluation in a delayed fashion after injury, likely due to a variety of medical and nonmedical reasons. There has been little investigation into the characteristics and outcomes of trauma patients who present delayed. We hypothesize that trauma patients who present in a delayed fashion are a unique population at risk of increased trauma-related complications.This was a retrospective review from 2010-2015 at a Level I trauma center. Patients were termed delayed if they presented24 hours after injury. Patients admitted within 24 hours of their injury were the comparison group. Charts were reviewed for demographics, mechanism, comorbidities, complications and outcomes. A subgroup analysis was done on patients who suffered falls.During the 5-y period, 11,705 patients were admitted. A total of 588 patients (5%) presented24 h after their injury. Patients in the delayed group were older (65 versus 55 y, P 0.001) and more likely to have psychiatric comorbidities (33% vs. 24%, P = 0.0001) than the control group. They were also more likely to suffer substance withdrawal (8.9% vs. 4.1%, P 0.001) but had toxicology testing for drugs and alcohol done at significantly lower rates. Patients that presented delayed after falls were similar in age and injury severity score (ISS) but more likely to suffer substance withdrawal when compared to those with falls that presented within 24 hours. Patients with falls that presented delayed had toxicology testing at significantly lower rates than the comparison group.Trauma patients that present to the hospital in a delayed fashion have unique characteristics and are more likely to suffer negative outcomes including substance withdrawal. Future goals will include exploring strategies for early intervention, such as automatic withdrawal monitoring and social work referral for all patients who present in a delayed fashion.

BACKGROUND Trauma produces profound inflammatory and immune responses. A second hit such as an infection further disrupts the inflammatory cascade. Inflammatory responses, following traumatic injuries, infections, or both, are emerging as biologic mediators of cardiac disease including myocardial ischemia and infarction. Inflammation-induced and stress-related cardiac damage are increasingly recognized in patients with critical illness. It is believed that cardiac dysfunction is the result of alterations in the inflammatory and immune cascades. Urinary tract infections (UTIs) and ventilator-associated pneumonia (VAP) are associated with increased mortality in trauma patients. UTIs and VAPs induced inflammatory responses. We postulate that increased mortality seen in trauma patients with infections is caused by increased rates of cardiac injury. METHODS This is a retrospective review of prospectively collected data. All trauma patients admitted to the intensive care unit at our Level I trauma center during 5 years were included in the analysis. Proportional hazard regression analysis was performed to predict suspicion of cardiac injury (troponin ordered), any cardiac injury (troponin > 0.15 ng/mL), or severe cardiac injury (troponin > 1 ng/mL) using age, sex, Injury Severity Score (ISS), pulmonary disease (chronic obstructive pulmonary disease), heart failure, hypertension, diabetes, and the presence of a UTI or VAP. A similar proportion hazard regression was performed to predict mortality. RESULTS In the model to predict any cardiac injury, chronic obstructive pulmonary disease (hazards ratio [HR], 1.9; p = 0.02), ISS (HR, 1.01; p = 0.04), VAP (HR, 5.6; p < 0.01), and UTI (HR, 2.4; p = 0.03) were significant. Neither VAP nor UTI predicted severe cardiac injury. In the model to predict death, any cardiac injury was not associated with mortality, but severe cardiac injury and UTI were associated with mortality as age increased. CONCLUSION Infectious complications have been associated with increased mortality in trauma patients. Our data demonstrate that development of VAP or UTI is associated with an increased risk of developing cardiac injury in trauma patients, which may contribute to subsequent increased mortality.

Lack of health care insurance has been correlated with increased mortality after trauma. Medical comorbidities significantly affect trauma outcomes. Access to health care and thereby being diagnosed with a pretrauma comorbidity is highly dependent on insurance status. The objective of this study was to determine whether rates of diagnosed or undiagnosed preexisting comorbidities significantly contribute to disparities in mortality rates observed between insured and uninsured trauma patients.Review of trauma patients admitted to a Level I trauma center during a 5-year period. Data extracted from the registry included age, sex, Injury Severity Score (ISS), comorbidities, mortality, and insurance status. Multivariate logistic regression analysis was performed using age, sex, and insurance status to predict comorbidities and age, sex, ISS, and insurance status to predict mortality.Insured patients were older (54 years vs. 38, p0.001) and more likely female (41.3% vs. 22.5%, p0.001). When adjusting for age and sex, insured patients were more likely to have a pretrauma diagnosis of coronary artery disease (odds ratio [OR], 2.09; 95% confidence interval [CI], 1.54-2.83), diabetes mellitus (OR, 2.09; 95% CI, 1.61-2.72), hypertension (OR, 1.97; 95% CI, 1.65-2.35), asthma/emphysema (OR, 1.64; 95% CI, 1.32-2.04), neurologic problems (OR, 1.79; 95% CI, 1.31-2.44), and gastroesophageal reflux disease (OR, 2.03; 95% CI, 1.33-3.11), compared with patients without insurance. In the analysis to predict mortality, having insurance was protective (OR, 0.57; 95% CI, 0.45-0.71). Among patients with no diagnosed comorbidities, insured patients had the lowest mortality risk (OR, 0.5; 95% CI, 0.38-0.67). When analyzing only patients with diagnosed comorbidities, insurance status had no impact on mortality risk (OR, 0.81; 95% CI, 0.53-1.22).Undiagnosed preexisting comorbidities play a crucial role in determining outcomes following trauma. Diagnosis of medical comorbidities may be a marker of access to health care and may be associated with treatment, which may explain the gap in mortality rates between insured and uninsured trauma patients.Prognostic/epidemiologic study, level III.
