RESUMO
INTRODUCTION: General surgeons (GS), orthopedic surgeons (OS), and vascular surgeons (VS) can perform below-knee amputation (BKA) operations. We compared the outcomes of BKA patients among the three specialties. METHODS: Adult patients who underwent a BKA were identified from the 2016-2018 National Surgical Quality Improvement Project database. Statistical data for orthopedic and vascular BKA cases were then compared with GS cases using logistic regression analysis. Outcomes included mortality, length of hospital stay, and complications. RESULTS: There were 9619 BKA cases. VS had the highest volume of BKA with 58.9% of the cases, compared to GS at 22.9% and OS at 18.1%. 4.4% of general surgery patients had severe frailty compared to OS (3.3%) and VS (3.4%, P < 0.001). VS has the lowest rates of emergency cases (11.9% versus 16.1 for GS versus 15.8% versus OS) and the most favorable wound classification (38.3%, versus 48.7% for GS and VS). Peripheral vascular disease was notably highest in VS (34.0% versus. 20.6% for GS and 9.9% for OS, P < 0.001). Compared to GS, VS was more likely to have a prolonged length of stay (odds ratio) (OR)(1.409), 95% CI 1.265-1.570) while OS was less likely (OR 0.650, 95% CI 0.561-0.754). OS had a lower risk of complications (OR 0.781, 95% CI 0.674-0.904). Mortality was not significantly different among the three specialties. CONCLUSIONS: The National Surgical Quality Improvement Project retrospective analysis of BKA cases suggested that mortality was not statistically different when performed by VS, GS, and OS. There were fewer overall complications when OS performed a BKA, but this is more likely a result of operating upon a generally healthier patient population with lower incidence of preoperative comorbid conditions.

PURPOSE: The effectiveness of open cardiopulmonary resuscitation (OCPR) remains controversial for trauma patients. In this current study, the role of OCPR in managing chest trauma patients is evaluated using nationwide real-world data. METHODS: From 2014 to 2015, the National Trauma Data Bank was retrospectively queried for chest trauma patients with out-of-hospital cardiac arrest status. The emergency department (ED) and overall survival of patients without signs of life were analyzed. Multivariate logistic regression (MLR) analysis was performed to evaluate independent factors of mortality for the target group. Furthermore, a subset group of patients who survived after the ED were studied, focusing on the duration of survival after leaving the ED. RESULTS: A total of 911 patients were enrolled in this study (OCPR vs. non-OCPR: 161 patients vs. 750 patients). The average overall mortality rate was 98.6% (N = 898). Among penetrating chest trauma patients, non-survivors in the ED had significantly higher proportions of gunshot injuries (83.9% vs. 69.7%, p = 0.001) and lower proportions of OCPR (20.7% vs. 44.4%, p < 0.001). MLR analysis showed that gunshot injuries and non-OCPR were significantly related to ED mortality in penetrating trauma patients without signs of life (odds ratio = 2.039, p = 0.006 and odds ratio = 2.900, p < 0.001, respectively). However, the overall survival rate of patients after ED survival (n = 99) was 9.9%, and only 21.2% (n = 21) of them survived more than 1 day after leaving the ED. CONCLUSION: OCPR could be considered in situations where appropriate indications exist. The survival benefit was observed in critically ill patients with penetrating chest trauma who show no signs of life. By enhancing ED survival, OCPR may also contribute to overall survival improvement.

PURPOSE: This study aimed to validate the previously reported association between delayed bladder repair and increased infection rates using the National Trauma Data Bank (NTDB). METHODS: Bladder injury patients with bladder repair in the NTDB from 2013 to 2015 were included. Propensity score matching (PSM) was used to compare mortality, infection rates, and hospital length of stay (LOS) between patients who underwent bladder repair within 24 h and those who underwent repair after 24 h. Linear regression and multivariate logistic regression analyses were also performed. RESULTS: A total of 1658 patients were included in the study. Patients who underwent bladder repair after 24 h had significantly higher infection rates (5.4% vs. 1.2%, p = 0.032) and longer hospital LOS (17.1 vs. 14.0 days, p = 0.032) compared to those who underwent repair within 24 h after a well-balanced 1:1 PSM (N = 166). Linear regression analysis showed a positive correlation between time to bladder repair and hospital LOS for patients who underwent repair after 24 h (B-value = 0.093, p = 0.034). Multivariate logistic regression analysis indicated that bladder repair after 24 h increased the risk of infection (odds = 3.162, p = 0.018). Subset analyses were performed on patients who underwent bladder repairs within 24 h and were used as a control group. These analyses showed that the time to bladder repair did not significantly worsen outcomes. CONCLUSIONS: Delayed bladder repair beyond 24 h increases the risk of infection and prolongs hospital stays. Timely diagnosis and surgical intervention remain crucial for minimizing complications in bladder injury patients.

PURPOSE: The impact of transarterial embolization (TAE) and nephrectomy on acute kidney injury (AKI) in blunt renal trauma patients remains unclear, and we used the National Trauma Data Bank (NTDB) to investigate this issue. METHODS: Adult patients from the NTDB between 2007 and 2015 who survived traumatic events with blunt injuries were eligible for inclusion. The exclusion criteria were those without outcome information, who required dialysis, or with chronic renal failure prior to the traumatic injury. Patients sustaining hepatic, splenic, or pelvic fractures or who had bilateral nephrectomy were also excluded. The patients were divided into three treatment groups, including conservative treatment, TAE, and nephrectomy. Two statistical models, logistic regression (LR) and inverse probability treatment weighting (IPTW), were used to clarify the AKI predictors. RESULTS: The study included 10,096 patients. There were 9697 (96.0%), 202 (2.0%) and 197 (2.0%) patients in the conservative, TAE and nephrectomy groups, respectively. Nephrectomy was a statistically significant predictor of AKI in blunt renal trauma patients in the standard LR (odds ratio [OR], 4.58; 95% confidence interval [CI] 1.92-10.38; p < 0.001) and IPTW (OR, 5.16; 95% CI 1.07-24.85; p = 0.023) models. In addition, TAE was not a risk factor for AKI in blunt renal trauma patients (p > 0.05 in all models). CONCLUSION: AKI is less likely affect patients with blunt renal trauma with TAE than those with nephrectomy. Nephrectomy is a risk factor for AKI in blunt renal trauma patients. TAE should be considered first when blunt renal trauma patients need a hemostatic procedure.

Objective: The number and type of patients treated by trauma centers can vary widely because of a number of factors. There might be trauma centers with a high volume of torso GSWs that are not designated as high-level trauma centers. We proposed that, for torso gunshot wounds (GSWs), the treating hospital's trauma volume and not its trauma center level designation drives patient prognosis.Methods: The National Trauma Data Bank was queried for torso GSWs. The characteristics of torso GSWs in trauma centers with different volumes of torso GSWs were compared. The association between torso GSW volumes of trauma centers and the outcomes of torso GSWs were evaluated with propensity score matching (PSM) and multivariate logistic regression (MLR) analysis.Results: There were 618 trauma centers that treated 14,804 torso GSW patients in two years (2014-2015). In 191 level I trauma centers, 82 of them (42.9%, 82/191) treated <1 torso GSW per month. After well-balanced PSM, patients who were treated in higher volume trauma centers (≥9 torso GSWs/month) had a significantly lower mortality rate (7.9% vs. 9.7%). Patients treated in trauma centers with ≥9 torso GSWs/month had a 30.9% (odds ratio = 0.764) lower probability of death than if sent to trauma centers with <9 torso GSWs/month. Treatment in level I or II trauma centers did not significantly affect mortality.Conclusion: There is an uneven distribution of torso GSWs among trauma centers. Torso GSWs treated in trauma centers with ≥9 torso GSWs/month have significantly superior outcomes with regard to survival.

OBJECTIVE: Stable patients with less severe injuries are not necessarily triaged to high-level trauma centers according to current guidelines. Obese patients are prone to comorbidities and complications. We hypothesized that stable obese patients with low-energy trauma have lower mortality and fewer complications if treated at Level-I/II trauma centers. Methods: Blunt abdominal trauma (BAT) patients with systolic blood pressures ≥90mmHg, Glasgow coma scale ≥14, and respiratory rates at 10-29 were derived from the National Trauma Data Bank between 2013-2015. Per current triage guidelines, these patients are not necessarily triaged to high-level trauma centers. The relationship between obesity and mortality of stable BAT patients was analyzed. A subset analysis of patients with injury severity scores (ISS) <16 was performed with propensity score matching (PSM) to evaluate outcomes between Level-I/II and Level-III/IV trauma centers. Outcomes of obese patients were compared between Level-I/II and Level-III/IV trauma centers. Non-obese patients were analyzed as a control group using a similar PSM cohort analysis. Results: 48,043 stable BAT patients in 707 trauma centers were evaluated. Non-survivors had a significantly higher body mass index (BMI) (28.7 vs. 26.9, p < 0.001) and higher proportion of obesity (35.6% vs. 26.5%, p < 0.001) than survivors. After a PSM (1,502 obese patients: 751 in Level-I/II trauma centers and 751 in Level-III/IV trauma centers), obese patients treated in Level-I/II trauma centers had significantly lower complication rates than obese patients treated in other trauma centers (20.2% vs. 26.6%, standardized difference = 0.151). The complication rate of obese patients treated at Level-I/II trauma centers was 20.6% lower than obese patients treated at other trauma centers. Conclusion: Obesity plays a role in the mortality of stable BAT patients. Obese patients with ISS < 16 have lower complication rates at Level-I/II trauma centers compared to obese patients treated at other trauma centers. Obesity may be a consideration for triaging to Level-I/II trauma centers.

INTRODUCTION: Obesity is associated with increased morbidity and mortality in abdominal trauma patients. The characteristics of abdominal trauma patients with poor outcomes related to obesity require evaluation. We hypothesize that obesity is related to increased mortality and length of stay (LOS) among abdominal trauma patients undergoing laparotomies. METHODS: Abdominal trauma patients were identified from the National Trauma Data Bank between 2013 and 2015. Patients who received laparotomies were analyzed using propensity score matching (PSM) to evaluate the mortality rate and LOS between obese and non-obese patients. Patients without laparotomies were analyzed as a control group using PSM cohort analysis. RESULTS: A total of 33,798 abdominal trauma patients were evaluated, 10,987 of them received laparotomies. Of these patients, the proportion of obesity in deceased patients was significantly higher when compared to the survivors (33.1% vs. 26.2%, p < 0.001). Elevation of one kg/m2 of body mass index independently resulted in 2.5% increased odds of mortality. After a well-balanced PSM, obese patients undergoing laparotomies had significantly higher mortality rates [3.7% vs. 2.4%, standardized difference (SD) = 0.241], longer hospital LOS (11.1 vs. 9.6 days, SD = 0.135), and longer intensive care unit LOS (3.5 vs. 2.3 days, SD = 0.171) than non-obese patients undergoing laparotomies. CONCLUSIONS: Obesity is associated with increased mortality in abdominal trauma patients who received laparotomies versus those who did not. Obesity requires a careful evaluation of alternatives to laparotomy in injured patients.

BACKGROUND: Morbid obesity is usually accompanied by both subcutaneous and visceral fat accumulation. Fat can mimic an air bag, absorbing the force of a collision. We hypothesized that morbid obesity is mechanically protective for hollow viscus organs in blunt abdominal trauma (BAT). METHODS: The National Trauma Data Bank (NTDB) was queried for BAT patients from 2013 to 2015. We looked at the rate of gastrointestinal (GI) tract injuries in all BAT patients with different BMIs. A subset analysis of BAT patients with operative GI tract injuries was performed to evaluate the need for abdominal operation. Multivariate analyses were carried out to identify factors independently associated with increased GI tract injuries and associated abdominal operations. RESULTS: A total of 100,459 BAT patients were evaluated in the NTDB. Patients with GI tract injury had a lower proportion of morbidly obese patients [body weight index (BMI) ≥ 40 kg/m2)] (3.7% vs. 4.2%, p = 0.015) and instead had more underweight patients (BMI < 18.5) (5.9% vs. 5.0%, p < 0.001). The risk of GI tract injury decreased 11.6% independently in morbidly obese patients and increased 15.7% in underweight patients. Of the patients with GI tract injuries (N = 11,467), patients who needed a GI operation had a significantly lower proportion of morbidly obese patients (3.2% vs. 5.3%, p < 0.001). The risk of abdominal operation for GI tract injury decreased 57.3% independently in morbidly obese patients. Compared with underweight patients, morbidly obese patients had significantly less GI tract injury (6.0% vs. 13.3%, p < 0.001) and associated abdominal operation rates (65.2% vs. 73.3%, p < 0.001). CONCLUSION: Obesity is protective in BAT. This translates into lower rates of GI tract injury and operation in morbidly obese patients. In contrast, underweight patients appear to suffer a higher rate of GI tract injury and associated GI operations.

Etherified Carboxymethylcellulose Matrix (eCMC) is a revolutionary application of carboxymethylcellulose (CMC) in wound care, known for its potential in hemostasis and tissue regeneration. This study aims to investigate the mechanism of eCMC in tissue healing by establishing a rat burn model and administering eCMC as a treatment. The objective is to analyze cytokines and inflammatory mediators using a Cytokine Array and histochemical staining to understand the effects of eCMC on tissue regeneration. A rat burn model was created, and eCMC was applied as a treatment. Tissue samples were collected at multiple time points to assess the expression of cytokines and inflammatory mediators using a Cytokine Array. Additionally, histochemical staining was performed to evaluate tissue regeneration factors. eCMC induced the expression of endogenous cytokines, particularly VEGF and PDGF, while inhibiting inflammatory cytokines such as CINC-1, CINC-2, and MMP-8. This dual action facilitated wound healing and mitigated the risk of infection. eCMC demonstrates promising potential for enhancing skin regeneration. Further research is warranted to delve into the precise mechanism of eCMC's cytokine regulation. In vitro and in vivo studies should be conducted to comprehensively investigate the therapeutic capabilities of eCMC in wound healing.
RESUMO
BACKGROUND: The appropriate timing of surgical intervention for bladder injuries is not well-defined. The effect of time to surgery on the outcomes of patients with a bladder injury was assessed using data from the Trauma Quality Improvement Program. METHODS: Patients with dominant or isolated bladder injuries who underwent surgical repair from 2017 to 2019 were studied. Mortality, infection (surgical site infection or sepsis), acute kidney injury, overall length of stay, and length of stay after surgery were compared between patients who underwent bladder repair within and after 24 hours of arrival at the emergency department. The role of time to surgical repair in the outcomes of patients with a bladder injury was evaluated. RESULTS: A total of 1,507 patients with a mean time to bladder repair of 14.0 hours were studied. In total, 233 (15.5%) patients with a bladder injury underwent bladder repair more than 1 day after emergency department arrival. These patients had significantly more infections (5.6% vs 2.5%, P = .011), more acute kidney injuries (7.8% vs 1.8%, P < .001), and a longer length of stay after surgery (16.0 vs 12.3 days, P = .001) than patients who underwent bladder repair within 1 day. A time to bladder repair longer than 24 hours after emergency department arrival did not significantly affect mortality (P = .075) but significantly increased the risk of infection/acute kidney injury (odds = 1.823, P = .040). However, the infection/acute kidney injury risk did not increase with increasing time to surgery in patients who underwent bladder repair within 24 hours (P = .120). CONCLUSION: Patients with dominant or isolated bladder injuries may have a poor outcome (ie, increased infection rate, acute kidney injury, longer overall length of stay, and longer length of stay after bladder repair) if they undergo surgical repair more than 24 hours after arrival at the emergency department.

OBJECTIVES: The role of thoracic endovascular aortic replacement (TEVAR) in patients with concomitant blunt thoracic aortic injury (BTAI) and blunt abdomen trauma (BAT) was evaluated using nationwide real-world data. The risk of post-TEVAR abdominal haemorrhage was studied. METHODS: Patients with BTAI and BAT in the National Trauma Data Bank were retrospectively studied. Propensity score matching was used to evaluate the effect of TEVAR in delayed abdominal surgeries for haemostasis and the delayed need for blood transfusion. A multivariable logistic regression analysis was used to evaluate the independent risk factors for delayed intra-abdominal haemorrhage in these patients. RESULTS: A total of 928 concomitant BTAI and BAT patients were studied (TEVAR versus non-TEVAR, 206 vs 722). After a well-balanced propensity score matching analysis, patients who received TEVAR had significantly more delayed abdominal surgeries for haemostasis (7.7% vs 4.5%, standardized mean difference = 0.316) and delayed need for blood transfusion (11.6% vs 7.1%, standardized mean difference = 0.299) than those who did not. The multivariable logistic regression analysis showed that TEVAR increased the need for delayed abdominal surgeries (odds ratio = 2.026, P = 0.034). Among the patients who underwent TEVAR, the patients with delayed abdominal surgeries for haemostasis had a significantly higher proportion of severe abdominal injury (abdominal Abbreviated Injury Scale score of 4 or 5) than patients without delayed abdominal surgeries for haemostasis (31.6% vs 15.5%, P = 0.038). CONCLUSIONS: Patients with concomitant BTAI and BAT had a higher risk of intra-abdominal haemorrhage after TEVAR, especially patients with severe abdominal trauma.

BACKGROUND: Open pelvic fractures are rare but complex injuries. Concomitant external and internal hemorrhage and wound infection-related sepsis result in a high mortality rate and treatment challenges. Here, we validated the World Society Emergency Society (WSES) classification system for pelvic injuries in open pelvic fractures, which are quite different from closed fractures, using the National Trauma Data Bank (NTDB). METHODS: Open pelvic fracture patients in the NTDB 2015 dataset were retrospectively queried. The mortality rates associated with WSES minor, moderate and severe injuries were compared. A multivariate logistic regression model (MLR) was used to evaluate independent factors of mortality. Patients with and without sepsis were compared. The performance of the WSES classification in the prediction of mortality was evaluated by determining the discrimination and calibration. RESULTS: A total of 830 open pelvic fracture patients were studied. The mortality rates of the mild, moderate and severe WSES classes were 3.5%, 11.2% and 23.8%, respectively (p < 0.001). The MLR analysis showed that the presence of sepsis was an independent factor of mortality (odds of mortality 9.740, p < 0.001). Compared with patients without sepsis, those with sepsis had significantly higher mortality rates in all WSES classes (minor: 40.0% vs. 3.1%, p < 0.001; moderate: 50.0% vs. 9.1%, p < 0.001; severe: 66.7% vs. 22.2%, p < 0.001). The receiver operating characteristic (ROC) curve showed an acceptable discrimination of the WSES classification alone for evaluating the mortality of open pelvic fracture patients [area under curve (AUC) = 0.717]. Improved discrimination with an increased AUC was observed using the WSES classification plus sepsis (AUC = 0.767). CONCLUSIONS: The WSES guidelines can be applied to evaluate patients with open pelvic fracture with accurate evaluation of outcomes. The presence of sepsis is recommended as a supplement to the WSES classification for open pelvic fractures.

PURPOSE: Geriatric trauma patients present physiological challenges to care providers. A nationwide analysis was performed to evaluate the roles of age alone versus age-associated comorbidities in the morbidity and mortality of elderly patients with blunt abdominal trauma (BAT). METHODS: Patients with BAT registered in the National Trauma Data Bank from 2013 to 2015 were analyzed using propensity score matching (PSM) to evaluate the mortality rate, complication rate, hospital length of stay (LOS), intensive care unit (ICU) LOS and ventilator days between young (age < 65) and elderly (age ≥ 65) patients. An adjusted multivariate logistic regression (MLR) model was also used to evaluate the effect of age itself and age-associated comorbidities on mortality. RESULTS: There were 41,880 patients with BAT during the study period. In elderly patients, the injury severity score (ISS) decreased with age, but the mortality rate increased inversely (from 5.0 to 13.5%). Under a similar condition and proportion of age-associated comorbidities after a well-batched PSM analysis, elderly patients had significantly higher mortality rates (8.0% vs. 1.9%, p < 0.001), higher complication rates (35.1% vs. 30.6%, p < 0.001), longer hospital LOS (8.9 vs. 8.1 days, p < 0.001), longer ICU LOS (3.7 vs. 2.7 days, p < 0.001) and more ventilator days (1.1 vs. 0.5 days, p < 0.001) than young patients. Furthermore, the MLR analysis showed that age itself served as an independent factor for mortality (odds ratio: 1.049, 95% CI 1.043-1.055, p < 0.001), but age-associated comorbidity was not. CONCLUSION: In patients with BAT, age itself appeared to have an independent and deleterious effect on mortality, but age-associated comorbidity did not.

BACKGROUND: In the management of patients with blunt abdominal trauma, delayed diagnosis and treatment of hollow viscus injury can occur. We assessed the effect of the time to surgery on the outcomes of blunt hollow viscus injury patients. METHODS: The National Trauma Data Bank was queried from 2012 to 2015 to identify patients with blunt hollow viscus injury for inclusion. Patients with unstable hemodynamics, concomitant intra-abdominal organ injuries, or other severe extra-abdominal injuries were excluded. Inverse probability of treatment weighting and multivariate logistic regression were used to evaluate the effect of the time to surgery on the outcomes. RESULTS: In total, 2,997 patients with blunt hollow viscus injury were studied; the mean time to abdominal surgery was 6.7 hours. Twenty-two hours was selected as a cutoff value for further analyses because of an observed transition zone at that time in the distribution of mortality and severe sepsis rates. After adjustment, patients who underwent surgery within 22 hours had a significantly lower mortality rate (1.2% vs 4.2%), lower sepsis rate (0.9% vs 4.5%), shorter hospital length of stay (8.7 vs 12.0 days), and shorter intensive care unit length of stay (1.4 vs 3.3 days). In patients who underwent surgery within 22 hours, neither mortality nor sepsis were affected significantly by the time to surgery. CONCLUSION: In the management of patients with blunt hollow viscus injury, early surgical treatment is needed. Patients with isolated blunt hollow viscus injury may have a poor outcome if they undergo abdominal surgery more than 22 hours after arrival in the emergency department.

BACKGROUND: There are several burn scores used to predict mortality in burn patients. However, minimal data exists on the role of laboratory values in risk stratification. We hypothesized that laboratory derangements seen on admission can predict mortality in burn patients. MATERIALS AND METHODS: A retrospective chart review was conducted on burn patients admitted to a busy Level 1 Trauma and Burn Center from 2013 to 2019. Data analysis included patients with partial or full thickness burns and a total body surface area (TBSA) burn greater than 15%. Exclusion criteria included patients presenting with electrical burns, non-thermal conditions (Stevens-Johnson Syndrome, Toxic Epidermal Necrolysis, or soft tissue infections) or patients with significant polytrauma. RESULTS: 112 patients were included in the analysis. Admission phosphate, creatinine, albumin, and glucose levels were associated with mortality. There was a difference in serum phosphate (3.48 and 6.04 mg/dL), creatinine (0.85 and 1.13 mg/dL), albumin (3.26 and 2.3 mg/dL), and glucose (138 and 233 mmol/L) levels for survivors and non-survivors; respectively. There were increased mortality rates seen in patients presenting with abnormal serum levels compared to normal serum levels (Phosphate: 7.5% vs. 53.3%, creatinine: 13.5% vs. 38.9%, albumin: 38.5% vs. 8.10% and glucose: 10.1% vs. 31.6% (normal vs. abnormal; respectively)). Serum sodium, potassium, and hemoglobin levels had no association with mortality. DISCUSSION: Specific laboratory derangements seen on admission are associated with an increased risk for mortality. This can be used as a framework for future studies in risk stratification of burn victims.
RESUMO
INTRODUCTION: As recently as 2006, carburetor flash burns comprised as much as 27% of admissions for car-related burns, despite the fact carburetors were last installed in pre-1990 automobiles. The prevalence of this injury pattern is related to the estimated 14 million cars on the road today that were manufactured prior to that year. The aim of this study was to investigate modern sources of automotive burns and describe any new trends in automotive burn-related epidemiology. MATERIALS AND METHODS: A retrospective review was conducted of all burn admissions from the years 2009-2013 to identify patients who suffered automotive-related burns. Pediatric patients (<18 years old) were excluded. Demographic information including age, gender, mechanism of injury, occupation, TBSA, number of operations, and length of hospital stay were recorded. RESULTS: From 2009-2013, the burn center saw 83 admissions for automotive-related burns. 14.5% of patients were mechanics. The most common injury pattern was from radiator burns (47%), followed by gasoline related burns (30%). There were only two carburetor burns (2.4%). 67.4% of patients were treated for less than two hospital days and there was one death (1.2% mortality). CONCLUSION: Despite the removal of carburetors from engines and a decrease in this specific mechanism, a significant morbidity remains with gasoline-inflicted burns. More public awareness is needed for the safe removal of radiator caps and handling of chemicals in overheating engines.

BACKGROUND: In 2017, a novel classification for pelvic injuries was established by the World Society of Emergency Surgery (WSES). We validated its effectiveness using nationwide real-world data. The roles of associated vascular injury and open fracture in this system were also evaluated. METHODS: Patients with pelvic fractures in the National Trauma Data Bank 2015 dataset were retrospectively studied. First, the mortality rates were compared by WSES classification. Second, independent predictors of mortality were evaluated using a multivariate logistic regression model. Patients with and without associated vascular injuries and the same hemodynamic and pelvic ring stability statuses were compared. Patients with associated vascular injuries were compared to the proportion of nonsurvivors and survivors with unstable pelvic ring injuries. Third, the outcomes were compared between patients with open pelvic fracture and closed pelvic fracture in the mild, moderate and severe WSES classes. RESULTS: During the 12-month study period, 44,163 blunt pelvic fracture patients were included. The mortality rates were 1.8%, 3.8% and 10.6% for the mild, moderate and severe WSES classes, respectively (p < 0.001). MLR analysis showed that unstable pelvic ring injury did not significantly affect mortality (p = 0.549), whereas open pelvic fracture and associated vascular injury were independent predictors of mortality (odds of mortality: open pelvic fracture 1.630, p < 0.001; associated vascular injury 1.602, p < 0.001). Patients with associated vascular injuries showed that there was no significant difference in the proportion of patients with unstable pelvic ring injuries between survivors and nonsurvivors (37.2% vs. 32.7%, p = 0.323). In all three classes, patients with open pelvic fractures had significantly higher mortality rates and infection rates than patients with closed fractures (mortality rates: minor 3.5% vs. 1.8%, p = 0.009, moderate 11.2% vs. 3.3%, p < 0.001, severe 23.8% vs. 9.8%, p < 0.001; infection rates: minor 3.3% vs. 0.7%, p < 0.001, moderate 6.7% vs. 2.1%, p < 0.001, severe 7.9% vs. 2.8%, p < 0.001). CONCLUSIONS: Based on this nationwide study, the WSES guideline provides an accurate and reproducible classification of pelvic fractures. It is recommended that open/closed fractures and associated vascular injuries be evaluated as supplements of the WSES classification.

INTRODUCTION: Hidradenitis suppurativa (HS) is a chronic, debilitating disease associated with inflammation, recurrent abscesses, and fistulae of skin containing apocrine sweat glands. We hypothesize that the need for skin grafting after vacuum-assisted closure was decreased with increasing body mass index (BMI). METHODS: Seventy-one consecutive patients with excisions for HS were retrospectively evaluated for demographic data, number of excisions, the total area of excised skin, need for skin grafting, and BMI. Patients were stratified for BMI and underwent logistic regression to compare all other variables. RESULTS: Average for BMI was 30.8 ± 7.72, age was 36.89 ±13.52, area excised was 743 cm2 ± 774 cm2, mean operating room trips were 2.62 ± 1.59, and skin grafting was 0.52 ± 0.55. Patients were 60% male. Forty out of 71 patients were obese. There was no correlation between age, BMI, sex, thenumber of excisions, amount of skin excised, or need for a skin graft. There was a statistically significant relationship between the amount of skin excised and the need for skin grafting (P = .006). CONCLUSIONS: The amount of skin affected by HS appears to be independent of patient BMI. The need for skin grafting is solely dependent upon the amount of tissue excised. APPLICABILITY OF RESEARCH TO PRACTICE: This knowledge will help preoperative planning for all patients with HS, regardless of BMI.

OBJECTIVE: The revised Baux score (age total body surface area (TBSA) burned and inhalation injury)) is predictive of mortality in burn patients. Our study objective was to assess whether the addition of body mass index (BMI) to the revised Baux score would be of value. We posited that increasing BMI follows a pattern similar to age and TBSA in the revised Baux score after severe burn injury. METHODS: Patient data from the burn registry was queried for patients admitted between 1/1/2013 to 8/31/2019. Patients 12 years or older with a TBSA of 20% or greater burn were included. Inpatient outcomes were analyzed based on BMI. RESULTS: 56 of 1365 patients met inclusion criteria. Mean age of the study population was 48.25 years and 64.3% of patients were male. Median BMI was 25.8 and median TBSA was 26.5. Inhalation injury was present in 44.6% (25/56) of patients. Median hospital length of stay (LOS) and ICU LOS were 21.5 and 17 days respectively. On bivariate analysis, non-survivors had higher TBSA (41.5% vs 25.5%, p = 0.034), more inhalation injury (83.3%, 10/12 vs 34.8%, 15/43 p = 0.003) and higher complication rates (91.6%, 11/12 vs 59.1 %, 25/43, p = 0.043). Survivors also had higher BMI (28.2 vs 23, p = 0.003) and increased hospital LOS (24 vs 5.5, p = 0.003). Automatic model fit in binary logistic regression showed a negative relationship between BMI and mortality. CONCLUSION: We found a negative relationship between BMI and mortality. Pre-obesity appears to have a protective role, but BMI was not found to be a useful addition to the revised Baux score. Larger sample sizes may be of benefit a for a for a more definitive understanding of the role of BMI with regards to burn survival.
