RESUMO
PURPOSE: Following motor vehicle collisions (MVCs), patients often undergo extensive computed tomography (CT) imaging. However, pregnant trauma patients (PTPs) represent a unique population where the risk of fetal radiation may supersede the benefits of liberal CT imaging. This study sought to evaluate imaging practices for PTPs, hypothesizing variability in CT imaging among trauma centers. If demonstrated, this might suggest the need to develop specific guidelines to standardize practice. METHODS: A multicenter retrospective study (2016-2021) was performed at 12 Level-I/II trauma centers. Adult (≥18 years old) PTPs involved in MVCs were included, with no patients excluded. The primary outcome was the frequency of CT. Chi-square tests were used to compare categorical variables, and ANOVA was used to compare the means of normally distributed continuous variables. RESULTS: A total of 729 PTPs sustained MVCs (73% at high speed of ≥ 25 miles per hour). Most patients were mildly injured but a small variation of injury severity score (range 1.1-4.6, p < 0.001) among centers was observed. There was a variation of imaging rates for CT head (range 11.8-62.5%, p < 0.001), cervical spine (11.8-75%, p < 0.001), chest (4.4-50.2%, p < 0.001), and abdomen/pelvis (0-57.3%, p < 0.001). In high-speed MVCs, there was variation for CT head (12.5-64.3%, p < 0.001), cervical spine (16.7-75%, p < 0.001), chest (5.9-83.3%, p < 0.001), and abdomen/pelvis (0-60%, p < 0.001). There was no difference in mortality (0-2.9%, p =0.19). CONCLUSION: Significant variability of CT imaging in PTPs after MVCs was demonstrated across 12 trauma centers, supporting the need for standardization of CT imaging for PTPs to reduce unnecessary radiation exposure while ensuring optimal injury identification is achieved.

INTRODUCTION: Guidelines encourage higher doses of low molecular weight heparin (LMWH) for prophylaxis in trauma patients. The risks of LMWH must be considered for patients who require an epidural catheter. We compared adequate and inadequate prophylaxis to determine if venous thromboembolism (VTE) and complication rates differed among patients with epidural catheters. METHODS: Trauma patients who required an epidural catheter between 2012 and 2019 were reviewed for VTE and epidural-related complications. Adequate dosing was defined as enoxaparin 30 mg or 40 mg twice daily. Inadequate dosing was defined as unfractionated heparin subcutaneously or enoxaparin once daily. RESULTS: Over the 8-y study period, 113 trauma patients required an epidural catheter of which 64.6% were males with a mean age of 55.8 y and injury severity score of 14. Epidural catheters were associated with 11 (9.7%) patients developing an acute deep vein thrombosis (DVT) and 2 (1.8%) patients with an acute pulmonary embolism. Those patients who received adequate doses of enoxaparin were less likely to have any VTE or DVT. Complications associated with epidural catheters were not dependent on the type of pharmacological prophylaxis. CONCLUSIONS: Given the high VTE rate observed in trauma patients who required an epidural catheter, along with the low complication rate that was observed independent of the type of pharmacological prophylaxis given, the data indicate that current efforts for higher doses of LMWH appear to be safe and associated with a lower VTE rate.

BACKGROUND: Central and systemic immune dysfunction after traumatic brain injury (TBI) can lead to infectious-related complications, which may result in delayed mortality. The role of early empiric antibiotics after TBI has not been characterized to date, but is recommended in select cases to decrease complications. We aimed to determine the relationship between early antibiotic use and in-hospital mortality in TBI patients. METHODS: A retrospective review was conducted of TBI patients requiring ICU admission at an urban, academic, Level I trauma center from 01/2014 to 08/2016. Data collection included demographics, injury characteristics, details regarding antibiotic use, and outcomes. Early antibiotic administration was defined as any antibiotic given within 48 hs from admission. Patients given early antibiotics (EARLY) were compared to those who received their first dose later or did not receive any antibiotics (non-EARLY). RESULTS: Of the 488 TBI patients meeting inclusion criteria, 189 (38.7%) received early antibiotics. EARLY patients were younger (EARLY 54.2 versus non-EARLY 61.5 ys, P <0.01) and more likely to be male (71.4% versus 60.9%, P = 0.02). Injury severity scores (23.6 versus 17.2, P <0.01) and regional head abbreviated injury scale scores (3.9 versus 3.7, P <0.01) were significantly higher in patients who received early antibiotics. Unadjusted in-hospital mortality rates were similar, however EARLY was associated with a lower mortality rate (AOR 0.17, 95% CI: 0.07 - 0.43, adjusted P <0.01) after adjusting for confounders. CONCLUSIONS: Despite presenting with a higher injury burden, TBI patients who received early antibiotics had a lower associated mortality rate compared to their counterparts. Future investigations are necessary to understand the underlying mechanisms that result in this potential survival benefit.

BACKGROUND: Patients with traumatic brain injury (TBI) are at high risk of venous thromboembolism (VTE). Recent guidelines recommend starting TBI patients on enoxaparin 30 mg twice daily and then considering weight-based dosing. Creatinine clearance may be better than weight for patients when considering high and low enoxaparin dose requirements. We hypothesize that creatinine clearance (CrCl) predicts goal enoxaparin dose better than weight-based dosing. METHODS: A retrospective review was conducted on patients admitted to an urban, academic Level I trauma center from August 2017 to February 2020. Patients were included if greater than 18 years, admitted longer than 48 hours, and head and neck AIS ≥ 3. Patients were excluded if they did not have TBI, if they received deep vein thrombosis prophylaxis other than enoxaparin 12-hour dosing, if no anti-Xa levels were drawn, or if the goal anti-Xa level was not reached. Patients were grouped into dosing cohorts based on dose of enoxaparin required to reach goal. Pearson's correlation was used to compare mean CrCl and mean weight across dosing cohorts. RESULTS: A total of 120 patients met inclusion and exclusion criteria, mean age was 47 years and 68% of patients were male. The mean hospital length of stay was 24 days. There were 5 (4.2%) deep vein thrombosis, no pulmonary embolism, and 5 (4.2%) patients died. Mean CrCl increased significantly with increased dosing of enoxaparin, Pearson's correlation coefficient of 0.484 ( p < 0.001). Weight on admission also increased with increasing enoxaparin dose requirements, with Pearson's correlation coefficient of 0.411 ( p < 0.001). CONCLUSION: Creatine clearance predicts goal enoxaparin dose in TBI better than a weight-based dosing strategy. Further research with a larger patient population is required to validate CrCl values to guide enoxaparin dosing. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

BACKGROUND: Current guidelines recommend 24-hour telemetry monitoring for isolated sternal fractures (ISFs) with electrocardiogram (ECG) abnormalities or troponin elevation. However, a single-center study suggested ISF patients with minor ECG abnormalities (sinus tachycardia/bradycardia, nonspecific arrhythmia/ST-changes, and bundle branch block) may not require 24-hour telemetry monitoring. This study sought to corroborate this, hypothesizing ISF patients would not develop blunt cardiac injury (BCI). MATERIALS & METHODS: A retrospective study was performed at 8 trauma centers (1/2018-8/2020). Patients with ISF (abbreviated injury scale <2 for the head/neck/face/abdomen/extremities) and minor ECG abnormalities or troponin elevations were included. Patients with multiple rib fractures or hemothorax/pneumothorax were excluded. The primary outcome was an echocardiogram confirmed BCI. The secondary outcome was significant BCI defined as cardiogenic shock, dysrhythmia requiring treatment, post-traumatic cardiac structural defects, unexplained hypotension, or cardiac-related procedures. Descriptive statistics were performed. RESULTS: Of 124 ISF patients with minor ECG abnormalities or troponin elevation, 90% were admitted with a mean stay of 35 hours. Echocardiogram was performed for 31.5% of patients, 10 (25.6%) of which had abnormalities. However, no patient had BCI diagnosed on echocardiography. In total, 2 patients (1.6%) had a significant BCI (atrial fibrillation and supraventricular tachycardia at 10 and 82 hours after injury). No patient died. CONCLUSIONS: Following ISF with minor ECG changes or troponin elevation, <2% suffered significant BCI, and none had an echocardiogram diagnosed BCI, despite >30% receiving echocardiogram. These findings challenge the dogma of mandatory observation periods following ISF with associated ECG abnormalities and support the lack of utility for routine echocardiography in these patients.
RESUMO
BACKGROUND: Pregnant trauma patients (PTPs) undergo observation and fetal monitoring following trauma due to possible fetal delivery (FD) or adverse outcome. There is a paucity of data on PTP outcomes, especially related to risk factors for FD. We aimed to identify predictors of posttraumatic FD in potentially viable pregnancies. METHODS: All PTPs (≥18 years) with ≥24-weeks gestational age were included in this multicenter retrospective study at 12 Level-I and II trauma centers between 2016 and 2021. Pregnant trauma patients who underwent FD ((+) FD) were compared to those who did not deliver ((-) FD) during the index hospitalization. Univariate analyses and multivariable logistic regression were performed to identify predictors of FD. RESULTS: Of 591 PTPs, 63 (10.7%) underwent FD, with 4 (6.3%) maternal deaths. The (+) FD group was similar in maternal age (27 vs. 28 years, p = 0.310) but had older gestational age (37 vs. 30 weeks, p < 0.001) and higher mean injury severity score (7.0 vs. 1.5, p < 0.001) compared with the (-) FD group. The (+) FD group had higher rates of vaginal bleeding (6.3% vs. 1.1%, p = 0.002), uterine contractions (46% vs. 23.5%, p < 0.001), and abnormal fetal heart tracing (54.7% vs. 14.6%, p < 0.001). On multivariate analysis, independent predictors for (+) FD included abdominal injury (odds ratio [OR], 4.07; confidence interval [CI], 1.11-15.02; p = 0.035), gestational age (OR, 1.68 per week ≥24 weeks; CI, 1.44-1.95; p < 0.001), abnormal FHT (OR, 12.72; CI, 5.19-31.17; p < 0.001), and premature rupture of membranes (OR, 35.97; CI, 7.28-177.74; p < 0.001). CONCLUSION: The FD rate was approximately 10% for PTPs with viable fetal gestational age. Independent risk factors for (+) FD included maternal and fetal factors, many of which are available on initial trauma bay evaluation. These risk factors may help predict FD in the trauma setting and shape future guidelines regarding the recommended observation of PTPs. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Nearly 10% of pregnant women suffer traumatic injury. Clinical outcomes for pregnant trauma patients (PTPs) with severe injuries have not been well studied. We sought to describe outcomes for PTPs presenting with severe injuries, hypothesizing that PTPs with severe injuries will have higher rates of complications and mortality compared to less injured PTPs. A post-hoc analysis of a multi-institutional retrospective study at 12 Level-I/II trauma centers was performed. Patients were stratified into severely injured (injury severity score [ISS] > 15) and not severely injured (ISS < 15) and compared with bivariate analyses. From 950 patients, 32 (3.4%) had severe injuries. Compared to non-severely injured PTPs, severely injured PTPs were of similar maternal age but had younger gestational age (21 vs 26 weeks, p = 0.009). Penetrating trauma was more common in the severely injured cohort (15.6% vs 1.4%, p < 0.001). The severely injured cohort more often underwent an operation (68.8% vs 3.8%, p < 0.001), including a hysterectomy (6.3% vs 0.3%, p < 0.001). The severely injured group had higher rates of complications (34.4% vs 0.9%, p < 0.001), mortality (15.6% vs 0.1%, p < 0.001), a higher rate of fetal delivery (37.5% vs. 6.0%, p < 0.001) and resuscitative hysterotomy (9.4% vs. 0%, p < 0.001). Only approximately 3% of PTPs were severely injured. However, severely injured PTPs had a nearly 40% rate of fetal delivery as well as increased complications and mortality. This included a resuscitative hysterotomy rate of nearly 10%. Significant vigilance must remain when caring for this population.
RESUMO
BACKGROUND: Guidelines for enoxaparin dosing after trauma recommend an initial dose of 40 mg twice daily for most patients and then adjusting by anti-Xa levels. Previous studies indicated higher enoxaparin doses are necessary with higher levels of creatinine clearance (CrCl). We sought to determine if the goal enoxaparin dose correlates with the admission CrCl to reduce the reliance on measuring anti-Xa levels. STUDY DESIGN: A retrospective review was conducted of patients admitted to an urban, academic Level 1 trauma center from April 2017 to February 2020. Patients started on enoxaparin who reached goal anti-Xa trough levels were included, and patients were excluded if they did not reach goal anti-Xa levels. Data collection included patient demographics, injury characteristics, admission CrCl, and final enoxaparin dose. CrCl was then correlated with the final enoxaparin dose. RESULTS: Of 421 patients included, the mean age was 46.6 years and 73% were male. The median goal enoxaparin dose was 40 mg twice daily. The mean CrCl significantly increased with increasing twice-daily doses of enoxaparin (20 mg: 69.2 mL/min; 30 mg: 89 mL/min; 40 mg: 112.8 mL/min; 50 mg: 140.5mL/min; 60 mg: 147.4 mL/min; and 70 mg: 140 mL/min; p < 0.01). CONCLUSIONS: Admission CrCl may predict the enoxaparin dose required to achieve adequate anti-Xa levels. Our data indicate that CrCls of approximately 70, 90, 110, 140, and 150 mL/min may predict the twice-daily enoxaparin doses of 20, 30, 40, 50, and 60 mg, respectively. CrCl dosing guidance may reduce the time to goal anti-Xa levels and the frequency of anti-Xa measurements. Further research is necessary, and enoxaparin dosing should continue to be monitored by anti-Xa levels.

BACKGROUND: The desire to deliver appropriate care after trauma creates challenges when deciding to proceed if care appears futile. This study aimed to analyze survival rates for trauma patients who undergo closed chest compressions by decade of life. METHODS: A multicenter retrospective review of trauma patients with an Injury Severity Score ≥16 who underwent closed chest compressions from 2015 to 2020 at four large, urban, academic Level I trauma centers was conducted. Those with intraoperative arrest were excluded. The primary endpoint was survival to discharge. RESULTS: Of the 247 patients meeting inclusion criteria, 18% were 70 years or older, 78% were male, and 24% presented due to a penetrating mechanism of injury. Compressions occurred in the prehospital setting (56%), emergency department (21%), intensive care unit (19%), and on the floor (3%). On average, patients arrested on hospital day 2, and survived 1 day after arrest if return of spontaneous circulation was achieved. Overall mortality was 92%. Average hospital length of stay was lower in patients 70 years or older (3 days vs. 6 days, p < 0.01). Survival was highest in patients 60 years to 69 years (24%), and although patients 70 years or older presented with lower Injury Severity Scores (28 vs. 32, p = 0.04), no patient 70 years or older survived to hospital discharge (0% v 9%, p = 0.03). CONCLUSION: Closed chest compressions are associated with a high mortality rate after moderate to severe trauma with 100% mortality in patients older than 70 years. This information may assist with the decision to withhold chest compression, especially in older adults. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

BACKGROUND: Effects of advanced maternal age (AMA) pregnancies (defined as ≥35 years) on pregnant trauma patients (PTPs) are unknown. This study compared AMA versus younger PTPs, hypothesizing AMA PTPs have increased risk of fetal delivery (FD). METHODS: A retrospective (2016-2021) multicenter study included all PTPs. Multivariable logistic regression was used to evaluate risk of FD after trauma. RESULTS: A total of 950 PTPs were included. Both cohorts had similar gestational age and injury severity scores. The AMA group had increased injuries to the pancreas, bladder, and stomach (p < 0.05). There was no difference in rate or associated risk of FD between cohorts (5.3% vs. 11.4%; OR 0.59, CI 0.19-1.88, p > 0.05). CONCLUSION: Compared to their younger counterparts, some intra-abdominal injuries (pancreas, bladder, and stomach) were more common among AMA PTPs. However, there was no difference in rate or associated risk of FD in AMA PTPs, thus they do not require increased observation.

INTRODUCTION: Trauma patients who develop indications for therapeutic anticoagulation (TAC) present a challenge due to concern for bleeding. Transfusion requirement has been described as a common complication of TAC after trauma but its clinical relevance is unclear. OBJECTIVE: Determine risk factors for and clinical outcomes associated with transfusion requirement on TAC after trauma. METHODS: All trauma patients admitted to an academic urban level I trauma center from January 2010 to August 2020 who received TAC were included in this retrospective cohort study. Data included injury characteristics; TAC indication and timing; transfusions; and interventions. Patients who required transfusion after TAC were compared to those who did not. RESULTS: Eighty-two patients were included. The most common reasons for TAC were deep vein thrombosis (67.1%) and pulmonary embolism (31.7%). Two (2.4%) patients developed gastrointestinal bleeding. One (1.2%) underwent endoscopic intervention. Two patients (4.9%) had intracranial hemorrhage progression. Blood transfusion after TAC initiation was required in 43.9% of patients. Patients who were transfused started TAC more quickly after traumatic injury (5.5 vs 10.0 days, P = .03), had fewer hospital-free days (54 vs 64 days, P < .01), ICU-free days (8.5 vs 16.5 days, P = .01), and higher mortality (13.9% vs 2.1%, P = .04). CONCLUSION: Transfusions are common after starting TAC in trauma patients. Requiring transfusion after starting TAC was associated with shorter time from injury to starting TAC, higher mortality, and fewer ICU and hospital-free days.

INTRODUCTION: Although indications and outcomes for trauma patients who require resuscitative thoracotomies are well studied, little is known about how prehospital chest compressions support survival in patients who do not meet criteria for subsequent resuscitative thoracotomy. METHODS: Data from a single institutional retrospective review of trauma patients who required prehospital chest compressions from 1/2015 to 12/2020 were collected. Patients who underwent compressions only were compared to those who underwent subsequent resuscitative thoracotomy. The primary outcome was in-hospital mortality. RESULTS: Fifty-two patients were identified, 22 of whom underwent compressions only and 30 of whom went on to undergo thoracotomy. Patients who underwent compressions only were more likely to be female (36% vs 10%, P = .04), older (mean 46 vs 35 years, P = .04), and to experience blunt trauma (78% vs 43%, P = .01). Injury severity score was similar between the cohorts (mean 18 vs 28, P = .11). One patient in the compressions only cohort had a REBOA placed compared to two in the thoracotomy cohort (1.9% vs 3.67%, P > .99). Return of spontaneous circulation (ROSC) was achieved in 17% of the compressions only cohort compared to 45% of the thoracotomy cohort (P = .03). In-hospital mortality in the compressions only cohort was 100%, whereas in-hospital mortality in the thoracotomy cohort was 94% (P = .50), with a mean of zero survival days in both groups (P = .33). CONCLUSION: Prehospital chest compressions without thoracotomy were uniformly fatal, even if transient ROSC was obtained. Our findings support termination of chest compressions for those trauma patients who do not meet criteria for resuscitative thoracotomy.

BACKGROUND: Bleeding from pelvic fractures can result in a high mortality rate unless quickly triaged by the trauma surgeon. Upon presentation, pelvic radiography may identify fractures that require angiography with possible embolization. We sought to address which fracture patterns seen on initial x-ray are associated with extravasation on angiography. METHODS: Data from a single institution retrospective review were collected on trauma patients admitted from 2011 to 2018 with pelvic fractures that required angiography. These fractures were identified by initial pelvic x-ray in the trauma bay and include anteroposterior compression (APC), lateral compression (LC), vertical shear (VS), and combined mechanism (CM) fractures, which are graded by severity. Fracture patterns high risk for bleeding, defined as APC II, APC III, LC III, VS, and CM, were compared to low-risk fracture patterns. RESULTS: Of the patients reviewed, 28 underwent pelvic angiography, 16 (57%) of which had extravasation. The difference in the incidence of extravasation between high and low-risk fracture patterns did not reach significance (36% vs 79%, P = .05). When comparing patients with acetabular fractures to those without, there was a significantly higher rate of extravasation associated with acetabular fractures (89% vs 42%, P value = .04), which were more likely to occur with LC I fractures (56% vs 11%, P = .02). CONCLUSION: Our data suggest that traditional pelvic fracture patterns may overestimate the presence of extravasation. Acetabular fractures had a high rate of extravasation, suggesting that these fractures should be considered for early angiography with possible embolization when clinically warranted.

BACKGROUND: Traumatic brain injury (TBI) results in an elaborate systemic cascade of secondary injury elicited in part by an intrinsic catecholamine response, which ultimately leads to changes in inflammation and coagulopathy. Attenuation of this catecholamine response with agents such as propranolol confers a survival advantage. The related impact of propranolol on venous thromboembolism (VTE) after TBI is largely unknown. STUDY DESIGN: A single institution retrospective review was conducted of all TBI patients requiring intensive care unit (ICU) admission with an injury severity scale (ISS) ≥ 25 from January 2013 to May 2015. Patients who received at least one dose of propranolol within 24 hours of admission (PROP) were compared to patients who did not receive any doses of propranolol (NPROP) during their hospitalization. RESULTS: Of the 131 patients analyzed, 31 (23.7%) patients received propranolol. The PROP cohort was more severely injured overall (ISS 29 vs 26.5, P = .02). While unadjusted VTE rates were similar (16.1% vs 19.0%, P = .72), the adjusted VTE rate was lower in the PROP cohort (AOR 0.20 (95% CI 0.04-0.97), adjusted P-value < .05). CONCLUSION: Propranolol use in TBI patients who have sustained critical injuries may mitigate the risk of VTE. The mechanism by which this outcome is achieved requires further investigation.

BACKGROUND: Motocross-related injury patterns and outcomes are poorly understood. The purpose of this analysis was to characterize the epidemiology, injury patterns, and outcomes of motocross collisions. These parameters were compared with motorcycle collisions for context. METHODS: The National Trauma Databank (NTDB) (2007-14) was used to identify and compare injured motorcycle and motocross riders. Variables extracted were demographics, Abbreviated Injury Scale for each body area, Injury Severity Score, and emergency department vital signs. Outcomes included mortality, ventilation days, intensive care unit length of stay, and hospital length of stay. RESULTS: Of the 5,774,836 NTDB patients, 141,529 were involved in motocross or motorcycle collisions (31,252 motocross and 110,277 motorcycle). Overall, 94.4% were drivers and 87.4% were male. Motocross riders were younger (23 vs. 42, p < 0.001), more likely to use helmets (68.9% vs. 54.1%, p < 0.001), and less likely to have used alcohol (8.4% vs. 23.0%, p < 0.001). Head and chest injuries were less common in motocross patients (28.6% vs. 37.2%, p < 0.001; 25.5% vs. 37.7%, p < 0.001, respectively), as were Injury Severity Score of greater than 15 and Glasgow Coma Scale of less than or equal to 8 (18.2% vs. 28.1%, p < 0.001; 3.7% vs. 7.7%, p < 0.001, respectively). Overall mortality was significantly lower in the motocross group (0.3% vs. 1.4%, p < 0.001). Stepwise logistic regression analysis identified age of older than 60 years, Glasgow Coma Scale of less than or equal to 8, hypotension on admission, head Abbreviated Injury Scale of greater than or equal to 3, and riding a motorcycle, either as a driver or passenger, to be independent predictors of mortality. Subgroup analysis revealed being a motocross driver or passenger to be an independent predictor of improved survival (odds ratio [OR], 0.458; 95% confidence interval [CI], 0.359-0.585; p < 0.001 and OR, 0.127; CI 95%, 0.017-0.944; p = 0.044, respectively). Helmets were protective against mortality for all patients (OR, 0.866; 95% CI, 0.755-0.992; p = 0.039). CONCLUSION: Motocross and motorcycle collisions are distinct mechanisms of injury. Motocross riders are younger, more likely to wear protective devices, and less likely to use alcohol. Motocross collisions are associated with better outcomes compared with motorcycle collisions. Wearing a helmet is associated with improved survival for all riders. LEVEL OF EVIDENCE: Retrospective epidemiological study, level IV.

OBJECTIVE: Offering undergraduate students research opportunities may enhance their interest in pursuing a surgical career and lead to increased academic productivity. We characterize the benefits of participating in the Trauma Research Associates Program. DESIGN: A 19-point Web-based survey. SETTING: Academic Level I Trauma Center. PARTICIPANTS: A total of 29 active and former members of the Trauma Research Associates Program. MAIN OUTCOME MEASURE(S): Academic activities and predictors associated with interest in a surgical career and research productivity. RESULTS: Surveys were completed on 26 of 29 (90%) participants. Clinical experience was the most highly ranked motivation to join the program (65%), followed by pursuing a research experience (46%). During their involvement, 73% of participants observed surgical intensive care unit rounds, 65% observed acute care surgery rounds, and 35% observed a surgical procedure in the operating room. In addition, 46% submitted at least one abstract to a surgical meeting coauthored with the Division's faculty. Furthermore, 58% reported that they enrolled in a medical school, whereas 17% pursued a full-time research job. The program influenced the interest in a surgical career in 39% of all members, and 73% reported that they would incorporate research in their medical career. Observing a surgical procedure was independently associated with development of a high interest in a surgical career (adjusted odds ratio: 6.50; 95% CI: 1.09, 38.63; p = 0.04), whereas volunteering for more than 15 hours per week predicted submission of at least 1 abstract to a surgical conference by the participant (adjusted odds ratio: 13.00; 95% CI: 1.27, 133.29; p = 0.03). CONCLUSIONS AND RELEVANCE: Development of a structured research program for undergraduate students is beneficial to both the participants and sponsoring institution. Undergraduate exposure to academic surgery enhances interest in pursuing a surgical specialty and leads to academic productivity.

BACKGROUND: Thrombocytosis following splenectomy is a common occurrence. Whether this thrombocytosis leads to a higher risk for venous thromboembolism (VTE) remains unclear. This investigation aimed to determine if splenectomy increases the risk for VTE. METHODS: This was a prospective study conducted in the SICU between 1/2011 and 11/2013 investigating the VTE risk in patients undergoing a splenectomy compared with those undergoing any other abdominal procedure. RESULTS: In total 2503 patients were admitted to the SICU: 37 (2%) after a splenectomy and 638 (26%) after any other abdominal surgery. Splenectomy patients had a higher incidence of VTE compared to patients undergoing any other abdominal procedure (29.7% vs. 12.1%, p < 0.01). After adjustment, splenectomy was associated with a higher adjusted risk for VTE compared to the no-splenectomy group (AOR [95% CI]: 2.6 [1.2, 5.9], p = 0.02). Reactive thrombocytosis did not predict the development of VTE. CONCLUSION: Splenectomy increases the risk for VTE, however reactive thrombocytosis is not associated with this higher incidence. Further investigations are required to characterize the pathophysiologic mechanisms of VTE development following splenectomy.

PURPOSE: The purpose of this study is to determine the effect of postoperative fluid balance (FB) on subsequent outcomes in acute care surgery (ACS) patients admitted to the surgical intensive care unit (ICU). MATERIAL AND METHODS: Acute care surgery patients admitted to the surgical ICU from 06/2012 to 01/2013 were followed up prospectively. Patients were stratified by FB into FB-positive (+) and FB-negative (-) groups by surgical ICU day 5 or day of discharge from the surgical ICU. RESULTS: A total of 144 ACS patients met inclusion criteria. Although there was no statistically significant difference in crude mortality (11% for FB [-] vs 15.5% for FB [+]; P=.422], after adjusting for confounding factors, achieving an FB (-) status by day 5 during the surgical ICU stay was associated with an almost 70% survival benefit (adjusted odds ratio [95% confidence interval], 0.31 [0.13, 0.76]; P=.010). In addition, achieving a fluid negative status by day 1 provided a protective effect for both overall and infectious complications (adjusted odds ratio [95% confidence interval], 0.63 [0.45, 0.88]; P=.006 and 0.64 [0.46, 0.90]; P=.010, respectively). CONCLUSIONS: In a cohort of critically ill ACS patients, achieving FB (-) status early during surgical ICU admission was associated with a nearly 70% reduction in the risk for mortality.

BACKGROUND: Inflammatory bowel disease is associated with a higher risk for venous thromboembolism (VTE). Whether Clostridium difficile infection similarly increases this risk is unknown. METHODS: This was a retrospective analysis of patients admitted to the surgical intensive care unit (ICU) at the Cedars-Sinai Medical Center from February 2011 to July 2013. The 2 groups were compared using standard statistical methodology. RESULTS: During the 30-month study period, a total of 1,728 patients were admitted to the surgical ICU. A total of 64 patients (3.7%) tested positive for C. difficile. The use of chemical prophylaxis for VTE was significantly higher in the C. difficile group (64.1% vs 46.2%, P = .005). Nonetheless, C. difficile patients had a higher risk for development of a VTE (23.4% vs 11.0%, adjusted odds ratio [95% confidence interval]: 1.87 [1.01 to 3.48], P = .048). In a forward logistic regression model, C. difficile was found to be independently associated with the development of VTE (adjusted odds ratio [95% confidence interval]: 1.87 [1.00 to 3.47], P = .049). CONCLUSIONS: C. difficile infection increases the risk for VTE in surgical patients admitted to the ICU.
