We hypothesized that patients with pelvic fractures and hemorrhage admitted during daytime hours were undergoing interventional radiology (IR) earlier than those admitted at night and on weekends, ...thereby establishing two standards of time to hemorrhage control.
The trauma registry (January 2008 to December 2011) was reviewed for patients admitted with pelvic fractures, hemorrhagic shock, and transfusion of at least 1 U of blood. The control group (DAY) was admitted from 7:30 AM to 5:30 PM Monday to Friday, while the study group (after hours AHR) was admitted from 5:30 PM to 7:30 AM, on weekends or holidays.
A total of 191 patients met the criteria (45 DAY, 146 AHR); 103 died less than 24 hours and without undergoing IR (29% DAY group vs. 62% AHR, p < 0.001). Sixteen patients (all in AHR group) died while awaiting IR (p = 0.032). Eighty-eight patients (32 DAY, 56 AHR) survived to receive IR. Among these, the AHR group were younger (median, 30 years vs. 54 years; p = 0.007), more tachycardic (median pulse, 119 beats/min vs. 90 beats/min; p = 0.001), and had more profound shock (median base, -10 vs. -6; p = 0.006) on arrival. Time from admission to IR (median, 301 minutes vs. 193 minutes; p < 0.001) and computed tomographic scan to IR (176 minutes vs. 87 minutes, p = 0.011) were longer in the AHR group. There was no difference in the 30-day mortality by univariate analysis. However, after controlling for age, arrival physiology, injury severity, and degree of shock, the AHR group had a 94% increased risk of mortality.
The current study demonstrated that patients admitted at night and on weekends have a significant increase in time to angioembolization compared with those arriving during the daytime and during the week. Multivariate regression noted that AHR management was associated with an almost 100% increase in mortality. While this is a single-center study and retrospective in nature, it suggests that we are currently delivering two standards of care for pelvic trauma, depending on the day and time of admission.

Identifying predictors of mortality and surgical complications has led to outcome improvements for a variety of surgical conditions. However, similar work has yet to be done for factors affecting ...outcomes of emergency general surgery (EGS). The objective of this study was to determine the predictors of in-hospital complications and mortality among EGS patients.
The Nationwide Inpatient Sample (2003-2011) was queried for patients with conditions encompassing EGS as determined by the American Association for Surgery of Trauma, categorizing them into predefined EGS groups using DRG International Classification of Diseases-9th Rev.-Clinical Modification codes. Primary outcomes considered included incidence of a major complication (pneumonia, pulmonary emboli, urinary tract infections, myocardial infarctions, sepsis, or septic shock) and in-hospital mortality. Separate multivariate logistic regression analyses for complications and mortality were performed to identify risk factors of either outcome from the following domains: patient demographics (age, sex, insurance type, race, and income quartile), comorbidities, and hospital characteristics (location, teaching status, and bed size).
This study included 6,712,151 discharge records, weighted to represent 32,910,446 visits for EGS conditions. Mean age was 58.50 (19.74) years; slightly more than half (54.66%) were female. Uninsured patients were more likely to die (odds ratio,1.25; 95% confidence interval, 1.20-1.30), whereas patients in the highest income quartile had the least likelihood of mortality (odds ratio, 0.86; 95% confidence interval, 0.84-0.87). Old age was an independent predictor of mortality for all EGS subdiagnoses. The overall mortality rate was 1.76%; the overall complication rate was 10.03%. Of the patients who died, 62% experienced at least one major complication. Patients requiring resuscitation had the highest likelihood of mortality followed by patients with vascular disease and hepatic disease.
Death patterns of EGS patients were discerned using an administrative data set. Understanding patterns of mortality and complications derived from studies such as this could improve hospital benchmarking for EGS, akin to trauma surgery's previous success.
Prognostic and epidemiologic study, level III.
Background We hypothesize that lack of access to care results in propensity toward emergent operative management and may be an important factor in worse outcomes for the uninsured population. The ...objective of this study is to investigate a possible link to worse outcomes in patients without insurance who undergo an emergent operation. Methods A retrospective cross-sectional analysis was performed using the Nationwide Inpatient Sample (NIS) 2005–2011 dataset. Patients who underwent biliary, hernia, and colorectal operations were evaluated. Multivariate analyses were performed to assess the associations between insurance status, urgency of operation, and outcome. Covariates of age, sex, race, and comorbidities were controlled. Results The uninsured group had greatest odds ratios of undergoing emergent operative management in biliary (OR 2.43), colorectal (3.54), and hernia (3.95) operations, P < .001. Emergent operation was most likely in the 25- to 34-year age bracket, black and Hispanic patients, men, and patients with at least one comorbidity. Postoperative complications in emergencies, however, were appreciated most frequently in the populations with government coverage. Conclusion Although the uninsured more frequently underwent emergent operations, patients with coverage through the government had more complications in most categories investigated. Young patients also carried significant risk of emergent operations with increased complication rates. Patients with government insurance tended toward worse outcomes, suggesting disparity for programs such as Medicaid. Disparity related to payor status implies need for policy revisions for equivalent health care access.
Abstract Background Most literature regarding fireworks injuries are from outside the United States, whereas US-based reports focus primarily on children and are based on datasets which cannot ...provide accurate estimates for subgroups of the US population. Methods The 2006–2010 Nationwide Emergency Department Sample was used to identify patients with fireworks injury using International Classification of Diseases , Ninth Revision , Clinical Modification external cause of injury code E923.0. International Classification of Diseases , Ninth Revision , Clinical Modification diagnosis codes were examined to determine the mechanism, type, and location of injury. Sampling weights were applied during analysis to obtain US population estimates. Results There were 25,691 emergency department visits for fireworks-related injuries between 2006 and 2010. There was no consistent trend in annual injury rates during the 5-y period. The majority of visits (50.1%) were in patients aged <20 y. Most injuries were among males (76.4%) and were treated in hospitals in the Midwest and South (42.0% and 36.4%, respectively) than in the West and Northeast (13.3% and 8.3%, respectively) census regions. Fireworks-related injuries were most common in July (68.1%), followed by June (8.3%), January (6.6%), December (3.4%), and August (3.1%). The most common injuries (26.7%) were burns of the wrist, hand, and finger, followed by contusion or superficial injuries to the eye (10.3%), open wounds of the wrist, hand, and finger (6.5%), and burns of the eye (4.6%). Conclusions Emergency department visits for fireworks injuries are concentrated around major national holidays and are more prevalent in certain parts of the country and among young males. This suggests that targeted interventions may be effective in combating this public health problem.
Background Historic improvements in operative trauma care have been driven by war. It is unknown whether recent battlefield innovations stemming from conflicts in Iraq/Afghanistan will follow a ...similar trend. The objective of this study was to survey trauma medical directors (TMDs) at level 1–3 trauma centers across the United States and gauge the extent to which battlefield innovations have shaped civilian practice in 4 key domains of trauma care. Methods Domains were determined by the use of a modified Delphi method based on multiple consultations with an expert physician/surgeon panel: (1) damage control resuscitation (DCR), (2) tourniquet use, (3) use of hemostatic agents, and (4) prehospital interventions, including intraosseous catheter access and needle thoracostomy. A corresponding 47-item electronic anonymous survey was developed/pilot tested before dissemination to all identifiable TMD at level 1–3 trauma centers across the US. Results A total of 245 TMDs, representing nearly 40% of trauma centers in the United States, completed and returned the survey. More than half ( n = 127; 51.8%) were verified by the American College of Surgeons. TMDs reported high civilian use of DCR: 95.1% of trauma centers had implemented massive transfusion protocols and the majority (67.7%) tended toward 1:1:1 packed red blood cell/fresh-frozen plasma/platelets ratios. For the other 3, mixed adoption corresponded to expressed concerns regarding the extent of concomitant civilian research to support military research and experience. In centers in which policies reflecting battlefield innovations were in use, previous military experience frequently was acknowledged. Conclusion This national survey of TMDs suggests that military data supporting DCR has altered civilian practice. Perceived relevance in other domains was less clear. Civilian academic efforts are needed to further research and enhance understandings that foster improved trauma surgeon awareness of military-to-civilian translation.
Studies have demonstrated that relative value units (RVUs) do not appropriately reflect cognitive effort or time spent in patient care, but RVU continues to be used as a standardized system to track ...productivity. It is unknown how well RVU reflects the effort of acute care surgeons. Our objective was to determine if RVUs adequately reflect increased surgeon effort required to treat emergent versus elective patients receiving similar procedures.
A retrospective analysis using The American College of Surgeons' National Surgical Quality Improvement Program 2011 data set was conducted. The control group consisted of patients undergoing elective colectomy, hernia repair, or biliary procedures as identified by Current Procedural Terminology. Comparison was made to emergent cases after being stratified to laparoscopic or open technique. Generalized linear models and logistic regression were used to assess specific outcomes, controlling for demographics and comorbidities of interest. The RVUs, operative time, and length of stay (LOS) were primary variables, with major/minor complications, mortality, and readmissions being evaluated as the relevant outcomes.
A total of 442,149 patients in the National Surgical Quality Improvement Program underwent one of the operative procedures of interest; 27,636 biliary (91% laparoscopic; 8.5% open), 28,722 colorectal (40.3% laparoscopic, 59.7% open), and 31,090 hernia (26.6% laparoscopic, 73.4% open) operations. Emergent procedures were found to have average RVU values that were identical to their elective case counterparts. Complication rates were higher and LOS were increased in emergent cases. Odds ratios for complications and readmissions in emergent cases were twice those of elective procedures. Mortality was skewed toward emergent cases.
Our data indicate that the emergent operative management for various procedures is similarly valued despite increased LOS, more complications, higher mortality risk, and subsequently increased physician attention. Our findings suggest that the RVU system for acute care surgeons may need to be reevaluated to better capture the additional work involved in emergent patient care.
Background Recent studies suggest there are gender-specific differences in injury response that may be related to coagulation. The objective of this study was to test the hypothesis that rapid ...thrombelastography (rTEG) coagulation profiles differ by gender. Methods Adult trauma patients were prospectively followed at 3 level 1 trauma centers over a 14-month period. rTEG was obtained upon arrival and serially at several time points during the hospital stay. Female patients were stratified into premenopausal (≤50 years) and postmenopausal (>50 years) age groups with age-matched male cohorts. Values were analyzed using a repeated-measures multilevel linear model to evaluate the effect of gender on coagulation. Results A total of 795 patients had serial rTEG data (24% female and 76% male). Compared with age-matched males, premenopausal females were more hypercoagulable by rTEG on admission ( P < .001) and for the first 12 hours after arrival. Gender was an effect modifier for alpha angle ( P = .02) and maximum amplitude ( P = .04). Controlling for Injury Severity Score and mechanism of injury, age-matched males had a >4-fold increased risk of hypercoagulable complications than premenopausal females (odds ratio, 4.7; P = .038). Conclusion This prospective, multicenter study demonstrates that premenopausal females are relatively hypercoagulable compared with age-matched males early after injury. However, this did not translate into higher thromboembolic complications.
Health care providers are increasingly focused on cost containment. One potential target for cost containment is in-hospital management of acute cholecystitis. Ensuring cholecystectomy within 24 ...hours for cholecystitis could mitigate costs associated with longer hospitalizations. We sought to determine the cost consequences of delaying operative management.
The Nationwide Inpatient Sample (2003-2011) was queried for adult patients (≥16 years) who underwent laparoscopic cholecystectomy for a primary diagnosis of acute cholecystitis. Patients who underwent open procedures or endoscopic retrograde cholangiopancreatography were excluded. Generalized linear models (GLMs) were used to analyze costs for each day's delay in surgery. Multivariable analyses adjusted for patient demographics, hospital descriptors, Charlson comorbidity index, mortality, and length of stay.
We analyzed 191,032 records. Approximately 65% of the patients underwent surgery within 24 hours of admission. The average cost of care for surgery on the admission day was $11,087. Costs disproportionately increased by 22% on the second hospital day ($13,526), by 37% on the third day ($15,243), by 52% on the fourth day ($16,822), by 64% on the fifth day ($18,196), by 81% on the sixth day ($20,125), and by 100% on the seventh day ($22,250) when compared with the cost of care for procedures performed within 24 hours of admission. Subset analysis of patients discharged 24 hours or earlier from the time of surgery demonstrated similar trends.
After controlling for patient- and hospital-related factors, we noted significant costs associated with each day's delay in operative management. Cost containment practices for acute cholecystitis justify consideration of same-day or next-day surgery where the diagnosis is straightforward.
Economic and value-based analysis, level III.
Abstract Background In the United States, approximately 800,000 cholecystectomies are performed annually. We sought to determine the influence of preoperative smoking on postcholecystectomy wound ...complication rates. Materials and methods Using the National Surgical Quality Improvement Program database (2005–2011), patients aged ≥18 y who underwent elective open or laparoscopic cholecystectomy (LC) for benign gallbladder disease were identified using current procedural terminology codes. Multivariate regression was performed to determine the association between smoking status and wound complications, by surgical approach. Results Of 143,753 identified patients, 128,692 (89.5%) underwent LC, 27,788 (19.3%) were active smokers, and 100,710 (70.2%) were females. Active smokers were younger than nonsmokers (mean + standard deviation age: 44.2 (14.9) versus 51.6 (17.9) years); P < 0.001) and had fewer comorbidities. Within 30-d postcholecystectomy, wound complications were reported in 2011 (1.4%) patients. Compared with nonsmokers, active smokers demonstrated increased odds of wound complications after both open cholecystectomy (odds ratio 1.28; P = 0.010) and LC (odds ratio 1.20; P = 0.020) after adjustment for demographic and clinical characteristics. Having wound complications increased the average postoperative length of stay by 2–4 d ( P <0.001). Conclusions Active smokers are more likely to develop wound complications after cholecystectomy, regardless of surgical approach. Occurrence of wound complications consequently increases postoperative length of stay. Smoking abstinence before cholecystectomy may reduce the burden associated with wound complications.
