Anastomotic leak is the most dreaded complication following colonic resection. While patient frailty is increasingly being recognized as a risk factor for surgical morbidity and mortality, the current colorectal body of literature has not assessed the relationship between frailty and anastomotic leak.Evaluate the relationship between patient frailty and anastomotic leak as well as patient frailty and failure to rescue in patients who experienced an anastomotic leak.Retrospective cohort study.American College of Surgeons National Surgical Quality Improvement Program Database from 2015 to 2017.Patients with the diagnosis of colonic neoplasia undergoing an elective colectomy during the study time period.Anastomotic leak, failure to rescue.A total of 30,180 elective colectomies for neoplasia were identified. The leak rate was 2.9% (n = 880). Compared to nonfrail patients, frail patients were at increased odds of anastomotic leak (frailty score = 1: OR 1.34, 95% CI 1.10-1.63; frailty score = 2: OR 1.32, 95% CI 1.04-1.68; frailty score = 3: OR = 2.41, 95% CI 1.47-3.96). After an anastomotic leak, compared to nonfrail patient, a greater proportion of frail patients experienced mortality (3.4% vs 5.9%), septic shock (16.1% vs 21.0%), myocardial infarction (1.1% vs 2.9%), and pneumonia (6.8% vs 11.8%). Furthermore, the odds of mortality, septic shock, myocardial infarction, and pneumonia increased in frail patients with higher frailty scores.Potential misclassification bias from lack of a strict definition of anastomotic leak and retrospective design of the study.Frail patients undergoing colectomy for colonic neoplasia are at increased risk of an anastomotic leak. Furthermore, once a leak occurs, they are more vulnerable to failure to rescue.

La tasa de fuga fue del 2,9% (n = 880). En comparación con los pacientes no frágiles, los pacientes frágiles tenían mayores probabilidades de fuga anastomótica para (puntuación de fragilidad = 1: OR = 1,34, IC del 95%: 1,10-1,63; puntuación de fragilidad = 2: OR = 1,32, IC del 95%: 1,04- 1,68; puntuación de fragilidad = 3: OR 2,41; IC del 95%: 1,47-3,96). Después de una fuga anastomótica, en comparación con un paciente no frágil, una mayor proporción de pacientes frágiles experimentó mortalidad (3,4% frente a 5,9%), choque séptico (16,1% frente a 21,0%), infarto de miocardio (1,1% frente a 2,9%) y neumonía (6,8% vs 11,8%). Además, las probabilidades de mortalidad, choque séptico, infarto de miocardio y neumonía aumentaron en pacientes frágiles con puntuaciones de fragilidad más altas.LIMITACIONES:Posible sesgo de clasificación errónea debido a la falta de una definición estricta de fuga anastomótica, diseño retrospectivo del estudio.CONCLUSIÓN:Los pacientes frágiles sometidos a colectomía por neoplasia de colon tienen un mayor riesgo de una fuga anastomótica. Además, una vez que ocurre una fuga, son más vulnerables a fallas en el rescate. Consulte Video Resumen en http://links.lww.com/DCR/B784.

In order to better characterize outcomes of palliative surgery (PS), we evaluated patients that experienced top quartile survival to elucidate predictors of high impact PS.All PS performed on advanced cancer patients from 2003 to 2017 were identified from a PS database.167 patients were identified. Multivariate analysis demonstrated the ability to rise from a chair was independently associated with top quartile survival (HR 7.61, 95% CI 2.12-48.82, p=0.008) as was the need for re-operation (HR 2.81, 95% CI 1.26-6.30, p=0.0012). Patients who were able to rise from a chair had significantly prolonged overall survival (320 vs 87 days, p 0.001).Although not the primary goal, long-term survival can be achieved following PS and is associated with re-operation and the ability to rise from a chair. These patients experience the benefits of PS for a longer period of time, which in turn maximizes value and positive impact.Long-term survival and symptom control can be achieved in highly selected advanced cancer patients following palliative surgery. The ability of the patient to independently rise from a chair and the provider to offer a re-operation when indicated are associated with long-term survival following a palliative operation.

IntroductionInhalation injuries carry significant acute care burden including prolonged ventilator days and length of stay. However, few studies have examined post-acute outcomes of inhalation injury survivors. This study compares the long-term outcomes of burn survivors with and without inhalation injury.MethodsData collected by the Burn Model System National Database from 1993 to 2019 were analyzed. Demographic and clinical characteristics for adult burn survivors with and without inhalation injury were examined. Outcomes included employment status, Short Form-12/Veterans Rand-12 Physical Composite Score (SF-12/VR-12 PCS), Short Form-12/Veterans Rand-12 Mental Composite Score (SF-12/VR-12 MCS), and Satisfaction With Life Scale (SWLS) at 24 months post-injury. Regression models were used to assess the impacts of sociodemographic and clinical covariates on long-term outcome measures. All models controlled for demographic and clinical characteristics.ResultsData from 1,871 individuals were analyzed (208 with inhalation injury; 1,663 without inhalation injury). The inhalation injury population had a median age of 40.1 years, 68.8% were male, and 69% were White, non-Hispanic. Individuals that sustained an inhalation injury had larger burn size, more operations, and longer lengths of hospital stay (pConclusionsBurn survivors with inhalation injury were significantly less likely to be employed at 24 months post-injury compared to survivors without inhalation injury. However, other health-related quality of life outcomes were similar between groups. This study suggests distinct long-term outcomes in adult burn survivors with inhalation injury which may inform future resource allocation and treatment paradigms.

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.

Flame injuries are the primary cause of burns in young adults. Although drug and alcohol intoxication has been associated with other types of trauma, its role in burn injury has not been well described in this population. The purpose of this study was to investigate the association of intoxication and flame burn injuries in young adults in the United States. The 2014 Nationwide Emergency Department Sample was queried for burn injury visits of young adult patients, 13-25 years old. This data is weighted to allow for national estimates. Burn mechanism and intoxication status were determined by International Classification of Diseases, Ninth Revision codes. Multivariable logistic regression analysis was used to assess the association of intoxication and emergency department (ED) visits due to flame burns, adjusting for patient age, gender, zip code median income, zip code rural-urban designation, timing of visit, and hospital region. Further analyses assessed the odds of admission or transfer, as a possible proxy of injury severity, in patients with flame or other burns, with and without intoxication adjusting for patient age, gender, primary insurance, and hospital trauma designation. There were 20,787 visits for patients 13-25 years old with burn injuries and 12.9% (n = 2678) had a codiagnosis of intoxication. There was an increasing proportion of intoxication by age (5.8% 13-17 years old, 25% 18-20 years old, 69% 21-25 years old, P < .001). ED visits for burns with a codiagnosis of intoxication had 1.34 times ([95% confidence interval (CI): 1.18, 1.52], P < .01) higher odds of having flame burns compared to other burn mechanisms. Those with flame burns and intoxication were most likely to be admitted or transferred when compared to nonflame, nonintoxication visits in the adjusted model (odds ratio [OR] 5.49, [95% CI: 4.29, 7.02], P < .01). Furthermore, the odds of admission or transfer in visits with the combined exposure of intoxication and flame mechanism were significantly higher than visits due to nonflame burns and intoxication (OR 2.75, [2.25, 3.36], P < .01) or flame burns without intoxication (OR 3.00, [95% CI: 2.61, 3.42], P < .01). This study identified a significant association between flame-burn-related ED visits and intoxication in the young adult population in the United States. In addition, the combination of flame mechanism and intoxication appears to result in more substantial injury compared with either exposure alone. The relationship seen between intoxication and flame burn injury underscores a major target for burn prevention efforts in the young adult population.

Background Lymphocytes have become the target of cancer interventions through engineering or immune checkpoint antibodies. We previously found decreased lymphocyte counts to be a predictor of mortality and complications in trauma and cardiac surgery patients. We hypothesized lack of lymphocyte count recovery postoperatively would predict outcomes in esophagectomy patients. Methods A retrospective review of all patients undergoing esophagectomy for adenocarcinoma performed over 13 y at our center by a single surgeon after institutional review board approval was performed. Patients were grouped by postoperative lymphocytes counts: never low, low with recovery, and low without recovery. Resolution of lymphopenia was assessed by day 4. Primary end points were overall and recurrence-free survival. Results In total, 198 patients were included with a minimum 6-mo follow-up. Collectively the 5-y recurrence and overall survival rates were 36% and 50%, respectively. Recurrence was significantly higher at 5 y in patients with persistent lymphopenia (43%) compared with those who recovered (14% P = 0.0017) and those who never dropped (0% P = 0.0009). The persistent lymphopenia group had significantly lower survival (45%) compared with the two other groups (67% P = 0.0232). Conclusions There is a significant decrease in the overall and recurrence-free survival in those patients whose lymphocyte count drops without recovery after their esophagectomy. These data imply differences in immune responses to the stress of surgery that can be measured with routine postoperative laboratory values and are indicative of overall outcomes.

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.

Sepsis remains a major public health concern, characterized by marked immune dysfunction. Innate lymphoid cells develop from a common lymphoid precursor but have a role in orchestrating inflammation during innate response to infection. Here, we investigate the pathologic contribution of the group 2 innate lymphoid cells (ILC2s) in a murine model of acute septic shock (cecal ligation and puncture). Flow cytometric data revealed that ILC2s increase in number and percentage in the small intestine and in the peritoneal cells and inversely decline in the liver at 24 hours after septic insult. Sepsis also resulted in changes in ILC2 effector cytokine (IL-13) and activating cytokine (IL-33) in the plasma of mice and human patients in septic shock. Of interest, the sepsis-induced changes in cytokines were abrogated in mice deficient in functionally invariant natural killer T cells. Mice deficient in IL-13–producing cells, including ILC2s, had a survival advantage after sepsis along with decreased morphologic evidence of tissue injury and reduced IL-10 levels in the peritoneal fluid. Administration of a suppressor of tumorigenicity 2 (IL-33R) receptor–blocking antibody led to a transient survival advantage. Taken together, these findings suggest that ILC2s may play an unappreciated role in mediating the inflammatory response in both mice and humans; further, modulating ILC2 response in vivo may allow development of immunomodulatory strategies directed against sepsis.

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.

Objective Operating room simulation exercises have been well established as an effective means of improving confidence, task engagement, and learning retention among surgical residents. We have established a cost-effective model and scoring system assessing resident skills to tie secure surgical knots with minimal tension. Design A circular grid divided into 18 segments was placed underlying an aluminum can. Trainees tie 20 surgical square knots scored for time and total knot length. Movement of the can outside the grid served as a scoring penalty. Recorded were time, length of the 20 knots, and number of segments exposed at exercise end. A score was developed to identify a progression of skills with PGY level. All outcomes were compared between classes using ANOVA. Setting Brown University/Rhode Island Hospital Department of Surgery. Participants Surgical residents (PGY1-PGY5) and participating attending surgeons employed by Rhode Island Hospital. Results Knot length and exposed segments showed trends of improved scores with ascending PGY level. Only average time attained statistical significance. Overall scores improved with PGY level: PGY1 (N = 9) PGY2 (N = 3) PGY3 (N = 6) PGY4 (N = 3) PGY5 (N = 3) Attending (N = 4) Composite 100.5 116.4 152.7 138.1 169.9 162.8 Composite scores significantly improved when comparing PGY1 to PGY3, PGY5, and Attending surgeons (p = 0.016, 0.011, and 0.011, respectively). Time significantly improved when comparing PGY1 to PGY3 and Attending surgeons (77vs. 50 and 47 seconds, p = 0.019 and 0.022 respectively). Composite scores were not significantly different above PGY3. Conclusions A low fidelity, high impact knot tying model has been developed to assess the ability to securely tie surgical knots while minimizing tension, with linear increases in scores that appear to plateau at the PGY3 level.

Background Critically ill patients with sepsis and acute respiratory distress syndrome have severely altered physiology and immune system modifications. RNA splicing is a basic molecular mechanism influenced by physiologic alterations. Immune checkpoint inhibitors, such as B and T Lymphocyte Attenuator (BTLA) have previously been shown to influence outcomes in critical illness. We hypothesize altered physiology in critical illness results in alternative RNA splicing of the immune checkpoint protein, BTLA, resulting in a soluble form with biologic and clinical significance. Methods Samples were collected from critically ill humans and mice. Levels soluble BTLA (sBTLA) were measured. Ex vivo experiments assessing for cellular proliferation and cytokine production were done using splenocytes from critically ill mice cultured with sBTLA. Deep RNA sequencing was done to look for alternative splicing of BTLA. sBTLA levels were fitted to models to predict sepsis diagnosis. Results sBTLA is increased in the blood of critically ill humans and mice and can predict a sepsis diagnosis on hospital day 0 in humans. Alternative RNA splicing results in a premature stop codon that results in the soluble form. sBTLA has a clinically relevant impact as splenocytes from mice with critical illness cultured with soluble BTLA have increased cellular proliferation. Conclusion sBTLA is produced as a result of alternative RNA splicing. This isoform of BTLA has biological significance through changes in cellular proliferation and can predict the diagnosis of sepsis.

Background: The etiology of sepsis is broad. The peritoneal cavity displays compartmentalization with respect to inflammatory responses, so peripheral blood responses to sepsis of abdominal vs. non-abdominal origin are expected to be divergent. Lymphocytes and invariant natural killer T (iNKT) cells play important roles in survival from sepsis, as they dampen the neutrophil and macrophage responses. We assessed whether circulating iNKT cells display distinct phenotypic profiles depending on the presence of abdominal vs. non-abdominal infection with sepsis. Methods: Patients with sepsis, defined as infection confirmed microbiologically with a systemic inflammatory response syndrome (SIRS), were enrolled prospectively. They were categorized as having either exclusively sepsis of abdominal or exclusively non-abdominal origin. The white blood cell (WBC) count was recorded. Whole-blood staining with monoclonal antibodies to CD3, V-alpha-24 (to identify iNKT cells), and CD69 (marker of early activation) was applied. Results: Of the 53 enrolled patients, 18 had abdominal infection. Pneumonia was the most common non-abdominal type. There was no difference in gender, age, Acute Physiology and Chronic Health Evaluation (APACHE) II score, WBC count, or CD3(+) T cells (7.1%±1.6% vs. 6.5%±0.9%; p=0.75) in the two groups. Patients with abdominal infection had a higher proportion of iNKT cells (2.7%±1.1% vs. 0.89%±0.14%; p=0.032). Correcting for WBC count, this translated into a higher absolute number of iNKT cells (3.4±1.8×10(7)/L vs. 0.74±0.15×10(7)/L; p=0.03). Patients with sepsis of abdominal origin had a lower percentage of CD69(+) iNKT cells (9.1%±3.1% vs. 27.2%±5.8%; p=0.028). In patients in shock vs. those who were not, patients with non-abdominal infection exhibited a greater number of iNKT cells (1.47±0.3 v. 0.62±0.1×10(7)/L; p=0.022) and percentage of activated iNKT cells (53±14.5% vs. 17.9±4.8%; p=0.04). Patients with non-abdominal infection who died had a lower absolute number of activated iNKT cells (0.8±1.2×10(7)/L vs. 0.34±0.1×10(7)/L; p=0.023); however, no such shock or death correlation was noted in patients with sepsis of abdominal origin. Conclusions: Divergent sepsis etiologies display distinct blood iNKT cell population changes. In non-abdominal infection, this difference was associated with septic shock and death. Elucidating the importance and basis for these changes relative to the response to sources of infection will help clarify appropriate diagnosis and management of the patient with sepsis.

Background Sepsis is associated with severe immunosuppression, evidenced by loss and dysfunction of CD3 + lymphocytes and γδ-TCR + T-cells. There is limited data addressing changes in the invariant natural killer T-( i NKT) cell population with sepsis, and whether such changes correlate with clinical outcomes. Specifically, septic geriatric patients have marked mortality. How γδ-TCR + T-cells and i NKT-cells are altered in the settings of sepsis and advanced age, and how these changes correlate with mortality are unknown. Methods 49 young (18–50 years) and 55 geriatric (>65 years) ICU patients with confirmed sepsis were enrolled. Blood was stained with antibodies to detect the percentage and absolute number of CD3 + (T-cells), γδ-TCR + T-cell, TCR-Vα-24 + ( i NKT-cells), and CD69 + (marker of cell activation). Blood from 10 healthy controls was also collected. Results Septic patients displayed marked leukocytosis, decreased CD3 + lymphocytes, and γδ-TCR + T-cells, and increased percentage and number of i NKT-cells. Young and geriatric patients had similar degree of leukocytosis, along with percentage, number, and %CD69 + CD3 + T-cell and γδ-TCR + T-cells; however, percentage, number, and %CD69 + i NKT-cells were most markedly elevated in geriatric patients. Geriatric non-survivors had higher percentage and number of, but decreased %CD69 + , i NKT-cells vs survivors. Conclusions i NKT-cells are increased in sepsis, suggesting that they typify an evolving morbid state. This is most pronounced in geriatric non-survivors, a group demonstrating dysfunctional regulatory i NKT-cell phenotype.

Although nearly 18 million adults have been diagnosed as having a current alcohol abuse or dependence disorder, only 1 in 7 reports ever having received any kind of alcohol treatment (Grant et al., 2004; Cohen et al., 2007). At the same time, people with alcohol use problems are likely to be treated in trauma care centers and emergency departments (EDs) (Cohen et al., 2007) for problems related or unrelated to their alcohol use. People with alcohol-related problems are overrepresented in ED and primary care settings compared with those in the general population (Cherpitel, 1994). Furthermore, alcohol-related ED visits have increased significantly over the past 15 years (Cherpitel & Ye, 2012). Therefore, EDs provide an opportunity for screening and brief intervention for problematic alcohol use. Although it has been over three decades since a WHO Expert Committee first called for the development of methods that could be efficiently applied in primary care settings (World Health Organization, 1980), national goals for a reduction in substance-related ED visits (Healthy People 2010, U.S. Department of Health and Human Services, 2005) have not been realized (Cherpitel & Ye, 2012). A recent review (Nilsen et al., 2008) of 14 studies of brief motivational intervention (BMI) in EDs for alcohol indicates that although some studies have found that BMI reduced alcohol consumption, hazardous use of alcohol, and alcohol-related injuries (compared to usual ED care), approximately 35% of the reviewed studies found no effect (e.g. Daeppen, et al., 2007; D’Onofrio, et al., 2008). Also somewhat mixed are the results of a recent meta-analysis (Kaner et al., 2009) of 22 randomized controlled trials in primary care settings that confirmed the benefit of BMI for men but not women. Furthermore, even when positive treatment effects are reported, not all outcome measures are impacted similarly (e.g., Field et al., 2009; Monti et al., 1999). For example, past studies have identified BMI effects (i.e., group differences) in alcohol use but not in alcohol-related problems (Monti et al., 2007); others have found intervention group differences in alcohol-related problems, but not in drinking behaviors (Longabaugh et al., 2001; Monti et al., 1999). These discrepancies in results suggest the need for a more impactful approach. One possible avenue for enhancing the effects of BMI in emergency care might be to incorporate significant others (SO) into the treatment. Concerned SOs tend to be present soon after hospital admissions, and may be open to supporting their family member/friend’s behavior change. SOs can provide positive and/or negative influences on alcohol treatment process and outcome in various ways (Magill et al., 2010). For example, Havassy et al. (1991) found the social network can inhibit drinking; friends or family members can (a) provide feedback that might help motivate the problem drinker to change the drinking behavior; (b) affirm skills of the problem drinker that enhance the probability of successful change; (c) help set treatment goals; and (d) provide support for changes in drinking behavior (Miller et al., 1995a). On the negative side, an alcohol abuser’s social network is likely to include other heavy drinkers, and many will drink with their partners (e.g., Fernandez-Pol et al., 1986), which can make reducing alcohol intake or abstinence especially difficult (e.g., Havassy et al., 1991; Hunter-Reel et al., 2010), and can make it challenging to select an appropriate SO for intervention. Nevertheless, there is a basis for including SOs in brief alcohol treatment. There is a substantial literature establishing the efficacy of SO-enhanced interventions for alcohol problems (e.g., Epstein & McCrady, 1998; McCrady et al., 2009) although including SO’s in treatment does not always increase benefits (Monti, et al., 1990). Having family and friend networks that are supportive of alcohol use reduction is predictive of successful change (Longabaugh et al., 1995; Stout et al., 2012), with SO-involved alcohol interventions reliably increasing the likelihood that an at-risk drinker will initiate positive changes (O’Farrell, 1993). In a recent meta-analysis, a clear advantage was found for Behavioral Couples Treatment (BCT) over individual-based treatments for frequency and consequences of alcohol use as well as relationship satisfaction (Powers et al., 2008). Although the benefit of BCT with low severity problem drinkers has been studied less, there is some evidence for lower efficacy with these individuals (Powers et al., 2008). Miller and Rollnick (2002) support the notion that SOs are a natural support that can reinforce the identified patient’s change process. The Motivational Enhancement Therapy Manual created for Project MATCH (MET: Miller et al., 1992) suggests the inclusion of a SO in early treatment sessions to help patients resolve ambivalence regarding change. The premise was that SOs could describe alcohol-related consequences, offer support, comment on the feedback provided by the therapist, and generally contribute opinions that may be more positively received by the patient than if delivered by the therapist. Unfortunately, in Project MATCH only 17% of outpatient and 13% of aftercare MET patients elected to include SOs (Carroll et al., 1998), and only 2% did so in a subsequent study of MET (Miller et al., 2003a). Despite the number of studies examining and supporting BCT and couples treatment for alcohol use disorders, few studies incorporating SOs into motivational interviewing (MI) sessions have been conducted, and to date, such interventions have been delivered almost exclusively in individual format (cf. Cordova, et al., 2001). The efficacy of an enhanced MI that includes both the patient and a SO as a design element is unknown. Given the low rates of optional SO participation in prior research, any study designed to test the addition of SOs to MI sessions would necessarily have to require that both the patient and SO participate. It is likely that this requirement has been a deterrent to conducting this type of treatment study. Inherent difficulties and the additional work involved in recruiting appropriate SOs who are motivated to participate are indeed challenges. Nevertheless, given that SOs are often present and concerned about the patient in the hospital, recruitment and inclusion of SOs in such a study might be more successful in this “opportunistic setting.” Another variable that may influence outcomes is recruitment site. The efficacy of BMI has been studied most often in the ED, less often in the trauma unit, and very few studies have recruited patients from both sites. These treatment sites are distinct; trauma units treat more severely injured patients and over longer periods of time. Most trauma patients are hospitalized following acute treatment for the trauma; ED patients are not typically admitted to a trauma service. Both settings are appropriate for an opportunistic BMI as both provide a window of opportunity occasioned by a medical event (Field et al., 2010). Since the optimal application and practice of BIs in medical settings has been questioned (Field et al., 2010; Nilsen et al., 2009) this study enrolled patients from both sites. The objective of this study was to investigate the relative efficacy of a SO-enhanced Motivational Intervention (SOMI) compared to an Individual Motivational Intervention (IMI). Our primary aim was to test the hypothesis that patients who received SOMI would drink less alcohol and suffer fewer alcohol-related consequences in the year following their hospital visit as compared to patients assigned to IMI. Our secondary aim was to test the extent to which SOMI (compared to IMI) led to significant changes in SO behaviors related to patient drinking. Both sets of aims (primary and secondary) incorporated an exploration of the effects of intervention setting (trauma unit vs. ED) without a theoretical basis for hypothesizing any interaction.

We designed a simple, low-cost workshop to teach surgical residents the basic skills of vascular anastomosis. We studied our ability to identify objective procedural and end-product metrics that could be used to measure improvement in vascular anastomotic skill before and after training.Ten postgraduate year 2 residents without previous vascular surgery experience and four attending surgeons (expert) performed end-to-side anastomosis using a synthetic graft. The residents were taught the basic skills of vascular anastomosis during three didactic workshops. The objective metrics included volume leakage after saline perfusion (leak) and the time needed to complete the anastomosis. Penalty points were assigned for broken sutures, air knots, locking sutures, and failure to maintain an outside-in to inside-out technique. The leak, time, and penalties before and after training were compared.The mean leak was 70.4 ± 13.7 mL and the mean completion time was 18.7 ± 3 min for the pretraining group versus 45.3 ± 10.6 mL (P0.01) and 8.5 ± 1 min (P0.001), respectively, for the attending group. After training, significant improvement was seen in resident leak (46.7 ± 6.8 mL; P0.001) and completion time (14.4 ± 3 min; P0.01). Leak was similar between the post-training and expert groups (46.7 ± 6.8 mL and 45.3 ± 10.6 mL, respectively; P = 0.77); however, a significant difference for the completion time remained (14.4 ± 3.0 min and 8.5 ± 1 min, respectively; P0.01). The mean number of technical errors improved from 2.7 in the pretraining group to zero for the post-training group after completing the workshop.We have reported an easy to implement workshop for teaching surgical residents the basic skills of performing vascular anastomosis.

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.

Continued assessment and redesign of the curriculum is essential for optimal surgical education. For the last 3 y, we have asked the residents to reflect on the previous week and describe "the best thing" they learned. We hypothesize that this statement could be used to assess the weaknesses or strengths of our curriculum.Starting in 2007, residents filled out surveys approximately 4 times/y at the start of a mandatory conference. They were asked to describe the "best thing" they learned that week, where it was learned, and who taught it. Residents were not asked to classify the item learned by core competency (communication, knowledge, patient care, practice-based learning, professionalism, and systems-based practice). This categorization into core competencies was done as part of our study design. Attending, fellow, resident, or other were used as groups designating who taught each item. Where the item was learned was fit into either clinic, conference, operating room (OR), wards, or self. The impact of postgraduate year (PGY) level on learning was also assessed. χ(2) analysis was used to compare groups.During the study period, 304 surveys were completed and returned by 65 residents. The majority of responses came from PGY 1 residents (134, 43%). Patient care and knowledge were the most common core competencies learned. As PGY level increased, learning of professionalism (P = 0.035) increased. A majority of learning was experiential (wards and OR, P0.0125). Self-learning and learning in clinic was a minor component of learning (P0.0125). Learning on wards (P0.001) decreased as residents progressed and learning from the OR (P = 0.002) had the opposite trend.Patient care and knowledge are the most frequently cited competencies learned by the residents. Self-learning is not a significant source of learning, and the majority of the learning is experiential. It is not known if this was a sign that there was a lack of self-directed learning or that self-directed learning was not an efficient method of learning. In addition, each PGY level learns differently (teacher and location of learning), perhaps reflecting the different needs and/or structure of each PGY. We believe the reflective statement has been and will be a useful tool to assess our curriculum.

Background Acute respiratory distress syndrome (ARDS) remains a common organ dysfunction in the critically ill patient. Mechanisms for its development have focused on immune mediated causes, aspects of our understanding are not complete, and we lack biomarkers. Design, setting, and subjects Blood and bronchial alveolar lavage fluid (BAL) from humans (n = 10–13) with ARDS and controls (n = 5–10) as well as a murine model of ARDS (n = 5–6) with controls (n = 6–7) were studied. Methods ARDS was induced in mice by hemorrhagic shock (day 1) followed by poly-microbial sepsis (day 2). Samples were then collected on the third day after the animals were euthanized. Ex vivo experiments used splenocytes from animals with ARDS cultured with and without soluble programmed death receptor-1 (sPD-1). Results Levels of sPD-1 are increased in both the serum (11,429.3 pg/mL(SD 2133.3) vs. 8061.4(SD 4187.8), p = 0.036) and bronchial alveolar lavage (BAL) fluid (6,311.1 pg/mL(SD 3758.0) vs. 90.7 pg/mL(SD 202.8), p = 0.002) of humans with ARDS. Similar results are seen in the serum (9396.1 pg/mL(SD 1546.0) vs. 3464.5 pg/mL(SD 2511.8), p = 0.001) and BAL fluid (2891.7 pg/mL(SD 868.1) vs. 1385.9 pg/mL(SD 927.8), p = 0.012) of mice. sPD-1 levels in murine blood (AUC = 1(1–1), p = 0.006), murine BAL fluid (AUC = 0.905(0.717–1.093), p = 0.015), and human BAL (AUC = 1(1–1), p = 0.001) fluid predicted ARDS. To assess the importance of sPD-1 in ARDS, ex vivo experiments were undertaken. BAL fluid from mice with ARDS dampens the TNF-α production compared to cells cultured with BAL lacking sPD-1 (2.7 pg/mL(SD 3.8) vs. 52.38 pg/mL(SD 25.1), p = 0.002). Conclusions This suggests sPD-1 is elevated in critical illness and may represent a potential biomarker for ARDS. In addition, sPD-1 has an anti-inflammatory mechanism in conditions of marked stress and aids in the resolution of severe inflammation. sPD-1 could be used to not only diagnose ARDS, but may be a potential therapy.

Background Despite advances in perioperative care, the rate of cardiac events in vascular patients remains high. We have previously shown that infections in trauma patients are associated with higher rates of subsequent cardiac complications, likely due to the additive effect of a second hit of an infection following the trauma. The aim of this study was to investigate whether there is an association between postoperative infections and subsequent cardiac events in vascular patients. Methods A 5-year retrospective review of demographics, comorbidities, operative interventions, infectious, and cardiac events in all vascular patients who underwent an operative intervention at a single tertiary referral center was performed. In patients with clinical suspicion of myocardial injury, myocardial damage was defined as troponin >0.15 ng/mL and myocardial infarction (MI) as troponin >1 ng/mL. Pneumonia was diagnosed using bronchoalveolar lavage (BAL) and considered positive if BAL fluid culture contained >10,000 colony-forming units (cfu). Urinary tract infection (UTI) was diagnosed if the urine culture contained >100,000 cfu. All other infections were diagnosed by culture data. Regression analysis was performed to assess risk of cardiac events as a function of infections adjusting for age, gender, and comorbidities. Results We analyzed 1,835 vascular operative interventions with the mean age of the cohort 65.5 years (65.9% male). The overall infection rate was 13.2%, with UTI being the most common (60.3%). The overall rate of myocardial damage was 8.1% and the rate of MI 3.8%. Rates of both myocardial damage (15.5 vs. 7.7%; P = 0.0015) and MI (7.1 vs. 3.4%; P = 0.018) were significantly higher in patients with infections, compared to those without infections. Adjusting for age, gender, medical comorbidities, open versus endovascular cases as well as statin and steroid use, patients with UTI were more likely to subsequently develop either myocardial damage (odds ratio [OR] = 3.57 [95% confidence interval = 1.51-8.45]) or MI (OR = 4.20 [1.23-14.3]). A similar association was noted between any infections and either myocardial damage (OR = 2.97 [1.32-6.65]) or MI (OR = 4.31 [1.44-12.94]). Conclusions We herein describe an association between postoperative infections, most commonly UTI, and subsequent cardiac events. Efforts should be made to minimize the risk of developing infections to ensure cardioprotection in vascular patients during perioperative period.

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.

National and regional surgical meetings represent the key venue in which investigators present research results and a frequent source of continuing medical education for community and academic-based providers.1,2 Results from the presented research are often reprinted in the lay press, allowing results to reach thousands more nonattendees and in some cases, the public. Because of this potential for such “high-profile” dissemination, research selected for presentation should be of the highest scientific merit and research quality. Despite this, abstracts submitted to societal meetings typically do not undergo the same critical peer review as published manuscripts. Many academic societies do not have formal qualifications for abstract reviewers nor do they publish standardized reviewing or selection criteria. The most frequently used quality measure of a meeting’s scientific merit has been the number of abstracts presented that go on to peer-reviewed publication. A number of authors have described the publication rates for abstracts presented at national and international meetings, reporting proportions of 23% to 55% with publication delays of 12 months to 28 months.3–5 It is possible that these low publication rates indicate a lack of methodological quality in presented abstracts that do not ultimately stand up to peer review. Rather than basing abstract acceptance on methodological quality, other criteria, such as institutional affiliation and authorship, may play a role in selection. In addition, it is possible that particularly “hot” clinical topics are preferentially selected without particular attention to research methodology. A lack of methodological scrutiny can provide seriously flawed research the opportunity to attain a high-profile platform. It is also possible that such flaws are detected in manuscript review and result in the work not being published. We sought to describe the level of methodological detail reported in the abstracts presented at a major, national and international surgical meeting. We hypothesized that accepted abstracts would rate high on the key methodological factors selected and we further hypothesized that oral presentations would rate higher than poster presentations.

Obese women who become pregnant face many health risks, including gestational diabetes, pregnancy-induced hypertension, and pre-eclampsia. These women also have a greater incidence of preterm labor, cesarean sections, and perioperative morbidity. Infants born to obese women have increased rates of macrosomia and congenital anomalies, as well as life-long complications such as obesity and its associated morbidities. With the increase in numbers of weight loss operations being performed in women of child-bearing age, physicians will have to address patient concerns regarding the safety of pregnancy after surgery. Many of the proposed health benefits of weight loss after surgery could translate to decreased rates of complications experienced by obese pregnant women. Case reports and small series have emerged documenting pregnancy courses after bariatric surgery. We reviewed the studies that reported pregnancy outcomes compiled from PubMed and Ovid databases to help draw conclusions regarding the maternal, fetal, and infant safety in women after bariatric surgery. The observations from these studies have shown that the health risks experienced by obese women during pregnancy are reduced after weight loss surgery. Additionally, there does not appear to be any increased risk regarding fetal or infant outcome.

Multiple studies have shown the significantly increased post-operative morbidity and mortality of patients undergoing palliative operations. It has been proposed by some authors that the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database can be used reliably to develop risk-calculators or as an aid for clinical decision-making in advanced cancer patients. ACS-NSQIP is a population-based database that by design only captures outcomes data for the first 30-day following an operation. We considered the suitability of these data as a tool for decision-making in the advanced cancer patient.Six-year retrospective review of a single institution's ACS-NSQIP database for cases identified as "Disseminated Cancer". Procedures performed with palliative intent were identified and analyzed.Of 7,763 patients within the ACS-NSQIP database, 138 (1.8%) were identified as having "Disseminated Cancer". Of the remaining 7,625 entries only 4,486 contained complete survival data for analysis. Thirty-day mortality within the "Disseminated Cancer" group was higher when compared to all other surgical patients (7.9% vs. 0.9%, P0.001). Explicit chart review of these 138 patients revealed that 32 (23.2%) had undergone operations with palliative intent. Overall survival for palliative and non-palliative operations was significantly different (104 vs. 709 days, P0.001). When comparing palliative to non-palliative procedures using ACS-NSQIP data, we were unable to detect a difference in 30-day mortality (9.4% vs. 7.5%, P=0.72).Calculations utilizing ACS-NSQIP data fail to demonstrate the increased mortality associated with palliative operations. Patients diagnosed with advanced cancer are not adequately represented within the database due to the limited number of cases collected. Also, more suitable outcomes measures for palliative operations such as pain relief, functional status, and quality of life, are not captured. Therefore, the sole use of thirty-day morbidity and mortality data contained in the ACS-NSQIP database is insufficient to make sound decisions for surgical palliation.

Odontoid fractures are the most common cervical spine fractures in elderly patients. Treatment options included operative fixation (OP) or nonoperative management with either a halo-vest (HV) or rigid cervical orthosis (CO). Our previous study suggested increased morbidity and mortality with the use of HV in the treatment of elderly patients with cervical spine fractures. We review a series of odontoid fractures in elderly patients and evaluate for predictors for in-hospital morbidity and mortality.There were 78 patients65 years of age who sustained a type II or III odontoid fracture from January 1997 to June 2004 identified from the Rhode Island Hospital Trauma registry. Demographic, mechanism, injury pattern, treatment, and outcome data were recorded. Patients were analyzed according to treatment method.The mean age was 80.7 +/- 0.9 years. There were 50 type II, 17 type III, and 11 combined fractures. There were 38 (49%) patients treated with HV: 34 with halo alone, and 4 after OP; 40 (51%) patients were treated without HV: 27 with CO, and 13 with OP. There was no difference in injury severity or baseline medical condition between HV and non-HV patients. There were 24 (31%) patients who died during their hospital stay. Of the HV patients, 42% died compared with 20% in the non-HV group (p = 0.03). Major complications occurred in 66% of HV patients compared with 36% of non-HV patients (p = 0.003).Odontoid fractures are associated with significant morbidity and mortality in elderly patients. Outcomes after treatment with HV appear inferior to those achieved with CO or OP.

A phase I trial was conducted to determine the maximally tolerated dose of erlotinib with concurrent gemcitabine, paclitaxel, and radiation for patients with locally advanced pancreatic cancer and to gather preliminary data on maintenance erlotinib after chemoradiation.Patients received gemcitabine, 75 mg/m2, and paclitaxel, 40 mg/m, weekly for 6 weeks with 50.4 radiation to the primary tumor and draining lymph nodes with a 2- to 3-cm margin. Erlotinib was administered over 3-dose levels (50-100 mg/d) with chemoradiation then all patients received 150 mg/d maintenance until disease progression.Seventeen patients were assessable for toxicity; 13 with locally advanced disease and 4 who had undergone resection but had positive margins. At erlotinib dosagesor =75 mg/d with chemoradiation the dose-limiting toxicities were diarrhea, dehydration, rash, myelosuppression, and small bowel stricture. Maintenance erlotinib, 150 mg/d, was well tolerated. The median survival of the 13 patients with locally advanced disease was 14.0 months and 6 of 13 (46%) had a partial response.The maximum tolerated dose of erlotinib with gemcitabine, paclitaxel and concurrent radiation is 50 mg/d for patients with locally advanced pancreatic cancer. Full dose maintenance erlotinib is well tolerated. Promising preliminary activity and overall survival were demonstrated.

Background: Cervical spine fractures (CSFs) in elderly patients are increasingly common as the population ages. In many centers, halo vest immobilization (HVI) is the treatment of choice. Our anecdotal experience suggested that elderly patients treated with HVI have frequent bad outcomes. The purpose of this study was to compare the outcomes of elderly and younger CSF patients as related to treatment (HVI, surgery, or hard collar). Methods: Registry data from our Level I trauma center were reviewed to identify patients admitted with CSFs during an 80-month period. We excluded those with Glasgow Coma Scale (GCS) score of 3 at admission or death within 24 hours of admission. Patients were grouped as OLD (aged ≥ 66 years) or YNG (aged 18-65 years). Data were compared using X 2 and Student's t test, with p < 0.05 considered statistically significant. Results: One hundred twenty-nine OLD (aged 79.7 ± 0.7 years) and 289 YNG (aged 383 ± 0.8 years) patients met study criteria. Injury Severity Score was higher in YNG (18.9 ± 0.8 vs. 14.8 ± 1.0, p < 0.05), and GCS score was the same (OLD, 13.7 ± 0.2; YNG, 13.0 ± 0.2; p = 0.06) in both, but mortality was higher in OLD patients (21% vs. 5%, p < 0.05). OLD HVI patients had higher mortality than YNG HVI (40% vs. 2%). Among OLD patients, age, Injury Severity Score, GCS, and number of comorbidities were the same for each treatment subgroup. Despite this, mortality for the HVI subgroup was higher than either the surgery or collar subgroup. Of the OLD HVI patients that died, 14 died with pneumonia and 10 had a cardiac or respiratory arrest that preceded death. Conclusion: OLD patients with CSFs have higher mortality than YNG. HVI in OLD patients is associated with the worst outcomes, irrespective of injury severity, and should be considered a last resort. Further study is warranted to determine the optimal treatment for CSF in OLD patients.

The purpose of this study was to review our experience with interfacility transfers to identify problems that could be addressed in the development of a statewide trauma system.The fundamental tenet of a trauma system is to get the right patient to the right hospital at the right time. This hinges on well-defined prehospital destination criteria, interfacility transfer protocols, and education of caregivers. Patients arriving at local community hospitals (LOCs) benefit from stabilization and transfer to trauma centers (TCs) for definitive care. However, in the absence of a formalized trauma system, patients may not reach the TC in a timely fashion and may not be appropriately treated or stabilized at LOCs prior to transfer.Our facility is a level I TC and regional referral center for a compact geographic area without a formal trauma system. The Trauma Registry was queried for adult patients admitted to the trauma service between January 1, 2001 and March 30, 2003. Patients were divided into 2 groups: those received directly from the scene (DIR) and those transferred from another institution (TRAN). Medical records were reviewed to elucidate details of the early care. Data are presented as mean +/- SEM. Continuous data were compared using Student t test, and categorical data using chi2. Transfer times were analyzed by one-way ANOVA.A total of 3507 patients were analyzed. The TRAN group had a higher Injury Severity Score (ISS) (17.5 versus 11.0, P0.05), lower Glasgow Coma Score (GCS) (13.3 versus 14.1, P0.05), lower initial systolic blood pressure (SBP) (130 versus 140, P0.05), and higher mortality (10% versus 79%, P0.05) than the DIR group. The average time spent at the LOC was 162 +/- 8 minutes. The subgroup of patients with hypotension spent an average of 134 minutes at the LOC, often receiving numerous diagnostic tests despite unavailability of surgeons to provide definitive care. Severe head injury (GCS = 3) triggered more prompt transfer, but high ISS was underappreciated and did not result in a prompt transfer in all but the most severely injured group (ISS40). Some therapeutic interventions were initiated at the LOCs, but many were required at the TC. A total of 23 (8%) TRAN patients required critical interventions within 15 minutes of arrival; mortality in this group was 52%. Mortality among those requiring laparotomy after transfer was 33%.All but the most severely injured patients spend prolonged periods of time in LOCs, and many require critical interventions upon arrival at the TC. It is unreasonable to expect immediate availability of surgeons or operating rooms in LOCs. Thus, trauma system planning efforts should focus on 1) prehospital destination protocols that allow direct transport to the TC; and 2) education of caregivers in LOCs to enhance intervention skill sets and expedite transfer to definitive care.

Background My colleagues and I compared trauma patient demographics and outcomes between two time periods in the last 10 years in our Level I trauma center to evaluate the impact of the marked evolution in trauma care and determine additional opportunities for improvement. Methods Our trauma registry was queried for adult trauma patients admitted from 1991 to 1993 (EARLY) and 1999 to 2001 (LATE). The EARLY period predated creation and maturation of a dedicated trauma service and Level I trauma center verification. Continuous data were compared using Student's t-test, and categorical data using chi-square. Results Increased transfers of severely injured patients from regional hospitals, combined with fewer admissions for "observation," resulted in fewer, but sicker, patients admitted in the LATE period. Patients were considerably older in the LATE period and mortality was higher. Despite higher acuity of patients, hospital and ICU lengths of stay were shorter in the LATE period. Nonoperative management of solid organ injuries was more common in the LATE period, but the overall operative volume was similar. Nonsurvivors in the LATE period had higher Injury Severity Scores and were older compared with the EARLY period. Mortality attributable to blunt CNS injury was higher, and that attributed to late sepsis and multiple organ failure was lower in the LATE period. Conclusions Over the past decade, more older, severely injured patients have been admitted to our Level I trauma center. Overall mortality among these higher acuity patients has increased, with a marked shift in attributable mortality to CNS injury and away from late sepsis and multiple organ failure. This highlights the need for continued efforts to identify optimal management strategies for severe brain injury. Additional areas for improvement include enhancement of our regional trauma network and injury prevention initiatives.

PURPOSE: To conduct a phase I study incorporating trastuzumab with paclitaxel, cisplatin, and radiation for adenocarcinoma of the esophagus. METHODS AND MATERIALS: Patients with adenocarcinoma of the esophagus without distant organ metastases were eligible. All patients received cisplatin 25 mg/m2 and paclitaxel 50 mg/m2 weekly for 6 weeks with radiation 50.4 Gy. HER-2/neu-positive patients (2+/3+ by immunohistochemistry) received weekly trastuzumab at dose levels of 1, 1.5, or 2 mg/kg weekly for 5 weeks after an initial bolus of 2, 3, or 4 mg/kg, respectively. HER-2/neu-negative patients received the same chemoradiation without trastuzumab as a control for toxicity. Dose-limiting toxicities were defined as grade 3 esophageal, cardiac, or pulmonary toxicity. RESULTS: Twelve of 36 screened patients (33%) overexpressed HER-2/neu by immunohistochemistry (seven 3+ and five 2+). Eight of 12 patients with HER-2/neu overexpression by IHC had an increase in the number of HER-2/neu genes, six from amplification of the HER-2/ neu gene and two were hypderdiploid for chromosome 17. Thirty patients were enrolled (12 HER-2/neu-positive and 18 HER-2/neu-negative controls). No increase in toxicity was seen with the addition of trastuzumab. One of 12 patients in the trastuzumab arm and 8 of 17 in the control arm had grade 3 esophagitis (p < or = .026). Mean left ventricular ejection fraction for the trastuzumab group was 57% before treatment and 56% after treatment. CONCLUSION: HER-2/neu is overexpressed in approximately one-third of esophageal adenocarcinomas. Trastuzumab can be added at full dose to cisplatin, paclitaxel, and radiation. Future studies of trastuzumab in esophageal adenocarcinoma are indicated.

Background: Emerging evidence suggests that, contrary to standard teaching, isolated brain injury may be associated with hypotension. This study sought to determine the frequency of isolated brain injury-induced hypotension in blunt trauma victims. Methods: Hypotensive adult trauma patients were categorized according to the cause of hypotension: hemorrhagic (hemoglobin < 11.0), neurogenic, isolated brain, or other. Their clinical data and outcomes were compared. Results: The cause of hypotension was hemorrhagic in 113 (49%), isolated brain injury in 30 (13%), neurogenic in 14 (6%), and other causes in 24 (10%). Fifty (22%) were indeterminate. Hemorrhagic, isolated brain, and neurogenic groups were similar in age, Injury Severity Score, and systolic blood pressure. The Glasgow Coma Scale score of the isolated brain group was lower than in the hemorrhagic group (4.4 vs. 8.4, p < 0.05). Mortality was higher in the isolated brain group compared with the hemorrhagic group (80% vs. 50%, p < 0.05) and in the subgroup of hemorrhagic patients with versus without associated brain injury (57% vs. 39%,p < 0.05). Conclusion: Isolated brain injuries account for 13% of hypotensive events after blunt trauma and are associated with an increased mortality compared with hemorrhage-induced hypotension. In hypotensive brain-injured patients, hemorrhagic sources should be excluded rapidly, and the focus should be on resuscitation.

Background: Missed injuries (MIs) adversely affect patient outcome and damage physician/institutional credibility. The primary and secondary surveys are designed to identify all of a patient's injuries and prioritize their management; however, MIs are prevalent in severely injured and multisystem trauma patients, especially when the patient's condition precludes completion of the secondary survey. We hypothesized that implementation of a routine tertiary trauma survey (TS) would reduce the incidence of MIs in a Level I trauma center. Methods: In mid 1999, a TS form was created and TS documentation was mandated on all trauma intensive care unit (TICU) patients within 24 hours of admission. Patient data, including TS documentation and injury patterns, were concurrently recorded in an institutional trauma registry. Data were compared for patients admitted in 1997 to 1998 (PRE period) and 2000 to 2001 (POST period) using X 2 or Student's t test. Results: MIs decreased from 2.4% to 1.5% overall, and from 5.7% to 3.4% in TICU patients, after TS implementation. Patients with MIs were slightly older (49 vs. 45 years; p > 0.05) and had higher Injury Severity Scores (21 vs. 10; p < 0.05) than patients without MIs. Sixty percent of MI patients had brain injuries, 56% were admitted to the TICU, and 26% went directly from the emergency department to the operating room. The large majority of MIs in the POST period were detected in patients not undergoing timely TS. Conclusion: ICU patients-particularly brain injury victims and those undergoing emergent surgical procedures-appear to be at highest risk for MI. Implementation of a standardized TS decreased MIs by 36% in our Level I trauma center, and more timely TS would likely have further reduced MIs. A TS should be routine in trauma centers.

Purpose: To determine the maximum tolerated dose (MTD) and dose-limiting toxicities of gemcitabine, paclitaxel, and concurrent radiation for pancreatic cancer. Methods and Materials: Twenty patients with locally unresectable pancreatic cancer were studied. The initial dose level was gemcitabine 75 mg/m 2 and paclitaxel 40 mg/m 2 weekly for 6 weeks. Concurrent radiation to 50.4 Gy was delivered in 1.8 Gy fractions. The radiation fields included the primary tumor, plus the regional peripancreatic, celiac, and porta hepatis lymph nodes. Results: Dose-limiting toxicities of diarrhea, dehydration, nausea, and anorexia occurred in 3 of 3 patients at the second dose level of gemcitabine, 150 mg/m 2 /week. An intermediate dose level of gemcitabine, 110 mg/m 2 /week, was added, but gastrointestinal toxicity and pulmonary pneumonitis were encountered. The MTD therefore was gemcitabine 75 mg/m 2 /week with paclitaxel 40 mg/m 2 /week and concurrent radiation. Two of 11 patients treated at the MTD had Grade 3/4 toxicity. Four of 10 assessable patients treated at the MTD responded (40%), including one pathologic complete response. Conclusion: The maximum tolerated dosage of gemcitabine is 75 mg/m 2 /week with paclitaxel 40 mg/m 2 /week and conventional 50.4 Gy radiation fields. A Phase II Radiation Therapy Oncology Group study is under way.

A well-described array of metabolic derangements occurs after severe trauma or burn. This response includes hyperdynamic circulation, fever due to resetting of the hypothalamic temperature set point, immune deficiency, impaired wound healing, peripheral insulin resistance, alteration of hepatic protein synthesis, skeletal muscular protein catabolism, and elevated systemic energy expenditure. 1–9 During the flow phase after injury, survivors manifest a hyperdynamic circulation and begin to overtly display other systemic manifestations of global hypermetabolism. 10 Defects of both cellular and humoral immune function increase the likelihood of infection, hepatic protein synthesis shifts from storage and housekeeping proteins to acute phase response proteins, peripheral tissue insulin resistance with hyperglycemia occurs, and catabolism of proteins stores (predominantly skeletal muscle) leads to erosion of lean body mass. Fluxes of substrate fuels are altered with glucose, fat, and amino acids being supplied to the wound from hepatic gluconeogenesis, lipolysis, and auto-catabolized muscle protein. With the exception of circulatory physiologic parameters, these diverse systemic alterations are difficult to quantify. Associated with the hypermetabolic response is elevation in systemic energy expenditure. 11 This has been shown to correlate with the degree of muscle protein catabolism, impaired wound healing, and immune deficiency. 12-14 Resting energy expenditure as a correlate to total energy expenditure can be measured relatively easily at the bedside utilizing indirect calorimetry. Resting energy expenditure is determined from inspired and expired gases, measuring oxygen consumption and carbon dioxide production. It is noninvasive, reproducible, and immediately quantifiable (results are usually obtained within minutes). The general correlation between elevated energy expenditure and muscle catabolism has led to the notion that energy expenditure determines energy demand, which is required to offset catabolism. These demands, then, are met through the dietary delivery of calories. We hypothesize that muscle catabolism proceeds after severe burn regardless of caloric balance (caloric administration –measured energy expenditure). The goal of this study was twofold. First, we sought to determine the clinical relevance of elevated energy expenditure after burn, specifically whether elevated energy expenditure correlated with increased morbidity or mortality in the setting of severe burn. Second, we sought to determine whether energy expenditure could be used to define caloric demand to optimize attenuation of erosion of lean body mass. Our hypotheses were that 1) systemic energy expenditure is reflective of the degree of illness increasing to a point of exhaustion, after which decreases would correlate with mortality; and that 2) no optimal energy/caloric balance exists that abolishes catabolism of lean mass when at least 1.2 times the measured resting energy expenditure is delivered.

Background Current literature is controversial regarding the importance of obese BMI classifications as a risk factor for pulmonary complications after outpatient surgery. The objective of the current investigation was to evaluate predictors of pulmonary outcomes after outpatient surgery and to assess the importance of BMI weight classifications in risk assessment. Study Design Patients with "outpatient" recorded as their inpatient/outpatient status in the 2012 to 2013 NSQIP database were included. The primary outcome of interest was the occurrence of a new pulmonary complication (eg pneumonia, pulmonary embolism, unplanned intubation, or ventilator-assisted respiration for greater than 48 hours) within 30 days of surgery. Results There were 444,532 cases included in the final analysis. There were 996 (0.22%; 99% CI 0.21% to 0.24%) all-cause pulmonary complications. Binary logistic regression identified BMI as an independent predictor of a pulmonary complication, unadjusted odds ratio 1.091 (99.75% CI 1.026 to 1.160) per 5 kg/m 2 change in BMI, p 2 was 1.44 (99.75% CI 1.01 to 2.06; p = 0.002) and with a BMI of 40 to 49.99 kg/m 2 was 1.68 (99.75% CI 1.13 to 2.50; p 2 . Conclusions Obese classes II and III were associated with an independent risk of a pulmonary complication. The risk associated with obesity was low compared with the risk associated with advanced age, prolonged surgical duration, and the risk of comorbidities including congestive heart failure, COPD, and renal failure.

Optimal surgical decision-making and informed consent for palliative procedures is limited by a lack of appropriate outcomes data. Elevated C-reactive protein (CRP) may help guide patient selection for palliative surgery.Procedures to palliate symptoms of advanced cancer were identified from a prospective palliative surgery database. Patients with a recorded preoperative serum CRP were identified and observed for at least 180 days or until death.Fifty patients were identified who underwent an elective palliative procedure from July 2006 to June 2012. Presenting symptoms included gastrointestinal obstruction (40%), tumor-related pain (38%) or bleeding (12%), and other (10%). Symptom improvement was documented for 37 patients (74%). Palliative procedures were associated with 30-day postoperative morbidity (42%) and mortality (10%). CRP (range 1-144 mg/L, median 9.7 mg/L) was elevated in 27 patients (54%) and was independently associated with developing a major complication (P = 0.005) and decreased overall survival (166 vs. 659 days, P 0.0001).Patients with advanced cancer can be afforded symptom improvement and the opportunity for improved quality of life following palliative procedures. Elevated preoperative CRP may help identify patients who are less likely to realize the benefits of palliative operations.

Purpose: To determine the activity and toxicity of paclitaxel and concurrent radiation for pancreatic cancer. Methods and Materials: Forty-four patients with locally unresectable pancreatic cancer were studied. Patients received paclitaxel, 50 mg/m 2 by 3 h i.v. (IV) infusion, weekly, on Days 1, 8, 15, 22 and 29. Radiation was administered concurrently to a total dose of 50.4 Gy, in 1.80 Gy fractions, for 28 treatments. Results: Nausea and vomiting were the most common toxicities, Grade 3 in five patients (12%). Two patients (5%) had Grade 4 hypersensitivity reactions to their first dose of paclitaxel. Of 42 evaluable patients, the overall response rate was 26%. The median survival was 8 months, and the 1-year survival was 30%. Conclusion: Concurrent paclitaxel and radiation demonstrate local-regional activity in pancreatic cancer. Future investigations combining paclitaxel with other local-regional and systemic treatments are warranted.

More than 30 years ago, the clinical presentation of acute respiratory distress syndrome was reported by Ashbaugh et al 1 from a series of patients with the acute onset of tachypnea, hypoxemia, decreased pulmonary compliance, and diffuse bilateral infiltrates on a chest radiograph. Four years later, this clinical consortium of signs and symptoms was officially termed adult respiratory distress syndrome (ARDS). 2 Despite advances in critical care, death rates have remained high (>50%), 3–6 with recent reports suggesting only a small improvement in outcome. 7–9 The risk factors associated with the development of ARDS are sepsis, trauma, multiple transfusions, aspiration of gastric contents, pulmonary contusion, pneumonia, and near-drowning. 10 The current definition of ARDS has evolved from the five initial diagnostic criteria: acute respiratory failure from a known risk diagnosis, low respiratory compliance, a pulmonary artery occlusion pressure of 16 mmHg or less, diffuse bilateral infiltrates on a chest radiograph, and a decreased arterial-to-alveolar partial pressure of oxygen ratio (

"What's New in Surgery" evolves from the contributions of leaders in each of the fields of surgery. In every instance the author has been designated by the appropriate Council from the American College of Surgeons' Advisory Councils for the Surgical Specialties. This feature will be presented in issues of the Journal through the year beginning in 2001 (formerly published in one issue, February, of each volume of JACS) .

Objective To compare the effect on clinical outcome of changing a surgical intensive care unit from an open to a closed unit. Design The study was carried out at a surgical intensive care unit in a large tertiary care hospital, which was changed on January 1, 1996, from an open unit, where private attending physicians contributed and controlled the care of their patients, to a closed unit, where patients' medical care was provided only by the surgical critical care team (ABS or ABA board-certified intensivists). A retrospective review was undertaken over 6 consecutive months in each system, encompassing 274 patients (125 in the open-unit period, 149 in the closed-unit period). Morbidity and mortality were compared between the two periods, along with length-of-stay (LOS) and number of consults obtained. A set of independent variables was also evaluated, including age, gender, APACHE III scores, the presence of preexisting medical conditions, the use of invasive monitoring (Swan-Ganz catheters, central and arterial lines), and the use of antibiotics, low-dose dopamine (LDD) for renal protection, vasopressors, TPN, and enteral feeding. Results Mortality (14.4% vs. 6.04%, p = 0.012) and the overall complication rate (55.84% vs. 44.14%, p = 0.002) were higher in the open-unit group versus the closed-unit group, respectively. The number of consults obtained was decreased (0.6 vs. 0.4 per patient, p = 0.036), and the rate of occurrence of renal failure was higher in the open-unit group (12.8% vs. 2.67%, p = 0.001). The mean age of the patients was similar in both groups (66.48 years vs. 66.40, p = 0.96). APACHE III scores were slightly higher in the open-unit group but did not reach statistical significance (39.02 vs. 36.16, p = 0.222). There were more men in the first group (63.2% vs. 51.3%). The use of Swan-Ganz catheters or central and arterial lines were identical, as was the use of antibiotics, TPN, and enteral feedings. The use of LDD was higher in the first group, but the LOS was identical. Conclusions Conversion of a tertiary care surgical intensive care unit from an open to closed environment reduced dopamine usage and overall complication and mortality rates. These results support the concept that, when possible, patients in surgical intensive care units should be managed by board-certified intensivists in a closed environment.

Background: Recent studies have questioned the use of aggressive fluid resuscitation after uncontrolled arterial hemorrhage until the bleeding is controlled. However, it remains unknown whether resuscitation after hemorrhage from a venous origin (usually nonaccessible to surgical intervention) has any beneficial or deleterious effects on regional perfusion. The aim of this study, therefore, was to determine whether increased volume of fluid resuscitation after uncontrolled venous hemorrhage improves hemodynamic profile and regional perfusion in various tissues. Materials and Methods: After methoxyflurane anesthesia and midline laparotomy, both lumbar veins in the rat were severed, which resulted in lowering the mean arterial blood pressure to approximately 40 mm Hg. This pressure was maintained for 45 minutes by allowing further bleeding from the lumbar veins. The abdominal incision was then closed in layers and the animals received either 0, 10, or 30 mL of lactated Ringer's solution intravenously over a period of 60 minutes. Cardiac output and regional blood flow were determined by radioactive microspheres immediately or at 1.5 hours after the completion of resuscitation. Results: Fluid resuscitation with 10 or 30 mL lactated Ringer's solution increased mean arterial blood pressure and cardiac output immediately after resuscitation compared with the nonresuscitated animals. At both time points, regional perfusion in the heart, kidney and intestines remained significantly decreased compared with the sham values, irrespective of the volume of fluid resuscitation. Moreover, no further improvements in hemodynamics or regional perfusion occurred when volume resuscitation was increased from 10 mL to 30 mL. Total hepatic blood flow, however, increased with 10 mL lactated Ringer's solution compared with the other hemorrhage groups and the increase was evident even at 1.5 hours after resuscitation. Conclusions: Fluid resuscitation after uncontrolled venous bleeding transiently increased cardiac output and mean arterial blood pressure compared with nonresuscitated animals. Moderate fluid administration, i.e., 10 mL, however, did increase total hepatic blood flow. In contrast, increasing the resuscitation volume to 30 mL did not improve hemodynamic parameters or regional perfusion. Thus moderate instead of no resuscitation or larger volume of resuscitation is recommended in an uncontrolled model of venous hemorrhage.

Treatment protocols for the management of burned hands are essential for integrating team efforts and achieving optimal functional results. Standard protocols are especially useful during mass casualty incidents, when the admission of multiple patients with large burns and/or associated injuries may reduce the priority usually accorded the hands. We prospectively evaluated a surgical and rehabilitative treatment protocol for burned hands during a mass casualty incident, after which 43 burn patients with 82 burned hands were admitted to one burn center. Soft-tissue management was individualized to achieve, if possible, wound closure within 14 days, and included the use of topical antimicrobials, cutaneous debridement and/or tangential excision, biologic dressings, and split-thickness autografts. Range of motion therapy was based on daily measurement of active motion of the metacarpophalangealjoints. Static splinting alternating with continuous passive motion every 4 hours was utilized for sedated patients. Continuous passive motion alternating with active ranging and night splinting was utilized for metacarpophalangeal flexion70 degrees. Active ranging and progressive resistance was utilized for metacarpophalangeal flexionor =70 degrees. Sixty-four hands required excision and grafting, with 89 percent having at least one autografting procedure completed by postburn day 16. Total active motion of the hands treated averaged 220.6 degrees on discharge and 229.9 degrees at 3 months after injury. Mean hand grip strength was 60.8 pounds at discharge and 66.0 pounds at 3 months after injury. Adherence to a standard hand burn protocol resulted in timely wound coverage and recovery of hand function for a large group of patients treated at a single burn facility after a mass casualty incident.

Pressure-controlled ventilation is used to treat smoke inhalation injury to achieve adequate oxygenation and ventilation at lower peak inspiratory pressures. A portable pressure-controlled time-cycled transport ventilator permits this modality to be used in the field. We have examined the safety and efficacy of this ventilator for aeromedical transfer of thermally injured patients. Burn flight teams transported 146 intubated patients with thermal injury to the U.S. Army Burn Center with this system. The average extent of burn injury was 40.45% total body surface area with an average full-thickness injury of 25.29% total body surface area. The transport ventilator was used for 57 rotary wing and 89 fixed wing missions. The study group was transported a total of 86,889 miles without in-flight morbidity, mortality, or failure of ventilation. Arterial blood gas analysis at conclusion of flight demonstrated an arterial pHor = 7.35 in 85% of the patients, an arterial partial pressure of carbon dioxideor = 45 torr in 97%, and an arterial partial pressure of oxygenor = 70 torr in 99%. Pressure-controlled ventilation performed by an experienced transport team with this ventilator is safe and effective for the long-range aeromedical transfer of intubated patients with burns.

Background General surgery residency training has changed with adoption of the 80-hour work week, patient expectations, and the malpractice environment, resulting in decreased resident autonomy during the chief resident year. There is considerable concern that graduating residents are not prepared for independent surgical practice. Study Design Two online surveys were developed, one for "young surgeons" (American College of Surgeons [ACS] Fellows 45 years of age and younger) and one for "older surgeons" (ACS Fellows older than 45 years of age). The surveys were distributed by email to 2,939 young and 9,800 older surgeons. The last question was open-ended with a request to provide comments. A qualitative and quantitative analysis of all comments was performed. Results The response rate was 9.6% (282 of 2,939) of young and 10% (978 of 9,800) of older surgeons. The majority of young surgeons (94% [58.7% strongly agree, 34.9% agree]) stated they had adequate surgical training and were prepared for transition to the surgery attending role (91% [49.6% strongly agree, 41.1% agree]). In contrast, considerably fewer older surgeons believed that there was adequate surgical training (59% [18.7% strongly agree, 40.2% agree]) or adequate preparation for transition to the surgery attending role (53% [16.93% strongly agree, 36.13% agree]). The 2 groups' responses were significantly different, chi-square test of association (3) = 15.73, p = 0.0012. Older surgeons focused considerably more on residency issues (60% vs 42%, respectively), and young surgeons focused considerably more on business and practice issues (30% vs 14%, respectively). Conclusions Young and older surgeons' perceptions of general surgery residents' readiness to practice independently after completion of general surgery residency differ significantly. Future work should focus on determination of specific efforts to improve the transition to independent surgery practice for the general surgery resident.

Importance In 2010, the Accreditation Council for Graduate Medical Education (ACGME) proposed increased regulation of work hours and supervision for residents. New Common Program requirements that took effect in July 2011 dramatically changed the customary 24-hour in-house call schedule. Surgical residents are more likely to be affected by these duty hour restrictions. Objective To examine surgical residents' views of the 2011 ACGME Common Program requirements after implementation in July 2011. Design A 20-question electronic survey was administered 6 months after implementation of 2011 ACGME regulations to 123 participating institutions. Setting ACGME-accredited teaching hospitals in the United States and US territories. Participants The total sample was 1013 voluntarily participating residents in general surgery and surgical specialties at ACGME-accredited institutions. Main Outcomes and Measures Residents' perceptions of changes in education, patient care, and quality of life after institution of 2011 ACGME duty hour regulations and their compliance with these rules. Results A subset of 1013 residents training in general surgery or a surgical subspecialty was identified from a demographically representative sample of 6202 survey respondents. Most surgical residents indicated that education (55.1%), preparation for senior roles (68.4%), and work schedules (50.7%) are worse after implementation of the 2011 regulations. They reported no change in supervision (80.8%), safety of patient care (53.4%), or amount of rest (57.8%). Although quality of life is perceived as better for interns (61.9%), most residents believe that it is worse for senior residents (54.4%). A majority report increased handoffs (78.2%) and a shift of junior-level responsibilities to senior residents (68.7%). Finally, many residents report noncompliance (67.6%) and duty hour falsification (62.1%). Conclusions and Relevance A majority of surgical residents disapprove of 2011 ACGME Common Program requirements (65.9%). The proposed benefits of the increased duty hour restrictions—improved education, patient care, and quality of life—have ostensibly not borne out in surgical training. It may be difficult for residents, particularly in surgical fields, to learn and care for patients under the 2011 ACGME regulations.
