Gender differences in academic surgery, work-life balance, and satisfaction.

BACKGROUND: An increasing number of women are pursuing a career in surgery. Concurrently, the percentage of surgeons in dual-profession partnerships is increasing. We sought to evaluate the gender differences in professional advancement, work-life balance, and satisfaction at a large academic center. MATERIALS AND METHODS: All surgical trainees and faculty at a single academic medical center were surveyed. Collected variables included gender, academic rank, marital status, family size, division of household responsibilities, and career satisfaction. Student t-test, Fisher's exact test, and chi-square test were used to compare results. RESULTS: There were 127 faculty and 116 trainee respondents (>80% response rate). Respondents were mostly male (77% of faculty, 58% of trainees). Women were more likely than men to be married to a professional (90% versus 37%, for faculty; 82% versus 41% for trainees, P < 0.001 for both) who was working full time (P < 0.001) and were less likely to be on tenure track (P = 0.002). Women faculty were more likely to be primarily responsible for childcare planning (P < 0.001), meal planning (P < 0.001), grocery shopping (P < 0.001), and vacation planning (P = 0.003). Gender-neutral responsibilities included financial planning (P = 0.04) and monthly bill payment (P = 0.03). Gender differences in division of household responsibilities were similar in surgical trainees except for childcare planning, which was a shared responsibility. CONCLUSIONS: Women surgeons are more likely to be partnered with a full-time working spouse and to be primarily responsible for managing their households. Additional consideration for improvement in recruitment and retention strategies for surgeons might address barriers to equalizing these gender disparities.

Infectious complications in obese patients after trauma.

BACKGROUND: Obesity is a public health concern in the United States due to its increasing prevalence, especially in younger age groups. Trauma is the most common cause of death for people under aged 40 y. The purpose of this study is to determine the association between obesity and specific infectious complications after traumatic injury. MATERIALS AND METHODS: A retrospective analysis was conducted using data from the 2012 National Trauma Data Bank. The National Trauma Data Bank defined obesity as having a body mass index of 30 or greater. Descriptive statistics were calculated and stratified by obesity status. A hierarchical regression model was used to determine the odds of experiencing an infectious complication in patients with obesity while controlling for age, gender, diabetes, number of comorbidities, injury severity, injury mechanism, head injury, and surgical procedure. RESULTS: Patients with a body mass index of 30 or greater compared with nonobese patients had increased odds of having an infectious complication (Odds Ratio, 1.59; 1.49-1.69). In addition to obesity, injury severity score greater than 29, age 40 y or older, diabetes, comorbid conditions, and having a surgical procedure were also predictive of an infectious complication. CONCLUSIONS: Our results indicate that trauma patients with obesity are nearly 60% more likely to develop an infectious complication in the hospital. Infection prevention and control measures should be implemented soon after hospital arrival for patients with obesity, particularly those with operative trauma.

Optimizing transfusion strategies in damage control resuscitation: current insights.

From clinical and laboratory studies of specific coagulation defects induced by injury, damage control resuscitation (DCR) emerged as the most effective management strategy for hemorrhagic shock. DCR of the trauma patient who has sustained massive blood loss consists of 1) hemorrhage control; 2) permissive hypotension; and 3) the prevention and correction of trauma-induced coagulopathies, referred to collectively here as acute coagulopathy of trauma (ACOT). Trauma patients with ACOT have higher transfusion requirements, may eventually require massive transfusion, and are at higher risk of exsanguinating. Distinct impairments in the hemostatic system associated with trauma include acquired quantitative and qualitative platelet defects, hypocoagulable and hypercoagulable states, and dysregulation of the fibrinolytic system giving rise to hyperfibrinolysis or a phenomenon referred to as fibrinolytic shutdown. Furthermore, ACOT is a component of a systemic host defense dysregulation syndrome that bears several phenotypic features comparable with other acute systemic physiological insults such as sepsis, myocardial infarction, and postcardiac arrest syndrome. Progress in the science of resuscitation has been continuing at an accelerated rate, and clinicians who manage catastrophic blood loss may be incompletely informed of important advances that pertain to DCR. Therefore, we review recent findings that further characterize the pathophysiology of ACOT and describe the application of this new information to optimization of resuscitation strategies for the patient in hemorrhagic shock.

Prevalence of cardiovascular and respiratory complications following trauma in patients with obesity.

BACKGROUND: It is generally accepted that obesity puts patients at an increased risk for cardiovascular and respiratory complications after surgical procedures. However, in the setting of trauma, there have been mixed findings in regards to whether obesity increases the risk for additional complications. OBJECTIVE: The aim of this study was to identify whether obese patients suffer an increased risk of cardiac and respiratory complications following traumatic injury. METHODS: A retrospective analysis of 275,393 patients was conducted using the 2012 National Trauma Data Bank. Hierarchical regression modeling was performed to determine the probability of experiencing a cardiac or respiratory complication. RESULTS: Patients with obesity were at a significantly higher risk of cardiac and respiratory complications compared to patients without obesity [OR: 1.81; CI: 1.72-1.91]. Prevalence of cardiovascular and respiratory complications for patients with obesity was 12.6% compared to 5.2% for non-obese patients. CONCLUSIONS: Obesity is predictive of an increased risk for cardiovascular and respiratory complications following trauma.

Trends in Emergency Department Visits for Nonfatal Violence-Related Injuries Among Adolescents in the United States, 2009-2013.

PURPOSE: Violence-related injuries are a major cause of death and disability among adolescents in the United States. The objective of this study was to examine trends in adolescent violence-related injuries between 2009 and 2013. METHODS: This study examined data from the National Electronic Injury Surveillance System-All Injury Program for years 2009-2013. Linear regression was used to assess trends in rates of violence-related injuries among adolescents aged between 10 and 19 years. RESULTS: We found overall rates of nonfatal violence-related injuries among all adolescents did not change significantly across the study years (p = .502). However, self-harm injury rates have significantly increased among female and younger adolescents during the period (p = .001 and .011, respectively). CONCLUSIONS: Our results indicate that the overall intentional injury rates in adolescents have been stable; however, rates of self-injury have significantly increased in younger adolescents and females. Future research should focus on exploring causes of increases in self-harm injuries in these subpopulations.

Understanding the Barriers to Hiring and Promoting Women in Surgical Subspecialties.

BACKGROUND: The objective of this study was to characterize potential disparities in academic output, NIH-funding, and academic rank between male and female surgical faculty and identify subspecialties in which these differences may be more pronounced. STUDY DESIGN: Eighty metrics for 4,015 faculty members at the top-55 NIH-funded departments of surgery were collected. Demographic characteristics, NIH funding details, and scholarly output were analyzed. A new metric, academic velocity (V), reflecting recent citations is defined. RESULTS: Overall, 21.5% of surgical faculty are women. The percentage of female faculty is highest in science/research (41%) and surgical oncology (34%), and lowest in cardiothoracic surgery (9%). Female faculty are less likely to be full professors (22.7% vs 41.2%) and division chiefs (6.2% vs 13.6%). The fraction of women who are full professors is lowest in cardiothoracic surgery. Overall median numbers of publications/citations are lower for female faculty compared with male surgical faculty (21 of 364 vs 43 of 723, p < 0.001), and these differences are more pronounced for assistant professors. Current/previous NIH funding (21.3% vs 24%, p = NS) rates are similar between women and men, and surgical departments with more female full professors have higher NIH funding ranking (R(2) = 0.14, p < 0.05). In certain subspecialties, female associate and full professors outperform male counterparts. Overall, female authors have higher numbers of more recent citations. CONCLUSIONS: Subspecialty involvement and academic performance differences by sex vary greatly by subspecialty type and are most pronounced at the assistant professor level. Identification of potential barriers for entry of women into certain subspecialties, causes for the observed lower number of publications/citations among female assistant professors, and obstacles for attaining leadership roles need to be determined. We propose a new metric for assessment of publications/citations that can offset the effects of seniority differences between male and female faculty members.

Cardiac operations in patients with hematologic malignancies.

OBJECTIVES: Patients with hematologic malignancies are frequently in need of major cardiac operations. Previous reports suggest an increased risk for perioperative complications in these immunodeficient patients. METHODS: Patients diagnosed with any type of hematologic malignancy who underwent open-heart surgery at our institution between 7/1996 and 6/2002 were identified. Their hospital charts were reviewed; demographics, perioperative data and outcomes were recorded. RESULTS: There were 24 patients (20 men, 4 women); mean age was 68+/-13 years (range 31-84 years). Ten patients had chronic lymphocytic leukemia, seven non-Hodgkin lymphomas, three multiple myeloma and one Hodgkin's disease, chronic myelocytic leukemia, hairy cell leukemia and cutaneous T-cell lymphoma each. The mean pre-operative duration of the hematologic disease was 6.6 years. Twenty-two patients underwent coronary artery bypass grafting (with valve replacement in three patients) and two patients had isolated valve replacement. There was one in-hospital death (4.1%). Twelve patients (50%) had a minor or major complication. Seven reoperations were required-five during the same admission (one for mediastinal bleeding, one for an expanding femoral pseudoaneurysm, one for acute cholecystitis and two for IACD/pacer insertion) and two within 30 days (one for deep sternal wound infection and one for leg wound infection). Mean post-operative stay was 8.2+/-5.8 days and mean ICU stay was 1.6+/-1.1 days. There were three late deaths-two were due to progression of the hematologic disease. The 3-year actuarial survival was 83%. CONCLUSIONS: Cardiac operations can be performed with acceptable mortality but significant morbidity rates in patients with hematologic malignancies. Bleeding and infectious complications are most frequently seen and usually lead to reoperations. These findings warrant caution during patient selection.

Unplanned intubation: when and why does this deadly complication occur?

BACKGROUND: Risk factors for unplanned intubation have been delineated, but details regarding when and why reintubations occur as well as strategies for prevention have not been defined. METHODS: Over a 2-year period, 104 of 3,141 patients (3.3%) monitored via the American College of Surgeons-National Surgical Quality Improvement Program required unplanned intubation. These patients were compared to those who remained extubated and were characterized by (1) the operation performed; (2) the postoperative day when reintubation occurred; and (3) the underlying causes. RESULTS: Patients who required reintubation were significantly older (65.8 years) and were more likely to be male (55%) and to have several comorbidities, weight loss (16%), dependency (14%), or sepsis (9%). The operations complicated most commonly by unplanned intubation were gastrectomy (13%), nephrectomy (10%), colectomy (9%), pancreatectomy (8%), hepatectomy (7%), and enterectomy (6%). The most common causes and median postoperative days were sepsis (33%, day 8) and aspiration/pneumonia (31%, day 4). Sepsis was due most commonly to an abdominal or pelvic abscess (74%), which was frequently not recognized despite an inflammatory response. Aspiration occurred most commonly after upper abdominal operations (78%) despite signs of diminished bowel function. CONCLUSION: Postoperative sepsis and aspiration/pneumonia account for two thirds of unplanned intubations. Opportunities for management of patients exist for the prevention of this deadly complication.

Hemodynamic monitoring in the intensive care unit.

Patients in the intensive care unit are often critically ill with inadequate tissue perfusion and oxygenation. This inadequate delivery of substrates at the cellular level is a common definition of shock. Hemodynamic monitoring is the observation of cardiovascular physiology. The purpose of hemodynamic monitoring is to identify abnormal physiology and intervene before complications, including organ failure and death, occur. The most common types of invasive hemodynamic monitors are central venous catheters, pulmonary artery catheters, and arterial pulse-wave analysis. Ultrasonography is a noninvasive alternative being used in intensive care units for hemodynamic measurements and assessments.
