Has the Increase of Women in Surgical Training Programs Led to a Concomitant Increase in Female Leadership Positions? A 10-Year Analysis.

INTRODUCTION: Women represent greater than 50% of medical students in America and are becoming increasingly well represented in surgical fields. However, parity at the trainee level has yet to be accomplished, and surgical leadership positions have remained disproportionately biased toward men. To date, there have been no comparisons on the progress within plastic surgery and other surgical specialties. This investigates the gender disparity in resident and leadership representation over the past 10 years within surgical specialties and how these disparities compare to plastic surgery. METHODS: Counts of female and male residents and surgical society leaders were collected from 2008 to 2018. Surgical fields included plastic, vascular, urologic, neurologic, orthopedic, cardiothoracic, and general surgery. Leadership positions were defined as board seats on executive committees of major surgical societies or board associations. Data were acquired from publicly available sources or provided directly from the organizations. Resident data were obtained from the Accreditation Council of Graduate Medical Education residents' reports. Individuals holding more than 1 leadership position within a year were counted only once. RESULTS: In our aggregated analysis, the proportion of women in surgical leadership lags behind women in surgical residency training across all specialties (13.2% vs 27.3%, P < 0.01). General surgery had the highest proportion of female residents and leaders (35% and 18.8%, P < 0.01), followed by plastic (32.2% and 17.3%, P < 0.01), vascular (28.2% and 11.3%, P < 0.01), urologic (24.3% and 5.1%), and cardiothoracic surgery (20.5% and 7.8%, P < 0.01). Women in surgical leadership, however, increased at a faster rate than women in surgical training (11% vs 7%, P < 0.05). Plastic surgery showed the greatest rate of increase in both residents and leaders (17% and 19%, P < 0.05) followed by cardiothoracic surgery (16% and 9%, P < 0.05) and general surgery (8% and 14%, P < 0.05). For neurologic and orthopedic surgery, neither the difference in proportions between residents and leaders nor the yearly growth of these groups were significant. CONCLUSIONS: Between 2008 and 2018, women in plastic surgery training and leadership positions have shown the most significant growth compared with other surgical subspecialties, demonstrating a strong concerted effort toward gender equality among surgical professions.

Health-related quality of life impacts upon 5-year survival after coronary artery bypass surgery.

BACKGROUND: Poor preoperative health-related quality of life (HRQoL) has been associated with reduced short-term survival after coronary artery bypass graft (CABG) surgery; however, its impact on long-term mortality is unknown. This study's objective was to determine if baseline HRQoL status predicts 5-year post-CABG mortality. METHODS: This prespecified, randomized on/off bypass follow-up study (ROOBY-FS) subanalysis compared baseline patient characteristics and HRQoL scores, obtained from the Seattle Angina Questionnaire (SAQ) and Veterans RAND Short Form-36 (VR-36), between 5-year post-CABG survivors and nonsurvivors. Standardized subscores were calculated for each questionnaire. Multivariable logistic regression assessed whether HRQoL survey subcomponents independently predicted 5-year mortality (p ≤ .05). RESULTS: Of the 2203 ROOBY-FS enrollees, 2104 (95.5%) completed baseline surveys. Significant differences between 5-year post-CABG deaths (n = 286) and survivors (n = 1818) included age, history of chronic obstructive pulmonary disease, stroke, peripheral vascular disease, renal dysfunction, diabetes, lower left ventricular ejection fraction, atrial fibrillation, depression, non-White race/ethnicity, lower education status, and off-pump CABG. Adjusting for these factors, baseline VR-36 physical component summary score (p = .01), VR-36 mental component summary score (p < .001), and SAQ physical limitation score (p = .003) were all associated with 5-year all-cause mortality. CONCLUSIONS: Pre-CABG HRQoL scores may provide clinically relevant prognostic information beyond traditional risk models and prove useful for patient-provider shared decision-making and enhancing pre-CABG informed consent.

Risk Factors Associated With Postmastectomy Breast Cancer Lymphedema: A Multicenter Retrospective Analysis.

BACKGROUND: Lymphedema is an edematous condition that afflicts the postmastectomy breast cancer population, with diminished quality of life with substantial financial costs. The factors predictive of postmastectomy lymphedema development in breast cancer patients are unknown. The objective was to evaluate the trends over time in lymphedema development and the risk factors predictive of lymphedema-related events within 2 years of mastectomy. METHODS: Using the New York Statewide Planning and Research Cooperative System multicenter deidentified database from 2010 to 2016, a total of 65,543 breast cancer postmastectomy female patients (mean age, 59 ± 20 years) were identified across 177 facilities. The breast cancer patients were followed for any 2-year postmastectomy lymphedema-related events. A multivariable model identified predictors of 2-year lymphedema using eligible variables involving demographics, comorbidities, and complications. Elixhauser score was defined as a comorbidity index based on International Classification of Diseases codes used in hospital settings. RESULTS: Overall, 5.2% (n = 3409) of the breast cancer postmastectomy patients experienced a lymphedema-related event within 2 years of initial surgery. Over time, 2-year postmastectomy lymphedema rates have more than doubled from 4.62% in 2010 to 9.75% in 2016 (P < 0.001). Two-year postmastectomy lymphedema rates varied significantly by mastectomy procedure type: 5.69% of the mastectomy-only procedures, 5.96% of the mastectomies with lymph node biopsies, and 7.83% of the mastectomies with lymph node dissections (P < 0.0001). Full mastectomies had a greater 2-year lymphedema rate of 7.31% when compared with partial mastectomies with 2.79% (P < 0.0001). The top predictive risk factors for a lymphedema-related event included higher Elixhauser score, prolonged hospitalization for mastectomy, more recent mastectomy procedure, obesity, younger age, non-Asian race, Medicaid insurance, and hypertension (all P's < 0.01). CONCLUSIONS: Although more recent postmastectomy lymphedema rates may not be as high as historical estimates, the 2-year postmastectomy lymphedema rates have more than doubled from 2010 to 2016 requiring further elucidation as well as continued focus on treatment. Furthermore, risk factors were identified that predispose postmastectomy breast cancer patients to developing lymphedema. Given these findings, perioperative screening seems warranted to proactively identify, educate, and monitor postmastectomy patients at greatest risk of future lymphedema development.

Five-Year Outcomes after On-Pump and Off-Pump Coronary-Artery Bypass.

BACKGROUND: Coronary-artery bypass grafting (CABG) surgery may be performed either with cardiopulmonary bypass (on pump) or without cardiopulmonary bypass (off pump). We report the 5-year clinical outcomes in patients who had been included in the Veterans Affairs trial of on-pump versus off-pump CABG. METHODS: From February 2002 through June 2007, we randomly assigned 2203 patients at 18 medical centers to undergo either on-pump or off-pump CABG, with 1-year assessments completed by May 2008. The two primary 5-year outcomes were death from any cause and a composite outcome of major adverse cardiovascular events, defined as death from any cause, repeat revascularization (CABG or percutaneous coronary intervention), or nonfatal myocardial infarction. Secondary 5-year outcomes included death from cardiac causes, repeat revascularization, and nonfatal myocardial infarction. Primary outcomes were assessed at a P value of 0.05 or less, and secondary outcomes at a P value of 0.01 or less. RESULTS: The rate of death at 5 years was 15.2% in the off-pump group versus 11.9% in the on-pump group (relative risk, 1.28; 95% confidence interval [CI], 1.03 to 1.58; P=0.02). The rate of major adverse cardiovascular events at 5 years was 31.0% in the off-pump group versus 27.1% in the on-pump group (relative risk, 1.14; 95% CI, 1.00 to 1.30; P=0.046). For the 5-year secondary outcomes, no significant differences were observed: for nonfatal myocardial infarction, the rate was 12.1% in the off-pump group and 9.6% in the on-pump group (P=0.05); for death from cardiac causes, the rate was 6.3% and 5.3%, respectively (P=0.29); for repeat revascularization, the rate was 13.1% and 11.9%, respectively (P=0.39); and for repeat CABG, the rate was 1.4% and 0.5%, respectively (P=0.02). CONCLUSIONS: In this randomized trial, off-pump CABG led to lower rates of 5-year survival and event-free survival than on-pump CABG.

Laparoscopic versus open surgery: a systematic review evaluating Cochrane systematic reviews.

BACKGROUND: Laparoscopic surgical procedures (LSP) have grown in popularity due to their purported benefits of improved effectiveness and efficiency. This study summarizes the Cochrane systematic reviews' (CSRs') evidence comparing the use of LSP versus open procedures used for surgical patient management and comparing the CSRs' quality and consistency of LSP evidence reported across time and different surgical specialties. METHODS: The Cochrane Database was searched to identify CSRs comparing LSP versus open procedures; 36 CSRs and 15 CSR protocols were found as of February 16, 2016. Each CSR's clinical outcomes and major conclusions were evaluated; CSR's quality and completeness were assessed using PRISMA and AMSTAR criteria. Overall, CSRs' reporting variations across specialties and trends over time were summarized. RESULTS: A weighted analysis across all 36 CSRs found improved outcomes with LSP (odds ratio 0.90; 95% confidence interval 0.88, 0.92). Substantial CSR variation was found in the patient inclusion/exclusion criteria and clinical endpoints used. Individually, most CSR analyses showed no significant difference (65.4%) between LSP versus open procedures; 25.8% showed a LSP benefit versus 8.9% an open benefit. As a major conclusion, a positive LSP impact was documented by 8/36 (22.2%) CSRs; but only half of these CSRs decisively concluded that there was a LSP advantage. Undeclared conflicts of interest were identified in 9/36 CSRs (25.0%), raising the potential for a reporting bias. Both CSR variabilities (i.e., missing population, intervention, comparison, outcome, study design statements) and PRISMA-related deficiencies were documented. CONCLUSIONS: Overall, CSR evidence supports a LSP advantage; however, clinical decisions must be driven by CSR procedure-specific evidence. Variations and inconsistencies in CSR design and reporting identified future opportunities to improve CSR quality by increasing the methodological transparency, standardizing CSR reporting, and documenting comprehensively any non-financial conflicts of interest (i.e., ongoing research and historical publications) for all CSR team members.

Evaluation of VTE prophylaxis and the impact of alternate regimens on post-operative bleeding and thrombotic complications following bariatric procedures.

BACKGROUND: Studies examining utilization and impact of venous thromboembolism (VTE) chemoprophylaxis for patients undergoing bariatric surgery are limited. Determination of the optimal prophylactic regimen to minimize complications is crucial. METHODS: The Cerner Health Facts database from 2003 to 2013 was queried using ICD-9 codes to identify patients undergoing laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB). VTE chemoprophylaxis regimens were divided into pre-operative alone (PreP), post-operative alone (PostP), both pre-operative and post-operative (PPP), or no prophylaxis (NP). Specific chemoprophylaxis agents were compared. Comparisons in inpatient clinical outcomes were based on univariate analysis and multivariable logistic regression when appropriate. RESULTS: We identified 11,860 patients who underwent LSG and RYGB. 634 (5.35%) had PreP, 4593 (38.73%) had PostP, 2646 (22.31%) had PPP, and 3987 (33.62%) had NP. The overall rates of transfusion, DVT, and PE were 2.48, 0.27, and 0.18%, respectively. Patients without chemoprophylaxis had higher rate of DVT compared to any chemoprophylaxis (0.58 vs 0.11%, p < 0.0001), without any significant difference in PE rate. Patients with pre-operative chemoprophylaxis were more likely to receive transfusion compared to patients with post-operative prophylaxis alone (OR 1.98, 95% CI 1.28-3), without significant difference in having VTE. When examining heparin versus enoxaparin versus mixed regimen in the PostP group, mixed regimen was associated with increased transfusion requirements (p < 0.001). CONCLUSIONS: Bariatric surgical VTE chemoprophylaxis utilization is inconsistent. In this study, post-operative VTE chemoprophylaxis was associated with decreased VTE events compared to NP, while minimizing bleeding compared to PreP. Mixed therapy using heparin and enoxaparin was associated with more bleeding.

Long-Term Post-CABG Survival: Performance of Clinical Risk Models Versus Actuarial Predictions.

BACKGROUND/AIM: Clinical risk models are commonly used to predict short-term coronary artery bypass grafting (CABG) mortality but are less commonly used to predict long-term mortality. The added value of long-term mortality clinical risk models over traditional actuarial models has not been evaluated. To address this, the predictive performance of a long-term clinical risk model was compared with that of an actuarial model to identify the clinical variable(s) most responsible for any differences observed. METHODS: Long-term mortality for 1028 CABG patients was estimated using the Hannan New York State clinical risk model and an actuarial model (based on age, gender, and race/ethnicity). Vital status was assessed using the Social Security Death Index. Observed/expected (O/E) ratios were calculated, and the models' predictive performances were compared using a nested c-index approach. Linear regression analyses identified the subgroup of risk factors driving the differences observed. RESULTS: Mortality rates were 3%, 9%, and 17% at one-, three-, and five years, respectively (median follow-up: five years). The clinical risk model provided more accurate predictions. Greater divergence between model estimates occurred with increasing long-term mortality risk, with baseline renal dysfunction identified as a particularly important driver of these differences. CONCLUSIONS: Long-term mortality clinical risk models provide enhanced predictive power compared to actuarial models. Using the Hannan risk model, a patient's long-term mortality risk can be accurately assessed and subgroups of higher-risk patients can be identified for enhanced follow-up care. More research appears warranted to refine long-term CABG clinical risk models.

Long-term mortality rates (>8-year) improve as compared to the general and obese population following bariatric surgery.

INTRODUCTION: Sparse data are available on long-term patient mortality following bariatric surgery as compared to the general population. The purpose of this study was to assess long-term mortality rates and identify risk factors for all-cause mortality following bariatric surgery. METHODS: New York State (NYS) Planning and Research Cooperative System (SPARCS) longitudinal administrative data were used to identify 7,862 adult patients who underwent a primary laparoscopic bariatric surgery from 1999 to 2005. The Social Security Death Index database identified >30-day mortalities. Risk factors for mortality were screened using a univariate Cox proportional hazard (PH) model and analyzed using a multiple PH model. Based on age, gender, and race/ethnicity, actuarial projections for NYS mortality rates obtained from Centers of Disease Control were compared to the actual post-bariatric surgery mortality rates observed. RESULTS: The mean bariatric mortality rate was 2.5 % with 8-14 years of follow-up. Mean time to death ranged from 4 to 6 year and did not differ by operation (p = 0.073). From 1999 to 2010, the actuarial mortality rate predicted for the general NYS population was 2.1 % versus the observed 1.5 % for the bariatric surgery population (p = 0.005). Extrapolating to 2013, demonstrated the actuarial mortality predictions at 3.1 % versus the bariatric surgery patients' observed morality rate of 2.5 % (p = 0.01). Risk factors associated with an earlier time to death included: age, male gender, Medicare/Medicaid insurance, congestive heart failure, rheumatoid arthritis, pulmonary circulation disorders, and diabetes. No procedure-specific or perioperative complication impact for time-to-death was found. CONCLUSION: Long-term mortality rate of patients undergoing bariatric surgery significantly improves as compared to the general population regardless of bariatric operation performed. Additionally, perioperative complications do not increase long-term mortality risk. This study did identify specific patient risk factors for long-term mortality. Special attention and consideration should be given to these "at risk" patient sub-populations.

Usefulness of two clinical chorioamnionitis definitions in predicting neonatal infectious outcomes: a systematic review.

OBJECTIVE: To assess the usefulness of two definitions of acute clinical chorioamnionitis (ACCA) in predicting risk of neonatal infectious outcomes (NIO) and mortality, the first definition requiring maternal fever alone (Fever), and the second requiring ≥ 1 Gibbs criterion besides fever (Fever + 1). STUDY DESIGN: PubMed, Web of Science, and the Cochrane Database of Systematic Reviews were searched from January 1, 1979 to April 9, 2013. Twelve studies were reviewed (of 316 articles identified): three studies with term patients, four with preterm premature rupture of membranes (PPROM) patients, and five mixed studies with mixed gestational ages and/or membrane status (intact and/or ruptured). RESULTS: Both definitions demonstrated an increased NIO risk for ACCA versus non-ACCA patients, with an odds ratio increase for the Fever + 1 definition that was about twofold larger than the Fever definition. CONCLUSION: As the Fever definition demonstrated increased NIO risk for ACCA versus non-ACCA patients, the Fever alone ACCA definition should be used to trigger future clinical treatment in many clinical situations.

Gender dysphoria and gender-affirming surgery: The New York state experience.

BACKGROUND: Transgender and gender nonconforming (TGNC) individuals experience incongruence between their self-identified gender versus their birth-assigned sex. In some cases, TGNC patients undergo gender-affirming surgical (GAS) procedures. Although GAS is an evolving surgical field, there is currently limited literature documenting patient characteristics and procedures. Addressing this knowledge gap, this retrospective cohort analysis described the characteristics of New York State's TGNC residents with gender dysphoria (GD) diagnosis, including patients undergoing at least one gender-affirming surgical procedure. METHODS: Using the New York Statewide Planning and Research Cooperative System (SPARCS) database from 2002 to 2018, we identified patients' first-time TCNC records and their risk characteristics. Patients who received GAS procedures were sub-classified as top-only, bottom-only, or combined top/bottom procedures and were compared with TGNC patients who did not receive GAS. RESULTS: Of 24,615 records extracted from TGNC SPARCS database, 11,427 (46.4%) were transmasculine (female-to-male) and 13,188 (53.6%) were transfeminine (male-to-female). Overall, 2.73% of transgender patients received at least one GAS procedure. Of these patients, 78.2% had masculinizing and 21.8% had feminizing surgeries. After a diagnosis of GD, the positive predictors for a GAS-based procedure included female birth sex, pediatric age (<18 years) or older age (60+ years), commercial insurance coverage, and Hispanic race. In contrast, negative GAS predictors included male birth sex and government insurance coverage (i.e., Medicare and Medicaid). CONCLUSIONS: Compared with transgender women, transgender men were more likely to receive at least one GAS procedure. Because the race, ethnicity, and payor status of TGNC patients can impact GAS treatment rates, additional research is warranted to examine post-diagnosis GAS treatment disparities among TGNC patients.

Posttraumatic Stress Disorder Is Associated With Elevated Risk of Incident Stroke and Transient Ischemic Attack in Women Veterans.

BACKGROUND: Posttraumatic stress disorder (PTSD) has been associated with ischemic heart disease in women veterans, but evidence for associations with other cardiovascular disorders remains limited in this population. This retrospective longitudinal cohort study evaluated the association of PTSD with incident stroke/transient ischemic attack (TIA) in women veterans. METHODS AND RESULTS: Veterans Health Administration electronic health records were used to identify women veterans aged ≥18 years engaged with Veterans Health Administration health care from January 1, 2000 to December 31, 2019. We identified women veterans with and without PTSD without a history of stroke or TIA at start of follow-up. Propensity score matching was used to match groups on age, race or ethnicity, traditional cardiovascular risk factors, female-specific risk factors, a range of mental and physical health conditions, and number of prior health care visits. PTSD, stroke, TIA, and risk factors used in propensity score matching were based on diagnostic codes. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% CIs for associations of PTSD with an incident stroke/TIA composite. Subanalyses considered stroke and TIA separately, plus age- and race- or ethnicity-stratified analyses were carried out. The analytic sample included 208 092 women veterans (104 046 with and 104 046 without PTSD). PTSD was associated with a greater rate of developing stroke/TIA (HR, 1.33 [95% CI, 1.25-1.42], P<0.001). This elevated risk was especially pronounced in women <50 years old and in Hispanic/Latina women. CONCLUSIONS: Findings indicate a strong association of PTSD with incident stroke/TIA in women veterans. Research is needed to determine whether addressing PTSD and its downstream consequences can offset this risk.

Off-Pump coronary artery bypass surgery is associated with worse arterial and saphenous vein graft patency and less effective revascularization: Results from the Veterans Affairs Randomized On/Off Bypass (ROOBY) trial.

BACKGROUND: The Department of Veterans Affairs Randomized On/Off Bypass (ROOBY) trial compared clinical and angiographic outcomes in off-pump versus on-pump coronary artery bypass graft (CABG) surgery to ascertain the relative efficacy of the 2 techniques. METHODS AND RESULTS: From February 2002 to May 2007, the ROOBY trial randomized 2203 patients to off-pump versus on-pump CABG. Follow-up angiography was obtained in 685 off-pump (62%) and 685 on-pump (62%) patients. Angiograms were analyzed (blinded to treatment) for FitzGibbon classification (A=widely patent, B=flow limited, O=occluded) and effective revascularization. Effective revascularization was defined as follows: All 3 major coronary territories with significant disease were revascularized by a FitzGibbon A-quality graft to the major diseased artery, and there were no new postanastomotic lesions. Off-pump CABG resulted in lower FitzGibbon A patency rates than on-pump CABG for arterial conduits (85.8% versus 91.4%; P=0.003) and saphenous vein grafts (72.7% versus 80.4%; P<0.001). Fewer off-pump patients were effectively revascularized (50.1% versus 63.9% on-pump; P<0.001). Within each major coronary territory, effective revascularization was worse off pump than on pump (all P≤0.001). The 1-year adverse cardiac event rate was 16.4% in patients with ineffective revascularization versus 5.9% in patients with effective revascularization (P<0.001). CONCLUSIONS: Off-pump CABG resulted in significantly lower FitzGibbon A patency for arterial and saphenous vein graft conduits and less effective revascularization than on-pump CABG. At 1 year, patients with less effective revascularization had higher adverse event rates. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov. Unique identifier: NCT00032630.

Report from a quality assurance program on patients undergoing the MILD procedure.

OBJECTIVES: To characterize trends in pain and functional outcomes and identify risk factors in patients with lumbar spinal stenosis (LSS) and neurogenic claudication undergoing the "Minimally Invasive Lumbar Decompression" (MILD) procedure. DESIGN: Retrospective observational cohort study. SETTING: Academic multidisciplinary pain center at Stony Brook Medicine. SUBJECTS: Patients undergoing the MILD procedure from October 2010 to November 2012. METHODS: De-identified perioperative, pain and function related data for 50 patients undergoing MILD were extracted from the Center for Pain Management's quality assessment database. Data included numerical rating scale (NRS), symptom severity and physical function (Zurich Claudication Questionnaire), functional status (Oswestry Disability Index [ODI]), pain interference scores (National Institutes of Health Patient-Reported Outcomes Measurement Information System [PROMIS]), and patients' self-reported low back and lower extremity pain distribution. RESULTS: No MILD patient incurred procedure-related complications. Average NRS scores decreased postoperatively and 64.3% of patients reported less pain at 3 months. Clinically meaningful functional ODI improvements of at least 20% from baseline were present in 25% of the patients at 6 months. Preliminary analysis of changes in PROMIS scores at 3 months revealed that pre-MILD "severe" lumbar canal stenosis may be associated with high risk of "no improvement." No such impact was observed for NRS or ODI outcomes. CONCLUSION: Overall, pain is reduced and functional status improved in LSS patients following the MILD procedure at 3 and 6 months. Given the small sample size, it is not yet possible to identify patient subgroups at risk for "no improvement." Continued follow-up of longer-term outcomes appears warranted to develop evidence-based patient selection criteria.

Trends in Cardiovascular Disease Mortality in US Women Veterans vs Civilians.

Importance: Cardiovascular disease (CVD) remains the leading cause of death in the US. Women veterans have higher rates of CVD compared with civilian US women; however, analyses of recent trends in mortality from cardiac disease for women veterans are lacking. Objective: To investigate trends in cardiac disease mortality among women veterans over approximately the past 2 decades and compare rates with those for civilian women. Design, Setting, and Participants: In this retrospective longitudinal cohort study, US Veterans Health Administration (VHA) electronic health record data, linked with the National Death Index, were analyzed for CVD trends and rates of cardiac disease mortality among women veterans (aged 18 years or older) with VHA health care encounters from January 1, 2000, to December 31, 2017. These data were compared with a national cohort of civilian women (aged 15 years or older) in the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database, which provides cause-of-death data using death certificates for all US residents. The data analysis was performed between March 10, 2021, and November 28, 2022. Exposure: Cardiac disease mortality among women veterans and civilian women. Main Outcomes and Measures: Cardiac disease mortality was based on International Classification of Diseases, Tenth Revision diagnostic codes (I00-I09, I11, I13, and I20-I51 as defined by CDC WONDER). For women veterans and civilian women, crude and age-adjusted cardiac disease mortality rates (per 100 000 life-years) and 95% CIs were calculated, with the 2000 US general population as the reference for age-adjusted rates. Results: From 2000 to 2017, 817 912 women veterans engaged with VHA health care (mean [SD] age, 45.7 [17.1] years), and 19 022 cardiac disease deaths were identified (22.4% of total deaths). The crude and age-adjusted cardiac disease mortality rates, respectively, per 100 000 life-years were 200.2 (95% CI, 181.0-221.0) and 197.6 (95% CI, 175.2-222.0) in 2000 and 196.0 (95% CI, 186.1-206.4) and 208.1 (95% CI, 196.4-220.4) in 2017, reflecting stable crude rates and a 5.3% increase in age-adjusted rates. For civilian women, the crude and age-adjusted rates decreased over time from 320.7 (95% CI, 319.7-321.8) and 268.1 (95% CI, 267.3-269.0) in 2000 to 220.9 (95% CI, 220.1-221.7) and 164.7 (95% CI, 164.1-165.3) in 2017. Conclusions and Relevance: In this cohort study comparing women veterans and civilian women, cardiac disease mortality rates for women veterans did not exhibit the improvements seen for civilian women during the nearly 2-decade study period. Further research and actionable clinical interventions are warranted to improve cardiovascular care for women veterans, who represent the fastest growing group of patients within the VHA health care system.

On-pump versus off-pump coronary-artery bypass surgery.

BACKGROUND: Coronary-artery bypass grafting (CABG) has traditionally been performed with the use of cardiopulmonary bypass (on-pump CABG). CABG without cardiopulmonary bypass (off-pump CABG) might reduce the number of complications related to the heart-lung machine. METHODS: We randomly assigned 2203 patients scheduled for urgent or elective CABG to either on-pump or off-pump procedures. The primary short-term end point was a composite of death or complications (reoperation, new mechanical support, cardiac arrest, coma, stroke, or renal failure) before discharge or within 30 days after surgery. The primary long-term end point was a composite of death from any cause, a repeat revascularization procedure, or a nonfatal myocardial infarction within 1 year after surgery. Secondary end points included the completeness of revascularization, graft patency at 1 year, neuropsychological outcomes, and the use of major resources. RESULTS: There was no significant difference between off-pump and on-pump CABG in the rate of the 30-day composite outcome (7.0% and 5.6%, respectively; P=0.19). The rate of the 1-year composite outcome was higher for off-pump than for on-pump CABG (9.9% vs. 7.4%, P=0.04). The proportion of patients with fewer grafts completed than originally planned was higher with off-pump CABG than with on-pump CABG (17.8% vs. 11.1%, P<0.001). Follow-up angiograms in 1371 patients who underwent 4093 grafts revealed that the overall rate of graft patency was lower in the off-pump group than in the on-pump group (82.6% vs. 87.8%, P<0.01). There were no treatment-based differences in neuropsychological outcomes or short-term use of major resources. CONCLUSIONS: At 1 year of follow-up, patients in the off-pump group had worse composite outcomes and poorer graft patency than did patients in the on-pump group. No significant differences between the techniques were found in neuropsychological outcomes or use of major resources. (ClinicalTrials.gov number, NCT00032630.).

Ten-Year Outcomes of Off-Pump vs On-Pump Coronary Artery Bypass Grafting in the Department of Veterans Affairs: A Randomized Clinical Trial.

IMPORTANCE: The long-term benefits of off-pump ("beating heart") vs on-pump coronary artery bypass grafting (CABG) remain controversial. OBJECTIVE: To evaluate the 10-year outcomes and costs of off-pump vs on-pump CABG in the Department of Veterans Affairs (VA) Randomized On/Off Bypass (ROOBY) trial. DESIGN, SETTING, AND PARTICIPANTS: From February 27, 2002, to May 7, 2007, 2203 veterans in the ROOBY trial were randomly assigned to off-pump or on-pump CABG procedures at 18 participating VA medical centers. Per protocol, the veterans were observed for 10 years; the 10-year, post-CABG clinical outcomes and costs were assessed via centralized abstraction of electronic medical records combined with merges to VA and non-VA databases. With the use of an intention-to-treat approach, analyses were performed from May 7, 2017, to December 9, 2021. INTERVENTIONS: On-pump and off-pump CABG procedures. MAIN OUTCOMES AND MEASURES: The 10-year coprimary end points included all-cause death and a composite end point identifying patients who had died or had undergone subsequent revascularization (ie, percutaneous coronary intervention [PCI] or repeated CABG); these 2 end points were measured dichotomously and as time-to-event variables (ie, time to death and time to composite end points). Secondary 10-year end points included PCIs, repeated CABG procedures, changes in cardiac symptoms, and 2018-adjusted VA estimated costs. Changes from baseline to 10 years in post-CABG, clinically relevant cardiac symptoms were evaluated for New York Heart Association functional class, Canadian Cardiovascular Society angina class, and atrial fibrillation. Outcome differences were adjudicated by an end points committee. Given that pre-CABG risks were balanced, the protocol-driven primary and secondary hypotheses directly compared 10-year treatment-related effects. RESULTS: A total of 1104 patients (1097 men [99.4%]; mean [SD] age, 63.0 [8.5] years) were enrolled in the off-pump group, and 1099 patients (1092 men [99.5%]; mean [SD] age, 62.5 [8.5] years) were enrolled in the on-pump group. The 10-year death rates were 34.2% (n = 378) for the off-pump group and 31.1% (n = 342) for the on-pump group (relative risk, 1.05; 95% CI, 0.99-1.11; P = .12). The median time to composite end point for the off-pump group (4.6 years; IQR, 1.4-7.5 years) was approximately 4.3 months shorter than that for the on-pump group (5.0 years; IQR, 1.8-7.9 years; P = .03). No significant 10-year treatment-related differences were documented for any other primary or secondary end points. After the removal of conversions, sensitivity analyses reconfirmed these findings. CONCLUSIONS AND RELEVANCE: No off-pump CABG advantages were found for 10-year death or revascularization end points; the time to composite end point was lower in the off-pump group than in the on-pump group. For veterans, in the absence of on-pump contraindications, a case cannot be made for supplanting the traditional on-pump CABG technique with an off-pump approach.

Off-Pump Coronary Artery Bypass Grafting: Department of Veteran Affairs' Use and Outcomes.

Background Coronary artery bypass can be performed off pump (OPCAB) without cardiopulmonary bypass. However, trends over time for OPCAB versus on-pump (ONCAB) use and long-term outcome has not been reported, nor has their long-term outcome been compared. Methods and Results We queried the national Veterans Affairs database (2005-2019) to identify isolated coronary artery bypass procedures. Procedures were classified as OPCAB on ONCAB using the as-treated basis. Trend analyses were performed to evaluate longitudinal changes in the preference for OPCAB. The median follow-up period was 6.6 (3.5-10) years. An inverse probability weighted Cox model was used to compare all-cause mortality between OPCAB and ONCAB. From 47 685 patients, 6759 (age 64±8 years) received OPCAB (14%). OPCAB usage declined from 16% (2005-2009) to 8% (2015-2019). Patients with triple vessel disease who received OPCAB received a lower mean number of grafts (2.8±0.8 versus 3.2±0.8; P<0.01). The ONCAB 5-, 10-, and 15-year survival rates were 82.9% (82.5-83.3), 60.4% (59.8-61.1), and 37.2% (36.1-38.4); correspondingly, OPCAB rates were 80.7% (79.7-81.7), 57.4% (56-58.7), and 34.1% (31.7-36.6) (P<0.01). OPCAB was associated with increased risk-adjusted all-cause mortality (hazard ratio, 1.15 [1.13-1.18]; P<0.01) and myocardial infarction (incident rate ratio, 1.16 [1.05-1.28]; P<0.01). Conclusions Over 15 years, OPCAB use declined considerably in Veterans Affairs medical centers. In Veterans Affairs hospitals, late all-cause mortality and myocardial infarction rates were higher in the OPCAB cohort.

Cardiac surgical simulation program during general surgery residency increases resident physician exposure to cardiac surgery and technical expertise.

Objective: The changing surgical education landscape in surgical training pathways greatly diminished cardiac surgical knowledge, interest, and skills among general surgery trainees. To address this issue, our department developed a cardiac surgery simulation program. Methods: All simulation sessions lasted at least 2 hours and occurred during resident physician protected education time. Participants were postgraduate year 2 through 5 general surgery residents assisted by staff and led by cardiac surgery faculty. Five of the 6 sessions were porcine heart wet labs simulating coronary anastomoses, surgical aortic valve replacement, mitral valve repair and replacement, and left ventricular assist device implantation. The transcatheter aortic valve replacement session was designed as a video simulation and a manikin for wire manipulation and implantation. At the end of each lab, all participants were surveyed about their experiences. Results: An average of 10 resident physicians participated in each session (range, 8-13), for a total of 120 simulation hours. One hundred percent of residents surveyed agreed that the labs improved knowledge and understanding of the disease process, improved understanding of cardiac surgical principles, and helped acquire skills for surgical residency and treatment. Factors that residents cited for increased attendance rate included protected education time, hands-on experience, and a high faculty-to-resident ratio. Conclusions: This program successfully demonstrates that cardiac surgery training and simulation can be integrated into general surgery residency programs, despite the lack of cardiac surgery requirements. Additional metrics for future study includes technical grades on resident physicians' performance to further assess the value of this program.

Academic medicine's glass ceiling: Author's gender in top three medical research journals impacts probability of future publication success.

INTRODUCTION: In December 2017, Lancet called for gender inequality investigations. Holding other factors constant, trends over time for significant author (i.e., first, second, last or any of these authors) publications were examined for the three highest-impact medical research journals (i.e., New England Journal of Medicine [NEJM], Journal of the American Medical Association [JAMA], and Lancet). MATERIALS AND METHODS: Using randomly sampled 2002-2019 MEDLINE original publications (n = 1,080; 20/year/journal), significant author-based and publication-based characteristics were extracted. Gender assignment used internet-based biographies, pronouns, first names, and photographs. Adjusting for author-specific characteristics and multiple publications per author, generalized estimating equations tested for first, second, and last significant author gender disparities. RESULTS: Compared to 37.23% of 2002 - 2019 U.S. medical school full-time faculty that were women, women's first author publication rates (26.82% overall, 15.83% NEJM, 29.38% Lancet, and 35.39% JAMA; all p < 0.0001) were lower. No improvements over time occurred in women first authorship rates. Women first authors had lower Web of Science citation counts and co-authors/collaborating author counts, less frequently held M.D. or multiple doctoral-level degrees, less commonly published clinical trials or cardiovascular-related projects, but more commonly were North American-based and studied North American-based patients (all p < 0.05). Women second and last authors were similarly underrepresented. Compared to men, women first authors had lower multiple publication rates in these top journals (p < 0.001). Same gender first/last authors resulted in higher multiple publication rates within these top three journals (p < 0.001). DISCUSSION: Since 2002, this authorship "gender disparity chasm" has been tolerated across all these top medical research journals. Despite Lancet's 2017 call to arms, furthermore, the author-based gender disparities have not changed for these top medical research journals - even in recent times. Co-author gender alignment may reduce future gender inequities, but this promising strategy requires further investigation.
