RESUMO
INTRODUCTION: Medicaid expansion's (ME) impact on postoperative outcomes after abdominal surgery remains poorly defined. We aimed to evaluate ME's effect on surgical morbidity, mortality, and readmissions in a state that expanded Medicaid (Virginia) compared to a state that did not (Tennessee) over the same time period. METHODS: Virginia Surgical Quality Collaborative (VSQC) American College of Surgeons National Surgical Quality Improvement Program data for Medicaid, uninsured, and private insurance patients undergoing abdominal procedures before Virginia's ME (3/22/18-12/31/18) were compared with post-ME (1/1/19-12/31/19), as were corresponding non-ME state Tennessee Surgical Quality Collaborative (TSQC) data for the same 2018 and 2019 time periods. Postexpansion odds ratios for 30-d morbidity, 30-d mortality, and 30-d unplanned readmission were estimated using propensity score-adjusted logistic regression models. RESULTS: In Virginia, 4753 abdominal procedures, 2097 pre-ME were compared to 2656 post-ME. In Tennessee, 5956 procedures, 2484 in 2018 were compared to 3472 in 2019. VSQC's proportion of Medicaid population increased following ME (8.9% versus 18.8%, P < 0.001) while uninsured patients decreased (20.4% versus 6.4%, P < 0.001). Post-ME VSQC had fewer 30-d readmissions (12.2% versus 6.0%, P = 0.013). Post-ME VSQC Medicaid patients had significantly lower probability of morbidity (-8.18, 95% confidence interval: -15.52 â¼ -0.84, P = 0.029) and readmission (-6.92, 95% confidence interval: -12.56 â¼ -1.27, P = 0.016) compared to pre-ME. There were no differences in probability of morbidity or readmission in the TSQC Medicaid population between study periods (both P > 0.05); there were no differences in mortality between study periods in VSQC and TSQC patient populations (both P > 0.05). CONCLUSIONS: ME was associated with decreased 30-d morbidity and unplanned readmissions in the VSQC. Data-driven policies accounting for ME benefits should be considered.

OBJECTIVE: National Institutes of Health (NIH) funding for academic (noncardiac) thoracic surgeons at the top-140 NIH-funded institutes in the United States was assessed. We hypothesized that thoracic surgeons have difficulty in obtaining NIH funding in a difficult funding climate. METHODS: The top-140 NIH-funded institutes' faculty pages were searched for noncardiac thoracic surgeons. Surgeon data, including gender, academic rank, and postfellowship training were recorded. These surgeons were then queried in NIH Research Portfolio Online Reporting Tools Expenditures and Results for their funding history. Analysis of the resulting grants (1980-2019) included grant type, funding amount, project start/end dates, publications, and a citation-based Grant Impact Metric to evaluate productivity. RESULTS: A total of 395 general thoracic surgeons were evaluated with 63 (16%) receiving NIH funding. These 63 surgeons received 136 grants totaling $228 million, resulting in 1772 publications, and generating more than 50,000 citations. Thoracic surgeons have obtained NIH funding at an increasing rate (1980-2019); however, they have a low percentage of R01 renewal (17.3%). NIH-funded thoracic surgeons were more likely to have a higher professorship level. Thoracic surgeons perform similarly to other physician-scientists in converting K-Awards into R01 funding. CONCLUSIONS: Contrary to our hypothesis, thoracic surgeons have received more NIH funding over time. Thoracic surgeons are able to fill the roles of modern surgeon-scientists by obtaining NIH funding during an era of increasing clinical demands. The NIH should continue to support this mission.

BACKGROUND: There is a strong association between socioeconomic status and surgical outcomes; however, the optimal method for socioeconomic risk-stratification remains elusive. We aimed to compare 2 metrics of socioeconomic ranking by ZIP code, the Distressed Communities Index, and the Area Deprivation Index and their association with surgical outcomes. METHODS: This retrospective study included all general surgery cases performed at a single institution from 2005 to 2015. Each patient was assigned Distressed Communities Index and Area Deprivation Index scores based on ZIP code. Both indices are normalized composite measures of socioeconomic status derived from census data. Primary outcome was 30-day morbidity; secondary outcomes included long-term mortality and cost, stratified by socioeconomic status. The utility of the addition of each metric to the American College of Surgeons National Surgical Quality Improvement Program risk calculator was assessed. RESULTS: The 9,843 patients had normally distributed Distressed Communities Index (47.3 ± 22.4) and Area Deprivation Index (35.4 ± 19.0). Patients who experienced any complication or readmission had significantly higher Distressed Communities Index (48.6 vs 47.1, P = .04) and Area Deprivation Index (37.2 vs 35.1, P = .002). Risk-adjusted models demonstrated that only Area Deprivation Index independently predicted postoperative complications (odds ratio 1.11, P = .02), improved the discrimination of risk-stratification when added to the American College of Surgeons National Surgical Quality Improvement Program risk calculator (area under curve 0.758-0.790, P = .02), and was associated with hospitalization cost ($1,811 ± 856/quartile, P = .03). CONCLUSION: Area Deprivation Index provides improved socioeconomic risk-adjustment in this surgical population. The addition of Area Deprivation Index to risk-stratification tools would allow us to better inform our patients of their expected postoperative courses, more accurately account for the increased cost of providing their care, and identify patients and regions that are most in need of improvements in health and healthcare.

BACKGROUND: A significant percentage of patients who acutely develop high-grade atrioventricular block after valve surgery will ultimately recover, yet the ability to predict recovery is limited. The purpose of this analysis was to evaluate the cost-effectiveness of two different management strategies for the timing of permanent pacemaker implantation for new heart block after valve surgery. METHODS: A cost-effectiveness model was developed using costs and probabilities of short- and long-term complications of pacemaker placement, short-term atrioventricular node recovery, intensive care unit stays, and long-term follow-up. We aggregated the total expected cost and utility of each option over a 20-y period. Quality-adjusted survival with a pacemaker was estimated from the literature and institutional patient-reported outcomes. Primary decision analysis was based on an expected recovery rate of 36.7% at 12 d with timing of pacemaker implantation: early placement (5 d) versus watchful waiting for 12 d. RESULTS: A strategy of watchful waiting was more costly ($171,798 ± $45,695 versus $165,436 ± $52,923; P < 0.0001) but had a higher utility (9.05 ± 1.36 versus 8.55 ± 1.33 quality-adjusted life years; P < 0.0001) than an early pacemaker implantation strategy. The incremental cost-effectiveness ratio of watchful waiting was $12,724 per quality-adjusted life year. The results are sensitive to differences in quality-adjusted survival and rates of recovery of atrioventricular node function. CONCLUSIONS: Watchful waiting for pacemaker insertion is a cost-effective management strategy compared with early placement for acute atrioventricular block after valve surgery. Although this is cost-effective from a population perspective, clinical risk scores predicting recovery will aid in personalized decision-making.

BACKGROUND: Limited multi-institutional data evaluating minimally invasive cardiac surgery (MICS) coronary artery bypass surgery (CABG) outcomes have raised concern for increased resource utilization compared with standard sternotomy. The purpose of this study was to assess short-term outcomes and resource utilization with MICS CABG in a propensity-matched regional cohort. METHODS: Isolated CABG patients (2012-2019) were extracted from a regional Society of Thoracic Surgeons database. Patients were stratified by MICS CABG vs open CABG via sternotomy, propensity-score matched 1:2 to balance baseline differences, and compared by univariate analysis. RESULTS: Of 26,255 isolated coronary artery bypass graft patients, 139 MICS CABG and 278 open CABG patients were well balanced after matching. There was no difference in the operative mortality rate (2.2% open vs 0.7% MICS CABG, P = .383) or major morbidity (7.9% open vs 7.2% MICS CABG, P = .795). However, open CABG patients received more blood products (22.2% vs 12.2%, P = .013), and had longer intensive care unit (45 vs 30 hours, P = .049) as well as hospital lengths of stay (7 vs 6 days, P = .005). Finally, median hospital cost was significantly higher in the open CABG group ($35,011 vs $27,906, P < .001) compared with MICS CABG. CONCLUSIONS: Open CABG via sternotomy and MICS CABG approaches are associated with similar, excellent perioperative outcomes. However, MICS CABG was associated with fewer transfusions, shorter length of stay, and â¼$7000 lower hospital cost, a superior resource utilization profile that improves patient care and lowers cost.

OBJECTIVE: We hypothesize the Distressed Communities Index (DCI), a composite socioeconomic ranking by ZIP code, will predict risk-adjusted outcomes after surgery. SUMMARY OF BACKGROUND DATA: Socioeconomic status affects surgical outcomes; however, the American College of Surgeons National Surgery Quality Improvement Program (ACS NSQIP) database does not account for these factors. METHODS: All ACS NSQIP patients (17,228) undergoing surgery (2005 to 2015) at a large academic institution were paired with the DCI, which accounts for unemployment, education level, poverty rate, median income, business growth, and housing vacancies. Developed by the Economic Innovation Group, DCI scores range from 0 (no distress) to 100 (severe distress). Multivariable regressions were used to evaluate ACS NSQIP predicted risk-adjusted effect of DCI on outcomes and inflation-adjusted hospital cost. RESULTS: A total of 4522 (26.2%) patients came from severely distressed communities (top quartile). These patients had higher rates of medical comorbidities, transfer from outside hospital, emergency status, and higher ACS NSQIP predicted risk scores (all P < 0.05). In addition, these patients had greater resource utilization, increased postoperative complications, and higher short- and long-term mortality (all P < 0.05). Risk-adjustment with multivariate regression demonstrated that DCI independently predicts postoperative complications (odds ratio 1.1, P = 0.01) even after accounting for ACS NSQIP predicted risk score. Furthermore, DCI independently predicted inflation-adjusted cost (+$978/quartile, P < 0.0001) after risk adjustment. CONCLUSIONS: The DCI, an established metric for socioeconomic distress, improves ACS NSQIP risk-adjustment to predict outcomes and hospital cost. These findings highlight the impact of socioeconomic status on surgical outcomes and should be integrated into ACS NSQIP risk models.

BACKGROUND: As robotic surgery becomes more ubiquitous, determining clinical benefit is necessary to justify the cost and time investment required to become proficient. We hypothesized that robotic cholecystectomy would be associated with improved clinical outcomes but also increased cost as compared with standard laparoscopic cholecystectomy. MATERIALS AND METHODS: All patients undergoing robotic or laparoscopic cholecystectomy at a single academic hospital between 2007 and 2017 were identified using an institutional clinical data repository. Patients were stratified by operative approach (robotic versus laparoscopic) for comparison and propensity score matched 1:10 based on relevant comorbidities and demographics. Categorical variables were analyzed by the χ2 test and continuous variables using the Mann-Whitney U test. RESULTS: A total of 3,255 patients underwent cholecystectomy during the study period. We observed no differences in demographics or body mass index, but greater rates of diabetes mellitus, hypertension, and gastroesophageal reflux disease were present in the laparoscopic group. After matching (n = 106 robotic, n = 1,060 laparoscopic), there were no differences in preoperative comorbidities. Patients who underwent robotic cholecystectomy had lesser durations of stay (robotic: 0.1 ± 0.7 versus laparoscopic: 0.8 ± 1.9, P < .0001) and lesser 90-day readmission rates (robotic: 0% [0], laparoscopic: 4.1% [43], P = 0.035); however, both operative and hospital costs were greater compared with laparoscopic cholecystectomy. CONCLUSION: Robotic cholecystectomy is associated with lesser duration of stay and lesser readmission rate within 90 days of the index operation, but also greater operative duration and hospital cost compared with laparoscopic cholecystectomy. Hospitals and surgeons need to consider the improved clinical outcomes but also the monetary and time investment required before pursuing robotic cholecystectomy.

OBJECTIVES: Although low socioeconomic status has been associated with increased risk of complications after cardiac surgery, analyses have typically focused on insurance status, race, or median income. We sought to determine if the Distressed Communities Index, a composite socioeconomic metric, could predict operative mortality after coronary artery bypass grafting. METHODS: All patients who underwent isolated coronary artery bypass grafting (2011-2018) in the National Society of Thoracic Surgeons adult cardiac surgery database were analyzed. Clinical data were paired with the Distressed Communities Index, which accounts for unemployment, education level, poverty rate, median income, business growth, and housing vacancies by ZIP code. Developed by the Economic Innovation Group, Distressed Communities Index scores range from 0 (no distress) to 100 (severe distress). A distressed community was defined as one having a Distressed Communities Index of 75 or greater for univariate analyses. RESULTS: Of the 575,900 patients undergoing coronary artery bypass grafting with a Distressed Communities Index score, the median age was 65 years. The operative mortality rate was 2.0%, and the composite morbidity or mortality rate was 11.5%. Distressed communities were associated with increased Society of Thoracic Surgeons predicted risk of mortality (1.97% vs 1.85%, P < .0001) and risk of composite morbidity or mortality (12.8% vs 11.7%, P < .0001). After adjusting for Society of Thoracic Surgeons risk model, the Distressed Communities Index remained significantly associated with mortality (odds ratio, 1.12; P < .0001) and composite morbidity and mortality (odds ratio, 1.03; P = .002). CONCLUSIONS: Patients from distressed communities are at increased risk for adverse events and death after coronary artery bypass grafting. The Distressed Communities Index is a useful, holistic measure of socioeconomic status that may help identify high-risk patients for quality improvement and should be considered when building risk models or comparing hospitals.

OBJECTIVE: To determine trends in National Institutes of Health (NIH) funding for cardiac surgeons, hypothesizing they are at a disadvantage in obtaining funding owing to intensive clinical demands. METHODS: Cardiac surgeons (adult/congenital) currently at the top 141 NIH-funded institutions were identified using institutional websites. The NIH funding history for each cardiac surgeon was queried using the NIH Research Portfolio Online Reporting Tools Expenditures and Results (RePORTER). Total grant funding, publications, and type was collected. Academic rank, secondary degrees, and fellowship information was collected from faculty pages. Grant productivity was calculated using a validated grant impact metric. RESULTS: A total of 818 academic cardiac surgeons were identified, of whom 144 obtained 293 NIH grants totaling $458 million and resulting in 6694 publications. We identified strong associations between an institution's overall NIH funding rank and the number of cardiac surgeons, NIH grants to cardiac surgeons, and amount of NIH funding to cardiac surgeons (P < .0001 for all). The majority of NIH funding to cardiac surgeons is concentrated in the top quartile of institutions. Cardiac surgeons had a high conversion rates from K awards (mentored development awards) to R01s (6 of 14; 42.9%). Finally, we demonstrate that the rate of all NIH grants awarded to cardiac surgeons has increased, driven primarily by P and U (collaborative project) grants. CONCLUSIONS: NIH-funded cardiac surgical research has had a significant impact over the last 3 decades. Aspiring cardiac surgeon-scientists may be more successful at top quartile institutions owing to better infrastructure and mentorship.

BACKGROUND: Socioeconomic status affects surgical outcomes, however these factors are not included in clinical quality improvement data and risk models. We performed a prospective registry analysis to determine if the Distressed Communities Index (DCI), a composite socioeconomic ranking by zip code, could predict risk-adjusted surgical outcomes and resource utilisation. METHODS: All patients undergoing surgery (n=44,451) in a regional quality improvement database (American College of Surgeons-National Surgical Quality Improvement Program ACS-NSQIP) were paired with DCI, ranging from 0-100 (low to high distress) and accounting for unemployment, education level, poverty rate, median income, business growth and housing vacancies. The top quartile of distress was compared to the remainder of the cohort and a mixed effects modeling evaluated ACS-NSQIP risk-adjusted association between DCI and the primary outcomes of surgical complications and resource utilisation. RESULTS: A total of 9369 (21.1%) patients came from severely distressed communities (DCI >75), who had higher rates of most medical comorbidities as well as transfer status (8.4% vs 4.8%, p<0.0001) resulting in higher ACS-NSQIP predicted risk of any complication (8.0% vs 7.1%, p<0.0001). Patients from severely distressed communities had increased 30-day mortality (1.8% vs 1.4%, p=0.01), postoperative complications (9.8% vs 8.5%, p<0.0001), hospital readmission (7.7 vs 6.8, p<0.0001) and resource utilisation. DCI was independently associated with postoperative complications (OR 1.07, 95% CI 1.04 to 1.10, p<0.0001) as well as resource utilisation after adjusting for ACS-NSQIP predicted risk CONCLUSION: Increasing Distressed Communities Index is associated with increased postoperative complications and resource utilisation even after ACS-NSQIP risk adjustment. These findings demonstrate a disparity in surgical outcomes based on community level socioeconomic factors, highlighting the continued need for public health innovation and policy initiatives.

OBJECTIVE: Several studies have demonstrated that socioeconomic factors may affect surgical outcomes. Analyses in vascular surgery have been limited by the availability of individual or community-level socioeconomic data. We sought to determine whether the Distressed Communities Index (DCI), a composite socioeconomic ranking by ZIP code, could predict short- and long-term outcomes for patients with peripheral artery disease. METHODS: All Virginia Quality Initiative patients (n = 2578) undergoing infrainguinal bypass (2011-2017) within a region of 17 centers were assigned a composite DCI score. The score was developed by the Economic Innovation Group and is normally distributed from 0 (no distress) to 100 (severe distress) based on measures of community unemployment, education level, poverty rate, median income, business growth, and housing vacancies. Severely distressed communities were defined as the top quartile DCI (>75). Hierarchical regression assessed short-term outcomes, and time-to-event analyses assessed long-term results. RESULTS: Infrainguinal bypass patients in this study came from disproportionately distressed communities, with 29% of patients living within the highest distress DCI quartile (P < .0001), with high variability by hospital (DCI range, 12-67). These patients from severely distressed areas were younger, more likely to smoke, and disproportionately African American and had higher rates of medical comorbidities (all P < .05). Whereas patients from severely distressed communities had an equivalent rate of 30-day major adverse cardiac and cerebrovascular events (5% vs 4%; P = .86), they had increased rates of major adverse limb events (MALEs) at 13% vs 10% (P = .03). This trend persisted in the long term, with higher 1-year estimates of MALEs (21% vs 17%; P = .01) as well as the components of amputation (17% vs 12%; P = .006) and thrombectomy (11% vs 6%; P = .002). Patients with high socioeconomic distress also had higher rates of occlusion (17% vs 11%; P = .003). CONCLUSIONS: In this study, patients from severely distressed communities were found to have increased rates of MALEs, an association that persisted long term. Mitigating risk associated with socioeconomic determinants of health has the potential to improve outcomes for patients with peripheral artery disease.

BACKGROUND: Surgical outcomes are affected by socioeconomic status, yet these factors are poorly accounted for in clinical databases. We sought to determine if the Distressed Communities Index (DCI), a composite ranking by zip code that quantifies socioeconomic risk, was associated with long-term survival after bariatric surgery. METHODS: All patients undergoing Roux-en-Y gastric bypass (1985-2004) at a single institution were paired with DCI. Scores range from 0 (no distress) to 100 (severe distress) and account for unemployment, education, poverty, median income, housing vacancies, job growth, and business establishment growth. Distressed communities, defined as DCI ≥75, were compared with all other patients. Regression modeling was used to evaluate the effect of DCI on 10-year bariatric outcomes, whereas Cox Proportional Hazards and Kaplan-Meier analysis examined long-term survival. RESULTS: Gastric bypass patients (n = 681) come from more distressed communities compared with the general public (DCI 60.5 ± 23.8 versus 50 ± 10; P < 0.0001). A total of 221 (32.3%) patients came from distressed communities (DCI ≥75). These patients had similar preoperative characteristics, including BMI (51.5 versus 51.7 kg/m2; P = 0.63). Socioeconomic status did not affect 10-year bariatric outcomes, including percent reduction in excess body mass index (57% versus 58%; P = 0.93). However, patients from distressed communities had decreased risk-adjusted long-term survival (hazard ratio, 1.38; P = 0.043). CONCLUSIONS: Patients with low socioeconomic status, as determined by the DCI, have equivalent outcomes after bariatric surgery despite worse long-term survival. Future quality improvement efforts should focus on these persistent disparities in health care.

BACKGROUND: Sternal wound infections (SWIs) can be a devastating long-term complication with significant morbidity and health care cost. The purpose of this analysis was to evaluate the cost-effectiveness of negative pressure incision management systems (NPIMS) in cardiac surgery. MATERIALS AND METHODS: All cardiac surgery cases at an academic hospital with risk scores available (2009-2017) were extracted from an institutional database (n = 4455). Patients were stratified by utilization of NPIMS, and high risk was defined as above the median. Costs included infection-related readmissions and were adjusted for inflation. Multivariable regression models assessed the risk-adjusted cost of SWI and efficacy of NPIMS use. Cost-effectiveness was modeled using TreeAge Pro using institutional results. RESULTS: The rate of deep SWI was 0.9% with an estimated cost of $111,175 (P < 0.0001). The rate of superficial SWI was 0.8% at a cost of $7981 (P = 0.08). Risk-adjusted NPIMS use was not significantly associated with reduced SWI (OR 1.2, P = 0.62) and thus not cost-effective. However, in the high-risk cohort with an OR 0.84 (P = 0.72) and SWI rate of 2.3%, NPIMS use cost $205 per patient with an incremental cost-effectiveness ratio of $179,092. Therefore, NPIMS is estimated to be cost-effective with a deep SWI rate over 1.3% or improved efficacy (OR < 0.83). CONCLUSIONS: SWIs are extremely expensive complications with estimates of $111,175 for deep yet only $7981 for superficial. Although NPIMS was not cost-effective for SWI prevention as currently utilized, a protocol for use on patients with a higher risk of sternal infection could be cost-effective.

BACKGROUND: Today's declining federal budget for scientific research is making it consistently more difficult to become federally funded. We hypothesized that even in this difficult era, surgeon-scientists have remained among the most productive and impactful researchers in lung transplantation. METHODS: Grants awarded by the NIH for the study of lung transplantation between 1985 and 2015 were identified by searching NIH RePORTER for 5 lung transplantation research areas. A grant impact metric was calculated for each grant by dividing the sum of impact factors for all associated manuscripts by the total funding for that grant. We used nonparametric univariate analysis to compare grant impact metrics by department. RESULTS: We identified 109 lung transplantation grants, totaling approximately $300 million, resulting in 2304 papers published in 421 different journals. Surgery has the third highest median grant impact metric (4.2 per $100,000). The department of surgery had a higher median grant impact metric compared to private companies (P <.0001). There was no statistical difference in the grant impact metric compared to all other medical specialties, individual departments with multiple grants, or all basic science departments (all P >.05). CONCLUSIONS: Surgeon-scientists in the field of lung transplantation have received fewer grants and less total funding compared to other researchers but have maintained an equally high level of productivity and impact. The dual-threat academic surgeon-scientist is an important asset to the research community and should continue to be supported by the NIH.

BACKGROUND: Increased utilization of donation after circulatory death (DCD) lungs may help alleviate the supply/demand mismatch between available donor organs and lung transplant candidates. Using an established porcine DCD model, we sought to determine the effect of increasing warm ischemia time (WIT) after circulatory arrest on lung function during ex vivo lung perfusion (EVLP). METHODS: Porcine donors (n = 15) underwent hypoxic cardiac arrest, followed by 60, 90, or 120 minutes of WIT before procurement and 4 hours of normothermic EVLP. Oxygenation, pulmonary artery pressure, airway pressure, and compliance were measured hourly. Lung injury scores were assessed histologically after 4 hours of EVLP. RESULTS: After EVLP, all 3 groups met all the criteria for transplantation, except for 90-minute WIT lungs, which had a mean pulmonary artery pressure increase greater than 15%. There were no significant differences between groups as assessed by final oxygenation capacity, as well as changes in pulmonary artery pressure, airway pressure, or lung compliance. Histologic lung injury scores as well as lung wet-to-dry weight ratios did not significantly differ between groups. CONCLUSIONS: These results suggest that longer WIT alone (up to 120 minutes) does not predict worse lung function at the conclusion of EVLP. Expanding acceptable WIT after circulatory death may eventually allow for increased utilization of DCD lungs in procurement protocols.
RESUMO
BACKGROUND: Postoperative atrial fibrillation (POAF) is a known risk factor for morbidity and mortality after cardiac surgery but has not been investigated in the left ventricular assist device (LVAD) population. We hypothesize that POAF will increase morbidity and resource utilization after LVAD placement. METHODS: Records were extracted for all patients in a regional database who underwent continuous-flow LVAD placement (n = 1064, 2009-2017). Patients without a history of atrial fibrillation (n = 689) were stratified by POAF for univariate analysis. Multivariable regression models calculated the risk-adjusted association of arrhythmias on outcomes and resource utilization. RESULTS: The incidence of new-onset POAF was 17.6%, and patients who developed POAF were older and more likely to have moderate/severe mitral regurgitation, a history of stroke, and concomitant tricuspid surgery. After risk adjustment, POAF was not associated with operative mortality or stroke but was associated with major morbidity (odds ratio [OR] 2.5 P = .0004), prolonged ventilation (OR 2.7, P < .0001), unplanned right ventricular assist device (OR 2.9, P = .01), and a trend toward renal failure (OR 2.0, P = .06). In addition, POAF was associated with greater risk-adjusted resource utilization, including discharge to a facility (OR 2.2, P = .007), an additional 4.9 postoperative days (P = .02), and 88 hours in the intensive care unit (P = .01). CONCLUSIONS: POAF was associated with increased major morbidity, possibly from worsening right heart failure leading to increased renal failure and unplanned right ventricular assist device placement. This led to patients with POAF having longer intensive care unit and hospital stays and more frequent discharges to a facility.

BACKGROUND: Obtaining National Institutes of Health (NIH) funding over the last 10 years has become increasingly difficult due to a decrease in the number of research grants funded and an increase in the number of NIH applications. STUDY DESIGN: National Institutes of Health funding amounts and success rates were compared for all disciplines using data from NIH, Federation of American Societies for Experimental Biology (FASEB), and Blue Ridge Medical Institute. Next, all NIH grants (2006 to 2016) with surgeons as principal investigators were identified using the National Institutes of Health Research Portfolio Online Reporting Tools Expenditures and Results (NIH RePORTER), and a grant impact score was calculated for each grant based on the publication's impact factor per funding amount. Linear regression and one-way ANOVA were used for analysis. RESULTS: The number of NIH grant applications has increased by 18.7% (p = 0.0009), while the numbers of funded grants (p < 0.0001) and R01s (p < 0.0001) across the NIH have decreased by 6.7% and 17.0%, respectively. The mean success rate of funded grants with surgeons as principal investigators (16.4%) has been significantly lower than the mean NIH funding rate (19.2%) (p = 0.011). Despite receiving only 831 R01s during this time period, surgeon scientists were highly productive, with an average grant impact score of 4.9 per $100,000, which increased over the last 10 years (0.15 ± 0.05/year, p = 0.02). Additionally, the rate of conversion of surgeon scientist-mentored K awards to R01s from 2007 to 2012 was 46%. CONCLUSIONS: Despite declining funding over the last 10 years, surgeon scientists have demonstrated increasing productivity as measured by impactful publications and higher success rates in converting early investigator awards to R01s.

BACKGROUND: The Ruth L. Kirschstein Institutional National Research Service Award (T32) provides institutions with financial support to prepare trainees for careers in academic medicine. In 1990, the Cardiac Surgery Branch of the National Heart, Lung and Blood Institute (NHLBI) was replaced by T32 training grants, which became crucial sources of funding for cardiothoracic (CT) surgical research. We hypothesized that T32 grants would be valuable for CT surgery training and yield significant publications and subsequent funding. METHODS: Data on all trainees (past and present) supported by CT T32 grants at two institutions were obtained (T32), along with information on trainees from two similarly sized programs without CT T32 funding (Non-T32). Data collected were publicly available and included publications, funding, degrees, fellowships, and academic rank. Non-surgery residents and residents who did not pursue CT surgery were excluded. RESULTS: Out of 76 T32 trainees and 294 Non-T32 trainees, data on 62 current trainees or current CT surgeons (T32: 42 vs Control: 20) were included. Trainees who were supported by a CT T32 grant were more likely to pursue CT surgery after residency (T32: 40% [30/76] vs Non-T32: 7% [20/294], P < .0001), publish manuscripts during residency years (P < .0001), obtain subsequent NIH funding (T32: 33% [7/21] vs Non-T32: 5% [1/20], P = .02), and pursue advanced fellowships (T32: 41% [9/22] vs Non-T32: 10% [2/20], P = .02). CONCLUSIONS: T32 training grants supporting CT surgery research are vital to develop academic surgeons. These results support continued funding by the NHLBI to effectively develop and train the next generation of academic CT surgeons.

BACKGROUND: Bariatric surgery leads to dramatic weight loss and improved overall health, which may affect insurance status for certain patients. Traditional Medicaid provides coverage for children, pregnant women, and disabled adults, while expanded Medicaid provides insurance coverage to all adults with incomes up to 138% of the federal poverty level. We hypothesized that successful bariatric surgery would lead to improved health status but an unintended loss of Medicaid coverage. METHODS: All patients who underwent bariatric surgery at a single institution in a non-expansion state from 1985 through 2015 were identified using a prospectively collected database. Univariate and multivariate analyses were used to identify differences in patients who lost Medicaid coverage after bariatric surgery. RESULTS: Over the 30-year study period, 3487 patients underwent bariatric surgery, with 373 (10.7%) having Medicaid coverage at the time of surgery. This cohort of patients had a median age of 37 years and a preoperative Body Mass Index (BMI) of 54 kg/m2. At one-year follow-up, 155 (41.6%) patients lost Medicaid coverage, of which 76 (49.0%) had no coverage. The preoperative prevalence of diabetes (32.3 vs. 44.0%, p = 0.02), age (36 vs. 38 years, p = 0.01), and BMI (53 vs. 55 kg/m2, p = 0.04) were significantly lower in patients who no longer qualified for Medicaid after bariatric surgery. Multivariate regression demonstrated that for every 10 point increase in BMI (OR 0.755, p = 0.01), a patient was 25% less likely to lose their coverage at one year. CONCLUSIONS: Successful surgery in a state not expanding Medicaid resulted in over 40% of patients losing Medicaid coverage postoperatively, with half of those patients returning for follow-up with no insurance coverage at all. This barrier to care has major implications in patients undergoing bariatric surgery, which requires life-long follow-up and nutrition screening.
