The impact of hospital size on national trends and outcomes in isolated open proximal aortic surgery.

OBJECTIVE: To determine the impact of hospital size on national trend estimates of isolated open proximal aortic surgery for benchmarking hospital performance. METHODS: Patients age >18 years who underwent isolated open proximal aortic surgery for aneurysm and dissection from 2002 to 2014 were identified using the National Inpatient Sample. Concomitant valvular, vessel revascularization, re-do procedures, endovascular, and surgery for descending and thoracoabdominal aorta were excluded. Discharges were stratified by hospital size and analyzed using trend, multivariable regression, propensity-score matching analysis. RESULTS: Over a 13-year period, 53,657 isolated open proximal aortic operations were performed nationally. Although the total number of operations/year increased (∼2.9%/year increase) and overall in-hospital mortality decreased (∼4%/year; both P < .001 for trend), these did not differ by hospital size (P > .05). Large hospitals treated more sicker and older patients but had shorter length of stay and lower hospital costs (both P < .001). Even after propensity-score matching, large hospital continued to demonstrate superior in-hospital outcomes, although only statistically for major in-hospital cardiac complications compared with non-large hospitals. In our subgroup analysis of dissection versus non-dissection cohort, in-hospital mortality trends decreased only in the non-dissection cohort (P < .01) versus dissection cohort (P = .39), driven primarily by the impact of large hospitals (P < .01). CONCLUSIONS: This study demonstrates increasing volume and improving outcomes of isolated open proximal aortic surgeries nationally over the last decade regardless of hospital bed size. Moreover, the resource allocation of sicker patients to larger hospital resulted shorter length of stay and hospital costs, while maintaining similar operative mortality to small- and medium-sized hospitals.

Longitudinal analysis of National Institutes of Health funding for academic thoracic surgeons.

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.

Trend of lung cancer surgery, hospital selection, and survival between 2005 and 2016 in South Korea.

BACKGROUND: Studies on the clinical implication of hospital selection for patients with lung cancer are few. Therefore, this study aimed to analyze 2005-2016 data from the Korean national database to assess annual trends of lung cancer surgery and clinical outcomes according to hospital selection. METHODS: Data of 212 554 patients with lung cancer who underwent upfront surgery were screened. Trends according to sex, age, residence, and income were examined. Descriptive statistics were performed, and ptrend values were estimated. The association between survival and hospital selection was assessed using the log-rank test. A multivariate Cox regression analysis was also performed. RESULTS: A total of 49 021 patients were included in this study. Surgery was prevalent among men, patients aged 61-75 years, capital area residents, and high-income patients. However, with the increasing rate of surgery among women, patients aged ≥76 years, city residents, and middle-income patients, the current distribution of lung cancer surgery could change. The rate of lobectomy among these groups increased. All patients, except those in capital areas, preferred a hospital outside their area of residence (HOR); the number of patients with this tendency also increased. However, this trend was not observed among low-income patients and those aged ≥76 years. There were significant differences in survival according to hospital selection. CONCLUSIONS: The trend of lung cancer surgery is changing. The current medical system is effective in providing lobectomy for patients including women, aged ≥76 years, city residents, and middle-income. Increasing tendency to choose an HOR requires further study.

Gender representation among leadership at national and regional cardiothoracic surgery organizational annual meetings.

BACKGROUND: Increased attention has been dedicated to gender inequity at scientific meetings. This study evaluated the gender distribution of session leaders at cardiothoracic surgery national and regional meetings. METHODS: This is a descriptive study of the gender of peer-selected session leaders at 4 cardiothoracic surgery organizations' annual meetings from 2015 to 2019. Session leaders included moderators, panelists, and invited discussants. Data from publicly available programs were used to generate a list of session leaders and organization leaders. The primary outcome measure was the proportion of female session leaders at annual meetings. Descriptive analyses were performed, including the Cochran-Armitage trend test for linear trends of proportions. RESULTS: A total of 679 sessions over 20 meetings were examined. Of the 3662 session leaders, 480 (13.1%) were women. The proportion of total female session leaders trended positively over time from 9.6% (56 of 581) in 2015 to 15.9% (169 of 1060) in 2019 (P = .001). Among specialty topic sessions, female session leaders were distributed as follows: adult cardiac, 6.9% (81 of 1172); congenital cardiac, 10.8% (47 of 437); and thoracic, 23.2% (155 of 668). The proportion of female session leaders trended significantly only for thoracic sessions (20.6% [21 of 102] in 2015 to 29.2% [58 of 199] in 2019; P = .02). More than one-half of the sessions (57.4%; 390 of 679) featured all-male session leadership. CONCLUSIONS: Women remain underrepresented in leadership roles at cardiothoracic surgery organizational meetings. This may deter female applicants and has implications for female surgeons' career trajectories; therefore, attention must be given to the potential for unconscious bias in leadership in cardiothoracic surgery.

Lung Ultrasound Findings in the Postanesthesia Care Unit Are Associated With Outcome After Major Surgery: A Prospective Observational Study in a High-Risk Cohort.

BACKGROUND: Postoperative pulmonary complications are associated with increased morbidity. Identifying patients at higher risk for such complications may allow preemptive treatment. METHODS: Patients with an American Society of Anesthesiologists (ASA) score >1 and who were scheduled for major surgery of >2 hours were enrolled in a single-center prospective study. After extubation, lung ultrasound was performed after a median time of 60 minutes by 2 certified anesthesiologists in the postanesthesia care unit after a standardized tracheal extubation. Postoperative pulmonary complications occurring within 8 postoperative days were recorded. The association between lung ultrasound findings and postoperative pulmonary complications was analyzed using logistic regression models. RESULTS: Among the 327 patients included, 69 (19%) developed postoperative pulmonary complications. The lung ultrasound score was higher in the patients who developed postoperative pulmonary complications (12 [7-18] vs 8 [4-12]; P < .001). The odds ratio for pulmonary complications in patients who had a pleural effusion detected by lung ultrasound was 3.7 (95% confidence interval, 1.2-11.7). The hospital death rate was also higher in patients with pleural effusions (22% vs 1.3%; P < .001). Patients with pulmonary consolidations on lung ultrasound had a higher risk of postoperative mechanical ventilation (17% vs 5.1%; P = .001). In all patients, the area under the curve for predicting postoperative pulmonary complications was 0.64 (95% confidence interval, 0.57-0.71). CONCLUSIONS: When lung ultrasound is performed precociously <2 hours after extubation, detection of immediate postoperative alveolar consolidation and pleural effusion by lung ultrasound is associated with postoperative pulmonary complications and morbi-mortality. Further study is needed to determine the effect of ultrasound-guided intervention for patients at high risk of postoperative pulmonary complications.

The Thoracic Surgery Residents Association: Past contributions, current efforts, and future directions.

OBJECTIVE: The Thoracic Surgery Residents Association (TSRA) is a resident-led organization established in 1997 under the guidance of the Thoracic Surgery Directors Association to represent the interests and educational needs of cardiothoracic surgery residents. We aim to describe the past contributions, current efforts, and future directions of the TSRA within a conceptual framework of the TSRA mission. METHODS: Primary review of educational resources was performed to report goals and content of past contributions. TSRA Executive Committee input was used to describe current resources and activities, as well as the future goals of the TSRA. Podcast analytics were performed to report national and global usage. RESULTS: Since 2011, the TSRA has published 3 review textbooks, 5 reference guides, 3 test-preparation textbooks, 1 supplementary publication, and 1 multiple-choice question bank and mobile application, all written and developed by cardiothoracic surgery trainees. In total 108 podcasts have been recorded by mentored trainees, with more than 175,000 unique listens. Most recently, the TSRA has begun facilitating trainee submissions to Young Surgeon's Notes, fostered a trainee mentorship program, developed the monthly TSRA Newsletter, and established a wide-reaching presence on Facebook, Twitter, and Instagram to help disseminate educational resources and opportunities for trainees. CONCLUSIONS: The TSRA continues to be the leading cardiothoracic surgery resident organization in North America, providing educational resources and networking opportunities for all trainees. Future directions include development of an integrated disease-based resource and continued collaboration within and beyond our specialty to enhance the educational opportunities and career development of cardiothoracic trainees.

Artificial intelligence in cardiothoracic surgery.

The tremendous and rapid technological advances that humans have achieved in the last decade have definitely impacted how surgical tasks are performed in the operating room (OR). As a high-tech work environment, the contemporary OR has incorporated novel computational systems into the clinical workflow, aiming to optimize processes and support the surgical team. Artificial intelligence (AI) is increasingly important for surgical decision making to help address diverse sources of information, such as patient risk factors, anatomy, disease natural history, patient values and cost, and assist surgeons and patients to make better predictions regarding the consequences of surgical decisions. In this review, we discuss the current initiatives that are using AI in cardiothoracic surgery and surgical care in general. We also address the future of AI and how high-tech ORs will leverage human-machine teaming to optimize performance and enhance patient safety.

The impact of coronavirus disease 2019 on the practice of thoracic oncology surgery: a survey of members of the European Society of Thoracic Surgeons (ESTS).

OBJECTIVES: There is widespread acknowledgement that coronavirus disease 2019 (COVID-19) has disrupted surgical services. The European Society of Thoracic Surgeons (ESTS) sent out a survey to assess what impact the COVID-19 pandemic has had on the practice of thoracic oncology surgery. METHODS: All ESTS members were invited (13-20 April 2020) to complete an online questionnaire of 26 questions, designed by the ESTS learning affairs committee. RESULTS: The response rate was 23.0% and the completeness rate was 91.2%. The number of treated COVID-positive cases per hospital varied from fewer than 20 cases (30.6%) to more than 200 cases (22.7%) per hospital. Most hospitals (89.1%) postponed surgical procedures. All hospitals performed patient screening with a nasopharyngeal swab, but only 6.7% routinely tested health care workers. A total of 20% of respondents reported that multidisciplinary meetings were completely cancelled and 66%, that multidisciplinary decisions were not different from normal practice. Trends were recognized in prioritizing surgical patients based on age (younger than 70), type of surgery (lobectomy or less), size of tumour (T1-2) and lymph node involvement (N1). Sixty-three percent of respondents reported that surgeons were involved in daily care of COVID-19-positive patients. Fifty-three percent mentioned that full personal protective equipment was available to them when treating a COVID-19-positive patient. CONCLUSIONS: The COVID-19 pandemic has created issues for the safety of health care workers, and surgeons have been forced to change their routine practice. However, there was no consensus about surgical priorities in lung cancer patients, demonstrating the need for the production of specific guidelines.

Current trends in thoracic surgery.

Thoracic surgery has evolved drastically in recent years. Although thoracic surgeons mainly deal with tumorous lesion in the lungs, mediastinum, and pleura, they also perform lung transplantation surgery in patients with end-stage lung disease. Herein, we introduce various major current topics in thoracic surgery. Minimally invasive surgical procedures include robot-assisted thoracic surgery and uniportal video-assisted thoracic surgery. Novel techniques for sublobar resection include virtual-assisted lung mapping, image-guided video-assisted thoracic surgery, and segmentectomy using indocyanine green. Three-dimensional (3D) computed tomography (CT) simulation consists of surgeon-friendly 3D-CT image analysis systems and new-generation, dynamic 3D-CT imaging systems. Updates in cadaveric lung transplantation include use of marginal donors, including donation after circulatory death, and ex vivo lung perfusion for such donors. Topics in living donor lobar lung transplantation include size matching, donor issues, and new surgical techniques. During routine clinical practice, thoracic surgeons encounter various pivotal topics related to thoracic surgery, which are described in this report.

Microalbuminuria assessment after thoracic surgery: Early identification of complication risks.

INTRODUCTION: Microalbuminuria (MA) is considered a reflection of systemic capillary leak and an early marker of acute stress reaction to the surgical insult, proportional to the severity of the initiating condition and predictive of the individual response to surgical stress. OBJECTIVES: We conducted a prospective study to assess for the variation of MA within 4 days after thoracic surgery. We correlated observed MA levels with both their respective PaO2 /FiO2 respiratory ratio and the onset of postoperative complications. METHODS: This single-centre study enrolled 255 consecutive patients having an American Society of Anaesthesiologists (ASA) score ≤ 3. The mean age was 62 years with 67% male. All patients were scheduled for elective pulmonary resection. MA was measured in urine samples as the albumin-to-creatinine ratio (A/C), prior to, at and after extubation up to 96 hours. PaO2 /FiO2 was measured at extubation and on the first postoperative day. RESULTS: Overall, preoperative A/C levels resulted normal, with a significant average increase at extubation which peaked 6 hours later (P < 0.001). Larger postoperative A/C increases were observed in patients who developed postoperative complications, compared to those without these complications (P < 0.019). Moreover, patients undergoing major open pulmonary resections had larger postoperative A/C increases, compared to those undergoing minor video-assisted thoracic surgery resections (P < 0.006). At the time of extubation, A/C was inversely related to the PaO2 /FiO2 ratio (r = -0.25; P = 0.038). Peak A/C > 61 mg/g (P = 0.0003) was associated with postoperative cardio-pulmonary complications (OR 3.85; P = 0.003). CONCLUSION: Within 6 hours after extubation, MA assessment may be a rapid and relatively inexpensive method for better predicting perioperative risk in an ASA score ≤ 3 population.

Scoliosis Progression After the Nuss Procedure for Pectus Excavatum: A Case Report.

INTRODUCTION: Pectus excavatum and scoliosis are associated conditions with a high rate of coincidence. However, there are no reports to guide surgeons on the management of adolescents with moderate scoliosis and pectus excavatum, because there are conflicting conclusions in the literature regarding how the Nuss procedure with substernal bar affects scoliosis. CASES: In 2017, we encountered two patients with moderate scoliosis treated with a spinal orthosis. After undergoing the Nuss procedure for pectus excavatum, their scoliosis acutely progressed into surgical magnitude requiring posterior instrumented spinal fusion. The first patient progressed 26° despite the pre-Nuss radiographs showing him to be Risser 4/5, while the second patient also progressed 26° from the Nuss procedure. Both patients acknowledged noncompliance with brace wear because of discomfort after the Nuss procedure. However, their progression rate still doubles the rate of reported rapid accelerators, indicating that a significant component of curve progression is directly attributed to forces on the spine from the corrective maneuver with substernal bar. CONCLUSION: The purpose of this case report is to describe the features of these two patients to help with clinical decision-making in patients with moderate scoliosis (curves >25°) who are contemplating the Nuss procedure for correction of pectus excavatum. We caution patients and providers that spinal deformity could worsen with surgical intervention of the pectus excavatum via the Nuss procedure and necessitate scoliosis surgery.

Port Strategies for Robot-Assisted Lobectomy by High-Volume Thoracic Surgeons: A Nationwide Survey.

OBJECTIVE: Robot-assisted lobectomy is the fastest growing technique for pulmonary lobectomy, but the diversity of approaches has led to apprehension about port placement among learning surgeons. The aim of this study was to survey high-volume thoracic surgeons who perform robot-assisted lobectomy to understand and consolidate common themes of port placement. METHODS: An electronic online survey was created, and the link was emailed to the 100 highest volume robotic thoracic surgeons in the United States. The survey included an interactive graphical interface, which allowed each respondent to mark the preferential robotic port placement in the chest wall for each of the 5 pulmonary lobectomies. Results were analyzed individually and in aggregate. A heat map was generated to show trends. RESULTS: One hundred surgeons were surveyed (response rate: 62%). Most (90%) respondents utilized a 4-arm approach and 79% used a completely 4-arm portal approach with CO2 insufflation. Exact locations for each robotic port were reported by 60% of the surveyed surgeons and the results varied; however, most surgeons generally used the seventh to ninth interspaces for the camera and instruments. The use of multiple different interspace levels was common. Ninety-four percent of respondents used an additional nonrobotic assistant port. CONCLUSIONS: There is not a universal port strategy for robot-assisted lobectomy. However, placement of the camera and robotic ports low in the seventh to ninth interspaces is the most common approach. There are some nuances of stapling port strategies and sequence of port placement, which are identified.

Innovations in Airway Surgery.

The management of pediatric airway stenosis has evolved considerably over time. At the outset, dilation was the mainstay of management. In the 1900s, open surgery in the form of cricoid expansion procedures or resection procedures was the primary treatment with subsequent development of the slide tracheoplasty. Now in the twenty-first century, advances in endoscopic management, balloon dilation, and stenting, along with the advent of external scaffolds and tissue replacement continue to advance pediatric airway surgery.
