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.

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.

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.

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.

Integrated Thoracic Surgery Residency: Current Status and Future Evolution.

Cardiothoracic surgery training has evolved after a fading interest in the traditional pathway. Despite recent stagnation, the integrated pathway will likely further grow in popularity and acceptance.

Incorporating Innovation and New Technology Into Cardiothoracic Surgery.

The appropriate implementation of new technology, root cause analysis of "imperfect" outcomes, and the continuous reappraisal of postgraduate training are needed to improve the care of tomorrow's patients. Healthcare delivery remains one of the most expensive sectors in the United States, and the application of new and expensive technology that is necessary for the advancement of this complex specialty must be aligned with providing the best care for our patients. There are a several pathways to innovation: One is partnering with industry and the other is the investigational laboratory. Innovation and the funding thereof come from both the public and private sector. Most new trials that are likely to impact cardiothoracic surgery are industry-sponsored trials to meet the requirements necessary for regulatory approval. Cost considerations are paramount when considering integration of innovative technology and treatments into a clinical cardiothoracic surgical practice. The value of any new innovation is determined by the quality divided by the cost, and lean initiatives maximize this equation. The importance and implications of conflict of interest have been a concern for physicians, particularly when new technology or procedures are incorporated into clinical practice, and full disclosures by medical professionals and others involved are essential. Our societies and associations provide a platform for presentation and peer-reviewed discussion of new procedures, innovations, and trials and provide a venue for the sharing of knowledge on the highest quality patient care through education and research.

Providing cardiothoracic services in 2035: Signs of trouble ahead.

OBJECTIVE: As the population ages, we will present the reality around being able to meet the health care needs of our population. In particular, we will present that providing cardiothoracic services in 2035 with a shortage of surgeons and an unknown caseload may be an impossibility. METHODS: By using data from the American Board of Thoracic Surgery, we estimate that in 2010, 4000 cardiothoracic surgeons performed more than 530,000 cases. Additionally, cardiothoracic residency programs train and certify on average 90 new surgeons every year. To estimate the number of cases for 2035, we consulted the Census Bureau figures for 2010 and population projections for 2035. We then estimated the expected caseload for cardiothoracic surgeons relative to heart surgery, as well as lung and esophageal surgery. We found that among 2010 cardiothoracic surgeons in the United States, they completed more than 530,000 cases. RESULTS: We project that by 2035 there will be 853,912 cases to perform, representing an increase from 2010 to 2035 of approximately 61% nationally. The cases per surgeon, per year, in 2010 averaged 135 for almost each of the 4000 surgeons. In 2035, the average caseload per surgeon will be 299 cases, representing an increase of 121% for the individual surgeon. CONCLUSIONS: We conclude that by 2035, cardiothoracic surgeons will be responsible for more than 850,000 patients requiring surgery. This represents a 61% increase in the national case load and a potential for a 121% increase for each cardiothoracic surgeon. We believe this is not feasible and a sign of trouble ahead.

Goals of surgery and assessment tools for elderly patients referred for cardiac and noncardiac surgery.

Surgery in elderly patients is associated with the risk of death, complications, functional decline and disability. Prior to surgery, therefore, an assessment of the health-related priorities, a realistic evaluation of the surgical risks, and individualized optimization of the procedural pathway to follow are mandatory.

A novel approach for the accurate prediction of thoracic surgery workforce requirements in Canada.

OBJECTIVE: To develop a microsimulation model of thoracic surgery workforce supply and demand to forecast future labor requirements. METHODS: The Canadian Community Health Survey and Canadian Census data were used to develop a microsimulation model. The demand component simulated the incidence of lung cancer; the supply component simulated the number of practicing thoracic surgeons. The full model predicted the rate of operable lung cancers per surgeon according to varying numbers of graduates per year. RESULTS: From 2011 to 2030, the Canadian national population will increase by 10 million. The lung cancer incidence rates will increase until 2030, then plateau and decline. The rate will vary by region (12.5% in Western Canada, 37.2% in Eastern Canada) and will be less pronounced in major cities (10.3%). Minor fluctuations in the yearly thoracic surgery graduation rates (range, 4-8) will dramatically affect the future number of practicing surgeons (range, 116-215). The rate of operable lung cancer varies from 35.0 to 64.9 cases per surgeon annually. Training 8 surgeons annually would maintain the current rate of operable lung cancer cases per surgeon per year (range, 32-36). However, this increased rate of training will outpace the lung cancer incidence after 2030. CONCLUSIONS: At the current rate of training, the incidence of operable lung cancer will increase until 2030 and then plateau and decline. The increase will outstrip the supply of thoracic surgeons, but the decline after 2030 will translate into an excess future supply. Minor increases in the rate of training in response to short-term needs could be problematic in the longer term. Unregulated workforce changes should, therefore, be approached with care.

The theory, practice, and future of process improvement in general thoracic surgery.

Process improvement, in its broadest sense, is the analysis of a given set of actions with the aim of elevating quality and reducing costs. The tenets of process improvement have been applied to medicine in increasing frequency for at least the last quarter century including thoracic surgery. This review outlines the theory underlying process improvement, the currently available data sources for process improvement and possible future directions of research.

Global aspects of cardiothoracic surgery with focus on developing countries.

The incidence and prevalence of cardiothoracic disease continue to increase globally, especially in emerging economies and developing countries. Cardiothoracic surgery is also growing despite limited access, availability of surgical centers, political and cost issues. The increase in atherosclerotic coronary artery disease, rheumatic heart disease, congenital heart disease, trauma, and thoracic malignancies is a more urgent problem than realized in these emerging economies and developing countries, or low- and middle-income countries. A determined focus and cooperation between the preventive and curative elements of care is warranted. This represents a paradigm shift to develop a consensus that fosters a multi-integrated disease-specific approach that includes prevention, promotion, diagnosis, treatment, and rehabilitation. In addition, the concept or acceptance of surgery as a necessary component of public health policy is critical to improving overall global healthcare.

The economic benefit of organizational restructuring of the cardiothoracic intensive care unit.

OBJECTIVES: Compare cost/benefits of organizational restructuring of the cardiac intensive care unit (CICU). DESIGN: Prospective, with a retrospective control period. SETTING: Academic medical center. PARTICIPANTS: Sixty-six CICU patients (prospective) and 57 patients who received care before restructuring (retrospective) were compared. Entrance criteria were constant for both study periods. INTERVENTIONS: The CICU was restructured from a level III ICU to a level I ICU with the initiation of a consultant CICU service. The CICU service provided an attending physician dedicated to ICU care daily. All cardiac patients admitted into the CICU received consultation by the CICU service. MEASUREMENTS AND MAIN RESULTS: The average postoperative intubation time decreased during the intervention period (61% extubated within 6 hours v 12%, p = 0.004). Pharmacy, radiology, laboratory, and ICU costs decreased 279 US dollars (p = 0.004), 196 US dollars (p = 0.003), 190 US dollars (p = 0.15), and 470 US dollars (p = 0.12), respectively. The ICU length of stay (0.28 days shorter) as well as the overall postsurgery stay (0.54 days shorter) were reduced in the intervention period (p = 0.11 and 0.10, respectively). CONCLUSIONS: The CICU service significantly reduced both total ICU-related costs ($1,173/patient) and overall costs (2,285 US dollars/patient) during the intervention period. Professional fees only reduced overall savings by 8%. These results indicate that organizational restructuring of the CICU to newer models can reduce costs associated with cardiac surgery.
