Chatbot Reliability in Managing Thoracic Surgical Clinical Scenarios.

BACKGROUND: Chatbot use in medicine is growing, and concerns have been raised regarding their accuracy. We assessed the performance of four different chatbots in managing thoracic surgical clinical scenarios. METHODS: Topic domains were identified and clinical scenarios were developed within each domain. Each scenario included three stems utilizing Key Feature methods related to diagnosis, evaluation, and treatment. Twelve scenarios were presented to ChatGPT-4, Bard, Perplexity, and Claude 2 in three separate runs. Up to 1 point was awarded for each stem, yielding a potential of 3 points per scenario. Critical failures were identified prior to scoring; if they occurred, the stem and overall scenario scores were adjusted to 0. We arbitrarily established a threshold of ≥2 points mean adjusted score per scenario as a passing grade and established a critical fail rate of ≥30% as failure to pass. RESULTS: The bot performances varied considerably within each run and their overall performance was a fail on all runs (critical mean scenario fails of 83%, 71%, and 71%). The bots trended towards "learning" from the first to the second run, but without improvement in overall raw (1.24 ± 0.47 vs 1.63 ± 0.76 vs 1.51 ± 0.60; p=0.29) and adjusted scenario scores (0.44 ± 0.54 vs 0.80 ± 0.94 vs 0.76 ± 0.81; p=0.48) after all runs. CONCLUSIONS: Chatbot performance in managing clinical scenarios was insufficient to provide reliable assistance. This is a cautionary note against reliance on the current accuracy of chatbots in complex Thoracic Surgery medical decision making.

A Rare Occurrence of Rotational Retro-Esophageal Gastric Body Herniation Through a Nissen Fundoplication.

Anti-reflux procedures have become a mainstay in managing gastroesophageal reflux disease (GERD) and hiatal hernia. Unfortunately, post-operative events such as breakdown of the wrap, downward slippage, or transdiaphragmatic herniation of an intact wrap cause these procedures to fail and create complications such as recurrent hiatal hernia and reflux dysphagia, regurgitation, and obstruction requiring revision surgery. We discuss a case of a rotational retro-esophageal herniation of the gastric body through a Nissen fundoplication presenting as obstruction, dysphagia, and regurgitation, highlighting the peculiar nature of this presentation and the ease of misdiagnosis given its rarity.

A History of Health Policy and Health Disparity.

Civil Rights legislation and court decisions influenced health care policy, which attempted to provide health care to elderly and low-income populations. Passing Medicaid and Medicare was monumental in increasing access to health insurance. The Affordable Care Act aimed to increase access to and affordability of health care to alleviate some disparities in health care. The Affordable Care Act established the National Institute of Minority and Health Disparity and Offices of Minority Health. However, disparities of access, care, morbidity, and mortality among marginalized populations persist. We in the thoracic community must leverage all means to mitigate the injustice of health disparities.

Critical Analysis of the National Emphysema Treatment Trial Results for Lung-Volume-Reduction Surgery.

The National Emphysema Treatment Trial compared medical treatment of severe pulmonary emphysema with lung-volume-reduction surgery in a multiinstitutional randomized prospective fashion. Two decades later, this trial remains one of the key sources of information we have on the treatment of advanced emphysematous lung disease. The trial demonstrated the short- and long-term effectiveness of surgical intervention as well as the need for strict patient selection and preoperative workup. Despite these findings, the key failure of the trial was an inability to convince the medical community of the value of surgical resection in the treatment of advanced emphysema.

Managing Otolaryngologic Complications in Cardiothoracic Surgery.

BACKGROUND: Cardiothoracic procedures are often lifesaving operations, and because of their complexity they are not without complications. Although major complications are often recognized and treated immediately, there are many less commonly identified complications that can and frequently should be addressed by otolaryngology colleagues during a patient's hospital course. METHODS: This comprehensive review describes otolaryngologic complications of cardiac and thoracic surgery. RESULTS: Dysphonia, dysphagia, stridor, tracheotomy hemorrhage, and pharyngeal tear are all complications of cardiothoracic procedures. Indications for treatment and treatment options are reviewed. The impact on quality of life and long-term morbidity is also discussed. CONCLUSIONS: Otolaryngologic complications are common after cardiothoracic procedures. An otolaryngologist should be asked to evaluate a patient with dysphonia, dysphagia, or stridor while the patient is an inpatient. Patients experiencing persistent or nonacute problems should be referred to otolaryngologists to discuss more long-term interventions.

Sexual Harassment and Cardiothoracic Surgery: #UsToo?

BACKGROUND: Fifty-eight percent of women in science, engineering, and medicine report being affected by sexual harassment (SH). This study sought to determine the extent of SH in cardiothoracic surgery. METHODS: The study developed a survey that was based on the Sexual Experience Questionnaire-Workplace, physician wellness, and burnout surveys. The survey was open to responses for 45 days and was disseminated through The Society of Thoracic Surgeons, Women in Thoracic Surgery, and Thoracic Surgery Residents Association listservs. A reminder email was issued at 28 days. Student t tests, Fisher exact tests, and χ2 tests were used to compare results. RESULTS: Of 790 respondents, 75% were male and 82% were attending surgeons. A total of 81% of female surgeons vs 46% of male attending surgeons experienced SH (P < .001). SH also was reported by trainees (90% female vs 32% male; P < .001). According to women, the most common offenders were supervising leaders and colleagues; for men, it was ancillary staff and colleagues. Respondents reported SH at all levels of training. A total of 75% of women surgeons vs 51% of men surgeons witnessed a colleague be subjected to SH; 89% of respondents reported the victim as female (male 2%, both 9%; P < .001). A total of 49% of female witnesses (50% of male witnesses) reported no intervention; less than 5% of respondents reported the offender to a governing board. SH was positively associated with burnout. CONCLUSIONS: SH is present in cardiothoracic surgery among faculty and trainees. Although women surgeons are more commonly affected, male surgeons also are subjected to SH. Despite witnessed events, intervention currently is limited. Policies, safeguards, and bystander training should be instituted to decrease these events.

STS, ESTS and JACS survey on surveillance practices after surgical resection of lung cancer.

OBJECTIVES: A 1995 survey of Society of Thoracic Surgeons (STS) members revealed wide variation in postresection lung cancer surveillance practices and pessimism regarding any survival benefit. We sought to compare contemporary practice patterns and attitudes among members of STS, European Society of Thoracic Surgeons (ESTS) and the Japanese Association for Chest Surgery (JACS). METHODS: A survey identical to the one conducted in 1995 was administered via mail or electronically. χ2 tests for associations were used to compare profiles of respondents and attitudes towards testing between groups. All the statistical tests were two-sided and P-values of 0.05 or less were considered statistically significant. RESULTS: A total of 2978 STS members (response rate 7.8%, n = 234), 1450 ESTS members (response rate 8.4%, n = 122) and 272 JACS (response rate 40.8%, n = 111) members were surveyed. Rate of guideline-recommended surveillance computed tomography was reported highest among ESTS respondents for stage I patients (22% ESTS, 3% STS and 6% JACS members, P < 0.001). However, both JACS and ESTS respondents reported higher rates of use of non-guidelines-recommended tests compared to STS respondents, which persisted on adjusted analyses. Regarding attitudes towards surveillance, more JACS and ESTS members either 'agree' or 'strongly agree' that routine testing for non-small-cell lung cancer recurrence results in potentially curative treatment (ESTS: 86%, STS: 70%, JACS: 90%, P < 0.001). Similarly, JACS and ESTS respondents believe that the current literature documents definitive survival benefits from routine follow-up testing (ESTS: 57%, STS: 30%, JACS: 62%, P < 0.001). CONCLUSIONS: The Japanese attitude towards surveillance is similar to that of ESTS members potentially highlighting significant differences between European and Asian surgeons compared to STS members. These differences clearly highlight the need for better prospective studies and joint recommendations to globally standardize practice.

Disparity between recent graduates' and experienced surgeons' assessment of time to operative independence.

BACKGROUND: In cardiothoracic surgery, little data exist on the transition to operative independence. We aimed to compare current perceptions of operative autonomy of junior cardiothoracic surgeons and senior colleagues who oversee transitional years. METHODS: An anonymous online survey was sent to currently practicing North American board-certified/eligible cardiothoracic surgeons to assess reported time to operative independence and comfort with cardiothoracic operations. The χ2 test, Fisher exact test, and Mann-Whitney U test were used to compare junior surgeons' self-reported experience to the junior experience as reported by the midcareer and senior surgeons with whom they practiced. Logistic regression was performed to assess factors associated with operative independence. RESULTS: Responses from 436 completed surveys were analyzed (82 juniors and 354 midcareer/seniors). Two hundred fifty-four midcareer/senior surgeons reported on the experience of 531 junior partners. Juniors reported high immediate posttraining comfort with basic cardiac cases and moderate comfort with all other categories. Time to operative independence was significantly different between juniors' self-report and midcareer/senior reports of junior partners except for complex thoracic cases. In multivariable logistic regression analysis, senior, and not midcareer, surgeon status was independently associated with junior operative independence status for cardiac cases and for basic thoracic cases. CONCLUSIONS: Most junior surgeons perceived operative independence with basic thoracic, basic cardiac, and complex cardiac operations earlier in their surgical career than that reported by senior colleagues. Objective measures of operative independence may clarify this discrepancy. This study establishes a baseline by which to compare the effects of integrated 6-year programs on operative independence. The discrepant perceptions may have implications for how training programs prepare graduates for the transition to independent practice.

The Society of Thoracic Surgeons National Database 2018 Annual Report.

The Society of Thoracic Surgeons (STS) National Database was established in 1989 as an initiative for quality improvement and patient safety among cardiothoracic surgeons. As of January 1, 2018, the STS National Database has four components, each focusing on a different area of cardiothoracic surgery-adult cardiac surgery, general thoracic surgery, and congenital heart surgery, as well as mechanical circulatory support through the STS Intermacs Database. In December 2015, The Annals of Thoracic Surgery began publishing a monthly series of scholarly articles on outcomes analysis, quality improvement, and patient safety. As part of that series, this article provides an annual summary of the status of the STS National Database as of October 2018 and provides a synopsis of related articles that appeared in The Annals of Thoracic Surgery 2018 series entitled: "Outcomes Analysis, Quality Improvement, and Patient Safety".

Advancing the Legislative Priorities of Cardiothoracic Surgeons: The Society of Thoracic Surgeons Political Action Committee.

In the late 1990s, several federal government health policy decisions threatened the viability of thoracic surgery as a specialty. To respond to such decisions, active participation in political processes was given extremely high priority by the Executive Committee of The Society of Thoracic Surgeons (STS). Creation of the STS Political Action Committee (STS-PAC) in 1997 was a part of the platform of participation. The purpose of the STS-PAC is to enhance the Society's voice and stature in health care policymaking. Although the STS-PAC receives voluntary contributions from STS members, on average, only 10% of STS members contribute to the STS-PAC. For the 2015-2016 election cycle, there were 542 contributors to the STS-PAC totaling $273,000. An annual contribution of $100 from every STS member would put the STS-PAC into the top 10 for medical PACs (whereas currently it is ranked 22nd of 28 in the group of physician and dental association PACs). Despite the relatively small dollar amount the STS-PAC directs, its strategic disbursement of these dollars has yielded impressive results. For example, the STS-PAC was able to use its influence to effectively stop the Centers for Medicare and Medicaid Services from implementing a potentially calamitous rule that would effectively end traditional global surgical payments. Other advocacy successes include providing guidance to the Centers for Medicare and Medicaid Services in developing the national coverage determination for transcatheter aortic valve replacement and structuring its complex reimbursement schedule, and ensuring that a provision was included in the bill that would give the STS National Database access to claims data. The STS-PAC is a principal component of the STS' advocacy armamentarium. Despite the many successes of the STS-PAC, with even modest contributions by more STS members, the STS-PAC could become a leading medical PAC, and would give the STS an even stronger presence and voice in Washington, DC. Clearly, contributing to the STS-PAC provides STS members the opportunity to have a voice and an impact on health policy and the care of their patients.

Surgeon Involvement in Transcatheter Aortic Valve Replacement in the United States: A 2016 Society of Thoracic Surgeons Survey.

BACKGROUND: The Society of Thoracic Surgeons (STS) surveyed cardiothoracic surgeon participants in its Adult Cardiac Surgery Database (ACSD) to learn the extent of surgeon involvement in transcatheter aortic valve replacement (TAVR) procedures. METHODS: An electronic survey was delivered to 2,594 surgeons in June 2016. When the survey closed 2 weeks later, 487 completed surveys had been submitted for a response rate of 18.8%. RESULTS: Among the 487 participants in the ACSD who responded to the survey, 410 (84.2%) reported that TAVR was performed at their institutions. Approximately three-quarters reported that they performed TAVR procedures as part of a heart team (77.5%; 313 of 404), cardiologists and cardiothoracic surgeons were jointly responsible for TAVR referrals (83.7%; 339 of 405), and TAVR programs were administered either jointly by the cardiology and cardiac surgery departments or exclusively by the cardiac surgery department (73.3%; 297 of 405). A majority were involved in the pre-, intra-, and postoperative care of patients undergoing TAVR, with 91.4% (370 of 405) reporting participation in multidisciplinary meetings, at least 50% regularly performing technical aspects in 10 of 11 conduct of operation categories, and 86.6% (266 of 307) caring for patients undergoing TAVR after the procedure. CONCLUSIONS: Cardiac surgeons in the United States are active participants in the management of patients with aortic stenosis as part of the heart team. The STS survey found that not only were they actively involved in the treatment decision-making process but they also played a significant role in the valve procedure, including deployment and postprocedural care. The heart team model continues to evolve and should be expanded into other areas of structural heart disease.

How Is Physician Work Valued?

Strategies to value physician work continue to evolve. The Society of Thoracic Surgeons and The Society of Thoracic Surgeons National Database have an increasingly important role in this evolution. An understanding of the Current Procedural Terminology (CPT) system (American Medical Association [AMA], Chicago, IL) and the Relative Value Scale Update Committee (RUC) is necessary to comprehend how physician work is valued. In 1965, with the dawn of increasingly complex medical care, immense innovation, and the rollout of Medicare, the need for a common language describing medical services and procedures was recognized as being of critical importance. In 1966, the AMA, in cooperation with multiple major medical specialty societies, developed the CPT system, which is a coding system for the description of medical procedures and medical services. The RUC was created by the AMA in response to the passage of the Omnibus Budget Reconciliation Act of 1989, legislation of the United States of America Federal government that mandated that the Centers for Medicare & Medicaid Services adopt a relative value methodology for Medicare physician payment. The role of the RUC is to develop relative value recommendations for the Centers for Medicare & Medicaid Services. These recommendations include relative value recommendations for new procedures or services and also updates to relative value recommendations for previously valued procedures or services. These recommendations pertain to all physician work delivered to Medicare beneficiaries and propose relative values for all physician services, including updates to those based on the original resource-based relative value scale developed by Hsaio and colleagues. In so doing, widely differing work and services provided can be reviewed and comparisons of their relative value (to each other) can be established. The resource-based relative value scale assigns value to physician services using relative value units (RVUs), which consist of three components: work RVU, practice expense RVU, and malpractice RVU, also known as professional liability insurance RVU. The Centers for Medicare & Medicaid Services retains the final decision-making authority on the RVUs associated with each procedure or service. The purpose of this article is to discuss the role that the CPT codes and the RUC play in the valuation of physician work and to provide an example of how the methodology for valuation of physician work continues to evolve.

Outcome of the Joint Council of Thoracic Surgery Education's Early Review Course Project.

BACKGROUND: The Joint Council on Thoracic Surgical Education was formed in 2008 to improve cardiothoracic education. Resident learning has been a concern as reflected in declining passing rates on the American Board of Thoracic Surgery examinations. The Joint Council on Thoracic Surgical Education piloted a program to determine whether early exposure to a cardiothoracic curriculum through participation in a board review course would improve learning. The purpose of this paper is to report the results of this project. METHODS: Residents from the incoming classes of traditional 5-2 or 5-3 cardiothoracic training programs were randomly selected to attend a 3-day board review course (University of Utah) in September of their first year. For the 2012 and 2013 classes of cardiothoracic residents, we asked all incoming residents to take the prior spring in-training examination in July of their first year and then take the in-training examination in the spring of their first year. We combined the results of the incoming class of 2012 and 2013 and analyzed the results. RESULTS: There were 171 residents who participated in either 2012 or 2013. There were 38 residents (78.9% were men) who attended the board review course and 133 (79.7% men) who did not. Questionnaires completed by the program directors and the residents who took the review course showed a favorable opinion of the program. The number of correct answers on the in-training examination, the percentage correct, and the percentile rank score increased more for the residents who took the review course, but was not statistically significant. When only the general thoracic surgery questions were analyzed, there was a statistically significant increase in the rank change between residents who attended the review course and residents who did not (8.4% increase versus 2.0% decrease, respectively; p = 0.042, Student t test). CONCLUSIONS: This pilot study established for the first time the baseline level of knowledge of incoming residents assessed by the in-training examination. Participation in a board review type course early in the residency training program may increase learning by cardiothoracic residents, but there was not a clear statistical difference between the two groups. The program was viewed as favorable by both the participating residents and the program directors.
