How We Solved the Shortage of Cardiothoracic Surgeons: Train More or Work Longer

BACKGROUND

In the early 2000s, a significant shortage of cardiothoracic surgeons was predicted. We sought to evaluate our specialty's progress and to update the predicted needs of cardiothoracic surgeons in the coming decades.

METHODS

To assess the supply of cardiothoracic surgeons, the evolution of cardiothoracic surgery training was reviewed. The cardiothoracic surgery workforce and future supply and demand were obtained from the National Center for Health Workforce Analysis. Based on these data, predictions from the early 2000s were compared with the current status, and future supply of cardiothoracic surgeons was modeled.

RESULTS

The number of cardiothoracic surgery trainees increased from 230 in 2008-2009 to 519 in 2022-2023. In 2022-2023, 174 trainees underwent the American Board of Thoracic Surgery Certification Exam, with 129 certificates awarded. From 2005 to 2021, the total number of practicing cardiothoracic surgeons in the United States increased from 4000 to 5200, which contradicts all projections from the early 2000s. The average attrition of 31 cardiothoracic surgeons per year was significantly less than predictive models from the early 2000s. Predictive models project a need of 7000 cardiothoracic surgeons by 2050, which can be met if we continue to fill our available training spots with 173 graduates per year.

CONCLUSIONS

The predicted shortage of cardiothoracic surgeons by midcentury has been overcome by training more cardiothoracic surgeons as well as by a reduction in cardiothoracic surgeon attrition. Future increasing demand can be met by filling our available training positions. Continual assessment of cardiothoracic surgeon supply and demand will help achieve the optimal number of cardiothoracic surgery training positions.

Simulation training for lobectomy: a review of current literature and future directions†

With growing work-time restrictions and public expectations, the Halstedian educational model of 'see one, do one, teach one' is unfit for the modern training of thoracic residents. With the cardiothoracic surgical workforce set to decline by 50% over the next 10 years, new models are desperately needed to help trainees bypass the early error-prone phase of the lobectomy learning curve. In this review, we detail the development and validation of numerous simulators designed to teach trainees an array of skills ranging from basic technical skills to more complex non-technical skills. Given the recent increases in minimally invasive lobectomies, we critique both open and thoracoscopic simulators. We elucidate that whilst there are a growing number of thoracic simulators of varying fidelity available, fundamentally, there is currently a significant lack of well-designed trials validating various simulators for teaching lobectomy despite an awareness of their potential to improve surgical education. Furthermore, there is a void in the simulation training of non-technical skills within thoracic surgery. Encouragingly, there is a definite awareness of the ability of simulation to aid with the training of future thoracic surgical trainees.

Using virtual reality simulation to assess competence in video-assisted thoracoscopic surgery (VATS) lobectomy

BACKGROUND

The societies of thoracic surgery are working to incorporate simulation and competency-based assessment into specialty training. One challenge is the development of a simulation-based test, which can be used as an assessment tool. The study objective was to establish validity evidence for a virtual reality simulator test of a video-assisted thoracoscopic surgery (VATS) lobectomy of a right upper lobe.

METHODS

Participants with varying experience in VATS lobectomy were included. They were familiarized with a virtual reality simulator (LapSim^®) and introduced to the steps of the procedure for a VATS right upper lobe lobectomy. The participants performed two VATS lobectomies on the simulator with a 5-min break between attempts. Nineteen pre-defined simulator metrics were recorded.

RESULTS

Fifty-three participants from nine different countries were included. High internal consistency was found for the metrics with Cronbach's alpha coefficient for standardized items of 0.91. Significant test-retest reliability was found for 15 of the metrics (p-values <0.05). Significant correlations between the metrics and the participants VATS lobectomy experience were identified for seven metrics (p-values <0.001), and 10 metrics showed significant differences between novices (0 VATS lobectomies performed) and experienced surgeons (>50 VATS lobectomies performed). A pass/fail level defined as approximately one standard deviation from the mean metric scores for experienced surgeons passed none of the novices (0 % false positives) and failed four of the experienced surgeons (29 % false negatives).

CONCLUSION

This study is the first to establish validity evidence for a VATS right upper lobe lobectomy virtual reality simulator test. Several simulator metrics demonstrated significant differences between novices and experienced surgeons and pass/fail criteria for the test were set with acceptable consequences. This test can be used as a first step in assessing thoracic surgery trainees' VATS lobectomy competency.

Perceptions and expectations of cardiothoracic residents and attending surgeons

BACKGROUND

With our specialty going through a critical phase of re-evaluation and adaptation, our aim was to evaluate and compare the perceptions and expectations among residents and faculty regarding cardiothoracic training.

METHODS

A content-validated, 13-item survey was distributed electronically from August 14 to August 24, 2010 to 728 cardiothoracic surgery residents, recent program graduates (on or after June 2006), cardiothoracic surgery chairpersons, and program directors identified in the Cardiothoracic Surgery Network database.

RESULTS

The response rate was 34% (244 of 728). Of the respondents, 76% reported being "satisfied" or "very satisfied" with their program. Faculty willingness to teach in the operating room was ranked as the most valuable aspect of a training program, and strict adherence to the 80-h work week ranked as least valuable. Most respondents believed that a resident performing at least 75% of a case was acceptable for low-complexity procedures (92% of residents, 77% of attending physicians) and at least 25% for high-complexity procedures (91% of residents, 73% of attending physicians). However, residents wanted to perform more of the operations than the attending physicians considered necessary (P < 0.05). Finally, 63% of respondents (73% of residents, 56% of attending physicians) indicated that the increasing scrutiny of outcomes has adversely affected training. Other differences between the residents' and attending physicians' perceptions regarded the importance of participation in preoperative and postoperative care, what constitutes "scut work," and the value of auxiliary staff.

CONCLUSIONS

Reconciling residents' expectations with the realities of duty-hour restrictions and high-stakes procedures will require the development of novel educational approaches to improve resident learning.

The cardiac surgery workforce: a survey of recent graduates of Canadian training programs

BACKGROUND

The number of applications to Canadian cardiac surgery programs has declined recently. Perception of a difficult job market for new graduates may contribute to this decline. The objective of this survey was to document the experience of recent graduates of Canadian cardiac surgery training programs.

METHODS

A 45-question, web-based survey was distributed to all graduates of Canadian cardiac surgery training programs who completed their training between 2002 and 2008.

RESULTS

Of the 62 estimated recent graduates, 50 completed the survey (81%). Mean age was 36 + or - 3 years and 90% were male. The mean number of years of training after medical school was 9.4 + or - 1.6 years; 78% completed a graduate degree; and 27% extended their training because of a lack of jobs. When asked about employment, 74% mostly or definitely got the job they wanted, although 34% considered themselves underemployed. Most respondents (98%) considered finding employment for a new graduate in cardiac surgery today difficult or extremely difficult, and 64% believed that there is currently an excess of cardiac surgeons in Canada. Only 54% of participants would strongly recommend cardiac surgery to potential trainees.

CONCLUSIONS

The majority of recent graduates from Canadian cardiac surgery training programs were successful in finding secure employment. A substantial proportion, however, extended their training because of a lack of jobs and reported feeling underemployed. Survey respondents agreed that a new graduate might have difficulty finding a job in cardiac surgery today. These concerns may contribute to the challenges of recruiting to the specialty.
