Improving Performance by Improving Education

Education of Fundamental Medical and Surgical Knowledge

“The pain of failure had led me to understand that technical excellence was a moral requirement. Good intentions were not enough, not when so much depended on my skills, when the difference between tragedy and triumph was defined by one or two millimeters.”—Paul Kalanithi, When Breath Becomes Air.

Medical education, by itself, is a daunting task. Modern US health care demands that all providers train equally to the highest level, while tightly limiting the involvement of trainees in patient care and strictly regulating their independence. Despite error being a fundamental human trait, an expectation of perfect care all the time is emerging. Surgical education, and especially neurosurgical education, carries the additional burden of needing to impart technical excellence on top of a solid foundation of clinical knowledge. As the late Dr. Kalanithi describes so aptly, neurosurgeons are held to standards far higher than the average person, and must constantly strive toward asymptotic perfection.

Historically, surgical training had been accomplished through an unregulated apprenticeship model. Following Halsted's triad of educational principles, emphasis was placed on an in-depth understanding of surgical pathologies, repetition of techniques, and, most importantly, graded responsibility and eventual independence. Graduation occurred when one was finally deemed adequately trained and occurred at the discretion of the mentor, with no predefined timeline.

The current-day model for neurosurgical education has evolved in limited but important ways from that of the historical apprenticeship approach. First, the residency training environment is highly regulated (principally by the ACGME; www.acgme.org ) including the creation of a fixed duration of training for the vast majority of trainees. There are now multiple highly vetted mentors contributing to the education of each accredited surgeon as part of a more organized training program with specifically designed, rotating clinical, and other foundational experiences. Finally, a widely established curriculum for North American neurosurgery was recently created for trainees. The “matrix” curriculum was created by residency program directors and other educational specialists, including a multidimensional table that specifies content areas, educational resources, evaluation modalities, and level-specific expectations). Now endorsed by the Society for Neurological Surgeons ( https://www.societyns.org ), representing academic program chairs and residency directors, the matrix curriculum will be housed in an interactive online Portal, which also comprises residency rotation evaluations and reporting tools, by early 2018.

Changes to contemporary medical care, however, have whittled away opportunities for surgical trainees to practice graduated autonomy, weakening the original model implemented by Halsted. Limiting resident work hours, increasing emphasis on attending-driven care, and desire to minimize patient risk have resulted in a gradual decline in opportunities for independent or semiindependent resident practice. While there can be no substitute for the value of actual surgical experience, there are certainly ways to augment a trainee's understanding and baseline technical skill set prior to engaging in the live clinical environment.

A paradigm shift to simulation training is underway in many residency programs. Although simulation has been used for decades, and in the case of cadaveric simulations for centuries, methods of simulation teaching are evolving significantly. Simulated surgical skills training has traditionally used time-based (e.g., 1 h of practice) or repetition-based (e.g., five attempts) methods. More recent data suggest that a third method: proficiency-based teaching—in which trainees deliberately practice on specific high-value techniques with the goal of reaching prespecified benchmarks—is more effective (e.g., laparoscopic suturing exercise requiring completion within 112 s, < 1 mm of stitch error placement, and no knot security errors). However, proficiency-based training necessitates increased planning effort by teaching faculty in order to ascertain appropriate skill goals and develop mastery criteria for learners to strive toward. Proficiency-based teaching itself also requires additional time, small student-to-teacher ratios, and real-time, direct, actionable feedback in order to truly be effective.

Surgical “boot camps” have been utilized recently in neurosurgery to concentrate a series of high-value simulation experiences in a single setting using a large group of faculty with the capacity for an entire cohort of learners at once. This economy of scale has allowed entire classes of US neurosurgery residents to participate in a centrally designed and nationally vetted curriculum intended to ensure a consistent baseline of fundamental technical and behavioral skills. Other focused, high-density surgical courses also allow residents and fellows to learn focused technical skills at more advanced stages of training.

An equally important skill for beginning residents to learn is awareness and management of nontechnical, human factors. Medical errors most commonly occur not as the result of actual technical missteps, but rather from failures of situational awareness, decision-making, communication, and teamwork. For instance, in the operating room, there is often a gap between surgeon and nursing perception of how well the team is working together. Courses that emphasize awareness and insight into these skills improve performance of beginning surgical trainees.

Time-honored classroom didactic teaching is slowly making way for newer integrative educational methods. While deeply rooted in tradition, the classic lecture setting passes on information in a unidirectional fashion—from active presenter to passive audience—leaving little opportunity for learners to practice application of their new found knowledge and critical thinking skills until possibly years later. Instead, educators are increasingly using practice-based learning (PBL) groups and interactive multimedia presentations, resulting in markedly improved test scores.

PBL may involve small student groups given specially vetted scenarios designed to simulate related aspects of anatomy, pathology, and pathophysiology, focusing students on critical thinking, developing self-teaching ability, and synthesizing pertinent data to create an actionable treatment plan. PBL techniques allow simulation of the data gathering and synthesis needed for more effective practice in the live clinical environment. PBL requires less day-to-day preparation of teaching material than proficiency-based learning, as group facilitators are not generally required to be resources for disciplinary knowledge. Conversely, emphasis lies on the facilitator's leadership and guidance skills.

Recent technological advances have also led to information globalization. No longer are students and residents limited to information passed on colloquially. Rather, webinars, forums, and instructional videos all lead to a much wider collaboration and sharing of knowledge and mentorship. National neurosurgical societies have created many online course collections such as the Congress of Neurological Surgeons (CNS)'s “University of Neurosurgery” ( http://learn.cns.org/diweb/start ), and the American Association of Neurological Surgeons (AANS) and Society of Neurological Surgeons (SNS)'s video and podcast collection on iTunes U and YouTube ( http://www.youtube.com/user/AANSNeurosurgery ).

Additionally, the cognitive style and approach of the modern-day student has fundamentally changed due to the advent of the internet and smartphone. Within less than a generation, students have changed from poring over textbooks to near-instantaneous access to worldwide digital information. Students are no longer willing to pursue systematic review and memorization of material when they can retrieve answers in mere seconds. Ubiquitous media influx has led to shortened attention spans and low yield multitasking with worsened retention of presented material and reduced emphasis on critical thinking and problem-solving skills. In a way, technology has created an artificial attention deficit disorder. While the long-term implications of this phenomenonremain obscure, it is apparent that traditional teaching methods are no longer keeping pace with current students of surgery.

In sum, efforts to improve surgical education should include a focus on the extensive challenges to contemporary surgical education outlined above, including loss of opportunities for repetition and practice, outdated teaching methods, decreased training in critical thinking, and underrepresentation of human factor and nontechnical errors. Ultimately, the colossal amount of information, experience, and operative proficiency needed to become an effective, independent neurosurgeon requires an arduous educational process demanding exacting and meticulous results. To fully optimize student and resident learning, we must understand inherent gaps between traditional neurosurgical didacticism and the needs of contemporary learners.
