Insomnia is one of the most common complaints in medicine, driving millions of clinic visits each year (Table 1). It is estimated that approximately 30% of individuals report at least short-term insomnia symptoms and 10% report chronic insomnia. These rates are even higher in groups that may be more susceptible to insomnia, including women, the elderly, and those of disadvantaged socioeconomic status (Ohayon MM. Sleep Med Rev. 2002;[2]:97-111). While most patients with insomnia find their sleep difficulties self-resolve within 3 months, a substantial number of patients will find their insomnia to persist for longer and require intervention (Sateia MJ et al. J Clin Sleep Med. 2017;13[2]:307-49).

For individuals requiring treatment, cognitive behavioral therapy for insomnia (CBT-I) is considered first-line therapy by the American Academy of Sleep Medicine for both acute and chronic insomnia. Unfortunately, obtaining CBT-I for a patient is often a challenge as the number of trained therapists offering this service is limited, resulting in long wait times or, in some cases, a complete lack of access to this treatment option. Judicious use of sedative-hypnotic medications may be a reasonable alternative for patients with insomnia who are unable to undergo CBT-I, who are still symptomatic despite undergoing CBT-I, or, in some cases, as a temporary treatment (Sateia MJ et al. J Clin Sleep Med. 2017;13[2]:307-49).

Current medications used to treat insomnia are listed in Tables 2 and 3, some of which carry an FDA approval to be used as a hypnotic, while others are used in an off-label manner.

Safety, especially in patients of age 65 and older, is an important concern with sleep medication, particularly with respect to polypharmacy, over-sedation, increased fall risk, and cognitive impairment, but daridorexant’s available safety data suggest a favorable safety profile (Zammit G et al. Neurology. 2020;94[21]:e2222-32).

Daridorexant at the highest dose available, 50 mg, did not worsen respiratory function, in terms of the apnea-hypopnea index and oxygen saturation in individuals with mild-moderate obstructive sleep apnea regardless of sleep stage (Boof ML et al. Sleep. 2021;44[6]:zsaa275). However, more safety and longitudinal data are needed to have a fuller understanding of any potential limitations of this medication.

While we continue to recommend CBT-I as the first-line treatment whenever possible for patients with insomnia, not all patients have access to this treatment and not all patients will respond satisfactorily to it. Thus, pharmacologic treatment can continue to play an important role in the management of some patients’ insomnia. Each class of medications used for treating insomnia features a unique constellation of advantages and limitations, meaning that the more available options, the greater the chances of finding an option that will be both effective and safe for a particular patient. The growing DORA class, especially its newest available entrant, daridorexant, represents a continued expansion of the armamentarium of options against insomnia.

There is little I enjoy more than an opportunity to get together with old friends.

I write this missive on the return trip from a week of CHEST leadership meetings held last month, and I find myself filled with joy, awe, and great appreciation for the hard work our volunteers contribute to making the American College of Chest Physicians an extraordinarily productive and successful organization. This year’s meetings meant more than any I can ever recall from the past, in the context of a return to in-person gatherings that let our members share laughs, stories, and even a game or two of laser tag in the context of celebrating good times and friendship. And while some great works were accomplished by our committees, some of which I will enumerate below, the highlight of the week was definitely the esprit de corps that was on broad display.

Our Membership Committee meeting was led by Vice-Chair Marie Budev, DO, FCCP. While this committee is tasked with the critical duty of reviewing applications for the prestigious FCCP designation, they are just as importantly tasked with promoting membership, to our domestic and international colleagues. This is a challenging task, because different members prioritize the variety of benefits from CHEST differently; some focus on access to our educational offerings, both throughout the year and at our annual meeting, while others find greater value in the chance to network with colleagues from around the world and to participate in leadership in an international society. Making sure that we are helping our members realize these benefits, while also identifying (and potentially enhancing) those opportunities in which members are most interested is a challenging task, and I very much enjoyed watching these folks brainstorm ways that we could further increase the value of joining CHEST for current and potential future members.

The Guidelines Oversight Committee, chaired by Lisa Moores, MD, FCCP, is responsible for the oversight of CHEST’s evidence-based guidelines. As our clinical guidelines are among the most highly regarded of all of the things we publish, the members of this committee take special care to ensure that the subjects selected for review as part of the guideline process meet strict criteria. They receive dozens of proposals for new guidelines each year and carefully examine each one to identify the potential public health impact, to ensure the availability of literature in the space worthy of review, and to provide the opportunity to illuminate areas where there are significant clinical uncertainties, often due to new treatments or diagnostic tests. Watching committee members meticulously debate the merits of the many good ideas received to finalize a short list of topics for guideline development in the coming year was incredibly informative and validated my longstanding perception that our members are some of the best clinical minds in the pulmonary, critical care, and sleep fields in the world.

The Professional Standards Committee (PSC), chaired by Scott Manaker, MD, PhD, FCCP, has the important duty of developing CHEST’s conflict of interest (COI) policy, as well as reviewing all potential COI among CHEST leaders and members of our guideline panels. While this may sound a little dry, the fascinating part of this meeting was the ongoing discussion of what constitutes a meaningful COI. As one would expect, many of the best medical experts in the world have relationships with pharmaceutical and medical device companies, who often seek the counsel and participation of high-performing, high-volume clinicians for research trials. CHEST has extremely strict rules with regard to COI among its many levels of leadership, but the question of what constitutes a potentially problematic COI for the large number of folks who volunteer their time and energy to teach at one of our many courses is an interesting (albeit possibly philosophical) question. Since PSC members cannot observe every CHEST faculty interaction, we rely on our members to let us know if they perceive any potential bias in faculty teaching (and we so very much appreciate those of you who bring the extremely rare concerns to our attention!), but this is an area that we continue to watch very closely, as we continue to ensure that all CHEST education is accurate, unbiased, and the best available throughout the world.

The reformulated Council of Networks met under the leadership of Angel Coz Yataco, MD, FCCP, and Cassie Kennedy, MD, FCCP, to discuss how to best engage our members in the new structure, which comprises seven Networks and 22 component Sections. The Council’s primary charges are to develop educational content, to review project applications from Sections, and to serve as expert consultants to the President in their specific clinical domains. While the new configuration provides a significant increase in leadership positions for our members, as well as more formal opportunities to cultivate relationships across different Sections, I have received a few emails from colleagues who were concerned about elimination of certain former Networks, or the placement of a specific Section under a specific Network. Some of these concerns were discussed at the April meeting. While there will be some growing pains, listening to the thoughtful discussion that ensued validated my belief that Drs. Coz and Kennedy are the right folks to be leading the Council as it matures into this new and stronger structure.

While I also had the opportunity to hear reports from the Training and Transitions Committee, the Education Committee, and the Council of Global Governors, I wanted to briefly mention the Scientific Program Committee and its Innovations Group. While we are looking forward to seeing everyone in Nashville this October, I cannot tell you how excited I am about some of the new things we have in store for our first in-person annual meeting in 3 years. (Literally ... I am absolutely sworn to secrecy!) But under the leadership of Program Chair Subani Chandra, MD, FCCP, and my two other “Chief Fun Officers” Aneesa Das, MD, FCCP, and William Kelly, MD, FCCP, I can say that attendees are going to be in for a heck of a lot of fun. Oh, and there’s going to be some education there, also.

In closing, I want to reiterate how much of a pleasure and privilege it has been to sit in the President’s chair over the first few months of 2022. If any of the committees I’ve described above sound interesting to you, please strongly consider throwing your hat into the ring when nominations open up in the coming months. Getting involved at CHEST has been one of the best experiences of my career, and I expect you’ll feel the same way after you join in the fun. As always, I remain available to you, either by emailing me at [email protected] or messaging me on Twitter @ChestPrez. And, please come find me in Nashville in October, either to say hello, or to challenge me to a game of laser tag. ... I’m not very hard to beat.

Until next time,

David

Welcome to Corinne Young, MSN, FNP-C, FCCP, who recently joined the CHEST Physician editorial board to represent and advocate for the perspective of advanced practice providers on the interdisciplinary team.

Young is a nurse practitioner and director of APP and Clinical Services for Colorado Springs Pulmonary Consultants in Colorado. She also is the founder and president of the Association of Pulmonary Advanced Practice Providers, which she created with support from CHEST staff and leaders, who encouraged her to create a community around advocating for and developing credentialing opportunities for this population.

Courtesy ACCP

The idea began early in Young’s career, when, after joining CHEST and attending educational events, she was struck by the lack of standardization in practice she saw among APPs.

“Every time I would be at the CHEST meeting, if I happened to bump into another APP, I would assault them with questions because I didn’t know what the norm was—and come to find out, nobody did,” she said. “Our organization came out of that, and our goal is to eventually standardize the education and knowledge base of APPs.”

Because there is not an option for a national certification specifically for pulmonary medicine for APPs, Young instead attained the FCCP to demonstrate her clinical competency and knowledge. She also immersed herself in the education and community of CHEST, working on the former Clinical Research & Quality Improvement NetWork Committee and Interprofessional Team NetWork Committee, serving on the Scientific Program Committee, and developing patient education on asthma, among other projects.

Now, as a member of the CHEST Physician Editorial Board, Young hopes to build awareness among clinicians of the importance of APPs on the care team and to support another option for APPs to access high-quality education and content to help them build their knowledge and enhance the care they deliver.

“It’s important that CHEST Physician is interested in an APP perspective being included,” she said. “It’s validation that we’re part of the team, that we’re included in all aspects of care including areas outside of direct care: in education, in the literature. ... That they feel our contributions are important.”

When she isn’t working with CHEST or caring for patients, Young and her husband competitively team rope, a rodeo event in which two people work together to rope a steer. Although they were unable to attend, they qualified for the world series in the sport last year, and hope to qualify again this year.

Although attendees will be watching “The Test of the Champion” with bated breath, the upcoming Belmont Stakes Dinner and Auction on June 11 in New York City is about much more than a famous horse race. It’s about community – the vibrant community of clinicians, patients, advocates, and more who support the mission to crush lung disease.

The event started small with a Sunday brunch at the home of CHEST President-Elect Doreen Addrizzo-Harris, MD, FCCP, where attendees gathered to learn more from their host about the CHEST Foundation’s many initiatives. However, over the years, Dr. Addrizzo-Harris leaned on her own community of colleagues, family, friends, and patients to build an event that now boasts hundreds of attendees. But despite all that has changed, the Belmont Stakes Dinner and Auction is still dedicated to raising awareness about the CHEST Foundation and fundraising for initiatives to develop patient education and improve care.

In addition to a plated dinner, silent auction, cocktail reception, and rooftop after-party, this year’s event will feature speeches from two long-time patient advocates living with chronic lung conditions, Fred Schick and Betsy Glaeser.

For Dr. Addrizzo-Harris, spotlighting that unique patient perspective is particularly meaningful because the core focus of CHEST and the CHEST Foundation is to improve care and, by extension, patients’ lives.

In 2020, the CHEST Foundation embarked on a bold new initiative to build trust, identify, and remove barriers, and promote health care access for all in order to help fight lung disease. As part of that, we recognize that racial and ethnic minorities have been underrepresented in medical professions, contributing to these barriers to patient care.

We recognize that advocating for these groups and increasing the number of medical professors who represent people of color, ethnic minority groups, or who come from an historically disadvantaged community also increases the number of role models in our communities and can help stimulate greater interest among minority students in the health care professions. This year, CHEST is joining ATS and ALA in funding the Harold Amos Medical Faculty Development program, and the CHEST Foundation will be raising funds to support these fellowship recipients.

Harold Amos, PhD, was the first African American to chair a department, now the Department of Microbiology and Medical Genetics, of the Harvard Medical School. Dr. Amos worked tirelessly to recruit and mentor minority and disadvantaged students to careers in academic medicine and science. He was a founding member of the National Advisory Committee of the Robert Wood Johnson Foundation’s Minority Medical Faculty Development Program in 1983 and served as the Program’s National Program Director between 1989 and 1993. Dr. Amos remained active with the program until his death in 2003.

This program exists to continue Dr. Amos’s legacy and to increase the number of faculty from historically disadvantaged backgrounds who can achieve senior rank in academic medicine, dentistry, or nursing and who will encourage and foster the development of succeeding classes of such physicians, dentists, and nurse-scientists. The impact of this program is clear.
 

Key results

• Over the past 30 years, 241 scholars had completed all 4 years of the program (as of 2012). More than three-quarters remained in academic medicine, including 57 professors, 76 associate professors, and 56 assistant professors.
• Many program alumni have earned professional honors and become influential leaders in the health care field. For example, three direct institutes at the National Institutes of Health, and 10 have been elected to the Institute of Medicine.
• Alumni have received hundreds of awards and honors, including a MacArthur Fellowship “genius” award.
• Alumni have reached positions of influence in academia that enable them to help correct the underrepresentation of minorities in the health professions and address health disparities.

Former scholars are:

• Members of admission, intern, and faculty selection committees
• On review boards for clinical protocols and research studies
• Officers of professional societies and on editorial boards of academic journals

CHEST is proud to join with ATS and ALA to support this incredible program. We recognize that the impact on the past is only the start. By supporting this initiative, we are also looking to address the challenges of the future as the health care landscape continues to evolve. Ensuring that this program reaches the right groups and continues to promote Dr. Amos’s legacy is integral not only to the success of the program but also to aid us in being able to care for our diverse and unique patient populations. The CHEST Foundation is raising funds to support future fellowship recipients. Join us at our next Viva la Vino wine tasting event on July 14 at 7:00 PM CT. All proceeds go to benefit this important initiative, and you can learn more about the work the Foundation does in a relaxed, social environment.

Treatment with the diabetes drug exenatide was associated with a significant decrease in hyperglycemia in acute stroke patients, a new study shows.

The research could offer clinicians an alternative to insulin therapy to treat hyperglycemia and reduce glucose levels, which are elevated in up to 60% of stroke patients and associated with worse outcomes after stroke.

“Use of these diabetes drugs to control glucose in acute stroke has enormous potential,” said lead researcher Christopher Bladin, PhD, professor of neurology at Monash University and Eastern Health Clinical School, Australia.

The findings were presented at the European Stroke Organisation Conference (ESOC) 2022 annual meeting in Lyon, France.
 

A better fix than insulin?

Hyperglycemia is common in stroke patients, including those who have no prior history of diabetes. Among stroke patients with normal blood glucose upon admission, about 30% will develop hyperglycemia within 48 hours of stroke onset.

Previous research suggests that hyperglycemia is a poor prognostic factor in patients with stroke and may reduce the efficacy of reperfusion therapies such as thrombolysis and mechanical thrombectomy.

“We’ve been looking for different ways of treating hyperglycemia for quite some time, and one of the obvious ways is to use insulin therapy,” Dr. Bladin said. “But as we’ve seen from multiple studies, insulin therapy is difficult.”

Insulin treatment is resource-heavy, significantly increases the risk for hypoglycemia, and some studies suggest the therapy isn’t associated with better outcomes.

An advantage to a GLP-1 agonist-like exenatide, Dr. Bladin added, is that it’s glucose-dependent. As the glucose level falls, the drug’s efficacy diminishes. It is delivered via an autoinjector and easy to administer.

A case for more study

To study exenatide’s efficacy in reducing hyperglycemia and improving neurologic outcomes, researchers developed the phase 2, international, multicenter, randomized controlled TEXAIS trial.

The study enrolled 350 patients following an ischemic stroke. Within 9 hours of stroke onset, patients received either standard care or a subcutaneous injection of 5 mg of exenatide twice daily for 5 days.

On admission, 42% of patients had hyperglycemia, defined as blood glucose > 7.0 mmol/L.

The study’s primary outcome was at least an 8-point improvement in National Institutes of Health Stroke Scale (NIHSS) score by 7 days after treatment with exenatide. Although there was a trend toward better scores with exenatide, the score was not significantly different between groups (56.7% with standard care versus 61.2% with exenatide; adjusted odds ratio, 1.22; P = .38).

However, when the researchers examined hyperglycemia frequency, they found significantly lower incidence in patients treated with exenatide (P = .002).

There were no cases of hypoglycemia in either group, and only 4% of the study group reported nausea or vomiting.

“Clearly exenatide is having some benefit in terms of keeping glucose under control, reducing hyperglycemia,” Dr. Bladin said. “It certainly lends itself to a larger phase 3 study which can look at this more completely.”
 

Value to clinicians

Commenting on the findings, Yvonne Chun, PhD, honorary senior clinical lecturer at University of Edinburgh, noted that, even though the study didn’t find a significant association with improved neurological outcomes, the reduced risk for hypoglycemia makes exenatide an attractive alternative to insulin therapy in stroke patients.

“The results are of value to clinicians, as exenatide could potentially be a safer medication to administer than an insulin infusion in acute stroke patients with hyperglycemia,” Dr. Chun said. “There is less risk of hypoglycemia with exenatide compared to standard care.”

However, Dr. Chun noted that more study is needed before exenatide can replace standard care. Dr. Bladin agrees and would like to pursue a phase 3 trial with a modified design to answer questions raised by Dr. Chun and others.

“The next phase could consider changing the primary outcome to an ordinal shift analysis on modified Rankin Scale – a very commonly used primary outcome in stroke clinical trials to assess improvement in disability,” Dr. Chun said. “The primary outcome used in the presented trial – an 8-point improvement on NIHSS – seemed too ambitious and does not inform disability of the patient post stroke.”

Dr. Bladin said he would also like to see the next phase enroll more patients, examine a higher dose of exenatide, and include better stratification of patients with a history of diabetes. Such a trial could yield findings demonstrating the drug’s effectiveness at reducing hyperglycemia and improving outcomes after stroke, he said.

“I can see the day patients will come in with acute stroke, and as they’re coming into the emergency department, they’ll simply get their shot of exenatide because we know it’s safe to use, and it doesn’t cause hypoglycemia,” Dr. Bladin said. “And from the moment that patient arrives the glucose control is underway.”

Dr. Bladin and Dr. Chun reported no relevant financial relationships. Study funding was not disclosed.

I want to talk about a new continuous glucose monitoring (CGM) metric known as glycemic risk index, or GRI. You may ask why we need another metric. We currently have multiple CGM metrics, including time in range, time below range, time above range, mean glucose, glucose management indicator (GMI), and coefficient of variation, and it seems like an overwhelming number of ways to look at the same data.

The problem is that no single metric tells you exactly what is happening with the patient. For instance, a patient could be at a target time in range of 70%, but that could mean that 30% of that patient’s time is spent too low or even very low, which is a very serious problem, versus if 30% of their time was spent in a somewhat but not very high range, which requires less immediate attention.

Dr. David Klonoff and colleagues, including me, decided to see if one number could be used to identify which patients needed more immediate attention and which needed less. He asked 330 clinicians to evaluate 225 CGM tracings and rank their clinical status in terms of these metrics: very low glucose and low glucose hypoglycemia, very high glucose and high glucose hyperglycemia, time in range, mean glucose, and coefficient of variation.

Then he took all the data and analyzed it in complex ways that I barely understood and came up with one number, the GRI, that captures what the clinicians considered important. The analysis showed that the clinician rankings depended primarily on two components: One related to hypoglycemia, which gives more weight to very low glucose than to low glucose hypoglycemia; and the other related to hyperglycemia, which gives greater weight to very high glucose than to high glucose.

These two components were combined into a single glycemic risk index, the GRI, that corresponds closely to the clinician rankings of the overall quality of glycemia. In terms of numbers, the best GRI is in the zero to 20th percentile and the worst in the 81st to 100th percentile. The GRI grid that is provided in the paper enables users to track sequential changes within an individual over time and compare groups of individuals.

As I said initially, at first I wasn’t sure of the utility of adding yet another number to the mix, but I realized that for triaging what I hope will be increasing amounts of CGM data in a health care system, this could help identify those patients who need the most urgent assistance. It can also help providers have an overall sense of how a patient is doing and whether or not they are improving.

The GRI is not yet in general use and needs to be studied to see if it is actually helpful in clinical practice; however, I like the concept. Given the need to increase provider understanding of CGM metrics overall, I think it is a good way for providers to identify which patients need further analysis of their CGM data for potential treatment modifications.

Thank you.

The problem is that no single metric tells you exactly what is happening with the patient. For instance, a patient could be at a target time in range of 70%, but that could mean that 30% of that patient’s time is spent too low or even very low, which is a very serious problem, versus if 30% of their time was spent in a somewhat but not very high range, which requires less immediate attention.

Dr. David Klonoff and colleagues, including me, decided to see if one number could be used to identify which patients needed more immediate attention and which needed less. He asked 330 clinicians to evaluate 225 CGM tracings and rank their clinical status in terms of these metrics: very low glucose and low glucose hypoglycemia, very high glucose and high glucose hyperglycemia, time in range, mean glucose, and coefficient of variation.

Then he took all the data and analyzed it in complex ways that I barely understood and came up with one number, the GRI, that captures what the clinicians considered important. The analysis showed that the clinician rankings depended primarily on two components: One related to hypoglycemia, which gives more weight to very low glucose than to low glucose hypoglycemia; and the other related to hyperglycemia, which gives greater weight to very high glucose than to high glucose.

These two components were combined into a single glycemic risk index, the GRI, that corresponds closely to the clinician rankings of the overall quality of glycemia. In terms of numbers, the best GRI is in the zero to 20th percentile and the worst in the 81st to 100th percentile. The GRI grid that is provided in the paper enables users to track sequential changes within an individual over time and compare groups of individuals.

As I said initially, at first I wasn’t sure of the utility of adding yet another number to the mix, but I realized that for triaging what I hope will be increasing amounts of CGM data in a health care system, this could help identify those patients who need the most urgent assistance. It can also help providers have an overall sense of how a patient is doing and whether or not they are improving.

The GRI is not yet in general use and needs to be studied to see if it is actually helpful in clinical practice; however, I like the concept. Given the need to increase provider understanding of CGM metrics overall, I think it is a good way for providers to identify which patients need further analysis of their CGM data for potential treatment modifications.

Thank you.

It was such a pleasure at the 48th Annual Meeting of the Society of Gynecologic Surgeons (SGS) to witness record meeting attendance and strong enthusiasm after 2 depressing years with the COVID-19 pandemic. Evidently, everyone was tired of virtual gatherings and presentations. As a dedicated surgical educator and a passionate vaginal surgeon, SGS President Carl Zimmerman, MD, chose “Gynecologic surgery training: Lessons from the past, looking to the future” as the theme for this year’s meeting. Our keynote speakers, Patricia Turner, MD, MBA, Executive Director of the American College of Surgeons, and Marta Crispens, MD, MBA, Professor and Division Director of Gynecologic Oncology at Vanderbilt, were spot on. They reviewed the current status of surgical training eloquently with convincing statistics. They mapped out the path forward by stressing collaboration and proposing strategies that might produce competent surgeons in all fields.

The meeting featured 2 panel discussions. The first, titled “Innovations in training gynecologic surgeons,” reviewed tracking in residency, use of simulation for surgical proficiency, and European perspective on training. The panelists emphasized the dwindling numbers of surgical procedures, especially vaginal hysterectomies. Cecile Ferrando, MD, suggested that tracking might be part of the answer, based on their experience, which provided a structure for residents to obtain concentrated training in their areas of interest. Douglas Miyazaki, MD, presented the prospects for his innovative, federally funded vaginal surgery simulation model. Oliver Preyer, MD, presented Austrian trainees’ low case volumes, showing that the grass was not actually greener on the other side. Finally, this panel reinvigorated ongoing debate about separating Obstetrics and Gynecology.

The second panel, “Operating room safety and efficiency,” shed light on human and nontechnical factors that might be as critical as surgeons’ skills and experience, and it highlighted an innovative technology that monitored and analyzed all operating room parameters to improve operational processes and surgical technique. Points by Jason Wright, MD, on the relationship between surgical volume and outcomes complemented the meeting theme and the first panel discussion. He underlined how much surgical volume of individual surgeons and hospitals mattered, but he also indicated that restrictive credentialing strategies might lead to unintended consequences.

Importantly, the SGS Women’s Council held a panel on the “Impact of Texas legislation on the physician/patient relationship” to provide a platform for members who had mixed feelings about attending this meeting in Texas.

The SGS meeting also included several popular postgraduate courses on multidisciplinary management of Müllerian anomalies, pelvic fistula treatment, surgical simulation, management modalities for uterine fibroids, and medical innovation and entrepreneurship. In this special section and in the next issue of OBG Management, several of these topics are presented.

Vaginal surgery, including vaginal hysterectomy, is slowly becoming a dying art. According to the National Inpatient Sample and the Nationwide Ambulatory Surgery Sample from 2018, only 11.8% of all hysterectomies were performed vaginally.¹ The combination of uterine-sparing surgeries, advances in conservative therapies for benign uterine conditions, and the diversification of minimally invasive routes (laparoscopic and robotic) has resulted in a continued downtrend in vaginal surgical volumes. This shift has led to fewer operative learning opportunities and declining graduating resident surgical volume.² According to the Accreditation Council for Graduate Medical Education (ACGME), the minimum number of vaginal hysterectomies is 15, which represents only the minimum accepted exposure and does not imply competency.

In response, surgical simulation has been used for skill acquisition and maintenance outside of the operating room in a learning environment that is safe for the learners and does not expose patients to additional risk. Educators are uniquely poised to use simulation to teach residents and to evaluate their procedural competency. Although vaginal surgery, specifically vaginal hysterectomy, continues to decline, it can be resuscitated with the assistance of surgical simulation.

In this article, we provide a broad overview of vaginal surgical simulation. We discuss the basic tenets of simulation, review how to teach and evaluate vaginal surgical skills, and present some of the commonly available vaginal surgery simulation models and their associated resources, cost, setup time, fidelity, and limitations.

Simulation principles relevant for vaginal hysterectomy simulation

Here, we review simulation-based learning principles that will help place specific simulation models into perspective.

One size does not fit all

Simulation, like many educational interventions, does not work via a “one-size-fits-all” approach. While the American College of Obstetricians and Gynecologists (ACOG) Simulations Working Group (SWG) has created a toolkit (available online at https://www.acog.org/education-and-events/simulations/about/curriculum) with many ready-to-use how-to simulation descriptions and lesson plans that cover common topics, what works in one setting may not work in another. The SWG created those modules to help educators save time and resources and to avoid reinventing the wheel for each simulation session. However, these simulations need to be adapted to the local needs of trainees and resources, such as faculty time, space, models, and funding.

Cost vs fidelity

It is important to distinguish between cost and fidelity. “Low cost” is often incorrectly used interchangeably with “low fidelity” when referring to models and simulations. The most basic principle of fidelity is that it is associated with situational realism that in turn, drives learning.^3,4 For example, the term high fidelity does apply to a virtual reality robotic surgery simulator, which also is high cost. However, a low-cost beef tongue model of fourth-degree laceration⁵ is high fidelity, while more expensive commercial models are less realistic, which makes them high cost and low fidelity.⁶ When selecting simulation models, educators need to consider cost based on their available resources and the level of fidelity needed for their learners.

Task breakdown

As surgeon-educators, we love to teach! And while educators are passionate about imparting vaginal hysterectomy skills to the next generation of surgeons, it is important to assess where the learners are technically. Vaginal hysterectomy is a high-complexity procedure, with each step involving a unique skill set that is new to residents as learners; this is where the science of learning can help us teach more effectively.⁷ Focusing on doing the entire procedure all at once is more likely to result in cognitive overload, while a better approach is to break the procedure down into several components and practice those parts until goal proficiency is reached.

Deliberate practice

The idea of deliberate practice was popularized by Malcolm Gladwell in his book titled Outliers, in which he gives examples of how 10,000 hours of practice leads to mastery of complex skills. This concept was deepened by the work of cognitive psychologist Anders Ericsson, who emphasized that not only the duration but also the quality of practice—which involves concentration, analysis, and problem-solving—leads to the most effective training.⁸

In surgical education, this concept translates into many domains. For example, an individualized learning plan includes frequent low-stakes assessments, video recording for later viewing and analysis, surgical coaching, and detailed planning of future training sessions to incorporate past performance. “Just doing” surgery on a simulator (or in the operating room) results in missed learning opportunities.

Logistics and implementation: Who, where, when

The simulation “formula” takes into account multiple factors but should start with learning objectives and then an assessment of what resources are available to address them. For example, if one surgeon-educator and one resident-learner are available for 30 minutes in between cases in the operating room, and the goal is to teach the resident clamp-and-tie technique on pedicles, the “milk carton” model⁹ and a few instruments from the vaginal hysterectomy tray are ideal for this training. On the other hand, if it is important to achieve competency for an entire procedure prior to operating room debut and a group of surgeon-educators is available to share the time commitment of 2-hour sessions per each resident, then the PROMPT (PRactical Obstetric Multi-Professional Training) shoulder dystocia model could be used (TABLE).^10-14

Learning curves

Ideally, educators would like to know how many simulated training sessions are needed for a learner to reach a proficiency level and become operating room ready. Such information about learning curves, unfortunately, is not available yet for vaginal hysterectomies. The first step in the process is to establish a baseline for performance to know a starting point, with assessment tools specific to each simulator; the next step is to study how many “takes” are needed for learners to move through their learning curve.¹⁵ The use of assessment tools can help assess each learner’s progression.

Continue to: Evaluation, assessment, and feedback...

With more emphasis being placed on patient safety and transparency in every aspect of health care, including surgical training, graduate medical education leaders increasingly highlight the importance of objective assessment tools and outcome-based standards for certification of competency in surgery.^16,17 Commonly used assessment tools that have reliability and validity evidence include surgical checklists and global rating scales. Checklists for common gynecologic procedures, including vaginal hysterectomy, as well as a global rating scale specifically developed for vaginal surgery (Vaginal Surgical Skills Index, VSSI)¹⁸ are accessible on the ACOG Simulations Working Group Surgical Curriculum in Obstetrics and Gynecology website.¹⁹

While checklists contain the main steps of each procedure, these lists do not assess for how well each step of the procedure is performed. By contrast, global rating scales, such as the VSSI, can discriminate between surgeons with different skill levels both in the simulation and operating room settings; each metric within the global rating scale (for example, time and motion) does not pertain to the performance of a procedure’s specific step but rather to the overall performance of the entire procedure.^18,20 Hence, to provide detailed feedback, especially for formative assessment, both checklists and global rating scales often are used together.

Although standardized, checklists and global rating scales ultimately are still subjective (not objective) assessment tools. Recently, more attention has been to use surgical data science, particularly artificial intelligence methods, to objectively assess surgical performance by analyzing data generated during the performance of surgery, such as instrumental motion and video.²¹ These methods have been applied to a wide range of surgical techniques, including open, laparoscopic, robotic, endoscopic, and microsurgical approaches. Most of these types of studies have used assessment of surgical skill as the main outcome, with fewer studies correlating skill with clinically relevant metrics, such as patient outcomes.^22-25 Although this is an area of active research, these methods are still being developed, and their validity and utility are not well established. For now, educators should continue to use validated checklists and global rating skills to help assess any type of surgical performance, particularly vaginal surgery.

Vaginal surgical simulation models

Vaginal surgery requires a surgeon to operate in a narrow, deep space. This requires ambidexterity, accurate depth perception, understanding of how to handle tissues, and use of movements that are efficient, fluid, and rhythmic. Multiple proposed simulation models are relevant to vaginal surgery, and these vary based on level of fidelity, cost, feasibility, ability to maintain standardization, ease of construction (if required), and generalizability to all of pelvic surgery (that is, procedure specific vs basic skills focused).^{10,11,13,26-31}

Below, we describe various simulation models that are available for teaching vaginal surgical skills.

Vaginal hysterectomy simulation model

One commercially available simulation model for vaginal hysterectomy (as well as other vaginal surgical procedures, such as midurethral sling and anterior and posterior colporrhaphy) is the Miya Model (Miyazaki Enterprises) (FIGURE 1) and its accompanying MiyaMODEL App. In a multi-institutional study funded by the National Institutes of Health (NIH), the Miya Model, when used with the VSSI, was shown to be a valid assessment tool in terms of ability to differentiate a competent from a noncompetent surgeon.²⁰ Currently, an ongoing NIH-sponsored multi-institutional study is assessing the Miya Model as a teaching tool and whether skills acquired on the Miya Model are transferable to the operating room.

Continue to: Low-cost vaginal hysterectomy models...

Multiple low-cost vaginal hysterectomy simulation models are described. Two models developed many years ago include the ACOG SWG flowerpot model¹⁴ and the PROMPT shoulder dystocia pelvic trainer model.^10,11,14 The former model is low cost as it can be constructed from easily obtained household materials, but its downside is that it takes time and effort to obtain the materials and to assemble them. The latter model is faster to assemble but requires one to use a PROMPT pelvis for shoulder dystocia training, which has a considerable upfront cost. However, it is available in most hospitals with considerable obstetrical volume, and it allows for the most realistic perineum, which is helpful in recreating the feel of vaginal surgery, including retraction and exposure.

Many models created and described in the literature are variations of the models mentioned above, and many use commercially available low-cost bony pelvis models and polyvinyl chloride (PVC) pipes as a foundation for the soft tissue inserts to attach.^12,13,31-33 Each model varies on what it “teaches best” regarding realism—for example, teaching anatomy, working in a tight space, dissection, or clamp placement and suture ligature.

Furthermore, since vaginal hysterectomy is a high-complexity procedure in terms of skills (working in confined space, limited view, “upside-down” anatomy, and need to direct assistants for retraction and exposure), task breakdown is important for simulation learning, as it is not efficient to repeat the entire procedure until proficiency is reached. Two trainers have been described to address that need: the milk carton and the vaginal suturing trainer. The latter allows learners to practice clamp placement and pedicle ligation multiple times, including in confined space (FIGURE 2), and the former allows them to do the same in a procedural matter as the clamp placement moves caudad to cephalad during the procedure (FIGURE 3).

Native tissue pelvic floor surgery simulation

While there are few publications regarding surgical simulation models for native tissue pelvic floor surgeries, a low-cost anterior and posterior repair model was developed for the ACOG SWG Simulation Toolkit and published online in 2017, after their peer-review process. The fidelity is moderate for this low-cost model, which costs less than $5 per use. The simulation model requires a new vaginal insert for each learner, which is fast and easy to make and requires only a few components; however, the bony pelvis (for example, the flowerpot model) needs to be purchased or created. The stage of the anterior wall prolapse can be adjusted by the amount of fluid placed in the balloon, which is used to simulate the bladder. The more fluid that is placed in the “bladder,” the more severe the anterior wall prolapse appears. The vaginal caliber can be adjusted, if needed, by increasing or decreasing the size of the components to create the vagina, but the suggested sizes simulate a significantly widened vaginal caliber that would benefit from a posterior repair with perineorrhaphy. Although there is no validity evidence for this model, a skills assessment is available through the ACOG Simulation Surgical Curriculum. Of note, native tissue colpopexy repairs are also possible with this model (or another high-fidelity model, such as the Miya Model), if the sacrospinous ligaments and/or uterosacral ligaments are available on the pelvic model in use. This model’s limitations include the absence of a high-fidelity plane of dissection of the vaginal muscularis, and that no bleeding is encountered, which is the case for many low-cost models.^19,34

Fundamentals of Vaginal Surgery (FVS) basic surgical skills simulation

The FVS simulation system, consisting of a task trainer paired with 6 selected surgical tasks, was developed to teach basic skills used in vaginal surgery.³⁵ The FVS task trainer is 3D printed and has 3 main components: a base piece that allows for different surgical materials to be secured, a depth extender, and a width reducer. In addition, it has a mobile phone mount and a window into the system to enable video capture of skills exercises.

The FVS simulator is designed to enable 6 surgical tasks, including one-handed knot tying, two-handed knot tying, running suturing, plication suturing, Heaney transfixion pedicle ligation, and free pedicle ligation (FIGURE 4). In a pilot study, the FVS simulation system was deemed representative of the intended surgical field, useful for inclusion in a training program, and favored as a tool for both training and testing. Additionally, an initial proficiency score of 400 was set, which discriminated between novice and expert surgeons.³⁵

An advantage of this simulation system is that it allows learners to focus on basic skills, rather than on an entire specific procedure. Further, the system is standardized, as it is commercially manufactured; this also allows for easy assembly. The disadvantage of this model is that it cannot be modified to teach specific vaginal procedures, and it must be purchased, rather than constructed on site. Further studies are needed to create generalizable proficiency scores and to assess its use in training and testing. For more information on the FVS simulation model, visit the Arbor Simulation website (http://arborsim.com).

Surgical simulation’s important role

Surgical skills can be learned and improved in the simulation setting in a low-stakes, low-pressure environment. Simulation can enable basic skills development and then higher-level learning of complex procedures. Skill assessment is important to aid in learning (via formative assessments) and for examination or certification (summative assessments).

With decreasing vaginal surgical volumes occurring nationally, it is becoming even more important to use surgical simulation to teach and maintain vaginal surgical skills. In this article, we reviewed various different simulation models that can be used for developing vaginal surgical skills and presented the advantages, limitations, and resources relevant for each simulation model. ●

Recently, more attention has been to use surgical data science, particularly artificial intelligence methods, to objectively assess surgical performance by analyzing data generated during the performance of surgery, such as instrumental motion and video.²¹ These methods have been applied to a wide range of surgical techniques, including open, laparoscopic, robotic, endoscopic, and microsurgical approaches. Most of these types of studies have used assessment of surgical skill as the main outcome, with fewer studies correlating skill with clinically relevant metrics, such as patient outcomes.^22-25 Although this is an area of active research, these methods are still being developed, and their validity and utility are not well established. For now, educators should continue to use validated checklists and global rating skills to help assess any type of surgical performance, particularly vaginal surgery.

Vaginal surgical simulation models

Vaginal surgery requires a surgeon to operate in a narrow, deep space. This requires ambidexterity, accurate depth perception, understanding of how to handle tissues, and use of movements that are efficient, fluid, and rhythmic. Multiple proposed simulation models are relevant to vaginal surgery, and these vary based on level of fidelity, cost, feasibility, ability to maintain standardization, ease of construction (if required), and generalizability to all of pelvic surgery (that is, procedure specific vs basic skills focused).^{10,11,13,26-31}

Below, we describe various simulation models that are available for teaching vaginal surgical skills.

Vaginal hysterectomy simulation model

One commercially available simulation model for vaginal hysterectomy (as well as other vaginal surgical procedures, such as midurethral sling and anterior and posterior colporrhaphy) is the Miya Model (Miyazaki Enterprises) (FIGURE 1) and its accompanying MiyaMODEL App. In a multi-institutional study funded by the National Institutes of Health (NIH), the Miya Model, when used with the VSSI, was shown to be a valid assessment tool in terms of ability to differentiate a competent from a noncompetent surgeon.²⁰ Currently, an ongoing NIH-sponsored multi-institutional study is assessing the Miya Model as a teaching tool and whether skills acquired on the Miya Model are transferable to the operating room.

Multiple low-cost vaginal hysterectomy simulation models are described. Two models developed many years ago include the ACOG SWG flowerpot model¹⁴ and the PROMPT shoulder dystocia pelvic trainer model.^10,11,14 The former model is low cost as it can be constructed from easily obtained household materials, but its downside is that it takes time and effort to obtain the materials and to assemble them. The latter model is faster to assemble but requires one to use a PROMPT pelvis for shoulder dystocia training, which has a considerable upfront cost. However, it is available in most hospitals with considerable obstetrical volume, and it allows for the most realistic perineum, which is helpful in recreating the feel of vaginal surgery, including retraction and exposure.

Many models created and described in the literature are variations of the models mentioned above, and many use commercially available low-cost bony pelvis models and polyvinyl chloride (PVC) pipes as a foundation for the soft tissue inserts to attach.^12,13,31-33 Each model varies on what it “teaches best” regarding realism—for example, teaching anatomy, working in a tight space, dissection, or clamp placement and suture ligature.

Furthermore, since vaginal hysterectomy is a high-complexity procedure in terms of skills (working in confined space, limited view, “upside-down” anatomy, and need to direct assistants for retraction and exposure), task breakdown is important for simulation learning, as it is not efficient to repeat the entire procedure until proficiency is reached. Two trainers have been described to address that need: the milk carton and the vaginal suturing trainer. The latter allows learners to practice clamp placement and pedicle ligation multiple times, including in confined space (FIGURE 2), and the former allows them to do the same in a procedural matter as the clamp placement moves caudad to cephalad during the procedure (FIGURE 3).

Native tissue pelvic floor surgery simulation

While there are few publications regarding surgical simulation models for native tissue pelvic floor surgeries, a low-cost anterior and posterior repair model was developed for the ACOG SWG Simulation Toolkit and published online in 2017, after their peer-review process. The fidelity is moderate for this low-cost model, which costs less than $5 per use. The simulation model requires a new vaginal insert for each learner, which is fast and easy to make and requires only a few components; however, the bony pelvis (for example, the flowerpot model) needs to be purchased or created. The stage of the anterior wall prolapse can be adjusted by the amount of fluid placed in the balloon, which is used to simulate the bladder. The more fluid that is placed in the “bladder,” the more severe the anterior wall prolapse appears. The vaginal caliber can be adjusted, if needed, by increasing or decreasing the size of the components to create the vagina, but the suggested sizes simulate a significantly widened vaginal caliber that would benefit from a posterior repair with perineorrhaphy. Although there is no validity evidence for this model, a skills assessment is available through the ACOG Simulation Surgical Curriculum. Of note, native tissue colpopexy repairs are also possible with this model (or another high-fidelity model, such as the Miya Model), if the sacrospinous ligaments and/or uterosacral ligaments are available on the pelvic model in use. This model’s limitations include the absence of a high-fidelity plane of dissection of the vaginal muscularis, and that no bleeding is encountered, which is the case for many low-cost models.^19,34

Fundamentals of Vaginal Surgery (FVS) basic surgical skills simulation

The FVS simulation system, consisting of a task trainer paired with 6 selected surgical tasks, was developed to teach basic skills used in vaginal surgery.³⁵ The FVS task trainer is 3D printed and has 3 main components: a base piece that allows for different surgical materials to be secured, a depth extender, and a width reducer. In addition, it has a mobile phone mount and a window into the system to enable video capture of skills exercises.

The FVS simulator is designed to enable 6 surgical tasks, including one-handed knot tying, two-handed knot tying, running suturing, plication suturing, Heaney transfixion pedicle ligation, and free pedicle ligation (FIGURE 4). In a pilot study, the FVS simulation system was deemed representative of the intended surgical field, useful for inclusion in a training program, and favored as a tool for both training and testing. Additionally, an initial proficiency score of 400 was set, which discriminated between novice and expert surgeons.³⁵

An advantage of this simulation system is that it allows learners to focus on basic skills, rather than on an entire specific procedure. Further, the system is standardized, as it is commercially manufactured; this also allows for easy assembly. The disadvantage of this model is that it cannot be modified to teach specific vaginal procedures, and it must be purchased, rather than constructed on site. Further studies are needed to create generalizable proficiency scores and to assess its use in training and testing.

Surgical simulation’s important role

Surgical skills can be learned and improved in the simulation setting in a low-stakes, low-pressure environment. Simulation can enable basic skills development and then higher-level learning of complex procedures. Skill assessment is important to aid in learning (via formative assessments) and for examination or certification (summative assessments).

With decreasing vaginal surgical volumes occurring nationally, it is becoming even more important to use surgical simulation to teach and maintain vaginal surgical skills. In this article, we reviewed various different simulation models that can be used for developing vaginal surgical skills and presented the advantages, limitations, and resources relevant for each simulation model. ●

Vaginal surgery, including vaginal hysterectomy, is slowly becoming a dying art. According to the National Inpatient Sample and the Nationwide Ambulatory Surgery Sample from 2018, only 11.8% of all hysterectomies were performed vaginally.¹ The combination of uterine-sparing surgeries, advances in conservative therapies for benign uterine conditions, and the diversification of minimally invasive routes (laparoscopic and robotic) has resulted in a continued downtrend in vaginal surgical volumes. This shift has led to fewer operative learning opportunities and declining graduating resident surgical volume.² According to the Accreditation Council for Graduate Medical Education (ACGME), the minimum number of vaginal hysterectomies is 15, which represents only the minimum accepted exposure and does not imply competency.

In response, surgical simulation has been used for skill acquisition and maintenance outside of the operating room in a learning environment that is safe for the learners and does not expose patients to additional risk. Educators are uniquely poised to use simulation to teach residents and to evaluate their procedural competency. Although vaginal surgery, specifically vaginal hysterectomy, continues to decline, it can be resuscitated with the assistance of surgical simulation.

In this article, we provide a broad overview of vaginal surgical simulation. We discuss the basic tenets of simulation, review how to teach and evaluate vaginal surgical skills, and present some of the commonly available vaginal surgery simulation models and their associated resources, cost, setup time, fidelity, and limitations.

Simulation principles relevant for vaginal hysterectomy simulation

Here, we review simulation-based learning principles that will help place specific simulation models into perspective.

One size does not fit all

Simulation, like many educational interventions, does not work via a “one-size-fits-all” approach. While the American College of Obstetricians and Gynecologists (ACOG) Simulations Working Group (SWG) has created a toolkit (available online at https://www.acog.org/education-and-events/simulations/about/curriculum) with many ready-to-use how-to simulation descriptions and lesson plans that cover common topics, what works in one setting may not work in another. The SWG created those modules to help educators save time and resources and to avoid reinventing the wheel for each simulation session. However, these simulations need to be adapted to the local needs of trainees and resources, such as faculty time, space, models, and funding.

Cost vs fidelity

It is important to distinguish between cost and fidelity. “Low cost” is often incorrectly used interchangeably with “low fidelity” when referring to models and simulations. The most basic principle of fidelity is that it is associated with situational realism that in turn, drives learning.^3,4 For example, the term high fidelity does apply to a virtual reality robotic surgery simulator, which also is high cost. However, a low-cost beef tongue model of fourth-degree laceration⁵ is high fidelity, while more expensive commercial models are less realistic, which makes them high cost and low fidelity.⁶ When selecting simulation models, educators need to consider cost based on their available resources and the level of fidelity needed for their learners.

Task breakdown

As surgeon-educators, we love to teach! And while educators are passionate about imparting vaginal hysterectomy skills to the next generation of surgeons, it is important to assess where the learners are technically. Vaginal hysterectomy is a high-complexity procedure, with each step involving a unique skill set that is new to residents as learners; this is where the science of learning can help us teach more effectively.⁷ Focusing on doing the entire procedure all at once is more likely to result in cognitive overload, while a better approach is to break the procedure down into several components and practice those parts until goal proficiency is reached.

Deliberate practice

The idea of deliberate practice was popularized by Malcolm Gladwell in his book titled Outliers, in which he gives examples of how 10,000 hours of practice leads to mastery of complex skills. This concept was deepened by the work of cognitive psychologist Anders Ericsson, who emphasized that not only the duration but also the quality of practice—which involves concentration, analysis, and problem-solving—leads to the most effective training.⁸

In surgical education, this concept translates into many domains. For example, an individualized learning plan includes frequent low-stakes assessments, video recording for later viewing and analysis, surgical coaching, and detailed planning of future training sessions to incorporate past performance. “Just doing” surgery on a simulator (or in the operating room) results in missed learning opportunities.

Logistics and implementation: Who, where, when

The simulation “formula” takes into account multiple factors but should start with learning objectives and then an assessment of what resources are available to address them. For example, if one surgeon-educator and one resident-learner are available for 30 minutes in between cases in the operating room, and the goal is to teach the resident clamp-and-tie technique on pedicles, the “milk carton” model⁹ and a few instruments from the vaginal hysterectomy tray are ideal for this training. On the other hand, if it is important to achieve competency for an entire procedure prior to operating room debut and a group of surgeon-educators is available to share the time commitment of 2-hour sessions per each resident, then the PROMPT (PRactical Obstetric Multi-Professional Training) shoulder dystocia model could be used (TABLE).^10-14

Learning curves

Ideally, educators would like to know how many simulated training sessions are needed for a learner to reach a proficiency level and become operating room ready. Such information about learning curves, unfortunately, is not available yet for vaginal hysterectomies. The first step in the process is to establish a baseline for performance to know a starting point, with assessment tools specific to each simulator; the next step is to study how many “takes” are needed for learners to move through their learning curve.¹⁵ The use of assessment tools can help assess each learner’s progression.

Continue to: Evaluation, assessment, and feedback...

With more emphasis being placed on patient safety and transparency in every aspect of health care, including surgical training, graduate medical education leaders increasingly highlight the importance of objective assessment tools and outcome-based standards for certification of competency in surgery.^16,17 Commonly used assessment tools that have reliability and validity evidence include surgical checklists and global rating scales. Checklists for common gynecologic procedures, including vaginal hysterectomy, as well as a global rating scale specifically developed for vaginal surgery (Vaginal Surgical Skills Index, VSSI)¹⁸ are accessible on the ACOG Simulations Working Group Surgical Curriculum in Obstetrics and Gynecology website.¹⁹

While checklists contain the main steps of each procedure, these lists do not assess for how well each step of the procedure is performed. By contrast, global rating scales, such as the VSSI, can discriminate between surgeons with different skill levels both in the simulation and operating room settings; each metric within the global rating scale (for example, time and motion) does not pertain to the performance of a procedure’s specific step but rather to the overall performance of the entire procedure.^18,20 Hence, to provide detailed feedback, especially for formative assessment, both checklists and global rating scales often are used together.
