Controlled Burn: Managing the "Forest Fire" of Leaving a Professional Identity in Medical Education.

INTRODUCTION: Professional identity formation is central to physicians' identity over their full careers. There is little guidance within military service on how to leave careers as clinician educator faculty in graduate medical education programs. The objective of our study was to explore how leaving this community of practice (COP) affects a clinician educator's professional identity. METHODS: We used reflexive thematic analysis with Communities of Practice as a sensitizing construct. Fifteen semi-structured interviews were conducted among active-duty clinician educators at the point of their retirement from the military. Interview questions focused participants' lived experiences as clinician educators and professional identity changes leading to and resulting from the decision to retire. RESULTS: We found the clinician educators' journey through a time of professional transition led to three connected themes: Loss Precedes Growth, Fallow Season-Liminal Space, and New Growth. DISCUSSION: The experiences of military clinician educators retiring from active duty demonstrate how leaving one COP emanates across a range of professional identities. In addition, the decision to leave a professional COP can lead to a sense of disloyalty to that community. Normalizing this transition in a way that honors the community's values offers the opportunity to enable the decision to retire. Understanding retirement as a process that first involves identity loss, followed by the discomfort of a liminal space before achieving new growth creates the opportunity to engage in rituals that celebrate the service of departing community members, releasing them to grow into new identities.

A Common Trajectory Toward a Professional Identity as a Faculty Developer.

BACKGROUND AND OBJECTIVES: Professional identity formation is a complex construct that continually evolves in relation to an individual's experiences. The literature on educators identifying as faculty developers is limited and incompletely addresses how that identify affects other identities, careers, and influences on teaching. Twenty-six health professionals were trained to serve as faculty developers within our educational system. We sought to examine the factors that influence the professional identity of these faculty developers and to determine whether a common trajectory existed. METHODS: We employed a constructivist thematic analysis methodology using an inductive approach to understand the experiences of faculty developers. We conducted semistructured recorded interviews. Coding and thematic analysis were completed iteratively. RESULTS: We identified eight primary themes: (1) initial invitation, (2) discovery of faculty development as a professional activity, (3) discovery of educational theory, skills, and need for more education, (4) process of time and experience, (5) fostering relationships and community, (6) transfer of skills to professional and personal roles, (7) experiences that lead to credibility, and (8) sense of greater impact. CONCLUSIONS: An individual's journey to a faculty developer identity is variable, with several shared pivotal experiences that help foster the emergence of this identity. Consideration of specific programmatic elements to support the themes identified might allow for a strategic approach to faculty development efforts in health professions education.

Do All Roads Lead to Full Participation? Examining Trajectories of Clinical Educators in Graduate Medical Education through Situated Learning Theory.

Phenomenon: As new faculty members begin their careers in Graduate Medical Education, each begins a journey of Professional Identity Formation from the periphery of their educational communities. The trajectories traveled vary widely, and full participation in a given educational community is not assured. While some medical school and post-graduate training programs may nurture Professional Identity Formation, there is scant support for faculty. To date, the trajectories that Graduate Medical Education faculty travel, what may derail inbound trajectories, and what tools Graduate Medical Education faculty use to navigate these trajectories have not been explicitly described. We explore these three questions here. Approach: Communities of Practice, a component of Situated Learning Theory, serves as a helpful framework to explore trajectories of educator identity development among Graduate Medical Educators. We used a inductive and deductive approach to Thematic Analysis, with Situated Learning Theory as our interpretive frame. Semi-structured interviews of faculty members of GME programs matriculating into a Health Professions Education Program were conducted, focusing on participants' lived experiences in medical education and how these experiences shaped their Professional Identity Formation. Findings: Participants noted peripheral, inbound, boundary, and outbound trajectories, but not an insider trajectory. Trajectory derailment was attributed to competing demands, imposter syndrome and gendered marginality. Modes of belonging were critical tools participants used to shape PIF, not only engagement with educator roles but disengagement with other roles; imagination of future roles with the support of mentors; and fluid alignment with multiple mutually reinforcing identities. Participants identified boundary objects like resumes and formal roles that helped them negotiate across Community of Practice boundaries. Insights: Despite a desire for full participation, some clinical educators remain marginal, struggling along a peripheral trajectory. Further research exploring this struggle and potential interventions to strengthen modes of belonging and boundary objects is critical to create equitable access to the inbound trajectory for all of our colleagues, leaving the choice of trajectories up to them.

The Making of an Educator: Professional Identity Formation Among Graduate Medical Education Faculty Through Situated Learning Theory.

INTRODUCTION: Professional identity formation (PIF) is a foundational element to professional medical education and training. Given the impact of faculty role models and mentors to student and trainee learning, mapping the landscape of PIF among faculty takes on increased importance. We conducted a scoping review of PIF through the lens of situated learning theory. Our scoping review question was: How is situated learning theory used to understand the process of PIF among graduate medical educators? METHODS: The scoping review methodology described by Levac et al served as the architecture for this review. Medline, Embase, PubMed, ERIC, CINAHL, PsycINFO, and Web of Science Core Collection were searched (from inception) using a combination of terms that describe PIF among graduate medical educators. RESULTS: Of the 1434 unique abstracts screened, 129 articles underwent full-text review, with 14 meeting criteria for inclusion and full coding. Significant results organized into three main themes: importance of using common definitions; evolution of theory over time with untapped explanatory power; identity as a dynamic construct. DISCUSSION: The current body of knowledge leaves many gaps. These include lack of common definitions, need to apply ongoing theoretical insights to research, and exploration of professional identity as an evolving construct. As we come to understand PIF among medical faculty more fully, twin benefits accrue: (1) Community of practices can be designed deliberately to encourage full participation of all graduate medical education faculty who desire it, and (2) Faculty can more effectively lead trainees in negotiating the ongoing process of PIF across the landscape of professional identities.

Situativity: a family of social cognitive theories for understanding clinical reasoning and diagnostic error.

The diagnostic error crisis suggests a shift in how we view clinical reasoning and may be vital for transforming how we view clinical encounters. Building upon the literature, we propose clinical reasoning and error are context-specific and proceed to advance a family of theories that represent a model outlining the complex interplay of physician, patient, and environmental factors driving clinical reasoning and error. These contemporary social cognitive theories (i.e. embedded cognition, ecological psychology, situated cognition, and distributed cognition) can emphasize the dynamic interactions occurring amongst participants in particular settings. The situational determinants that contribute to diagnostic error are also explored.

Failure Pressures of Dural Repairs in a Porcine Ex Vivo Model: Novel Use of Titanium Clips Versus Tissue Glue.

OBJECTIVE: Endoscopic skull base surgery is advancing, and it is important to have reliable methods to repair the resulting defect. The objective of this study was to determine the failure pressures of 2 commonly used methods to repair large dural defects: collagen matrix underlay with fibrin glue and collagen matrix underlay with polyethylene glue, as well as a novel repair method: fascia lata with nonpenetrating titanium vascular clips. METHODS: The failure pressure of the 3 dural repairs was determined in a closed testing apparatus. Defects in porcine dura were created and collagen matrix grafts were used as an underlay followed by either fibrin glue (FG/CMG) or polyethylene glycol glue (PEG/CMG). A third condition using a segment of fascia lata was positioned flush with the edges of the dural defect and secured with titanium clips (TC/FL). Saline was infused to simulate increasing intracranial pressure (ICP) applied to the undersurface of the grafts until the repairs failed. RESULTS: The mean failure pressure of the PEG/CMG repair was 34.506 ± 14.822 cm H2O, FG/CMG was 12.413 ± 5.114 cm H2O, and TC/FL was 8.330 ± 3.483 cm H2O. There were statistically significant differences in mean failure pressures among the 3 repair methods. CONCLUSION: In this ex vivo model comparing skull base repairs' ability to withstand cerebrospinal fluid leak, the repairs that utilized PEG/CMG tolerated the greatest amount of pressure and was the only repair that exceeded normal physiologic ICP's. Repair methods utilizing glues generally tolerated higher pressures compared to the novel repair using clips alone.

Construct validity of a low-cost medium-fidelity endoscopic sinus surgery simulation model.

OBJECTIVE: Assess construct validity of a low-cost medium-fidelity silicone injection molded model task trainer for endoscopic sinus surgery (ESS) training. METHODS: Fellowship-trained rhinologists, otolaryngology attendings, and otolaryngology residents at various levels of training performed sinus endoscopy and seven procedures on the model. Construct validity was evaluated by comparing novice to various levels of experienced performance using a validated checklist. RESULTS: Thirty-two subjects participated in this study. Otolaryngology attendings and postgraduate year (PGY) 3 to 5 otolaryngology residents significantly outperformed PGY 1 to 2 otolaryngology residents on most tasks in the task-specific checklist. CONCLUSIONS: This study demonstrated the construct validity of the low-cost medium-fidelity ESS model. LEVEL OF EVIDENCE: NA Laryngoscope, 129:1505-1509, 2019.

Assessing Mentorship Experiences of Faculty at a Military Academic Center: Challenge and Opportunity.

OBJECTIVES: Mentor relationships are a key component of professional development within academic medicine. To date, there are no investigations into the prevalence and effects of mentor relationships within military academic medicine. This quality improvement initiative aimed to establish the prevalence and effects of mentorship, including whether sex differences exist among faculty at a military academic center, the San Antonio Uniformed Services Health Education Consortium, and identify opportunities to improve faculty development efforts for mentorship to benefit faculty at this institution. METHODS: A 17-item survey was developed using an iterative process. Using the SurveyMonkey platform, the survey was distributed to each faculty member within the 33 Accreditation Council for Graduate Medical Education-accredited programs. RESULTS: A total of 104 responses (26%) were received from 393 total faculty members, including 48 Air Force, 45 Army, 3 Navy, and 8 Contractor/Government Service respondents. Thirty-four respondents were women (33%) and 70 were men (67%). Only 42% of faculty reported currently having a mentor. Thirty-nine respondents (38%; 44% men and 27% women) received formal mentorship at their first staff physician position after residency training. Mentorship helped respondents the most in the areas of clinical skills, understanding departmental/institutional culture, professionalism/officership, academic promotion/advancement, and clarification of priorities/goals. When asked whether more effective mentorship would affect their own decision to remain on active-duty military service, 14% responded "yes" and 28% responded "possibly." CONCLUSIONS: Increased mentorship has the potential to positively affect career development in military academic military medicine. Results from this study affirm previous reports that effective mentorship potentially represents a powerful tool for faculty retention. Future study should include other military medical academic centers to assess the generalizability of these results across US military medicine.

Evidence-based dosing of maintenance subcutaneous immunotherapy: a contemporary review of state-of-the-art practice.

BACKGROUND: Subcutaneous immunotherapy is an effective allergy treatment only if properly dosed. In this article we review the data on the probable effective dose range for subcutaneous immunotherapy and convert the recommended doses into a clinically relevant format. METHODS: A comprehensive literature search of dose-response subcutaneous immunotherapy studies was done of EBM databases, Medline database, PreMedline, and the National Guideline Clearinghouse for the period 1980-2016. Recommended doses were converted to the volume of allergen extract that should be added to a 5-mL maintenance vial. RESULTS: A safe and effective dose for subcutaneous immunotherapy is likely 5-20 µg of major allergen per injection. A 0.5-mL injection from a 5-mL maintenance vial containing 0.2 mL of manufacturer's extract of each allergen should reach the lower end of the probable effective dose range for most allergens. A larger volume of extract is required to reach that range when treatment includes cat, dog, or only 1 dust mite. Increasing beyond the commonly prescribed 0.2 mL of manufacturer's extract added to a 5-mL treatment vial is reasonable for nearly all allergens to achieve a maintenance dose higher in the probable effective dose range. CONCLUSION: Current otolaryngic allergy practice usually escalates patients to 0.5-mL injections from 5-mL maintenance vials containing 0.2 mL of manufacturer's extract of each allergen. With the main exceptions of cat and dog, those injections administered 1 or 2 times per month likely provide an efficacious dose of allergen and are consistent with published guidelines. A larger volume of extract should be considered in certain clinical situations.

Randomized Controlled Trial Examining the Effects of Balloon Catheter Dilation on "Sinus Pressure" / Barometric Headaches.

Objective To determine if balloon catheter dilation of sinus ostia affects the severity or frequency of headache among patients who have barometric pressure-related "sinus" headache. Study Design Prospective single-blinded randomized controlled trial. Setting Tertiary care medical center. Subjects and Methods Subjects with a diagnosis of sinus pressure headache without evidence of mucosal thickening on computed tomography were recruited. Subjects were blinded and randomized to undergo balloon dilation of affected sinus ostia (active treatment) or balloon dilation in the nasal cavity (placebo). Two balloon devices were utilized (Acclarent and Entellus) and outcomes compared. Subjects were followed with pre- and postprocedure SNOT-22 scores (Sinonasal Outcome Test-22), HIT-6 scores (Headache Impact Test-6), and medication utilization logs for 6 months. Results There was no statistically significant difference in SNOT-22 or HIT-6 scores between the arms at any time point. However, both arms experienced statistically and clinically significant decreases in SNOT-22 and HIT-6 scores from preprocedure to 6 months postprocedure. There was no statistically significant difference in SNOT-22 or HIT-6 score reductions between the Entellus and Acclarent devices. There was no statistically significant difference in medication utilization between the groups at any time point. Conclusions Subjects with sinus pressure headache without evidence of mucosal thickening on computed tomography had no significant difference in outcomes between active treatment (balloon dilation of sinus ostia) and placebo (nasal dilation). Further study on the etiology and effective treatment of barometric pressure / "sinus" headache is needed.

Workforce Considerations, Training, and Diseases in the Middle East.

Evaluating and providing global health assistance, humanitarian aid, and medical missions to Middle Eastern countries can be rewarding and challenging. A broad spectrum of financial capabilities supports effective health care delivery and infrastructure. Middle East tension can make obtaining a visa difficult. Personal safety considerations may hinder efforts to develop and carry out clinical and educational programs. Several Middle East countries have sophisticated and modern health care systems. Medical education and specialty training compares with that of Western medicine. The Middle East has a proud heritage as the foundation of many fundamental and modern medical and surgical principles.

An ergonomic assessment of operating table and surgical stool heights for seated otolaryngology procedures.

BACKGROUND: Musculoskeletal injuries, such as neck and back pain, during a surgeon's career are common. However, studies on ergonomics are limited with regard to seated otolaryngologic procedures. Key elements of an ergonomic operating environment include the height of operating tables and surgical chairs. Surgeons benefit from proper support and positioning to prevent musculoskeletal injuries and reduce occupational risk. OBJECTIVE: The purpose of this study was to evaluate operating table and surgical seat heights, and determine whether adjustments can be made for various surgeon physiques. METHODS: Operating tables and surgical seat dimensions were measured at local hospitals, and the information was complemented by an online search of other models. RESULTS: Five unique operating tables and five unique surgical stools were identified, both in the local hospital and in a search on the Internet. Of available tables, the greatest range was 63.5-124.5 cm, which reaches above the maximum suggested working height of 76.2 cm. The surgical stool with the widest range was adjustable from heights of 50.8-72.4 cm. This combination of operative table and surgical stool provided the greatest range of heights. CONCLUSION: Of the available tables and stools measured, the combination of surgical table with a range of 63.5-125.7 cm and surgical stool with a range of 50.8-72.4 cm provided the greatest versatility for diverse physician heights. In ergonomic terms, this combination may reduce physical fatigue and create a potentially safer working environment for seated surgeons.

Balloon dilation of sinus ostia in the Department of Defense: Diagnoses, actual indications, and outcomes.

OBJECTIVES/HYPOTHESIS: To determine the primary diagnoses for which balloon catheter dilation (BCD) of sinus ostia is being employed in a profit-blind health care system, the Department of Defense. STUDY DESIGN: Retrospective chart review. METHODS: From January 1, 2011 to December 31, 2013, 319 consecutive patient charts were reviewed for International Classification of Diseases, Ninth Edition (ICD-9) diagnoses, presence of chronic rhinosinusitis (CRS) defined by the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS), preoperative Lund-Mackay scores, nasal endoscopy findings, sinuses dilated, postoperative outcomes, and complications. RESULTS: Of the 319 patients identified, 217 had sufficient documentation to be included. A CRS ICD-9 code was applied in 182 of 217 (83.9%) and recurrent acute rhinosinusitis in 12 of 217 (5.6%). Only 50.5% of CRS patient charts met criteria using EPOS guidelines. In contrast, 39.6% met the ICD-9 criteria for atypical facial pain. Patients with Lund-Mackay scores ≤ 4 were reviewed for number of sinuses dilated. Eighty-eight of 123 patients (71.5%) had sinuses dilated that were free from opacification/mucosal edema on preoperative imaging. CONCLUSIONS: Balloon dilation of sinus ostia has an expanding role in treating sinus disease. In the studied population, BCD is often utilized for alternate indications for which there is currently no evidence of efficacy. Future studies are needed to evaluate the efficacy of this technology in treating these alternate indications. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:544-549, 2017.

Fabrication and validation of a low-cost, medium-fidelity silicone injection molded endoscopic sinus surgery simulation model.

OBJECTIVES/HYPOTHESIS: Develop a low-cost, medium-fidelity model for education in endoscopic sinus surgery techniques. Establish face and content validity of the model based on the feedback of otolaryngology faculty including fellowship-trained rhinologists. STUDY DESIGN: Survey. METHODS: A novel silicone injection molded sinus model was constructed. Three fellowship-trained rhinologists and four general otolaryngologists were recruited to perform seven tasks and provide feedback of the model's performance via a 22-question Likert survey. RESULTS: Those surveyed strongly agreed the sinus model is useful for basic endoscopic skill acquisition such as camera skills (86%), hand-eye coordination (100%), nasal endoscopy skills (100%). Ratings of the model for training the specific tasks were consistently high. Neutral or lower were received for inferior turbinoplasty (14%), frontal balloon task (14%), understanding the ethmoid bulla (29%), and advanced sinus techniques (57%). All faculty strongly agreed they would be interested in using the model to train residents. CONCLUSIONS: Simulation models have proven efficacy in endoscopic skill and procedural training. The group developed a novel low-cost, medium-fidelity sinus training model utilizing three-dimensional modeling and printing. Testing of this model revealed high ratings for both face and construct validity for a range of endoscopic procedures. Strong interest in using this model for resident training was unanimous among all survey participants. LEVEL OF EVIDENCE: NA Laryngoscope, 127:781-786, 2017.

Failure pressures after repairs of 2-cm × 2.5-cm rhinologic dural defects in a porcine ex vivo model.

BACKGROUND: The objective of this study was to determine failure pressures of 6 rhinologic repair techniques of large skull base/dural defects in a controlled, ex vivo model. METHODS: Failure pressures of 6 dural repairs in a porcine model were studied using a closed testing apparatus; 24-mm × 19-mm dural defects were created; 40-mm × 34-mm grafts composed of porcine Duragen (Integra), fascia lata, and Biodesign (Cook) were used either with or without Tisseel (Baxter International Inc.) to create 6 repairs: Duragen/no glue (D/NG), Duragen/Tisseel (D/T), fascia lata/no glue (FL/NG), fascia lata/Tisseel (FL/T), Biodesign/no glue (B/NG), and Biodesign/Tisseel (B/T). Saline was infused at 30 mL/hour, applying even force to the underside of the graft until repair failure. Five trials were performed per repair type for a total of 30 repairs. RESULTS: Mean failure pressures were as follows: D/NG 1.361 ± 0.169 cmH2 O; D/T 9.127 ± 1.805 cmH2 O; FL/NG 0.200 ± 0.109 cmH2 O; FL/T 7.833 ± 2.657 cmH2 O; B/NG 0.299 ± 0.109 cmH2 O; and B/T 2.67 ± 0.619 cmH2 O. There were statistically significant differences between glued (Tisseel) and non-glued repairs for each repair category (p < 0.05). CONCLUSION: All glued repairs performed better than non-glued repairs. Both D/T and FL/T repairs performed better than B/T repairs. No repair tolerated pressures throughout the full range of adult supine intracranial pressure.

Gluten sensitivity: fact or fashion statement?

PURPOSE OF REVIEW: In recent years, the concern over food sensitivities in general and gluten intolerance in particular has sharply increased. Patients and medical providers are awash in various claims about the potential implications of including or excluding gluten from the diet. RECENT FINDINGS: Three main conditions are described with respect to gluten: wheat allergy, celiac disease, and nonceliac gluten sensitivity (NCGS). Wheat allergy is a type 1 hypersensitivity reaction to nongluten proteins within wheat. Celiac disease is an autoimmune reaction to the gluten protein resulting in damage to the small intestine with genetic associations. NCGS is a diagnosis of exclusion and, to date, no biomarkers have been identified for this condition. SUMMARY: When evaluating and treating patients with potential reactions to gluten, it is important to distinguish among wheat allergy, celiac disease, and NCGS. Each condition has distinct dietary and treatment implications.

International Consensus Statement on Allergy and Rhinology: Rhinosinusitis.

BACKGROUND: The body of knowledge regarding rhinosinusitis(RS) continues to expand, with rapid growth in number of publications, yet substantial variability in the quality of those presentations. In an effort to both consolidate and critically appraise this information, rhinologic experts from around the world have produced the International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR:RS). METHODS: Evidence-based reviews with recommendations(EBRRs) were developed for scores of topics, using previously reported methodology. Where existing evidence was insufficient for an EBRR, an evidence-based review (EBR)was produced. The sections were then synthesized and the entire manuscript was then reviewed by all authors for consensus. RESULTS: The resulting ICAR:RS document addresses multiple topics in RS, including acute RS (ARS), chronic RS (CRS)with and without nasal polyps (CRSwNP and CRSsNP), recurrent acute RS (RARS), acute exacerbation of CRS (AECRS), and pediatric RS. CONCLUSION: As a critical review of the RS literature, ICAR:RS provides a thorough review of pathophysiology and evidence-based recommendations for medical and surgical treatment. It also demonstrates the significant gaps in our understanding of the pathophysiology and optimal management of RS. Too often the foundation upon which these recommendations are based is comprised of lower level evidence. It is our hope that this summary of the evidence in RS will point out where additional research efforts may be directed.
