The impact of simulation-based training on medical students' whole blood transfusion abilities.

BACKGROUND: Whole blood transfusion has been found to increase the likelihood of patient survival within both military and civilian medicine contexts. However, no whole blood transfusion training curriculum currently exists within undergraduate or graduate medical education in the United States. The purpose of our study was to: (1) determine the impact of simulation-based training on medical students' abilities to conduct whole blood transfusions; and (2) determine the impact of simulation-based training on medical students' confidence in conducting whole blood transfusions. STUDY DESIGN AND METHODS: We assessed 157 third-year military medical students' ability to conduct whole blood transfusion before and after Operation Gunpowder, a 2-day high-fidelity prolonged casualty care simulation. We conducted a paired samples t-test to compare the students' pre- and post-simulation performance scores as well as self-reported confidence and stress ratings. RESULTS: There was a significant difference in students' scores at the beginning of the course (M = 20.469, SD 6.40675) compared to their scores at the end of the course (M = 30.361, SD = 2.10053); t(155) = -18.833, p < .001. The effect size for this analysis (d = 6.56) was large. There was a significant difference (p < .001) between the pre- and post-ratings for all self-reported confidence and stress survey items. DISCUSSION: Our results suggest that simulation-based training is an effective means of training medical students to conduct whole blood transfusiontraining in a limited resource simulated environment where blood inventories may be limited.

Serious bacterial infection risk in recently immunized febrile infants in the emergency department.

STUDY OBJECTIVES: Fever following immunizations is a common presenting chiefcomplaint among infants. The 2021 American Academy of Pediatrics (AAP) febrile infant clinical practice guidelines exclude recently immunized (RI) infants. This is a challenge for clinicians in the management of the febrile RI young infant. The objective of this study was to assess the prevalence of SBI in RI febrile young infants between 6 and 12 weeks of age. METHODS: This was a retrospective chart review of infants 6-12 weeks who presented with a fever ≥38 °C to two U.S. military academic Emergency Departments over a four-year period. Infants were considered recently immunized (RI) if they had received immunizations in the preceding 72 h prior to evaluation and not recently immunized (NRI) if they had not received immunizations during this time period. The primary outcome was prevalence of serious bacterial infection (SBI) further delineated into invasive-bacterial infection (IBI) and non-invasive bacterial infection (non-IBI) based on culture and/or radiograph reports. RESULTS: Of the 508 febrile infants identified, 114 had received recent immunizations in the preceding 72 h. The overall prevalence of SBI was 11.4% (95% CI = 8.9-14.6) in our study population. The prevalence of SBI in NRI infants was 13.7% (95% CI = 10.6-17.6) compared to 3.5% (95% CI = 1.1-9.3) in RI infants. The relative risk of SBI in the setting of recent immunizations was 0.3 (95% CI = 0.1-0.7). There were no cases of invasive-bacterial infections (IBI) in the RI group with all but one of the SBI being urinary tract infections (UTI). The single non-UTI was a case of pneumonia in an infant who presented with respiratory symptoms within 24 h of immunizations. CONCLUSION: The risk of IBI (meningitis or bacteremia) in RI infants aged 6 to 12 weeks is low. Non-IBI within the first 24 h following immunization was significantly lower than in febrile NRI infants. UTIs remain a risk in the RI population and investigation with urinalysis and urine culture should be encouraged. Shared decision making with families guide a less invasive approach to the care of these children. Future research utilizing a large prospective multi-center data registry would aid in further defining the risk of both IBI and non-IBI among RI infants.

Case Report: Not All Genital Ulcers Are Herpetic.

BACKGROUND: The most common cause of genital lesions is herpes simplex virus (HSV) (Pediatr Dermatol. 2012;29:147-153). However, in children and adolescents who are not sexually active, several other causes need to be considered. CASE: A 13-year-old adolescent girl presented to the emergency department with genital lesions. A gynecologist was consulted at time of presentation for concerns of a primary HSV infection and concurred. Final HSV and sexually transmitted infection testing were subsequently negative. At outpatient follow-up, a child abuse pediatrician made the diagnosis of aphthous genital ulcers (AGUs). Awareness of the diagnosis of AGUs is important because alternate diagnoses such as HSV could imply child abuse. It is critical to include AGUs in the differential diagnosis and to provide the appropriate referrals.

Inpatient Treatment after Multi-Dose Racemic Epinephrine for Croup in the Emergency Department.

BACKGROUND: Emergency department (ED) discharge is safe when croup-related stridor has resolved after corticosteroids and a single dose of racemic epinephrine (RE). Little evidence supports the traditional practice of hospital admission after ≥ 2 doses of RE. OBJECTIVE: Our aim was to describe the frequency and timing of clinically important inpatient interventions after ≥ 2 ED RE doses. METHODS: We identified patients hospitalized for croup after ED treatment with corticosteroids and ≥2 doses of RE. We compared asymptomatic (admitted solely on the number of RE doses) and symptomatic (admitted due to disease severity) groups with regard to inpatient RE administration, supplemental oxygen, helium-oxygen mixture (heliox) therapy, intubation, or transfer to a higher level of care, time to hospital discharge, and revisit and readmission rates within 48 h of discharge. RESULTS: Of 200 subjects admitted after ≥ 2 ED RE doses, 72 (36%) received clinically important inpatient interventions: RE (n = 68 [34%]), heliox (n = 9 [5%]), and supplemental oxygen (n = 4 [2%]). Of patients who received inpatient RE, 53% received only 1 dose. No patients underwent intubation or transfer to higher level of care. The 112 asymptomatic patients had fewer interventions (14% vs. 63%; p < 0.001) and shorter hospital durations (14.5 vs. 22 h; p < 0.001). Only 14% of the asymptomatic group received RE, with 75% receiving a single dose. There were no differences in revisit and readmission rates. CONCLUSIONS: Inpatient interventions after ≥ 2 ED doses of RE for croup were infrequent, most commonly RE administration. Most patients asymptomatic upon admission require 0-1 inpatient RE doses and may be candidates for outpatient management.

Peer Teachers' Professional Identity Development During a Prehospital Simulation: A Grounded Theory Study.

INTRODUCTION: Peer teachers have been found to be effective instructors during simulation-based education. However, there is a lack of research regarding their professional identity development throughout the course of the teaching activity. The purpose of this qualitative study, therefore, was to develop a framework to illustrate how peer teachers develop as educators during a prehospital simulation. METHODS: The participants in our study were 9 second-year medical students serving as peer teachers during a multiday prehospital simulation. We selected the grounded theory tradition of qualitative research to investigate the peer teachers' professional identity development. Our research team interviewed each participant twice during the simulation. We then used open and axial coding to analyze the interview data. We organized these codes into categories and determined connections between each category to construct our grounded theory framework. RESULTS: This framework described how the peer teachers progressed through 4 stages: 1) eager excitement, 2) grounded by challenges, 3) overcoming challenges, and 4) professional identity formation. CONCLUSION: Our results revealed that simulation-based education can serve as valuable learning environment not only for medical students, but also for peer teachers. Understanding their progressive development during the simulation will help medical educators focus on maximizing the peer teachers' growth and development during simulation.

Civilian and Military Medical School Graduates' Readiness for Deployment: Areas of Strength and Opportunities for Growth.

INTRODUCTION: Past research has examined civilian and military medical schools' preparation of physicians for their first deployment. Most recently, our research team conducted a large-scale survey comparing physicians' perceptions of their readiness for their first deployment. Our results revealed that military medical school graduates felt significantly more prepared for deployment by medical school than civilian medical school graduates. In order to further investigate these results and deepen our understanding of the two pathways' preparation of military physicians, this study analyzed the open-ended responses in the survey using a qualitative research design. MATERIALS AND METHODS: We used a descriptive phenomenological design to analyze 451 participants' open-ended responses on the survey. After becoming familiar with the data, we coded the participants' responses for meaningful statements. We organized these codes into major categories, which became the themes of our study. Finally, we labeled each of these themes to reflect the participants' perceptions of how medical school prepared them for deployment. RESULTS: Four themes emerged from our data analysis: (1) Civilian medical school equipped graduates with soft skills and medical knowledge for their first deployment; (2) Civilian medical school may not have adequately prepared graduates to practice medicine in an austere environment to include the officership challenges of deployment; (3) Military medical school prepared graduates to navigate the medical practice and operational aspects of their first deployment; and (4) Military medical school may not have adequately prepared graduates for the realism of their first deployment. CONCLUSIONS: Our study provided insight into the strengths and areas for growth in each medical school pathway for military medical officers. These results may be used to enhance military medical training regardless of accession pathway and increase the readiness of military physicians for future large-scale conflicts.

Gender and Mentorship in Military Medicine: A Survey Study.

INTRODUCTION: Mentorship is essential for professional development and advancement within the military. In civilian medicine, the intersection between gender and mentorship holds important implications for research opportunities, academic success, and career progression. However, the intersection of gender and mentorship has not yet been explored within the field of military medicine. The purpose of this study, therefore, was to investigate the role of gender in mentorship within the field of military medicine. MATERIALS AND METHODS: We investigated gender and mentorship within military medicine by developing and distributing a 16-item Likert survey to active-duty military physicians. We used the Chi-squared test of independence and the independent samples t-test to examine the role of gender in mentorship among the 16 questions. RESULTS: The male respondents reported more same-gender mentors than females (male [M]: 61.9% vs. female [F]: 33.0%), whereas the female respondents had significantly more mentors of the opposite gender than males (M: 12.4% vs. F: 47.3%). A higher proportion of males indicated no preference compared to females. Conversely, a significant preference for a same-sex mentor was expressed by female respondents compared to male respondents (M: 5.2% vs. F: 30.1%). In contrast, female respondents considered having a mentor more important than their male counterparts (t(206) = -2.26, P = .012, F: 3.86 vs. M: 3.57). Both male and female respondents had significantly more female mentees ($\chi _{\left( 1 \right)}^2$ = 12.92, P < .001, Cramer's V = 0.254). CONCLUSIONS: While the female participants in our study preferred female mentors, the male participants had more same-gender mentors than the female participants. In addition, more females reported that they did not have the time to be mentored. Our results, therefore, suggest that training males to be better mentors to females and providing accessible mentorship training to females may promote equitable career development within military medicine.

The Relationship between the Military Medical Officer and Commanding Officer: Implications for Education and Training.

INTRODUCTION: A successful working relationship between the Military Medical Officer (MMO) and Commanding Officer (CO) is critical for mission success. However, there is a gap in the professional literature outlining evidence-based practices for teaching early career MMOs how to strategically develop this relationship. The purpose of this study, therefore, was to explore our participants' perceptions of how MMOs can foster a positive and productive working relationship with the CO. MATERIALS AND METHODS: We leveraged interpretive phenomenological design to interview 16 seasoned military physicians with extensive operational experience. We transcribed and coded each interview. Our research team determined how to organize these codes into major categories, which served as our study's themes. RESULTS: The participants described three key elements for developing a good working relationship between the CO and MMO: (1) mission-focused communication; (2) active and physical presence; and (3) expert/advisor role fulfillment. The MMO should communicate with the CO in an understandable and mission-focused manner. The MMO should likewise be present within day-to-day operations and should establish their officership during mission planning. The MMO should fulfill their role as a subject matter expert, yet advisor, to the CO. CONCLUSIONS: Communication, presence, and role fulfillment are essential elements for optimizing the MMO-CO working relationship. Learning these roles during medical school may enhance early career physicians' mission readiness.

Expectant Casualty Care Training Needs for Future Conflicts.

INTRODUCT ION: The demands of future large-scale combat operations may require medics and corpsmen to increasingly perform expectant casualty care (ECC). However, no detailed guidelines currently exist for providing ECC within military medicine. To guide the development of education and training guidelines and advance team training of both medics and non-medics, an in-depth understanding is first needed regarding caregivers' experiences providing ECC in recent conflicts as well as perceived training gaps. Therefore, this study explored the experiences of medics and physicians providing ECC and investigated their perceptions of training needs in this area for future conflicts characterized by large-scale combat operations and prolonged casualty care operational settings. MATERIALS AND METHODS: We conducted an engaged qualitative phenomenological study to explore ECC training needs for future conflicts. We interviewed 9 senior health care professionals (medics and physicians) who had extensive combat and deployment experiences and served primarily in the Role 1 environment. The interviews averaged 45 min each and were conducted via phone. To analyze this interview data, we reviewed the interview transcripts and then noted terms, phrases, and concepts within the interview transcripts that we found to be salient to answering the research question. Our team then met to review these codes and grouped them into categories. These categories served as the themes of this study that illustrated the participants' perceptions and experiences. RESULTS: Five themes emerged from our data: (1) There is a current gap in ECC training for enlisted Role 1 caregivers throughout the military; (2) ECC training is needed to shift organizational culture; (3) ECC training should be comprehensive; (4) ECC training should be deliberate; and (5) Time is the greatest challenge to implementing ECC training. Our participants noted that developing guidelines and filling training gaps is not only critical for preparing Role 1 providers for effective and ethical military medical decision-making but also for addressing death and dying on the battlefield and building moral resilience across the medical corps. CONCLUSION: Our results provide direction for development of ECC clinical guidance and collective team training recommendations. Following these guidelines may increase life-saving capabilities on the far-forward battlefield and equip medical directors and medics to provide ethical and compassionate care to those who cannot be saved in the setting of limited resources and evacuation opportunities.

Improved Casualty Depiction System for Simulated Mass Casualty Exercises.

INTRODUCTION: Assessing military medical teams' ability to respond to large-scale mass casualty (MASCAL) events has become a priority in preparing for future conflicts. MASCAL exercises rely on large numbers of simulated patients with limited medical training. Role-players must be appropriately prepared to ensure that medical exercises adequately assess the expected capabilities of military medical units. The Uniformed Services University of the Health Sciences (USUHS) has evaluated future military providers for decades using a large-scale, multiday, immersive simulation called Bushmaster. Despite a robust casualty training system, the fidelity of the portrayals remained limited. MATERIALS AND METHODS: Through collaboration with national military medical experts, a comprehensive casualty depiction system was developed. This system relied on structured casualty cards linked to time-based illness scripts. Structured casualty cards included an appropriate balance of disease non-battle injuries and trauma, included multipatient presentations based on shared events (i.e., multiple injured personnel due to an aircraft crash), normal and pathologic combat stress, population/unit considerations, requirements for different roles within the medical unit, and expected clinical outcomes. Illness scripts, supplemented by video guides, included time-based courses of illness/injury and prescribed responses to different typical treatments. This system was piloted during an annual MASCAL exercise (Operation Bushmaster) at USUHS. Clinical faculty were queried on the fidelity of this new system while role-players were evaluated on feasibility. RESULTS: Three hundred casualty cards linked to 49 illness scripts were created, peer-reviewed, and piloted at Bushmaster. A total of 170 military members with limited medical training portrayed simulated patients utilizing the new casualty depiction system. Clinical faculty members strongly agreed that the improved casualty depiction system improved the realism of individual patient presentations (96%). Eighty-three percent of role-players strongly agreed that the casualty depiction system was easy to understand. CONCLUSIONS: This improved casualty depiction system was a feasible approach to enhance the fidelity of a MASCAL exercise. It has since been shared with military medical units around the globe to assist with their MASCAL exercises, making future multisite evaluations of this casualty depiction system possible.

"Not for the Faint of Heart": First-year Military Medical Students' Professional Identity Formation During the Innovative Patient Experience at Operation Bushmaster.

INTRODUCTION: The role of a military medical officer (MMO) is complex. Therefore, it is essential that military medical students formulate their professional identity early on in medical school in order to prepare them for their first deployment. At the Uniformed Services University, students are challenged to progressively develop their professional identity through yearly high-fidelity military medical field practicums (MFPs). One of these MFPs, Operation Bushmaster, consists of an innovative "Patient Experience" in which first-year medical students portray patients cared for by fourth-year medical students in a simulated operational environment. The purpose of this qualitative study was to examine how participating in the Patient Experience impacted first-year medical students' professional identity formation. MATERIALS AND METHODS: Our research team used a phenomenological, qualitative research design to analyze the end-of-course reflection papers of 175 first-year military medical students who participated in the Patient Experience during Operation Bushmaster. Our research team members individually coded each student's reflection paper and then came to consensus on how to organize these codes into themes and subthemes. RESULTS: Two themes and seven subthemes emerged from the data regarding the first-year medical students' understanding of the MMO: (1) multiple roles of the MMO (educator, leader, diplomat, and advisor) and (2) role of the MMO in the operational environment (navigates hazardous environment, adaptability, and position within health care team). As they participated in the Patient Experience, the first-year medical students not only recognized the complexity of the MMO's multiple roles within the operational environment but also envisioned themselves in these roles. CONCLUSIONS: The Patient Experience provided first-year medical students with a unique opportunity to formulate their professional identity as they portrayed patients during Operation Bushmaster. This study's results hold implications for both military and civilian medical schools regarding the benefits of innovative military MFPs for professional identity formation in junior medical students, preparing them early on in medical school for their first deployment.

What to know about 2.0: Revisions to the pediatric emergency medicine milestones.

Introduction: The Accreditation Council for Graduate Medical Education (ACGME) adopted educational milestones for trainee assessment in 2013, as a key component of the Next Accreditation System. Two years later, the ACGME, American Board of Pediatrics (ABP), and American Board of Emergency Medicine (ABEM) collaborated to create specialty-specific subcompetencies in pediatric emergency medicine (PEM). Since that time, emerging data have demonstrated the need to revise specialty milestones. Consequently, the ACGME summoned a working group to revise the original PEM milestones. Methods: The PEM Milestones 2.0 Working Group convened in April 2021, comprising diverse representation from ACGME staff, PEM and EM attendings, PEM fellowship program directors, PEM fellows, and community members, overseen by the ACGME's vice president for milestones development. The group met virtually six times over 3 months, with concurrent independent and subgroup work, to draft the PEM Milestones 2.0 and supplemental guide. Results: The working group's revisions generated concise descriptions of behavioral anchors to define skill acquisition more accurately; attention to the transition from residency to fellowship training; incorporation of harmonized milestones for non-patient care and non-medical knowledge domains; and increased emphasis on diversity, equity, and inclusion. A supplemental guide was also designed to aid programs in designing programmatic assessment related to specialty-specific milestones. Conclusions: The PEM Milestones 2.0 provide an updated, specialty-specific framework to guide the development and assessment of PEM fellows and training programs. Future work may focus on faculty and learner development, advancing validity evidence, strengthening content expertise, and integrating milestones with specialty-specific entrustable professional activities.

The Military Medical Officer's Current-Day Professional Identity: An Enhanced Model.

BACKGROUND: As the landscapes of war have evolved, so too has the role of the military medical officer (MMO). Colonel (Retired) Barry Wolcott developed a "vector" model in the 1990s, illustrating the dual professional role of the MMO. Since then, propelled by the War on Terror, MMOs have adapted to treating patients in volatile, uncertain, complex, and ambiguous operational environments. This study, therefore, aimed to explore modern-day aspects of the MMO's role in order to enhance Wolcott's depiction of the MMO's professional identity in contemporary operational environments. MATERIALS AND METHODS: We used the qualitative phenomenological tradition to design our study. We interviewed military physicians from a variety of specialties in order to explore their experiences and professional identity as MMOs. Our research team then coded each of these interview transcripts. We organized these codes into categories, which served as the themes of our study. RESULTS: The following themes emerged from our data regarding the role of the MMO in the operational environment: Primary roles (officer, physician, educator, and diplomat) and aptitudes (innovation, advocacy, cultural competency, and leadership). The MMO's roles as officer and physician often intersect, with dual foci on the mission and the patient. The MMO also serves as an educator to medics and line officers. In addition, they act as diplomats both outside and within the military. Within each of these primary roles, the MMO innovatively prepares for future landscapes of war and advocates for both the individual warfighter and the unit/command. Finally, the MMO navigates both foreign and internal cultural differences and demonstrates leadership in enabling the military's mission. CONCLUSIONS: The role of the MMO is complex and multifaceted. The recognition of the contemporary MMO's unique skill set is essential for the effective education and training of future military health care leaders. The value of capitalizing on this unique skill set has been demonstrated in recent civ-mil responses. Because their intricate skill set is specialized for the operational environment, long-term retention of MMOs is key to force readiness.

The Impact of High-fidelity Simulations on Medical Student Readiness.

INTRODUCTION: Simulation is a key aspect of the military unique curriculum at the Uniformed Services University (USU). The Department of Military and Emergency Medicine conducts rigorous high-fidelity simulations for military medical students during each year of their medical school training: Patient Experience (first year), Advanced Combat Medical Experience (second year), Operation Gunpowder (third year), and Operation Bushmaster (fourth year). There is currently a gap in the professional literature regarding students' progression through each of these simulations. This study, therefore, explores the experiences of military medical students at USU in order to understand how they learn and develop as they progress through these high-fidelity simulations. MATERIALS AND METHODS: Using a grounded theory approach to qualitative research design, we analyzed qualitative data from 400 military medical students across all four years of military school who participated in the four high-fidelity simulations during 2021-2022. Our research team used open and axial coding to categorize the data and to make connections between each of these categories, which we articulated in a theoretical framework and illustrated in a consequential matrix. This research was approved by the Institutional Review Board at USU. RESULTS: During Patient Experience, the first-year medical students described the stress, chaos, and lack of resources that military physicians face as they experienced the realism of the operational environment. Later at Advanced Combat Medical Experience, the second-year medical students practiced their medical skills hands-on for the first time in the simulated stressful operational environment. As a result, they gained confidence and began to formulate their professional identity. Next, at Operation Gunpowder, the third-year medical students advanced to more complex tactical field care as they performed prolonged casualty care, forward resuscitative care, forward resuscitative surgical care, and en route care as a team, often revealing gaps in their knowledge that needed to be filled. During the capstone simulation, Operation Bushmaster, the fourth-year medical students closed these gaps and solidified their professional identity as leaders and physicians, culminating in a strong confidence regarding their readiness for their first deployment. CONCLUSIONS: Each of the four high-fidelity simulations impacted the students in unique ways as they were incrementally challenged to practice and build upon their knowledge, skills, and abilities related to combat casualty care, teamwork, and leadership in the operational environment. As they completed each of the simulations, their skills improved, confidence grew, and professional identity solidified. Therefore, completing these rigorous simulations progressively over the course of 4 years of medical school appears to be a vital process and foundation for the deployment readiness of early-career military physicians.

A Comparison of Uniformed Services University and Health Professions Scholarship Program Graduates' First Deployment Readiness.

INTRODUCTION: Military physicians must be prepared to lead health care teams across complex landscapes of war during future small- and large-scale combat operations. This preparation optimally begins in medical school so that early career physicians are fully ready for their first deployment. Past qualitative research has suggested that military physicians who attended civilian medical school are not as well prepared for the operational environment as physicians who attended the Uniformed Services University (USU), our nation's military medical school. However, there is a lack of larger-scale quantitative research comparing the readiness differences between the two medical school pathways. The purpose of this study, therefore, was to quantify any differences in first deployment preparation between students attending USU and civilian medical schools through the Health Professions Scholarship Program (HPSP). MATERIALS AND METHODS: We compared USU and HPSP graduates' first deployment experiences by distributing a 14-item Likert survey to active duty military physicians in the U.S. Army, U.S. Navy, and U.S. Air Force who graduated within the past 10 years from medical school (USU or civilian). RESULTS: The USU graduates rated themselves significantly higher than the HPSP graduates on their readiness for deployment (3.83 vs. 3.24; P < .001); ability to navigate the operational environment (3.59 vs. 2.99; P < .001); confidence in communicating with their commanding officer (3.59 vs. 2.99; P = .002); navigating the combined role as physician and officer (3.33 vs. 2.84; P = .004); leading a health care team (3.94 vs. 3.43; P = .001); preparation by a medical school (3.78 vs. 2.52; P < .001); and overall readiness compared to peers (4.20 vs. 3.49; P < .001). There was no significant difference between the two pathways regarding their stress level at the beginning of deployment (2.74 vs. 2.68; P = .683); clinical preparation (3.94 vs. 3.76; P = .202); and success of first deployment (3.87 vs. 3.91; P = .792). The largest effect size of the difference between the two pathways was noted on the question "How well did medical school prepare you for your first deployment" (Cohen's d = 1.02). CONCLUSIONS: While both groups believed that they were prepared for their first deployment, USU graduates consistently reported being more prepared by medical school for their first deployment than HPSP graduates. To close this readiness gap, supplemental military unique curricula may help to optimize HPSP students' readiness.

Medical Students' Professional Identity Formation During Operation Bushmaster.

INTRODUCTION: The role of the military medical officer is complex, as it encapsulates officer, physician, and leader. Professional identity formation is therefore essential for military medical students and junior military physicians to successfully execute the responsibilities of the military medical officer in their future careers. Because little is known regarding best practices for professional identity formation training for military physicians, this study explored the ways in which medical students conceptualized the complex roles of the military medical officer during a medical field practicum. MATERIALS AND METHODS: Guided by the phenomenological tradition of qualitative research, we interviewed 15 fourth-year medical students twice regarding their understanding of the role of the military medical officer, as they progressed through a 5-day high-fidelity military medical field practicum, Operation Bushmaster. Our research team then analyzed the interview transcripts for emerging themes and patterns, which served as the results of this study. RESULTS: The following themes emerged from the data regarding the participants' conceptualization of the military medical officer: (1) the scope of the role of the military medical officer; (2) the intersecting identities of the military medical officer; and (3) the adaptable role of the military medical officer in an operational environment. As they progressed through the medical field practicum, the participants articulated a clear understanding of the vast and complex nature of the military medical officer's intersecting roles as officer, physician, and leader in austere and often unpredictable environments. At the end of the medical field practicum, the participants expressed confidence in carrying out their roles as military medical officers during their future deployments. CONCLUSIONS: This study provided an in-depth understanding of the participants' conceptualization of the military medical officer. The participants described how the medical field practicum provided them with opportunities to experience first-hand and therefore better understand the roles of the military medical officer while leading a health care team in an operational environment. As a result, high-fidelity medical field practicums like Operation Bushmaster appear to be an effective tool for facilitating professional identity formation.

A Comparison of HPSP and USU Graduates' Preparation for Residency.

INTRODUCTION: Military medical students enter residency through two main pathways: (1) The Uniformed Services University (USU) and (2) the Armed Services Health Professions Scholarship Program (HPSP). The purpose of this study was to compare how these two pathways prepare military medical students for residency. METHODS: We conducted semi-structured interviews with 18 experienced military residency program directors (PDs) in order to explore their perceptions of the preparedness of USU and HPSP graduates. We used a transcendental phenomenological qualitative research design to bracket our biases and guide our data analysis. Our research team coded each of the interview transcripts. We then organized these codes into themes, which served as the results of our study. RESULTS: Five themes emerged from our data regarding the residents' preparedness: (1) Ability to navigate the military culture, (2) understanding of the military's medical mission, (3) clinical preparation, (4) ability to navigate the Military Health System (MHS), and (5) teamwork. The PDs described how USU graduates better understand the military's medical mission and are more easily able to navigate the military culture and the MHS because of their lived experiences during military medical school. They also discussed the various levels of clinical preparation of HPSP graduates, in contrast to the USU graduates' more consistent skills and abilities. Finally, the PDs believed both groups to be strong team players. CONCLUSIONS: USU students were consistently prepared for a strong start to residency because of their military medical school training. HPSP students often experienced a steep learning curve because of the newness of the military culture and MHS.

Operation Bushmaster's Impact on Military Medical Student Deployment Readiness.

INTRODUCTION: Operation Bushmaster is a high-fidelity simulation held for fourth-year medical students at the Uniformed Services University. No past research has examined this multi-day simulation's ability to prepare military medical students for the complexities of their first deployment. This qualitative study, therefore, explored Operation Bushmaster's impact on military medical student deployment readiness. METHODS: We interviewed 19 senior military medical personnel serving as faculty members at Operation Bushmaster during October 2022 in order to explore how Operation Bushmaster prepares students for their first deployment. These interviews were recorded and transcribed. Each research team member then coded the transcripts and came to a consensus on the themes and patterns that emerged from the data. RESULTS: The following themes described the ways in which Operation Bushmaster prepares military medical students for their first deployment: (1) primes them for the stress of the operational environment; (2) teaches them to navigate austere conditions; (3) facilitates their leadership development; and (4) provides them with a deeper understanding of the military's medical mission. CONCLUSION: Operation Bushmaster immerses students in a realistic, stressful operational environment, challenging them to develop an adaptive mindset and efficacious leadership skills that they will utilize during future deployments.

The Impact of Operation Bushmaster on Medical Student Decision-making in a High-Stress, Operational Environment.

INTRODUCTION: Operation Bushmaster is a high-fidelity military medical field practicum for fourth-year medical students at the Uniformed Services University. During Operation Bushmaster, students treat live-actor and mannequin-based simulated patients in wartime scenarios throughout the five-day practicum. This study explored the impact of participating in Operation Bushmaster on students' decision-making in a high-stress, operational environment, a crucial aspect of their future role as military medical officers. MATERIALS AND METHODS: A panel of emergency medicine physician experts used a modified Delphi technique to develop a rubric to evaluate the participants' decision-making abilities under stress. The participants' decision-making was assessed before and after participating in either Operation Bushmaster (control group) or completing asynchronous coursework (experimental group). A paired-samples t-test was conducted to detect any differences between the means of the participants' pre- and posttest scores. This study was approved by the Institutional Review Board at Uniformed Services University #21-13079. RESULTS: A significant difference was detected in the pre- and posttest scores of students who attended Operation Bushmaster (P < .001), while there was no significant difference in the pre- and posttest scores of students who completed online, asynchronous coursework (P = .554). CONCLUSION: Participating in Operation Bushmaster significantly improved the control group participants' medical decision-making under stress. The results of this study confirm the effectiveness of high-fidelity simulation-based education for teaching decision-making skills to military medical students.

Medical Students' Integration of Formative Feedback During Simulation: A Grounded Theory Study.

INTRODUCTION: Formative feedback is critical for trainees' growth and development. However, there is a gap in the professional literature regarding the ways in which formative feedback affects student performance during simulation. This grounded theory study addresses this gap by exploring the ways in which medical students received and integrated ongoing formative feedback throughout a multiday, high-fidelity military medical simulation, Operation Bushmaster. MATERIALS AND METHODS: Our research team interviewed 18 fourth-year medical students in order to investigate how they processed formative feedback during the simulation. Guided by the grounded theory tradition of qualitative research, our research team used open coding and axial coding to categorize the data. We then used selective coding to determine the casual relationships between each of the categories that emerged from the data. These relationships determined our grounded theory framework. RESULTS: Four phases emerged from the data and provided a framework to delineate the process in which students received and integrated formative feedback throughout the simulation: (1) ability to self-assess, (2) self-efficacy, (3) leadership and teamwork, and (4) appreciation of feedback for personal and professional growth. The participants first focused on feedback related to their individual performance but then shifted to a teamwork and leadership mindset. Once they adapted this new mindset, they began to intentionally provide feedback to their peers, increasing their team's performance. At the end of the simulation, the participants recognized the benefits of formative feedback and peer feedback for ongoing professional development throughout their careers, signifying a growth mindset. CONCLUSIONS: This grounded theory study provided a framework for determining how medical students integrated formative feedback during a high-fidelity, multiday medical simulation. Medical educators can use this framework to intentionally guide their formative feedback in order to maximize student learning during simulation.
