Introduction
Need for innovation
Barriers to emergency medicine resident research exist at the individual, program, and departmental levels as recognized by the recent Society for Academic Emergency Medicine (SAEM) 2024 Consensus Conference, Creating a Diverse and Sustainable Emergency Medicine Investigator Pathway [1]. These barriers not only present challenges for the development of a diverse and sustainable research workforce capable of tackling health care’s most complex problems, but also specifically limit graduates from emergency medicine residency programs and their abilities to understand, interpret, and apply research findings in their clinical practice.
Given the demands of clinical residency, residents have difficulty completing the scholarship requirement from the Accreditation Council for Graduate Medical Education (ACGME). Barriers to scholarly projects include lack of interest, time, mentoring, support, and skills [Reference Rothberg2]. Within our emergency medicine program, we found that residents often wait until the final year of residency before conducting a project, limiting the quality of such a project and the opportunity for exposure to research as a potential career path. Further, the administrative burden on the part of residency leadership teams to track the completion of such projects can be quite burdensome. To address these challenges, the Department of Emergency Medicine Resident Leadership Team and Research Division collaborated to develop and implement a novel research program for incoming emergency medicine first-year residents to provide systematic research instruction and research project immersion throughout the first year of residency. We describe this novel, immersive one-year program as a potentially sustainable model for resident research regardless of clinical specialty.
Background
Presently, the ACGME mandates each emergency medicine resident must participate in scholarship by the time of graduation from their residency program [3]. Specifically, it states “the curriculum must advance the residents” knowledge of the basic principles of research, including how research is conducted, evaluated, explained to patients, and applied to patient care [3]. This may include peer-reviewed publications, non-peer-reviewed work including online publications and podcasts, textbook chapters, and/or conference presentations at the local, regional, or national level [3]. Despite this guideline, the implementation, interpretation, and quality of the scholarly project requirement varies considerably among programs [Reference Geyer, Kaji, Katz, Jones and Bebarta4]. These challenges limit the development of sustainable, successful resident scholarship and are recognized as challenges for residency programs [Reference Wood, McCollum and Kukreja5]. To enhance and advance emergency medicine scholarship, Pillow, et al. proposed a framework for scholarly projects suggesting that scholarship should: (1) involve a structured process; (2) generate outcomes; (3) be disseminated; and (4) be peer reviewed [Reference Pillow, Gottlieb and Messman6].
Methods
Objective
There were two objectives. First, we sought to advance the quality of the resident scholarly activity through implementation of a sustainable immersive research program for first-year residents. Second, we sought to assess residents’ confidence in research methodology, interest in research, and perceived importance of research experience following this program.
Development process
This voluntary, year-long program was developed with the Vanderbilt University Medical Center (VUMC) Emergency Medicine Research Division, led by a senior emergency medicine resident, and mentored by content experts and faculty in the Research Division. The VUMC emergency medicine residency is a three-year program in Nashville, Tennessee, USA, that matches 13 residents annually. Representative of other emergency medicine residency programs, residents frequently complete case reports, textbook chapters, and non-peer-reviewed publications, typically toward the end of their three-year residency. Infrequently, residents completed a research project and subsequent peer-reviewed manuscript.
We developed and implemented this program for each cohort of incoming first-year residents because we rationalized that earlier exposure to research would provide residents with a better understanding of how to conduct research and allow residents to decide whether research might be a potential career path for them. Furthermore, exposing them to a group-wide project allows them to work as a cohort before clinical demands increase, which would make it difficult to meet and conduct such a shared project.
The year-long curriculum for each cohort consists of five phases and four, one-hour didactics. The five phases included: (1) preparation; (2) study design and research question; (3) data collection; (4) analysis; and (5) scientific communication. During the preparation phase that occurred prior to first-year resident arrival, a senior resident leader was identified to lead the subsequent resident research project. Each senior resident worked directly with the faculty mentors to propose, develop, and finalize the research question, draft the research protocol, and submit it for institutional review board (IRB) approval. Two faculty (MJW and JH) actively mentored the senior resident in all five phases of the study, met with the senior resident to prepare for and attend didactic sessions, provided additional supervision for data collection, conducted the analysis, and reviewed and edited manuscript drafts. However, the senior resident served as the primary interface with the first-year residents, led all training sessions, and was the first individual to answer questions and review drafts.
Didactic sessions occurred following Tuesday resident conferences to maximize availability and attendance. These four, one-hour didactic sessions corresponded with phases 2-5, study design and research question, data collection, analysis, and scientific communication. All didactics were led by the senior resident with at least one faculty mentor in attendance. Talks included an application to the existing project along with a question-and-answer session.
In the study design and research question phase, first-year residents were exposed to the PICOT (patient, intervention, comparison, outcome, time) elements of a research question and elements of study design through didactic training on the clinical topic. They were further asked to complete the necessary regulatory training. In the data collection phase, study instruments (e.g., REDCap) were developed and introduced for each project. Through the didactic session, residents were taught by the senior resident about elements of data collection, potential limitations, and strategies to mitigate weaknesses in chart review [Reference Kaji, Schriger and Green7]. Residents were further taught how to conduct chart reviews using electronic case report forms for data collection along with good data management practices by developing and maintaining data dictionaries. Data collection was piloted and randomly sampled for quality review to ensure accurate data collection. Official data collection was completed and further sampled to ensure high-quality data collection.
Following data collection, the analysis phase began, and through the didactic session, residents were taught principles of biostatistics used in the project, including descriptive and multivariable models. Data were cleaned and evaluated for missingness, outliers, and nonsensical responses (e.g., negative durations). Study results were presented in the scientific communication phase and a didactic session on preparing an abstract and manuscript was presented, and this coincided with a facilitated discussion with the resident team on the study results and implications of the findings. Sections of the manuscript were then divided into the following sections: journal requirements, abstract, introduction, methods, results, and discussion. Residents were then assigned to draft each section. A national conference abstract and peer-reviewed manuscript were planned for each class and every resident who met authorship criteria was included. During this phase, the senior resident was responsible for assembling each of the sections, editing the overall product, assembling conference and journal submissions, and working with faculty mentors.
Evaluation
To evaluate the impact of the resident research program, residents from both cohorts were asked to complete an anonymous survey before and after the year-long course. This was kept confidential so that residents could provide candid responses to the questions. The survey assessed confidence in research methodology, experience, and interest in pursuing research during and after residency using a 5-point Likert scale. The survey was distributed via REDCap questionnaires on secure email accounts [Reference Harris, Taylor, Thielke, Payne, Gonzalez and Conde11,Reference Harris, Taylor and Minor12]. Mean differences with their 95% confidence interval (95%CI) were calculated and pre- and post-means were compared using a student’s T-test.
Results
The implementation phase
The first cohort started in the 2022–2023 academic year. We found that sufficient time was necessary (approximately 3–6 months prior to the arrival of each resident class) for co-directors and the senior resident leader to refine the research question, obtain IRB approval, design the REDCap database, set first-year resident expectations, and to create didactic talks for this novel program. We conducted an open solicitation of rising senior residents for potential research questions while identifying residents interested in leading the program. We prioritized research questions that required chart review of a clinical problem to facilitate learning for new residents while gaining familiarity with the electronic health record. Following the first cohort, previous program’s lectures were updated by the senior resident to reflect the current project and any new regulatory requirements or academic content.
Following arrival, first-year residents were involved in every step of the study including finalizing the research question, piloting the data collection forms, and identifying data collection challenges. While there were four planned didactics, we found that each cohort required between one and two additional meetings for data collection training. To maximize resident availability, lectures took place in person on protected residency conference days and were recorded for review for those unable to attend. Finally, we found that the presentation of the results during the scientific communication phase served as an outline for the discussion section.
Existing departmental and research division resources were used to support the program including faculty time and regulatory support. All data management and biostatistics were completed by the mentoring faculty and have not yet required external biostatistical support. We estimated that following the initial startup of the program, this required an average of approximately 2–4 hours of faculty time per month over the course of the academic year.
Outcomes
Starting with the first cohort in July 2022, we have completed two cohorts in 2022–2023 (year 1) and the 2023–2024 (year 2) academic years, and a third cohort is in process. There was a total of 26 residents, 25 of whom completed the first year of residency and subsequently the research program. Description of the two cohorts can be seen in Table 1 and include 22 (88%) with prior research experience, and among these with a mean (standard deviation) of 3.0 (2.3) years of experience. Among both cohorts, 5 (20%) had an additional graduate degree, and 11 (44%) previously took a formal course on statistical analysis. The year 1 cohort produced a conference abstract that was accepted as a lightning oral abstract presentation at SAEM’s 2024 annual meeting [Reference Pauw, Stubblefield and Wrenn8] and a peer-reviewed publication [Reference Pauw, Stubblefield and Wrenn9]. The year 2 cohort had a poster presentation accepted at the American College of Emergency Physicians 2024 Research Forum [Reference Clark, Bruhn and Doege10] and a peer-reviewed manuscript is currently under review. Both cohorts have met the ACGME scholarly activity requirement by the completion of their first year of residency.
Participant demographics from both first-year resident cohorts
Of the 25 residents, 25 (100%) and 21 (84%) responded to the pre- and post-project survey, respectively. Survey responses using a five-point Likert scale indicated that upon completion of this novel research curriculum, there was an increase in four out of 21 elements of residents’ perceived confidence in research methodology queried (Table 2). These included confidence in recognizing the stages of clinical and translational research (pre-post difference 0.68, 95% confidence interval [CI] 0.12–1.24), identifying approaches to enhance the transparency, rigor, and reproducibility of the research project (pre-post difference 0.61, 95%CI 0.02–1.19), listing resources for study design and analysis (pre-post difference 0.57, 95%CI 0.00–1.13), and listing venues to present research (pre-post difference 0.72, 95%CI 0.07–1.38). There was no significant change in confidence in research skills, likelihood to pursue research during and after residency, and perceived importance of research experience for their residency training.

Discussion
Our curriculum demonstrated a standardized, reproducible approach to improve the scholarship program for emergency medicine residents. This curriculum succeeded in the production of peer-reviewed scholarly products that meet the ACGME scholarly activity requirement, provided residents with immersion in a research experience, and gave them tangible products to bolster their post-residency applications, all by the end of their first year of residency. Senior resident leaders gained a first author, conference abstract presentation and peer-reviewed publication, and peer leadership experience. Further, this program provided a feasible approach to meet the suggested framework for high-quality scholarship [Reference Pillow, Gottlieb and Messman6].
This novel approach to resident research allowed early research immersion in residency training to provide both project-based learning and to facilitate exposure for residents who may consider future research training. This approach may be generalizable to other residency programs, regardless of clinical specialty. The use of chart review is one potential study design that is feasible and leverages the cohort of residents who participated. By conceptualizing and refining the project prior to the arrival of the first-year residents, this preparatory work greatly facilitated participation and timely completion of the project within the year but may have had the unintended consequence of diminishing enthusiasm for the study topic. We also found that variable resident attendance due to shift times and off-service rotations that might diminish engagement could be mitigated by recording in-person meetings and lectures for later review.
The pre- and post-survey data suggest our intervention improved resident confidence in research methodology across four measures. By increasing confidence in research methodology, residents may be better prepared to critically analyze and apply principles of evidence-based medicine into their daily practice.
There are three important limitations to this approach to resident research curriculum. First, our residency has a highly engaged and robust research division which may limit generalizability to other academic programs. Programs without such research expertise within their department may consider partnering with other departments or institutions. Second, we assessed resident perceptions of confidence in research domains rather than actual competency. Further, this was a small sample size as evidenced by the wide confidence intervals. With completion of future resident cohorts, we will also assess attitudes toward research as a career and the pursuit of research fellowships. Finally, we did not track individual responses before and after the program because we conceptualized this as an anonymous survey, which may limit the identification of individuals with a greater enthusiasm for future research opportunities.
Conclusion
This novel resident research curriculum developed for an emergency medicine residency program demonstrated a standardized, reproducible, and sustainable approach to provide residents with an immersive research experience. Residents demonstrated increased confidence in their research skills. Further investigation is necessary to examine the impact on future resident research knowledge and willingness to pursue future research training.
