RESUMEN

ABSTRACT: Most medical schools have instituted undergraduate medical education (UME) well-being programs in recent years in response to high rates of medical student distress, but there is currently significant variability in the structure of UME well-being programs and limited guidance on how to best structure such programs to achieve success. In this article, the authors, all leaders of medical student well-being programs at their home institutions and members of the Association of American Medical Colleges Group on Student Affairs Committee on Student Affairs Working Group on Medical Student Well-Being between 2019 and 2023, offer guidance to the national community on how best to structure a UME well-being program. They use the current literature and their professional experiences leading well-being efforts at 7 different institutions to review the case for addressing medical student well-being, propose a guiding model, and make recommendations for strategies to implement this model.The proposed guiding model emphasizes the importance of the learning environment and efficiency of learning to medical student well-being, as well as personal resilience. Based on this model, the authors recommend specific and tangible well-being strategies to implement systemic interventions to improve the learning environment, efficiency of learning, and personal resilience, including: formalizing the well-being program; hiring qualified, dedicated, and empowered well-being leadership with clear responsibilities; acting as a central hub for resources and as a liaison with mental health care; and establishing robust program evaluation methods.

RESUMEN

PURPOSE: To evaluate the association of baseline morphologic stage of rhegmatogenous retinal detachment (RRD) using OCT with postoperative anatomic and visual acuity (VA) outcomes. DESIGN: Retrospective cohort study. SUBJECTS: Consecutive primary fovea-involving RRDs referred from January 2012 to September 2022. METHODS: Patients with primary RRD and no prior macular pathology with gradable baseline OCT were assessed. Best-corrected VA (BCVA) was assessed at presentation and at 3, 6, and 12 months postoperatively. OCT scans were graded for parafoveal morphologic stage of RRD and foveal photoreceptor integrity. MAIN OUTCOME MEASURES: Association of morphologic stage of RRD with 12-month BCVA. RESULTS: Three hundred fifty-one patients were included. Sixty-eight percent (238/351) were male, the mean (standard deviation) age was 61.2 (± 12.8) years, and 59% (206/351) were phakic. Thirteen percent (47/351) presented in stages 1 and 2, 15% (54/351) in stage 3a, 36% (126/351) in stage 3b, 24% (83/351) in stage 4, and 12% (41/351) in stage 5. Increasing stage was associated with worse foveal photoreceptor integrity, reduced baseline BCVA and longer duration of central vision loss (P < 0.001). Mean (standard deviation) 12-month BCVA by stage was 0.77 (± 0.64) for stages 1 and 2, 1.00 (± 0.53) for stage 3a, 1.36 (± 0.55) for stage 3b, 1.33 (± 0.66) for stage 4 and 1.55 (± 0.47) for stage 5. Increasing stage was associated with reduced postoperative BCVA (P < 0.001) at all time points after adjusting for covariates. A subgroup analysis of acute detachments with retinal pigment epithelium-photoreceptor dysregulation demonstrated no difference in postoperative BCVA between stages 1, 2, and 3a. However, 12-month BCVA was significantly better in stages 1, 2, and 3a vs. stage 3b (P = 0.002) and stage 3a vs. 3b (P = 0.008). CONCLUSIONS: This study validates the clinical relevance of a recently proposed OCT-based staging system for outer retinal morphologic changes over time in RRD. Postoperative BCVA was significantly reduced in patients with worse presenting stage at all time points. In acute RRDs, 12-month BCVA was significantly better in stages 1, 2, and 3a vs. stage 3b, which suggests early stages may have better retinal recovery compared with stage 3b or worse. Stage 3b may represent a critical point where substantial structural changes occur, leading to worse outcomes in acute RRDs. Patients presenting with fovea-involving RRDs in stages 1, 2, or 3a may benefit from more urgent intervention.

RESUMEN

BACKGROUND: While student-run free clinics (SRFCs) play an important role in care for underserved populations, few mechanisms exist to promote collaboration among regional SRFCs. AIMS: To address this gap, the Chicagoland Free Clinics Consortium (CFCC) was formed to (1) facilitate collaboration between Chicagoland SRFCs, (2) provide innovation grant funding, and (3) host an annual conference. SETTING AND PARTICIPANTS: In 2018, students from the Pritzker School of Medicine founded the CFCC and partnered with peers from area schools to implement programming. PROGRAM DESCRIPTION: Between 2018 and 2022, CFCC engaged 23 SRFCs representing all 6 Chicagoland schools, held 4 annual conferences, and distributed $15,423 in grants to 19 projects at 14 SRFC sites. PROGRAM EVALUATION: A total of 176 students from 5 schools attended the 4 conferences. In 2022, 82 unique participants were surveyed, and 66% (54/82) responded. Eighty percent (43/54) reported they were "more likely to collaborate with other Chicagoland free clinics." In 2022, all grant sites were surveyed and 84% (16/19) responded. Most (87%,14/16) agreed the grant "allowed them to implement a project that would not have otherwise been accomplished" and 21% (4/19) were inter-institutional collaborations. DISCUSSION: To our knowledge, CFCC is the first student-led organization to promote sustained collaboration across SRFCs in a metropolitan area.

RESUMEN

Purpose: To describe the pathophysiology of secondary macular hole (MH) in rhegmatogenous retinal detachment (RRD). Methods: A retrospective cohort of 360 consecutive primary fovea-off RRDs presenting to St. Michael's Hospital, Toronto, from January 2012 to September 2022 were included. Preoperative OCT was assessed for bacillary layer detachment (BALAD) abnormalities. Histological sections of normal eyes were assessed to inform OCT interpretations. Primary outcome measure was the progression of BALAD to full-thickness MH (FTMH). Results: Of the 360 patients, 22.5% (n = 81) had BALAD abnormalities at presentation. Eight percent (29/360) had associated MH, of which 79.3% (23/29) were a BALAD-lamellar hole and 20.7% (6/29) were FTMH. After reattachment, 62% of MHs persisted (18/29), of which 83% (15/18) had BALAD-lamellar holes that subsequently progressed to FTMH in a mean of 8.1 ± 3.2 days. BALAD-lamellar holes had significantly worse postoperative visual acuity (P < 0.001) when compared with other BALAD abnormalities (58/81) or with the rest of the cohort (279/360). OCT spectrum from BALAD to FTMH includes (1) cleavage planes extending from Henle fiber layer into the BALAD; (2) central outer nuclear layer thinning; (3) Müller cell cone loss with tissue remnants at the foveal walls; (4) retinal tissue operculum close to BALAD-MH; and (5) progressive thinning or degradation of the posterior band of BALAD-lamellar hole leading to FTMH. Histological specimens identified foveal regions of low mechanical stability. Conclusions: BALAD plays a crucial role in the pathophysiology of MH in RRDs, which forms owing to sequential changes in four critical areas: RPE-photoreceptor interface, myoid zone, Henle fiber layer, and Müller cell cone with surrounding tissue. Timely management of fovea-off RRD with BALAD may be prudent to avoid the progression to BALAD-lamellar hole, subsequent FTMH, and worse functional outcomes.

RESUMEN

The Liaison Committee on Medical Education (LCME) requires that well-being programs must be "effective." Yet most medical schools do not robustly assess their well-being programs. Most evaluate their programs using one question on the Association of American Medical College's annual Graduation Questionnaire (AAMC GQ) survey for fourth-year students on their satisfaction with well-being programs, which is inadequate and nonspecific and only assesses a specific time in training. In this perspective, we, as members of the AAMC Group on Student Affairs (GSA) - Committee on Student Affairs (COSA) Working Group on Medical Student Well-being, suggest adapting Kern's 6-step approach to curriculum development as an effective framework to guide the development and evaluation of well-being programs. We suggest strategies for applying Kern's steps to well-being programs, with attention to conducting needs assessments, identifying goals, implementation, and evaluation and feedback. While each institution will have unique goals emerging from their needs assessment, we put forth five common medical student well-being goals as examples. Applying a rigorous and structured approach to developing and evaluating undergraduate medical education well-being programs will involve defining a guiding philosophy and clear goals and implementing a strong assessment strategy. This Kern-based framework can help schools meaningfully assess the impact of their initiatives on student well-being.

RESUMEN

Telehealth services, specifically telemedicine audio-video and audio-only patient encounters, expanded dramatically during the COVID-19 pandemic through temporary waivers and flexibilities tied to the public health emergency. Early studies demonstrate significant potential to advance the quintuple aim (patient experience, health outcomes, cost, clinician well-being, and equity). Supported well, telemedicine can particularly improve patient satisfaction, health outcomes, and equity. Implemented poorly, telemedicine can facilitate unsafe care, worsen disparities, and waste resources. Without further action from lawmakers and agencies, payment will end for many telemedicine services currently used by millions of Americans at the end of 2024. Policymakers, health systems, clinicians, and educators must decide how to support, implement, and sustain telemedicine, and long-term studies and clinical practice guidelines are emerging to provide direction. In this position statement, we use clinical vignettes to review relevant literature and highlight where key actions are needed. These include areas where telemedicine must be expanded (e.g., to support chronic disease management) and where guidelines are needed (e.g., to prevent inequitable offering of telemedicine services and prevent unsafe or low-value care). We provide policy, clinical practice, and education recommendations for telemedicine on behalf of the Society of General Internal Medicine. Policy recommendations include ending geographic and site restrictions, expanding the definition of telemedicine to include audio-only services, establishing appropriate telemedicine service codes, and expanding broadband access to all Americans. Clinical practice recommendations include ensuring appropriate telemedicine use (for limited acute care situations or in conjunction with in-person services to extend longitudinal care relationships), that the choice of modality be done through patient-clinician shared decision-making, and that health systems design telemedicine services through community partnerships to ensure equitable implementation. Education recommendations include developing telemedicine-specific educational strategies for trainees that align with accreditation body competencies and providing educators with protected time and faculty development resources.

RESUMEN

PURPOSE: To determine if fluid-fluid exchange (endo-drainage) or external needle drainage can result in retinal displacement following minimal gas vitrectomy (MGV) with no fluid-air exchange for rhegmatogenous retinal detachment (RRD) repair. METHODS: Two patients with macula off RRD underwent MGV with and without segmental buckle. First case had minimal gas vitrectomy with segmental buckle (MGV-SB), along with endo-drainage, while the second case had MGV only with external fluid drainage. At the completion of surgery, the patient was immediately log rolled to face down for 6 hours followed by positioning to the break. RESULTS: Both patients achieved retinal reattachment and post-operative wide-field fundus autofluorescence imaging demonstrated a low integrity retinal attachment (LIRA) with retinal displacement. CONCLUSIONS: Iatrogenic fluid drainage techniques such as fluid-fluid exchange or external needle drainage during MGV (without fluid-air exchange) may result in retinal displacement. Allowing the retinal pigment epithelial pump to reabsorb the fluid naturally may reduce the risk of retinal displacement.

RESUMEN

This article presents high-resolution swept-source optical coherence tomography (SS-OCT) imaging data used to elaborate a mechanical model that elucidates the formation of outer retinal corrugations (ORCs) in rhegmatogenous retinal detachments (RRD). The imaging data shared in the repository and presented in this article is related to the research paper entitled "Outer Retinal Corrugations in Rhegmatogenous Retinal Detachment: The Retinal Pigment Epithelium-Photoreceptor Dysregulation Theory" (Muni et al., AJO, 2022). The dataset consists of 69 baseline cross-sectional SS-OCT scans from 66 patients that were assessed for the presence of ORCs and analyzed considering the clinical features of each case. From the 66 cases, we selected SS-OCT images of 4 RRD patients with visible ORCs and no cystoid macular edema (CME) to validate the mechanical model. We modelled the retina as a composite material consisting of the outer retinal layer (photoreceptor layer) and the inner retinal layer (the part of the retina that excludes the photoreceptor layer) with thicknesses T o and T i and elastic modulus E o and E i , respectively. The thickness of the outer and inner retinal layers and the relative increase in the length of the outer retinal layer (γ) were measured from the SS-OCT images. Measurements from the SS-OCT images of patients with RRD demonstrated a 30% increase (γ=0.3) in the length of the outer retinal layer and a 400% increase in the thickness of the outer retinal layer (To). Using the mathematical model, Eo/Ei ranged between 0.05 to 0.5 to result in ORCs with a similar frequency to those observed in the SS-OCT scans.

RESUMEN

Adhering to the paradigm of the natural sciences, much of undergraduate medical education (UME) in the United States remains committed to objectivity, compliance, and standardization in its approach to teaching, evaluation, student affairs, and accreditation practices. The authors argue that, while these simple and complicated problem solving (SCPS) approaches may be valid for some highly controlled environments of UME, they lack rigor in complex, real-world environments where optimal care and education is not standardized but is tailored to context and individual needs. This argument is supported by evidence that "systems" approaches, characterized by complex problem solving (CPS, differentiated from complicated problem solving), lead to better outcomes in patient care and student academic performance. Examples of interventions implemented at the University of Chicago Pritzker School of Medicine from 2011 to 2021 further illustrate this point. Interventions in student well-being that emphasize personal and professional growth have led to student satisfaction that is 20% higher than the national average on the Association of American Medical Colleges Graduation Questionnaire (GQ). Career advising interventions that augment the use of adaptive behaviors in place of rules and guidelines have yielded 30% fewer residency applications per student than the national average while simultaneously yielding residency "unmatched" rates that are one-third of the national average. Regarding diversity, equity, and inclusion, an emphasis on civil discourse around real-world problems has been associated with student attitudes toward diversity that are 40% more favorable than the national average on the GQ. In addition, there has been an increase in the number of matriculating students who are underrepresented in medicine to 35% of the incoming class. The article concludes with a review of philosophic barriers to incorporating the CPS paradigm into UME and of notable pedagogic differences between CPS and SCPS approaches.

RESUMEN

PURPOSE: To evaluate the role of en face OCT as a diagnostic tool for the detection of persistent subretinal fluid (PSRF) and outer retinal folds (ORFs) after successful rhegmatogenous retinal detachment (RRD) repair. DESIGN: Observational post hoc analysis of 2 prospective surgical trials. PARTICIPANTS: All patients with gradable (signal strength ≥ 5 and no segmentation error) 6 × 6-mm2 macular cube scans obtained using spectral-domain OCT (Carl Zeiss Meditec) between 1 and 2 months after surgery were included in this study. METHODS: The scans were assessed for the presence or absence of PSRF or ORFs using en face OCT and cross-sectional B scans by 2 masked graders, with any disagreements adjudicated by a third senior masked grader. MAIN OUTCOME MEASURES: The sensitivity, specificity, and predictive accuracy (using area under the curve [AUC]) of en face OCT were compared with those of cross-sectional OCT, which is considered the gold standard. RESULTS: Two hundred twenty-three patients were included in this study. The Cohen kappa between the graders in the diagnosis of PSRF and ORFs using en face OCT was 0.84 and 0.86, respectively. The sensitivity of en face OCT was 100% (95% confidence interval [CI], 100%-100%) in the diagnosis of PSRF and 98.8% (95% CI, 96.5%-101.1%) in the diagnosis of ORFs. Similarly, the specificity of en face OCT was 98.7% (95% CI, 96.8%-100.5%) and 84.2% (95% CI, 78.1%-90.2%) in the diagnosis of PSRF and ORFs, respectively. The AUC was 0.99 for PSRF and 0.91 for ORFs. CONCLUSIONS: En face OCT has good sensitivity, specificity, and predictive accuracy (using AUC) in the diagnosis of PSRF and ORFs. En face OCT is an efficient screening tool for postoperative anatomic abnormalities, such as PSRF and ORFs, after RRD repair.

RESUMEN

PURPOSE: To demonstrate how a small gas bubble injected into the vitreous cavity in pneumatic retinopexy for rhegmatogenous retinal detachment causes immediate displacement of subretinal fluid and to gain insights into the potential mechanism of retinal displacement. METHODS: Three patients with rhegmatogenous retinal detachment who underwent pneumatic retinopexy were enrolled and prospectively followed. All patients underwent ultra-widefield fundus photography at baseline and at 1 to 2 minutes after intravitreal gas injection. RESULTS: In all cases, the ultra-widefield fundus photograph demonstrated immediate displacement of subretinal fluid, suggesting that the buoyant force applied to the retina by the bubble was responsible for the displacement of subretinal fluid. The results were extrapolated to determine the buoyant force applied by a small and large gas bubble as in pneumatic retinopexy and pars plana vitrectomy. We determined that the buoyant force applied with a larger bubble in pars plana vitrectomy was substantially greater, and this may lead to retinal displacement. CONCLUSION: Intravitreal gas applies significant buoyant force to the detached retina and subretinal fluid that leads to substantial and rapid displacement of subretinal fluid. Understanding the affect of the buoyant force of the gas bubble on the detached retina can provide insight into possible mechanisms of retinal displacement.

RESUMEN

BACKGROUND/AIM: To assess the utility of single-capture ultra-widefield confocal scanning laser ophthalmoscope with integrated swept-source optical coherence tomography (UWF-SS-OCT) in the management of rhegmatogenous retinal detachment (RRD) and associated peripheral pathology. METHODS: 138 eyes of 101 consecutive patients with RRD and/or associated peripheral pathology at a vitreoretinal practice in Toronto, Canada between December 2020 and February 2021 that had UWF-SS-OCT with interpretable scans were included. A 200 degree fundus photograph was used to navigate a built-in 100 kHz UWF-SS-OCT to image pathology with a high-density 23 mm line scan and/or volume scan. Main outcomes were the microstructural details of the RRD and/or associated peripheral pathology and longitudinal assessment of response to laser retinopexy and cryopexy with UWF-SS-OCT. RESULTS: 56.5% (78/138) of eyes had prior or current RRD (6 eyes had combined retinoschisis detachment), 31.1% (43/138) had retinal tears/holes and 14.5% (20/138) had lattice degeneration. UWF-SS-OCT impacted management and was useful in determining the presence or absence of vitreoretinal traction with retinal holes or tears. It was also helpful in differentiating retinal detachment, schisis-detachment and retinoschisis in cases where it was not apparent clinically. There were also several novel findings such as vitreous adhesion at the posterior border of a retinal dialysis. UWF-SS-OCT was performed longitudinally before and immediately following laser retinopexy (n=22) and cryopexy (n=4). Microstructural changes were consistent with chorioretinal adhesion immediately following laser versus postprocedure day 6 following cryopexy. CONCLUSION: Single-capture UWF-SS-OCT enabled novel insights in RRD and associated peripheral vitreoretinal pathology.

RESUMEN

PURPOSE: To present a novel technique, minimal gas vitrectomy with scleral buckle, as a means of potentially minimizing retinal displacement compared with standard vitrectomy or vitrectomy/scleral buckle for select cases. METHODS: A patient with right macula-off retinal detachment and retinal breaks at 7 o'clock and 10 o'clock underwent a 23-gauge pars plana vitrectomy, localization, and cryopexy of the breaks along with an inferior temporal segmental scleral buckle. No air-fluid exchange was performed. Suturing of sclerotomies, anterior chamber paracentesis of 0.3 mL, and intravitreal injection of 0.6 mL pure sulfur hexafluoride were then performed. The patient was advised to perform the steamroller maneuver with initial face-down positioning for 6 hours. RESULTS: The patient achieved retinal reattachment, and postoperative wide-field fundus autofluorescence imaging demonstrated high-integrity retinal attachment with no retinal displacement. CONCLUSION: The minimal gas vitrectomy with scleral buckle technique has the potential to minimize retinal displacement in cases with inferior break(s) by using a small volume expansile gas tamponade and localized scleral buckle compared with standard vitrectomy or vitrectomy/scleral buckle with a full gas fill.

RESUMEN

PURPOSE: To describe bacillary layer detachment and related abnormalities of the foveal bouquet in rhegmatogenous retinal detachment and assess their impact on photoreceptor recovery and full-thickness macular hole formation, using optical coherence tomography. METHODS: Prospective cohort of 93 consecutive patients with fovea-off rhegmatogenous retinal detachment presenting to St. Michael's Hospital from January 2020 to April 2022, with gradable preoperative foveal optical coherence tomography. RESULTS: 23.7% (22/93) of patients had evidence of bacillary layer detachment and associated abnormalities. The mean fovea-off duration was 6.4 days (±5.6 SD). 86.4% (19/22) had foveal bacillary layer detachment, 15.8% (3/19) of which had cleavage planes extending from the outer nuclear layer into the myoid zone, and 14% (3/22) had an inner lamellar hole with a residual bridge of photoreceptor remnants (all of which progressed to full-thickness macular hole). Among patients with gradable optical coherence tomography at 3 months post-operatively, 80% (12/15) had ellipsoid zone discontinuity, which persisted in 41% (5/12) at 1 year. CONCLUSION: Bacillary layer detachment was described for the first time in the setting of rhegmatogenous retinal detachment. This is hypothesized to occur from horizontal traction secondary to hydration/lateral expansion of the outer retina in the presence of the Müller cell cone scaffold. Bacillary layer detachment may render the fovea susceptible to further injury, possibly representing a pathophysiological basis for full-thickness macular hole formation in rhegmatogenous retinal detachment.

RESUMEN

PURPOSE: To describe the sequential morphologic changes after rhegmatogenous retinal detachment (RRD) utilizing a novel, objective, and clinically relevant staging system based on swept-source OCT (SS-OCT) and determine its association with the duration of fovea-off and postoperative visual acuity (VA). DESIGN: Prospective cohort study. SUBJECTS: Consecutive patients with primary fovea-involving RRD referred to St. Michael's Hospital, Toronto, Canada, from January 2020 to April 2022. METHODS: All patients underwent SS-OCT and ultrawide-field SS-OCT at baseline. Primary RRDs with breaks above the 8- and 4-o'clock meridians were included. Patients with vision loss for ≥ 3 months, proliferative vitreoretinopathy grade C or worse, a demarcation line, previous vitrectomy, or other retinal pathology were excluded. The staging was based on an assessment of outer retinal morphology on successive SS-OCT scans from the peripheral break to the most posterior aspect of the RRD, following its direction of progression. MAIN OUTCOME MEASURES: Sequential outer retinal morphologic changes observed using SS-OCT and associated VA at 3 months after surgery. RESULTS: Forty-nine eyes were included. The mean age (standard deviation [SD]) was 61.2 (15.2) years. The mean presenting logarithm of the minimum angle of resolution (SD) acuity was 1.09 (0.75). All stages observed on a high-definition horizontal 51-line scan were reported. Outer retinal changes occurred in 5 stages: (1) separation of the neurosensory retina from the retinal pigment epithelium (42/49, 85.7%); (2) thickening of inner and outer segments of photoreceptors (45/49, 91.8%); (3) outer retinal corrugation formation: (3a) low-frequency (44/49, 93.6%) and (3b) high-frequency outer retinal corrugations (42/49, 85.7%); (4) loss of the definition of outer retinal corrugations, with concurrent thickening of inner and outer segments (26/49, 53.1%); and (5) patchy (moth-eaten) or complete loss of inner and outer segments (17/49, 34.7%). The mean duration of fovea-off by stage in the parafovea (SD) was 2 (1.4), 2.3 (1.2), 11.4 (8.1), and 12 (13.3) days for stages 3a, 3b, 4, and 5, respectively. There was a statistically significant association between increasing stage of RRD and longer duration of foveal involvement (P = 0.001) and, most importantly, between increasing stage and worse VA at 3 months after surgery (P = 0.011). CONCLUSIONS: This novel staging system describes the sequential morphologic changes in RRD using SS-OCT. Increasing stage of RRD was associated with worse VA at 3 months after surgery.

RESUMEN

PROBLEM: Mental health conditions are common among medical students. While stigma contributes to low rates of help seeking, little programming exists to address stigma. APPROACH: In 2015, the authors developed a mental health initiative (MHI) to combat stigma at the Pritzker School of Medicine featuring 3 elements: (1) Mental Health Panel, an annual first-year event where faculty/peers share mental health stories; (2) Pritzker, I Screwed Up, an annual all-school event where faculty/peers share experiences with failure; and (3) Humans of Pritzker, a social media initiative featuring students' mental health posts. Postevent surveys and the 2021-2022 MHI survey assessed student satisfaction and impact on stigma and help-seeking behaviors. Student Counseling Services utilization rates for medical and nonmedical students were compared for academic years 2014-2015 vs 2018-2019 and 2020-2021 to account for the pandemic's impact on mental health care utilization. OUTCOMES: The MHI survey response rate was 61% (261/430). Respondents were distributed across class-years. Most were female (57%, 150/261). The majority agreed they could speak about mental health without judgment from peers (78%, 203/259) and faculty (57%, 149/260). Most (62%, 161/260) utilized mental health services during medical school. Of these, 41% (66/161) agreed that MHI programming contributed to their decision to seek care. On the 2021-2022 Mental Health Panel and Pritzker, I Screwed Up evaluations, almost all agreed that faculty/peers sharing experiences destigmatized mental illness (99%, 78/79) and making mistakes (96%, 152/159). Student Counseling Services utilization increased from 8% (32/389) for 2014-2015 to 19% (75/394) for 2018-2019 and 33% (136/406) for 2020-2021 for medical students, compared with 19% (2,248/12,138) to 21% (3,024/14,293) and 22% (3,285/15,004) for nonmedical students. NEXT STEPS: Faculty and peers sharing mental health stories may help reduce stigma and increase help seeking in medical students. Future work should explore the longitudinal impact of programming and disseminating similar initiatives at other institutions.
