Identifying Contact Time Required for Secondary Transmission of Clostridioides difficile Infections by Using Real-Time Locating System.

Considering patient room shortages and prevalence of other communicable diseases, reassessing the isolation of patients with Clostridioides difficile infection (CDI) is imperative. We conducted a retrospective study to investigate the secondary CDI transmission rate in a hospital in South Korea, where patients with CDI were not isolated. Using data from a real-time locating system and electronic medical records, we investigated patients who had both direct and indirect contact with CDI index patients. The primary outcome was secondary CDI transmission, identified by whole-genome sequencing. Among 909 direct and 2,711 indirect contact cases, 2 instances of secondary transmission were observed (2 [0.05%] of 3,620 cases), 1 transmission via direct contact and 1 via environmental sources. A low level of direct contact (113 minutes) was required for secondary CDI transmission. Our findings support the adoption of exhaustive standard preventive measures, including environmental decontamination, rather than contact isolation of CDI patients in nonoutbreak settings.

The Association of ACGME Milestones With Performance on American Board of Surgery Assessments: A National Investigation of Surgical Trainees.

OBJECTIVE: To determine the relationship between, and predictive utility of, milestone ratings and subsequent American Board of Surgery (ABS) vascular surgery in-training examination (VSITE), vascular qualifying examination (VQE), and vascular certifying examination (VCE) performance in a national cohort of vascular surgery trainees. BACKGROUND: Specialty board certification is an important indicator of physician competence. However, predicting future board certification examination performance during training continues to be challenging. METHODS: This is a national longitudinal cohort study examining relational and predictive associations between Accreditation Council for Graduate Medical Education (ACGME) Milestone ratings and performance on VSITE, VQE, and VCE for all vascular surgery trainees from 2015 to 2021. Predictive associations between milestone ratings and VSITE were conducted using cross-classified random-effects regression. Cross-classified random-effects logistic regression was used to identify predictive associations between milestone ratings and VQE and VCE. RESULTS: Milestone ratings were obtained for all residents and fellows(n=1,118) from 164 programs during the study period (from July 2015 to June 2021), including 145,959 total trainee assessments. Medical knowledge (MK) and patient care (PC) milestone ratings were strongly predictive of VSITE performance across all postgraduate years (PGYs) of training, with MK ratings demonstrating a slightly stronger predictive association overall (MK coefficient 17.26 to 35.76, ß = 0.15 to 0.23). All core competency ratings were predictive of VSITE performance in PGYs 4 and 5. PGY 5 MK was highly predictive of VQE performance [OR 4.73, (95% CI, 3.87-5.78), P <0.001]. PC subcompetencies were also highly predictive of VQE performance in the final year of training [OR 4.14, (95% CI, 3.17-5.41), P <0.001]. All other competencies were also significantly predictive of first-attempt VQE pass with ORs of 1.53 and higher. PGY 4 ICS ratings [OR 4.0, (95% CI, 3.06-5.21), P <0.001] emerged as the strongest predictor of VCE first-attempt pass. Again, all subcompetency ratings remained significant predictors of first-attempt pass on CE with ORs of 1.48 and higher. CONCLUSIONS: ACGME Milestone ratings are highly predictive of future VSITE performance, and first-attempt pass achievement on VQE and VCE in a national cohort of surgical trainees.

Gender Differences in Work-Based Assessment Scores and Narrative Comments After Direct Observation.

BACKGROUND: While some prior studies of work-based assessment (WBA) numeric ratings have not shown gender differences, they have been unable to account for the true performance of the resident or explore narrative differences by gender. OBJECTIVE: To explore gender differences in WBA ratings as well as narrative comments (when scripted performance was known). DESIGN: Secondary analysis of WBAs obtained from a randomized controlled trial of a longitudinal rater training intervention in 2018-2019. Participating faculty (n = 77) observed standardized resident-patient encounters and subsequently completed rater assessment forms (RAFs). SUBJECTS: Participating faculty in longitudinal rater training. MAIN MEASURES: Gender differences in mean entrustment ratings (4-point scale) were assessed with multivariable regression (adjusted for scripted performance, rater and resident demographics, and the interaction between study arm and time period [pre- versus post-intervention]). Using pre-specified natural language processing categories (masculine, feminine, agentic, and communal words), multivariable linear regression was used to determine associations of word use in the narrative comments with resident gender, race, and skill level, faculty demographics, and interaction between the study arm and the time period (pre- versus post-intervention). KEY RESULTS: Across 1527 RAFs, there were significant differences in entrustment ratings between women and men standardized residents (2.29 versus 2.54, respectively, p < 0.001) after correction for resident skill level. As compared to men, feminine terms were more common for comments of what the resident did poorly among women residents (ß 0.45, CI 0.12-0.78, p 0.01). This persisted despite adjusting for the faculty's entrustment ratings. There were no other significant linguistic differences by gender. CONCLUSIONS: Contrasting prior studies, we found entrustment rating differences in a simulated WBA which persisted after adjusting for the resident's scripted performance. There were also linguistic differences by gender after adjusting for entrustment ratings, with feminine terms being used more frequently in comments about women in some, but not all narrative comments.

The rapid growth and expansion of Master of health professions education (MHPE) programs: A mixed-methods study of international curricular trends and guidelines for programs.

PURPOSE: This study explores international trends and standards of Master's degree programs through a comprehensive environmental scan and focus group interviews to understand curricular structure, content, program director expectations, educational context, and future directions. METHOD: Authors conducted a two-phase mixed-methods sequential explanatory design to conduct the environmental scan (phase 1), and subsequently conducting focus groups (phase 2) with program directors. A population list of Master's programs was used to generate a sampling frame, considering the geographic region (continent) and institution type (university, organization, public institution). Qualitative data were coded to analyze the breadth and depth of courses. Three one-hour virtual focus group interviews were conducted with ten program directors. RESULTS: The population list of 159 Masters programs worldwide was used to create a sample for analysis in the environmental scan (n = 46 Masters programs), representing programs from North America, Europe, Australia, and South Africa. Most programs (39%) delivered their courses online, with 20% exclusively offering an in-person program. Focus group participants indicated expectations of graduates, context in which they learn, as well as future directions for improving health professions education graduate programs. CONCLUSION: Program directors should consider programmatic aims, localized needs, and quality/standard of the program in designing Masters programs, with individualized growth opportunities for learners.

The Inconspicuous Learner Handover: An Exploratory Study of U.S. Emergency Medicine Program Directors' Perceptions of Learner Handovers from Medical School to Residency.

Phenomenon: Central to competency-based medical education is the need for a seamless developmental continuum of training and practice. Trainees currently experience significant discontinuity in the transition from undergraduate (UME) to graduate medical education (GME). The learner handover is intended to smooth this transition, but little is known about how well this is working from the GME perspective. In an attempt to gather preliminary evidence, this study explores U.S. program directors (PDs) perspective of the learner handover from UME to GME. Approach: Using exploratory qualitative methodology, we conducted semi-structured interviews with 12 Emergency Medicine PDs within the U.S. from October to November, 2020. We asked participants to describe their current perception of the learner handover from UME to GME. Then we performed thematic analysis using an inductive approach. Findings: We identified two main themes: The inconspicuous learner handover and barrier to creating a successful UME to GME learner handover. PDs described the current state of the learner handover as "nonexistent," yet acknowledged that information is transmitted from UME to GME. Participants also highlighted key challenges preventing a successful learner handover from UME to GME. These included: conflicting expectations, issues of trust and transparency, and a dearth of assessment data to actually hand over. Insights: PDs highlight the inconspicuous nature of learner handovers, suggesting that assessment information is not shared in the way it should be in the transition from UME to GME. Challenges with the learner handover demonstrate a lack of trust, transparency, and explicit communication between UME and GME. Our findings can inform how national organizations establish a unified approach to transmitting growth-oriented assessment data and formalize transparent learner handovers from UME to GME.

Teaching foundational language equity concepts in the pre-clinical curriculum.

BACKGROUND: Despite the prevalence of non-English languages in the US population, existing medical training to teach communication with linguistically diverse communities is limited to electives or solely focuses on medical interpreting. Language-appropriate communication skills are seldom comprehensively integrated in medical education. This study describes the development and evaluation of an intervention to teach foundational language equity concepts. METHODS: The authors implemented a pre-clinical language equity course at three medical school campuses between August 2020 and March 2022. Sessions focused on the impact of language in health, physician language proficiency standards, and working with medical interpreters. The study sought to (1) understand students' language skills and prior clinical experiences with patients with non-English language preference and (2) evaluate the curriculum's impact. Students self-reported their language skills and experiences as part of a voluntary pre-questionnaire. Pre and post-questionnaires evaluated knowledge, attitudes, and intent to apply language equity concepts. Descriptive statistics and chi-squared tests were used to examine trends; themes were identified from free-text responses. RESULTS: Overall, 301 students completed the course, 252 (83%) completed at least one questionnaire; for each session, between 35% and 46% of learners completed both pre and post-questionnaires. Three quarters (189/252) reported non-English languages. Over half (138/252) reported previous non-English language patient care, and 28% (62/224) had served as ad hoc (untrained) interpreters. Only two students (< 1%) had ever been assessed for medical language abilities. Students demonstrated improved post-course language equity knowledge, strategies for interpreter-mediated encounters, and likelihood to report a plan for language skills assessment (all p < .001). Most plans were multifaceted (61%, 38/62), involving goals like completing a language course, taking a proficiency exam, openly discussing skills and uncertainties with team members, and increasing professional interpreter utilization. CONCLUSIONS: A longitudinal language equity curriculum can be feasibly integrated in pre-clinical education, highlight the linguistic diversity of the student body, and serve as a first step in ensuring that all students have a strong language equity foundation prior to clinical rotations. Future steps include evaluating the intervention's potential long-term effects on professional interpreter utilization, student clinical performance, and institutional culture that promotes multilingualism.

Analysis of narrative assessments of internal medicine resident performance: are there differences associated with gender or race and ethnicity?

BACKGROUND: Equitable assessment is critical in competency-based medical education. This study explores differences in key characteristics of qualitative assessments (i.e., narrative comments or assessment feedback) of internal medicine postgraduate resident performance associated with gender and race and ethnicity. METHODS: Analysis of narrative comments included in faculty assessments of resident performance from six internal medicine residency programs was conducted. Content analysis was used to assess two key characteristics of comments- valence (overall positive or negative orientation) and specificity (detailed nature and actionability of comment) - via a blinded, multi-analyst approach. Differences in comment valence and specificity with gender and race and ethnicity were assessed using multilevel regression, controlling for multiple covariates including quantitative competency ratings. RESULTS: Data included 3,383 evaluations with narrative comments by 597 faculty of 698 residents, including 45% of comments about women residents and 13.2% about residents who identified with race and ethnicities underrepresented in medicine. Most comments were moderately specific and positive. Comments about women residents were more positive (estimate 0.06, p 0.045) but less specific (estimate - 0.07, p 0.002) compared to men. Women residents were more likely to receive non-specific, weakly specific or no comments (adjusted OR 1.29, p 0.012) and less likely to receive highly specific comments (adjusted OR 0.71, p 0.003) or comments with specific examples of things done well or areas for growth (adjusted OR 0.74, p 0.003) than men. Gendered differences in comment specificity and valence were most notable early in training. Comment specificity and valence did not differ with resident race and ethnicity (specificity: estimate 0.03, p 0.32; valence: estimate - 0.05, p 0.26) or faculty gender (specificity: estimate 0.06, p 0.15; valence: estimate 0.02 p 0.54). CONCLUSION: There were significant differences in the specificity and valence of qualitative assessments associated with resident gender with women receiving more praising but less specific and actionable comments. This suggests a lost opportunity for well-rounded assessment feedback to the disadvantage of women.

Measuring Emergency Department Workload Perception Using Electronic Medical Record Measures of Patient Volume and Acuity.

BACKGROUND: Workload in the emergency department (ED) fluctuates and there is no established model for measurement of clinician-level ED workload. OBJECTIVE: The aim of this study was to measure perceived ED workload and assess the relationship between perceived workload and objective measures of workload from the electronic medical record (EMR). METHODS: This study was conducted at a tertiary care, academic ED from July 1, 2020 through April 13, 2021. Attending workload perceptions were collected using a 5-point scale in three care areas with variable acuity. We collected eight EMR measures thought to correlate with perceived workload. EMR values were compared across areas of the department using ANOVA and correlated with attending workload ratings using linear regression. RESULTS: We collected 315 unique workload ratings, which were normally distributed. For the entire department, there was a weak positive correlation between reported workload perception and mean percentage of inpatient admissions (r = 0.23; p < 0.001), intensive care unit admissions (r = 0.2; p < 0.001), patient arrivals per shift (r = 0.14; p = 0.017), critical care billed visits (r = 0.22; p < 0.001), cardiopulmonary resuscitation code activations (r = 0.2; p < 0.001), and level 5 visits (r = 0.13; p = 0.02). There was weak negative correlation for ED discharges (r = -0.23; p < 0.001). Several correlations were stronger in individual care areas, including percent admissions in the lowest-acuity area (r = 0.43; p = 0.033) and patient arrivals in the highest-acuity area (r = 0.44; p < .01). No significant correlation was found in any area for observation admissions or trauma activations. CONCLUSIONS: In this study, EMR measures of workload were not closely correlated with ED attending physician workload perception. Future study should examine additional factors contributing to physician workload outside of the EMR.

The Impact of Simulation Based Training on the Fundamentals of Endoscopic Surgery Performance Examination.

OBJECTIVE: To determine if simulation training is required to pass the FES skills test and assess the relationship between simulation training, clinical training, and FES skills test performance. SUMMARY OF BACKGROUND DATA: The ABS began requiring completion of the Flexible Endoscopy Curriculum for all applicants beginning in 2018. The role of simulation-based training in FES skills test performance after this requirement has not been evaluated. METHODS: De-identified data from the initial FES skills tests after the Flexible Endoscopy Curriculum requirement was reviewed, and 731 unique participants with reported simulation experience demographics were identified. Self-reported data included sex, upper (UE) and lower (LE) endoscopy experience, and simulator training hours (SE). Final FES skills exam scores and pass/fail designations for each participant were reported by the FES program staff. RESULTS: There was a statistically discernible difference in mean FES total scores between those reporting no SE and more experienced groups ( P = 0.002), and between less and more experienced UE and LE groups ( P < 0.001). There was no statistically discernible difference in FES skills exam pass rates between SE groups ( P = 0.2), but there was a strong relationship between clinical experience (UE & LE) and pass rate ( P < 0.001). Finally, on logistic regression analysis, LE was a discernible predictor of passing [odds ratio (OR) = 1.4, 95% confidence interval (CI) 1.1-1.8, P = 0.02], while UE [odds ratio (OR) = 1, 95% CI 0.8-1.3, P = 0.9] and SE (OR = 1,95% CI 0.9- 1.3, P = 0.7) were not. CONCLUSIONS: There is no threat to the validity of the FES skills test from a need for simulation training to pass the FES skills test. Similarly, the amount of simulation practice is not predictive of passing, but can improve performance on certain FES tasks.

The Use of Learning Analytics to Enable Detection of Underperforming Trainees: An Analysis of National Vascular Surgery Trainee ACGME Milestones Assessment Data.

OBJECTIVE: This study aims to investigate at-risk scores of semiannual Accreditation Council for Graduate Medical Education (ACGME) Milestone ratings for vascular surgical trainees' final achievement of competency targets. SUMMARY BACKGROUND DATA: ACGME Milestones assessments have been collected since 2015 for Vascular Surgery. It is unclear whether milestone ratings throughout training predict achievement of recommended performance targets upon graduation. METHODS: National ACGME Milestones data were utilized for analyses. All trainees completing 2-year vascular surgery fellowships in June 2018 and 5-year integrated vascular surgery residencies in June 2019 were included. A generalized estimating equations model was used to obtain at-risk scores for each of the 31 subcompetencies by semiannual review periods, to estimate the probability of trainees achieving the recommended graduation target based on their previous ratings. RESULTS: A total of 122 vascular surgery fellows (VSFs) (95.3%) and 52 integrated vascular surgery residents (IVSRs) (100%) were included. VSFs and IVSRs did not achieve level 4.0 competency targets at a rate of 1.6% to 25.4% across subcompetencies, which was not significantly different between the 2 groups for any of the subcompetencies ( P = 0.161-0.999). Trainees were found to be at greater risk of not achieving competency targets when lower milestone ratings were assigned, and at later time-points in training. At a milestone rating of 2.5, with 1 year remaining before graduation, the at-risk score for not achieving the target level 4.0 milestone ranged from 2.9% to 77.9% for VSFs and 33.3% to 75.0% for IVSRs. CONCLUSION: The ACGME Milestones provide early diagnostic and predictive information for vascular surgery trainees' achievement of competence at completion of training.

The American College of Surgeons Entering Resident Readiness Assessment (ACS ERRA): Validity Evidence From a Three-Year National Study.

OBJECTIVE: To gather validity evidence supporting the use and interpretation of scores from the American College of Surgeons Entering Resident Readiness Assessment (ACS ERRA) Program. SUMMARY AND BACKGROUND DATA: ACS ERRA is an online formative assessment program developed to assess entering surgery residents' ability to make critical clinical decisions, and includes 12 clinical areas and 20 topics identified by a national panel of surgeon educators and residency program directors. METHODS: Data from 3 national testing administrations of ACS ERRA (2018-2020) were used to gather validity evidence regarding content, response process, internal structure (reliability), relations to other variables, and consequences. RESULTS: Over the 3 administrations, 1975 surgery residents participated from 125 distinct residency programs. Overall scores [Mean = 64% (SD = 7%)] remained consistent across the 3 years ( P = 0.670). There were no significant differences among resident characteristics (gender, age, international medical graduate status). The mean case discrimination index was 0.54 [SD = 0.15]. Kappa inter-rater reliability for scoring was 0.87; the overall test score reliability (G-coefficient) was 0.86 (Ф-coefficient = 0.83). Residents who completed residency readiness programs had higher ACS ERRA scores (66% versus 63%, Cohen's d = 0.23, P < 0.001). On average, 15% of decisions made (21/140 per test) involved potentially harmful actions. Variability in scores from graduating medical schools (7%) carried over twice as much weight than from matched residency programs (3%). CONCLUSIONS: ACS ERRA scores provide valuable information to entering surgery residents and surgery program directors to aid in development of individual and group learning plans.

Impact of a Virtual Professional Development Coaching Program on the Professional Fulfillment and Well-Being of Women Surgery Residents: A Randomized Controlled Trial.

OBJECTIVE: Evaluate the effect of a virtual coaching program offered to women surgery residents in a surgical society. BACKGROUND: Randomized controlled experiments evaluating the effect of coaching on trainee well-being and burnout is lacking. METHODS: Women surgery residents in the Association of Women Surgeons were recruited to participate in a randomized controlled trial of the effects of a virtual coaching program on trainee well-being. Attending surgeons served as coaches after completing in-person training. Residents (n=237) were randomized to intervention (three 1:1 coaching sessions over 9 mo) or control (e-mailed wellness resources). Participants were surveyed at baseline and postintervention using validated measures of well-being, burnout, and resilience. Changes in outcome measures between presurvey and postsurvey were compared between study arms. RESULTS: Survey response rates were 56.9% (n=66) in the control group and 69.4% (n=84) in the intervention group ( P =0.05). The intervention group showed significant improvement in professional fulfillment ( P =0.021), burnout (0.026), work exhaustion (0.017), self-valuation (0.003), and well-being ( P =0.002); whereas the control group showed significant improvement in self-valuation ( P =0.015) and significant decline in resilience ( P =0.025). The intervention group had a significant improvement in well-being ( P =0.015) and intolerance of uncertainty ( P =0.015) compared to controls. CONCLUSIONS: Women surgery residents who participated in a remote coaching program offered by a surgical society demonstrated improvement in aspects of well-being relative to peers who did not receive coaching. Therefore, remote coaching offered by a professional society may be a useful component of initiatives directed at trainee well-being.

Clinical utility of quantitative immunoassays and surrogate virus neutralization tests for predicting neutralizing activity against the SARS-CoV-2 Omicron BA.1 and BA.5 variants.

Developing new antibody assays for emerging SARS-CoV-2 variants is challenging. SARS-CoV-2 surrogate virus neutralization tests (sVNT) targeting Omicron BA.1 and BA.5 have been devised, but their performance needs to be validated in comparison with quantitative immunoassays. First, using 1749 PRNT-positive sera, we noticed that log-transformed optical density (OD) ratio of wild-type (WT) sVNT exhibited better titer-correlation with plaque reduction neutralization test (PRNT) than % inhibition value. Second, we tried 798 dilutional titration tests with 103 sera, but nonlinear correlation between OD ratio and antibody concentration limited titration of sVNT. Third, the titer-correlations of two sVNT kits for BA.1 and two quantitative immunoassays for WT were evaluated with BA.1 and BA.5 PRNT. All tested kits exhibited a linear correlation with PRNT titers, but the sVNT kits exhibited high false-negative rates (cPass-BA.1 kit, 45.4% for BA.1 and 44.2% for BA.5; STANDARD F-BA.1 kit, 1.9% for BA.1 and 2.2% for BA.5), while quantitative immunoassays showed 100% sensitivity. Linear mixed-effects model suggested superior titer-correlation with PRNT for quantitative immunoassays compared to sVNT kits. Taken together, the use of quantitative immunoassays for WT, rather than rapid development of new kits, would be practical for predicting neutralizing activities against emerging new variants.

Learning transfusion medicine through scoring objective structured clinical examination.

BACKGROUND: Transfusion medicine education at the undergraduate level is typically limited in duration. In view of limitations of traditional teaching methods, we explore effectiveness of scoring (Objective Structured Clinical Examination) OSCE as an educational method. MATERIALS AND METHODS: The study was of a randomized interventional three group pre-test-post-test design. Participants were undergraduate medical students in their two final years. The intervention was watching and scoring 2 videotaped OSCE stations about obtaining consent for blood transfusions and assessing the ability to explain risks, benefits, and alternatives of blood transfusion. Participants were asked to assess the performance of the videotaped actor using checklists. Participants were randomized to watch and evaluate one set of videos at either the highest, intermediate, or lowest compliance with required consent elements. Main measure was performance in a knowledge test containing multiple-choice and true/false questions. This was given before (pre-test), immediately after the intervention (post-test 1), and after 8 weeks (post-test 2). Student perceptions regarding the intervention was assessed immediately after the session. RESULTS: Sixty-nine students were randomized. Post-test 1 results (mean 16.52, SD 1.88) were significantly greater than pre-test results (mean 11.83, SD 2.13) by group and across all groups (p < 0.001). Post-test 2 results for the complete cohort showed maintenance of significant improvement in comparison with the pre-test. The majority of students agreed that learning through scoring OSCE was an effective educational experience. CONCLUSIONS: In the undergraduate medical setting, scoring OSCE stations may enhance learning of content discussed and evaluated in the stations.

The Epidemiological and Clinical Characteristics of the Largest Outbreak of Enterohemorrhagic Escherichia coli in Korea.

BACKGROUND: The largest outbreak of enterohemorrhagic Escherichia coli (EHEC) O157:H7 occurred at a preschool in South Korea from June 12 to 29, 2020. This study aimed to analyze the epidemiological and clinical characteristics of EHEC infection in this outbreak. METHODS: Epidemiological investigation was performed on all 184 children and 19 workers at the preschool using a standard questionnaire to assess symptoms, food intake, attendance, and special activity history. Pulsed-field gel electrophoresis analysis of confirmed cases was performed to determine genetic relevance. RESULTS: During this outbreak, 103 children were affected, whereas only one infection was identified in adults. Of the 103 pediatric patients, 85 had symptoms (82.5%), including diarrhea, abdominal pain, bloody stool, fever, and vomiting. Thirty-two patients (31.1%) were hospitalized, 15 (14.6%) were diagnosed with hemolytic uremic syndrome, and 4 (3.9%) received dialysis treatment. Pulsed-field gel electrophoresis analysis identified 4 genotypes with high genetic relevance (92.3%). Epidemiological investigation revealed that this outbreak might have occurred from ingesting foods stored in a refrigerator with a constant temperature above 10°C, which was conducive to bacterial growth. Despite several measures after outbreak recognition, new infections continued to appear. Therefore, the preschool was forced to close on June 19 to prevent further person-to-person transmission. CONCLUSION: Our findings from the response to the largest outbreak will help prepare countermeasures against future EHEC outbreak.

Vaccine Effect on Household Transmission of Omicron and Delta SARS-CoV-2 Variants.

BACKGROUND: We evaluated the household secondary attack rate (SAR) of the omicron and delta severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants, according to the vaccination status of the index case and household contacts; further, in vaccinated index cases, we evaluated the effect of the antibody levels on household transmission. METHODS: A prospective cross-sectional study of 92 index cases and 197 quarantined household contacts was performed. Tests for SARS-CoV-2 variant type and antibody level were conducted in index cases, and results of polymerase chain reaction tests (during the quarantine period) were collected from contacts. Association of antibody levels in vaccinated index cases and SAR was evaluated by multivariate regression analysis. RESULTS: The SAR was higher in households exposed to omicron variant (42%) than in those exposed to delta variant (27%) (P = 0.040). SAR was 35% and 23% for unvaccinated and vaccinated delta variant exposed contacts, respectively. SAR was 44% and 41% for unvaccinated and vaccinated omicron exposed contacts, respectively. Booster dose immunisation of contacts or vaccination of index cases reduced SAR of vaccinated omicron variant exposed contacts. In a model with adjustment, anti-receptor-binding domain antibody levels in vaccinated index cases were inversely correlated with household transmission of both delta and omicron variants. Neutralising antibody levels had a similar relationship. CONCLUSION: Immunisation of household members may help to mitigate the current pandemic.

Surgical skills training for practicing surgeons founded on established educational theories and frameworks.

Following completion of structured training in residency or fellowship programs, surgeons need to acquire new skills throughout their careers to address changes in their surgical practices, and to perform new procedures and use new technologies as these are developed. The opportunities available to surgeons to acquire the new skills, safely introduce these skills into surgical practice, and then maintain the skills, vary greatly and may not fully support a surgeon's needs. The article shares background information relating to the vexing problems, and describes established educational theories and frameworks as well as specific frameworks relating to surgical skills training and verification that may be used in designing and implementing comprehensive and impactful surgical skills training programs aimed at practicing surgeons. A number of practical strategies based on these theories and frameworks are highlighted. National professional organizations and academic medical centers need to play a critical role in pursuing such efforts, which will remain pivotal in supporting the professional work of surgeons and in providing optimal surgical care well into the future.

The test developer's dilemma: Evaluating the balance of feasibility and empiric performance of test development techniques for repeated written assessments.

PURPOSE: Written assessments face challenges when administered repeatedly, including resource-intensive item development and the potential for performance improvement secondary to item recall as opposed to understanding. This study examines the efficacy of three-item development techniques in addressing these challenges. METHODS: Learners at five training programs completed two 60-item repeated assessments. Items from the first test were randomized to one of three treatments for the second assessment: (1) Verbatim repetition, (2) Isomorphic changes, or (3) Total revisions. Primary outcomes were the stability of item psychometrics across test versions and evidence of item recall influencing performance as measured by the rate of items answered correctly and then incorrectly (correct-to-incorrect rate), which suggests guessing. RESULTS: Forty-six learners completed both tests. Item psychometrics were comparable across test versions. Correct-to-incorrect rates differed significantly between groups with the highest guessing rate (lowest recall effect) in the Total Revision group (0.15) and the lowest guessing rate (highest recall effect) in the Verbatim group (0.05), p = 0.01. CONCLUSIONS: Isomorphic and total revisions demonstrated superior performance in mitigating the effect of recall on repeated assessments. Given the high costs of total item revisions, there is promise in exploring isomorphic items as an efficient and effective approach to repeated written assessments.[Box: see text].

Patient handoffs and multi-specialty trainee perspectives across an institution: informing recommendations for health systems and an expanded conceptual framework for handoffs.

BACKGROUND: Safe and effective physician-to-physician patient handoffs are integral to patient safety. Unfortunately, poor handoffs continue to be a major cause of medical errors. Developing a better understanding of challenges faced by health care providers is critical to address this continued patient safety threat. This study addresses the gap in the literature exploring broad, cross-specialty trainee perspectives around handoffs and provides a set of trainee-informed recommendations for both training programs and institutions. METHODS: Using a constructivist paradigm, the authors conducted a concurrent/embedded mixed method study to investigate trainees' experiences with patient handoffs across Stanford University Hospital, a large academic medical center. The authors designed and administered a survey instrument including Likert-style and open-ended questions to solicit information about trainee experiences from multiple specialties. The authors performed a thematic analysis of open-ended responses. RESULTS: 687/1138 (60.4%) of residents and fellows responded to the survey, representing 46 training programs and over 30 specialties. There was wide variability in handoff content and process, most notably code status not being consistently mentioned a third of the time for patients who were not full code. Supervision and feedback about handoffs were inconsistently provided. Trainees identified multiple health-systems level issues that complicated handoffs and suggested solutions to these threats. Our thematic analysis identified five important aspects of handoffs: (1) handoff elements, (2) health-systems-level factors, (3) impact of the handoff, (4) agency (duty), and (5) blame and shame. CONCLUSIONS: Health systems, interpersonal, and intrapersonal issues affect handoff communication. The authors propose an expanded theoretical framework for effective patient handoffs and provide a set of trainee-informed recommendations for training programs and sponsoring institutions. Cultural and health-systems issues must be prioritized and addressed, as an undercurrent of blame and shame permeates the clinical environment.

Exploring gender and thematic differences in qualitative assessments of internal medicine resident performance.

INTRODUCTION: Evidence suggests gender disparities in medical education assessment, including differences in ratings of competency and narrative comments provided in resident performance assessments. This study explores how gender manifests within the content of qualitative assessments (i.e., narrative comments or performance feedback) of resident performance. METHODS: Qualitative content analysis was used to explore gender-based differences in narrative comments included in faculty assessments of resident performance during inpatient medicine rotations at six Internal Medicine residency programs, 2016-2017. A blinded, multi-analyst approach was employed to identify themes across comments. Patterns in themes with resident gender and post-graduate year (PGY) were explored, focusing on PGY2 and PGY3 when residents are serving in the team leader role. RESULTS: Data included 3,383 evaluations with narrative comments of 385 men (55.2%) and 313 women residents (44.8%). There were thematic differences in narrative comments received by men and women residents and how these themes manifested within comments changed with training time. Compared to men, comments about women had a persistent relationship-orientation and emphasized confidence over training including as interns and in PGY2 and PGY3, when serving as team leader. The relationship-orientation was characterized not only by the residents' communal attributes but also their interpersonal and communication skills, including efforts supporting others and establishing the tone for the team. Comments about women residents often highlighted confidence, including recommendations around behaviors that convey confidence in decision-making and team leadership. DISCUSSION: There were gender-based thematic differences in qualitative assessments. Comments about women resident team leaders highlight relationship building skills and urge confidence and actions that convey confidence as team leader. Persistent attention to communal skills suggests gendered expectations for women resident team leaders and a lost opportunity for well-rounded feedback to the disadvantage of women residents. These findings may inform interventions to promote equitable assessment, such as providing feedback across the competencies.
