Trust Me, I Know Them: Assessing Interpersonal Bias in Surgery Residency Interviews.

Background: Residency selection integrates objective and subjective data sources. Interviews help assess characteristics like insight and communication but have the potential for bias. Structured multiple mini-interviews may mitigate some elements of bias; however, a halo effect is described in assessments of medical trainees, and degree of familiarity with applicants may remain a source of bias in interviews. Objective: To investigate the extent of interviewer bias that results from pre-interview knowledge of the applicant by comparing file review and interview scores for known versus unknown applicants. Methods: File review and interview scores of applicants to the University of Ottawa General Surgery Residency Training Program from 2019 to 2021 were gathered retrospectively. Applicants were categorized as "home" if from the institution, "known" if they completed an elective at the institution, or "unknown." The Kruskal-Wallis H test was used to compare median interview scores between groups and Spearman's rank-order correlation (rs) to determine the correlation between file review and interview scores. Results: Over a 3-year period, 169 applicants were interviewed; 62% were unknown, 31% were known, and 6% were home applicants. There was a statistically significant difference (P=.01) between the median interview scores of home, known, and unknown applicants. Comparison of groups demonstrated higher positive correlations between file review and interview scores (rs=0.15 vs 0.36 vs 0.55 in unknown, known, and home applicants) with increasing applicant familiarity. Conclusions: There is an increased positive correlation between file review and interview scores with applicant familiarity. The interview process may carry inherent bias insufficiently mitigated by the current structure.

Comparing 2 Approaches for the File Review of Residency Applications.

BACKGROUND: The residency selection process relies on subjective information in applications, as well as subjective assessment of applications by reviewers. This inherent subjectivity makes residency selection prone to poor reliability between those reviewing files. OBJECTIVES: We compared the interrater reliability of 2 assessment tools during file review: one rating applicant traits (ie, leadership, communication) and the other using a global rating of application elements (ie, curriculum vitae, reference letters). METHODS: Ten file reviewers were randomized into 2 groups, and each scored 7 general surgery applications from the 2019-2020 cycle. The first group used an element-based (EB) scoring tool, while the second group used a trait-based (TB) scoring tool. Feedback was collected, discrimination capacities were measured using variation in scores, and interrater reliability (IRR) was calculated using intraclass correlation (ICC) in a 2-way random effects model. RESULTS: Both tools identified the same top-ranked and bottom-ranked applicants; however, discrepancies were noted for middle-ranked applicants. The score range for the 5 middle-ranked applicants was greater with the TB tool (6.43 vs 3.80), which also demonstrated fewer tie scores. The IRR for TB scoring was superior to EB scoring (ICC [2, 5] = 0.82 vs 0.55). The TB tool required only 2 raters to achieve an ICC ≥ 0.70. CONCLUSIONS: Using a TB file review strategy can facilitate file review with improved reliability compared to EB, and a greater spread of candidate scores. TB file review potentially offers programs a feasible way to optimize and reflect their institution's core values in the process.

Everyone Is Awesome: Analyzing Letters of Reference in a General Surgery Residency Selection Process.

BACKGROUND: The resident selection process involves the analysis of multiple data points, including letters of reference (LORs), which are inherently subjective in nature. OBJECTIVE: We assessed the frequency with which LORs use quantitative terms to describe applicants and to assess whether the use of these terms reflects the ranking of trainees in the final selection process. METHODS: A descriptive study analyzing LORs submitted by Canadian medical graduate applicants to the University of Ottawa General Surgery Program in 2019 was completed. We collected demographic information about applicants and referees and recorded the use of preidentified quantitative descriptors (eg, best, above average). A 10% audit of the data was performed. Descriptive statistics were used to analyze the demographics of our letters as well as the frequency of use of the quantitative descriptors. RESULTS: Three hundred forty-three LORs for 114 applicants were analyzed. Eighty-five percent (291 of 343) of LORs used quantitative descriptors. Eighty-four percent (95 of 113) of applicants were described as above average, and 45% (51 of 113) were described as the "best" by at least 1 letter. The candidates described as the "best" ranked anywhere from second to 108th in our ranking system. CONCLUSIONS: Most LORs use quantitative descriptors. These terms are generally positive, and while the use does discriminate between different applicants, it was not helpful in the context of ranking applicants in our file review process.

Prioritizing resident and patient safety while maintaining educational value: emergency restructuring of a Canadian surgical residency program during COVID-19.

Summary: Surgical programs are facing major and fluctuating changes to the resident workforce because of decreased elective volumes and high exposure risk during the coronavirus disease 2019 pandemic. Rapid restructuring of a residency program to protect its workforce while maintaining educational value is imperative. We describe the experience of the Division of General Surgery at the University of Ottawa in Ontario, Canada. The residency program was restructured to feature alternating "on" and "off" weeks, maintaining a healthy resident cohort in case of exposure. Teams were restructured and subdivided to maximize physical distancing and minimize resident exposure to pathogens. Educational initiatives doubled, with virtual sessions targeting every resident year and incorporating intraoperative teaching. The divisional research day and oral exams proceeded uninterrupted, virtually. A small leadership team enabled fast and flexible restructuring of a system for patient care while prioritizing resident safety and maintaining a commitment to resident education in a pandemic.

Nephropathy and elevated BP in mice with podocyte-specific NADPH oxidase 5 expression.

NADPH oxidase (Nox) enzymes are a significant source of reactive oxygen species, which contribute to glomerular podocyte dysfunction. Although studies have implicated Nox1, -2, and -4 in several glomerulopathies, including diabetic nephropathy, little is known regarding the role of Nox5 in this context. We examined Nox5 expression and regulation in kidney biopsies from diabetic patients, cultured human podocytes, and a novel mouse model. Nox5 expression increased in human diabetic glomeruli compared with nondiabetic glomeruli. Stimulation with angiotensin II upregulated Nox5 expression in human podocyte cultures and increased reactive oxygen species generation. siRNA-mediated Nox5 knockdown inhibited angiotensin II-stimulated production of reactive oxygen species and altered podocyte cytoskeletal dynamics, resulting in an Rac-mediated motile phenotype. Because the Nox5 gene is absent in rodents, we generated transgenic mice expressing human Nox5 in a podocyte-specific manner (Nox5(pod+)). Nox5(pod+) mice exhibited early onset albuminuria, podocyte foot process effacement, and elevated systolic BP. Subjecting Nox5(pod+) mice to streptozotocin-induced diabetes further exacerbated these changes. Our data show that renal Nox5 is upregulated in human diabetic nephropathy and may alter filtration barrier function and systolic BP through the production of reactive oxygen species. These findings provide the first evidence that podocyte Nox5 has an important role in impaired renal function and hypertension.
