Faculty Scoring of General Surgery Residency Interviewees: A Comparison of In-Person and Virtual Interview Formats.

OBJECTIVE: With new rules regarding social distancing and non-essential travel bans, we sought to determine if faculty scoring of general surgery applicants would differ between the in-person interview (IPI) and virtual interview (VI) platforms. DESIGN: A single institution, retrospective review comparing faculty evaluation scores of applicant interviewees in the 2019 and 2020 MATCH® application cycles (IPIs) and the 2021 and 2022 application cycle (VIs) was conducted. Faculty scored applicants using a 5-point Likert scale in 7 areas of assessment and assigned each student to 1 of 4 tiers (tier 1 highest). A composite score for the 7 assessments (maximum score 35) was calculated. Mean and composite scores and tiers were compared between VI and IPI cycles and adjusted for within-interviewer correlations. The variance of the 2 groups were also compared. SETTING: Harbor-UCLA Medical Center, an academic, tertiary care hospital. PARTICIPANTS: General Surgery applicants for the 2019 to 2022 MATCH® application cycles. RESULTS: Four hundred forty-one faculty IPI ratings of General Surgery applicants were compared to 531VI ratings. No difference in mean composite scores, individual assessments, or tier ranking. Less variance was identified in the VI group for academic credentials (0.6 vs 0.6, p = 0.01), strength of letters (0.7 vs 0.4, p = 0.005), communication skills (0.4 vs 0.6, p = 0.01), personal qualities (0.2 vs 0.5, p = 0.02), overall sense of fit for program (0.6 vs 0.9, p = 0.01), and tier ranking (0.3 vs 0.4, p = 0.004). CONCLUSIONS: Faculty ratings of General Surgery applicants in the VI format appear to be similar to IPI. However, faculty ratings of VI applicants demonstrated less variability in scores in most assessments. This finding is potentially concerning, as it may suggest an inability of VI to detect subtle differences between applicants as comparted to IPI.

Anti-Xa-guided enoxaparin thromboprophylaxis reduces rate of deep venous thromboembolism in high-risk trauma patients.

BACKGROUND: Appropriate prophylaxis against venous thromboembolism (VTE) remains undefined. This study evaluated an anti-Xa-guided enoxaparin thromboprophylaxis (TPX) protocol on the incidence of VTE in high-risk trauma patients based on Greenfield's Risk Assessment Profile (RAP) score. METHODS: This is a retrospective observational study of patients admitted to a trauma intensive care unit over a 12-month period. Patients were included if they received anti-Xa-guided enoxaparin TPX. Dosage was adjusted to a prophylactic peak anti-Xa level of 0.2 to 0.4 IU/mL. Subgroup analysis was performed on high-risk patients (RAP score ≥10) who received lower-extremity duplex ultrasound surveillance for deep vein thrombosis (DVT). Data are expressed as mean ± SD. Significance was assessed at p < 0.05. RESULTS: One hundred thirty-one patients received anti-Xa-guided enoxaparin TPX. Four patients were excluded for age or acute VTE on admission. Fifty-six patients with RAP score of ≥10 and surveillance duplex evaluations were included in the subgroup analysis with mean age 43 ± 20 years, Injury Severity Score of 25 ± 10, and RAP score of 16 ± 4. Prophylactic anti-Xa levels were initially achieved in 34.6% of patients. An additional 25.2% required 40 to 60 mg twice daily to reach prophylactic levels; 39.4% never reached prophylactic levels. Weight, body mass index, ISS, and RAP score were significantly higher with subprophylactic anti-Xa levels. One patient developed bleeding complications (0.8%). No patient developed intracerebral bleeding or heparin-induced thrombocytopenia.Nine VTE events occurred in the high-risk subgroup, including four DVT (7.1%), all asymptomatic, and five pulmonary emboli (8.9%). The historical rate of DVT in similar patients (ISS 31 ± 12 and RAP score 16 ± 5) was 20.5%, a significant decrease (p = 0.031). Mean chest Abbreviated Injury Scale scores were significantly higher for patients developing pulmonary emboli than DVT, 3.0 ± 1.1 vs. 0.0 (p < 0.001). CONCLUSIONS: Mean chest Abbreviated Injury Scale score was higher in patients developing pulmonary embolism. Increased weight, body mass index, ISS, and RAP score are associated with subprophylactic anti-Xa levels. Anti-Xa-guided enoxaparin dosing reduced the rate of DVT from 20.5% to 7.1% in high-risk trauma patients. LEVEL OF EVIDENCE: Therapeutic study, level IV.
