They disproportionately disadvantage applicants without access to robust research infrastructure, compress timelines, incentivize low-impact output, and contribute to anxiety and burnout. We propose a framework to realign incentives toward rigor, equity, and clinical relevance. Key recommendations include adopting quality-weighted scoring systems for scholarly work (e.g., the evolving Arms Race Control Score), capping the number of research items applicants may report, and requiring concise statements that define an applicant's scholarly trajectory. Additional measures include formally recognizing impactful nontraditional contributions (e.g., quality improvement projects, open-source tools, patents, device innovations), piloting objective assessments relevant to neurosurgery (such as simulation-based surgical skills and standardized subinternship milestones), and committing to longitudinal research evaluating whether pre-residency publications predict training and career outcomes. Implemented collectively and supported by shared program director guidelines, these reforms could shift focus from publication counts to meaningful scholarship, preserve opportunities for late-deciding applicants and those at less-resourced institutions, and strengthen the scientific foundation of residency selection.

Here, we compare the safety and efficacy of combining a direct oral anticoagulant (DOAC) with clopidogrel vs aspirin with clopidogrel in patients undergoing CAS.</p><p><strong>Methods: </strong>We conducted a retrospective cohort comparison study of 469 consecutive patients with carotid artery stenosis who underwent CAS and were prescribed either a DOAC plus clopidogrel or aspirin plus clopidogrel. Propensity scores were generated based on baseline characteristics with an absolute standardized difference of ≥0.20 between cohorts. Patients were matched in a 1:1 ratio using propensity score matching based on the calculated propensity scores. Safety and efficacy outcomes were compared.</p><p><strong>Results: </strong>The study cohort consisted of 419 patients treated with aspirin and clopidogrel and 50 patients treated with a DOAC and clopidogrel. There was no significant difference in the primary safety outcome, total periprocedural complication rate, between cohorts before and after matching. Overall bleeding complications through femoral access were significantly lower in the DOAC plus clopidogrel group after matching (0.0% vs 11.4%, P = .043). Additional secondary safety outcomes and all efficacy outcomes (symptomatic in-stent stenosis, total in-stent stenosis, and retreatment) were not significantly different between groups.</p><p><strong>Conclusion: </strong>In this study, we found that a DOAC plus clopidogrel exhibits similar safety and efficacy profiles as compared with aspirin plus clopidogrel for patients undergoing CAS. Although bleeding complications through femoral access were significantly lower in the DOAC plus clopidogrel group, further studies are needed to clarify this finding.</p>","PeriodicalId":19276,"journal":{"name":"Neurosurgery","volume":" ","pages":"861-872"},"PeriodicalIF":3.8,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146011313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
