The neurosurgery residency applicant selection process is complex, with peer-reviewed publications (PRP) recently becoming a key focus. While PRP may significantly impact applicant matching, equitable opportunities for research may vary for students. We aimed to evaluate the impact of NIH funding and program reputation score on applicants' ability to match into top neurosurgery residency programs. Successfully matched PGY1 neurosurgery applicants in the 2022-2023 cycle were evaluated. PRP, Blue Ridge Institute for Medical Research (BRIMR) medical school and residency NIH-funding ranking, and residency Doximity reputation score were evaluated. PGY1 residents (n = 235, 73% male) included 84% MDs, 1.0% DO, 10% MD/PhD, and 5% IMGs. Thirty-one (13.2%) superpublishers (> 25 PRPs) were identified (93.5% male) and had a higher number of non-MD degrees (32.3% vs. 13.3%, p = 0.007). Matching into a top 20 NIH-ranked residency program was associated with completion of a top 20 NIH-medical program (OR = 2.70, p = 0.015), superpublisher status (OR = 2.87, p = 0.024), and affiliation with a top 40 NIH-ranked neurosurgery program (OR = 3.44, p < 0.001). Matching into a top 40 reputation program was predicted by being a superpublisher (≥ 25 publications; OR = 2.66, p = 0.04) and attending a medical school with an affiliated top 40 reputation neurosurgery program (OR = 4.85, p < 0.001). PRP has become a large focus in determining a candidate's competitiveness for top neurosurgery residency programs. Our results clarify the factors impacting PRP, including the importance of NIH funding and the neurosurgery department's reputation. These results highlight both best practices for training residents and potential disadvantages some medical school candidates may have from lower-ranked programs or limited research opportunities. Further studies are warranted to evaluate the impact of these factors on the equity of neurosurgery residency candidates.
