Trends in United States neurosurgery residency education and training over the last decade (2009–2019)

Abstract

OBJECTIVEPostgraduate training in medicine has been under scrutiny in the last 10 years, with a focus on improving residents’ education. The aim of this study was to quantify trends in neurosurgery residency (NSR) training and education over the last 10 years.METHODSThe authors assessed Accreditation Council for Graduate Medical Education (ACGME), National Resident Matching Program, and American Board of Neurological Surgeons records and searched PubMed to collate 2009–2019 data. Analyzed trends included residents’ demographic data, programs’ characteristics, graduation and attrition rates, match data, resident case logs, and qualitative educational curriculum changes.RESULTSSignificant increases in residents’ demographic data (p < 0.05) included the number of female residents (from 12.7% to 17.6%) and the absolute number of residents (from 1112 to 1462). Age (mean 28.8 years), ethnicity, and number of residents per program (mean 13 residents per program) were unchanged. There were 16 new ACGME NSR programs, with currently 115 programs nationwide. The number of applicants per year (324 applicants per year) and the matching rate (mean 64%) remained stable. The mean attrition rate of 2.6% (range 2%–4%) was higher than the mean 2.1% ACGME attrition rate, a rate that decreased from 3% in 2009 to 1.6% in 2019. Education curriculum changes aimed at the standardization of training across the US included residents’ boot camp (2009), the Milestones project (2012), and mandatory 7-year training initiated in 2013. An increase in endovascular, functional, trauma, and spine resident caseload was noted. The number of yearly publications about US NSR education has significantly increased (p < 0.05).CONCLUSIONSNSR education has received greater attention over the last decade in the US. Standardization of training has been implemented. A steady number of students remain interested in neurosurgery, with an increased number of women entering the field. Attention to wellness, in addition to high-quality education, should be further assessed as a factor to improve the overall NSR training and retention rate.
