About
Dr. Emi Hayashi is a health services researcher whose work illuminates critical disparities in surgical care, particularly in gynecologic procedures. Her most cited study, "Geographic Variance of Cost Associated With Hysterectomy" (2017, 16 citations), established her as a key voice in understanding how location drives healthcare economics. Using the 2013 Healthcare Cost and Utilization Project National Inpatient Sample, Hayashi demonstrated that the cost of benign hysterectomy varies significantly across U.S. regions—a finding with direct implications for policy, hospital reimbursement, and patient access. This cross-sectional, population-based analysis exemplifies her commitment to leveraging large-scale administrative data to reveal systemic inequities. While her citation count is modest, the study’s practical relevance has made it a touchstone for researchers examining cost variation in women’s health. Hayashi’s work bridges clinical gynecology and health economics, offering actionable insights for reducing unwarranted spending without compromising care quality. Her research continues to inform value-based care models, making her a rising authority on the intersection of surgical outcomes, cost, and geography.
