National Trends in Gender-Affirming Surgical Procedures: A Google Trends Analysis

Background: There has been a significant increase in the volume of gender-affirming surgical (GAS) procedures over the past decade. The objective of this paper is to use online search data from Google Trends (GT) to describe national search trends for GAS procedures. Methods: GT was queried for search terms relating to GAS from January 2004 to February 2021. The 19 selected keywords covered a broad range of GAS topics. United States (US) search interest was collected as relative search volumes (RSVs) and then analyzed by geographic region. The number of plastic surgery providers offering GAS and academic surgery centers was collected from the World Professional Association for Transgender Health (WPATH) and Trans-health.com. RSVs were analyzed by metro area to determine the relationship between search demand and personal income. State Medicaid policies for transgender health services were also collected. Results: All search terms demonstrated a positive increase in RSVs over time except “sex reassignment surgery” and “penectomy”. The Mountain/Pacific and East South Central/West South Central had the greatest search volume for GAS and most providers offering care. The East South Central/West South Central region​​ ranked last for providers offering care, despite the relatively high search interest. This region also had no states with explicit Medicaid policies covering gender-affirming care. Metro areas in the top five for RSV but bottom quartile for per capita personal income were identified. Conclusions: Online search interest for GAS-related terms has increased. Search interest for GAS has regional variation and did not show a specific pattern with provider availability.
