Background:
Transgender and gender nonconforming (TGNC) individuals experience incongruence between their self-identified gender versus their birth-assigned sex. In some cases, TGNC patients undergo gender-affirming surgical (GAS) procedures. Although GAS is an evolving surgical field, there is currently limited literature documenting patient characteristics and procedures. Addressing this knowledge gap, this retrospective cohort analysis described the characteristics of New York State's TGNC residents with gender dysphoria (GD) diagnosis, including patients undergoing at least one gender-affirming surgical procedure.
Methods:
Using the New York Statewide Planning and Research Cooperative System (SPARCS) database from 2002 to 2018, we identified patients' first-time TCNC records and their risk characteristics. Patients who received GAS procedures were sub-classified as top-only, bottom-only, or combined top/bottom procedures and were compared with TGNC patients who did not receive GAS.
Results:
Of 24,615 records extracted from TGNC SPARCS database, 11,427 (46.4%) were transmasculine (female-to-male) and 13,188 (53.6%) were transfeminine (male-to-female). Overall, 2.73% of transgender patients received at least one GAS procedure. Of these patients, 78.2% had masculinizing and 21.8% had feminizing surgeries. After a diagnosis of GD, the positive predictors for a GAS-based procedure included female birth sex, pediatric age (<18 years) or older age (60+ years), commercial insurance coverage, and Hispanic race. In contrast, negative GAS predictors included male birth sex and government insurance coverage (i.e., Medicare and Medicaid).
Conclusions:
Compared with transgender women, transgender men were more likely to receive at least one GAS procedure. Because the race, ethnicity, and payor status of TGNC patients can impact GAS treatment rates, additional research is warranted to examine post-diagnosis GAS treatment disparities among TGNC patients.
