Characterizing Substance Use Disorders Among Transgender Adults Receiving Care at a Large Urban Safety Net Hospital.

OBJECTIVES:In the midst of the opioid crisis, increasing attention has been given to assessing and addressing substance use disorders (SUDs) among transgender and gender diverse (TGD) populations. As electronic health records begin to more uniformly collect gender identity data, clinicians and public health professionals are better able to examine the prevalence of SUDs and the receipt of SUD treatment services in these populations. METHODS:We utilized cross-sectional electronic health records data from January 2005 to December 2019 from a large safety-net hospital in Massachusetts. A cohort of TGD patients was identified using self-reported gender identity data as well as diagnostic and procedures codes associated with receipt of gender-affirming care (n = 2000). We calculated odds of SUD diagnosis and receipt of medications for SUD among TGD patients. RESULTS:Among a cohort of 2000 TGD patients, 8.8% had a SUD diagnosis. SUD diagnoses were more common among older, Black, and transmasculine patients, as well as those holding public health insurance. SUD diagnoses were less likely among those reporting college-level education. Of those with an opioid use disorder (OUD), 46% were prescribed an FDA-approved medication for OUD. CONCLUSIONS:SUD diagnoses among TGD patients were associated with demographic, socioeconomic, and gender-related factors. We found a modestly lower prevalence of non-tobacco SUD among our cohort of TGD patients than the national average of 7.4%. Despite a relatively better receipt of prescription treatment services than the national average, the low rate of treatment overall represents a missed opportunity to address SUDs in these vulnerable populations.
