Transgender and gender nonbinary (trans/NB) people can face discriminatory behaviors when accessing health care services. Trans/NB patients were interviewed about their experiences accessing care in emergency departments. Four themes were uncovered: 1) system and structural issues; 2) interactions with clinicians/staff; 3) perceptions of clinician knowledge and education; and 4) impact on future health and healthcare access. Recommendations for improvement were provided at the system and clinician level.
