ALT We surveyed 1,684 people who are transgender, nonbinary, or gender-expansive (TGE) and assigned female at birth to learn about their experiences with healthcare providers. 70% of participants reported at least one negative experience with a healthcare provider in the past year.The most common experiences: being negatively affected by a provider's opinions about LGBTQIA+ identities, and having to educate a healthcare provider about TGE identities to receive proper medical care.Those who received gender-affirming care were more likely to report negative experiences with healthcare providers than those who hadn't. Among people who did not receive gender-affirming care, those who were out about their TGE identity to their healthcare provider were more likely to report negative experiences. This is one of the first studies with a large number of participants to look at the relationship between receiving gender-affirming care and negative interactions with healthcare providers.
