"I Think There's Only Two Fields for That": Hospital Registrar Attitudes and Practices for Collecting Patient Gender Identity Data.

Purpose: This study aimed to understand the experiences of hospital registrars in collecting gender identity data.

Methods: A qualitative study that thematically analyzed key informant interviews with 37 registrars regarding their attitudes and practices in collecting gender identity data.

Results: Collection of gender identity is influenced by (1) system-level barriers, (2) discrepancies in source of truth for documentation, and (3) registrars' underlying attitudes and behaviors.

Conclusions: Findings demonstrate that person- and system-level barriers can interfere with the accurate and respectful collection of gender identity data, which is critical for tracking and addressing lesbian, gay, bisexual, transgender, and queer health disparities.
