Background:
Although gender-affirming hormone therapy (GAHT) can be safely prescribed in primary care settings, many primary care providers (PCPs) feel unprepared to do so for transgender and gender-diverse (trans) patients.
Objective:
To evaluate and compare two brief educational interventions for changing attitudes, knowledge, and likelihood to prescribe GAHT for trans patients.
Design:
Randomized controlled trial PARTICIPANTS: Internal Medicine residents with a primary care clinic MAIN MEASURES: Surveys measuring attitudes pertaining to care for trans patients (e.g., Transphobia scale, range of 1-7), 20-item knowledge assessment, six-item clinical self-assessment, and two-item self-reported likelihood to prescribe GAHT (1-7 scale).
Key Results:
Of 1596 eligible residents, 623 (39.0%) were included in the analysis. Transphobia scores were low at baseline (mean = 2.09, SD = 0.90). Transphobia decreased in both the clinical and cultural arms from 2.07 to 1.78 (p < 0.001) and from 2.11 to 1.81 (p < 0.001), respectively. At baseline, residents had a higher likelihood to continue a patient's GAHT prescription (mean = 5.26, SD = 1.68) than to start a patient on GAHT (mean = 3.55, SD = 1.71). After watching the webinars, both arms were statistically significantly more likely to continue GAHT (mean = 5.66, SD = 1.48) and start GAHT (mean = 4.29, SD = 1.73). Knowledge scores and comfort addressing health care needs of trans patients were greater in the clinical arm; there were no other differences in changes between the two randomized groups.
Conclusions:
We found that brief educational videos had measurable effects on attitudes and likelihood to prescribe GAHT in IM resident PCPs. Addressing clinical knowledge gaps may be a more efficient way to achieve these results than focusing on cultural competency.
