Effectiveness of undergraduate medical students training on LGBTQIA + people health: a systematic review and meta-analysis

Adequacy of learning models and their ability to engage students and match session’s objectives are critical factors in achieving the desired outcome. In this systematic review and meta-analysis, we assess the methodological approach, content, and effectiveness of training initiatives addressing medical students’ knowledge, attitudes, confidence and discrimination perception towards LGBTQIA + people.

PubMed, Web of Science, Medline and Scopus were searched to identify published studies, from 2013 to 2023, on effectiveness of training initiatives addressing medical students’ knowledge, attitudes, confidence and discrimination perception towards LGBTQIA + people. The risk of bias of the selected studies was assessed by the Medical Education Research Study Quality Instrument. Overall effect sizes were calculated using a Mantel–Haenszel method, fixed effect meta-analyses.

A total of 22 studies were included, representing 2,164 medical students. The interventions were highly diverse and included seminars, lectures, videos, real-case discussions, roleplay, and group discussions with people from the LGBTQIA + community. After the interventions, there was a significant improvement in self-confidence and comfort interacting with patients and in the understanding of the unique and specific health concerns experienced by LGBTQIA + patients.

Our findings indicated that the outcomes of interventions training actions for medical students that promote knowledge and equity regarding LGBTQIA + people, regardless of their scope, methodology and duration, result in a considerable increase in students’ self-confidence and comfort interacting with LGBTQIA + patients, highlight the need for more actions and programs in this area promoting a more inclusive society and greater equity.
