“…The most commonly reported barrier related to the training interventions was lack of appropriate educational materials (Park & Safer, 2018 ; Rosendale & Josephson, 2017 ; Vance et al, 2020 , 2021 ). Facilitation-related barriers primarily centered around the lack of expertise or experience among faculty or instructors to facilitate the training (Berenson et al, 2020 ; Biro et al, 2021 ; Block et al, 2020 ; Click et al, 2019 , 2020 ; Greene et al, 2017 ; Marshall et al, 2017 ; McCave et al, 2019 ; Park & Safer, 2018 ; Rosendale & Josephson, 2017 ; Sawning et al, 2017 ; Sequeira et al, 2012 ; Stumbar et al, 2021 ; Thompson et al, 2020 ; Ufomata et al, 2020 ; Vance et al, 2018 ) and availability of transgender simulation patients (Berenson et al, 2020 ; Biro et al, 2021 ; Block et al, 2020 ; Click et al, 2019 , 2020 ; Greene et al, 2017 ; Marshall et al, 2017 ; McCave et al, 2019 ; Park & Safer, 2018 ; Rosendale & Josephson, 2017 ; Sawning et al, 2017 ; Sequeira et al, 2012 ; Stumbar et al, 2021 ; Thompson et al, 2020 ; Ufomata et al, 2020 ; Vance et al, 2018 ). Low participation rates among certain subgroups (e.g., male and cisgender people) was the most reported barrier related to the audience (Braun et al, 2017 ; Minturn et al, 2021 ; Pathoulas et al, 2021 ).…”
