While several recent studies suggest that approximately 1 in 6 young people in Switzerland are part of the rainbow diversity, a high proportion of health professionals have never had a course on LGBTIQ+ (lesbian, gay, bisexual, transgender, intersex, queer, questioning or other) health. This situation leads to significant gaps in the medical care of LGBTIQ+ persons as well as difficulties in accessing equitable, culturally appropriate and quality care. This article presents the ambitious and novel e-learning project I-CARE (Improving Care and Access for Rainbow Equity) which should contribute, from the end of this year, to filling the current gaps in the undergraduate and continuing education of health professionals.
