Lesbian, gay, bisexual, transgender or non-binary and intersex (LGBTI) populations experience persistent health inequities, including poorer mental and physical health outcomes and higher unmet healthcare needs compared with non-LGBTI populations. These inequities are partly attributable to insufficient training of primary care physicians (PCPs) in LGBTI health. However, evidence on effective and scalable training interventions for PCPs remains limited, particularly outside North America. This study evaluates the effectiveness of a self-directed e-learning programme—Improving Care and Access for Rainbow Equity (I-CARE)—designed to improve PCPs’ knowledge, attitudes, skills and behaviours related to LGBTI health.
Methods and analysis
We will conduct a type I effectiveness-implementation hybrid, two-arm, parallel-group, superiority randomised controlled trial among PCPs practising in French-speaking Switzerland. Eligible physicians will be randomly assigned (1:1) to either the I-CARE programme (intervention) or an e-learning programme on motivational interviewing (control) matched for format and duration. Outcomes will be measured at baseline, immediately postintervention and at the 3-month follow-up. The primary outcomes are knowledge and attitudes towards LGBTI patients assessed at the postintervention time point using validated scales. Superiority will be declared if the intervention group is statistically significantly superior to the control group on at least one primary outcome and statistically significantly inferior on neither primary outcome. Secondary outcomes include skills, self-reported behaviours and the presence of LGBTI-inclusive environmental cues. Effectiveness will be analysed using generalised estimating equations. Implementation outcomes will be evaluated using the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework.
Ethics and dissemination
Participants will provide electronic informed consent. All study data will be managed and stored on secure servers hosted by the Lausanne University Hospital (CHUV). All information will be handled in strict accordance with the Swiss Federal Act on Data Protection. The project was approved by the Central Ethics Commission of the University of Lausanne on 7 July 2025 (C_Services centraux_052025_00018). Study findings will be disseminated through peer-reviewed scientific publications and lay summaries intended for the public, Swiss PCPs and LGBTI communities.
