This Forum will highlight the ongoing activities to build diversity, equity and inclusion (DE&I) within ISPOR with an aspiration to have a well-represented HEOR workforce in the future. This initiative involves a cross-functional collaboration between ISPOR’s Institutional Council, Student Network, Regional Chapters, and Faculty Advisor Council to leverage resources and connections to scale-up DE&I initiatives. The session will begin with ISPOR’s commitment to understand diversity within its membership. Presentations will be followed on initiatives to help increase student, early professionals, and faculty awareness regarding the HEOR field and diverse mentoring opportunities for career guidance. ISPOR’s health equity research initiatives through a newly formed Special Interest Group (SIG) will also be spotlighted. The session will end with a call to action for members to replicate initiatives within their organization and a description of future areas of focus for ISPOR’s DE&I efforts.
