Connecting minds and catalyzing collaboration: the interest groups of health technology assessment international.

Health Technology Assessment international (HTAi) supports global collaboration and innovation in HTA through its dynamic network of Interest Groups (IGs). These thematic communities provide a dedicated platform for members to engage in focused, collaborative efforts that drive professional exchange, advance methodologies, and develop best practices in HTA. This commentary offers a panoramic overview of all IGs, their evolution, aim, and initiatives. By drawing on diverse stakeholder perspectives, spanning academia, clinical practice, industry, and patient communities, the IGs foster inclusiveness and extend HTAi's influence to significantly contribute to the broader HTA community. Through activities such as workshops, conference sessions, webinars, publications, and research projects, they offer opportunities for professional development and thought leadership. The IGs' cross-cutting contributions position them as engines of innovation to ensure HTAi remains at the forefront of shaping a globally relevant, responsive, and ethically grounded HTA ecosystem.
