International Ototoxicity Management Group (IOMG)

Ototoxic logo The International Ototoxicity Management Working Group (IOMG) is a global consortium of international stakeholders from universities, task forces, health foundations, professional societies, government agencies and patients created to address healthcare gaps in the clinical management of individuals who experience hearing loss, tinnitus, and/or balance difficulties following medical, occupational or environmental exposures to ototoxicants. Ototoxicity management includes the diagnosis, monitoring, rehabilitation and/or therapeutic treatment of these cases. Despite the well-established physical, socio-economic, and psychological consequences of hearing and balance dysfunction, clinical practice in these situations is not consistent within or across countries. Few healthcare delivery models integrate ototoxicity management into the essential and/or life-preserving care pathways that utilize therapies that unavoidably increase the risk of ototoxicity. Additionally, there are no standard methods for the auditory surveillance of individuals exposed to hazardous chemicals at work. Consensus guidelines and tools for implementation and health promotion are needed to proactively manage ototoxicity from medical, environmental and occupational exposures. The IOMG will enhance the social participation and quality of life of millions of individuals worldwide by addressing healthcare gaps and promoting ototoxicity management that will give patients and workers greater control over their long-term auditory and vestibular health.

Our long-term goal is to develop a comprehensive set of guidelines and/or position statements, implementation and health promotion tool kits that will address ototoxicity management gaps in relation to best practices. Our approach is to harmonize consensus opinion from international experts with the priorities of patients and the specific organizations that govern have the power to influence patients’ ototoxic exposures. To reach this goal, near-term objectives are to establish best practices for widespread implementation of ototoxicity management in specific clinical environments (e.g., medical oncology, pulmonology, otology, audiology, cystic fibrosis and infectious disease clinics), healthcare structures (community-based, government, third party payer), and regional economies (emerging, transitional, strong). Guided by an international team of patients, clinicians, researchers, and policy makers the group plans to disseminate ototoxicity management materials and toolkits in traditional and non-traditional formats to accommodate specific work environments, healthcare structures, healthcare workers, and patients across the globe.
