This global accreditation scheme is operated by the Interventional Radiology Accreditation Service GmbH (IRAS) and provides a unique opportunity to gain recognition for the IO services offered. Apart from giving facilities the chance to showcase their achievements, it is also intended to establish the highest standards for patient care and to encourage good practice in IO.


IASIOS is based on the Standards of Quality Assurance in Interventional Oncology, a comprehensive quality assurance document developed by the Cardiovascular and Interventional Radiological Society of Europe (CIRSE). It looks at the whole process of patient care and treatment and what is required to deliver IO services at a highly effective level. By featuring clearly outlined requirements, it functions as a framework for the development and implementation of wider measures for safe and efficient IO practice. The document has recently received wide international endorsement through relevant regional and national medical societies.


IASIOS is a membership-based accreditation system that has been specifically developed for medical facilities operating in interventional oncology and aspiring for formal recognition either as part of an existing institution or as an independent entity. Regardless of their size and location, any facility that wishes to obtain accreditation of their IO service line will be able to apply once the system has been launched officially.


In Spring 2018, IASIOS launched its first round of accreditations for selected hospitals only. During the pilot phase of the project, all fine-tuning and adjustment actions will be finalised to bring forward a unique and far-reaching accreditation programme in the field of IO. The formal launch of IASIOS for all hospitals is planned for late 2020/2021.
