International Accreditation System for Interventional Oncology Services

What to Expect


After getting authorisation from your administration or head of department, fill out the online registration form. You will be asked to appoint an authorised representative who will have formal responsibility for the application and the accuracy of the information provided and a designated contact person who will maintain correspondence with the IASIOS team. Following your registration, you will receive a confirmation email that includes a facility code that can be used to connect multiple users to the same online application.

After you have registered, the IASIOS office will contact you with an invoice for the enrolment fee and annual administration fee (if applicable). Once payment has been processed, you will be granted the status of IASIOS Enrolled Centre, and will receive the respective logos as well as access to the online IASIOS application and internal case review through your myIASIOS login.


We recommend having several members from your hospital working on the application together, and that you consult with your facility’s Quality Assurance department. In our experience, they have been a valuable resource to the centres that have achieved accreditation.

Please start with reading through the Standards of Quality Assurance document and familiarising yourself with the requirements. Please note that IASIOS splits the requirements and supporting evidence in the Standards of QA into “core criteria” and “extended criteria”. In the online application you will see which questions are core criteria and therefore required in order to receive accreditation. You will also be required to do an internal case review on 30 randomly selected patient files in order to complete the application.

It is not necessary to provide all the supporting evidence documents when you submit your application form, but please have them ready for submission if the assessors request supplemental information. Facilities may request additional consultation at any stage in the application cycle for an additional fee as stipulated in the Terms and Conditions.

Please note that there is no deadline for the submission of the application, and that the IASIOS team is available to consult you on technical and administrative issues along the way.


After your application and internal case review have been submitted, they will be reviewed by two independent assessors. In the case that during the evaluation process the assessors find the descriptions and supporting evidence unclear or ambiguous, they will request additional clarification or documentation from the facility. If the responses from the facility are still not enough for the assessors to accept the criteria as being met, a remote audit in the form of a teleconference will be scheduled. In rare cases, if the remote audit was unsatisfactory, a corrective action plan (CAP) is required from the facility with a description of the criteria that have not been met and what improvements will be implemented in order to correct them and possibly an on-site audit. The centre remains an IASIOS Enrolled Centre until a satisfactory assessment is achieved.

Once the process has been concluded, you will receive a letter from the IASIOS team informing you of the results of the evaluation, your IASIOS Accredited Centre seals and your framed IASIOS Accredited Centre Certificate.

If you have any questions about the accreditation process, please don’t hesitate to get in touch with the IASIOS team!
