Imaging Services Accreditation Scheme (ISAS)

The Imaging Services Accreditation Scheme (ISAS)

The Royal College of Radiologists and the College of Radiographers have developed the Imaging Services Accreditation Scheme (ISAS) to support diagnostic imaging services to manage the quality of their services and make continous improvements; ensuring that their patients consistently receive high-quality services delivered by competent staff working in safe environments.

ISAS is jointly owned by the RCR and the Society and College of Radiographers (SCoR), who have developed the standard in consultation with imaging services across the country.

Accreditation to professional standards is supported by the Care Quality Commission (CQC), NHS England, NHS Northern Ireland and NHS Wales.

The United Kingdom Accreditation Service (UKAS) deliver and manage ISAS on behalf of the Colleges and carry out assesments for accreditation against all elements of the ISAS standard.
UKAS accreditation gives formal third-party recognition that an imaging services provider has demonstrated their organisational competence to deliver high quality imaging services.
Visit the ISAS website to find out more, including information about organisations accredited so far, workshops to help services prepare for ISAS accreditation, and becoming an ISAS assessor.

The Standard 2017
The new ISAS standard was released January 2017.
The, v2.1 2013 standard will still be used for those about to complete accreditation.
For those services that have been assessed against v2.1 2013, your UKAS assessment manager will be in contact to discuss and support your transition to v3. 2017, details can be found in the transition brochure

The new Standard now has five domains, 29 standard statements and 143 criteria compared with the previous version which had four domains, 33 standard statements and 213 criteria.
The Gap Analysis Tool (Traffic Light Ready, TLR) has also been extensively updated by UKAS.

Currently 33 services across the country have received accreditation and they are all are happy to answer questions you may have about their experience and you are welcome to visit their sites.

The College, in collaboration with SCoR, is delivering a series of webinars on the accreditation process. Two of these webinars are now available to view, ISAS 1 'Real Life Experience' and ISAS 2 'What makes good evidence?'. For information on the rest of the series visit webinars overview.
