Standards and quality assurance in interventional oncology: The establishment of the International Accreditation System for Interventional Oncology Services (IASIOS).

Quality assurance is integral to benchmarking and continuous improvement in the clinical care of people affected by cancer. Quality assurance systems are built upon agreed clinical and administrative standards. The Cardiovascular and Interventional Radiology Society of Europe (CIRSE) first developed a set of Standards for Interventional Oncology Services modelled on the Standards of Practice in Radiation Oncology developed in Australia and New Zealand. A subset of these Standards has been used to develop a tiered International Accreditation System in Interventional Oncology (IASIOS). This system covers the entirety of the patient care pathway from referral through to discharge and is clearly aimed at setting the benchmark for safe, quality interventional oncology (IO) services. Such a system has multiple benefits, including increasing the awareness of the availability of IO services and assurance in the quality of the care delivered to patients.
