Recommendations from the Royal Australian and New Zealand College of Radiologists on imaging for ankle trauma, deep venous thrombosis (DVT), pulmonary embolism, low back pain, whole breast radiation therapy, prostate cancer, bone metastases, brain radiation therapy & locoregional therapy. RANZCR is a non-profit association that delivers skills, knowledge, and insight to promote the science and practice of the medical specialties of clinical radiology (diagnostic and interventional) and radiation oncology.

Don’t initiate whole-breast radiation therapy as a part of breast conservation therapy in women age ≥50y with early-stage invasive breast cancer without considering shorter treatment schedules.

Date reviewed: 1 October 2016

Whole-breast radiation therapy decreases local recurrence and improves survival of women with invasive breast cancer treated with breast conservation therapy. Most studies have utilised "conventionally fractionated" schedules that deliver therapy over 5-6 weeks, often followed by 1-2 weeks of boost therapy. Recent studies, however, have demonstrated equivalent tumor control and cosmetic outcome in specific patient populations with shorter courses of therapy (∼4 weeks). Patients and their physicians should review these options to determine the most appropriate course of therapy.

How this list was made How this list was made

Clinical radiology recommendations 1-6 (April 2015)

A team of five Lead Radiologists were nominated to guide RANZCR's Choosing Wisely contribution. These Lead Radiologists analysed previous work completed by RANZCR, in particular a series of Education Modules for Appropriate Imaging Referrals.

These modules had been developed from an extensive evidence base and with multiple stakeholder input. Using the evidence from the Education Modules, the Lead Radiologists developed a draft recommendations list, which was then further developed and endorsed by RANZCR's Quality and Safety Committee, before being circulated to the RANZCR membership for consultation with a request for alternative recommendations. Member feedback was reviewed by the Lead Radiologists prior to ratification of the final recommendations by the Faculty of Clinical Radiology Council. The final six items selected were those that were felt to meet the goals of Choosing Wisely, i.e. those which are frequently requested or which might expose patients to unnecessary radiation.

Due to the fundamental role of diagnostic imaging in supporting diagnosis across the healthcare system, RANZCR worked closely with other Colleges throughout the project via the Advisory Panel. Following identification of two common recommendations with the Australasian College for Emergency Medicine, it was agreed by both Colleges to present these items jointly.

Radiation oncology recommendations 7-12 (October 2016)

Recommendations relating to radiation oncology from the Choosing Wisely and Choosing Wisely Canada were circulated around the Faculty of Radiation Oncology Council to determine which recommendations were applicable to the Australian and New Zealand context. The selected recommendations were then put to the Quality Improvement Committee and the Economics and Workforce Committee, with each being asked to rank the recommendations.

The five highest ranked recommendations were then put to the radiation oncology membership for consultation prior to being formally approved by the Faculty of Radiation Oncology Council.

Recommendations 7-10 are adapted from the American Society for Radiation Oncology (ASTRO) 2013 and 2014 lists. Recommendation 11 is adapted from Choosing Wisely Canada’s Oncology list. Each organisation was approached for—and subsequently granted—approval to adapt these recommendations as part of the Choosing Wisely Australia campaign.
