Joint Position Statement by the IAEA and WHO
Criteria for choice of investigationsInvestigations are recommended according to the following criteria:1. Clinical effectiveness
(evidence-based diagnostic/therapeutic impact)
2. Effective dose (effective low or no dose investigations preferred)
3. Cost-effectiveness (cheaper equally effective investigation preferred)
Essential for uniformity of practice

The Basic Safety Standards and “Justification”
Appropriate Imaging
• “The best test first”• Investigation should answer the clinical question
posed• Must be a justified investigation: benefit>>risk• Recommendations should give latitude for
equipment and expertise• Appropriate imaging should take into account
over-utilisation of imaging in some member states but under-utilisation of imaging in others
• Cost savings come from avoidance of unhelpful investigations
Justification and clinician involvement: IssuesOverloaded knowledge base
Medical and technical advancesCompetition for inclusion in curricula/CPD
Time challengedFastest test with shortest wait best?
Mixed messagesDifferent guidance from different sources?
Patient expectationsHistorical or geographical biasUnreliable evidence base from the web
Justification and clinician involvement : challengesDissemination of Referral Guidelines
Widely and freely available to end-users “If they haven’t heard it you haven’t said it” McLuhan
Implementation of guidance decision support tools?
“We shape our tools and thereafter our tools shape us” McLuhan
Uptakeneed buy-in by users and preferably ownership
“Computers can do better than ever what needn’t be done at all. Making sense is still a human monopoly” McLuhan
Monitoringclinical audit, feedback and education
“We drive into the future using only our rearview mirror ” McLuhan
Justification and clinician involvement: possible solutionsEducation Undergraduate and Continuing

African Regional Workshop on Imaging Referral Guidelines: Overview
Day 1 Setting the scene- why do we need referral guidelines, what are they, who should use them, what improvements may we get?
Day 2 Current status- what measures are in place in African countries; what good practices can be shared
Day 3 Strategies for improvement- existing, wanted and needed. Visit to the National PACS.
Day 4 The way forward- recommendations for national and international help
Break out Groups, Day 2 and Day 3
• To enable all participants to share experiences and good practices
• 2 streams, one in the French language, one in English
• Chairman and Rapporteur for each group• Chair will lead structured discussion• Rapporteur will feedback to all participants and
provide a framework for recommendations
Group 1: Barriers and solutions to appropriate imaging
Group 2: Strategies and tools for adopting/adapting, implementing, using and monitoring Imaging Referring Guidelines
African Regional Workshop on Imaging Referral Guidelines: Objectives
1. Understand benefits of imaging referral guidelines 2. Guideline implementation: Adopting and adapting
for appropriate imaging3. Introduction to methods for monitoring / audit of
appropriate imagingSecondary objectives are: a. To strengthen justification in diagnostic imaging;b. Reduction in unnecessary radiation dose to
patients.c. To promote awareness among referrers,
radiologists, radiographer and regulators. Clinical champions.
d. To address country-specific problems.Awareness, Appropriateness and Audit
Referrers, Radiologists, Radiographer and Regulators
