1 IAEA Quality Audits in Radiotherapy Izewska, J; Bera, P; Azangwe, G*; Rosenblatt, E; Zubizarreta, E; Meghzifene, AInternational Atomic Energy Agency, Vienna, Austria
2 IAEA audits in radiotherapy SINCE 1969: IAEA/WHO TLD postal dose audits of radiotherapy beam calibration (>40 years of operation):126 countries, ~1850 hospitals, >9000 beamsSINCE 1981:TLD audits for ~70 SSDLsSINCE 2005:Quality AssuranceTeam for RadiationOncology (QUATRO)NEW: TPS audit
3 Dose audit networks for radiotherapy Country participating in the IAEA/WHO TLD serviceNational QA network or participant in international network other than IAEAQA network co-operating with IAEACountry not having radiotherapy or not participating in an audit network
10 On-site audit procedures Typically 5 days per RT departmentEntrance briefingAssessment: complete tour of facility, staff interviews, review & evaluation of procedures and documentation, measurements, tests of procedures, observation of practical workExit briefing: feedbackto the department,preliminaryrecommendations,questions, discussion.
11 QUATRO audits: summary Regional workshops have been organised to train auditorsSo far more than 70 missions have been conducted and more are plannedMost audits have been in EuropeQUATRO Audit assessed adequacies in:InfrastructurePatient related proceduresEquipment related proceduresTraining programmesStaffing
12 Recommendations by QUATRO Support staff continuous educationStrengthen QA programmes and proceduresEquipment: get more, use betterIncrease staffing level: MP, RO, RTTBetter trained staff: RTT, RO, MPImprove treatment protocolsImprove structure and organization of cancer centres
13 New IAEA procedures: TPS audit Set of practical tests for dosimetry calculations reflecting typical treatment techniques in a radiotherapy department
14 Implementation of TPS audit Steps in implementation of TPS audits:IAEA multicentre pilot studyTPS test audit runs in Baltic countries and HungaryNational TPS audit exercises supported by IAEA (Europe)TPS audit package is available from IAEA on request.
15 RESULT: QUALITY IMPROVEMENT – SAFETY FOR PATIENTS ConclusionThe IAEA/WHO TLD audits contribute to the improvement of the status of radiotherapy dosimetry worldwideQUATRO is a useful tool for peer reviewing radiotherapy practices; it documents weak links in hospital operations and procedures, and offers recommendations to address them.TPS audits help the physicist appreciate limitations of treatment planning systems and the importance of independent verification of plans before treatment.RESULT: QUALITY IMPROVEMENT – SAFETY FOR PATIENTS
