The quality improvement in prostate radiotherapy based on results from end-to-end national audits

Original language description

In the Czech Republic, independent audits are performed by the National Radiation Protection since 1996. End-to-end audits are included in the auditing system since 2013 for prostate treatment with the anthropomorphic phantom. The audits include dosimetry checks (measurement with ionisation chambers in PTV, OAR, and with gafchromic film) together with plan quality analysis. For all audits, the same anthropomorphic pelvic phantom was used with indicated PTV, rectum, and bladder; and audits were performed by the same auditing group with the same dosimetry equipment to avoid bias. Contours in the phantom were not included and were intended to be drawn by the audited centre based on drilled holes. The local staff should plan the treatment according to the local rules (including the fractionation scheme). All DVHs were recalculated to the normofractionation with LQ model so inter-comparison was possible. In total, 67 on-site audits performed in 2013 – 2019 were analysed in this study for the prostate site. Because there were repeated audits for some departments connected with the installations of new treatment units and with the introduction of new treatment techniques (mostly VMATs) to the clinical practice, it was possible to track the progress at some departments based on previous audits. The results were divided into two groups: the first with results obtained within the national study performed at all departments in 2013 (19 departments, 23 audits), the second with results obtained in 2014 – 2019 (19 departments, 44 audits). Presented at ESTRO Congress 2020 (online).
