Conclusion The precise trade-off between the PB, bladder, and rectum dose depends on the patient’s anatomy, however, all patients showed a similar convex Pareto front. Based on a comprehensive Pareto front analysis, we conclude that it is possible to decrease the PB mean dose with 1-4Gy without increasing the dose to other OARs with a clinically relevant amount (>1Gy). Therefore, we recommend to implement BMS for the treatment of LACC patients with VMAT.

Patient pathways are complex in radiation therapy and detailed quality assurance and incident learning systems (ILS) are used to mitigate risk. However, errors still occur. This study aimed to benchmark the knowledge and understanding of SC and ILS in radiation oncology in Australia and New Zealand (ANZ). It was prompted by the gap in the literature on these topics for ANZ, with the majority of publications coming from authors in North America or Europe. Materials and Methods The Hospital Survey on Patient Safety Culture (1) was electronically distributed to radiation oncology professionals in ANZ during 2020; additional ILS-focused supporting questions were included. Participation was anonymous, with profession and location demographics collected. Results Approximately 5-10% of the radiation oncology workforce in ANZ responded, with 220 responses analysed. Overall positive safety culture (SC) was indicated for all ten areas explored, with teamwork showing the highest rating at 83.7%, followed by local management support (83.3%) and event reporting (77.1%). The three weakest areas differed from other studies reported in the literature and were communication about errors (63.9%), hospital-level management support (60.5%) and handovers and information exchange at interfaces (58.0%). The results showed different perceptions in the three primary cohorts: Radiation Oncologists (ROs), Radiation Therapists (RTs) and Radiation Oncology Medical Physicists (ROMPs). The RO and ROMP cohorts perceived some SC areas as negative (SC scores <50%). ROs perceived seven of the 10 SC areas as strong, >75%, with one needing improvement (between 50-75%) and two as negative. RTs perceived three strong, with the other seven needing improvement; ROMPs perceived eight needing improvement and two as negative. Most respondents utilised one or more ILS, with 59% perceiving one or more barriers to reporting. Variations in ILS utilisation and definitions were noted. Conclusion The findings established benchmark perspectives of SC and ILS in ANZ. These can be used when departments investigate their own departmental SC as a comparator. Differences in what and when to report suggest that more unified definitions at state, federal or bi-national levels are required and indicate a shared ILS specific to radiation oncology may eliminate multiple reporting systems and reduce barriers to reporting. The areas that showed weaknesses in SC highlight areas for further investigation. Further research into the different perceptions of SC by cohort is recommended. 1. AHRQ.
