Conclusion:

Despite the provided refresher’s courses and training, we observe a substantial underreporting of codes by RTT’s using the TLP. While TLP’s appear very useful, the results show that they can also provide a false sense of security. We are currently looking further into the reasons for underreporting. Based on the increased interpretation time for unreported code orange/red fractions, we may infer that RTTs in clinic often notice ITACs but more frequently sought online physician involvement without offline reporting. In addition, the lack of reporting capabilities on the online treatment screen may cause RTTs to perceive an obstacle to add an imaging code. It is important to mention that an unreported code orange does not necessarily indicate a deteriorated dose distribution. The limitation of this study is that only one IGRT specialist reviewed the images. Image interpretation generally remained under five minutes for the majority of fractions, indicating that there is the potential to interpret and especially report the images more thoroughly if needed during online image-registration. It is now essential to establish a robust communication system between RTTs and physicians to promote more frequent and accurate reporting of ITACs.
