| Summary: | The number of server failures, including those in radiotherapy, has dramatically increased over the past 5 years, primarily due to cyberattacks. Despite this trend, many clinics remain unprepared to handle such situations effectively. While it is possible to resolve these issues with thorough preparation and dedicated effort without causing significant interruptions to patient treatments, the process is considerably easier if numerous steps and analyses, both technical and clinical, have already been undertaken. This preemptive work allows for quicker responses and a faster resumption of patient treatments. There are established guidelines on how to prioritize patients and manage total dose in the event of multiple missed treatment sessions. However, many radiotherapy departments in Germany still lack individualized plans for handling software failures. In this article, we describe a failure of the radiotherapy OIS (ARIA by Varian) caused by an interface failure in the Central IT department of the clinic. From this event, we developed a clinical guideline for addressing issues during the outage and identified clinical processes that can be implemented in advance. Our focus was particularly on handling the large volumes of data involved in organizing patient treatments and scheduling. Overall, there needs to be a cultural shift in both the development of technical server infrastructures and the approach to managing OIS failures, as the likelihood of such events increases along with the negative impacts due to increasingly complex treatment plans and software landscapes. |
