  Precision oncology tests that profile tumors to identify clinically
actionable targets have rapidly entered clinical practice. Effective visual
presentation of the results of these tests is crucial in accurate clinical
decision-making. In current practice, these results are typically delivered to
oncologists as static prints, who then incorporate them into their clinical
decision-making process. However, due to a lack of guidelines for
standardization, different vendors use different report formats. There is very
little known on the effectiveness of these report formats or the criteria
necessary to improve them. In this study, we have aimed to identify both the
tasks and the needs of oncologists from precision oncology report design and
then to improve the designs based on these findings. To this end, we report
results from multiple interviews and a survey study (n=32) conducted with
practicing oncologists. Based on these results, we compiled a set of design
criteria for precision oncology reports and developed a prototype report design
using these criteria, along with feedback from oncologists.
