[Cross-Functional Project of Using Information-Sharing Tool for Metastatic Colorectal Cancer Patients in University Hospital].

Treatment for late-stage cancer patients should be discussed depending on the patients' will, however it is not sometimes fully discussed in our daily practice. Based on this background, the information-sharing tool for metastatic colorectal cancer patients, who are refractory to first-line and second-line chemotherapy and/or who are given a year to live, has been introduced in our university hospital since November 2019. To evaluate the utility of this tool, the influence of the tools on the outcome of the patients was evaluated. Regarding the comparison between the patients before and after the introduction of the information-sharing tool, the period between the day of the consent to the DNAR between the day of the death is longer in the patients after the introduction than those before the introduction(median 43 vs 6 days, p=0.025). The introduction of the information-sharing tool can provide the metastatic colorectal cancer patients with more opportunities to discuss how to spend the rest of their lives and with longer time at the place where they want to stay.
