[SUMMARY] This study aimed to determine the necessity of outpatient nurses introducing visiting nursing for older cancer patients undergoing outpatient chemotherapy, and to develop guidelines to support the process of considering the introduction of visiting nursing together with older cancer patients. In the 1st phase, guidelines (draft) were created based on qualitative content analysis of previous research and verbatim recordings obtained from individually conducted semi-structured interviews with 13 outpatient nurses and 10 visiting nurses. In the 2nd phase, a panel of six experts was held twice to gain consensus on the guidelines’ validity and feasibility. In the 3rd phase, a questionnaire was mailed to outpatient nurses employed at the 899 facilities throughout Japan that have certified nurses in cancer chemotherapy to confirm the importance and feasibility of each guideline item, and a final version of the guidelines was created. The guidelines consist of 30 primary and 129 secondary items on “patients subject to consideration of introducing visiting nursing,” “significance of introducing visiting nursing to older cancer patients,” “information on older cancer patients,” and “interaction aimed at introducing visiting nursing to older cancer patients” in the “period up to the first outpatient chemotherapy treatment,” “period of continued outpatient chemotherapy,” and “period when continuation of outpatient chemotherapy becomes difficult.” They included the perspective of ACP and are characterized by outpatient nurses focusing on the lives of the older cancer patients, continuing interaction while respecting their habits and values, and considering the introduction of visiting nursing together with the older cancer patients while eliciting their desired treatment and lifestyle. In addition, the utilization of these guidelines can be anticipated to promote cooperation between outpatient nurses and visiting nurses.
