[Cooperation between Clinics and Hospitals Using a Critical Path for G-CSF Prophylaxis in Cancer Chemotherapy]

Prophylactic granulocyte-colony stimulating factor(G-CSF)is necessary for some cancer patients receiving anti-cancer drugs. However, it is difficult for cancer patients in rural areas to receive G-CSF as outpatients because of inconvenient official transport, lack of public support, and low activity levels due to age. To resolve this problem, we began conducting a critical path(G-path)with regional medical institutions from 2011.

We retrospectively surveyed the clinical records of cancer patients receiving prophylactic G-CSF using G-path at our hospital.

Eighty-two patients who were administered a total of 254 cycles of chemotherapy were examined between January 2011 and December 2016. Diseases included malignant lymphoma(n=64), pancreatic cancer(n=7), soft tissue sarcoma(n=5), and others(n=6). The median age of the patients was 70(range: 24-94)years. Fifty-three patients visited medical offices, and 31 patients visited regional hospitals. In 245 of 254(96%)cycles, planned G-CSF administration was performed. In 37 of 254(15%)cycles, infectious episodes developed, but patients needed hospitalization for only 5 cycles(2%).

Cooperation between clinics and hospitals using G-path reduced ambulatory burden and prevented severe infection. Cooperation in supportive care may allow for equal accessibility to cancer treatment.
