“I chose the field of oncology because I wanted to help those who are truly in need. Cancer used to mean no answer, but over time this theme has changed - the research and new medications that are now on the market have tremendously improved cancer care and survival rates. I will work hard for my patients and do my best to make cancer a chronic disease rather than a terminal illness.”

Nurses play a vital role at Saint Francis, and will be your first line of contact throughout your cancer treatment. Our knowledgeable, compassionate nurses are specially trained in oncology, and many possess advanced certifications in cancer treatment.

  • Nurse Practitioners (APRNs) and Physician Assistants (PAs) – Nurse practitioners and physician assistants have completed advanced levels of education in nursing. They begin seeing patients on the second or third visit after the doctor has developed the treatment plan, and continue to oversee the patient through survivorship. These nurses are the liaisons between the patients and doctors, keeping everyone updated on progress and care.
  • Clinic Nurses – Clinic nurses act as facilitators in many different ways. They are responsible for accessing new patient information from the front office and preparing it for the doctor prior to the first visit, and will continue to keep patient charts current and ready for the doctors, chemotherapy nurses and any outside medical offices that may need them. Clinic nurses are also responsible for communicating treatment plans to the chemotherapy nurses as well as developing survivorship care plans for patients who are finishing treatment.
  • Chemotherapy Nurses – Chemo nurses are responsible for the actual administration of chemotherapy to the patients. They will provide information and education to the patient on their specific treatment as well as create and explain their discharge plan. Chemotherapy nurses also work directly with the pharmacy and scheduling departments to double-check doses and days of treatment, and will communicate with outside facilities if a patient’s lab procedures take place outside of Saint Francis.
  • Triage Nurses – The triage nurse is the patient’s direct access to information, answering questions and providing referrals regarding chemotherapy side effects, pain control and the emotional concerns that arise from treatment. They communicate with the medical oncologists and rehab team to ensure patients’ needs are being met. In addition, triage nurses facilitate contact with outside pharmacies, labs and clinics, making sure prescriptions are filled and appointments are set.

Two triage nurses are available by phone during normal business hours. Any after-hours calls will be answered by a nurse practitioner, with a physician on-call for more advanced needs.
