Additional Study Information: This randomized clinical trial studies prophylactic colony stimulating factor management in patients with breast, colorectal or non-small cell lung cancer receiving chemotherapy and with risk of developing febrile neutropenia. Patients receiving chemotherapy may develop febrile neutropenia. Febrile neutropenia is a condition that involves fever and a low number of neutrophils (a type of white blood cell) in the blood. Febrile neutropenia increases the risk of infection. Colony stimulating factors are medications sometimes given to patients receiving chemotherapy to prevent febrile neutropenia. Colony stimulating factors are given to patients based on guidelines. Some clinics have an automated system that helps doctors decide when to prescribe them when there is a high risk of developing febrile neutropenia. Gathering information about the use of an automated system to prescribe prophylactic colony stimulating factor may help doctors use colony stimulating factor when it is needed.
