Assessing the impact of chemotherapy-induced nausea and vomiting on patients' daily lives: a modified version of the Functional Living Index?Emesis (FLIE) with 5-day recall

Background The Functional Living Index—Emesis (FLIE), a patient-reported outcome measure, was originally developed to assess the impact of chemotherapy-induced nausea and vomiting (CINV) on patients' daily lives over the 3 days following chemotherapy. More recent studies of CINV include assessments covering the 5 days following chemotherapy in an effort to capture information during both the acute (within 24 h) and delayed (up to 5–7 days) phases of CINV.
