Chemotherapy-related adverse outcomes, unexpected hospitalizations, and emergency department visits

In this study, chemotherapy-related adverse outcomes were evaluated within 3 months of treatment according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 [49] published by the National Cancer Institute (NCI). The CTCAE has five levels of severity, with a higher level indicating more severe side effects (toxicity) experienced by the patient. The study also collected data on whether patients had unexpected hospitalizations and emergency department visits within 3 months of treatment.
