Role of Adverse Events in Unscheduled Hospitalizations Among Patients With Solid Tumors Who Receive Medical Oncology Treatment

PURPOSE:The development of strategies to prevent or mitigate cancer treatment–related adverse events (AEs) is necessary to improve patient experience, safety, and cost containment. To develop a strategy to easily identify and mitigate AEs, we sought to understand the frequency and severity of those that resulted in hospitalizations.METHODS:We retrospectively characterized hospitalizations of ambulatory adult patients with solid tumor cancers within 30 days of chemotherapy administration using medical record data abstraction. Hospitalizations were categorized as caused by cancer symptoms, a noncancer medical condition, or a medical oncology treatment-related AE. Severity of the treatment-related AE hospitalization was rated using the National Patient Safety Agency risk assessment matrix scale.RESULTS:Between May and October 2016, 116 patients experienced 197 hospitalizations (per-patient mean, 1.7 AEs; range, 1 to 7 AEs). Sixty-six percent (n = 130) of hospitalizations were related to cancer symptoms, wher...
