Incidence and duration of chemotherapy-induced nausea and vomiting in the outpatient oncology population.
Abstract
Nausea and vomiting are commonly recognized side effects of chemotherapy. However, the incidence and duration of these effects have not been systematically studied in a large outpatient oncology population. This survey was conducted over two consecutive 6-week periods in the adult oncology clinics of two university teaching hospitals. The objectives were: (1) to document the incidence and duration of chemotherapy-induced nausea and vomiting; (2) to identify variables that influence nausea and vomiting; and (3) to describe patterns of antiemetic prescribing and compliance. One hundred thirty-eight completed patient-maintained diaries were returned (70% response rate). Anticipatory nausea and vomiting were reported by 9.4% and 6.5% of patients, respectively. Fifty percent and 27% of patients reported nausea and vomiting, respectively, on the day chemotherapy was administered (day 1: acute nausea and vomiting phase). Percentages fell to 22% and 11% by day three and 14% and 2.5% on day 5. Of patients who reported nausea and vomiting during the five-day period, 52% and 33% experienced nausea and vomiting, respectively, during the delayed period only (days 2 through 5: delayed emesis phase). Emetogenicity of chemotherapy significantly influenced incidence and duration of those symptoms. Sixty-seven percent of patients reported taking antiemetics on one or more days during the survey period. Of patients who reported antiemetic use, 92% reported antiemetics on day 1, 51% on day 3, and 31% on day 5. At-home antiemetic use was related to the emetogenicity of chemotherapy received. Patients who receive moderate to strong emetogens as defined in this report should receive antiemetic therapy for a minimum of three days. Increasing the dose of antiemetic prescribed both in the clinic and at home may be of benefit.
