medication, hospitalisation and ambulatory visits) were also increased by CINV events. 4 Increased knowledge of the mechanisms underlying the manifestations of nausea and vomiting as a result of administration of cytostatic agents to oncology patients has undoubtedly greatly contributed to the development of improved drugs to prevent emesis. Although fairly effective in acute CINV, these agents are less than ideal in the control of delayed CINV, which acts through distinct biochemical and neurological processes. Therefore, management strategies based on more than purely mechanistic aspects that take into consideration individual variations in the development of CINV are strongly needed in the field. 1 Identification of risk factors The main risk factors identified in the literature as predictors of acute and delayed CINV regardless of prior use of chemotherapy include patient characteristics, such as young age and history of morning sickness, pre-chemotherapy stress and anxiety levels, emesis in TABLE 1 Important risk factors for development of CINV identified in the literature Patient-related risk factors • Age <55 years • Female gender • History of nausea and vomiting • History of morning sickness (pregnant women) • Occurrence of nausea and vomiting after prior cycles of chemotherapy • Symptom distress (pain) • High anxiety before the chemotherapy session • Less sleep during the night prior to the chemotherapy session • Use of non-prescription antiemetic drugs at home • Low alcohol consumption 28 | 2019 | hospitalpharmacyeurope.com Treatment-related risk factors • Use of anthracycline/ cyclophosphamide-based regimens (highly emetogenic) • Use of platinum-based regimens (highly emetogenic) • Initial cycles of chemotherapy • Adherence to antiemetic therapy
