Oncologist perspectives on chemotherapy-induced nausea and vomiting (CINV) management and outcomes: A quantitative market research-based survey.

Abstract

BackgroundChemotherapy‐induced nausea and vomiting (CINV) is a distressing side effect that can negatively impact patients' quality of life and could discourage completion of chemotherapy, thereby affecting overall treatment outcomes. Although adherence to antiemetic guidelines can reduce CINV incidence in patients receiving highly or moderately emetogenic chemotherapy, CINV control remains inadequate.AimsThe objectives of this survey were to determine oncologists' practice patterns in CINV management, identify factors that contribute to antiemetic treatment failure, and determine the outcomes of uncontrolled CINV on health care resource utilisation and on patients' attitude towards chemotherapy.Methods and resultsQuantitative market research was performed using an online questionnaire. Responses from 300 European oncologists who prescribe antiemetics and see ≥50 patients/month were analysed. Results showed that the main reasons reported by oncologists for antiemetic treatment failure were underestimating the emetogenic potential of chemotherapy, utilising weaker antiemetic regimens than required, and patient non‐adherence because of administration mistakes or missed/delayed doses. Educational initiatives for the oncology multidisciplinary team may help improve guideline‐consistent prescribing. Also, the availability of simpler, more convenient antiemetic therapies may improve guideline adherence and patient compliance during home administration.ConclusionAchieving effective CINV control is a crucial goal to improve patients' quality of life, which should optimise chemotherapy outcomes, and would ultimately reduce health care costs.
