Antiemetic use and chemotherapy induced nausea and vomiting related hospitalization costs after highly or moderately emetogenic chemotherapy.

Aim: Despite numerous available antiemetics, chemotherapy induced nausea and vomiting (CINV) still affects many patients, and CINV related hospitalizations and costs often result. Materials & methods: PrecisionQ analyzed its database to evaluate CINV related hospitalizations and costs following antiemetics use including netupitant/fosnetupitant with palonosetron (NEPA), aprepitant/fosaprepitant with ondansetron (APON) or aprepitant/fosaprepitant with palonosetron (APPA) in patients receiving highly emetogenic chemotherapy or moderately emetogenic chemotherapy. Results: Database analysis identified 15,583 patient records (807 NEPA, 2023 APON, 12,753 APPA) and mean CINV related hospitalization costs were lower across all patients receiving NEPA (US$301) compared with patients receiving APON ($1006, p < 0.0001) or APPA ($321, p < 0.0001). Conclusion: NEPA is associated with lower CINV related hospitalization costs compared with APON and APPA among patients receiving highly emetogenic chemotherapy or moderately emetogenic chemotherapy.
