Certified nurse specialists in cancer nursing and prophylactic antiemetic prescription for chemotherapy patients.

PURPOSE: The prevention of chemotherapy-induced nausea and vomiting (CINV), a common chemotherapy side effect, should be attempted by oncology nurses. Certified nurses could be certified nurse specialists in cancer nursing (CNSCNs), who have high-level graduate education, or certified nurses in cancer chemotherapy nursing (CNCCNs), who have short-term training. The relationship between these certifications and compliance with the CINV prevention guidelines has not been investigated. We aimed to evaluate the association between certified nurse staffing and prescription of prophylactic antiemetic drugs for chemotherapy patients with high emetic risk.

METHODS

We used health service utilisation data for cancer patients diagnosed in 2016 from 474 hospitals nationwide in Japan and a list of certified nurses published by the Japanese Nurse Association. Patients receiving highly emetic chemotherapy were included. A multilevel mixed-effect logistic regression analysis was conducted to estimate the prescription of prophylactic antiemetic drugs associated with CNSCN and/or CNCCN staffing.

RESULTS

Data of 46,306 patients were analysed. Overall, 68.4% and 94.0% of the patients received chemotherapy at hospitals with CNSCNs and CNCCNs, respectively. Small cell lung cancer, non-small cell lung cancer, breast cancer, and oesophageal cancer were positively associated with the prescription of recommended antiemetic drugs. CNSCNs was significantly associated with the prescription of prophylactic antiemetic drugs, while CNCCNs was positively but non-significantly associated with antiemetic prescriptions.

CONCLUSION

This study is the first to demonstrate that CNSCN placement was significantly associated with prescribing antiemetic drugs recommended by clinical guidelines. Patients are likely to receive appropriate supportive care with the proper placement of CNSCNs.
