Aims/objectives: This study was conducted to assess the utilization patterns of anticancer agents in patients with breast cancer and to provide practice recommendations/educational interventions to optimize medication use in patients with breast cancer.
Materials and methods: This was an ambispective study conducted for a period of 3 years at a private, specialty oncology care hospital in South India. In the initial phase, the selection of anticancer agents, dosage of anticancer agents, and management of chemotherapy-induced nausea and vomiting (CINV) were reviewed retrospectively (using paper medical records) with respect to the National Cancer Comprehensive Network guidelines. The administration of anticancer agents and anti-emetics were reviewed with respect to the hospital drug administration policies. The deviations from the standards were reported, and practice recommendations/educational interventions were developed. Treatment patterns were reevaluated prospectively after providing educational interventions. Descriptive statistics were used to report and compare the results from both phases.
Results: During retrospective phase, we observed 80% compliance in the selection of anticancer drugs, 74% compliance in drug dosing, and 63.5% compliance in the administration of anti-cancer agents. After the implementation of educational interventions, we observed 85% compliance in the selection of anticancer agents, 82.3% in their dosing, and 86.9% compliance in the administration of anticancer agents. For the management of CINV, we observed 75% compliance in the selection of drugs (vs. 53% during preintervention), 92% compliance in their dosing (vs. 90% during preintervention), 85.1% compliance in the administration of anti-emetics (vs. 50% during preintervention), and 80% compliance in the management of delayed CINV (vs. 60% during preintervention).
Conclusions: Treatment patterns of breast cancer were improved with respect to treatment standards after educational interventions to oncology care team.
