Impact of oncology pharmacy services on the management of chemotherapy-induced nausea and vomiting: A systematic review and meta-analysis.

This article systematically reviews and meta-analyzes the impact of clinical pharmacy services on managing chemotherapy-induced nausea and vomiting (CINV) in cancer patients. The findings indicate that pharmacist-led interventions significantly reduce the incidence of nausea and vomiting, particularly during the delayed phase (2 to 5 days post-chemotherapy), and improve secondary outcomes such as medication adherence, patient satisfaction, quality of life, emergency department visits, hospitalizations, and healthcare costs. The interventions typically include patient counseling, identification and management of medication-related problems, and supportive care tailored to individual needs. Despite heterogeneity among studies and a predominance of quasi-experimental designs, the evidence supports the valuable role of oncology pharmacists in enhancing CINV control and overall treatment experiences. The authors recommend further randomized controlled trials with standardized pharmacist services to strengthen these findings.
