Abstract: Objective: To comprehensively search, summarize, and analyze summaries of the best evidence for risk assessment of Chemotherapy-Induced Nausea and Vomiting. Methods: Computerized systematic searches of clinical decision websites, major guideline websites, professional association websites, evidence-based literature repositories, and major literature databases for clinical decisions, guidelines, expert consensus, evidence summaries, and systematic reviews on Chemotherapy-Induced Nausea and Vomiting and risk factor assessment in China and abroad were conducted, and methodological quality evaluations were performed and summarized to extract evidence with professional judgment and clinical context. Results: A total of 22 papers were included, including 5 clinical decisions, 8 guidelines, 4 expert consensus, and 5 systematic reviews. A total of 12 pieces of evidence were summarized from 5 directions: symptom assessment, risk factors, assessment timing, assessment tools and assessors. Conclusion: Evidence summaries provide an evidence-based basis for improving the accuracy of risk assessment for Chemotherapy-Induced Nausea and Vomiting, and healthcare providers should establish a Chemotherapy-Induced Nausea and Vomiting risk assessment form, assessment process, and practice standards. Healthcare professionals should apply the evidence in a rational manner, taking into account clinical situations and professional judgment, in order to accurately assess their associated risks.
