The partitioned survival model(PSM),utilized in pharmacoeconomics(PE)evaluation for decision-making models,is widely applied in PE evaluation of international oncology treatments due to its simplicity,intuitiveness,and direct data analysis from clinical literature,circumventing complex inter-state transition probability calculations.The R language,known for its efficiency,intuitive nature,and reproducibility of results,has been equipped with various specialized packages through years of application by researchers in Europe and America,significantly enhancing research productivity.However,there were few studies about the use of R language for PSM analysis of oncology drug treatments in China.This article aims to present a comprehensive operational procedure for PSM analysis of oncology drug treatments using R language,combined with practical cases,and to offer a reference for researchers in the field.
