China's Centralized Volume-Based Drug Procurement: Effectiveness and Lessons
摘要
Rising prescription drug costs are a significant global issue, with varied policy measures yielding mixed results in containing the costs. In this study, we analyze the impacts of the world’s largest centralized procurement initiative—China’s Centralized Volume-Based Drug Procurement (CVBP)—using unique, comprehensive data from all healthcare institutions in China. Using a staggered difference-in-differences design, we show that CVBP lowers prices of procured drugs by 67%, increases drug utilization by 7.6%, and reduces overall drug expenditure by 70%. The market share of winning (generic) drugs grows by 50%, while it decreases by 12.8% for branded drugs. We also observe a decrease in drug variety, primarily due to the exit of high-price drugs. Importantly, price reductions are driven not only by the initial drop of winning drugs but also by decreases among non-winning generics and branded drugs over time. For drug utilization, we examine trade-offs between price and quality. Specifically, unmet medical needs contribute to the increased quantities. Moreover, switch from branded to generics and the likely downgrade of winning generics due to manufacturing process change are also associated with an increase in drug utilization. Finally, supply reliability also helps to explain the varied responses across hospitals.
