Abstract
Objectives
This study aimed to analyze the impact of China’s centralized volume-based procurement policy on the procurement and utilization of coronary stents in Tianjin from 2019 to 2021.
Methods
An interrupted time-series design was used to assess monthly procurement data of coronary stents and balloons in Tianjin from January 2019 to December 2021.
Results
The volume-based procurement policy significantly reduced coronary stents prices, with an average price reduction of 92.67% for ten selected stents, and the lowest price dropped to 469 CNY. Following policy implementation, annual procurement in Tianjin increased by 59.55%, and tertiary hospitals demonstrated a significant monthly level increase of 1,473.53 units (p = 0.027; 95% CI: 181.69–2,765.36). Imported stents procurement showed a significant level increase of 703.85 units (p < 0.0001), while domestic stents exhibited no significant monthly variation (p = 0.154). Structural upgrades accelerated: stainless steel stents decreased by 30.94% in usage share (p < 0.001; 95% CI: 17.36–44.52) and were rapidly phased out post-policy, whereas permanent-coated stents increased by 23.00% (p < 0.001; 95% CI: 18.46–27.54). Procurement expenditure decreased by 73.03% compared to the 2019 baseline. Drug-eluting balloons as an alternative technology remained unaffected (p = 0.32).
Conclusion
The study shows that Tianjin’s centralized volume-based procurement policy for coronary stents significantly improved stent supply and clinical utilization quality, while substantially reducing medical insurance expenditures—indicating that such policies can optimize healthcare resource allocation and enhance the cost-effectiveness of medical device procurement.
