Impact of volume-based procurement policy on coronary stent use in tianjin: interrupted time series analysis.
Article in Journal of health, population, and nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis 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.
methodsAn interrupted time-series design was used to assess monthly procurement data of coronary stents and balloons in Tianjin from January 2019 to December 2021.
resultsThe 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).
conclusionThe 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.
