Increased consumption of cardiovascular drugs under volume-based procurement (VBP) policy: demand release or assessment inducing?
Article in Health research policy and systems, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundThe phenomenon of growth in drug consumption within the framework of national volume-based procurement (VBP) policy raises speculations about demand release and policy inducing. This study aims to explore the reasons and mechanisms of drug consumption increases following VBP policy from two perspectives.
methodsWe collected data from the China Drug Supply Information Platform, National Bureau of Statistics and the Joint Procurement Office. Twenty cardiovascular international non-proprietary names (INNs) in the first three VBP batches and 28 observation regions were included, constructing 418 valid INN-region combinations as the unit for analysis. The average monthly consumption volume of VBP cardiovascular drug was assigned as the explained variable. The generalized difference-in-difference method was conducted using the price reduction level and the size of policy assessment task as the policy intensity indicator. Moderating effect model was employed to examine the role of resident's income level.
resultsIncreased cardiovascular drug consumption was observed in 285 (68.18%) INN-region combinations after policy implementation. Under VBP policy, the price reduction level was significantly correlated with drug consumption in total (β = 0.144, p < 0.001), as well as in tertiary hospitals, secondary hospitals and primary healthcare centers (PHCs) (all p-values < 0.05). Resident's income level negatively moderated the impact of price reduction level on drug consumption in total (β = -0.089, p < 0.001) and in secondary hospitals (β = 0.154, p < 0.001) and PHCs (β = -0.2.9, p < 0.001), rather than in tertiary hospitals (β = -0.079, p > 0.05). The size of policy assessment task was positively associated with drug consumption in total (β = 0.052, p < 0.001), as well as in tertiary hospitals, secondary hospitals and PHCs (all p-values < 0.05).
conclusionsTwo mechanisms codrive drug consumption increases under VBP policy: first is the improvement of cardiovascular medication access and consumption toward lower-income groups following price reduction, pointing to the fulfillment of unmet needs, and second is policy pressure from supporting assessment measures on hospital drug use, indicating potential overprescribing.
