Intended and Unintended Impacts of '4+7' Volume-Based Drug Procurement on the Use of Drugs in China: A Natural Experimental Study.

Background: Volume-based drug procurement is regarded as a pharmaceutical cost-containment measure in healthcare provision globally. The Centralized Volume-Based Drug Procurement (CVBDP) launched in March 2019 in China, also known as the '4+7' policy. 11 cities, including Xi'an city in Shaanxi Province, were set up as pilots. This study aims to examine the intended and unintended impacts of the '4+7' policy on the use of original and generic drugs in city-level and county-level hospitals in Shaanxi, China. Methods: The data used in this study came from the Shaanxi Drug and Apparatus Centralized Procurement Platform (SDACPP). In total, 111,999 drug procurement order records of 118 policy-related drugs (including 25 '4+7' policy-list drugs and 93 alternative drugs by generic name) from April 2017 to November 2019 were included in analyses. Policy-list drugs were divided into bid-winning and non-winning drug products. The volume and the expenditure of the drugs served as the outcome variables, measured by Defined Daily Doses (DDDs) and Chinese yuan (CNY), respectively. A difference-in-differences (DID) approach was used to estimate the policy's net effect. Results: After the '4+7' policy, the volume of bid-winning, policy-list, and policy-related drugs increased. An unexpected increase in volume was observed among alternative drugs, especially original drugs in city-level hospitals. The expenditure of policy-list and non-winning drugs declined, whereas that of alternative drugs unanticipatedly increased. Changes in volume and expenditure were both greater in generic drugs and in city-level hospitals, compared to their original and county-level hospital counterparts. Conclusions: Our findings highlight the positive effects of the '4+7' policy on generic drug substitution and pharmaceutical expenditure containment, which are greater in city-level hospitals. The unanticipatedly incremental volume of original drugs in city-level hospitals suggests the potential risk of the poor quality of bid-winning drugs, lower compliance with bid-winning drugs among patients, or physicians' profit-seeking behaviors in urban areas. More regulations and supervisions for the prescription and financial incentives of physicians are needed to address these concerns.

期刊介绍: Healthcare (ISSN 2227-9032) is an international, peer-reviewed, open access journal (free for readers), which publishes original theoretical and empirical work in the interdisciplinary area of all aspects of medicine and health care research. Healthcare publishes Original Research Articles, Reviews, Case Reports, Research Notes and Short Communications. We encourage researchers to publish their experimental and theoretical results in as much detail as possible. For theoretical papers, full details of proofs must be provided so that the results can be checked; for experimental papers, full experimental details must be provided so that the results can be reproduced. Additionally, electronic files or software regarding the full details of the calculations, experimental procedure, etc., can be deposited along with the publication as “Supplementary Material”.
