ABSTRACT
BACKGROUND:
Clinical use of vascular
stents involves high medical
costs,but it may also bring long-term benefits in reducing cardiovascular events and improving the
quality of life in
patients.
Economics evaluation can help
decision makers better understand the balance between the
cost and benefit of
treatment.
OBJECTIVE:
To analyze the related articles of
health economics and discuss the hot spots in the study of the effect and problems of vascular
stents in medical
quality management.
METHODS:
The articles concerning
health economics evaluation of vascular
stents were retrieved from the core set of the Web of
Science.The VOSviewer_1.6.19
software was used to make a visualization
analysis of the annual
publication volume,institutions,countries,
keywords,etc.Finally,the
research hot spots on the effects and problems of vascular
stents were analyzed from the perspective of
health economics and medical
quality management. RESULTS AND
CONCLUSION:
(1)120 articles in English were finally included.In the past 10 years,the highest number of articles published in this field was in 2019,with 10 articles.The institution with the largest number of articles published was Harvard
University in the
United States with 20 articles,and the country with the largest number of articles published was the
United States with 58 articles.(2)
Keyword cluster analysis demonstrated that the
cost-effectiveness analysis of bare
metal stents and
drug-eluting stents in
coronary disease,the
cost-effectiveness analysis of
angioplasty stent intervention,and the effect of coronary
stents in
percutaneous coronary intervention are the
research hot spots in the field of
health economics evaluation of vascular
stent research.(3)In the context of medical
quality management,the
paper further summarized the
research hot spots on the
therapeutic effect of vascular
stents as follows
long-term effect of vascular
stents,
safety,
drug release mechanism
research,personalized
therapy,restenosis problems,and
stent insertion
technology.(4)The results of highly cited
literature analysis exhibited that
drug-eluting stents release
drugs to reduce the
risk of vascular restenosis,and the restenosis rate is lower than that of bare
metal stents,but the
cost is usually higher.Biodegradable
stents combine the advantages of bare
metal stents and
drug-eluting stents,that is,avoiding long-term
stent existence and reducing the
risk of restenosis,but their
cost may be higher,and there may be some
complications in the short term,and they are not widely used at present.(5)In addition to the direct
stent cost,factors that need to be considered when comparing the
cost-
effectiveness of vascular
stents include the
risk and
cost of
stent re-intervention,the
risk and
cost of
complications,the duration and
cost of
drug therapy,and the
quality of life of
patients.Therefore,while the initial
cost of
drug-eluting and biodegradable
stents may be higher than bare
metal stents,they may
lead to better clinical outcomes in the long term,resulting in a more favorable
cost effect.(6)
Future research directions should focus on making personalized vascular
stent treatment decisions,observing the
long-term effect of
stent treatment,the impact of the
stent on
patients'
quality of life,formulating
health policies,rational allocation of medical
resources,and the establishment of long-term follow-up mechanisms.
