影像学中的企业赞助研究支付：美国Open Payments数据库全国性分析
该研究基于CMS Open Payments数据库2019至2024年数据，评估企业研究支付中流向放射科医生的比例趋势。结论指出放射科企业研究资助份额相对较小且比例下降，大部分资金流向非覆盖实体而非教学医院，性别差异持续存在。
要点
- 放射科企业研究资助份额仅1.1%且逐年下降，提示研究支持有限。
- 多数资金流向非覆盖实体而非教学医院，教学医院竞争力需加强。
- 放射科前20%的医生获得约80%的企业研究支付，集中度高。
核心结论
- 放射科企业研究资助份额相对较小（2024年1.1%）且比例随时间下降，提示研究支持有限。
- 大部分资金流向非覆盖实体而非教学医院，且性别差异持续存在。
- 专业学会和学术部门需制定策略提高放射科对企业赞助研究的竞争力，尤其在教学医院。
研究设计与样本
- 研究类型为基于CMS Open Payments数据库的全国性分析，数据年份为2019至2024年。
- 研究支付分为三类：直接支付给医生、覆盖接收方教学医院、非覆盖实体。
- 2024年支付分布按行业支付方、接收医生和接收非覆盖实体进行分析。
临床应用与阅片要点
- 了解企业研究资助在放射科的分布有助于学术部门制定科研筹资策略。
- 注意大部分资金流向非覆盖实体，教学医院需提升竞争力以吸引企业赞助。
- 放射科医生前20%获得约80%支付，提示资源集中，可能影响研究多样性。
局限性
- 研究为基于数据库的回顾性分析，可能存在数据录入不完整或分类偏差。
- 仅分析企业研究支付，未涵盖其他研究资助来源。
- 未报告样本量、中心数等详细信息，无法评估代表性。

INTRODUCTION: Industry funding for research is important in the era of decreasing federal research support. The goal of this study was to assess the trends in the proportion of industry research payments to radiologists.
METHODS: Research payment data from industry was gathered from the CMS Open Payments Database, for the years from 2019 to 2024. Overall industry payments in three categories were determined as well as proportion to radiologist principal investigators (PIs): (1) direct payments to physicians, (2) covered recipient teaching hospital, and (3) noncovered entities. The distribution of payments in 2024 was analyzed according to industry payors, recipient physicians, and recipient noncovered entities.
RESULTS: Of all research payments in 2024, 5,782 (0.76%) payments were made to radiologists, with a total value of $90.4 million (1.1% share of the total value). Noncovered recipient entities with 599 associated PIs received $64.2 million (1.0% of all specialties), covered recipient teaching hospitals with 257 PIs received $21.6 million (1.3% of all specialties), and 174 covered recipient radiologists received $4.6 million (4.9% of all specialties) in direct research payments. The top 20th percentile of radiologists (189 of 898) received roughly 80% of the total industry payments. Of all research payments, the proportion in radiology (radiology's share) decreased from 1.34% ($89.1 million of $6,641.7 million) in 2019 to 1.06% ($90.4 million of $8,515.6 million; P = .04) in 2024. In an exploratory analysis, only $1.04 million in artificial intelligence-specific research payments were made to radiologists (1.1% of all payments to radiologists).
CONCLUSIONS: Radiology's relatively small share of industry research funding (1.1% in 2024) with a declining proportional share over time suggests limited research support. The majority of funding flows through noncovered entities rather than teaching hospitals, and significant gender disparities persist. Professional societies and academic departments may need to develop strategies to increase radiology's competitiveness for industry-sponsored research, particularly at teaching hospitals.
