From Research to Practice: Which Research Strategy Contributes More to Clinical Excellence? Comparing High-Volume versus High-Quality Biomedical Research

We collected secondary data on departments across three specializations (Cardiology, Oncology and Orthopedics) in 50 U.S.-based university hospitals served by 4,330 physicians. Data on volume and quality of biomedical research at each department was correlated with publicly available ratings of departments’ quality of care, demonstrating that high-quality research has significantly greater contribution to quality of care than high-volume research.

本研究收集了美国50家大学附属医院内三个专科（心脏病学（Cardiology）、肿瘤学（Oncology）、骨科学（Orthopedics））各科室的二手数据，这些医院共有4330名执业医师。我们将各科室的生物医学研究规模与质量数据，与公开可获取的科室医疗质量评级开展相关性分析，结果表明：相较于高规模的生物医学研究，高质量的生物医学研究对医疗质量的提升贡献更为显著。
