Prior research has faulted the US News and World Report hospital specialty rankings for excessive reliance on reputation, a subjective measure of a hospital's performance.
To determine whether and to what extent reputation correlates with objective measures of research productivity among cancer hospitals.
A retrospective observational study.
Automated search of NIH Reporter, BioEntrez, BioMedline and Clinicaltrials.gov databases.
The 50 highest ranked cancer hospitals in 2013's US News and World Report Rankings.
We ascertained the number of NCI funded grants, and the cumulative funds received by each cancer center. Additionally, we identified the number of phase I, phase II, and phase III studies published and indexed in MEDLINE, and registered at clinicaltrials.gov. All counts were over the preceding 5 years. For published articles, we summed the impact factor of the journals in which they appeared. Trials were attributed to centers on the basis of the affiliation of the lead author or study principal investigator.
Correlation coefficients from simple and multiple linear regressions for measures of research productivity and a center's reputation.
All measures of research productivity demonstrated robust correlation with reputation (mean r-squared = 0.65, median r-squared = 0.68, minimum r-squared = .41, maximum r-squared = 0.80). A multivariable model showed that 93% of the variation in reputation is explained by objective measures.
Contrary to prior criticism, the majority of reputation, used in US News and World Rankings, can be explained by objective measures of research productivity among cancer hospitals.
先前的研究指责《美国新闻与世界报道》的医院专科排名过度依赖声誉，而声誉是对医院绩效的主观衡量。
确定癌症医院的声誉与研究生产力的客观指标之间是否存在关联以及关联程度如何。
一项回顾性观察研究。
对美国国立卫生研究院报告、生物Entrez、生物医学数据库和临床试验.gov数据库进行自动搜索。
2013年《美国新闻与世界报道》排名中位列前50的癌症医院。
我们确定了国立癌症研究所资助的拨款数量以及每个癌症中心收到的累计资金。此外，我们确定了在MEDLINE上发表并编入索引以及在临床试验.gov上注册的I期、II期和III期研究的数量。所有计数均基于过去5年的数据。对于已发表的文章，我们计算了它们发表所在期刊的影响因子总和。试验根据第一作者或研究主要研究者的所属机构归属于各个中心。
研究生产力指标与中心声誉之间的简单和多元线性回归的相关系数。
所有研究生产力指标均与声誉表现出强烈相关性（平均决定系数=0.65，中位数决定系数=0.68，最小决定系数=0.41，最大决定系数=0.80）。一个多变量模型显示，声誉变化的93%可由客观指标解释。
与先前的批评相反，《美国新闻与世界报道》排名中使用的大部分声誉可以通过癌症医院研究生产力的客观指标来解释。
