To assess the quantity and impact of research publications among US acute care hospitals; to identify hospital characteristics associated with publication volumes; and to estimate the independent association of bibliometric indicators with Hospital Compare quality measures.

In cross-sectional studies using a 40% random sample of US Medicare-participating hospitals, we estimated associations of hospital characteristics with publication volumes and associations of hospital-linked bibliometric indicators with 19 Hospital Compare quality metrics.
DATA COLLECTION/EXTRACTION METHODS: Using standardized search strategies, we identified all publications attributed to authors from these institutions from January 1, 2015 to December 31, 2016 and their subsequent citations through July 2020.
Only 647 of 1604 study hospitals (40.3%) had ≥1 publication. Council of Teaching Hospitals and Health Systems (COTH) hospitals had significantly more publications (average 599 vs. 11 for non-COTH teaching and 0.6 for nonteaching hospitals), and their publications were cited more frequently (average 22.6/publication) than those from non-COTH teaching (18.2 citations) or nonteaching hospitals (12.8 citations). In multivariable regression, teaching intensity, hospital beds, New England or Pacific region, and not-for-profit or government ownership were significant predictors of higher publication volumes; the percentage of Medicaid admissions was inversely associated. In multivariable linear regression, hospital publications were associated with significantly lower risk-adjusted mortality rates for acute myocardial infarction (coefficient -0.52, p = 0.01), heart failure (coefficient -0.74, p = 0.004), pneumonia (coefficient -1.02, p = 0.001), chronic obstructive pulmonary disease (coefficient -0.48, p = 0.005), and coronary artery bypass surgery (coefficient -0.73, p < 0.0001); higher overall Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) ratings (coefficient 2.37, p = 0.04); and greater patient willingness to recommend (coefficient 3.38, p = 0.01).
A minority of US hospitals published in the biomedical literature. Publication quantity and impact indicators are independently associated with lower risk-adjusted mortality and higher HCAHPS scores.
评估美国急症护理医院的研究出版物数量和影响力；确定与出版物数量相关的医院特征；并估计文献计量指标与医院比较质量指标的独立关联。

在使用美国医疗保险参与医院 40%随机样本的横断面研究中，我们估计了医院特征与出版物数量的关联，以及与医院相关的文献计量指标与 19 项医院比较质量指标的关联。
数据收集/提取方法：使用标准化搜索策略，我们从这些机构的作者那里确定了 2015 年 1 月 1 日至 2016 年 12 月 31 日期间发表的所有出版物及其随后在 2020 年 7 月之前的引用。
只有 1604 家研究医院中的 647 家（40.3%）发表了至少 1 篇论文。教学医院理事会和健康系统（COTH）医院的出版物明显更多（平均 599 篇，而非 COTH 教学医院为 11 篇，非教学医院为 0.6 篇），其出版物的引用频率也更高（平均每篇出版物 22.6 次引用）比非 COTH 教学（18.2 次引用）或非教学医院（12.8 次引用）。在多变量回归中，教学强度、医院床位、新英格兰或太平洋地区、非营利或政府所有是出版物数量较高的显著预测因素；医疗补助入院率呈负相关。在多变量线性回归中，医院出版物与急性心肌梗死（系数 -0.52，p=0.01）、心力衰竭（系数 -0.74，p=0.004）、肺炎（系数 -1.02，p=0.001）、慢性阻塞性肺疾病（系数 -0.48，p=0.005）和冠状动脉旁路手术（系数 -0.73，p<0.0001）的风险调整后死亡率显著降低相关；整体医院消费者评估医疗保健提供者和系统（HCAHPS）评分（系数 2.37，p=0.04）更高；以及患者更愿意推荐（系数 3.38，p=0.01）。
少数美国医院在生物医学文献中发表了文章。出版物数量和影响指标与较低的风险调整后死亡率和较高的 HCAHPS 评分独立相关。
