To establish whether there is an association between academic output and mortality rates for National Health Service (NHS) trusts.
Hospital standardized mortality ratios were obtained from Dr Foster hospital report cards. The Medline database of biomedical citations was queried to establish the number of citations credited to each NHS trust and constituent hospitals from 2006 to 2010. Admissions totals for NHS trusts for 2009-2010 were obtained from Hospital Episode Statistics Online. The number of citations per admission was calculated and used as an indicator of academic output as this reflects the workload of the trust.
Spearman's rank analysis was performed to identify any correlation between citations per admission and the inverse of four types of mortality rate: high-risk conditions, r = 0.20 (P = 0.01); low-risk conditions, r = -0.06 (P = 0.46); deaths after surgery, r = 0.193 (P = 0.019); and overall mortality, r = 0.291 (P < 0.01).
The results of this preliminary study demonstrate a significant correlation between academic output and mortality rates. The correlation coefficients are small, but the findings of this study encourage further debate.
确定学术产出与国民保健服务（NHS）信托机构的死亡率之间是否存在关联。
从福斯特博士医院报告卡中获取医院标准化死亡率比。利用生物医学引文的 Medline 数据库，从 2006 年到 2010 年，确定每个 NHS 信托机构和组成医院的引文数量。从医院入院统计在线获取 2009-2010 年 NHS 信托机构的入院总数。计算每入院的引文数量，并将其用作学术产出的指标，因为这反映了信托机构的工作量。
进行 Spearman 等级分析，以确定每入院引文数与四种死亡率的倒数之间的任何相关性：高危情况，r = 0.20（P = 0.01）；低危情况，r = -0.06（P = 0.46）；手术后死亡，r = 0.193（P = 0.019）；以及总死亡率，r = 0.291（P < 0.01）。
这项初步研究的结果表明学术产出与死亡率之间存在显著相关性。相关系数较小，但该研究的发现鼓励进一步讨论。
