SIGAPS is a bibliometric score that aims at making an inventory, evaluating and promoting scientific publications of hospitals that perform research. It has become a major stake in France since it is one of the most important components of the MERRI (Mission Training, Research, Reference and Innovation) founding of hospitals. This score is based on the points attributed to the authors of articles published in journals indexed in Medline, according to the rank of the authors and the Impact Factor of the journal.
to compare the reliability of the score when applying different way of computing it, and different weights for the rank or the Impact Factor.
we computed the scores of all the physicians of a University Hospital, using the rules that are actually applied at the national level. We then used 4 different scenarios, with different weight given to the rank of authors or the Impact Factor. We compared the scores obtained by each author according to the different scenarios with the Spearman's rank and Pearson's correlation coefficients.
The score is not significantly affected when no points are given to the fourth authors and above, when the last author get more points or to change the points according to the Impact Factor of the journal.
The different scenarios do not lead to significant changes for the physicians' scores, and therefore for the cumulated score of the hospital. Despite the well known limits of bibliometric indicators, the SIGAPS score appears reliable to compare the hospitals for founding decisions.
SIGAPS是一种文献计量得分,旨在对开展研究的医院的科学出版物进行清查、评估和推广。自它成为医院MERRI(使命、培训、研究、参考和创新)基金最重要的组成部分之一后,它在法国已成为一项重大事务。该得分基于Medline索引期刊上发表文章的作者所获分数,依据作者排名和期刊的影响因子而定。
比较采用不同计算方式以及作者排名或影响因子的不同权重时该得分的可靠性。
我们运用国家层面实际应用的规则,计算了一家大学医院所有医生的得分。然后我们使用了4种不同的方案,赋予作者排名或影响因子不同的权重。我们根据不同方案,用斯皮尔曼等级相关系数和皮尔逊相关系数比较了每位作者获得的分数。
当不给第四及以上作者赋分、最后一位作者获得更多分数或根据期刊影响因子改变分数时,得分未受到显著影响。
不同方案不会导致医生得分出现显著变化,因此也不会使医院的累计得分出现显著变化。尽管文献计量指标存在众所周知的局限性,但SIGAPS得分在用于比较医院以做出基金决策时似乎是可靠的。
