EXCERPT FROM PAPER :
“In this issue of the Anaesthesia and Intensive Care, Bain and Myles have
assessed the relationship between impact factor and publication type with
respect to evidence-based medicine level in anaesthesia.  They found that ,
although the evidence of human studies published in anaesthesia journals
was high, there was no correlation between the evidence-based medicine
level of publication in an anaesthesia journal and the impact factor of
that journal.  This suggests that the impact factor does not reflect a
journal’s quality if evidence-based medicine is considered to be a measure
of scientific quality.  However, these two studies were limited by the use
of publications from a six-month (in 2000) or one-year period (in 2003).

The impact factor is therefore a useful measure of the quality of
scientific journals, but on its own provides a very limited idea on the
extent to which the papers are useful for clinical relevance and daily
practice.  Alternative bibliometric measures (such as citation half life,
the total number of citations, “electronic hit data”) should also be
considered.  More attention should be given to the clinical relevance and
social impact of research in all medical journals.

Measuring something as subjective as the quality of the written word is as
fraught with dangers as attempting to measure beauty.”
