Medline and PubMed will be able to synthesise clinical data
EDITOR
In
their editorial Smith and Chalmers call for a new and most welcome initiative
that would provide access to a synthesis of valid, relevant clinical
information.1 Those of us responsible
for the original Medline database wish success to any endeavour that
hopes to transform health care (and that might bring honour to the
Queen). Your readers might be interested to learn about some recent
improvements of our own in this direction.
The US National Library of Medicine began to link sources on the internet
from the inception of free PubMed access to Medline in 1997. (It was
vice president Al Gore, not the then first lady Hillary Clinton, who
announced free access to Medline via PubMed at a ceremony in the US
Congress.) The LinkOut feature of PubMed is designed to provide users
with a wide variety of relevant web accessible resources, including
full text articles, biological databases, consumer health
information, research tools, and more. PubMed also links users to an
extensive database, ClinicalTrials.gov,
which provides patients, family members, and the general public
with current information about clinical research studies. In 2002 PubMed
citations will include links from the American College of Physicians
Journal Club and other evidence based medicine journals to the
original journal article being commented on.
Late in 2001 we complemented our "clinical queries" feature, which filters
references using a method based largely on the work of Haynes et al,
with a new filter called systematic reviews.2
This feature has much the result in mind as the proposal by Smith
and Chalmers
the
ability to retrieve systematic reviews and meta-analysis studies for
a specific search topic. Since the systematic reviews filter is so
new and as yet unpublicised, they were not mentioned in the
editorial. The Cochrane Database of Systematic Reviews, which
has been indexed in Medline since 2000, is among the evidence based
resources. Moreover, Clinical Evidence has been approved for
indexation in Medline, and its citations, with full text links, will
begin to appear in PubMed early in 2002.
