Preamble
Dear Colleague,
Evidence from prospective randomised trials forms the basis for
our therapeutic decisions in individual patients.
Over the past 20 years a great number of important prospective randomised
trials have been performed in the field of cardiology.
In guidelines resulting from these trials, experts
rate the available evidence and give recommendations regarding the
choice of diagnostic and therapeutic options.
In order to access this wealth of evidence, it is critical to expand
the methods for sharing information, especially when the time window
for decision-making is narrow. Furthermore, quickly accessible and
specific data are needed to ensure that a given patient’s
characteristics conform to those of the patients treated in a given
clinical trial, and therefore that similar treatment effects can
be expected.
The pilot project presented here offers quick
and structured access to the ESC-guideline on acute coronary syndromes
without ST-elevation. There is also a database containing the prospective
randomised studies on use of GP IIb/IIIa antagonists in acute coronary
syndromes.
This is not an “expert system” but aims to support the
expert in getting the specific information needed to treat individual
patients.
The principal rules for construction of the database
(Systematic Trial Analysis and Review, STAR®) were:
- Inclusion of studies according to the grade of evidence. This
database includes only studies of grade 1 evidence (according
to Sackett, prospective randomised trials, metaanalysis).
- Only data from original full paper publications are presented
(no data on file, personal communications, etc.).
- Study presentations always follow the same sequence (see menu
on the left side of the screen), facilitating access to specific
data and their comparison to other studies.
- All numbers, figures and tables mentioned in a study are shown
in full. From the “Patients and Methods” section,
the relevant original wording is selected. This process of selection
is currently under evaluation by the Institute for Language Processing
of the University of Cologne, using methods of context sensitive
language analysis.
- Studies have been included that contain at least a subgroup
with an acute coronary syndrome.
- All studies can be compared with one another at the same level
(e.g. inclusion criteria, baseline characteristics, etc.).
- Studies dealing with the same clinical scenario (e.g. early
intervention) can be compared to one another in a split screen
version.
Last but not least, we kindly ask you to answer
the survey, which will help the ESC and the authors of this
project to further develop this tool according to your needs. As
a next step in this process it is intended to program a search facility
in order to find the specific information wanted even more quickly.
