Rapid Response:

Anxiety about quality and accuracy of medical information on the Internet will go down in the future

Accordingly with editorialists’ point of view (1) anxiety about
quality and accuracy of medical information on the Internet will go down
in the future. Taking into account an historical perspective - Purcell et
al took the telegraph example but I suggest one better as the first
movable type cast in metal invented in the 1400’s by Gutenberg - they
conclude that the majority of these engines finish being rendered obsolete
by newer technologies. Exactly in the same way as the social effects that
invention produced, against of for.

Really, in 1997 Impicciatore et al opened the Pandora box when they
reviewed the Internet as a source of health information (2). However, an
historical outlook also may be useful to give the realistic weight to this
sort of papers. Conducting a simple seek by means of Medline database you
can find a few number of papers devoted to the same problem of quality and
accuracy of health information, but in other sources of information as
mass media.

In 1990, Gunderson-Warner et al concluded that the teratogen
information available in 15 popular magazines, issued in 1985 regarding
exposures in pregnancy, was frequently misleading, alarming, and
unsupported by the scientific literature (3). Concretely, 55.4% of
articles reviewed were scored as misleading or inaccurate. It is of
interest to note that five years after this paper Hothan proceeded in the
same manner with 14 highest-circulation popular magazines in Australia
(4). However, in this occasion he found that 77.6% of articles, which
offered information on drugs and environmental influences in pregnancy,
were rated as accurate, while only 2.7% were rated as anxiety provoking or
inaccurate.
Other reviews published in the BMJ, as papers or letters, have showed
their reservations about quality and accuracy of medical information in TV
programmes (5-7).

Several readings may be done subsequent to the above comments.
Firstly, the referred problem of Internet is the same old problem of other
non-medical or non-scientific sources of health information. Secondly,
There are some doubts about a victorious effect of papers for improving
quality and accuracy of healthcare information in mass media, including
the Internet. As the web editor of the BMJ, Tony Delamothe, has repeated
in some occasions: As for any other medium it varies widely, regulation
does not seem like the right strategy for improving it.

In conclusion, It would be obtuse to select the Internet as the
target to propose a regulatory strategy.
