Almost no evidence exists that the internet harms health

A systematic review of medical reports produced only one case of a patient being harmed by the internet, reported Anthony Crocco of Montreal Children's Hospital at last week's meeting.

Crocco and his contributors began their study in response to the huge amount of publicity given to the harm that might be done to people by information about health on the internet that was wrong, incomplete, or impossible to understand.

They expected to find many cases of harm. But having conducted a sophisticated search of five databases, including Medline and Embase, they found only one caseof a patient with lung cancer who had ordered a drug through the internet and died from taking it.

They did find eight papers describing self injury resulting from accurate information on the internet, but the intention had existed before the internet was accessed.

Surprised by their results, Crocco and others wondered whether that meant that the internet had not caused harm, their search had been inadequate, or studies reporting harm had simply not been published. Crocco is, however, a snowboarder, and he was able to find many reports of harm resulting from snowboarding.

Some in the audience suggested that the study reflects the fact that anxiety surrounding the internet is just like the anxiety that surrounds much that is new, including videos, computer games, andyears agobicycles and books.

Another member of the audience said that with 50-100 million people using the internet and half looking for health information at some time it was inconceivable that both benefits and harms had not resulted. The important question was to measure both the benefits and the harms.
