Web searches feed health fears

Health information online is breeding a generation of cyberchondriacs - people who needlessly fear the worst diagnosis after surfing the net, say researchers.

A team at Microsoft studied health-related Web searches on popular search engines and surveyed 515 employees about their health-related searching.

Web searches had the potential to escalate fears - like a headache was caused by a brain tumour, for example.

Experts said people concerned about their health should see a doctor.

Self-diagnosis by search engine

Microsoft conducted the study to improve its own search engine.

Roughly 2% of all the Web queries were health-related, and about 250,000 users, or a quarter of the sample, engaged in a least one medical search during the study.

The researchers found Web searches for common symptoms such as headache and chest pain were just as likely or more likely to lead people to pages describing serious conditions as benign ones, even though the serious illnesses are much more rare.

Searching for "chest pain" or "muscle twitches" returned terrifying results with the same frequency as less serious ailments, even though the chances of having a heart attack or a fatal neurodegenerative condition is far lower than having simple indigestion or muscle strain, for example.

About a third of the 515 Microsoft employees who answered a survey on their medical search habits "escalated" their follow-up searches to explore serious, rarer illnesses.

Although the work does not give firm proof that searching the web increases health fears - users may simply be curious about a condition - the researchers say it is likely in some circumstances.

"Our results show that Web search engines have the potential to escalate medical concerns," said Eric Horvitz, an artificial intelligence researcher for Microsoft.

Trusted sources

A spokeswoman from NHS Direct said health information on the Web was no substitute for expert advice.

"It is always a good idea to talk to a clinician who can point you in the right direction if you are concerned about your health.

"The Web can be a useful tool to find out more information about conditions, but it should not replace talking to an expert."

Henry Scowcroft, of Cancer Research UK, said trusted patient information websites could be useful resources.

"Paradoxically, the problem in the UK is that many people are still unaware of the symptoms of cancer, and delay in seeing a doctor is one of the key reasons why this country's cancer survival figures lag behind the best in Europe.

"It's important to study this area further, but we must also remember that many people still have no access to the wealth of information online, and that health inequalities - including inequality of information access - are widening, not narrowing."

The World Wide Web provides an abundant source of medical information. This information can assist people who are not healthcare professionals to better understand health and disease, and to provide them with feasible explanations for symptoms. However, the Web has the potential to increase the anxieties of people who have little or no medical training, especially when Web search is employed as a diagnostic procedure. We use the term cyberchondria to refer to the unfounded escalation of concerns about common symptomatology, based on the review of search results and literature on the Web. We performed a large-scale, longitudinal, log-based study of how people search for medical information online, supported by a large-scale survey of 515 individuals’ health-related search experiences. We focused on the extent to which common, likely innocuous symptoms can escalate into the review of content on serious, rare conditions that are linked to the common symptoms. Our results show that Web search engines have the potential to escalate medical concerns. We show that escalation is influenced by the amount and distribution of medical content viewed by users, the presence of escalatory terminology in pages visited, and a user’s predisposition to escalate versus to seek more reasonable explanations for ailments. We also demonstrate the persistence of post-session anxiety following escalations and the effect that such anxieties can have on interrupting user’s activities across multiple sessions. Our findings underscore the potential costs and challenges of cyberchondria and suggest actionable design implications that hold opportunity for improving the search and navigation experience for people turning to the Web to interpret common symptoms.

Really true. I got friends and even my mother looks in some answer in the net all about their health. After that they always cautious on what they eat. For the readers, I really suggest see a doctor first and don't get paranoid.

Yep, my mother too. She now thinks she has just about every medical condition you could have at 60... which is just about everything!
