When was content written?
Medicine is a fast-moving field so check the date of content and when it was last revised. Be cautious of anything more than a couple of years old.
Who is behind the site?
Go to the ‘About’ section and check. Are they doctors or recognised experts? Why did they set up the site? Where is it based – the UK or elsewhere? Bear in mind treatments and procedures recommended on foreign sites can be different to those found in the UK.
What action does the site want you to take?
If the site is run by a company that wants you to buy a drug or treatment, check with your GP first.
Does the site look professional?
Avoid sites with spelling mistakes and poor grammar and any without a contact address, email, and/or telephone number, but perhaps just a Webmaster email.
Is there any way to check content?
Content should be traceable. Look for references and links to peer-reviewed articles in respected medical journals so you can check accuracy.
Does the website promise more than it can deliver?
Steer clear of sites that offer solutions to medical problems that sound too easy or outlandish. Be wary of terms such as ‘miracle cure’ or claims that you can solve complex issues with ‘one simple tip or trick’. Titles such as ‘Centre’ or ‘Foundation’ can be pretty meaningless.
Is it accredited?
Health information on the internet is unregulated but there are a couple of accreditation logos that show websites are transparent and evidence-based. Look for the ‘Information Standard Certified Member’ logo. This shows the site has been through NHS England's rigorous accreditation process. The Health on the Net Foundation code of conduct for medicine and health (healthonnet.org ) is an international ethical standard.
