A survey of hundreds of doctors across Europe found 60% admit to using Wikipedia for reference. In the UK the figure is one in two.
Dr Douglas Diggle, a GP from West Yorkshire, explained on BBC Radio 5 live why he finds the website useful: "The information... is highly technical."
"We do have journals that are published every week," Dr Diggle told the Morning Reports programme.
"Any legitimate way of sourcing information is OK."
