Quality of online information about migraine headache surgery.

Migraine headache is a debilitating disease that can lead to severe functional limitations and is the most common primary headache. In more than 30% of cases conservative therapies do not allow the control of symptoms or cause side effects. Peripheral nerve surgery should be considered in non-responsive chronic migraine or suspected peripheral origin. Nowadays Web has become one of the most important sources of knowledge for patients: the information available on the web is not subject to a control of the sources reliability but can influence the patient. The aim of the study is to evaluate the quality of information accessible on the Web about the surgical treatment of migraine headache. "Headache OR migraine treatment", "headache OR migraine surgery" were the keywords used on two main search engines (Google and Yahoo). Among the first 50 websites, 26 were suitable and we divided them into five groups (practitioners, hospitals, healthcare portals, professional societies, encyclopedias). We applied the expanded EQIP (Ensuring Quality Information for Patients) scale: the EQIP scale consists of 36 questions with three sections (content, identification data and structure). Although the overall average score was relatively high (22 out of 36), many lacks information were highlighted: overall, readability was not satisfactory in communicating information regarding migraine and its surgical treatment. Readability should be tested before medical online publication, in order to provide for its correct use by the patient and improving migraine knowledge.
