Descriptive Information
Brief Title Tailored Internet Information Supply for Patients
Official Title Study of the Quality of Self-Diagnosis by Headache Patients Getting Tailored Internet Information
Brief Summary Medical expert systems in combination with portal searching meta-search engines are exploited to provide reliable patient-tailored information. A prototype of a web-based information system has been developed and is to be evaluated. Its aim is to answer the decisive question whether expert system guided internet meta-search provides a better information supply for patients seeking health information online then this is possible by using ordinary search engines or health portals. The research does neither investigate the influence of ethical nor legal aspects of internet health information supply.

Study Population

All German speaking adults in the German-speaking part of Europe who suffer at least occasionally from headaches and have not been examined (concerning these headaches) by a physician yet.

  • The population of the main study is narrowed down to a heterogeneous group of insurants of a health insurance company.
  • The population of the online study is self-selecting.
Condition Headache
Intervention Other: Expert system guided tailored information
The prototype is realised by a web-based information system. The HTML web-interface guides the user through the search process by querying the information demand. This is done by an integrated expert system. The expert system uses a rule based inference to determine an internal diagnosis. Based on this internal diagnosis the system searches quality labeled websites and presents relevant information to the user.
