Tailored Internet Information Supply for Patients

June 15, 2009 updated by: Health & Life Sciences University, Tryol

Study of the Quality of Self-Diagnosis by Headache Patients Getting Tailored Internet Information

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 Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

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.

Description

Inclusion Criteria:

  • Age between 18 and 75
  • Suffers at least occasionally from headaches
  • Has internet access
  • Has not obtained a medical diagnosis (concerning this headache) by a physician, yet

Exclusion Criteria:

  • Age under 18
  • Age over 75
  • Does never suffer from headaches
  • Has no internet access
  • Has already gotten a medical diagnosis for her/his headaches

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Main 1
Insurants of the health insurance company BARMER using the prototype to receive expert system guided tailored internet information about the type of headache they suffer from.
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Conformity of self-diagnosis and medical diagnosis
Time Frame: After medical diagnoses has been received
After medical diagnoses has been received

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
