Quality and safety of health information on the Internet: Who decides and how? Role of standards, consumer education and media literacy
• Where are we? • (What examples do we have in Africa, and elsewhere?)• What are the issues and challenges to addressed?• What actions need to be taken and by whom?
Digital health information
• For health professionals / researchers
• For consumers
The ethnic theory of plane crashes (Chapter in “Outliers” by Malcolm Gladwell)
“The single most important variable in determining whether a plane crashes is not the plane, it's not the maintenance, it's not the weather, it's the culture the pilot comes from. Planes are flown safely when the pilot and co-pilot are in open and honest communication. And in cultures where it is difficult for a junior person to speak openly to a superior, you have lots of plane crashes.”
(Source: Gladwell)
Power Distance Index (P.D.I.) [Geert Hofstede] =measurement of how much a particular culture values and respects authority.Countries with a high P.D.I. generally value being more deferential towards authority, and thus not contradicting a superior.
Analogies to Healthcare
• Pilot = health care professional
• Co-pilot = patient
• Power Distance = Inverse Patient Empowerment
Eysenbach. Random Research Rants (Blog)http://www.webcitation.org/5h5jkooUX
Why patient empowerment / patient involvement?
• Safety/Quality
• Trust
• Health Outcomes?

Approaches for ensuring quality information
• Intermediation– Seals– Certification– Top-level domains
• Apomediation– Consumer education– Peer-to-peer approaches / collaborative
filtering/ social networking & filtering– Semantic web
Standards
• Instruments and checklists that can be used during material development– HON Criteria (Health on the Net Foundation)– SAM Suitability Assessment of Materials (Doak, 1993) – Mitretek Criteria (Rippen et al., 1997)– Patient Information Checklists Coulter et al. 1998– DISCERN (Charnock, 1999)– CREDIBLE Algorithm (Eysenbach, 2007)
Is a health website CREDIBLE?
• C urrent and frequently updated• R eferences cited • E xplicit purpose and intentions of the site• D isclosure of developers and sponsors• I nterests disclosed and not influencing objectivity
(e.g. financial interests)• B alanced content, list advantages and
disadvantages• L abeled with metadata• E vidence-level indicated

• Where are we? • (What examples do we have in Africa, and elsewhere?)• What are the issues and challenges to addressed?• What actions need to be taken?
Recommendations / Questions
• Challenges (ehealth literacy, access) in Africa considerable, but mobile technologies present opportunities
• Training programs and information material for proxies (community nurses, chiefs/multipliers)
• Role of enduser/patient/citizen participation in Africa? (“Web 2.0” approaches for a mobile environment, Twitter-like)
• Good governance to stimulate high quality, accessible health information includes policies that foster/encourage apomediation models (crowdsourcing, bottom-up approaches)– E.g. making 1:n SMS affordable, developing an African Twitter-
like peer-to-peer service for SMS• Quality criteria for African content? (culturally sensitive, special
usability considerations)• Technology and innovative programs
