Millions of Americans access the Internet forhealth information, which is changing the waypatients seek information about, and oftentreat, certain medical conditions. It isestimated that there may be as many as 100,000health-related Web sites. Theavailability of so much health informationpermits consumers to assume more responsibilityfor their own health care. At the same time,it raises a number of issues that need to beaddressed. The health information available toInternet users may be inaccurate orout-of-date. Potential conflicts of interestresult from the blurring of the distinctionbetween advertising and professional healthinformation. Also, potential threats to privacymay result from data mining. Health care consumers need to be able toevaluate the quality of the informationprovided on the Internet. Various evaluativemechanisms such as codes of ethics, ratingsystems, and seals of approval have beendeveloped to aid in this process. Theeffectiveness of these solutions is evaluated inthis paper. Finally, the paper addresses theimportance of including patients in developingstandardized quality assurance systems for online health information
