The purpose of this project was to assess the value of using the Web to teach older consumers about their role in preventing medical errors. Consumers were recruited from a metropolitan Detroit senior community center. The majority of the participants had little or no experience with the Internet. After being taught how to use the computer and Internet, seniors completed a Web-based intervention on quality health care and medical errors. Seniors increased their knowledge about quality care and their role in preventing medical errors and highly rated the Web sites.
