The Medical Home Portal is a web site aimed at supporting physicians and families in improving the care and outcomes for children with special health care needs (CSHCN) in the Medical Home model. To optimize access to its information and resources, the content has been structured using XML schemas that incorporate relevant clinical questions. This approach guides authors as they develop content and informs the organization of the site, aimed at assuring that users can readily locate needed information and resources. It will also enable direct access to relevant content via "infobuttons" or a questions-based interface, and extraction of content for use in electronic health records or other electronic media.
