UnitedHealth Group is giving a one-year grant of $400,000 to the web based program called Health Shack. It’s an online hub for homeless and marginalized teenagers to keep their medical documents, called e-records. That way when they go to a hospital or clinic doctors can find their information online. And that can help the teens better manage chronic diseases like diabetes or mental illness. The site also keeps track of immunizations and school records. A local center for homeless teenagers - WIND Youth Services – is leading the initiative. UC Davis Children’s Hospital and the non-profit group Linkage to Education are also helping. Currently about a hundred teenagers are using the program. Health Shack hopes to enroll a couple hundred more teens in the coming year.
