Health Exchanges' Sharing of Patient Data Heightens Privacy Concerns

Victor Hand, a semi-retired railway manager in Maine, grew so alarmed when he learned that his state was building a database to store all residents' medical files that he rushed to the hospital to try to opt out.

"I sure don't want my information in that thing," Hand said. "I just don't think they can keep it private. If I knew for sure that nobody could get it but my doctors, then maybe I'd participate, but there's no way to guarantee that.''
