Jefferson Center for Mental Health in Colorado recently notified HHS of a breach affecting 546 patients.
A statement on their web site explains:
On December 13, 2010, a paper list with brief demographic information was stolen from a locked vehicle. The thief stole a purse containing cash and a work bag of a Jefferson Center staff member which contained the list. A police report was filed and to this date no problems with the list have been reported. Letters were sent to the last address for all people on the list. Staff are trained in taking care of information when they are hired, annually, and receive updates during the year. We have reviewed our policies with staff about securing information. If you have other questions, please call Vicki Rodgers at 1-800-201-5264 for further information.
