From their press release, issued yesterday:
Lucile Packard Children’s Hospital at Stanford and the Stanford University School of Medicine are notifying patients by mail that a password-protected laptop computer containing limited medical information on pediatric patients was stolen from a physician’s car away from campus on the night of January 9, 2013. This incident was reported to Packard Children’s and the School of Medicine on January 10. Immediately following discovery of the theft, Packard Children’s and the School of Medicine launched an aggressive and ongoing investigation with security and law enforcement, and began contacting patients potentially affected.
The medical information on the stolen laptop was predominantly from 2009 and related to past care and research. The patient data did not include financial or credit card information, nor did it contain Social Security numbers or any other marketable information. It did include names and dates of birth, basic medical descriptors, and medical record numbers, which are used only by the hospital to identify patients. In some cases, there was limited contact information. There is no indication that any patient information has been accessed or compromised.
They also posted an FAQ on their site, which says, in part, that 57,000 patients are being notified.
