(AP) The University of Virginia Medical Center is warning patients that an electronic device containing their medical and personal information is missing.
The hospital began notifying patients on Friday about the potential security breach. A call center for patients who have questions will open Monday.
The handheld device was used by on-call pharmacists at Continuum Home Infusion. It went missing around Oct. 5.
Affected patients received services from Continuum Home Infusion during September. Potential patients who were referred to Continuum Home Infusion from August 2007 through September also could be affected.
Hospital officials say in a statement that the device might have contained patients' names, addresses, diagnoses and medications, along with some Social Security numbers that also are health insurance identification numbers.
Hospital officials don't believe the information has been accessed.
