It was stolen from a hotel while an OHSU employee was there on business.

The hospital says police believe the thief didn't know what the computer held.

OHSU said the data is password-protected and may have been deleted before the theft.

It said the data could include medical record numbers, names, telephone numbers, dates of birth, gender, medical diagnosis category and category of treatment -- but not the specific treatments, Social Security numbers or addresses.
