The computer belonged to a university employee traveling in Chicago on business, The (Portland) Oregon reported Saturday.

The computer was password-protected and did not contain Social Security numbers, addresses or treatments, the university said in a letter notifying patients of the theft.

As a precaution against information theft, the records of the 890 patients have been flagged in the university's system to ensure requests about them automatically receive greater attention from security officials, the Oregonian reported.
