Several computer discs and tapes were reported stolen from Providence Health System in 2006.
The lost storage media contained confidential medical records of 365,000 patients.
The breach occurred when a car prowler broke into a van parked overnight at the home of a Providence employee who left computer disks and data tapes in the van.
The records, some going back 20 years, contained Social Security numbers and medical information for 365,000 people.
The ensuing uproar triggered a state and federal investigation and helped convince lawmakers to enact stronger privacy protections in Oregon.
Oregon's Supreme Court upheld the dismissal of lawsuit seeking compensation for tens of thousands of people whose confidential records were stolen from Providence Health & Services in 2006.
The court said the civil lawsuit failed to show that stolen information was used or even viewed by a third party, and thus failed to substantiate a negligence claim.
A Multnomah County judge struck claims for damages in 2007, concluding that the nonprofit hospital corporation had already reasonably compensated the affected patients and employees and corrected the security problems.
Providence provided two-years of credit-protection services to all whose records were stolen and paid more than $195,000 to settle state and federal investigations of security lapses.
