Billing records of 2.2 million people at the University of Utah Hospitals & Clinics were stolen from a courier's vehicle, authorities said Tuesday.
The records, described only as backup information tapes, included Social Security numbers of 1.3 million people treated at the university over the past 16 years, said Lorris Betz, senior vice president for health sciences. The records also involved people responsible for paying for treatment, such as parents of minors.
Those affected will be notified by letter and the hospital will offer them free credit monitoring, Betz said.
The courier picked up the records on June 1. Instead of taking them to a storage center, he worked a second job and then went home, said Shane Manwaring, Salt Lake County deputy sheriff. The next day, he discovered that someone had broken into his vehicle outside his Kearns home and taken the box, Manwaring said.
Authorities declined to say how easy or difficult it would be to read the records.
