In February, staffers at Fairview Health Services in Minneapolis packed up about 1,200 patient records for shipping to a new office across town.
Unfortunately, no one at Fairview has seen the box since.
This week, officials began notifying patients that their health and billing records -- including names, birthdates and medical diagnoses -- may have been lost.
Officials say there's no evidence of any misuse of the records, which involved patients admitted to Fairview Southdale Hospital in Edina between April 2010 and February 2011.
Still, mindful that medical privacy and identity theft have become prickly topics, Fairview is offering the affected patients a free year's subscription to an identity protection service.
"We firmly believe that there is no financial risk to these patients," said Lois Dahl, Fairview's information privacy director, noting that the records did not include Social Security numbers or credit card information.
On Wednesday, Fairview issued a written statement saying it "takes this incident very seriously."
Fairview officials have been searching for the box since it was reported missing Feb. 21. By federal law, the hospital has 60 days to notify patients of any security breach involving their patient records, Dahl said.
