Some patients who stayed at the Carle Foundation Hospital from November 1 of last year, through this past January, may have had their confidential information breached. Carle officials say files including names, medical record numbers and reasons for visits were shared with vendors who did not have a business reason for it. The files were placed in a company server in February and Carle learned about the breach, in June. Carle does not believe the information was used, but is working with vendors to make transfers more secure.
