MidState Medical Center announced this week that an employee who wanted to work at home improperly transferred information on 93,500 patients to a personal hard drive. The information transferred outside the hospital?s secure computer system included patients? names, addresses, dates of birth, Social Security numbers and medical record numbers. A spokesman for the hospital, which is affiliated with Hartford Healthcare, said that the person who took the hard drive was a Hartford Hospital employee and was dismissed following an investigation by a private security firm. The hard drive has not been located, according to MidState, but the hospital has no evidence that any of the personal information has been misused. The hospital is sending letters to the 93,500 patients, advising them of the possible compromise of their information and offering them two years of an identity protection service.
