By Alexi Cohan | [email protected] | Boston Herald August 22, 2019 at 6:35 pm Massachusetts General Hospital is notifying nearly 10,000 people of a privacy breach involving its department of neurology. An unauthorized third party gained access to databases used by MGH researchers that may have included a host of information such as the participant’s name and personal information, dates of study visits and tests, medical record number, diagnosis and medical history, biomarkers and genetic information, the hospital said in a statement Thursday. The investigation into the privacy incident revealed that the third party accessed the data between June 10 and 16. Some of the information reflected subjects that had participated in studies years ago. For deceased research participants, the data included date of death, and, when available, a summary of autopsy results. The data did not include anyone’s Social Security number, insurance information or financial information. It did not include any contact information for the participants of the research or MGH’s medical records systems. The hospital conducted an investigation and said it continues to review and improve security for its research programs. MGH is still in the process of notifying those affected.
