Massachusetts General Hospital (MGH) is deeply committed to the security and confidentiality of our patients’ information, including any such information maintained by our third-party vendors. Regrettably, this notice concerns an incident involving some of that information.
Patterson Dental Supply Inc. (PDSI) is a trusted third-party vendor that provides software that helps manage dental practice information for various providers, including MGH. On February 8, 2016, we learned that an unauthorized individual gained access to electronic files used on PDSI’s systems, which we later confirmed contained some MGH dental practice information. PDSI reported the incident to law enforcement. Thereafter, law enforcement investigators required that any notification to potentially affected individuals and any public announcement of the incident should be withheld while they were conducting their investigation. On May 26, 2016, law enforcement gave permission to notify, and we began notification as quickly as possible once we completed our investigation.
Based on our investigation, with the cooperation of PDSI, we determined that the files stored by PDSI included limited information related to some of our dental practice patients. That information included patient name, date of birth and Social Security number and, in some instances, may have also included date and type of dental appointment, dental provider name and medical record number. This incident did not involve any unauthorized access to any of MGH’s systems or to any files maintained by MGH.
We are committed to the security of sensitive information maintained by our third-party vendors and are taking this matter very seriously. To help prevent this type of incident from happening again, PDSI took steps to enhance the security of its systems that maintain dental practice data.
We regret any inconvenience caused by this incident. We began mailing letters to affected individuals Wednesday, June 29, 2016, and we have established a dedicated call center to answer any questions they may have.
