The march 11 theft of an external hard ride used for backing up the Clinic's electronic files may have exposed patient information. The hard ride was stored in a locked, fire-protected building with very limited access. Many of the files contained patient social Security numbers in addition to names, dates of birth, addresses and other clinical information. There was a postponement in notification due to the fact that there were duplicate files and patient contact info had to be updated. The Clinic has begun to encrypt records and raised the physical security of the files since the incident.
