Disclosed Mar 28, 20188 years ago2,527 affectedConfirmed
In 2017 the Everett Police found a computer hard drive that contained the protected health information (PHI) of 2,280 patients of Cambridge Health Alliance, the covered entity (CE). The CE's information security team's review of its systems did not identify any potential avenues through which this information may have left the organization. The types of PHI that were potentially exposed included patient billing information from 2013 which included clinical information related to emergency department visits. The CE provided breach notification to HHS, affected individuals, and the media. OCR obtained assurances that the CE is reviewing its HIPAA Privacy and Security training to ensure that the training adequately covers potential risk areas.
