Official notice

The VA Palo Alto Health Care System, a Veteran’s Affairs facility and covered entity (CE), reported a breach incident affecting 1,600 individuals in December 2017. During a mass mailing to recruit for a research study, the research study worker used an electronic mail merge and mixed up names and addresses on mailed postcards. The postcards contained protected health information (PHI), including clinical and demographic information. The VA provided breach notification to individuals, HHS, and the media. OCR obtained assurances that the VA took voluntary corrective action by re-sending the postcards correctly, training research study staff on proper handling of PHI and on the mail merge system, and revising its procedure so that a second person checks mail merged documents against a master list before mailing.
