Location of Exposed and Stolen Protected Health Information
The OCR breach reports show the importance of implementing physical safeguards to ensure the confidentiality of paper records. In November, one third of reported data breaches (7 incidents) involved paper/films. Last month there were five reported incidents involving paper records.
A recent Accenture/HIMSS Analytics survey revealed email was the most common vector in cyberattacks on healthcare organizations. That was the case in October when email was the common location of breached data. In November, email was the second most common location of breached PHI behind paper films, with four email-related breaches reported. There was an even spread between all other locations of breached PHI.
