March Healthcare Breaches and Hacking Incidents

While health plans were most affected by March healthcare breaches, the most common cause behind all of March’s breaches were hacking incidents.

March Healthcare Breaches and Unauthorized Access or Disclosure of PHI

Incidents of unauthorized access or disclosure of protected health information (PHI) occur when PHI is accessed or disclosed without necessity. These types of incidents can occur when an employee accesses a patient’s medical records outside of their job duties, or when an unauthorized entity accesses patient information. For example, if a doctor’s office leaves paper charts in an area that can be accessed by non staff members, and someone views those records, that is a reportable incident of unauthorized access or disclosure. 

In March 2021, there were 17 incidents of unauthorized access or disclosure of PHI representing 1.52% of reported incidents. These types of incidents affected 44,395 patients.
