Why you received this letter
The American Association of Critical-Care Nurses (AACN) is a professional organization serving as a specialized healthcare association for nurses who care for acutely and critically ill patients. As a professional body that manages certifications, membership records, and educational resources, the organization typically collects and stores sensitive personal information, including professional credentials, contact details, and financial data used for membership dues and certification fees. In 2025, the organization officially reported a data security incident to the Oregon Attorney General. If you have received a formal data breach notification letter, it indicates that your personal information may have been involved in this incident. This notice is intended to inform you of the nature of the event and the steps the organization is taking to address the security of your data.
What to do after the letter
