Name one compliance regulation that affects EHR usage.

One significant compliance regulation that affects EHR usage is HIPAA, which stands for the Health Insurance Portability and Accountability Act. HIPAA sets the standard for protecting sensitive patient health information. It outlines requirements for healthcare providers, health plans, and other entities to ensure that personal health information is securely handled and stored, particularly in electronic formats such as Electronic Health Records (EHRs).

HIPAA mandates that healthcare organizations implement safeguards to protect patient data, including physical, administrative, and technical protections. This regulation ensures that patients' privacy is maintained, and unauthorized access to their health information is prohibited. Compliance with HIPAA is crucial for EHR systems, as these systems must have robust security measures in place to guard against data breaches and unauthorized disclosures.

In contrast, while the other regulations mentioned play important roles in various sectors, they do not directly regulate the use of EHRs in the context of patient information privacy and security in the healthcare domain.
