Which method is commonly used to enhance data security in EHR systems?

Limiting access based on user roles is a fundamental practice for enhancing data security in Electronic Health Record (EHR) systems. This approach ensures that individuals can only access the information necessary for their specific job functions. By implementing role-based access control, organizations can protect sensitive patient data from unauthorized access, significantly reducing the risk of data breaches.

This method aligns with privacy regulations such as the Health Insurance Portability and Accountability Act (HIPAA), which mandates that healthcare entities safeguard patient information. By restricting access, EHR systems can maintain a higher level of confidentiality and integrity, enhancing overall data security and fostering trust between patients and healthcare providers.

In contrast, using paper files, allowing unrestricted access, or storing records on unsecured external drives would compromise data security, making sensitive information more susceptible to theft, loss, or unauthorized viewing.
