Which statement best describes the benefit of EHRs for data sharing?

• A. They reduce data access
• B. They provide access to a complete health history across providers
• C. They eliminate privacy protections
• D. They increase data fragmentation

Answer: (B)

Electronic health records enable data sharing by giving authorized clinicians access to a patient’s complete health history across multiple providers. This visibility supports continuity of care, since important information like medications, allergies, prior diagnoses, and test results are readily available wherever the patient receives care. It also helps reduce unnecessary duplicate tests and potential medication errors, improving safety and coordination.

Privacy protections and access controls are still essential; sharing occurs only for appropriate, authorized purposes.

The other statements don’t reflect the benefit: reducing data access would hinder continuity of care; claiming privacy protections are eliminated ignores safeguards designed to protect patient information; and increasing data fragmentation is the opposite of the goal, which is to have a cohesive, shareable record across providers.
